Zheng Yun: "Liao, Liao, Liao, Dr. Liao", Dr. Liao: "How is it, excited", Zheng Yun: "Dr. Liao, is this true", Dr. Liao: "Of course it's true, I thought it would never be used", Zheng Yun walked over excitedly, picked up a mechanical hand and touched it excitedly, Zheng Yun: "Dr. Liao, can I try it", Dr. Liao: "Of course, this was originally tailor-made for you", Zheng Yun was excited and immediately put on this set of mechanical armor, Dr. Liao: "How is it, does it fit", Zheng Yun: " It's just right, it fits too well", Dr. Liao: "Take two steps and take a look", Zheng Yun: "Okay~ uh... Raise your feet", Zheng Yun fell to the ground with a bang, Dr. Liao touched his head: "Ahhh~ I forgot to turn on the electricity", Zheng Yun shouted angrily: "Dr. Liao!! Dr. Liao: "Okay, you try again", Zheng Yun slowly stood up, walked back and forth, Dr. Liao: "Okay, okay, don't go, I'll tell you about the function of the armor", Zheng Yun: "Oh~", Dr. Liao: "It's not good to demonstrate at school, you take it off first, after school, we'll see you in the back mountain", Zheng Yun was very reluctant to take off the armor, Zheng Yun: "That, after school, see you in the back mountain", Dr. Liao: "See you in the back mountain".

Zheng Yun returned to the classroom, Dr. Liao continued to investigate, Dr. Liao: "This is ......".

After school, Zheng Yun walked to the back mountain excitedly, Ye Ning: "Zheng Yun, where are you going if you don't go home", Zheng Yun: "Ah~ I'm sorry, you can go home by yourself today, I still have something to do with Dr. Liao", Ye Ning: "Don't be too late", Zheng Yun: "Got it".

Zheng Yun came to the back mountain, Dr. Liao was alone in the bitter contemplative, Zheng Yun: "Dr. Liao~", Dr. Liao did not agree, Zheng Yun walked to Dr. Liao's side, and suddenly shouted in Dr. Liao's ear: "Dr. Liao!" Dr. Liao was taken aback, Dr. Liao exhaled, Dr. Liao: "You are here", Zheng Yun: "Dr. Liao, where is the armor", Dr. Liao said in a low tone: "Zheng Yun~", Zheng Yun: "Huh?" Dr. Liao: "Zheng Yun, we won't be involved in this matter", Zheng Yun: "Dr. Liao, what's wrong with you", Dr. Liao: "I'm too naïve", Zheng Yun: "What are you talking about", Dr. Liao: "Originally, I wanted you to wear armor to reconnoiter why this phenomenon happened in these two cities", Zheng Yun: "So why don't you do it now, I'm still waiting to get out of this boring day", Dr. Liao: "I remember the first time we met, you sighed all day, Why is this world so boring, now that I think about it, I'd rather this world be so boring forever", Zheng Yun: "What are you talking about, why don't I understand", Dr. Liao took out a tablet and showed Zheng Yun the photos inside: "Look at this", Zheng Yun took the tablet, "What's wrong, isn't this a photo of the police helicopter explosion in the morning", Dr. Liao: "This is taken by satellite, you look more carefully", Zheng Yun looked at the picture carefully, Zheng Yun: "Ah! This is! Feather? Dr. Liao: "That's right, you're looking at other photos", Zheng Yun continued to look at other photos, Zheng Yun: "This, how is it possible", Dr. Liao: "I didn't believe it originally, but the model of the plane I sent was also...", Zheng Yun: "This must be just an accident, besides, how can such a small piece of feather blow up a helicopter", Dr. Liao: "It's not just that, the city can't get in, and the people inside can't get out either, and the contact has also been cut off, and it is completely impossible to get the contact inside, There is also the worst thing", Zheng Yun: "What's the matter", Dr. Liao: "The satellite has begun to get out of control and is slowly landing in the city", Zheng Yun: "How come, Dr. Liao!" Isn't there a way to stop the satellite?", Dr. Liao: "Give up, it's not something we can stop", Zheng Yun: "Dr. Liao, what's wrong with you, this is not like you", Dr. Liao: "Yes, it's not too early, you should go home quickly", Dr. Liao left dejectedly, Zheng Yun: "Dr. Liao! Don't you care about the life or death of the city", Dr. Liao paused, and then left, Zheng Yun whispered: "Dr. Liao~".

Zheng Yun returned home, Zheng Yun's mother: "Come back~ Where did you go in the morning, I heard Ye Ning say that you were not at school in the morning", Zheng Yun hung his head dejectedly: "I'm back in the room, don't call me if you don't eat dinner", Zheng Yun's mother: "What's wrong with you".

Zheng Yun returned to the room, lay on the bed, and remembered what Dr. Liao had told him, "The satellite has begun to get out of control and is slowly landing towards the city, is there no way to stop the satellite?" Give up, it's not something we can stop", Zheng Yun was very angry and grabbed the pillow and smashed it on the ground, and roared, "Ah~~~", Zheng Yun's mother: "Zheng Yun~ What's wrong, what's going on", Zheng Yun: "No, it's okay", Zheng Yun's mother: "Just sleep well if there's nothing to do, everything will get better when you wake up", Zheng Yun: "Got it", Zheng Yun: "That's right, this must be a dream, as long as you wake up, nothing happens, yes, sleep".

The next morning, Zheng Yun got up and walked downstairs, Zheng Yun: "Morning", Zheng Yun's mother: "Zheng Yun, why are you so well-behaved today, you can get up by yourself, wait a minute, breakfast will be ready immediately", Zheng Yun: "Mom, why is it so hot today, didn't you look at the air conditioner", Zheng Yun's mother: "It's strange to say, the air conditioner is not cold at all, the fan is also on, there is no wind at all, you go to see if it's all broken", Zheng Yun: "Oh~", Zheng Yun checked the air conditioner, Zheng Yun: "It's strange, the air conditioner is fine, Why is there no wind coming out", Zheng Yun went to check the fan again, Zheng Yun: "It's so hot~ This fan is fine, it can turn, why is there no wind coming out", Zheng Yunmu: "How is it, is it done", Zheng Yun: "Strange, the fan and the air conditioner are fine", Zheng Yunmu: "If you can't get it, forget it, hurry up and come over for breakfast".

Zheng Yun went out after breakfast, Ye Ning pushed the bicycle out very unmotivated, Zheng Yun: "What's wrong with you, why do you look like you have no energy at all", Ye Ning: "Morning~ I don't know what's wrong today, the air conditioner has no wind at all, and it's so hot that I can't sleep all night", Zheng Yun: "Your air conditioner has no wind?" Ye Ning: "You mean your family too", Zheng Yun: "Yes, it's really weird", Zheng Yun suddenly stopped the car, remembering what Dr. Liao told him yesterday, Ye Ning: "What's wrong", Zheng Yun took out his mobile phone to call Dr. Liao, "Dudu Dudu", Zheng Yun looked at the phone, Zheng Yun: "Why is there no signal, Ye Ning, pick me up on your mobile phone", Ye Ning: "Oh~", Ye Ning took out the mobile phone and handed it to Zheng Yun, Ye Ning: "What's wrong", Zheng Yun looked at Ye Ning's mobile phone and found that there was no signal either, Zheng Yun: " There is no signal", Ye Ning: "How is it possible", Ye Ning took the mobile phone and looked at it, Zheng Yun suddenly stepped on the bicycle and accelerated to the school, Ye Ning: "Hey~ Zheng Yun, wait for me", Zheng Yun stepped on it quickly, Ye Ning couldn't catch up, Ye Ning: "Really".
