Feng San is a fledgling thief. Not long ago, he met a fellow in the rivers and lakes, nicknamed Monkey Four. The two hit it off and became friends.

It is said that Monkey Four has been walking in the rivers and lakes for more than ten years, and has never missed, and even at the last moment, he was able to escape successfully. Feng San admired Monkey Four so much that he couldn't help but ask how Monkey Four did it. Monkey Four looked at him and said mysteriously, "Well, everyone has their own physical condition. Either I don't tell you or I tell you, you can't learn."

Feng San thought that he was deliberately not saying anything, and he was a little unhappy, and his curiosity grew stronger and stronger. Until one day, he saw with his own eyes what Monkey Four was talking about "physical condition."

That night, Feng San came out to step on the spot, and just as he came to the door of a house, he suddenly saw a familiar black shadow leap over the wall and jump into the house. Feng San recognized that the black shadow was Monkey Four at first glance, because Monkey Four usually wore very strange clothes, the upper body was always well dressed, but the pants below were often torn and old, and he was too familiar with Monkey Four's strange clothes. Feng San couldn't help but think: Didn't you refuse to tell me the secret escape technique? Then tonight I'll come and see how you escaped.

After a while, I only heard a shout from the courtyard: "Catch the thief, catch the thief, don't let him run away!" Then the gate opened, and I saw Monkey Four running out of the gate with his bag. Behind him were many strong men with knives and sticks, chasing Monkey Four. Seeing that he was about to catch up, suddenly Monkey Four's feet seemed to be tripped by something, and he fell to the ground with a "plop", one leg exposed from his pants. At this time, a big man rushed up and slashed with a knife, only to hear a "click" sound, blood splattered on his leg, and the chasing crowd was stunned. Monkey Sijuran took advantage of this moment to get up and run, although one of his legs was chopped off, he ran faster than before. Feng San was shocked and quickly caught up with Monkey Four.

Soon they got rid of the pursuers and returned home. As soon as Feng San entered the house, he praised Monkey Four: "Tonight I saw your true ability, you can stand up and run after being chopped off. It's amazing!"

Unexpectedly, Monkey Four heard this and said in surprise, "My legs have been chopped off? What nonsense are you talking about? Are my legs not good?"

Feng San lit the oil lamp and looked down, didn't he? Monkey Four's legs were fine, and he didn't even look injured at all. But at that time, Feng San clearly saw the scene of Monkey Four's leg being cut off by a knife and blood splattered. What happened?

Seeing Feng San's astonishment, Monkey Four finally couldn't help laughing and said, "To tell you the truth, it wasn't my leg that was chopped off by the knife, but my tail. Actually, I'm a lizard man. Like lizards, I have the instinct of tail truncation and regeneration. When in danger, I transform a tail like a leg to attract the enemy, let it cut off, and take the opportunity to escape. And my broken tail has already grown in the process of escaping."

Feng San was amazed when he heard that. No wonder Monkey Four had been stolen for so many years and had never been caught. It turned out that he was born with such a strange escape technique! No wonder he always wore torn and old pants when he went out to steal, because he had to cut his tail at any time he was stealing. If he wore new pants, he would always be cut off, what a pity.

Finally, Monkey Four repeatedly reminded Feng San, "I never told anyone else that I have this special ability. First, I am afraid that others will ignore my own conditions and blindly imitate and harm others. Second, I am worried that if I make this ability public to the world, someone will find a way to deal with me, cut off my wealth and even kill me. So you must not tell others about this, otherwise I will not forgive you!" Feng San nodded and agreed.

From then on, Feng San admired Monkey Four even more, and the two were inseparable, as good as brothers. However, Feng San often lamented why he didn't have the strange ability of Monkey Four.

One day, Monkey Four suddenly panicked and asked Feng San: "Tell me honestly, did you tell others the secret that I am a lizard man?"

Feng San was inexplicably asked, and he swore to God: "Since I promised you, I will never tell anyone. Besides, if I tell others, what good will it do to me?"

Monkey Four felt that Feng San's words made sense, but he still said uneasily, "I have telepathy these days, I always feel that someone who knows my secret is coming to arrest me, or even kill me, who is this person..." In the days that followed, Monkey Four was even more suspicious, often waking up from nightmares, and people were getting thinner and thinner.

On this day, Feng San and Monkey Si went out to work together. They came to the wall of a large house, and Monkey Si said to Feng San, "Don't go in, just meet the wind outside."

Monkey Four immediately jumped into the wall. Not long after, Monkey Four ran out in panic, followed by a big man with a knife. This big man was very strange, not shouting or screaming, chasing Monkey Four while doing somersaults.

Seeing this, Feng San was not in a hurry. He knew that Monkey Four would perform his bizarre escape technique again. Sure enough, just like last time, Monkey Four pretended to fall with a "plop" and then exposed his tail to the big man. It was too late to say, and the big man's hand fell with a knife, and with a "click", blood splashed, Feng San took a closer look, and Monkey Four's head was cut off, and he died on the spot!

Feng San was dumbfounded. He clearly saw that Monkey Four had his tail exposed, but why was his head cut off? After being stunned for a while, he ran forward and asked the big man, "In broad daylight, how can you, how can you kill people at will?"

The big man turned around and did a somersault. He looked at Feng San upside down and said, "I killed a thief, what's your business?"

When Feng San saw him talking to him with the big top, he was even more angry and confused: "You not only kill people at will, but also talk to me like this, are you insulting me Do you still know the royal law?"

After hearing this, the big man laughed out loud, and still stood upside down and said to Feng San, "You don't know about this. I was originally an upside down person. In my eyes, what I see is positive, but in fact it is negative; what I see is negative, but in fact it is positive. Things in this world, only by looking upside down can I see them clearly and clearly!"

Upside-down person! Feng San was stunned for a long time before he suddenly realized: It turns out that this big man is the telepathy of Monkey Four, the person who is afraid of tit-for-tat in the dark. Because the big man has the ability to see the world upside down, the tail he sees is the head, and the head he sees is the tail, so when he slashes at Monkey Four's tail with a knife, it is Monkey Four's head that is chopped off. This really echoes the old saying, one thing begets one thing!

Feng San buried the monkey four, and from then on, he washed his hands in a golden basin and never became a thief again.
