Jiraiya Is Weak? Have You Ever Heard of the Immortal Human Body?

Ke An traveled to a world of high martial arts similar to the Naruto system. When everyone turns 18, they can summon two heirs through the awakening ceremony, but they can only choose one of them to inherit. During Ke An's awakening ceremony, S-class characters Tsunade and C-class characters Jiraiya appeared. He chose C-level Jiraiya as his successor! People were shocked, confused, and puzzled! "Damn! Why did he choose a C-level character instead of an S-level heir?" Faced with doubts, Ke Fang ignored it and practiced with peace of mind. After that, Daxia was surrounded by an endless tide of beasts. When facing the beast god, no one could do anything... Ke An turns on the immortal mode and falls from the sky!
