Before them stood a towering mountain wall, forming a circular enclosure.
It was like a crater formed by a massive meteorite impact, with the Ice and Fire Yin Yang Well and the Immortal Herbs nestled within.
But Lin Yu knew this was not caused by a meteorite.
It was formed when two powerful Divine Dragons, who died in a great battle between the beast Divinities and human Divinities in the God Realm, fell here.
The Divine Dragons who died and fell here were the Ice Dragon King and Fire Dragon King, two of the Nine Great Dragon Kings under the Dragon God, the strongest beast Divinity in the God Realm.
It was precisely because the Ice Fire Dragon King fell here that the energy emanating from their bodies, after countless years, eventually formed the Ice and Fire Yin Yang Well, giving rise to these top-grade Immortal Herbs.
"I think what we're looking for is in here," Lin Yu said.
"Brother, protect Lin Yu well, I'll go in first!"
Demon Subduing Title Douluo saw this and charged ahead, easily breaking through the various poison arrays set up by Dugu Bo.
Lin Yu, under Qian Jun's protection, followed closely and also stepped inside.
He finally saw the pond with two colors of spring eyes, ice and fire.
And the Immortal Herbs beside the Ice and Fire Yin Yang Well.
Lin Yu's eyes became incredibly fervent, and he was even more pleasantly surprised: "So many! There are actually so many!"
He saw hundreds of Immortal Herbs, with dozens of them already mature!
He didn't recognize all of these Immortal Herbs, but he had seen at least most of them!
The World's understanding of natural treasures, rare herbs, is very shallow; even a Titled Douluo like Dugu Bo, who held a pile of top-tier Immortal Herb resources, didn't know how to use them.
But there are always some people who will study this kind of knowledge.
For example, Yang Wudi of the Breaking Clan.
And Chrysanthemum Douluo, Yue Guan.
And if one were to say who understood Immortal Herbs the most deeply, it would probably be Chrysanthemum Douluo.
Lin Yu had learned that Chrysanthemum Douluo not only knew about Marvelous Chrysanthemum and Yearning Heartbroken Red but also many more Immortal Herbs.
He wondered at the time how Chrysanthemum Douluo knew this?
Could it be in the Spirit Hall's library?
After all, Spirit Hall has a long history of over ten thousand years and is the place with the richest knowledge resources on the entire Douluo Continent.
So, one day Lin Yu went to the library floor that only Elders could enter.
Sure enough, in a dusty corner, he found a book recording various Immortal Herbs!
Therefore, Lin Yu had already made all preparations before coming.
He discovered that in the Ice and Fire Yin Yang Well, there was an Immortal Herb that was simply tailor-made for him.
This Immortal Herb was named the Seven-Colored Purple Golden Flower.
It possessed the same seven attributes as his Spirit: fire, water, earth, wind, light, darkness, and space; although not the top-tier, it was the most suitable.
Lin Yu unhesitatingly took it and placed it in his spatial spirit tool for separate storage.
The Seven-Colored Purple Golden Flower also has the effect of strengthening the foundation and improving spirit power levels.
He is currently at level 18 spirit power and cannot absorb it now, or it would be too wasteful.
Lin Yu planned to wait until after level 20, so his main goals for this trip were the Octagonal Mysterious Ice Grass and the Fierce Fire Apricot.
These two Immortal Herbs, one is a top-tier fire poison, and the other is a top-tier ice poison.
Absorbing these two Immortal Herbs would surely strengthen Lin Yu's fire and water attributes and allow his body to truly achieve ice and fire immunity!
And be immune to all poisons, while simultaneously enhancing his physique, an effect much stronger than any whale glue!
Undoubtedly, these two are the top-tier Immortal Herbs for improving physique.
However, precisely because they are Immortal Herbs that improve physique, absorbing them will not provide much spirit power increase.
"I've found the resources I want, and now I need to absorb them immediately. Please, two grandpas, wait patiently here!"
"No need to worry!"
Saying that, Lin Yu released his Angel's Wings and flew above the Ice and Fire Yin Yang Well.
"After absorbing the Octagonal Mysterious Ice Grass and Fierce Fire Apricot, my Lin Yu's second spirit ring will be at least four thousand years old or above!!"
"Come on!"
"Octagonal Mysterious Ice!"
"Fierce Fire Apricot!"
Lin Yu's wings spread wide, and ice and fire energy swept out, instantly pulling the two Immortal Herbs in front of him.
And made them collide with each other.
Finally, he swallowed them in one gulp!
"Hmm? My body can briefly withstand their top-tier ice and fire poisons? Forget it, for safety, I must go down and absorb them immediately."
Splash!
Lin Yu plunged into the spring eye in one go.
A long time later.
On the other side.
Dugu Bo was quickly returning to the Ice and Fire Yin Yang Well, accompanied by a girl of about 13 years old.
The girl had short, dark purple hair and looked very spirited, not exquisitely beautiful, but a rare kind of beauty with a demonic charm.
This girl was Dugu Bo's Dugu Yan.
"Grandpa, I feel like if I cultivate here for a few more days, I'll be able to break through to level 26!~" Dugu Yan said happily.
"Oh, haha, is that so? My Dugu Yan is really great!" Dugu Bo said kindly.
The Ice and Fire Yin Yang Well was Dugu Bo's best sacred place for cultivating poison techniques, and it was equally beneficial for Dugu Yan. Therefore, Dugu Bo would often bring Dugu Yan here to cultivate whenever he had time.
But what puzzled Dugu Bo was that his Dugu Yan was a genius with innate spirit power level 8, and she also had the Ice and Fire Yin Yang Well, an excellent sacred place for cultivating poison techniques.
Why was her spirit power only at level 25 at 13 years old?
Dugu Bo himself reached the Titled Douluo realm by relying on the Ice and Fire Yin Yang Well, so he knew how fast one could cultivate poison techniques here.
Logically, with such resources assisting her, his Dugu Yan should have broken through level 30 by now, right?
Dugu Bo even began to suspect whether his Dugu Yan had already been affected by the backlash poison of the Jade Phosphor Serpent Spirit, which caused her cultivation speed to slow down.
"Alas, I, Dugu Bo, have played with poison all my life, yet I am helpless against the poison in my own body, and it even harms my descendants... Yan Yan, Grandpa is sorry!" Dugu Bo sighed in his heart.
Soon, the grandfather and Dugu Yan arrived at the entrance of the Ice and Fire Yin Yang Well.
"Not good! Someone has destroyed my poison array!"
Dugu Bo's expression suddenly changed, and killing intent immediately surged: "Which death-seeking fellow dared to trespass into my Dugu Bo's cultivation ground!"
Dugu Bo, full of momentum, led his Dugu Yan inside.
At this moment, Qian Jun and Demon Subduing Title Douluo were guarding near the Ice and Fire Yin Yang Well, sitting cross-legged with their eyes closed.
They suddenly opened their eyes simultaneously.
"Hmm?"
Because they had already sensed Dugu Bo's arrival.
But Qian Jun and Demon Subduing Title Douluo remained calm, sitting cross-legged, as if only a small fry had arrived.
And to them, Dugu Bo indeed counted as a small fry.
"Brother, that poison-wielding fellow has arrived."
"Brother, since we've met, let's just kill him. Although this Dugu Bo's strength isn't great, he is known in the Spirit Master's world for his unparalleled mastery of poison and his proficiency in group attacks."
"In the future, when our Spirit Hall unifies the Continent, if this Dugu Bo stands with the Empire, he will be no small trouble for us."
