Chen Gu has been staying in Wushan for many years. It has been so long that he still remembers his old friend's voice and appearance, and has forgotten too much of the past. Only a green shirt and a handle in his hand remained in his memory. It wasn't until he finally forgot everything in the world that he realized that there was no great path in his life, only regret.
After that, he jumped off Wushan Mountain and never looked back.
How many years had Tiandao waited for the gods in this realm to die?
Intention: It is perfect to have regrets.
