Jiang Mianmian time traveled.

Her father had an insidious scholar’s face but a sinister heart.

Her mother had a merciful bodhisattva’s face but a vicious mind.

Her elder brother looked honest but was evil inside.

Her second sister was selfish and foul-mouthed.

They were destined to be villains from birth, to contrast the protagonist’s righteousness, kindness and greatness. They did all kinds of bad things, were covered in filth, fell into an abyss, and came to no good end.

Jiang Mianmian – With the magical spring in hand, weak and timid, she could only let her family live a bit longer…

Disloyal and unrighteous.

No integrity.

But they all lived, with the family intact.

Traveling to the world of Hokage, Kamiyo Colt witnessed the chaos of the Nine Tails firsthand.Without any special powers initially, he planned to develop quietly and survive until the Infinite Tsukuyomi. However, when he first trained his Chakra, his system finally activated.The system's rules were simple:By healing others, he could gain random attributes and skills.“Heal Uzumaki Naruto to receive pure Ashura Chakra!”“Heal Uchiha Shisui to gain his bloodline talent!”“Heal Sasuke Uchiha to obtain pure Indra Chakra!”In this way, Colt steadily developed his abilities over more than ten years.During the Fourth Ninja World War, when the ninja coalition saw him suddenly knock out the Six Paths Madara with a single punch, he looked innocently back at them.“What? I'm a medical ninja. Doesn't it make sense to defeat him with one punch?”
