In the cave, Lin Sheng sat cross-legged. As the fine, fragmented blood and qi energy was stripped away, it was forcefully stuffed into his muscles and skin.

In an instant, his extremely thin body immediately gave feedback with a strong sense of greed.

It was like cracked earth, dry for many years, finally welcoming the first rain of its life.

This wisp of pure and concentrated blood and qi energy was immediately completely devoured by his parched body.

"It's useful!?"

Feeling the feedback from his muscles and skin, Lin Sheng's eyes lit up. Clearly, this idea of his was feasible.

Although he didn't know what the final outcome of his act of forcefully merging the great blood and qi circulation with brute force would be.

One thing was certain: it definitely wouldn't be a bad thing.

After all, the blood and qi energy condensed by the great blood and qi circulation originated from himself.

Thinking of this, he closed his eyes and murmured.

"Let me see what changes will occur after I devour all of you?"

With a flicker of thought, he once again stripped away blood and qi energy from the great blood and qi circulation as before, then crushed it and squeezed it into his body.

The blood and qi energy accumulated in his great blood and qi circulation was extremely powerful.

To some extent, the blood and qi energy he condensed was even more abundant than that condensed by geniuses with formidable Bloodline potential.

After all, the Bloodlines between people were actually quite similar.

The reason those geniuses could exhibit formidable Bloodline potential was that the concentration of their main Bloodline within their bodies was far higher than that of miscellaneous blood.

Besides Family Bloodline inheritance, a more crucial point causing this was that their main Bloodline had naturally absorbed a large amount of miscellaneous blood within their bodies from birth.

But he was different. He didn't have a so-called main Bloodline, and the miscellaneous blood in his body had never been absorbed. The complexity of his Bloodline could be said to far exceed that of these Bloodline geniuses.

Under these circumstances, cultivating Heavenly Serpent Bone Exchange would undoubtedly be more difficult, especially the difficulty of the first step, condensing the great blood and qi circulation within the body, which was significantly harder than for those geniuses.

Thus, he was very curious about what kind of reaction would occur after absorbing all the energy from the great blood and qi circulation.

The ancient secret technique, Heavenly Serpent Bone Exchange, had basically deviated from its original path in his hands.

As time passed, he continuously stripped away threads of blood and qi energy from the blood and qi circulation, slowly squeezing and stuffing them into his body.

Due to the overly abundant accumulated blood and qi energy, completely absorbing all of it was not something that could be done quickly.

Time flowed by, and in the blink of an eye, three days had passed.

Water Dragon Mountain, at the mountainside.

"It's been several days now, why hasn't Lin Xiaodi come out yet? Nothing's gone wrong, has it? After all, the Heavenly Serpent Bone Exchange secret technique is extremely dangerous."

Lan Man looked at the deep, dark cave before her and spoke with a hint of worry on her face.

"Tomorrow, if he still doesn't come out by tomorrow, we'll go in and take a look."

Beside her, Qi Ning also frowned and said softly.

Looking at the cave entrance blocked by large rocks, she sighed softly.

After she returned two days ago, she only then heard Lan Man mention that Lin Sheng had actually successfully entered the Heavenly Serpent Bone Exchange, even completing the great blood and qi circulation, and especially that he had even taken the Devouring Heart Pill to aid his cultivation.

After learning of this matter, she could be said to be both shocked and angry.

Originally, after knowing that person's requirement for accepting a disciple, she had already begun preparing to introduce Lin Sheng to other Dark Star Envoys. As for why she gave this secret technique to Lin Sheng, it was just for the sake of going through the motions. She hadn't expected Lin Sheng to actually start cultivating it, not only successfully entering but even reaching the second stage of Skin Transformation.

"This kid..."

Thinking of this, she couldn't help but feel a little regret. If she had known this would happen, she shouldn't have involved that person in the first place. If something really happened to this kid, it would be troublesome.

She was anxious, but she also understood that Lin Sheng was currently in seclusion cultivating and couldn't be easily disturbed, so she could only fret here.

"Okay, tomorrow it is. I hope nothing goes wrong." Hearing this, Lan Man opened her mouth, but didn't say much in the end, nodding in agreement.

"Sister Qi, regarding Tiannan Prefecture here, what arrangements does the Tower have? Are we withdrawing or staying?"

At this point, Lan Man changed the subject and asked.

The current situation in Tiannan Prefecture was completely beyond their control, and whether to leave or stay was something they needed to consider now.

"We haven't received a reply yet, but the message has been sent to several Dark Star Envoys, so there should be a response soon." Qi Ning shook her head slightly and said.

"Dark Star Envoys, huh? That's good. I just don't know which one will come this time. The Imperial Court should also have experts rushing here. If we don't have a strong backer, we won't be able to stay in Tiannan Prefecture."

Hearing this, Lan Man relaxed a bit.

Dark Star Envoys, they were all Divine Transformation Realm experts, absolutely considered top experts in the current era.

Seeing Lan Man relax, Qi Ning showed a slight smile on her face. Just as she was about to say something else, a small black sparrow shot towards her. She reached out and directly grabbed it.

Then she took the letter out from its wing and, after glancing at the content, her expression changed slightly.

"What's wrong? Sister Qi, has something major happened again!?"

Lan Man, who was beside her, saw the shock on Qi Ning's face and quickly asked.

"The people from Ten Thousand Spirits Sect have disappeared."

Qi Ning handed the letter in her hand over and said in a deep voice.

"Disappeared!?" Lan Man quickly took the letter. After reading the content, her brows also furrowed.

"How could that be? Several days have passed. With the strength of Wanjun and the others, they should have already left Tiannan Prefecture by now. Could it be that old fellow Wanjun suddenly changed his mind and took his people to another prefecture? I heard that this Ten Thousand Spirits Sect still has some friends in the Ten Thousand Sects Alliance."

Qi Ning shook her head slightly.

"That shouldn't be the case. The Ten Thousand Sects Alliance is not what it used to be. If Wanjun had a choice, he wouldn't have reluctantly chosen to join Dark Star. So, it's highly probable that something has happened to Wanjun and his people."

"Wanjun's strength is not weak, and he brought the sect's elites, as well as a Divine Transformation Realm Elder. Currently, in Tiannan Prefecture, the Imperial Court only has Lu Chuan. Although Lu Chuan's strength is slightly better than Wanjun's, it's basically impossible to keep them there."

Lan Man frowned and speculated, "Then who could it be?"

"Whoever it is, the strength of the person who acted is definitely very strong, far surpassing Wanjun. Otherwise, it would be impossible for the Ten Thousand Spirits Sect group to disappear without a trace. To be able to do this in Tiannan Prefecture, there is probably only..."

Qi Ning exhaled softly and spoke slowly.

"Sister Qi, are you saying Gongsun Yuanzhou!!"

Lan Man reacted immediately and said, somewhat surprised.

"I'm afraid there's no one else besides Gongsun Yuanzhou..."

"But how did that guy Gongsun Yuanzhou find Wanjun and the others!?"

Lan Man's face showed a look of doubt; she seemed unable to figure it out.

"It's unclear. From the fact that Gongsun Yuanzhou could find the Ten Thousand Spirits Sect's mountain gate, it's possible that there's something on Wanjun and the others that attracted him." Qi Ning also said slowly with a look of doubt on her face.

"Since this Gongsun Yuanzhou could find Wanjun and them, it's possible he might find us!!"

Lan Man seemed to have thought of something and immediately tightened her grip on the black umbrella in her hand.

"There is indeed this possibility. It seems we need to leave here as soon as possible." Qi Ning also thought of this possibility and said solemnly.

"Notify Huang Quan and the others to pack up immediately. We'll leave Water Dragon Mountain first tomorrow."

"Okay." Lan Man nodded immediately and quickly disappeared.

"I hope things don't develop in this direction..." Looking at Lan Man's disappearing back, Qi Ning muttered in a deep voice, then sat at the cave entrance and closed her eyes to regulate her breathing.

The next day, the sky was slightly bright.

Inside the deep, dark cave.

Thump... thump... thump...

Muffled thuds echoed from time to time, their frequency increasing, until finally they sounded like beating drums.

Looking closely, the drumming thuds were coming from the figure sitting cross-legged on the large rock.

The figure was bare-chested, revealing lean and well-defined muscles. As the drumming sounds grew faster, all the sounds gradually converged into a single heavy thud.

Bang—

As the thud fell, a bulge suddenly appeared on Lin Sheng's arm, like a swollen tumor on smooth skin, looking indescribably strange.

And this was just the beginning. Within a few breaths, another muffled thud came from within his body.

This time, a swollen tumor also bulged on the arm on the other side.

Like a chain reaction, the next moment, muffled thuds constantly rang out.

One after another, strange, reddish tumors continuously emerged on Lin Sheng's lean body.

More and more tumors appeared, almost covering his entire body, connecting to each other to form a whole.

At this moment, Lin Sheng looked like a flesh and blood monster covered in dense tumors, making anyone who saw him feel a sense of horror.

These tumors were reddish all over, with raised greenish-black blood vessels and tendons on them, like muscles twisted into a ball, filled with a sense of pure power.

Suddenly, Lin Sheng's tightly closed eyes abruptly opened.

His eyes were bloodshot, and his dark brown pupils held an indescribable longing and madness, like a gambler who had stayed up for several nights without sleep and had almost lost all his fortune, suddenly making a comeback move.

At this moment, within his body, the originally self-contained great blood and qi circulation had completely disappeared. All the refined blood and qi energy had been stuffed into his body.

"Hoo..."

He slowly stood up. His originally lean figure appeared bloated and massive due to the covering of dense tumors.

No, it wasn't just because of the tumor covering; his body shape had also changed.

At this moment, his height had reached just over two meters. This was his natural body shape without incorporating any exotic beasts.

His entire skeleton and muscles were clearly several circles wider and more imposing than before.

It was as if he had transformed from a refugee who couldn't get enough to eat into a bodybuilding champion.

Coupled with the dense tumors all over his body, he looked like a humanoid muscle monster.

"Power... Is this the true power of the human body!?"

Lin Sheng opened his palms and looked at the ugly tumors on his body. He didn't show any sign of disgust or dislike, because at this moment, he truly felt the terrifying power contained within his body.

Nothing was more important to him than the increase in strength.

With a thought, he brought up the System panel and scanned his personal attributes.

【Lin Sheng】

【Realm: Bones Transformation】

【Strength: 12】 【Constitution: 11】 【Agility: 8】 【Perception: 5】 【Spirit: 3】

It should be noted that the current panel attributes represented his pure self-attributes without incorporating any exotic beasts.

Now, his self-attributes on the panel had clearly improved compared to before.

The most significant improvements were in Strength and Constitution attributes.

"Did Strength attribute jump to 12? Constitution also improved greatly."

Before this, he clearly remembered his Strength and Constitution attributes were only seven points.

And now, they had increased by several points at once. In particular, Strength attribute had increased by a full 5 points, and Constitution had also increased significantly, by 4 points.

However, other attributes like Agility did not change.

Even so, with his current body attributes, he had reached an extremely formidable level.

"From the attribute panel, my current physical fitness can already be compared to high-level Spirit Beasts, and may even exceed them."

He murmured to himself, his eyes becoming increasingly bright.

The attribute increase from incorporating exotic beasts from the mountain and sea scroll did not mean that the attributes of those exotic beasts were exactly like that.

He was very clear that the exotic beasts' inherent attributes were much stronger than the attributes gained from incorporating them, but his current attributes were definitely no less than those of high-level Spirit Beasts known for their constitution and strength.

Such an improvement was undeniably significant.

"I didn't expect that after digesting the power of the blood and qi circulation, there would be such a huge improvement."

Lin Sheng heavily exhaled, a smile appearing on his face.

The effect after refining the blood and qi circulation this time was extremely satisfying to him.

At this moment, an unbearable itching sensation continuously came from his skin, or more accurately, from within the tumors.

This itching was extremely intense, so much so that even Lin Sheng couldn't help but frown slightly.

Taking a deep breath, he looked at the tumors on his body. At this moment, the strange tumors were actually vibrating slowly, and the reddish color on the surface gradually became dull.

"This is..."

Lin Sheng narrowed his eyes, already understanding something in his heart.

He reached out his hand, grabbed a tumor on his body, and directly began to tear it off.

Rip—

Amidst the teeth-grinding sound of tearing flesh, a large patch of tumors had already been directly ripped off by him.

These tumors were connected to each other. This tear directly ripped off the tumors from half of his body, and the other side was also quickly torn off by him. The torn-off tumors had now become dull and withered, like scabs that fall off after a wound heals.

As these tumors were torn off in patches, they revealed the strong and solid muscles beneath.

At this moment, his body was still stained with a lot of fresh red blood, but the next moment, his skin pores opened, and in the blink of an eye, he absorbed the bloodstains into his body.

"Is this the true shedding!?"

As all the tumors fell off and the blood was absorbed, Lin Sheng's true appearance was finally revealed at this moment.

Solid, robust, heavy...

These words could all be used to describe his body now.

In contrast, the skin on his strong body was indescribably delicate and smooth, so much so that not even a single pore could be seen, like the finest jade.

Looking at his smooth, fair skin, Lin Sheng furrowed his brow slightly.

Compared to this delicate skin, he still preferred the rough texture from before.

However, this was also good. At least it was much more aesthetically pleasing than the strange appearance covered in tumors.

Although he didn't care about his appearance, it was naturally a good thing not to be so ugly.
