In the Fate of the Country, a Terminally Ill Brother Turns into a Yandere with Gray Hair

[National luck + imagination + transformation + single female protagonist + daily life + yandere] "Chu Yan, I have nowhere to go, can you... Take me in?" Late at night, Chu Yan opened the door and saw not Lin Xuan, his former martial arts genius, but Lin Wan, a sickly and beautiful girl wearing a wide sweatshirt and a face as pale as paper.

Just when Lin Wan thought that she was a burden, and even wanted to "sacrifice" herself with red eyes at night to repay her kindness, [National Destiny Survival] came, and the two of them were forcibly bound and thrown into the abyss and forbidden area!

However, the style of painting in the forbidden area gradually became outrageous. Chu Yan was so frightened that he stumbled while walking, and the kicked stones triggered a chain of mechanisms, burying the Abyss Demonic Dragon alive! Chu Yan sneezed, and sparks fell, directly burning through the Spider Queen's century-old nest! Bite! Congratulations to the Dragon Kingdom players for killing S-level monsters and manifesting top-level spiritual veins and pure yang rain ten thousand times! Players from all over the world collapsed: "Report! He slipped and our team was wiped out?" The whole country of Dragon Kingdom was excited: "Others are here to survive, but this guy is here to buy goods?!" In the tent, Lin Wan, who had regained vitality after drinking the national luck elixir, pulled Chu Yan's clothes with slightly red cheeks: "Brother Yan, except for myself, I can no longer repay you..."
