Uchiha Yū's exposed skin was covered in chakra pathways resembling earthworms. Stimulated by the Hero Water, those pathways began to swell, accompanied by piercing pain throughout his body. This was the most dangerous stage of injecting Hero Water.
It was also the primary reason people died after drinking Hero Water.
"My lord, should we increase the anesthetic dosage?"
Outside, Muichiro Tokito's eyes revealed his tension. Seeing the savage expression on Yū's face, he subconsciously raised his hand, ready to halt the process.
Uchiha Yū slowly opened his eyes and shook his head, stopping him. As the entire vial was injected, the bodily modification reached its final stage.
The pain coursing through Uchiha Yū's body rapidly faded. He could feel the chakra flowing through his chakra pathways becoming increasingly turbulent and powerful.
Hero Water itself provided a certain boost to chakra. The weaker a person was, the more noticeable the enhancement. But for Uchiha Yū, whose chakra reserves had already reached the level of a Tailed Beast, the increase was negligible.
However, the expansion of his chakra pathways was enormously helpful to him. What Uchiha Yū lacked was the speed at which he could output chakra. With the experiment's success, the ninjutsu he could now release were even more powerful!
Almost at the exact moment the experiment ended, a pale purple glow erupted from Uchiha Yū's body.
"Ding! Ding!"
The originally white laboratory suddenly blared alarms because something had exceeded its limits by far. That meant some piece of equipment in the lab had been damaged.
The personnel still conducting experiments abruptly stopped what they were doing and instinctively tried to flee, only to be stopped by Muichiro Tokito. A crazed smile appeared on his face as he loudly announced:
"The Hero Water we developed has worked on my lord!"
