Save the World by Dressing up as a Peach Tree

[Dual male protagonists + double cleansing + he + growth + past and present life + high temperature natural disasters] Sunshine, dark and clingy emperor x peach tree with innocent heart and common people Chu Hai traveled through time and became a peach tree in the world. As a wise tree that witnessed the opening of heaven and earth, he patted his chest and decided: I cover this world. Who would have thought that when the world was created, a gap was left, and a bunch of demons crawled inside. Chu Hai worked hard to finally seal them. He breathed a sigh of relief, closed his eyes, and fell asleep. When he woke up from his deep sleep, there was a severe drought in Kyushu, and not a drop of rain fell in three years. The seal is loose, and the demon is ready to move underground. Chu Hai looked at all this: Forgive me for being young and deciding too early. With the idea of being able to drag one by one, Chu Hai slapped his head: "No, I can't do it by myself. I can't lead a team and can only do it by myself until death. I have to find someone to share the burden, right, my king?" Chu Hai: Star Eyes Xuandu: "..." As a result, after experiencing a series of things, Xuandu discovered, eh, did he actually know Chu Hai tens of thousands of years ago? Did he actually talk about a snake? !
