PS. Present today's update, by the way, pull a vote for the "starting point" 515 fan festival, everyone has 8 votes, and the vote will also give the starting point coin, kneel and beg everyone to support and appreciate!

Early the next morning, a group of soldiers were ushered in outside the military camp outside Jinzhou City, and it was Sun Chuanfang and his party, who first reported the good news to Wang Bin after suppressing the popular uprising, and then began to rush back to Jinzhou with his team.

Finally arrived at the barracks the next morning, and after Sun Chuanfang and the others returned to the barracks, someone notified Wang Bin as soon as possible.

Wang Bin knew as early as yesterday that if there was no accident, Sun Chuanfang and the others should come back today, so Wang Bin spent it in the barracks yesterday, so he greeted Sun Chuanfang and the others as soon as possible.

So Wang Bin, who was still asleep, was immediately disturbed by the guards and woke up, to be honest, although Wang Bin had told the guards before that he would wake him up once Sun Chuanfang and the others came back, but it was a little afraid for the guards to really do this, but what if they didn't dare, this guard still gritted his teeth and woke up Wang Bin.

And Wang Bin didn't lose his temper as the guards thought after being woken up, but immediately got up and simply washed up, for the previous guards called themselves out of the dreamland, although Wang Bin didn't want to leave from the dreamland but still forced up, who let himself tell him to wake up once Sun Chuanfang and the others came back, even though he had begun to move towards the sea of stars in his dream, but he still had to get up!

After washing, Wang Bin immediately went to the office, and as soon as he entered the office, Wang Bin saw Sun Chuanfang, Liu Wangzhen and Chen Dongsheng sitting in the office.

As soon as Wang Bin came in, the three people immediately stood up, facing the three people, Wang Bin immediately motioned for the three of them to sit down, and also said as he sat down

"You've done a good job this time, and you haven't lost my reputation as the Fifth Town."

Wang Bin's praise obviously made Sun Chuanfang and the others a little happy, after all, it was a great honor to be praised by Shangguan.

After the three of them finished speaking, Wang Bin spoke again

"The official guessed yesterday that the three of you should arrive today, and sure enough, the three of you arrived this morning."

As soon as Wang Bin finished saying this, Sun Chuanfang and the others thought in their hearts: It's better to be an adult in your own family, and you got up early in the morning to greet us and others.

Then the three of them all said that doing things for adults was what their subordinates should do, and Wang Bin corrected what Sun Chuanfang said a little, and said, "It's not for the official, but for the court." ”

After finishing speaking, Wang Bin looked at Sun Chuanfang and the others, and saw that their expressions were more or less tired, although they were still holding on, but the feeling of exhaustion could indeed be concealed by holding on.

After seeing the expressions of the three of them, Wang Bin also thought in his heart: Why didn't he think of this? How can you not get tired without rest in the middle of this long march?

I was really a little anxious, so let the three of them go back and rest first and then talk about this matter.

So then Wang Bin motioned to Sun Chuanfang and the three of them to go back and rest for a while if they hadn't slept all night, and then go to their house at noon to catch the wind and wash the dust for them.

At this time, Sun Chuanfang and the others really felt a little unbearable, after all, this overnight journey was not a joke, especially to prevent accidents along the way, so it was extremely exhausting.

Especially now, when you need to think, you need to consume energy, so after Wang Bi said that the three of them should go back to rest first, Sun Chuanfang and the others just hurriedly thanked them and immediately left Wang Bin's office.

After Sun Chuanfang and others left the office, Wang Bin sent the guards back to the house and instructed them to receive some officers in the house at noon, and after the guards received Wang Bin's order, Wang Bin himself was still in the office to give instructions on some official documents on the table, although it was said that he was instructing the official documents, but Wang Bin's mind had long been unaware of where it had gone.

Since listening to Liu Wangzhen's idea of smoke weapons, Wang Bin has been thinking about smoke bombs while giving instructions on official documents, and Wang Bin's understanding of smoke bombs is limited to creating visual obstacles to the enemy, if it is used well, it will be of great help to attack the enemy, and it can also be used to defend and delay time. This creates psychological fear and obstacles in sight to the enemy.

Moreover, the main feature of smoke grenades is that the smoke is short, and the smoke is kept for a long time, so as to achieve a real hidden effect, and the most important thing is that it is harmless to the human body and is a non-lethal weapon.

Wang Bin still vaguely remembers that the first appearance of the smoke screen seems to be during the First World War, when the British Navy used aircraft to drop smoke screens containing SnCl4 (tin tetrachloride) and SiCl4 (tetrachlorosilane) to its warships, thus cleverly hiding the warships and avoiding bombing by enemy aircraft.

In modern times, some new military tanks use smoke bombs that can not only conceal the physical appearance, but also have the function of evading infrared lasers and microwaves, so as to achieve real "stealth".

But in this day and age, it is difficult to invent smoke bombs on your own.

In fact, to put it simply, this smoke grenade is nothing more than the use of some chemical reactions to make it.

This smoke grenade is mainly composed of a fuse, a cartridge case, a smoke agent, and an explosive tube.

Generally speaking, smoke bombs mainly rely on their fuming agents, generally using substances such as white phosphorus, tin tetrachloride (SnCl4), titanium tetrachloride (TiCl4) or sulfur trioxide.

When the smoke grenade is fired into the target area, the fuse will detonate the explosive in the explosive tube, so that the shell will explode, and then the white phosphorus of the smoke agent will be thrown into the air, and the white phosphorus will immediately burn itself as soon as it encounters the air, constantly producing billowing smoke.

If multiple bullets are fired in unison, they will form a "wall of smoke" that will block the enemy's sight and create favorable fighters for their own troops.

In chemistry, "smoke" is composed of solid particles, "fog" is composed of small droplets, and the principle of smoke bombs is to cause a wide range of chemical smoke in the air through chemical reactions, for example, after the smoke bomb loaded with white phosphorus is detonated, white phosphorus quickly burns in the air.

Although this principle seems to be very simple, if it had been proposed in advance in this era, Wang Bin himself would not have known whether he would be able to make smoke bombs.

Therefore, Wang Bin simply wrote down some of his understanding of smoke bombs on a piece of paper, such as smoke bombs need to have a smoke agent, which will detonate and ignite after being thrown, resulting in a large number of smoke screens.

Among them, the most important thing is that Wang Bin proposed the fuming agent, but Wang Bin himself is not too clear about these fuming agents, but only proposed several that he knows, such as tin tetrachloride, tetrachlorosilane and white phosphorus.

As for the rest of the questions about how to make it, Wang Bin was ready to leave it directly to Sergei and his engineers to worry about.

So Wang Bin said to do it, and immediately took some of the things he wrote to the arsenal outside the city.

[It's about to be 515, I hope to continue to hit the 515 red envelope list, and the red envelope rain will be able to give back to readers and promotional works on May 15. A piece is also love, and it must be better! 】
