In his previous life, a bridge collapsed when he was building it. When he opened his eyes, he became the third prince of the Tang Dynasty. He was kicked by his own father and sent to the troubled land of Lingnan to work on construction. Fortunately, there is a system tied into it - farming can be exchanged for grain seeds, building roads can be exchanged for blueprints, and cooking can be exchanged for people's hearts. He originally wanted to make a fortune in silence, but the railway was built to Chang'an, the helicopter flew into Tai Chi Palace, and the whole family chased him from the capital to Lingnan with a bowl in hand. The historian asked him what he wanted, and he said: "I want a big table that can seat everyone. A hot meal that can be reheated when it's cold."
