There Is a Big Boss in Chang'an

Chen Yan traveled through time, dressed as a death row prisoner, and knelt down waiting to be beheaded. At the critical moment, a voice sounded in my head: "Don't panic, I have died seven times, so I have experience." This voice called itself "Silence" and was one of the first time travellers. It was attacked and killed by those who came after it. It was closest to Chen Yan before it died, so it lived in his mind. From then on, Chen Yan lived a life of "using his body and using his brain for others". Silently said: Then I will tell you what so-and-so is thinking in his heart. Shen Mo said: That guy named Li Shimin, even though he keeps a straight face every day, he actually has a lot of tricks on his mind. Shen Mo said: I know how to make paper, make medicine, and make gunpowder. If you do as I say, I will guarantee that you will become the Prince Consort in three years. Chen Yan believed it. Then he discovered—— Shen Mo is a scroll king. He almost exploded the Tang Dynasty's science and technology tree back then, and was tricked to death by the whole aristocratic family. The time traveler who killed Silence is now in Chang'an City, holding a high position of power, waiting for the "latecomers" to come to his door every day. And Li Shimin, who had "a lot of drama in his heart", became furious when he saw him for the first time: "Come here! Drag this kid down! If you dare to talk about the 'round earth theory' in front of me, I will let you roll around on the ground yourself!" Chen Yan looked at the sign in his hand that read "Cui's Paper Factory Handyman" and then looked in the direction of Chang'an City: "Senior, do you call this experienced?" Silence lasted three seconds: "... At least you're not dead, right?"
