Qin Shuai's tracking robot went up to this roof, installed something like a pinhole, and drilled into their ceiling.

Immediately opened a hole, arranged a miniature camera to observe and watch these agents pretending to be children, and transmitted their videos to Qin Shuai in time, Qin Shuai observed, in fact, they all have chips, but the teachers on the earth can't see it, so these children seem to be very quiet in this classroom, in fact, they are constantly learning the knowledge of earthlings and transforming it into their own energy.

In today's class, the teacher arranged test papers for them, and some children who studied well began to do it silently. But these people are high-tech alien robots, and they can do it quickly, but they have to pretend they can't.

Some pretend to be meditative, frowning, some hold their cheeks, looking naïve and cute, in fact, they are all disguised these things, they only need to scan through their electronic eyes, and then open the knowledge base, they can completely answer, and can get 100 points, but some deliberately do not seem to be, and wrote a few wrong questions. When the teacher criticizes, they absorb this energy from the teacher, and this energy can be transmitted to their control system and then processed into special energy.

The more earthlings express their emotions, the more they acquire this pattern of emotion, so the higher the energy value they will get.

The teacher's tone in the classroom, the lecture like a colorful voice, has been entered into their sensing system, some of the energy value, will transmit the advanced energy value to the signal system, sent to the alien observation system, and then they will develop and research a new batch of intelligent robots, will have this mode, with a variety of emotional changes.

When Qin Shuai was observing these things, Qin Chuan's phone called, asking him if he had time in the past few days, everyone can get together, because recently he has made new friends in the military region, and they are also doing intelligence work, but because they are more kind, they get along very happily, and I also hope that Qin Shuai will meet some new friends, but Qin Shuai is now imminent to observe these things, and he is about to invent his own tracking system, so he can only refuse, but there should always be a reason for refusing Qin Shuai, He didn't know where to start.

Because these things are no different from intelligence, it happened that Linda's news came over, Qin Shuai asked her if she could help her act in a play, Linda knew that Qin Shuai was researching a secret weapon and agreed to him, so the two of them said that they were going to dinner, and they were going to have an engagement banquet, Linda used this method every time, in fact, it was also embarrassing, but there was no other better way to refuse Qin Chuan's hospitality.

At the appointed time, the robot came down from the roof, had obtained the agent's general information, stored it full, and then hid in the nearby grass, gradually returned, but caught up with the rain, but this rain is different from the previous rain, this rain is artificial rainfall, because this place has been relatively dry recently, and even some notices say that this place has encountered some very dry things, for the needs of crops, flowers and trees, so this artificial rain was done.

However, a special method is used, and the materials used this time are also imported from the alien side, that is, the rain promotion effect is better than before, faster and more timely, but the quality of the rain may not be good, Qin Shuai couldn't help but be a little worried, on the one hand, he was worried about whether these flowers and trees would cause damage? There is also one aspect of some of their own robots on the way.

He controls it himself, of course, he can master it at any time, and he can command them to waterproof, but at the headquarters of the Alliance Army, a batch of his robots have been used, and it often rains these days, and if they take good care of the robots, or if they take training or combat on rainy days, the effect will be greatly reduced.

He was a little anxious, so he called Sergeant Major Zhou, but it was his assistant who answered the phone, saying that Lao Zhou and they were training, and a group of robots had already gone to the battlefield, which was really what he expected.

Qin Shuai thought about whether he should design some waterproof equipment, but seeing that this time was the time he had agreed with Linda to eat, and they still needed to act that scene for Qin Chuan and them to see.

So he had to put down his work, put it aside for a while, and let himself relax a little, so he took his umbrella and walked by himself, intending to go to Linda's side, because she would come and pick him up by car.

In fact, the army can arrange a vehicle for him, but Qin Shuai has never asked for it, because he found that there are some problems with the vehicle here, and only in Linda's car will there be some sense of security, but other vehicles always seem to have some monitoring equipment, and he always vaguely has this feeling.

But the sound of rain falling on the umbrella today was different from usual, in fact, he could always detect some inexplicable subtle feelings. He felt that these things seemed to transmit an inexplicable signal to him, he hurriedly hid near a corner, put down the umbrella, and observed carefully, there were symbols on it, because his umbrella was specially made, it was using the pink substance before, and then he re-colored the umbrella, he liked to make some small inventions when he had nothing to do, and he didn't expect to use it appropriately at this moment.

This is the foreshadowing before the arrival of acid rain, as if these substances, the combined rain is not normal rain, but because they are in a hurry to artificial rain, so they use these things, but now some of the ingredients in it are getting thicker and thicker, and after a while there will be acid rain coming, they actually attracted acid rain, that is, bad elements have been formed in the air, but these responsible experts don't know yet, they really don't know? Or do you deliberately hide from the sky and cross the sea, and wait until the acid rain is coming, and then it rains artificially, can you stop? Do they have what it takes?

Somehow Qin Shuai had an inexplicable worry, but he was not too worried, he only listened to the sound of cars honking on the side of the road, it turned out that Jiang Linda drove over, he got into the car, Linda asked him why he didn't take the umbrella well, seeing that his hair was a little wet, he explained that he had been using the umbrella just now. ……
