How to Go Back

Wang Zhen was the son of the richest man in a certain province and lived a life of spending money like water. Wang Zhen thought that he would be nothing more than a playboy in the future. He didn't expect that he would be able to time travel. If he did time travel, the system would still be fake. If others go back to the fake system, they must collect enough currency that they recognize before they can go back.
