Ice and Fire Yin-Yang Well

Hearing Yu Tianchen's words.

Dugu Bo, who had still been waiting for him to reveal the remaining two methods, was immediately left speechless.

"Heh, you little rascal."

Dugu Bo chuckled softly and said:

"Very well. Since I've already agreed to help you, I won't go back on my word."

"But you have to promise me that the method you provide will definitely work."

"It'll definitely work. I can swear on my Martial Soul."

Yu Tianchen spoke with a very serious expression.

Dugu Bo nodded.

Swearing on one's Martial Soul wasn't something one could do lightly.

Since Yu Tianchen dared to swear on his Martial Soul, that meant he really wasn't lying.

"In that case, come with me."

Dugu Bo rose to his feet and looked toward Yu Yuanzhen.

"Old Dragon, are you coming?"

"Of course."

Yu Yuanzhen answered without the slightest hesitation:

"I wouldn't feel at ease leaving Xiao Chen alone with you."

"Hmph. Judging a gentleman by a scoundrel's standards."

Dugu Bo snorted and paid Yu Yuanzhen no further heed. His entire body turned into a streak of dark green light and vanished into the air.

Seeing this, Yu Yuanzhen also stood up and came over to Yu Tianchen.

"Xiao Chen, hold on tight."

"We're about to set off."

"All right."

Yu Tianchen nodded.

Yu Yuanzhen then grabbed Yu Tianchen by the shoulder with one hand and rose into the air, following in the direction Dugu Bo had gone.

Sunset Forest, central region.

After flying for a while, the three arrived at the edge of a bowl-shaped depression in the mountains.

"This is the treasure trove you mentioned."

Dugu Bo stood with his hands behind his back and glanced at Yu Tianchen.

"Since you know this place, I imagine I don't need to remind you what to watch out for."

"Of course."

Yu Tianchen smiled and nodded.

"Would you like me to tell you the other two methods now?"

"We'll talk once we're down there."

Since they had already arrived, Dugu Bo could wait a little longer.

"Old Dragon, make sure you keep this kid safe. He may be able to talk about this place as if he knows it inside and out..."

"But this place isn't somewhere an ordinary person can enter."

"If anything happens, don't blame me!"

With that, Dugu Bo didn't look back at the two of them, leaping straight down into the valley.

"Hmph. You think you need to remind me to protect my precious grandson, you old poison freak?"

Yu Yuanzhen snorted. He circulated his powerful Soul Power, shielding Yu Tianchen with a layer of protection as they flew down together.

Once they reached the valley, Yu Tianchen immediately spotted the oval pool at its center.

The water was milk-white on one side and vermilion on the other, the two colors clearly divided, neither encroaching upon the other.

Around the pool, all kinds of plants grew in countless forms, making it seem like a paradise of vegetation.

This was Douluo Continent's must-eat list!

The Ice and Fire Yin-Yang Well!

Looking at the Immortal Herbs, Yu Tianchen could barely keep the corners of his mouth from curling up.

Although he didn't know how to use most of the Immortal Herbs here, that didn't matter.

He happened to know how to use several of the most important ones.

The Octagonal Mysterious Ice Grass and Infernal Delicate Apricot, which Tang San had used to refine his body with ice and fire, and the Full Moon Wearing Autumn Dew, which could enhance spiritual power, were just what he needed right now.

He planned to use the former to see whether he could break through his Great Sun Thunder Body by refining his body with ice and fire, and reach the second stage: the Jade Thunder Body.

The latter was preparation for absorbing a Ten Thousand Year third Soul Ring.

To absorb a Soul Ring of ten thousand years, one needed not only a body strong enough to endure it, but also the ability to withstand the mental shock of a Ten Thousand Year Soul Ring.

So, long before arriving at the Ice and Fire Yin-Yang Well, Yu Tianchen had already made preliminary plans and preparations for the Immortal Herbs he would take.

As for the other Immortal Herbs around him, as well as the rare plants that weren't Immortal Herbs but were still top-grade medicinal ingredients, Yu Tianchen truly didn't know how to use them.

But someone else did!

In almost two years, it would be time for Tang San to awaken his Soul Power.

If Yu Tianchen remembered correctly, Tang San's Mysterious Heaven Skill had hit a bottleneck three months before his Soul Power awakening, and he'd been unable to make any further progress.

In other words, three months before his Soul Power awakening, he would reach level ten!

At level ten, one entered the ranks of Soul Masters.

And becoming a Soul Master meant he'd meet the requirements for a sacrifice!

Yu Tianchen still had three chances to sacrifice. When he broke through to Soul Elder, the system would grant him more random sacrifice chances. Two years from now, it was hard to say whether he'd reach Soul King, but Soul Ancestor was practically guaranteed.

Yu Tianchen estimated that by the time he could sacrifice Tang San, as long as his luck wasn't terrible, he should have accumulated more than ten chances.

He refused to believe that with more than ten sacrifice chances, he still wouldn't draw Tang San's knowledge of Immortal Herbs.

He'd squeeze him dry when the time came!

While Yu Tianchen's imagination ran wild, Dugu Bo finished a quick inspection of the surrounding area. After confirming that no Soul Beasts had entered, he walked over to the two of them.

"Hey, Tianchen."

Dugu Bo spoke up:

"Can you tell me the other two methods now?"

"Hmm? Of course."

Yu Tianchen came back from his daydream and smiled, then explained the remaining two methods to Dugu Bo.

The other two of the three methods he'd offered Dugu Bo had both been devised by combining his own research.

The first was the method Tang San had used for Dugu Bo in the original story. It was relatively reliable.

But ideally, the Soul Bone would be older—or Dugu Bo would have an External Soul Bone like the Eight Spider Lances.

Otherwise, no one could guarantee that a Soul Bone didn't have a limit to how much it could withstand.

As for the second method, Yu Tianchen would use the power of heavenly thunder to temper Dugu Bo's body while cleansing the poison inside him.

In truth, this depended on luck.

Heavenly thunder was supremely fierce and yang. After activating the Five Thunder Shock Drums to their limit, Yu Tianchen could even control lightning that became Ultimate Lightning, which naturally suppressed anything sinister.

Using heavenly thunder to cleanse Dugu Bo's body would lead to one of two outcomes: either Dugu Bo's body would be strengthened so it could withstand the poison within him, or the poison stored in his body would melt like butter, curing him but leaving all his poison cultivation for naught.

As for the third method, honestly speaking, it was an idea Yu Tianchen had come up with by adapting the method of forcing poison into a Soul Bone. He'd never tested it.

He would have Dugu Bo use Soul Power to create something like a Storage Soul Tool, force all the poison in his body into it, and make a Soul Tool similar to a magical artifact.

That way, Dugu Bo wouldn't have to suffer the torment of the poison, and could use the Soul Tool to assist him in coordinated combat.

Unfortunately, during this period in the first Douluo era, the methods for making Soul Tools had long since been lost. To get blueprints for them, they would probably have to leave the continent and seek out the Sun Moon Continent, wherever it happened to be tucked away.
