The third level is deep dream sleep. To this extent, consciousness has sunk into dreams. I can''t realize that I''m 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 body 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 humans sleep with high quality.


    By studying the spiritual fluctuations of extreme 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, human beings need to sleep for at least four hours.


    Otherwise, even if you can fully relieve mental fatigue. Let your work be free from sleepiness. However, the human organ skills are over operated, resulting in loss or premature aging.


    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 human beings and research animals in this world.


    For such a pro 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 reception. And Xiao Zhi, 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 own 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. Although they have guessed, 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?" Lin Yuanzhe also asked Xiao Zhi.


    "It''s settled. I''ve destroyed the whole No. 4 research metropolis. As for the rest of the 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." Xiaozhi said.


    Facing 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. Xiao Zhi was not prepared to start with the No. 4 research metropolis. 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, inherited 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. They even sent fighters and strong colonial 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 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 originally, 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 at first. 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 rabbit. This is a kind of extreme beast with low race 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 Mianmian rabbit. After dissecting Mianmian rabbit, he returned it to Wuhe Qin Li. 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, at your age, has been able to dissect and study extremely exotic animals by himself and with excellent technology.
