During the Ming Chongzhen period, there was a young man named Xie San in Jingzhou, Hubei Province. He was usually idle and doing nothing, and often hung out with a group of local rascals.

One day, he was building a wall in the vegetable garden behind his house during the day, but it was not repaired after a day. When he went to bed at night, he suddenly had a dream. In the dream, he saw a beautiful woman in beautiful makeup bowing down in front of him: "I have been cultivating underground for hundreds of years, and I see that I am about to complete my work, but there will be a catastrophe that will be impossible to escape tomorrow, and only you can save me. There is an ancient mirror on my chest, remember not to take it away, just hide me again, and I swear that I will repay you heavily in the future." After these words, Xie San was awakened. He looked around for a week and there was nothing abnormal, but he still remembered the scene in the dream very clearly.

The next morning, he and a few servants continued to repair the wall in the vegetable garden. When they dug more than a foot deep into the wall with a hoe, they suddenly felt as if they had touched something. They continued digging deeper and found a black lacquer coffin.

Xie San and the servant were both very surprised, so they cleaned up the dust on the coffin lid and found that there were three horizontal and vertical rows of words engraved on the coffin lid, which were difficult to identify if it was not a scribe or a seal seal, and seemed to be quite old. Xie San and the servant curiously opened the coffin and found that there was a young and beautiful woman lying inside, only to see that she was wearing ancient costumes, her face was serene and lifelike, as if she was asleep, and what was even more surprising was that there was a mirror with a diameter of three inches hanging on her chest.

At this time, Xie San suddenly remembered the dream he had last night, and found that the woman in the coffin was actually the person in the dream. He remembered what the woman said again, and he was a little scared, so he prepared to close the coffin and bury the coffin again.

At this time, a servant standing next to him suddenly pointed to the mirror and said to him, "This ancient mirror is shining brightly. In my opinion, it must be extraordinary, and it must be a treasure. Just take it away, she is just a corpse, what is there to worry about?"

Hearing this, Xie San couldn't help but move in his heart. He loved money as much as his life, and when he heard it, he was greedy and put the woman's words behind him, so he obeyed the servant's words and carefully took the mirror off the woman's body. Unexpectedly, as soon as the mirror was taken off, the woman's body turned to ashes in an instant. At that time Xie San felt very scared, so he quickly buried the coffin on the ground with a few servants.

When he went to sleep at night, Xie San dreamed that this woman came to him crying and said, "I have already completed my transformation, but you have destroyed my Dao Line. This is also a doomed disaster, how can I resent you? But you should cherish this ancient mirror, so I will definitely bless you in the future." After that, the woman disappeared.

After waking up, Xie San was very surprised. From then on, he enshrined the mirror at home as a treasure, and worshipped it devoutly every morning and evening.

After a while, the ancient mirror suddenly made some strange sounds from time to time, and Xie San felt very strange. One night, he dreamed that the woman said to him: "Yang Xianggong (Yang Sichang, Wanli Jinshi, Chongzhen's right servant of the Ministry of War) is currently recruiting talents from all over Jingzhou.

Then in his dream, he taught him a lot of corresponding strategies for military and political affairs. After Xie San woke up, he found that what the woman had taught was in his heart. He was secretly happy, so he went to see Yang Xiangguo early in the morning.

When Yang Xiangguo heard that someone was called, he hurriedly invited him into the mansion to talk about the military affairs with him, and Xie San was eloquent and analyzed the current form. After hearing this, Yang Xiangguo was greatly admired and thought that he was a rare talent, so he took him as his staff and stayed in the mansion. Every time there was a march and battle, he was asked to make suggestions and participate in the decision, and he was actually invincible.

Yang Xiangguo was very happy, and was ready to go to court to appoint Xie San to an official position. At that moment, the servant who had persuaded Xie San to take the mirror away angered him because of a small mistake. Xie San was furious and couldn't control himself. He immediately beat him with a whip, but he accidentally beat him to death in his rage. Seeing human life, Xie San was terrified, and he was uneasy all day.

At night, he dreamed that the woman said to him, "There is no need to be afraid of such trivial matters. You just need to tell Yang Xiangguo that you need to take a few days off to go home and rest, and then take the opportunity to wrap the body tightly and pull it out in the car. I will definitely be able to protect you."

Xie San obeyed her words, so he hid the body and pulled it out of the car as she said. Unexpectedly, when he reached the gate of the barracks, blood suddenly flowed into the car. The guard was very shocked and immediately stopped him. After carefully checking the car, he found the body, so he quickly reported the matter to Yang Xiangguo.

The Prime Minister summoned Xie San to ask, and Xie San did not dare to hide it, so he told the truth about manslaughter of the servant. Yang Xiangguo asked him some military and political matters by the way, but he suddenly forgot what the woman had taught.

Yang Xiangguo couldn't help but be furious and wanted to take him down for punishment. Xie San was terrified, so he told Yang Xiangguo the origin of the mirror and said that it was all taught by the woman in her dream.

After hearing this, Yang Xiangguo was very surprised. In order to prove whether Xie San's words were true, he immediately sent someone to his house to get a mirror. As a result, before the person who took the mirror reached his mansion, the mirror suddenly made a loud noise, and instantly rose into the air and turned into a white light.
