Gu Yang is a thief, first he picks up small things, then when he gets a little bolder, he picks up cell phones, wallets, batteries, bicycles, watches, and metal jewelry. As long as it was accessible and valuable, there was nothing he wouldn't steal. He thought his life would just go by like this, until one day, he discovered that he had traveled through time and space to another parallel time and space, where he was an immature version of himself sixteen years ago. At that time, he had not yet embarked on the road of no return as a professional pickpocket.
He once imagined that someone would come like a god covered in light and pull him out of the mire, but he didn't wait. So, this time, he wanted to give himself a different ending than in the past. If no one could be his god, then he would be covered in mud and try his best to be his own god.
To sum it up, it is a story about saving yourself.
Purpose: The only one who can save yourself is yourself.
