The development of explosives has gone through four stages. At present, the internationally popular saying is that the propagation speed of the detonation waves during explosives is divided into four generations.

The first generation of explosives was "nitroglycerin" discovered by Nobel. The second generation of explosives was trinitrotoluene, which played a great role in World War II (codenamed as a strong explosive synthesized by artificial organically. Its explosive ability is strong and its properties are stable. It can be used for intensive fire shooting of machine artillery, which greatly improved the cruelty of the war and is still widely used until now.

The third-generation explosive Black Sorkin was born after World War II. Its detonation speed reached meters per second, and was used for the large-scale suppression and strikes of multiple rocket heavy artillery, which can greatly improve the power and range of weapons; secondly, Oktokin, whose detonation speed reached 9,000 meters per second, has a slightly higher impact sensitivity than TNT, is easy to detonate, has better stability, and has high comprehensive performance. In the Gulf War, it was used for non-contact asymmetric combat of long-range rocket missiles.

cl—20” explosive is currently known to be the most powerful and powerful non-nuclear elemental explosive that can be used in practice.

This new type of explosive, with a detonation speed of up to 9,500 meters per second, is known as the "fourth generation explosive" and is also known as the "breakthrough energy-containing material". It is an epoch-making new high-explosive military explosive and is well-known in the world's fire explosives academic community.

The energy of cl-20 is 1.8 times the tnt equivalent. The most blunt understanding is that the explosion energy of one kilogram of cl-20 is equivalent to the power of a 100 kilogram of tnt explosion.

The above is an excerpt from the information)

In this high-energy explosive, it can only be produced in the laboratory and has not yet formed the ability to produce industrially. In the future dream, it was not until 2015 that the engineering production was completed in China and won the 2015 National Defense Science and Technology Progress Award."

If you are kidding in the future, don’t joke about such things!" Zhao Xiangbei almost broke out in cold sweat. Fortunately, it was just a name, not a military secret, otherwise there would be trouble again."

Tell, it's not the most powerful!" Guo Tailai muttered in a low voice, no longer talking about this question.

After chatting for a few words, Guo Tailai specifically asked about her senior sister's situation. After knowing that everything was fine, she didn't stay for a long time and said goodbye. Of course, before leaving, she specially asked Director Zhao what Mr. Ding liked the most. Although she had prepared a pair of combat boots, for the beautiful Mr. Ding, this was only a supportive heart, and it was best to choose what she liked.

"Fuck Yan Yan!" Zhao Xiangbei pondered for a while, and finally said: "Actually, she still likes some beautiful jewelry. I haven't given her to her in the past few years, alas!"

"Received!" Guo Tailai understood in seconds, patted his chest and said, "I promise to satisfy Aunt Ding!"

"Get out!" Zhao Xiangbei always felt something was wrong, but he didn't think about the smell for a while. Seeing Guo Tailai sitting in front of him, he planned to give his wife jewelry, but only gave him a pair of shoes, he couldn't help but get irritated: "Don't be upset in front of me!"

Guo Tailai immediately obediently walked away and disappeared quickly."

Sister Wu, do you sell jewelry that sells 1,000 gold in your store?" After leaving Zhao Xiangbei, Guo Tailai called Wu Shanshan. Sister Wu is the general manager of Fuling Gold Store in Beijing. She should always sell gold there, right?

It is definitely not suitable to give diamonds to your prospective mother-in-law. You should use your duty gold, which everyone likes. In addition, Guo Tailai decided to buy a few suitable ones for his mother, so you can't be more favorable than the other!

Of course, there is no problem with Wu Shanshan. She directly invited Guo Tai to her store to see it. As long as Guo Tai comes to see it, it is guaranteed that only the gold price will be charged and no processing fees will be charged.

Tailai drove directly to the address mentioned by Sister Wu. Fortunately, there was no traffic jam. It took only more than half an hour to arrive at Site. There was a counter of Fuling Jinshang in Site, which looked very noble. When Guo Tailai passed by, Sister Wu was waiting there and accompanied him throughout the journey.

Guo Tailai planned to give it to his mother, and Sister Wu enthusiastically recommended the bracelet. Basically, the gold bracelet can be said to be a killing weapon for women of all ages. As long as it is given, no one will dislike it.

Yes, after looking around, Guo Tailai found that he didn't even like any of them. It was either the style was too old or the appearance was average, and there was no such thing that Guo Tai could see in at a glance.

He is not only good at making gold jewelry, but also some gems. However, Guo Tailai didn't even see it, but just shook his head.

"Little brother, what kind of thing do you want?" Wu Shanshan was not annoyed. A master-level handicraft expert like Guo Tailai must have a high vision, so she fully understands it."

I want that kind..." Guo Tailai reached out and gestured: "The exquisite, exquisite workmanship and eye-catching accessories. It is best to be the unique one, or take a step back, it must be the best limited edition style, is there any?"

"There are unique ones, but if you want the best ones, it will be difficult." Wu Shanshan smiled bitterly: "Master handicrafts can't be made in a year. Unfortunately, the last batch was just picked up by someone. Why don't you wait a few months and I'll order two for you?"

"I plan to use it as a gift for the Spring Festival." Guo Tailai also smiled bitterly. If he waited for a few months, it would definitely be too late to go.

"Why would I recommend you to another store?" Wu Shanshan was not upset that Guo Tailai didn't choose anything, but instead suggested enthusiastically: "The capital is so big, there are always something you like."

Forget it, I will do it myself!" Guo Tailai thought about it for a while, thought about some things he saw in his dream in the future, and finally made up his mind and said, "Sister, you sell a thousand yuan here, right? I'll buy a batch and make it myself!"

Do it yourself?" Wu Shanshan was stunned, and then thought of the magical method of Guo Tailai when repairing and maintaining the watch. Suddenly, even Wu Shanshan was a little surprised how amazing it would be if Guo Tailai made it by hand."

Little brother, in this way, I will produce the materials, you will use handmade products, and leave one for the finished product you made for my elder sister. How about it?" Wu Shanshan is also a very smart businessman, and immediately made a decision.

"No!" Guo Tailai hurriedly stopped him. He wanted to give Mr. Ding one, how could he take advantage of it? However, Wu Shanshan was also very frank, and Guo Tailai came up with a thoughtful plan: "In this way, I will buy the materials at the price. I will put one of the things I made here for you to sell them to see the effect."

It was safe, and Wu Shanshan didn't even think much and agreed immediately. She didn't lose any of her losses, and could see Guo Tailai's skills again, killing two birds with one stone.

While Guo Tailai and Wu Shanshan reached an agreement, Zhao Xiangbei finally figured out what was wrong. Guo Tailai, a little bastard, seemed to mutter when he talked back to him, saying that he didn't hear clearly what was specifically, but there must be a problem.

Don't joke about cl-20. Guo Tailai seems to be unwilling to accept it? Why is Guo Tailai not convinced with the highest power of the known high-energy explosive? Does he know that it is even more powerful?
