The Foolish Son-In-Law of the Tang Dynasty

He accidentally traveled to the Zhenguan period of the Tang Dynasty and became Li Shimin's son-in-law. From then on, he lived a comfortable life of beating whoever he wanted. "Is Lu Heng pretending to be a pig to eat the tiger, or is he really stupid?" Li Shimin doubted his life for the nth time. At this time, Fang Xuanling ran to the imperial study and cried without tears: "Your Majesty, your son-in-law Lu Heng beat someone up again! The Qiwang family of the fifth surname is not missing!" Li Shimin covered his forehead: "No one was killed, right?"... At the door of a certain aristocratic family, Lu Heng stood with his hands on his hips and said arrogantly: "Who else! Come out and fight together! My father said that you can't beat people to death, so you can come out without worry!"
