Qin Shihuang encountered a major mistake in unifying the six countries and was blackmailed by his old general. But instead of being angry, he smiled happily, because he thought the veteran would bring him a certain threat, but the blackmail of the veteran meant that he did not threaten his position, so he smiled.

At that time, Qin Shihuang wanted to attack Chu. He asked his general Li Xin how many people were suitable, and then Li Xin confidently replied that sending him to 200,000 people was enough. Then Qin Shihuang asked General Wang Jian, who said that it was absolutely impossible for him to be sent without 600,000 people. Then Qin Shihuang said humorously that it might be that General Wang was old and had no military spirit. Later, Wang Jian went back to his hometown to recuperate, and Qin Shihuang ordered Li Xin.

Qin Shihuang was very angry about this matter, so he went to invite Wang Jian, who was already terminally ill, and wanted General Wang to attack Chu again. Wang Jian finally agreed to take 600,000 soldiers to attack Chu. Before they left, Wang Jian told Qin Shihuang that he wanted Qin Shihuang to give him a lot of farmhouses and official titles when he returned triumphantly, but Qin Shihuang didn't understand why the old general was still thinking about wealth and status when he went out to war. Then Wang Jian said that he had been playing for decades, and Qin Shihuang didn't even give him a title. Now he wants to buy something for his descendants, hoping that they can live a rich life.

When Qin Shihuang heard the general's threats, he immediately beamed, because he felt that Wang Jian was loyal to him and didn't want to establish a certain monarch himself, so Qin Shihuang was relieved and didn't get angry.
