Junior sister, I really need to control you.

The first method is to switch to a cultivation technique called "Burning Cloud Technique".

The name of this technique is quite simple, but it is a top-level inheritance from a major power called "Heavenly Flame Palace".

The power of the Heavenly Flame Palace is even stronger than that of Immortal Emperor Island, but only slightly weaker than the combined power of the four great holy islands.

Such a top-tier inheritance within a powerful force is not something that can be obtained so easily.

Moreover, my junior sister has already made the Taihuang Scripture her main cultivation technique, and the Burning Cloud Technique can only be cultivated as a main technique and not as a secondary technique, so this path is basically blocked.

The second method made Li Yinsheng frown repeatedly.

In the land of the East Sea, there is an extremely rare demon race called "Mermaids". They possess both the cultivation talent and adaptability of humans, as well as the long lifespan and powerful physique of demons. They can even simultaneously use the innate supernatural powers of demons and the magical treasures and spiritual artifacts of humans, making them truly unique.

The second method deduced by the small world is to kill a mermaid immortal above the seventh realm, take its inner core, and help fuse with the Samadhi Fire.

This method requires the inner core of a mermaid or demon immortal; it cannot be replaced with the inner core of any other demon race.

Because the cultivation path of the Merfolk combines the advantages of both human and demon races, the demon cores they cultivate are also quite different from those of other demon races.

For Li Yinsheng, this method was quite stimulating.

Although with his current strength, setting up an ambush to kill a seventh-realm demon immortal would be a piece of cake, and the opponent would have no power to resist, the power of the merfolk is not ordinary.

Among them, there is more than one powerful being of the celestial level.

If we kill a mermaid immortal above the seventh realm, it will inevitably attract the earth immortals of its clan.

If the incident involving the mermaid immortals escalates further, it might attract the true powerhouses of the mermaid race.

This matter is far too risky.

But the third method gave Li Yinsheng an even bigger headache.

To eliminate the danger of fusing Samadhi Fire, all you need to do is mix it with a drop of Three Lights Divine Water.

However, only a powerful being at the Celestial Immortal realm can condense the Three Lights Divine Water using corresponding great supernatural powers. A single drop can restore a near-death peak-level Human Immortal to full strength.

Li Yinsheng asked Xiao Shijie to help him deduce where he could obtain the Three Lights Divine Water.

As a result, perhaps due to the intervention of a powerful celestial being, the small world not only endured unprecedented pressure, but the time required for deduction also reached an absurd 2,700 years.

Even after he finished his seclusion, this deduction would still take more than two thousand years.

This was after he had condensed two more star maps from the Heavenly Jade Disc during his seclusion, further advancing the small world. Otherwise, he doubted that the time would have exceeded three thousand years.

Since none of the three methods offered by Dongtian were reliable, Li Yinsheng had no choice but to put the matter aside for the time being.

To his surprise, after the Stone Fire was perfected, his junior sister refined her first quasi-spiritual treasure in just eight months.

Along with receiving the reward of another eight hundred years of cultivation, and completing another constellation map, he only had a little over a thousand years left to deduce the future.

This was beyond his expectations; he had thought that his junior sister would only have this ability after fusing with the Samadhi Fire.

In retrospect, he had underestimated his junior sister's talent in weapon crafting.

Of course, there should also be a reason, because he invited the three immortals on Polaris Island who were most skilled in weapon crafting to teach his junior sister.

After all, he is now the patriarch of Polaris Island, so he still has some power.

When he first became the patriarch of Polaris Island, he arranged for several cultivators on Polaris Island who were proficient in ancient cultivation scripts to teach him ancient cultivation scripts in their spare time.

As for her junior sister, with three immortals above the seventh realm taking turns guiding her in weapon crafting, she naturally made rapid progress as well.

On the contrary, Li Yinsheng himself, although he has been making progress in learning ancient scripts, is not doing so quickly.

But he can't be blamed for this. The monks who taught him the ancient script had conflicting interpretations, each with their own understanding.

In most respects, they reached a consensus, but in a few places, each had their own understanding and insisted to Li Yinsheng that they were right.

Only then did Li Yinsheng realize that because the ancient texts were so ancient, a great deal of them had been lost, and they were also extremely complex, even the translations could be divided into several schools.

Moreover, since the transmission of ancient cultivation methods is based on spirit worship and does not rely on specific written texts, studying ancient cultivation texts is not even necessary for following the path of ancient cultivation.

People who like this kind of thing are either genuinely interested or just have nothing better to do.

That's why Mu Xiaoyu didn't know how to share the Taihuang Scripture with him before.

After the Ancient Peach Sacrifice Spirit was passed on to her, she knew exactly how to cultivate the Primordial Desolation Scripture.

But when it comes to conveying it in a way that people today can understand, she can only scratch her head.

Li Yinsheng had to organize the differing teaching materials from several teachers halfway through his studies, and then deliberate on his own, making the learning process quite painful.

He couldn't help but wonder how Aunt Qin had become so proficient in ancient scripts. Was it simply because of her family's scholarly background?

During this period, in addition to his studies, Li Yinsheng also helped Polaris Island refine more than thirty special Nebula Pills.

At his current cultivation level, aside from a few extremely special elixirs, most pills only take him one or two days to refine. Moreover, refining over thirty Nebula Pills has also brought him considerable gains—

Each Nebula Pill would attract a pill tribulation during its formation, and after more than fifty repeated lightning temperings, he collected quite a lot of pill lightning in the small world.

The Danlei in the small world has now grown to a considerable size.

Therefore, before all the materials were gathered on Polaris Island, Li Yinsheng decided to refine the pill he had been longing for.

A pill that allows one to take form upon contact with the Thunder Tempering Elixir Technique and engage in combat with others.

The main materials were the Nine Hell Ganoderma he had specially preserved, and the withered branch he had obtained from the Star-Picking Palace that had a similar but much stronger aura to the Nine Hell Ganoderma.

He also took the withered branch and asked Fellow Daoist Shen and several other Earth Immortals on Polaris Island, but no one recognized it.

He couldn't help but wonder whose opportunity that person from the Star-Picking Palace had intercepted, that they possessed something even a half-step Celestial Immortal wouldn't recognize.

Although I don't know its origin or understand its medicinal properties, since this elixir isn't meant to be ingested, adding this withered branch won't hurt.

As long as the final refined pills are powerful enough, that's fine.

After issuing an order to clear the surrounding area and prevent any unauthorized cultivators from approaching, Li Yinsheng began refining the product.

The medicinal materials he used this time were all of a type with a strong but malevolent aura, extremely corrosive or destructive, and normally almost impossible to use as medicine.

Some of them were his own, while many others were taken from the inventory on Polaris Island or collected from elsewhere.

Li Yinsheng felt a bit emotional; being the patriarch of a powerful force could indeed be quite satisfying at times.

While top-tier resources still require personal searching, most valuable assets are much easier to acquire.

He refined these ferocious and grotesque precious medicines and spiritual herbs one by one and put them into the Black Demon Cauldron.

As the Nine Hell Ganoderma lucidum was refined and added into the pot, the pitch-black liquid even began to actively impact the inner wall of the Black Demon Cauldron, showing a strong tendency to violently break out of the cauldron.

However, the Black Demon Cauldron itself also contained demonic energy, and when provoked in this way, it retaliated and suppressed it without any hesitation.

Li Yinsheng showed no intention of stopping it; instead, he watched the scene with amusement.

The Black Demon Cauldron itself is not a demonic treasure; the demonic energy within it is tainted, so when used, this demonic energy has no positive effect whatsoever.

He had considered removing the demonic energy, but it had seeped in too deeply and was almost one with the Black Demon Cauldron. Although the Water Official's ability to dispel evil could suppress and remove the demonic energy, it would also damage the Black Demon Cauldron.

Therefore, Li Yinsheng had no choice but to leave the demonic energy inside for the time being. In any case, as long as it was properly suppressed, the demonic energy would not affect his alchemy.

Unexpectedly, under the fierce provocation of the medicinal liquid, some of the demonic energy actually surged out on its own, beginning to fight against the menacing black medicinal liquid. Seeing this opportunity, Li Yinsheng simply refined the withered branch as well and threw it in.

After being refined, the withered branch did not turn into liquid; it simply shrank considerably, becoming as smooth and hard as obsidian, about three inches in size.

Once inside, almost instantly, the pitch-black medicinal liquid containing the Nine Hells Herb was completely absorbed, leaving Li Yinsheng somewhat astonished.

After all, this time he wasn't refining pills for consumption, and there wasn't even a pill formula; it was just a complete mess. So he had no idea what would happen.

But to his astonishment, the withered black branch that had absorbed the other medicinal liquids began to twist and grow.

Instead of growing taller, black threads began to intertwine and sprout from the withered branches.

It was as if this withered branch was actually a skeleton, now about to grow flesh and blood again.

In a short while, the withered branch transformed into a flying yaksha with wings on its ribs and a completely black body inside the Black Demon Cauldron.

The demonic energy within the Black Demon Cauldron seemed to have been greatly provoked. Although it did not take human form like the Flying Yaksha, it extended countless tentacles formed from purplish-black demonic energy, sweeping towards the Flying Yaksha.

The flying yaksha was entirely black except for its blood-red eyes. It stretched its claws into its chest cavity, pulled out two ribs to turn into weapons, and cut off the tentacles that reached out one by one, swallowing them into its belly.

Li Yinsheng remained silent for a while, then took out a bag of melon seeds, sat down in front of the cauldron, and watched the two fight fiercely inside the Black Demon Cauldron.
