Chen Mo, a real estate agent in Hu Piao, discovered one day that his daily routine of showing a house was being broadcast in real time by a strange "live broadcast room", and the audience was actually Qin Shihuang, Han Wu Emperor, Tang Taizong and other emperors throughout the ages. When he explained the room in the school district, the First Emperor angrily commented that it was "comparable to the cost of Afang Palace"; when he showed the model room, Zhu Di disliked it as "not as bright as my military camp". From then on, every business he dealt with became a seminar on state governance across time and space. With the help of the "barrage" guidance from the emperors, he identified treasures, made investment plans, and counterattacked in life. Until one day, the live broadcast signal was suddenly disrupted, and the crisis of space-time interference emerged, and his childhood sweetheart who studied folklore began to smile thoughtfully at the barrage on his mobile phone that only he could see... When modern survival wisdom collides with the ancient emperor's mind, a humble room can also stir up the world.
