Because Mu Ci died young, Ye Jinge, who wanted to save her, was bound to the system and went to each small plane to collect Mu Ci's soul fragments. It wasn't until he came to the plane that he realized that saving people is not easy.
Ye Jinge: "No, I have no chance of winning against the heroine. How can I not save her?"
System: "The host does not support returns once bound."
Purpose: Find you in thousands of worlds and save you
