When I was reading a slice of life ancient theme danmei, I suddenly remember this particular novel but somehow forgot the title Its an ancient theme BL/danmei. I believe its transmigration, if not, then its rebirth but with sort of system interface. The MC came to the host body when he was a child and wake up after fell into a river. The body is a silly child but his family is sooo nice to him. He has a plant ability and and later has a flower in his space to communicate with ML since they were children, who is so far away. MC tells ML that he is a flower spirit and can only communicate after absorbing enough sun/moonlight? The ML is rebirth and staying in a temple. When MC go to the capital to do imperial examination, the apocalypse begin, but I dont remember its zombie or plant mutation... Hopefully I don't get it mixed with other novels More details will be added when I remember hahahaha Edit: I don't know its translated yet or not Edit 2: About the plant ability, I believe that MC has a space where he can plant strange and weird plants (kinda like plants vs zombie things) in there. So is it plant or space ability?? LOL
