Shenma's answer, let's make it clear.

It was just a few months ago. There was a child whose parents were out at night, and he was home alone. Since the child didn't believe in any gods, he wasn't afraid.

This is the question of "what are you afraid of?" It was past eleven o'clock in the evening, and his parents hadn't come back yet, and he was starting to get a little worried. As a result, he called his parents**, **came out of the tube, but it was "Your** is an empty number, please inquire and then dial... The child was so frightened that he called the police.

As a result, I don't know what happened, and his family's ** suddenly caught fire. The kid screamed and ran out, and they were locked up. He looked at the wall in despair.

Scared the hell out of me! The child woke up and found himself dreaming. This is, a woman brought a towel and wiped his sweat.

Then the child fell asleep. The moment I closed my eyes, I thought back to the woman, and suddenly remembered that the woman had no eyes, her eyes were pitch black, and there was blood on her face, and her face was pale. He shouted:

Yes! Help, come on! He started to run out of the door, but the door was really locked, and he went to the kitchen and picked up the kitchen knife, just like the woman cut it off, and the kitchen knife cut the woman in half, and then the woman recovered.

Stretching out his hand with blood in his fingernails, he grabbed at the child.

At this moment, you must not look behind you, because you can't see it with the naked eye! If you don't copy this post to 3 people, at 4 a.m., you're going to die...

3x=5（x-4）

x=10
