The director of the detective agency didn't expect Chu Tianying to be so good and make such a complete record of the Liu family's affairs, and besides, Chu Tianying almost told the robot about it.

Because he thought of Jiang Linda and had to protect her, he deleted the part of the robot, and it was inconvenient to say it, but he recorded the location of the Liu family and the dragon horn of the Liu family and so on, very completely, in this way, as long as it was handed over to the police, and then conducted a field investigation, after the mixed evidence was conclusive, he could go to the Liu family to get someone, there was a security guard in the Liu family who was very suspicious, and in addition, the housekeeper may have a copy of the key, which is the object of their suspicion.

And Jiang Linda and them, Qin Shuai followed her, driving all the way bumpy, and finally arrived near the square where the clown performed before, there are many food shops in that place, and there are also ATMs, Linda asked Qin Shuai not to be excited, so she only took out tens of thousands of yuan, bought a lot of food, and left a lot of money, Qin Shuai wanted to buy some toys and so on for those children, but Jiang Linda disagreed, she said that in the current situation, as long as you buy some daily necessities, you can do it, but Qin Shuai is afraid that these children will be bored in the tent, Anyway, I finally fooled Linda into a nearby toy store and bought some toys for the children.

Jiang Linda drove the car and looked at Qin Shuai, the little toys he was playing with all the way, he was very curious, and he also felt that he looked like a child who didn't grow up: "You have been playing with these things all the way, do you plan to invent toys in the future, or do you have a low IQ, or do you have a special hobby." ”

Qin Shuai looked innocent: "How can there be?" Don't be sarcastic about me, I think these toys are cute, I gave them away immediately, I haven't played with them yet, and I really didn't have so many toys since I was a child, and I didn't ask my adoptive father for them, I knew I was an adopted child, and I was embarrassed to ask him for money. ”

"So you're all about learning, so you've invented so many things, haven't you?"

Qin Shuai actually didn't dare to say that he was talented, there were things he could never forget as long as he saw them, and then he could invent them, he didn't want to tell Jiang Linda about this power, so he said yes.

Linda gave him a part of the food in the car, so that he could eat first, and then they went to visit those refugees, in fact, they all had money in their hands, and some of them ordered several dishes for takeout, I don't know what Qin Shuai thought, he always wanted them to eat better, use better, and they were about to catch up with their food and clothing, if such a person wanted to be a leader or a chief, he would definitely love the people like a son in the future, but he was too young now, and he was just a non-commissioned officer.

When the two of them were rushing back towards the route they had come, they suddenly encountered a sloping dirt slope, they remembered that they had not passed by this place before coming, it seemed to be a temporary construction, this soil slope was some reinforced concrete, temporarily buried soil, as if there was a war situation.

They were stopped by the flag-bearers and told them to get out of the car quickly, because aliens had just attacked the area in the nearby clouds, but fortunately there were no casualties. But rows of bullet traces can be seen on the land here, but they said that it was caused by the shells thrown from above, the more Qin Shuai looked at it, the more it looked like a machine gun, and if the machine gun was fired from the clouds, it was too unbelievable outside, Qin Shuai immediately hid with Jiang Linda near the dirt slope, and saw that the people of the Alliance Army were facing the sky, and many of them were people from Sergeant Zhang's side.

One of them came to protect them: "Now that there is war again, you must be careful and hide this car in the bushes, otherwise, it will be a pity if you bomb this car, by the way, did you borrow this car or your own?" ”

There was a person who had met Qin Shuai before, as if he was familiar with each other, because when Qin Shuai bombed the black hot air balloon before, he had followed Sergeant Zhang here, so he knew Qin Shuai, but he was not very familiar with it, and Qin Shuai told him that the car was indeed borrowed.

In fact, it was Chu Tianying's car, so they immediately hurriedly drove the car into a bush and hid it, and the people also hid it in the bushes.

In the dense clouds, a row of armor flew over like a helicopter, but the wing part was very huge, in fact, it was unknown where their gun muzzles came from, crackling and strafing, and small craters appeared on the ground, but they did not attack any soldiers, they retracted into the dense clouds, but Qin Shuai immediately looked for nearby bullets from his signal instructions, he quickly dug out of the soil, and found that it was machine gun bullets, but they fired machine guns from the dense clouds, It's still a little strange, but this machine gun doesn't shoot in a straight line, but a diagonal line.

Taking advantage of the quiet moment, a few young soldiers next to him came over and asked him, what kind of bullet is this? Qin Shuai explained to them the things of machine guns: "Machine guns, in order to meet the stable needs of continuous shooting, are usually equipped with bipods and can be installed on tripods or fixed gun mounts, mainly firing rifle bullets or larger caliber bullets, can shoot quickly and continuously, with strafing as the main attack method, according to the principle of automatic, it can be divided into two categories, one is an external energy machine gun, the other is a machine gun powered by gunpowder gas, and the latter can be divided into tube retreat, air conduction, free bolt type, hybrid type, etc., The bullet we see is similar to him, but it does not belong to it, but uses these things to remove its dross and study its essence to make it. ”

He also said: "Most of the automatic machine guns powered by gunpowder gas are gas conduction, and a few are short recoil barrels or bolt recoils. Some barrels can be quickly replaced when overheated, making them suitable for continuous firing for long periods of time...... Some of the ammunition supply methods are mostly supplied by chains, and some are supplied by magazines or drums. The launch mechanism generally adopts a burst structure. Tank machine guns, ship machine guns and aviation machine guns are mostly machine guns with an automatic structure of external energy that are electronically controlled and fired. The crops we just saw were actually a kind of flying device extracted from this, but how they managed these special machine guns is still unknown, so we must be cautious, guard against it, and be cautious. ”

He also knew that most machine guns also had a horizontal gauge for firing at moving targets or for wind deflection correction. The anti-aircraft machine gun was equipped with an improvised mechanical sighting device or an automatic vector sight.
