Great Tang: Saving the People Until They Live Forever

In the second year of the Kaiyuan era, Tang Ning transmigrates to this world and activates the Merit System. By advancing society, he can exchange merit for physical goods and technical knowledge. Most importantly, he can even exchange it for extra years of life.
