I Am God: Come and Chop Me Down If You Are a Brother

A huge lightsaber penetrates the blue star, opening a new era, animals mutate, and humans gain life souls. The genius boy Fu Fan was crippled by the system. When he swung his sword a million times, the real system was opened. A Fei taught him patience, waiting, and a fatal blow; Tanjiro taught him to breathe, fight hard and never give up; Sauron taught him penance, sharpness, and the three-sword style; Sasuke taught him Raikiri, Blood Ring Eye, and Susanoo; Ichigo taught him liberation, hollowing out, and the Getsuga Celestial Celestial; ......... As he became stronger and stronger, he discovered that he was actually a god, and the group of brothers he led was trying to kill him.
