c4 is a plastic explosive similar to dough. It consists of strong drugs and adhesives, plasticizers and labeling agents. In the base, strong drugs are cyclones with a content of 91% and the labeling agent is ordinary dinitrobutane. In addition, some plasticizers are added, that is, quinolic acid, etc. Of course, an object that can be used as an inner tube is essential, that is polyheptene, which was produced by the butyl rubber factory established by the exxon company the year before. In addition, several other chemical raw materials are also transported from the United States, including cyclone drugs.

Looking at the only dozen barrels of chemical raw materials, Zhao Hu couldn't help but frown secretly. It seemed that ordinary materials could not be made without solid industry. Take the extremely ordinary methanol as an example. If the base wants to produce it, it doesn't know how much coal tar it needs to distillate. Moreover, it is impossible to obtain pure products without purifying the distillation tower.

Take polyphenylene as an example. The molecular weight of this thing is really huge, at least 20,000 yuan. If mixed with a drug, a large amount of nitrogen-containing and carbon-containing compounds can be released within one second, and the detonation speed is 8,000 meters per second. In other words, within one second, all explosions can be completed, and no one can escape from this explosion.

Of course, the whirlwind medicine Zhao Hu can also be made, but it is not cost-effective. Once, when others produce, various chemical raw materials can be bought directly. The base, whether it is methanol, formaldehyde or umortropine, has to be produced one by one. It is not only time-consuming and labor-intensive, but also has extremely low output. More importantly, without the guarantee of various safety equipment, this kind of production is extremely dangerous, and there is a risk of explosion if you are not careful!

The inability to produce industrially does not mean that it cannot be produced in the laboratory. For this reason, Zhao Hu specially asked the transportation team to buy expensive glass instruments and equipment from Shanghai, and then grabbed a few chemistry students from the base, allowing them to develop and experiment according to the purchased materials. They do not ask for much production, but at least they must master the production methods and prepare for future industrial outbreaks.

Here, he also used various bottles and jars to make a long time before kneading a large piece of white dough like a kneading dough.

He carefully broke off a small piece, put it on the stone slab, then ran away from a distance, pulled the rope, and the iron block hanging on it suddenly fell. With a "defying", it's okay!

I broke up another piece and threw it into the stove, but the flames increased a little, and there were no abnormalities such as explosions, which meant that the experiment was very successful.

Finally, the guy found a large water tank and threw the dough filled with the detonator into the water. Several junior college students behind him were not concerned about Zhao Hu's warning and still gathered together to talk and laugh. Zhao Hu found that everyone was still far away, so he did not remind him, but suddenly pressed the explosion device.

"boom!"

"Boom boom boom!"

The explosion was extremely violent. Of course, the first shot exploded in front of you. A large cloud of water mist splashed around with broken tank fragments, which scared several guys so much that they all shrank under the low wall. Unfortunately, they could resist the fragments and the water curtains. Everyone was soaked all over, and no one dared to look up.

The explosion continued. From the second sound, Zhao Hu felt something was wrong, because the sound was from his own, but later he went to the distance. Not far ahead, a ball of black smoke rose from the ground, and then gathered into a black smoke ball, slowly rolling around!

"Raid! Fast forward the air raid shelter!"

When several engineering students heard this, they rolled and crawled into the air-raid shelter behind them. When Zhao Hu also squeezed in, another person ran out of the hole and shouted from afar: "Didn't you notify me of not going out soon? Why do you think it's like a wind in your ears?"

When Zhao Hu saw that he was from the security department, he quickly smiled and said, "It's been fine for a few days. Everyone is so idle. It just so happened that my new weapon test was successful, so he took them out and tried it."

"That cannot violate the established discipline, after all, this is related to everyone's life safety!"

In the huge noise, Zhao Hu also yelled: "No one can violate it in the future. By the way, what happened to the bombing ahead?"

"Don't you see it anymore? The Japanese are bombing our fake positions, so our arsenal is very safe. Deputy Director Zhao, your idea is amazing!"

Zhao Hu and the others had not heard the roar of the plane before because the explosion of the water tank was too violent and the sound of their ears was buzzing. In addition, the Japanese plane was very fast. Not long after the warning was issued on the island, they had arrived above the island and did not circulate. They pressed down and were like a bomb, blowing up the fake fortifications that had just been built, causing dust to spread and smoke!

The first wave of bombing was very successful. Shirakawa Ichiro, who stayed in the sky to observe, smiled: "Yo Xi, the insight of the upper peak is indeed extremely Minrui. If he hadn't been persistent and thought about it, we would have regarded the pile of newly built wooden racks as an important stronghold for the enemy!"

Shirakawa's judgment is well-founded, because the fire below was burning very strong, and the rolled black dragon was no different from the lit oil depot. If this was still wrong, he would rather dive into the water and never float up again!

Zhao Hu was also running hard against the black smoke, cursing these prodigal sons in his heart. Is it easy to collect some waste tar? With all kinds of industrial waste, can we avoid black smoke? Of course, this cannot be blamed on Lao Shen. After all, he was not born in engineering and did not know the reasons for saving waste, so he just burned the waste at one time.

Of course, you can ignore what you burn, but now you are in the limelight. You are moving forward with smoke from the wind, and you may have only the teeth and whites on your face!

As soon as I rushed to the fake base, I saw Xiao Yu jumping: "Forget it, the wave just now, after all, we don't have an air defense alarm, so we can only rely on manual observation, but the time you arrive at the gun position is too slow. If you continue like this, let alone the plane, you can't even get a single hair!"

Just as Zhao Hu ran outside the artillery position, four other enemy planes in the sky also began to circumn and dive. Outside the artillery position, someone shouted from afar: "This is the artillery position, and idlers are not allowed to approach. Hey, isn't this Deputy Director Zhao? Why is your face dark like a carbon ball?"

Zhao Hu ignored him and quickly ran to Erqi's cannon position. He pulled down the gunner who was about to aim, and personally started to shake it. He shouted: "Everyone, aim quickly, the enemy plane is here!"

The four enemy planes plunged their heads without making adjustments, and then started to form a group at an altitude of two thousand meters. Then, one after another, launched a second strong attack on the fake base where the fire was strong!

Due to smoke blocking the other two gun positions, they could not see any situation in the sky for a while. Only Zhao Hu was in the limelight and could command several other anti-aircraft guns.

The four bombers had the previous sweetness and knew that there were no air defense weapons below, so they seemed even more unscrupulous. They didn't even look around and aimed at another small highland, preparing to blow it into a sea of ​​fire.

It's close, it's close, five thousand, three thousand, one thousand, you can drop bombs!

The bomb thrower pulled the wrench from behind, and two large winter melon-like bombs left the body and quickly fell down with a swiftly rotating tail wing.

"Boom boom boom"

Another ball of fire was shining. Shirakawa pulled up his fuselage and looked back at the suspicious place where he was blown to death. He couldn't help but smile: "Hmph, the Eighth Route Army is the Eighth Route Army, and there are no anti-aircraft guns. You can't let me bomb?"

Suddenly, a fire broke out in front of the fuselage. Immediately afterwards, I felt my plane tremble. After a crackling sound, there were a dozen holes suddenly!

"I'm shot, the enemy attacks!"

"I've been shot, so I'm asking for support,"
Chapter completed!
