My name is Feng Xin, and I have been wandering outside the timeline because I was cheated by my father. It was rare for me, who should have lived in legends or turned into ashes long ago, to enter this life. Later, I wished to kill the self who was so curious about the human world. ——Teacher, I am a killer, not a chef. ——Uncle, I am a student, not a babysitter. ——The killer will have no money? If you don't have money, you can take a walk. ——I saved the world and gave up the people closest to me. I don't want to lose you again. ——Congratulations, you lost your girlfriend. (I tried my best on the copywriting) My daughter, there is nothing wrong with doting on her. I personally like HE, so there will be a heroine Mary Sue plot, and I don't like the upper right corner or the lower right corner. Warning: I still don't know what the heroine's character is, but getting something for nothing and waiting to die with a young lady as a companion is the ultimate goal. Mainline FGO, the abilities are borrowed from "Under One Person", the rest only appear in memories or only exist in dialogues. The stupid author is only responsible for opening up the imagination. Thank you for pointing out typos and bugs. Xianyu will try his best to make it smooth. There is no BL plot. Only romance heroes and other non-original characters will be OOC. Forgive me.
