Didn't I just say it? In my era, no Cultivator truly understood the secret of the Immortal Root.

The Purple-haired girl snorted coldly, then continued, "However, in my era, there was a saying in the top-tier Cultivation World: the Five Elements mutually generate and mutually restrain. Mutation is due to mutual generation, while the simultaneous appearance of multiple mutations is only due to mutual restraint. This leads to multiple mutated Immortal Roots being unable to Foundation Establishment in the same Dantian."

Upon hearing this, Yang Che's heart trembled fiercely.

He already knew that the Five Elements both mutually generate and mutually restrain from the library in Wulong Valley.

But that mutated Immortal Roots were due to the mutual generation of the Five Elements, and that multiple mutated Immortal Roots could not Foundation Establishment in the same Dantian due to mutual restraint, was something he heard for the first time.

The Purple-haired girl continued, "Although no one has truly understood the ultimate mystery of the Immortal Root, the theory of mutual generation and mutual restraint to explain mutated Immortal Roots is currently the most reasonable and has been recognized by countless great Cultivation powerhouses."

Yang Che nodded, deeply agreeing.

At least for him, he finally understood why it was extremely difficult for Mutated Dual Immortal Roots to Foundation Establishment.

In the current Cultivation era, Spiritual Qi is thin, resources are scarce, and the so-called 'Heaven's Grace', which is the Spiritual Milk Pool, probably no longer exists.

And the method of opening a second Dantian for Foundation Establishment should also be like a secret, unknown to others.

However, Yang Che still had some questions, and immediately asked, "Then since I've opened up my Middle Dantian, logically, I should be able to Foundation Establishment now, right?"

"How could it be that easy? Opening a second Dantian only initially solves the problem of your Mutated Dual Immortal Roots mutually restraining during the Foundation Establishment process. Foundation Establishment in Dantians other than the Lower Dantian is extremely difficult. In my era, there was the Spiritual Milk Pool, and the Spiritual Qi was unimaginably vast and pure, directly helping Cultivators lay a good Foundation. Now, it's not easy at all, or even impossible."

Yang Che said, "Then it seems, as you said, I must absorb that Liu Hanyan's poisonous Cultivation to lay a good Foundation for my Middle Dantian, right?"

"That's right. You Cultivate a type of Ancient God Art, which can be used to devour and absorb the Cultivation of that Foundation Establishment Cultivator. Once your Middle Dantian's Foundation is solid, you can use a Foundation Establishment Pill to Foundation Establishment."

"Mm. I understand."

A determined light shot from Yang Che's eyes.

After stabilizing his Qi Refining twelfth-layer peak Cultivation, he exited the stone cave and arrived above the Sea Island.

As soon as Yang Che appeared, Liu Hanyan, who had been guarding this sea area, discovered him.

"Yang Che, prepare to die."

Liu Hanyan immediately activated a Talisman, and the Poison Flood Dragon seemed to have grown another circle larger, madly swallowing towards Yang Che.

It seemed that Liu Hanyan's Cultivation had also slightly improved in this short time!

At the same time, Liu Hanyan did not hesitate at all and directly took out a Talisman Treasure.

"I'll help you block the power of this Talisman Treasure. You use your small Formation to trap her, then forcibly absorb her Cultivation," the Purple-haired girl suddenly said.

Yang Che, who was originally a little uneasy, immediately gained great confidence upon hearing this.

As his Cultivation advanced to the peak of the twelfth layer of Qi Refining, all three hundred sixty Flying Fire Needles could now be controlled.

The Meteor Box danced in front of him, and the three hundred sixty Flying Fire Needles also transformed into an illusory Flood Dragon, fiercely colliding with the Poison Flood Dragon, emitting an earth-shattering roar.

Liu Hanyan discovered that Yang Che's Cultivation had actually Broken Through again, and a hint of anger and venom immediately flashed in her eyes.

She activated the Talisman Treasure without hesitation.

A Flying Sword, wreathed in poisonous smoke, shot towards Yang Che's head like lightning.

However, when this Flying Sword Talisman Treasure was still more than half a zhang away from Yang Che, it suddenly flashed and disappeared, vanishing eerily.

Yang Che's heart immediately filled with joy.

He could sense that Liu Hanyan's Flying Sword Talisman Treasure had been mysteriously absorbed into the Void Illusion Magic Stone Space by the Purple-haired girl.

"Yang Che, this time my loss will require a lot of Ancient God Power to recover. From now on, I won't be able to help you. It's all up to you." The Purple-haired girl's voice was clearly weak.

Yang Che had already driven the three hundred sixty Flying Fire Needles to form the Tai Xuan Hidden Light Formation, surrounding Liu Hanyan, who was still in a daze and disbelief.

The Tai Xuan Hidden Light Formation formed by the three hundred sixty Flying Fire Needles was far more powerful than Yang Che had anticipated.

Liu Hanyan was trapped by the increasingly shrinking Formation of Flying Needles, with mysterious light threads connecting each Flying Needle, a change that somewhat surprised Yang Che.

Seeing that Liu Hanyan, the greatest threat, had been trapped, Yang Che immediately focused his attention on the Poison Flood Dragon.

The Heaven and Earth Chaos Art circulated frantically, and Yang Che fiercely collided with the Poison Flood Dragon, beginning to absorb with all his might.

The Poison Flood Dragon twisted madly, trying to break free, but Yang Che directly used his new power, a Fusion of magical power and Ancient God Power, to cling tightly to the Poison Flood Dragon, making it impossible for it to escape.

Gradually, the Poison Flood Dragon's massive body rapidly shriveled.

Finally, it turned into a flaccid skin, softly falling onto the sea surface.

Then, without hesitation, Yang Che came before the Tai Xuan Hidden Light Formation, slammed his palm onto it, and repeated the process.

Liu Hanyan's eyes were filled with resentment, and she felt a hint of unease, but more than that, confusion.

Suddenly, she realized that her Cultivation was rapidly retreating!

A trace of horror flashed through her mind, and Liu Hanyan's eyes were filled with shock and disbelief.

Her Cultivation was actually being absorbed by this Yang Che?

This discovery immediately made Liu Hanyan feel utterly distraught and beside herself.

"Yang Che, stop quickly, let's make a deal."

Liu Hanyan felt the danger and immediately spoke loudly.

However, Yang Che completely ignored her, circulating the Heaven and Earth Chaos Art almost to its limit.

"Yang Che..."

Half an hour later, Liu Hanyan unwillingly fell onto the sea surface, her heart like dead ash.

Her decades of Cultivation had all been absorbed by Yang Che.

She recalled how she was once a mutated poisonous Immortal Root with extraordinary talent, envied by many Cultivators.

Yang Che also landed on the sea surface, preparing to kill Liu Hanyan without hesitation.

"Yang Che, if you kill me, my Liu Family will never let you go."

Liu Hanyan shrieked hoarsely.

Seeing that Yang Che seemed unmoved, Liu Hanyan anxiously said, "If you let me live, I'll go back to Wulong Valley and help you clear your name from the false accusation of fleeing in fear of punishment."

Upon hearing this, Yang Che stopped his movements.

As his thoughts raced, he had already communicated with the Purple-haired girl in the Void Illusion Magic Stone Space, and then the corners of his mouth involuntarily curled up slightly.

After a moment of silence.

Yang Che said, "Liu Hanyan, back in Wulong Valley, you killed all the Disciples guarding the prison and framed me, forcing me to leave Wulong Valley and come to the Qing Jian Sect in the far east of Jiang Country."

"Even back then, after being poisoned by your green poison, my Cultivation plummeted. Do you know how much hardship I went through during that time?"

"You say you'll help me clear my name, hmph, do you think I care? Those people in Wulong Valley didn't believe me at all back then. From the moment they sided with you, I no longer cared whether I was a Wulong Valley Disciple or not."

Yang Che finished speaking with some sadness, letting out a long sigh.

Liu Hanyan's heart turned cold, and she gritted her teeth, "Yang Che, my Liu Family is the first Cultivation Family affiliated with Wulong Valley. If you kill me, you will undoubtedly face endless retaliation from my Liu Family. I advise you to think it through carefully."

Yang Che's expression gradually calmed down, completely at ease.

Then the Flying Fire Needles directly condensed into a huge sharp cone, piercing Liu Hanyan's glabella without hesitation.

After finding Liu Hanyan's Storage Pouch, Yang Che put it into the Void Illusion Magic Stone Space.

Then he conjured balls of fire, burning Liu Hanyan's corpse to ashes and scattering them into the sea.

The Purple-haired girl said, "Yang Che, the conversation you just had with Liu Hanyan has been etched into the Magic Stone by me. Now that your Middle Dantian's Foundation is stable, you only need to prepare enough Foundation Establishment Pills to start attempting Foundation Establishment."

"How many Foundation Establishment Pills do I need, approximately?" Yang Che asked.

"It's safer to prepare about twenty."

"Twenty?"

A bitter expression appeared on Yang Che's face.

He hadn't expected that in the end, he would still need so many Foundation Establishment Pills.

After thinking for a moment, Yang Che said, "Once I've gathered five thousand-year Spirit Medicine, and finished this inner sea training, I'll return to my former Immortal Cave in Wulong Valley. Perhaps I can gather the medicinal ingredients needed to refine Foundation Establishment Pills."

"Mm. Once you successfully Foundation Establishment, you can begin to fulfill the blood oath we made. I need to recover well during this time, so don't disturb me unless it's important."

The Purple-haired girl said, and soon fell into a deep sleep in the Purple King Pavilion.
