Zuo Du dreamed of that person again. The experiment failed and he was leaving. After waking up, he found that he had entered a different world and could only leave by collecting all the earth fragments.
In another world, Zuo Du met a man named Fang Yan who looked very similar to the man in his dream.
Zuo Du liked to pester Fang Yan shamelessly. He would look to Fang Yan when he was scared, look to Fang Yan when he was happy, and look to Fang Yan when he was sad. In short, you can come to Fang Yan no matter what.
Fang Yan was a pure egoist, until he met Zuo Du, he made more and more losing trades.
After gathering the earth fragments, Zuo Du discovered that he and Fang Yan had known each other a long time ago, and... Neither of them belonged to this world.
Just making it up, don't take it seriously! ! !
