Hello guys!

I will be very grateful if you could help me out with a manga. The mc is an immortal that meets a tomboyish girl with black hair that resembles someone that the mc knew before. They later discover that the girl is sick and will die if they don't find a cure so they set out to find it. Along the way they meet up with a powerful knight or something. The mc always comes back to life after being killed. A later portion of the manga talks about his past, dinosaurs and monsters (?), dragon (?) daughter, love interest, blind sword rival and magician friends. I also believe it's originally in Korean.

Thanks a lot!

Pretty sure it's Epic of Gilgamesh

Yes yes omg! I don't know how I missed it.

Thank you very much!
