MTL - Rebirth of the Super Thief - Chapter 390 :solve

A man reincarnates in the body of a boy who suffered a tragedy, only to realize that he is in the world of My Hero Academia. What's even stranger is that his quirk seems to have the abilities of Nen and Haki.

Kai of the Sorcerer’s Tower is one of the last mages left, barely surviving in a world ruled by creatures of the dark — where the era of mages ended, and most of the lands got contaminated with dead mana. To save his world and fulfil his master’s last wish, he put himself through a forbidden ritual, risking his soul being ripped into pieces to make his way into the past. In an era with abundant mana — an era yet to enter the Golden Era of Magic. Things go wrong, of course, as they always do, and he finds himself thousands of years before the world fell to mana contamination — in the body of a young lord, Arzan. All is not well, though, as the young lord was murdered by someone right at the cusp of a beast wave threatening the territory, while larger threats loom on the horizon. There was a lot to do for Kai to regain his former strength in this time of primitive technology, but then again, he might just be able to change that.

He Xie, a private detective, specializes in investigating extramarital affairs, and once made mistresses and scumbags fearful, he is a good young man with lofty ideals. In the event of an accidental death, you have to start a new life system and complete tasks in exchange for the chance to be reborn.

In “Infernal Affairs”, he worked hard to be a “good person” instead of XXX; in “Youth Bao Qingtian”, he tattooed a sun on his forehead; in “Charlotte Trouble”, Yuan Hua and Qiu Ya sang a plum blossom together, “Lu Xiaofeng” “, “Dragon Babu”, “Kung Fu”, “Bourne Bourne”, “Lord of the Rings”, “Pirates of the Caribbean”…
