How Did I Pick up Xiao Nanniang and Develop into a Sickly Tyrant?

Li Lin traveled through time and transformed into a street gangster with no money or power. He was incompetent in culture and martial arts and couldn't even make the soap and coarse salt that are standard for time travellers. On a snowy day, he picked up an abandoned child in an alley. She looked like a porcelain doll, wearing an ill-fitting gauze women's dress and shivering from the cold. "Come home with me and I'll take care of your meal." Li Lin wrapped the only tattered cotton jacket he had around the child, thinking: It's just an extra mouth to eat, he can afford it. What he didn't know was that this child's name was Chen Yu. In his previous life, he was an iron-blooded emperor who swept across the world and unified the world. He was decisive in killing and unparalleled in power, and the civil and military officials in the court changed their minds. On the day Li Lin died in his arms, he sacrificed half of the immortal world and returned to where it all began. In this life, he wants Li Lin to live, and he wants Li Lin to belong to him alone. However, Li Lin knew nothing about it at this moment. He was squatting by the stove, worrying over a pot of porridge that was so thin that a person could be seen: "Yu'er, the porridge is thin again today..." Chenyu held the bowl obediently, with an obsession that could not be overcome in two lifetimes hidden in his eyes. He raised the corners of his mouth slightly, and his voice was as soft as cotton candy: "It doesn't matter, I like to eat whatever Brother Lin does." A good-for-nothing time traveler who just wants to support his family, and a young man who pretends to be an emperor. In the fireworks of the market, a story about cultivation, protection and ultimate possession quietly begins. When Li Lin finally discovered that the child who got into his bed every night to keep warm, the way he looked at him was never innocent—— Can he still escape unscathed?
