Dragon Clan: Fujimaru-san is saving the world

Fujimaru Ritsuka, fifteen years old, is the savior.
Reborn again, I have to consider whether this is the only opportunity in this life.
Save humanity, beat Mr. Gai down, and save the doctor!
This time, I will win them all!

ps: It is not an invincible stream, there is no rebirth of Lu Mingfei, the timeline is 2006, but the beginning is directly messy with Herzog's plot.
Guda has not read the original work, but he studied under a British detective and a Chinese military advisor, so I will recommend it now.
A mixed race with a spirit of speech, not a moment.
