Tomb Robber: Blind Man, Don't Run Away!

[Two male protagonists + time travel + CP, please enter with caution! ! This is my first tomb robber fanfic. It may be OOC at times, so I don't like to get into it by mistake. At the beginning, I acted as bait with my little brother, and the tomb I descended was still a Doraemon from the ancient tomb world, but this is not important, the important thing is that I can see the living little brother! Let's just say these are really Thai pants!
