Cheng Huan bound the system when he traveled through time. Complete tasks to gain experience points, and the professional bottleneck is a joke to him. Not only that, he also relied on the system to become a multi-professional master! Atomic bomb magic pattern array, magic crystal cannon, city in the sky... "Have you heard? The God of Death broke into Shuguang Academy yesterday without knocking on the door. He was stunned and slapped twice..." Legions of the dead surged in the pitch-black abyss, and humans who spent the polar night ushered in the shadow of the dragon. After one disaster after another, people discovered that Cheng Huan seemed to be among them.
