Xie Chenfan's system told him that he could go back as long as he completed the task, but just when the task was about to be completed, the system ran away.
It was then that he realized that the system was wanted in all planes. The name is Xiao Jiuyuan.
So Xie Chenfan kept doing nothing, collapsing the entire plane and reversing time and space.
"This time, you can't leave me again."
Intention: If you run away and he chases you, we will be unable to fly.
