The third level is deep dream sleep. To this extent, consciousness has sunk into dreams. You can't be aware of yourself in a dream. He began to immerse himself in strange dreams with the divergence of his subconscious mind.

The fourth level is deep sleep. Even the dream is over and the mind stops completely. Decreased physical function and metabolism. The brain is at rest. In this sleep state, human sleep quality is the best. The brain can also get the greatest relief.

Four levels of sleep state, according to people's mental state, fatigue degree and physical condition, not everyone can quickly enter the fourth sleep state.

Some people toss and turn all night, often wandering between the first sleep state and the second sleep state. There is no way to enter the fourth sleep state. The rest quality is very poor.

In this screen star world, after research, scientists have found a way to help human beings have high-quality sleep.

By studying the mental fluctuations of extreme exotic animals, they created an instrument that can release low-intensity hypnotic waves. As long as humans wear this instrument, they can quickly enter the fourth sleep state through hypnotic waves. Get a quick rest in a short time.

But even so, people in this world can get a quick rest with the help of instruments, but according to scientists, research on the human body believes that. Even if you are completely in a state of high-quality sleep, and use intermittent rest. That is, work for a period of time, and then sleep for a while. Get up again, continue to work and have a rest. With such a full rest, humans need to sleep for at least four hours.

Otherwise, even if you can fully alleviate mental fatigue. Keep your work free from drowsiness. However, the skills of human organs are too much, which leads to loss or premature aging due to excessive operation.

Pro yuan discount also only sleeps two hours a day, which is completely overloaded under the condition of wasting their own health. He did his best for this No. 7 research metropolis, because he did his best for the peaceful coexistence of mankind and research animals in this world.

For such a temporary original discount, Xiao Zhi still appreciates it very much.

After receiving Xiaozhi's spiritual voice, Linyuan immediately put down his work and asked people to prepare for the reception. And Xiaozhi, with angelica, also fell down.

Although Angelica has resigned, many people still regard her as the queen of area 2. The pro yuan discount is no exception to this. He asked someone to prepare the highest etiquette for angelica to receive foreign guests in area 7. At the same time, Linyuan also asked people to send a letter to the No. 2 research area. Their queen Angelica has asked the Lord of destruction to save herself to the No. 7 research metropolis.

In fact, there is no need to send a telegram to area 2. When Xiaozhi came to the No. 4 research area with Angelica five, their video data had been photographed by spies in other areas for the first time, and then sent back to their respective homeland.

Although these spies have returned, they have been buried with No. 4 research metropolis. But now, high-level officials in all parts of the world basically know. The God of destruction came to area 4 with queen Angelica of area 2 and four other women suspected of being secret soldiers of area 4, and dealt a devastating blow to area 4!

Now Xiaozhi returns to area 7 with angelica, which, to some extent, just verifies the correctness of the previous intelligence. In addition, since the God of destruction has returned to the No. 7 research metropolis with the queen of area 2, doesn't it mean that the No. 4 research metropolis is completely over?!

The image sent back by those spies before was that Xiaozhi threw the huge ball of light towards the earth, but then the picture was interrupted. Despite their speculation, most of the No. 4 research metropolis is over. But no one can be sure until now.

"Under the crown, the matter of No. 4 research metropolis has been solved?" Linyuan also asked Xiaozhi.

"It's solved. I've destroyed the whole No. 4 research metropolis. As for the remaining people in No. 4 area, I've asked people to integrate them. I believe there should be no more trouble in No. 4 research metropolis." Xiao Zhi said so.

In the face of Xiaozhi's words, Linyuan's eyes couldn't help but emerge. The whole city of No. 4 research metropolis was destroyed and countless people died.

But these are also the way for people in area 4 to die.

Others don't know, but the original discount is too clear. Originally, Xiao Zhi was not prepared to start with the No. 4 research metropolis first. On the contrary, in Xiaozhi's original idea, area 4 can still be saved. On the contrary, it is the No. 6 area, that extremely militarized area. Their ideas are stubborn and single, passed down from generation to generation, and it is impossible to change them.

So Xiao Zhi plans to wait until the time of the ultimatum passes and go to area 6. Divine punishment. And use the destruction of area 6 to deter area 4. Unexpectedly, area 4 killed itself. It even sent fighters and colonization armor to intercept and kill fighters in area 2, and even attempted to plunder the body fragments of neklozma.

This completely angered Xiao Zhi. That's why Xiaozhi will personally take action and go to area 4 to lower the divine punishment. And Xiaozhi, the reason why she let them go is not just a simple reason for fate and fate.

But because, when they were born, they were all kind people. It was only because of the destruction of fate that they had to become ruthless killing machines. It was because he saw their fate that Xiaozhi didn't kill them. Instead, they want to make them their wives.

It's like a five river piano. Her arrogant and irritable character is not what she was originally like. She as like as two peas, but now she looks exactly the same as her timid character.

When she was young, she once raised a very strange animal called Mianmian Mian rabbit. This is a kind of extreme beast with low racial value and poor talent. But Wuhe Qin likes this rabbit very much. She took good care of it and regarded it as her good friend.

Then one day, the parents in Wuhe Qin killed the rabbit. After dissecting the Mianmian rabbit, it was returned to the Wuhe Qin. Then tell her that as a member of the Wuhe family, it's wrong to get tired of small animals all day. It's playing with things and losing heart! Your brother, when you are so old, has been able to do it by himself and successfully dissect and study extremely exotic animals with excellent technology.
