Underworld Students Join the Tang Dynasty

Lin Xuan, who obtained the "underworld" system, traveled through the Tang Dynasty and encountered the Tang Dynasty version of "Liu Guanzhang" of the Three Kingdoms. From then on, he established the most powerful gang in the Tang Dynasty! Pingshanzhai, suppressing the Turks, even Li Shimin would treat him like a brother when he saw him. A gangster wearing a suit appears in the Tang Dynasty and asks you if you are afraid? "Why are you waiting to run away? Although I am a gangster, I am also a thief. I don't harm the people, I don't cheat and kidnap, I just rely on my ability to unify the world!" Li Shimin: "Brother, can you teach me how to govern a country? Tell me, which of my daughters do you like?" Princess Wencheng: "Brother Xuan, aren't you a gangster? Come and kidnap me. I don't want to go to Tubo!" Li Bai: "Brothers are good, and they deserve the title of Immortal. Come, come, let's pair wine with poetry again!" This novel and its characters are purely fictitious.
