Great Tang: After Fifteen Years of Sign-In, Empress Zhangsun Reveals My Identity

Qin Yun transmigrates to the Tang Dynasty and becomes the eldest son Li Shimin and Empress Zhangsun lost to the common folk. After awakening the God-Tier Sign-In System, he is adopted by the abbot of a Taoist temple outside Chang'an.

After signing in at the temple for fifteen years straight, the abbot passes away, and Qin Yun inherits the temple.

After saving several villagers who were close to death, he is regarded as a celestial being by the locals.

When Li Shimin hears about him, he sends for Qin Yun to come to the palace and treat Princess Changle's respiratory illness. But seven moles on Qin Yun's arm give away his identity to Empress Zhangsun.
