After studying this batch of military robots, they put into the experiment, but the aliens spied on their information, so they prepared to give them a full-scale attack when testing the robots, annihilating all the military robots, and then leaving them without the strength to go to battle.

Both sides have obtained information from each other, this battle is imminent, Qin Chuan feels that the one that has just been produced will be monitored by aliens, and if it is really annihilated, he feels very pity. But Qin Shuai said don't be impatient, he will come up with a way to solve this matter, he arranged for some robots to be in the intelligence department, but these robots have a self-detonation system, if someone attacks them, then that person will also be attacked in the same way, in other words, it is the power of counterattack.

In response to the aliens' biological attack, they mainly placed some things in the water and soil, so Qin Shuai and the others first tested how many toxins the aliens put in the water, and then tested them in the land.

When they were in the water, they found a strange black box, but it was not a black box, nor was it something dropped by a previous airliner, and they searched hard and found that this thing was decades old. It was salvaged and handed over to the experts of the headquarters of the Union Army for study, and then some communication methods of the crashed passenger plane were found near the nearby mountains, among which there were also some research reports of experts, which were not damaged, which made people feel very surprised, but they were packed in a special suitcase, so this suitcase should be a well-made anti-loss device, so these things were also handed over to the headquarters of the Union Army.

And Qin Shuai and the others arranged an experimental site, and put the robot inspection they did was not too qualified in the experimental site, even if the aliens came to attack, they could only attack this batch of not very sophisticated ones, and they also saved them from dismantling and redoing it. It's just a pity that some of the materials are available, but they can also gain knowledge of some of the weapons of the alien attack robots.

With the arrival of the black pressure alien flying machine, they opened more than 10 attack flight devices, this time they did not have any sense of harmony, but directly fired countless shells at their experimental base, hitting the ground, showing a crater, as expected, these robot people were all destroyed, they were extremely excited, they felt that this time they had done a great job, and they went back to deal with the above.

But they didn't know that Qin Shuai had arranged all kinds of navigation records, as well as monitoring equipment, and filmed them when their bullets and shells were fired, and carried out slow and other analysis, and then analyzed their models. And some of these models have anti-phagogy power, and when this bullet hits them, they will quickly analyze the composition of this bullet and then fuse it, so when the bullet falls to the ground, these bullets have been fused into a weapon that can defend against them.

Qin Shuai arranged for his assistant to go over there and get the videotape, as well as the fused bullets, and came back for research, and studied the first batch of missile navigation systems against the enemy.

With this information obtained, Qin Shuai and several experts from the Alliance Army Headquarters entered the military conference room to discuss, and then invited some non-commissioned officers and soldiers to have a meeting together.

He made a written record of the aliens' bullet attack system, and then showed everyone the pictures they took at the scene, because since these things can have a knock-on effect in their experimental field, they must be using no ordinary bullets.

Qin Shuai started with the basic principle of bullets, and then told them about this complex bullet.

"Bullets are weapons fired from firearms, and in wartime they are one of the easiest tools to kill an enemy or destroy materiel. It is a product of physics, chemistry, materials science, aerodynamics and technology. ”

A few creeps found a new harvest in the experiment, they found that the previous thorn ball was the kind of toxin that existed, they carefully packed it in a bag and took it back, and found some golden bullets with some special holes on them, which were different from normal bullets.

Qin Chuan said: "...... It seems that this time the aliens should be using a smokeless gunpowder, and I'm afraid that in the second attack, they will use it, you see what their bullets do. The attack they used this time may have been a serial attack. ”

Qin Shuai said seriously: "However, according to my observation, the alien is extremely cunning this time, he actually used some of the weapons and equipment of our earthlings to improve it, and then attacked, I am afraid that it is to beware of us to understand some of their attack information, but they need some protective measures, so I analyzed it from their protective measures...... No matter what style and shape of bullet it is, it is composed of four parts: a projectile, a cartridge case, a propellant and a fire cap. For this alien attack, no matter what the bullet is used for, most of the general propellants are smokeless powder. The main ingredient of the gunpowder they placed was nitrocellulose, and the guns were mostly single-base drugs. There are different requirements for different firearms and ammunition. They've just turned some of the bullets into high-level, but basically the principle hasn't changed. ”

He added: "The primer they used this time was made up of a fire transfer hole, a fire anvil and a firing agent. The function is to produce a flame when fired, and ignite the propellant quickly and reliably. …… When fired, the firing agent is ignited by the impact of the firing needle and the fire anvil, and the flame ignites the propellant through the fire transfer hole. When fired, the firing pin fires the primer. The primer burns rapidly and ignites the propellant in the cartridge case, and the propellant produces instantaneous ignition, and at the same time produces high temperature and high pressure, extruding the projectile warhead from the cartridge, and the projectile moves forward under the impetus of the high pressure generated by the propellant, and is squeezed by the rifling, resulting in rotation, and finally being pushed out of the chamber ......"

Qin Chuan said angrily: "Then someone must have shown them our machinery, otherwise, how would he know how our guns and ammunition were used, and then do it so vividly, isn't this obviously copied from our alliance army?" ”

Qin Shuai said: "So today I think it is necessary to hold this meeting, those undercover agents have not been completely disposed of before, and they need to be asked again, they have undergone special training, so they cannot be tortured." ”
