"Yes, you might say that small-caliber bullets make bullets less powerful, no, that's a mistake you're walking into. Small-caliber bullets may have disadvantages such as low accuracy and insufficient kinetic energy at long distances, which makes the effect of hitting heavily protected targets and objects poor, but rifles are not used to fight tanks and armored vehicles, nor are they used to destroy the opponent's fortifications, and its main role is to kill people. Liu Lang bared his teeth and smiled, and the white teeth that were exposed made the future engineers feel a chill in their hearts for no reason.

The one in front of them is a terrifying guy who kills people without counting, if you talk about killing, this one who has a record of killing more than 20,000 enemies in World War I is one of the few in the country! He said that he was a good guy who killed people, so he was naturally a good guy who killed people.

I saw Liu Lang slowly exhale a puff of smoke and continued: "Small-caliber ammunition has a better effect on unprotected or lightly protected living targets at close range, and the recoil of the firearm is smaller, which is convenient for improving accuracy, and the ammunition carrying capacity is relatively large. This is also the reason why the little devil chose the 6.5mm Tomosaka bullet as the standard ammunition for the rifle machine gun. If you choose large-caliber bullets, the power seems to be sufficient on the surface, but the large-mass bullets will sacrifice muzzle velocity, reduce the effective range, and reduce the amount of carrying, increasing the logistical burden, which is also what our independent regiment deeply realized in this battle of the Great Wall.

And, more importantly, who said that the 6.5mm bullets of the little devils are not powerful? I can tell you that I have at least ten ways to make this bullet more powerful than a 7.6mm bullet. ”

Liu Lang said as he took out a few 6.5mm bullets from his pocket and threw them on the table, and continued: "If I rename this round-headed bullet to ensure ballistic stability as a pointed head, and separate the core from the armor, can any of you tell me what the consequences will be if it hits the human body." ”

After a short silence, it was the seemingly shy "Su Xiaomei" who said with a shocked face: "Then this kind of bullet will explode after being hit strongly, what 。。。。。 ”

Without waiting for him to elaborate, anyone knows what the consequences of being shot by such an exploding bullet are.

"Hehe, I can also design the armor to be thick in the front and thin in the back, with a straight trajectory at a distance of tens of meters, but when the bullet is tens of meters away, it will roll, and if it hits the human body, it will tear human tissue in a large area, forming a huge wound."

"I can also throw a little lead on the pointed part of the warhead, it will not destroy the overall aerodynamic performance of the warhead, it only needs to leave the lead in the body after it enters the human body。。。。。" Liu Lang said with a sneer.

In front of a group of future scientific and technological elites who have not yet learned what cruelty is and only have blood, Liu Lang interprets the cruelty of the enemy to the extreme, and any little change can turn every small bullet into a demonic bloody mouth. Everyone can imagine that being hit by such a bullet, even if it misses the vital point, is definitely worse than death.

As if it was not enough, Liu Lang continued: "We are making progress, and the Japanese will not be idle, although I have never stopped disliking them, but they have never stopped their own pace of progress is also worth learning from, they have experienced the battle of Songhu and the Great Wall of our country, they will definitely improve their bullets that show all kinds of deficiencies, and the three methods I just mentioned are definitely the one they will choose." ”

Liu Lang's words are not untargeted, in the past time and space, after the Great Wall battle, the Japanese army improved the 6.5 mm round-headed bullet with insufficient lethality. IN FACT, ACCORDING TO RECORDS, THE JAPANESE ARMY USED THREE KINDS OF 6.5MM BULLETS IN A FULL-SCALE WAR, EACH WITH DIFFERENT FUNCTIONS, ONE OF WHICH WAS THE SEPARATION OF BULLETS AND ARMOR FIRST PROPOSED BY LIU LANG. Liu Lang's old man was extremely disdainful of the Japanese gunshots often mentioned in the TV series, and the soldiers of our army who were shot were shot twice, as long as they were not critical, they were still fighting bravely like no one with a gun.

Such a situation is not unfounded, but it definitely does not appear in regular combat. Only when the security forces equipped with the early round-headed bullets of the Japanese army and the guerrillas who were accustomed to close combat would this situation occur, as for the regular combat, the Japanese army has long been fully equipped with improved pointed bullets, and the veterans are most afraid of being bitten by this kind of bullet, and the wound the size of a teacup can definitely make life worse than death.

"Moreover, is it possible that because of the general use of Japanese 6.5mm ammunition, we can capture Japanese ammunition as a supplement?" "Su Xiaomei", who seemed to be a little timid, didn't seem to be frightened by this cruel modification, but her eyes lit up, adding.

"That's right, if we lose the frontal battlefield, we may be forced to go behind enemy lines and continue to fight, and without provisions, we can only live by robbing him of a dog's day." Liu Lang glanced approvingly at this baby fat with a unique vision, and said with a smile.

"Like the Storm rocket artillery, pistols and rifles will be approved first, and Professor Ye will designate the project leader, and then recruit top metallurgical and mechanical manufacturing experts from China to develop and develop, in addition to rocket artillery, Dr. Grunov also needs to participate, and I will send someone to you as soon as possible, and all the expenses and equipment required are docked with Director Liang Wenzhong. And, when I come back from Europe and the United States, there will be more projects waiting for you, squad light machine guns, submachine guns, shotguns, air explosive fuses, bottom row extended-range gunpowder, more powerful explosives, we will gradually have because of you. Liu Lang smiled and looked at the future scientific and technological elites who quickly recorded every new term they said with a pen.

The things he said are all technologies that have emerged in this global war, which can be made by Westerners, and will not be able to be done by these highest-ranking scientists of the future republic who already have guiding ideas and principles? They will.

"To be honest, I don't know why Liu Lang is so confident in me, you know, our group of physics and mechanics have just transferred to the field of ordnance research, and many of the terms you said have never even been heard." Ye Qisun stopped the pen in his hand and looked at Liu Lang with a wry smile on his face and said.

"Haha, Professor Ye, I want to say that you and the students you supervised will surely go down in history and become the most shining group of people in the history of Chinese science in this century, you may not believe it. However, you and they are already the group of people with the most majestic knowledge of the Chinese nation, who else can I trust except you? I, Liu Lang, am a martial artist, and I only know how to lead soldiers to fight and defend the country, but I hope that the soldiers under my command are not because their weapons are inferior to others, and they are sad and helpless to fall under the enemy's artillery fire and guns, even if we want to die, we will die on the way to charge, and before closing our eyes, we see the corpse of the Japanese criminal. ”

Liu Lang stood up and looked at everyone present, his eyes were different, "I remember a great man once said a famous saying: study for the rise of China. Now, it is time for you scholars to make your own contribution to the survival of China. ”

"Well said, a good sentence to read for the rise of China, now is indeed the time for us to do something for this country and nation." Ye Qisun also stood up excitedly and responded loudly. "It's still the same sentence, without him, my generation should just do my best."

The two looked at each other and smiled across the conference table, and a group of young scientists stood with bright eyes but passionate emotions.

This scene will always stop in the mind of the youngest "Su Xiaomei" who is still a little juvenile and childish.

Years later, whenever she thinks of this moment, her blood is still boiling.

As she said, at that moment, she felt that if Captain Liu said that she could do it, then she would definitely do it.

Of course she can, much better than Liu Lang, who doesn't know her future achievements, imagined.

Because, she is not surnamed Su, she is called "Su Xiaomei", because her mother is from a beautiful girl in Suzhou, and she has the word "Su" in her accent with some Wu Nong's soft words.

In the past, the doctoral major she studied in time and space was also a ballistic major that was extremely secret in the military industry of the Third Reich, and her dream that day was also to enter the Nanjing Ordnance Industry Bureau to manufacture weapons to defend her family and country.

Liu Lang helped her achieve it ahead of schedule.
