When Qi mentioned the word "Secret Potion," both Fugaku and Shisui wore expressions of confusion.

In their understanding, there were indeed drugs in the Shinobi World that could temporarily boost Chakra or physical abilities, such as the military rations pill or the three-colored pills of the Akimichi clan.

However, those things all came at the cost of overdrawing one's life force and had severe side effects.

More importantly, the power of the Sharingan was rooted in spiritual energy and the special Chakra secreted by the brain, which was fundamentally different from mere physical energy.

It was influenced by intense emotional fluctuations and was closely linked to the concentration of one's bloodline; it was a mysterious and profound power.

A secret potion that could increase the Sharingan's awakening rate and Dojutsu?

This was unheard of, and even somewhat defied common sense.

"Secret Potion?" Fugaku's brows furrowed tightly.

As the clan head, he had accessed all the clan's records and had never heard of such a thing.

"Qi, are you sure? The growth of Dojutsu has always relied on talent and stimulation from cruel battles. I have never heard of it being aided by medicine."

Shisui also chimed in, "That's right, Qi. Moreover, any drug that forcibly boosts power must come with huge risks. Our clansmen cannot become test subjects. We cannot walk the evil path of Danzo just for power."

There was a hint of vigilance in his words; having just witnessed Danzo's arm, he held an instinctive resistance to any unnatural power enhancement.

Facing their probing and skeptical gazes, Qi did not explain too much.

He knew that for such a concept that subverted their cognition, any words would seem hollow.

Facts were always the best proof.

"Clan Head, please prepare a strictly confidential laboratory for me, along with some conventional pharmacological equipment and basic medicinal materials. I need a few days."

Qi said calmly, his composure giving the two a shred of confidence.

Although Fugaku was full of doubts, having witnessed Qi's various incredible means, and seeing that arm belonging to Danzo still lying before them, he ultimately chose to trust him.

He nodded heavily and immediately arranged for his trusted aides to handle the matter.

As the number one clan in Konoha, the Uchiha possessed at least this much in terms of resources and execution.

Soon, a heavily guarded secret chamber located deep beneath the Naka Shrine was quickly converted into Qi's exclusive laboratory.

It was isolated from the world, and no one could disturb him.

Qi locked himself inside and sank his mind into the system space.

Focusing his consciousness on the ancient scroll named 【Dojutsu Activation Secret Potion】 in the 【Clan Treasury】, he selected "Redeem" with his thoughts.

【Redeem 【Dojutsu Activation Secret Potion (Incomplete Version)】 complete prescription, requires 1000 Clan Contribution Points. Do you wish to redeem?】

"Yes."

With the confirmation, a massive stream of information instantly flooded into his mind.

Every detail of that ancient prescription, every ratio, and even the processing methods for every medicinal herb, were clearly presented before him.

The prescription consisted of thirty-seven rare medicinal herbs, with three main ingredients at its core: "Dragon Blood Grass" which could powerfully stimulate Chakra meridians, "Moonlight Moss" which contained vast life energy, and "Tranquility Flower" which could soothe the spirit and prevent one from going astray.

Its principle was to use the overbearing medicinal properties of "Dragon Blood Grass" to forcibly impact and widen the eye's Chakra meridians, like a flood scouring a river channel, then use the life energy of "Moonlight Moss" to replenish and repair, and finally use the "Tranquility Flower" to harmonize and prevent mental collapse.

Theoretically, this could indeed greatly promote the growth of Dojutsu.

It was a product typical of the Warring States Period period—simple, crude, and effective.

But right at the end of the prescription information, the system clearly labeled its deadly side effects in scarlet, warning-like font.

【Warning: This prescription is an incomplete version. Its core principle is to savagely overdraw cellular activity, sacrificing potential life force in exchange for a momentary burst of Dojutsu. Long-term use will significantly reduce the user's lifespan and cause irreversible, permanent damage to the body's meridians. Light cases result in chronic illness, while severe cases result in premature death.】

So that was it.

This wasn't nourishment at all; it was drinking poison to quench thirst.

In the Warring States Period era, human life was as cheap as grass.

To survive on the battlefield, such methods of overdrawing the future might be acceptable, but for the Uchiha who sought long-term development, this was no different from digging their own graves.

Facing this dilemma that almost sentenced the prescription to death, Qi was not disappointed; instead, he smiled.

For the Ninjas of this era, this was an unsolvable dead end.

They only knew the medicinal properties of the herbs but did not understand their internal, deeper molecular action principles.

But for Qi, who possessed knowledge of biology and pharmacology from his previous life, this was not a problem at all.

"System, activate the biological sample analysis function and perform a three-dimensional structural analysis of the entire prescription at the molecular level."

【Command received. Analysis starting... Energy consumption in progress...】

As the command was issued, that ancient prescription in his mind was instantly "digitized."

The active ingredients of every medicinal herb were broken down into complex molecular structure models.

How they interacted with each other and how they affected human cells were presented in the most intuitive and precise way.

It was as if he had been given a super-high-magnification microscope, allowing him to look directly at the essence of pharmacological reactions.

His gaze, like the most precise Chakra scalpel, swept rapidly through these complex structural diagrams.

At the same time, he mobilized the knowledge reserve from his previous life to conduct cross-comparisons.

Soon, he keenly pointed out the core of the problem.

"The problem lies here. The active ingredient of this 'Dragon Blood Grass' is too irritating, and it lacks guidance."

Looking at the molecular structure diagram analyzed by the system, he whispered confidently, "The wisdom of the ancients is worthy of respect, but their knowledge had huge blind spots. And I, as it happens, can see those blind spots."

The active ingredient of "Dragon Blood Grass," while activating eye cells, also destroyed the cells' own mitochondria and self-repair mechanisms.

This wasn't nourishment at all; it was predatory extraction!

And the life energy of "Moonlight Moss," although it could replenish, was more like a "painkiller."

It treated the symptoms but not the root cause and could not repair the damaged cellular essence.

Having found the root of the problem, the solution came naturally.

He immediately locked onto several herbs in his memory from his previous life that possessed the effects of "gentle nourishment," "promoting cell regeneration," and "strengthening cell wall toughness."

These herbs also existed in the Shinobi World, but because they lacked direct combat enhancement effects, they were not valued by Ninjas.

He began to drastically improve the original prescription in his mind, like a top-tier pharmacist.

He used the mucus of "Snake Saliva Fruit" to coat the active molecules of "Dragon Blood Grass," forming a sustained-release structure, turning it from a "deadly poison" into a "gently nourishing medicine."

He added powder of "Earth Root Ginseng" to strengthen the toughness of the eye meridians, allowing them to withstand stronger Chakra impacts without rupturing.

Finally, he replaced the mediocre "Tranquility Flower" with pollen from a flower called "Sun Sunflower," because the ingredients of the latter could promote benign cell division and regeneration, fundamentally solving the problem of cellular loss.

After some precise adjustments and ratios, a brand-new, "Perfect-grade" improved prescription was born in his mind.

【Improved Version · Dojutsu Activation Secret Potion (Perfect-grade): Effects increased by 30% on the original basis, side effects completely eliminated.】

Looking at this enticing prompt, Qi nodded with satisfaction.

However, a new problem lay before him.

He had the prescription, but several key medicinal herbs listed on it, such as the core "Dragon Blood Grass," and the newly added "Snake Saliva Fruit" and "Sun Sunflower," were extremely rare varieties.

Within the Uchiha Clan Compound, which were strictly monitored by Konoha, they could not be found at all.
