Zhao Bu took "Lao Pei" back to Crouching Tiger City from the desert in the Northland a few days ago.

Pei Yuanshao didn't expect that he would accompany the "Little Fire Dragon" to the north for a walk around and come back. turned out to be the head of the Crouching Tiger Training Corps. Although he has always been honest and satisfied with serving as the commander of the Heavy Infantry Division of the Crouching Tiger Army, it does not mean that he is not self-motivated.

As the core of the three major training regiments, the total number of troops of the Crouching Tiger Training Corps can sometimes reach an astonishing 40,000 people, which is quite equal to the number of the Crouching Tiger Army! Zhao Xing asked Pei Yuanshao to carry this heavy burden, but he was sad.

But fortunately, Pei Yuanshao had a demon-like guy by his side to help him come up with ideas, and Zhao Bu suggested that while following Gao Shun's already formed training ideas, he might as well use his brains to train a unit that specializes in the use of various firearms. Pei Yuanshao thought about it, since it was very difficult to seek a breakthrough in the traditional training field, why didn't he use the help of the "Little Fire Dragon" to train a group of troops who were proficient in the use of firearms for Zhao Xing!

Pei Yuanshao didn't expect that he had just had an idea under the inspiration of Zhao Bu, and the Crouching Tiger Training Group came to "business".

It was none other than Pang Tong and Li Jinwu. One of these two people is the second-in-command of the Bingzhou Army, and the other is the leader of the Crouching Tiger Army, and they are usually very familiar with Pei Yuanshao, and they all shout "Old Pei" when they open and close their mouths.

Li Jinwu put his arm around Pei Yuanshao's shoulders and said enthusiastically: "Old Pei Wow, congratulations to my brother on your promotion to such a prominent position as the head of the training regiment, let's go and pick up a table on the Heavenly Pavilion to celebrate your achievements!"

Pei Yuanshao was not stupid, he shook his head like a drum, and said: "Don't, big brother of the Li family, your wine is probably not so delicious! The lord taught us: 'It's okay to be courteous, it's either a traitor or a thief', you still explain your intentions, let's drink again." ”

It just so happened that Pei Yuanshao's daughter-in-law Li came in to deliver tea and fruit snacks to the two distinguished guests, and when she heard Pei Yuanshao being nonsense there, she glared at him, and then said: "You fool, what are you talking nonsense, the eldest brother of the Li family has grown up since I was a child, where is there a treacherous person!

Pei Yuanshao was reprimanded by his daughter-in-law, but he was not angry at all, he just smirked "hehe", he was not really stupid in his heart, but he never had any temper in front of his daughter-in-law.

Zhao Xing told him about this family business back then, and Lao Pei was grateful in his heart. Although Li was already a widow at that time, she was young and dignified, and she knew that she loved men, and she cooked good food. Pei Yuanshao has lived a happy life since welcoming the Li family into the door, and the husband and wife have been married for so many years, but they have never quarreled, and their love is like honey blending oil.

After Li Shi withdrew from the living room, Pang Tong said: "Old Pei, we are really a little busy this time and want you to help." However, if you help with this favor, it is destined not to suffer, and it will be of great benefit to you, the head of the training group!"

Pei Yuanshao heard that it was good for him, his eyes lit up, and he said: "Let's just say it directly, my old Pei is a rough person, but he also understands some things, since it is related to the training regiment, it is related to the war, it doesn't matter if I personally have any benefits, but I must not let my brothers suffer!"

Li Jinwu then said: "We would like to ask the training regiment to help the Crouching Tiger Army urgently train a group of elite soldiers who can skillfully use new firearms, and it is best to complete it within half a month, we have urgent needs." ”

Pei Yuanshao nodded and said truthfully: "The training group does have this consideration, since you are the first to speak, then protect the Crouching Tiger Army first." However, how to train, we have to listen to Zhao Bu's opinion, after all, many new firearms are designed and produced by him himself, and he has the most right to speak. ”

"Hey, what about Zhao Bu's rabbit cub? I haven't seen him when I came over today!" Li Jinwu was reminded by Pei Yuanshao, but he remembered Zhao Bu. According to the seniority, Zhao Xing and Li Jinwu are old cousins of bone and blood, and Zhao Bu is Zhao Xing's son, so Li Jinwu has to shout "uncle", so Li Jinwu calls Zhao Bu "rabbit cub" It is not abrupt and rude.

After Zuo Lin came back from the north, he plunged into the equipment research institute and did not return home for several days. Listening to his tone, it seems that he has solved several technical problems of the 'swarm', and is now busy finalizing it. Pei Yuanshao explained to Li Jinwu and Pang Tong.

Li Jinwu asked in surprise: "What kind of strange thing is this?"

"Hehe, I want to know what a swarm of bees is, tomorrow I will invite my uncle to eat barbecue on the training regiment's large school field, and you will know when the time comes!" Zhao Bu, who had just come back from outside, said to Li Jinwu with a wicked smile.

At noon the next day, Zhao Xing, Li Jinwu, Pang Tong and others quietly came to the huge training ground of nearly 10,000 mu opened up by the Crouching Tiger Training Corps outside the city, and quietly waited for the surprise brought by the "little fire dragon" Zhao Bu.

The idea of "a swarm of bees" was Zhao Xing's order for Zhao Bu, so he knew about this kind of hot weapon that could be launched in a cluster manner, but he was also very much looking forward to whether this big killing weapon that Zhao Bu had put out could be comparable to the "swarm of bees" used in the army in the Ming Dynasty in later generations.

Everyone sat on a higher observation platform, and there were really a few barbecue charcoal troughs in front of them, and Zhao Buzheng was carefully sprinkling pepper and cumin and other spices on the smoking mutton skewers on the barbecue, to see that the craft was actually the true inheritance of Zhao Xing.

"Xiao Bu Wow, when will I let my uncle see which swarm of bees you have!" Li Jinwu urged Zhao Bu a little anxiously, but he had eaten enough roasting, and this thing was not very rare at all.

"Hehe, uncle, don't worry, you think of this meat skewer as the fierce man Zhang Fei, and when a swarm of bees flies out, Zhang Fei will become a black skewer on a bamboo skewer!

Pei Yuanshao, who was in charge of directing the launch at the scene, saw the communication fireworks rising into the air in the distance, so he ordered: "Ignite!"

Subsequently, dozens of devices resembling the Katyusha of the later Soviet multiple rocket launchers, and at the same time, smoke came out from the back of the fart/strand, and the gunpowder sealed in the launch chamber instantly generated a huge punch, spraying out the crossbow arrows blocked above the muzzle like a swarm.

In the blink of an eye, a black rain of arrows whistled through the sky not far in front of the stands, shooting a bunch of straw men on the other side into hedgehogs.

Before the stunned few people came back to their senses, Zhao Bu ordered the herald to light the communication fireworks for the second time.

Zhao Bu said lightly: "The swarm of bees launched in the first round was used to kill and injure ground troops in a large area. This next second round of launches, but I specially designed for Zhang Fei, I heard that he is very white, it seems to be whiter than his father, this time he must be blackened!"

Zhao Xing listened to Zhao Bu's comparison with Zhang Fei's face, and immediately rolled his eyes, and then turned his head to look at the sky in front of him......

PS: I would like to express my sincere thanks to a professional book friend, this is the information on the working principles of some firearms that he specially provided for Nandao, and sent it to share with the book friends!

The essence of Katyusha is rockets. Everyone knows the appearance.

The "swarm of bees" is a Ming Dynasty product, and its form is a cluster launch tube, each tube is loaded separately, and the arrow shaft is shorter than a bow and arrow, more like a crossbow arrow. There is a combustible material behind the arrow to close the lumen, and all the propellants at the bottom of the tube are interconnected, and a large amount of gas is instantly generated after ignition, and all the loads are ejected. Of course, it is also possible to fire incendiary bombs with fusiform fixed wind wings, which saves the lumen sealant.

The propulsion method of a swarm is more like a gun grenade, all the propellants are used to produce the maximum initial velocity, and there is no power to provide the rocket body when it is discharged; the rocket requires continuous advancement, and 1/3 to 1/2 of the propulsion part of its stroke is burning and ejecting, which requires the propellant to be different from the composition of the warhead explosive, low nitrate and high carbon, and the particles should be larger, so that it can continue to burn instead of exploding.

Only with a long enough slide rail can make the arrow body get a fixed course distance, the course after take-off depends on the tail, such as the tail to do a little tilt can make the rocket body rotate, obtain a stable course, reduce the scattering surface.
