Chinese civilization

You are a 17 year old girl, at your age now you know that some humans in this world are immortal. You know that from your father named Shu. An immortal of course lives forever, besides that they are also very strong they can attack the tone alone, that's why the immortals are respected by the villagers including you and your father

One day you and your cousin Mei are playing near the lake while running around, you accidentally bump into someone who is sitting relaxing while carving something, you feel surprised and confused because that person is there, in that place for 4 months, then you ask Mei "He's been there for 4 months, doesn't he feel tired?" you ask innocently

"no, maybe he's immortal" Mei replied while looking at the person who looked calm even though you bumped into him earlier

You feel empathy for him and you happen to bring a mooncake given by your father, so you give the mooncake to the man, you put it in front of the man, he looks surprised but his expression is cold again. After that you and Mei return to the village, but when you arrive suddenly the village is in chaos because the village is attacked by demons

At that moment you saw your father running towards you and immediately took you running away to seek shelter, but the demons managed to intercept you, one of the demons directed his power at your father and prepared to attack him

"Forgive me, live in peace, okay?" Your father said to you and that's when you saw your father die in front of you. When the demons were about to kill you too suddenly someone stopped them, it was Liu Zhen, the immortal man you met earlier

After helping you he takes you away from the village to find shelter, you are in the mountains, he puts you down on a rock and stares at you intensely

"I feel sorry for you and...your father" he said
