Zhang Yang traveled across the Qin Dynasty and became an orphan adopted by Zhang Liang's father. The original owner had been brainwashed by Zhang Liang since he was a child and was preparing to assassinate the First Emperor in Bolangsha.
The male protagonist has just traveled through time and found himself in Bolangsha. He was brainwashed and arranged to be cannon fodder for his abandoned son. When he was complaining in his heart, his voice was suddenly heard by Ying Zheng from the East Patrol Team who arrived.
Ying Zheng discovered the conspiracy through his voice, and was shocked and curious about the identity of the male protagonist.
After destroying Zhang Liang's assassination plan, Ying Zheng discovered that Zhang Yang did not want to rebel, knew historical secrets, and had magical future technology. He decided not to expose his identity, but deliberately reused it to develop and strengthen the Qin Dynasty, and to limit and control the remaining parties in the six countries and destroy the anti-Qin plan of the remaining parties in the six countries.
