Xiao Fei was currently walking in his space, checking the growth status of various treasures.
Since the Jianmu world could also cultivate a large number of immortal herbs, ordinary immortal herbs were no longer qualified to enter his space.
Most of the immortal herbs in the space were over a hundred thousand years old.
Beside the Dao Comprehension Spring, a small tree like crystal was growing.
It was the small sapling that had been naturally nurtured before, and it had now grown to over three feet tall.
This small tree was crystal-like throughout, clear and translucent, with each leaf like a work of art.
Xiao Fei had consulted many materials and also asked Xuan Tian Dao Zun and Zhu Yu, but neither of them had heard of such a tree.
Regardless, he felt that this item was definitely extraordinary. He visited it almost every day, eagerly anticipating any changes in the crystal sapling.
However, up to this point, the sapling showed no signs of flowering or bearing fruit.
He gently stroked the trunk and felt his mind become tranquil, a sense of ethereal emptiness washing over him.
After enjoying this feeling for a while, he reluctantly withdrew his palm and walked to other places.
He had planted his Qian Yuan Immortal Fruits and Ginseng Fruits. After many years of growth, the fruit trees had grown a bit larger.
The fruits hanging on the trees were also more numerous than before.
This time, the Ginseng Fruit Tree surprisingly bore eight fruits, all of which had now matured.
Excluding the three Ginseng Fruits promised to Zhu Yu, he would have five left for himself.
Xiao Fei picked all the ripe Qian Yuan Immortal Fruits and Ginseng Fruits, packed them into jade boxes, and sealed them with talismans.
Then he walked towards the Nine Extremes Profound Origin Fruit tree again…
After Zhang Yi's visit to the Jade Void Palace Master this time, he learned that while humanity had the upper hand on the surface of this war, in reality, they were dancing on the edge of a knife.
All thanks to Xiao Fei's contributions, humanity had developed rapidly over the past two thousand years, cultivating a large number of True Immortals and Heavenly Immortals, who were dominating the demon and monster alliance on the battlefield.
However, in these years, only two Immortal Lord powerhouses had been added, one of whom was Zhang Yi himself.
As for powerhouses at the Golden Immortal level, not a single one had been added. Instead, one had died in battle, and several had been severely injured.
It was difficult to cultivate powerhouses above the Immortal Lord realm. Fortunately, humanity possessed a Nine Extremes Profound Origin Fruit, which could increase the chance of a Heavenly Immortal breaking through to Immortal Lord by twenty percent.
Therefore, humanity had accumulated quite a few Immortal Lord powerhouses over the years. Although they were at a disadvantage in the battles against the demon race, they could still barely hold on.
Beyond the Immortal Lord realm, to break through to Golden Immortal, there were no auxiliary resources available; it could only be achieved through one's own comprehension.
Only by comprehending the Great Dao could one successfully break through to the Golden Immortal realm. Otherwise, even if one consumed immortal pills daily like food, it would be useless.
Therefore, there was no hope of cultivating a large number of Golden Immortals in a short period to contend with the demon and monster alliance.
It was only slightly more feasible to cultivate a few more Immortal Lords.
Currently, there was only one Nine Extremes Profound Origin Fruit tree in the entire Immortal Realm, growing on a rock, only three feet tall, and it could only bear one fruit at a time.
It was a supreme treasure of humanity, personally guarded by Xuan Tian Dao Zun. Anyone who harmed even a single leaf would be punished.
The fact that Xiao Fei was able to cut off its root and branches last time was already unprecedented.
Fortunately, Xiao Fei did not waste the precious branches and roots, and successfully cultivated a second Nine Extremes Profound Origin Fruit tree in his space.
After tens of thousands of years of growth, this sapling in the space had grown to be as tall as a person, with lush branches and leaves.
On its first fruiting, it successfully bore three fruits, all of which had now matured.
One fruit could increase the breakthrough chance by twenty percent, so three fruits combined only amounted to sixty percent.
Of course, even without consuming the Nine Extremes Profound Origin Fruit, everyone had a certain chance of breaking through to the Immortal Lord realm.
During this period, the other Immortal Lord added to humanity had broken through through his own strength.
However, among the many Heavenly Immortals in humanity, only he had succeeded, indicating an extremely low probability.
Xiao Fei held these three Nine Extremes Profound Origin Fruits, contemplating how to use them and for whom.
If these three Nine Extremes Profound Origin Fruits were given to one person, the success rate would reach over sixty percent, and most Heavenly Immortals should be able to successfully break through to the Immortal Lord realm.
However, adding one or two more Immortal Lords would not have much impact on the current overall situation.
Xiao Fei pondered, wanting to create an immortal pill that could increase the success rate of breakthroughs.
In the Immortal Realm, no one had truly developed a pill to assist Heavenly Immortals in their breakthroughs over the years.
He wanted to try it now!
He had unique advantages in developing such a pill that no one else possessed.
Firstly, he was arguably one of the most outstanding alchemists in the Immortal Realm.
In terms of alchemy, it wasn't that he had extraordinary talent, but rather that he was highly skilled through practice!
With ample time and numerous spiritual herbs in his space, coupled with several clones.
In terms of the number of times he had refined pills and his experience, he should be second to none.
Secondly, besides his alchemy skills, he also possessed a large quantity of rare materials, which was incomparable to anyone else.
When others occasionally obtained a rare material, they would treasure it immensely, fearing it might drop or melt.
They would hardly dare to use it for experiments; the cost of failure would be unbearable.
But Xiao Fei did not have much psychological pressure in this regard. He had obtained three Nine Extremes Profound Origin Fruits at once.
Moreover, the Nine Extremes Profound Origin Fruit tree had now grown to be as tall as a person, and the next batch of fruits would mature soon.
He could afford to use one or two fruits for experiments.
He had also accumulated many other rare treasures.
At this moment, Xiao Fei took out a Nine Extremes Profound Origin Fruit and cut off a small slice from it.
He then took out a Qian Yuan Immortal Fruit, fifty plants of hundred-thousand-year-old immortal herbs, and dug out some Jianmu root bark from under the Jianmu tree…
These immortal herbs and immortal fruits were not randomly combined. He had carefully considered the medicinal properties and their compatibility for each material.
When medicinal properties interacted and restrained each other, changes would occur, often leading to unexpected results.
Especially since he could decompose and synthesize medicinal ingredients through the Law of Gathering and Scattering.
With his current mastery of this law, he could even combine some other items to generate a new species.
He intended to use these medicinal ingredients for decomposition and formulation to mimic the structural composition of the Nine Extremes Profound Origin Fruit.
This was still very difficult for him, and he wasn't demanding complete replication. As long as it could possess some of the efficacy of the Nine Extremes Profound Origin Fruit, he would be content.
After preparing the medicinal ingredients, Xiao Fei sat down and pondered quietly for a long time.
He wanted to deduce the various reactions and changes of the medicinal properties in his mind dozens or even hundreds of times beforehand.
Only after confirming that he had a thorough understanding of all medicinal reactions did he pick up an immortal herb.
The immortal herb rapidly decomposed into dozens of active ingredients in his hand.
He used a jade bottle to carefully collect a small lump of liquid, only the size of a mung bean, containing only one component needed for this attempt.
The remaining components were casually placed by him in a box for future use.
After extracting this active ingredient, he picked up another immortal fruit and performed the same operation…
