Datang: Saving the People to Immortality

In the second year of Kaiyuan, Tang Ning traveled through time and opened the merit system. As long as it promotes social progress, it can be exchanged for physical objects and technical materials. The most important thing is that it can be exchanged for life span. Tangning owns a mansion and is still thinking about making money. Unexpectedly, someone came to visit, one named Li Sanlang and a high guard. After drinking for three rounds, they started talking nonsense and asked about some important national affairs and people's livelihood plans. If it wasn't for the purpose of promoting social progress, Tang Ning patiently explained to them and even gave them a few gifts. "This is how to make soybean oil." "This is a telescope. You can see ten miles away." "This is paper. It costs less than ten coins and can be purchased for ten coins." Finally, Tang Ning was about to become immortal. However, Li Sanlang quietly told Tang Ning: "Mr. Tang, actually I am the Emperor of the Tang Dynasty, Li Longji." .... This novel and its characters are purely fictitious.
