[Time Travel + No System + Male Channel + Decisive Killing Method + No Holy Mother + No CP] I hope readers will like it In that battle, Yuanshi Tianzun led the 13 apostles to fight against the Emperor of the Universe. At the same time, the supreme guards of the 13 apostles were fighting against the Emperor of the Universe. After Yuanshi Tianzun and the 13 apostles defeated each other, Yuanshi Tianzun turned into the Cybertron Fire, providing a steady stream of power to the planet. After cleaning up the battlefield after the war, it was found that almost all the supreme guards of each apostle were wiped out. However, Sai Aotian was lucky. When Sai Aotian was discovered by Tianyuan, his body was seriously damaged. Sai Tianjiao used his own powerful power to build a powerful body for Sai Aotian. However, because the body was not his own body, he began to enter the adaptation stage. So he fell into a dormant state, preparing to wake up after the gas and energy core were completely integrated. Unexpectedly, Li Yao traveled through time and entered these bodies at this time. I hope everyone will be interested in the following story.
