The world was suddenly attacked by alien forces. Sun Yuan, as the leader of the strongest air force, fought fiercely with the alien forces. However, human civilization was completely unable to resist this alien force. In the moment of life and death, martial arts cultivators from other worlds came through the air to fight with the alien forces. One of them was a martial arts cultivator named Tong Shu. The master was seriously injured in the battle with the external battleship. When he was dying, he used the jade of time and space to travel back to the past. In order to save his family and lover, Sun Yuan embarked on the road of martial arts, vowing to surpass Tong Shu's cultivation and become a king of the generation, so that he could travel back to modern times and defeat the alien power!
