Ever since Sergei had been captured, Yucheng had kept him trapped in a Sharingan Genjutsu to keep him quiet and obedient.
Yucheng took a scroll from inside his clothes. The formula for Impure World Reincarnation was recorded on it. He unfurled it and placed it on the ground facing Sergei. Then, with a swift stroke of his blade, he cut a section off Chiyo's right arm and placed it in the empty space at the very center of the formula.
The moment the formula on the scroll touched Chiyo's flesh, it seemed to come alive, spreading toward Sergei on its own. Finally, beneath everyone's astonished gazes, a mysterious, eerie pattern formed on the ground, surrounding Sergei at its very center. The sight made their scalps prickle.
Once the preparations were complete, Yucheng looked back at Chiyo and said, "Lady Chiyo, a force might come to take you away in a moment. Don't resist, though resisting wouldn't do much good anyway."
Looking at the formation on the ground, Hu Tao couldn't help asking, "Yucheng, what exactly are you doing? This isn't a method for making zombies, is it?"
Yucheng smiled. "Who told you I was going to turn Chiyo into a zombie? Just watch. This is a ninjutsu worthy of going down in Teyvat's history."
An ominous premonition flashed through Hu Tao's heart. "What will happen to the person in the middle of the formation?"
Yucheng smiled without answering. He crouched down and brought his hands together in a Snake seal. A torrent of chakra surged from his body into the scroll beneath his feet.
[Ninja art: Impure World Reincarnation Jutsu!]
As chakra activated the formation inscribed on the ground, the formation's focal point beneath Shelton suddenly erupted with white light.
At that very moment, the unconscious Sergei abruptly woke up.
