What was more alarming was that many living organisms originate from ancient ancestors, and most of their genetic information exists in a degenerated or hidden state. This isn't limited to humans. Even if these traits don't manifest directly, it doesn't mean they aren't there.
The Panacea (Universal Serum) cannot distinguish between recessive and dominant genes. As long as the dosage is sufficient, a single injection will activate everything simultaneously. From the perspective of Hiruko's recent R&D, the situation had become increasingly thorny..
The risks associated with this serum were far greater than he had originally imagined. It was absolutely not something to be used casually. Even a small nick on the skin, if treated with a drop of Panacea, could result in weird skeletal protrusions or patches of coarse ancestral fur once the wound healed.
Yet, Hiruko hadn't encountered this issue during his human clinical trials. Back when he was experimenting on insects, large-scale atavism had already occurred, but he hadn't paid it much mind. He had loathed arthropods in his previous life, and in this life, he only tolerated them for research. To him, an ugly bug becoming "uglier" through mutation was hardly noticeable—they were already abstract enough.
As he observed the mutated experimental species, most had "no-go" levels of deformity. The little things are truly "cute" as hell, he thought sardonically. Unless there was a fundamental shift in their genus, he tended to ignore whether a beetle looked "normal" or not. Furthermore, insects have rapid mutation rates and far less complex genomes than higher mammals; they simply lacked the "hidden baggage" that humans carried.
It wasn't until his hidden laboratory annex was overflowing with twitching, multi-limbed monstrosities that Hiruko realized something was fundamentally wrong.
Why, he wondered, did hundreds of human trials show no mutation, while every other animal completely warped?
Hiruko extracted a bit of chakra, letting the pale energy coat his palm. He started to laugh. He had fallen victim to the "darkness under the lamp"—the most obvious answer was right in front of him.
The key was Chakra. This universal energy, guided by the spirit, can derive ten thousand forms. He had subconsciously forgotten that Chakra is a fusion of physical energy and spiritual consciousness. It acts as a corrective map for the body.
Chakra attributes often reflect a person's temperament:
Lightning: Stimulates cell activation (Kakashi, Ay, Sasuke).Fire: Linked to intense desires and restlessness (Madara, Jiraiya).Earth: Provides stability and tenacity (Stone Shinobi).Wind: Grants flexibility and a sharp, cutting edge (Asuma, Danzo).
Chakra acts as a universal bridge to the soul, preventing the body from drifting away from its "intended" form. It effectively suppressed the atavistic chaos of the Panacea.
However, the samples in his petri dishes—grown from blood or hair with low vitality—lacked strong spiritual guidance. Without enough Chakra to act as a "stabilizer," the Panacea ran wild.
Looking at the samples from Uchiha and Hyuga cells, they remained largely humanoid. But the samples mixed with aquatic tissues grew scales, and another sample split its forehead to reveal a third eye.
This suggested a massive secret hidden in the history of human genetics. If the Uchiha and Hyuga traits were first-generation lineages, why were commoners showing such bizarre atavistic potential? Was humanity even native to this planet?
Are the Otsutsuki "ranchers"? Hiruko wondered. Did they seed this planet with humans millions of years before Kaguya arrived to turn it into a Life Planet? Or is it something else?
He rubbed his temples and sealed the research samples behind high-level barrier seals. If anyone tried to force them open, the Curse Seals would incinerate the biological data instantly.
He checked the time. Tonight, Lady Chiyo would be bringing Maki and Rasa's young daughter, Temari, to visit Pakura. Hiruko decided it was time to play "dress up" with his favorite "living doll."
What kind of outfit should I pick for Pakura to wear for her guests?
