Shrunk into a Cub of an Old Enemy

Song Linggui suffered a physical breakdown working for the company, and was treated as an abandoned son by his father and sent to marry his old enemy. Before the enemy could torture him, he lost to the disease first. He opened his eyes and was reborn, but he shrank inexplicably and became the estranged son of an old enemy... As the "only son" of Xi Mingchen, a high-ranking and powerful man, he doesn't have to go to work and can sleep until he wakes up naturally. When he frowns, more than a dozen people will greet him. In the last life, Xi Mingchen ignored him after getting married, but in this life, he pretended to be mute. Not only can Meng Gourd talk to himself awkwardly, but he doesn't have to suffer the consequences and call him daddy. Father Xi, who has so many things to do, would leave his job and come back to take care of him and put him to sleep when he was sick. His life was so comfortable that he wished he could be someone's son for the rest of his life. Until one day He saw a file called "Mang Mang's Fattening Diary" lying in "Dad's" hidden folder. The grapes flown from abroad that he was chewing suddenly lost their sweetness. Mangmang is his nickname, and there are only two people in the world who know his nickname - his grandmother who died when he was eight years old, and... Xi Mingchen in the previous life. - Before his rebirth, Song Linggui and Xi Mingchen fought to the death, but in the end the company fell into the hands of his illegitimate brother due to his father's favoritism. In this life, relying on his identity as Young Master Xi, he was attacked by a large number of people who were eager to please him, and the Song family soon fell apart. His father regretted that he spent a lot of money looking for him, his younger brother was kicked out of the house and became a lost dog, and the company was acquired by the Xi family and put in his name... Song Linggui was very satisfied with his revenge, except—— "I am also your property. When can I register it in your name?" I want to coax him to be my son, and I want to have a household registration book with him! Dreaming! "Sorry, Dad, we can't mess around." [A grudge-holding and arrogant person with evil intentions is attacked by VS being pampered by a powerful person] 1. Attacking and receiving are both physically and mentally pure. The son's affairs were caused by attacking and receiving. 2. Double life, 1v1, year on year, he. 3. Shou will not forgive anyone who hurt him in the previous life. 4. The character design is not perfect, the plot is nonsensical, and the writing style is out of touch... You can scold me, but don't scold me. Intention: The world and I love you
