Within the Intercontinental Great Array, which was nearing completion in Zi Tian Oasis.

Tianxie Ziyin was perfecting the Formation while speaking with Yang Che.

"Do you remember that day I sent you to chase Sha Jin? Firstly, I wanted you to quickly figure out the extent of your own strength, and secondly, I didn't want to expose my true power too early."

Yang Che nodded and, with a tacit understanding, handed Tianxie Ziyin a Mid-Grade Spirit Stone.

Tianxie Ziyin skillfully took it, but then suddenly stopped her movements, her expression becoming quite serious: "Yang Che, there are now two difficulties before you."

Yang Che raised an eyebrow, listening attentively with a similarly solemn expression.

Over the past year or so, his Dao of Formation Restriction had finally advanced to a completely new level.

At the same time, he had also learned more secrets about the Cultivation World from Tianxie Ziyin, and his knowledge had greatly increased.

Hearing her say that he was facing two difficulties, he naturally listened very humbly.

"Firstly, your Divine Sense is a bit weak. An Array Symbol Master requires extremely high Divine Sense strength from a Cultivator. To become a truly powerful Array Symbol Master, the stronger the Divine Sense, the better, naturally."

Yang Che nodded, deeply agreeing.

For some reason, his Divine Sense strength had always been his weakness, and he couldn't find a good solution.

Tianxie Ziyin integrated the Mid-Grade Spirit Stone in her hand into a certain part of the Great Array, where it disappeared, and then continued:

"The Cultivation of Divine Sense involves the Soul, and Cultivation Techniques for the Soul have been extremely rare since ancient times. Besides relying on increasing one's own Cultivation to strengthen the Soul and Divine Sense, there are almost no other methods that can singularly enhance Soul strength."

Upon hearing this, Yang Che suddenly thought of the ancient Pill Formula for 'Soul Pill' he had obtained, and immediately asked: "Surely some Medicinal Pills can enhance Soul strength, right?"

"That is natural. However, such Medicinal Pills are like the nine-colored fire lotus that this King seeks; they are something one can encounter but not seek, truly too rare."

When Tianxie Ziyin said this, she suddenly felt a little melancholic.

Thinking of the nine-colored fire lotus, purple fu jade, and hell dark phoenix feather she needed for her recovery, she couldn't help but feel a headache.

Fortunately, from that Boundary Battlefield, Yang Che had found a large amount of purple fu ore for her and, with great mental effort, refined enough 'purple fu jade'.

Although the nine-colored fire lotus had been snatched by someone else, Yang Che had brought back its rhizome. With Profound Rank spiritual mud for cultivation, and then finding an extremely Yang object to assist, it was very possible for the nine-colored fire lotus to re-form its nine-colored lotus seeds.

However, the hell dark phoenix feather was truly too difficult.

Perhaps she could only wait until she recovered fifty percent of her Cultivation before personally searching for it.

While she was sighing with emotion, she heard Yang Che suddenly mention an ancient Pill Formula called 'Soul Pill', so her eyes narrowed, feeling a little incredible.

Seeing her display a rare look of surprise, Yang Che couldn't help but ask, "Zi Yin, is there something wrong with this Pill Formula?"

"There's no major problem with the Pill Formula, just a slight side effect. This is indeed a rare Medicinal Pill that can enhance Soul strength. But are you sure you can find all the medicinal ingredients on it?"

"Most of the medicinal ingredients on it are likely unobtainable, but most can be replaced. However, there is only one replacement for the main ingredient called 'soul fixing grass' that I have not yet found."

Hearing this, Tianxie Ziyin showed a thoughtful expression. After a long while, she solemnly asked, "Are you sure you only lack 'soul fixing grass'?"

Yang Che's Divine Sense entered the Tongyou Medicine Garden in the Magic Stone Space, and after confirming again carefully, he immediately said with certainty: "Indeed, I only lack 'soul fixing grass'."

"Good. This King will order Sha E to use the power of the City Lord's Mansion to search for it. However, if you can successfully refine it then, even if it's a 'pseudo-Soul Pill', remember, you must give this King one first. Only after this King personally tests the efficacy of this Soul Pill will we discuss it further."

Seeing Tianxie Ziyin's solemn expression, Yang Che, though suspicious in his heart, immediately nodded.

He vaguely guessed that perhaps Zi Yin had seen something in this Pill Formula?

"Most likely it's that slight side effect she just mentioned?" Yang Che thought to himself.

After finishing the matter of the 'Soul Pill', seeing Tianxie Ziyin return to perfecting the Formation without speaking further, Yang Che quietly asked, "Zi Yin, what about the second difficulty?"

"Oh, right, there's also the second difficulty."

Tianxie Ziyin said, while simultaneously casting several golden Array Talismans into the Great Array, before continuing:

"The second difficulty is that your Ancient God Art, which is the Heaven and Earth Chaos Art, is incomplete. You yourself know that this ancient Chaos Art scroll only has the Cultivation content for the first three pages, and the rest is blank."

Upon hearing this, Yang Che nodded and said, "That's right, it is indeed so. Since Core Formation, I've gradually realized that the current method of operation for this Chaos Art can no longer keep up with my Cultivation. If not for the ability to utilize the miraculous 'Thunder Fire Refining Hall', I'm afraid this Chaos Art would have reached its limit."

"Do you remember what this King once told you?" Tianxie Ziyin stared at Yang Che, saying seriously.

Yang Che's mind churned, and he quickly remembered: "Of course I remember. You once said that after I reach Core Formation, you would accompany me to the Wanglong Mountain Grotto, and that Stone Cave might not be simple."

Tianxie Ziyin nodded, seeming to feel a hint of relief that Yang Che remembered so clearly.

However, very quickly, she let out a faint sigh, quite helplessly saying: "It's just that I never expected to be teleported from the Boundary Battlefield to this Ancient Remnant Sand Sea, and to find such a Spirit Qi-rich place as 'Jie Tian Peak' in the Purple Heaven Secret Realm. Not to mention that this King will not easily leave again; even if I wanted to leave, returning to the Mist Hidden Realm, how easy would that be?"

Yang Che also couldn't help but think of Old Ancestor Old Man.

So many years had passed; he wondered if Old Ancestor Old Man had safely escaped from that underwater cavern in the river.

Seeing that Yang Che also seemed a bit disheartened, Tianxie Ziyin suddenly said with some reluctance: "You also don't need to be anxious. While you were striving for Core Formation these past years, this King has already gained some clues on how to leave the Ancient Remnant Sand Sea.

When a way to safely leave this place is found in the future, this King will give you a wisp of Clone spiritual sense. You take this Clone spiritual sense to the Stone Cave and release it, and it will be as if this King is personally present."

"Mm."

Yang Che nodded heavily.

Tianxie Ziyin then said, "This Intercontinental Great Array will be completed soon. After it's completed, we'll return to Jie Tian Peak to Cultivate with full effort."

Just as Yang Che was about to speak, he suddenly saw her expression change, her brows slightly furrowed.

While he was wondering, a flash of white light appeared before his eyes, and a cold, black-robed young man with a face full of tattoos appeared; it was Sha E.

"Master, our Zi Tian Oasis is surrounded, and the visitors are hostile."

Sha E's expression was solemn as he respectfully reported to Tianxie Ziyin.

"Can you determine if they are from Sand Sea City?" Tianxie Ziyin asked coldly.

Sha E said: "Uncertain. These people are dressed quite strangely, and their Cultivation is also very peculiar; they don't seem like people from Sand Sea City."

"Indeed peculiar. When this King's Divine Sense spread out, it seemed to be interfered with by something. Something that can interfere with this King's Divine Sense is truly not simple."

Tianxie Ziyin showed a look of surprise on her face, then instructed Sha E: "They should still be some distance from here. You quickly take the Zi Tian Guards. It would be best if you can annihilate them. If not, you must also block them outside the Oasis. After this King's Formation reaches Major Achievement, then let them in."

"Yes."

Sha E took the order and left.

Yang Che pondered for a moment, then said to Tianxie Ziyin: "Zi Yin, I'll go take a look too."

"Good, be careful."

Tianxie Ziyin seemed to say it casually, yet there was no trace of coldness in her voice.

However, as soon as her words left her mouth, both of them were slightly stunned.

Yang Che couldn't help but smile: "Mm. I will be careful."

After speaking, with an indescribable sense of joy, he quickly flew out of Zi Tian Oasis and entered the desert.
