Then he regained the Twelve Spacetimes and became the leader of the Twelve Spacetimes Alliance. The whole world trembled because of his words! But after a few years, Ye Chen was tired of this kind of life, and retired from the Twelve Spacetimes and the Demon Realm, no longer intervening in the fight between the two sides. From then on... Ye Chen's legend disappeared in twelve time and space, and everyone thought that the former legend had fallen!

When he was about to plot the ultimate class, he found his former Chinese teacher standing on the podium... At the same time, the demon world also began to prepare to conquer the twelve time and space again.
