After the Invasion of Demons, I Transformed into a Jidao Martial Saint

Humanity is defeated! In the face of foreign enemies, mankind was forced to bend its back for the first time. Under the tyrannical power of the demon, countless soldiers and civilians were killed and injured in the war zone. The mayor led the city to surrender in order to survive, and the superpowers who claimed to be a new human race also turned against them... Everything pointed to the crisis of human destruction. With the establishment of the Daogang Alliance, the crisis of mankind has been alleviated, but the sword of destruction still hangs over its head. Until Lu Jiu traveled through time and killed the mutated mice in his home to gain longevity. Later, he learned that Shouyuan could grow himself, perform martial arts deductions, and travel through the heavens. He couldn't sit still! … The demons are coming, so it's not against the law for him to fight back! Since he fought back, it doesn't matter if he kills him! I've already killed them all, why should I kill more! "Brother Dog, why are you crying? Come on, smile!"
