He was also bound to the time-travel system. As soon as he arrived in the Tang Dynasty, he faced provocations from envoys from neighboring countries. With the support of the system, he excelled in horse-riding, archery, fist and kick competitions, shocking everyone. But this also aroused the jealousy of other princes.

He continued to recruit talents and formed a think tank. In the turbulent power struggle of the Tang Dynasty, he gradually established his own power and marched towards the supreme throne.
