Great Tang: From the Start, I Treat Empress Zhangsun

In the seventh year of the Zhenguan era, Li Xiaren, the fifteen-year-old eldest legitimate son of Duke of Wei Li Jing, awakened a daily sign-in System!

Signing in granted him immortal techniques and could also unlock futuristic technology. Just then, Empress Zhangsun's asthma took a critical turn, and the imperial physicians were helpless. Li Xiaren stepped in and saved her with his immortal medical arts.

At a palace banquet, he spoke bluntly about the dangers of close-kin marriage, successfully ending Princess Changle's betrothal. Li Shimin joked that if Li Xiaren could cure Princess Runnan, he would marry both daughters to him.

Once Runnan recovered, the Emperor couldn't take back his royal decree. Armed with extraordinary skills, the young man stirred up the Tang Dynasty. Both princesses stayed devoted to him, while powerful families at court repeatedly made trouble for him.
