Ascended One: Bring a Letter to My Immortal King Father

A serious introduction: Chen Yu, a time traveler, brought his own system to 15,000 years in the future. In order to unlock the system, he recognized the father of a fairy king. Nonsense synopsis: Chen Yu, a time traveler, makes tiger skins into coats, cheating on food, drink, and relationships with his free salary. But no matter how you put it, there are some pitfalls in this system, so it's fine if Mao doesn't use it, and it forces him to contribute to the construction of the motherland. PS: Although this book is about cultivating immortals, it is actually about making complaints. Occasionally, I do some serious things, either pretending to be cool or trying to pick up girls. Hmm... Actually, the original name of this book is "You Cultivation and I will Level Up" or "The Daily Life of Those Who Bring Their Own System" or "The Narcissus Book of the Young Master in the Mountain"
