Black Source Laboratory.

In the glass cover used to cross the demon, Lin You was fully focused, stimulating his magic power and spiritual power. As the demon shell vibrated, the two forces quickly resonated.

With the attachment of soul power, the magic power in this environment became much lighter and kept vibrating.

With each tremor, over ten points of magic power flew out.

In the fog of demon crossing, there are often two or three more points flying each time.

But even without those two or three extra points, Lin You's current efficiency in transferring magic power was already jaw-dropping.

Today is the thirteenth day of such transportation.

Just today, while Lin You was in the process of overcoming the demon, he could already feel that the demon shell had become extremely light.

This means... the magic power is about to be exhausted!

Outside the glass cover, Heiyuan was staring at Lin You inside. He could sense some conditions on Lin You's body.

After witnessing this astonishing speed of demon crossing, even though it had been more than ten days, Heiyuan still couldn't help but sigh.

Too fast!

It’s too fast!

It seemed that the demon-crossing stage of the combination of spirit and demon was just a small threshold for Yu Linyou.

It is true that you need to lift your legs, but that is all.

10 o'clock, 11 o'clock, 10 o'clock!

The magic power was transferred in waves, and the sky outside gradually darkened.

Finally, when another amount of magic power flew out from the magic shell and injected into the source of the soul, the entire source of the soul suddenly flashed with a faint blue light.

Sensing this and realizing that the magic shell was completely empty, Lin You knew that the magic crossing was completed.

An ordinary leap!

The expected sequence of achievements did not appear.

Lin You felt a little regretful, but didn't care too much.

I had already made some mental preparations. After all, when I first entered the stage of combining spirit and devil, I had already activated a top-level achievement sequence related to the advanced card roulette.

If he wants to rely on the combination of spirit and devil to activate the achievement sequence again, he may have to wait until he transfers the magic power into the source of the soul, merges it into the energy of the combination of spirit and devil, and then returns it to the devil shell before he can do so.

This is a big project!

Even though he easily completed the demon crossing, Lin You did not underestimate the difficulty of combining the spirit and the demon.

Especially the perfect combination!

These next two steps are the key.

No, to be precise... it's the next step!

It's about the fusion of energy, and fusion itself is extremely difficult.

“Huh~”

Lin You let out a light breath and walked out of the glass cover.

"How does it feel?"

Watching him walk out, Hei Yuan smiled and said, "Although it's not very difficult for you to cross the demon, the magic power of your demon shell has been drained away. It must be very uncomfortable for you now, right?"

"It's a bit awkward."

Lin You nodded. After all the magic power in the magic shell was transferred, he inexplicably felt that a piece of his body was missing, somewhat similar to the feeling of a missing tooth and air leaking.

But it doesn’t matter. As long as it doesn’t affect the normal use of magic power, it’s nothing.

Thinking of this, he couldn't help but wonder, "It's really interesting, though. It's clearly been transferred out of the magic shell and placed in the source of the soul, yet the magic power can still be used, and I can still enjoy the magic power amplification effect brought by the magic shell as usual."

"That's normal."

Hei Yuan casually explained, "There's a deep connection between the Spirit Shell and the Demon Shell, otherwise they wouldn't be able to combine like this. Isn't the Demon Shell's effectiveness and power based on the duelist's innate soul strength? Why are those with an innate demonic physique naturally suited to absorbing magic power? Isn't it because of their naturally different soul strength?"

As he spoke, he seemed to feel that he had said too much. He coughed dryly and continued, "Of course, soul strength doesn't affect everything, but it is undeniable that soul strength is the dominant factor in whether a duelist's talent is outstanding."

Lin You laughed and said, "Teacher, what you said makes the Demon Shell seem to have become a byproduct of the Spirit Shell."

"That's not the case. It's more like they complement each other."

Hei Yuan denied it immediately, but then added, "But the Spirit Shell's contribution is greater, there's no doubt about that, not to mention the Soul Source. The Soul Source can actually devour the Spirit Shell!"

As a psychic, Heiyuan was quite confident and proud when talking about this aspect.

"indeed."

Lin You did not deny that the importance of soul strength was reflected in all aspects.

"It's already August 18th..."

Hei Yuan didn't mention the soul strength anymore, but said with a hint of regret, "It's still nearly ten days late. Although I know you're not the type to care about these things, I still want to apologize."

"Teacher, what happened to you suddenly?"

Hei Yuan's sudden apology left Lin You stunned.

What's nearly ten days late?

Seeing his puzzled look, Hei Yuan suddenly laughed and said, "Life still needs a sense of ritual from time to time. Although I simply celebrated your birthday that day, it stands to reason that I should have completed something I had wanted to prepare for you for a long time."

Birthday?

Lin You was stunned. He didn't expect Hei Yuan was talking about this.

The 10th was indeed his birthday, but Heiyuan also celebrated for him that day.

I even specially got him a rare cake from a secret place. The cake was incredibly huge.

There must be more than ten layers, and the smallest layer is as big as a millstone!

How could Lin You finish such a cake? Although he used magic to speed up the digestion, it was still a small matter.

But in order to digest food, you have to use magic power. Isn't that too much time?

Just thinking about it makes me feel like it’s a waste!

Fortunately, there is Chestnut Ball.

Although this little guy has eaten a lot of good things recently, including the source of darkness and two types of super source power, sweets are still very much to his taste.

The huge cake was also eaten up completely by the little guy.

At this moment, Heiyuan did not explain. A light suddenly appeared on the duel disk, and a pure white bead emerged.

Seeing this incredibly familiar pure white bead, Lin You was stunned for a moment, then couldn't help but click his tongue and exclaimed, "Teacher, you got another Dao Source Bead? Why does it feel like this precious thing has become so easily obtainable now that you have it?"

"If that were true, the size of this laboratory would have expanded tenfold, even a hundredfold!"

Hei Yuan sighed, "I didn't have to sell all my property, and I had to find someone to help me get this source bead."

As soon as he finished speaking, the duel disk in his hand flashed again.

A huge stone suddenly appeared and slammed down on a nearby laboratory table, emitting bursts of pure white light.

Lin You was stunned by the huge stone, especially when he sensed the enormous energy within it. He couldn't help but exclaimed, "Teacher, this... is this a spirit stone?"

Lin You was naturally familiar with the energy emitted by the spirit stone.

But even so, when seeing this huge stone, no one can believe that it is a spiritual stone.

It’s too big!

If this kind of spirit stone is cut, who knows how many normal spirit stones it can be converted into.

However, the price of a regular spirit stone in the exchange mall of Jiangcheng University is as high as 500 duel points.

In the association's duel mall, it is more favorable to purchase it with duel merits, but it is still worth 8 merits.

Such a regular spirit stone has such value. Judging from Lin You's current experience, this huge spirit stone can be cut into at least hundreds of regular spirit stones.

Its value may exceed a thousand points of merit!

Lin You was shocked. What happened to the teacher? Was he really taking out all the money from the laboratory and showing off his wealth to him?

That's not right. Although the teacher likes to act cool on weekdays, he shouldn't be so impatient!

Isn't this boring?

etc……

Suddenly, Lin You recalled what Hei Yuan had said, which he had not paid much attention to just now.

What have you prepared for yourself?

He even chose to do it on his birthday. Could it be that...

At this moment, Hei Yuan had a calm expression. He observed Lin You's expression for a moment, and seemed quite satisfied with his surprise. He nodded secretly before saying, "Don't make a fuss. Although spirit stones of this size are rare, for a master, even if they are not common, they are not too surprising. It is perfect for you to use it to apply spiritual pressure, improve your skills, and increase your spiritual power. With this spirit stone, you don't have to worry about spirit stones when you are away for at least the next year."

Lin You quickly praised him, "Teacher, you are so generous! If all teachers in this world cared, loved, and supported their students like you do, what a dream it would be. What a pity..."

As he spoke, he shook his head slightly, "Not all teachers can do what you do."

This sounds good!

Heiyuan was happy in his heart, and although he didn't say it on his face, a smile appeared on the corner of his mouth unconsciously. But soon, the duel disk in his hand flashed again!

Teacher, do you have anything else to give me?

Lin You immediately looked over with anticipation, and after seeing what appeared, his eyes were filled with surprise, "Teacher, what is this? Such a strong spiritual energy!"

What appeared this time was a silver kitten with short hair.

The most peculiar thing is that the kitten is clearly sleeping with its eyes closed, but its two paws are firmly grasping a magic wand, and a silver circular magic circle is faintly visible under its feet.

For a moment, Lin You couldn't even tell whether this kitten was a duel monster.

If it is a Duel Monster, why don't I see the card flipping over or the light of summoning?

Even an original monster like the little guy would emit light when summoned.

It's just the time it takes to summon now, which can be ignored.

"Teacher, is this a Duel Monster?"

Lin You stared at the kitten for a while, but couldn't help but ask.

“Actually, it is.”

Hei Yuan gave the answer, then smiled and said, "It's just that there are some differences from the Duel Monsters we usually understand. The biggest difference is that this magical cat doesn't exist on the card."

"Is it an existence similar to a secret realm monster?"

Lin You immediately thought of this. As everyone knows, in today's dueling world, the main materials of the cards used by duelists are the countless monsters in the secret realm.

It is precisely because of the existence of these monsters that many new cards are born in the duel world every day.

The number of secret realms is too astonishing!

From this perspective, the war between the human world and the chaotic demon world is indeed irreconcilable.

If the dueling world is to develop, there will naturally be a lot of killings in secret realms.

But as far as Lin You knew, the reason for the unrest in the Chaos Demon Realm was not because of this. In fact, they were the ones who initiated the riot and constantly attacked the various realm eyes of the human world.

Putting aside the Chaos Demon Realm, those secret realms, big and small, are still the same, evolving into the secret realm fluctuations well known to the outside world.

“It’s still different.”

While Lin You was still thinking, Hei Yuan spoke up, "This little fellow doesn't possess some of the characteristics of the secret realm monsters, such as the dueling instinct. If we really want to talk about his nature, perhaps he's closer to a being that I think you're familiar with."

"Teacher, are you saying..."

Lin You paused for a moment and asked in surprise, "Dueling Elf?"

"That's right."

Hei Yuan nodded slightly and said, "This magical cat is like a duel spirit that wanders freely between heaven and earth. However, due to some unknown reason, it has materialized, so even ordinary people can detect its existence."

Without waiting for Lin You to ask, he changed the subject and said, "The materialized magic cat does not possess any combat power, nor can it play any auxiliary role in the battle. However, it is extremely important for one thing, especially for us psychics."

Lin You immediately gave him a questioning look and deliberately did not interrupt.

The atmosphere was silent for a few seconds, and finally, Hei Yuan said loudly:

"The spirit behind!"

Just by chewing on this term, Lin You felt an inexplicable vibration in his heart.

Hei Yuan ignored him and continued to explain, "A back spirit is a unique being formed from pure soul power. Because of this, and because it is highly compatible with the pure soul power of the psychic, the back spirit that is born can rely on the psychic just like a duel spirit."

Lin You listened with great interest, his eyes still gleaming with the desire for knowledge.

Obviously, Hei Yuan knew what he was curious about, and the next moment he said, "Once a psychic has his own backing spirit, the quality and endurance of his spiritual power will undergo a qualitative leap, and even produce some special effects. Just like my master, his spiritual power, with the blessing of the backing spirit, can make the high-star spiritual patterns engraved on the cards become 'toy-like'!"

"Toy-like?"

This time Lin You couldn't help but speak out, and it sounded very special.

“It’s like an independent deck system.”

Hei Yuan quickly explained, "It can be called a toy deck. When the toy-transformed cards attack, they gain a strange toy power. When this toy power accumulates enough, the attacked monster will be transformed into a toy. The toy still looks like the monster itself, though its size will change, usually shrinking. But regardless of whether it grows or shrinks, the enemy who is transformed into a toy will completely lose its combat effectiveness."

"sharp!"

Lin You couldn't help but sigh, "This is like the accumulation of destructive power. Perhaps turning the opponent into a toy requires a large number of attacks, but simply by outlining spiritual patterns on the cards, such a powerful effect can be achieved. The value of these spiritual patterns is likely to increase greatly!"

I couldn't help but think of the strong man in the association who drew the cards for me. Why didn't he have any special effects behind the scenes?

Is it because the level of the card I drew is not high enough?

Although those cards still contain natural seven stars such as Resurrection of the Dead and Ripple Shield-Power of Waves, perhaps the infusion of the spirit behind them requires more advanced cards.

It is said to be a high-star spiritual pattern, but 7-9 stars are all within this range.

Or, level...

Thinking of this, Lin You shook his head violently.

What are you thinking about!

After all, it is the result of someone else's hard work. Even if you paid for it, you get what you pay for. If you can successfully outline it, you have made a profit!

Besides, the person to be compared with is a psychic master of the same level as the Grand Master. Even if they cannot compare, it is normal.

Thinking about this, Lin You couldn't help but ask tentatively: "Teacher, what about the spirit behind you..."

He was halfway through his words when he noticed Hei Yuan's unfriendly look and immediately fell silent. He quickly pretended nothing had happened and changed the subject, "Teacher, you still haven't told me what the purpose of this materialized spirit is."

Also, the name Magic Cat is a bit random, isn’t it?

But Lin You didn't complain about this to his face.

The name is just a symbol, the effect is the king!

As long as the effect is strong enough, what does it matter if he is called a second-rate person?

Hei Yuan snorted lightly and said unhappily, "No need to change the subject. To tell you the truth, your master has indeed not awakened his spirit. But it's not just me who hasn't awakened. Your master hasn't awakened either!"

"puff……"

Lin You laughed secretly. The teacher was so mean. Not only could he not do it himself, but he also had to drag his master down with him.

It’s a pity that I have never met that master and don’t have any contact information.

This means I want to expose the truth, but there is no place to file a lawsuit.

Hei Yuan said calmly, "There's nothing strange about this. The spirit behind it is not an ordinary being. It's similar to the duel spirit. How could it be simple?"

A book friend I've known for ten years recommended Yeguo Reading to me. It's so useful! I use it to pass the time, even while driving or before bed. You can download it at www.yeguoyuedu.com.

"Don't even mention me and your great-grandmaster. Even your great-grandmaster, Elder Wang, had a very difficult time awakening. If we count all the powerful psychics today, there are probably no more than five who can successfully awaken their back spirits at the Grandmaster level!"

"So difficult?"

Lin You was surprised this time, that was the grandmaster level!

Even for him now, she is someone he needs to look up to.

But even with such powerful psychics who can awaken the spirit behind them, the teacher said that there are no more than five people?

If that's the case, Lin You wouldn't be surprised.

Even if the strong man from the association who drew the card for himself is quite powerful, how could he possibly reach this level?

"It's so difficult, but those of us who have made some achievements in spiritual communication still find it difficult to give up this thought. We keep trying and seek help from outside forces to expand our possibilities."

There was suddenly a hint of heaviness and sadness in Heiyuan's tone.

After a moment's silence, he spoke again, "And this magic cat is one answer. It can help the psychic, increasing the possibility of awakening the spirit behind it. According to the law, about every month, the magic cat will briefly awaken for a period of time, which may be as short as a few minutes or as long as a few hours. During this period, the spirit magic array under its feet will be greatly stimulated. At this time, it can absorb your spiritual power and be nourished by it. When it reaches a certain level of nourishment, it may be the moment when the spirit behind it awakens."

Lin You's heart was shocked, and he immediately understood the importance of this magic cat.

This is definitely something that will drive countless psychics crazy!

And this kind of being, who also looks forward to awakening the spirit behind the teacher, is now going to give it to himself?

Lin You immediately shook his head after realizing what was happening. "No, Teacher, this is too expensive. Even if we ignore the price, you are the one who is on the path of a powerful psychic. This is the moment when you need this psychic cat."

"need?"

Hei Yuan suddenly smiled. "Many years ago, when Teacher Fu gave it to me, I think it was with this expectation and thought. However, he was unable to fulfill his wish, and as his disciple, I am powerless to do anything about it."

As he spoke, he looked at Lin You again, his eyes filled with hope. "Now, it's time to let go of what should be let go. With it, I can add some color to the disciple-taking ceremony that I have been putting on hold for a long time. More importantly, there is one thing I am sure of..."

Hei Yuan smiled broadly and said, "My feelings now, at this moment, are different from those of Teacher Fu back then. It's true that Teacher Fu had expectations of me then, but those expectations were tinged with uncertainty and hope. But my feelings for you... are certain. You, Lin You, can definitely achieve the awakening of your soul!"

"Please accept it. I have been waiting for this gift from you."
