My Father Cheng Yaojin and I Are Competing to See Who Is More Cheating.

Traveling through time and being the son of Cheng Yaojin, Cheng Chumo originally wanted to lie down and be a dandy. Unexpectedly, the system issued a task on the first day: "Ask the host to complete a successful prank on Li Shimin, and the reward is: a mysterious gift package!" Cheng Chumo held his forehead and smiled bitterly, and had no choice but to bite the bullet and sneak into the imperial study room. Unexpectedly, when he had just added special ingredients to Li Shimin's tea cup, he heard a familiar roar behind him: "Little bastard, what are you doing?!" Cheng Chu silently shook his hands and sprinkled the whole bag of pepper into it - and Li Shimin picked up the tea cup with a smile... --- A smoky warm wind mixed with the smell of sandalwood penetrated into his nose. Cheng Chumo opened his eyes suddenly, and his brain throbbed with pain, as if he had been personally cared for by Cheng Yaojin's fist as big as a sand bowl. What comes into view is the intricately carved bed top, the brocade tent hangs low, and the body is covered with a silk quilt that is slippery and feels great to the touch. He turned his neck stiffly and saw the round table of huanghuali wood, the clumsy-shaped porcelain, the huge rhinoceros horn bow hanging on the wall... And the moon-white ancient costume he was wearing, which was made of too good a material. "Hiss——" Fragments of memories that didn't belong to him flooded into his mind, making stars appear in his eyes. Cheng Yaojin... Lu Guogong... Cheng Chumo... During the Zhenguan period... Let me choke you! Time travel master, are you feeling dizzy after working overtime? It's not good to throw me into any crew, why don't I just throw me into Chu Tang Lai? And he became the famous eldest son of the Cheng Yaojin family who was not very smart? ! In his previous life, he was just an ordinary social beast, the kind who died suddenly while working overtime without anyone noticing. In this life, he was directly reincarnated as the son of the prince of the country.
