In Hitsugaya's heart, he had some preparations.
He just didn't expect that a part of the materials would go out of control in this experiment.
When turning senjutsu chakra into five different attributes and then activating the bodies of the mice, if the attributes were incompatible, the final result was devastating...
The rampaging materials, once out of control, exhibited terrifying behaviors.
Not only did they become frenzied, but strange tissues also randomly grew on their bodies.
For example, some developed a layer of keratin, resembling a biological armor, wrapping the material tightly.
This was relatively normal. However, some mice developed huge tumors on their necks.
As the experiment progressed, these tumors slowly grew into another mouse head identical to the original one.
It looked particularly eerie!
These mutants shared a common characteristic: strong aggressiveness. They would attack not only their own kind trapped with them, but also attack lifeless iron cages.
During the attack, they showed no regard for their own injuries. Such insane and cruel behaviors made Hitsugaya, the observer, quite uncomfortable.
It was too bloody...
But fortunately, besides the five elemental energies, there were Yin and Yang attributes.
Compared to the earlier five attributes, these two were relatively gentler and had not rampaged so far.
Moreover, the activation of these two attributes mainly affected the body and spiritual energy, which was good news for Hitsugaya.
If the following experiments did not yield better results, he would likely choose these two attributes.
The next experiment involved converting his senjutsu chakra into Yin and Yang attributes and combining them, hoping for some unexpected results.
As a transmigrator, Hitsugaya had heard of the concept of Yin and Yang combination numerous times, and now he had the chance to try it. How could he miss this opportunity!
It was simply a matter of wasting some "materials" and his chakra and time. But if he managed to produce some incredible results, wouldn't that be a great gain...
Unfortunately, up until now, there had been no good experimental results.
"Could it be that the synthesis ratio I chose is wrong?"
After numerous tries, Hitsugaya began to doubt his chosen synthesis ratio.
Hitsugaya had referenced the proportion of Yin and Yang in the Tailed Beast Ball from the original series but evidently, this ratio wasn't what he needed.
Although there were no Tailed Beast Ball-like explosions, the experimental results were quite unsatisfactory.
Rampaging, mutations, deformities, and other issues continually surfaced, making Hitsugaya extremely frustrated and almost ready to abandon his attempts.
"Should I try other ratios..."
In addition to experimenting with elemental chakra, Hitsugaya conducted another experiment, which was barely worth mentioning...
That was directly using senjutsu chakra for body activation.
This would skip the conversion process, making these experiments unnecessary. However, such good fortune was not for Hitsugaya~
Considering the behavior of Jūgo in the original series, Hitsugaya wasn't surprised.
That guy would immediately rampage after absorbing natural energy, an uncontrollable state useless to Hitsugaya~
"Hitsugaya! Are you home? There is a mission..."
One day, outside Hitsugaya's courtyard, a member of the Uchiha Police Force in a green vest shouted loudly, evidently there for something important.
It's worth noting that the Uchiha Police Force's uniform was basically indistinguishable from Konoha's Chūnin vest, except for a shoulder emblem for the police force, which was awkwardly stitched onto the underside of the vest...
At this time, inside Hitsugaya's house, in a room specially reserved for "training", three Hitsugayas were sitting cross-legged.
He was in the crucial phase of his training, which was based on three months of repeated experiments on body activation.
He had chosen the repeatedly failed Yin-Yang combination plan.
Driven by an inexplicable stubbornness, he pushed on when others might have given up, spurred by hazy memories from his previous life.
Now, he was using the golden ratio from his previous life as the Yin-Yang proportion~
In his earlier life, the golden ratio was touted as the most perfect ratio in nature, a symbol of beauty. He wondered if it would have any use in this supernatural world...
He had decided to give it a small try with low expectations~
Surprisingly, the results were delightful!
After many confirmations, he began the process of body activation using this ratio~
Although the Yin-Yang combination sounded great, implementing it was complex.
His strong spiritual power and chakra control far exceeded that of ordinary people, but converting to Yin and Yang attributes, mixing them in a certain proportion, and making the new energy flow through his body, while gradually diffusing the energy within, was exhausting.
But this was manageable. Isn't that what shadow clones are for?
If one couldn't do it, just summon more helpers!
Solving these problems one by one, Hitsugaya immediately initiated his plan.
He split into two shadow clones, one responsible for converting to Yin and the other to Yang, while his original body combined these attributes and controlled the energy to circulate through his body, gradually diffusing it throughout.
