A history student left the Qing Dynasty and traveled through the Warring States Period. When he opened his eyes, he turned out to be Qin Shi Huang's brother living among the people.
He originally wanted to live anonymously, but he was targeted by Ying Zheng because of a broken jade.
Discussing politics in the teahouse, he praised the Emperor of Qin for "exchanging the suffering of one generation for peace for a hundred generations"; during the duel in the palace, he proposed flood control strategies that directly pointed to the lifeline of the empire.
Ying Zheng appreciated him, reused him, and investigated him thoroughly - until the jade Huang revealed the bloody truth.
"Zhao Zheng, what if I told you that the 'remnant of the previous dynasty' you are so hard to kill... Is your biological brother?"
The iron law of the Qin Dynasty comes first, and the conspiracies of the Six Kingdoms follow.
This time, in the name of his brother, before the history books are burned, he will leave a sentence for the lonely emperor:
"Brother, I will accompany you on this road."
