Ling Chen physically traveled to the Tang Dynasty and appeared directly in front of Li Shimin!
Fortunately, the system woke up in time. With the help of the system and Ling Chen's understanding of history, he successfully deceived Li Er and became the Grand Master of the Tang Dynasty.
From then on, the Tang Dynasty allowed me to live freely.
Princess Changle: Lingchen, I want to marry you.
Li Yuan: Brother, let's become sworn brothers.
Li Shimin: Imperial Master, it's okay for you to marry my daughter. Why are you still sworn sworn friends with my father? How do we calculate our seniority?
Ling Chen: Your Majesty, let's talk about our own affairs. I'll call you father-in-law, and you'll call me uncle, hehe.
