My Apprentice Started Cultivating Immortality Around the World

Fifteen years ago, Wu Huan traveled through a parallel world and was bound to an extremely deceptive system. The system stipulates that he must train dozens of powerful people who will change the world and start an era of global immortality! Only then can the system be activated with perfect merit, otherwise the system will turn him into a retard! Fifteen years later, Wu Huan came down the mountain. I found that all the disciples were already standing at the pinnacle of this era! Wu Huan looked up to the sky and sighed: "I've already been pretended by you, why am I still fooling around?"
