I read a quick transmigration bl system novel in which MC transmigrates to a certain time before the body he's occupies dies.In the Ist arc he occupies a boy who is orpan being raised by his uncle.His inheritance is that of phoenix.he doesn't want anyone to find about his inheritance so acts as he doesn't have the inheritance. The ML is his roommate whose inheritance is dragon i think.i think the ist arc name was the phoenix. I don't remember much because i lost the novel link before i could read further. If anyone knows the novel please tell me. The another novel is something i read before . The ML is a high god connected to the system. And everytime MC ask something from the ML before death regarding next world. It happens . Like he asked the ML to be chef as he was not that much of cook .then in next world he was world class cook.
[The ML is a high god connected to the system. And everytime MC ask something from the ML before death regarding next world. It happens .
