During the Warring States period, Zhang Ug, a strategist of the State of Qi, went to the State of Yan as a hostage, because he angered the King of Yan and the King of Yan decided to kill him. Zhang Ugly noticed it and secretly escaped.
King Yan drew images and arrested him all over the country. When Zhang Qiu fled to the border pass, he was caught by the guards and wanted to escort him to the capital to ask for a reward.
Zhang Ugly was in a desperate situation at this time, there was only one way to die, but he thought: Why should the eldest husband wait for death in vain, he should survive in death. So he came up with a wonderful plan and said to the officials guarding the pass, "Do you know why the King of Yan wanted to kill me?" The customs officer said, "I don't know, I just know how to arrest people."
Zhang Ugly said, "The reason why king Yan wanted to kill me was because he heard people say that I have a jewel, and king Yan wants me to have this pearl, because it is a priceless treasure and is extremely valuable." But this jewel was lost in my running east and west, and I couldn't get it out, so I told it to the King of Yan, who didn't believe it, saying that I didn't want to give it to him, so he wanted to kill me, so I had to run away.
If you take me to the capital and the King of Yan asks me for the jewel, I will say that you have robbed me, and you have swallowed it and preserved it. In order to get the orb, the King of Yan will inevitably cut open your stomach, cut open your stomach, and look for it one by one; Cut off your intestines again, search inch by inch, and then I will not be able to live, and you will only die."
When the official who guarded the customs listened, he broke out in a cold sweat and thought to himself: Not only will I not receive a reward for escorting him to the capital, but I will only have one way to die, so it is better to let him go. So when it was late at night, he quietly released Zhang Ugly from the gate.
