Honkai Impact, please stop thinking about it.

Lin Yu traveled through the pre-collapse civilization and gained strange abilities. The more illnesses he got, the stronger he became.
My childhood sweetheart: "He has a very strong talent. Even if he has vomited blood and is terminally ill, he can still dominate with one sword."
Aponia: "I have never seen such an upright and righteous person. He was so trembling and weak that he couldn't even hold a sword, but he still stood in front of the people and faced the Honkai Beast that was enough to destroy the entire city. "
Kevin: "It's a miracle that he is alive. His existence is the best explanation for Tian's jealousy of Yingcai, and his existence is also the greatest contempt for [Heaven]. The luckiest thing in this life is to bring him into the Chasing Fire." Moths, too, are the most unfortunate.”
su: "I can't heal the world, and I can't heal him."
Phyllis: "If I am the luckiest person in the world, then he is probably the unluckiest person in the world. If he is not weak, he may really be able to save the world."
Lin Yu: "You are here to CPU yourselves! The pain can't kill me, it will only make me stronger."
Eden sniffed and said sadly with tears on his face: "He is right, he is so strong!"
