Bright Sword starts with the grenade flat.

Chapter 102: He who does not plan for eternity cannot plan for a moment.

Liu Xiu looked at his father's disappointed look and explained:

"Dad, don't be discouraged. I believe that the Eighth Route Army will definitely win the final victory. When the time comes, there will definitely be room for your development, and you will definitely successfully develop your explosive engine!"

When Liu Qin heard this, he also said:

"I know that the Eighth Route Army is indeed different from those forces, and I understand the Eighth Route Army's ideals and ambitions, so I chose to join the Eighth Route Army!"

You must know that Liu Qin joining the Eighth Route Army is actually quite fantastic. When Liu Qin was working as a translator for the Little Japs, he relied on his status as a good friend of Hirata Ichiro to often rescue the people in the city who were about to be harmed by the Little Japs or the Second Japs. .

The little Japanese and the second Japanese also let those people go for the sake of Ichiro Hirata. For once, Liu Qin's rescue actually ended up on the Eighth Route Army, and the Eighth Route intelligence officer looked at Liu Qin not like those The two devils or translators who did all the bad things.

So he made his identity clear. Liu Qin had naturally heard of the Eighth Route Army's reputation, so Liu Qin became the Eighth Route Army's undercover agent on the Little Devils' side, facilitating the Eighth Route Army's actions.

·······

Early the next morning, Liu Xiu and Liu Qin set out for the arsenal carrying the barrel of a Type 97 mortar and several shells.

Yes, Liu Xiu still knows the production capacity of the arsenal, so naturally he also knows that they cannot produce seamless steel pipes, and it is easier to directly modify the gun body of the Type 97 mortar into a recoilless rifle than to directly manufacture a recoilless rifle. too much.

Moreover, Liu Xiu has no need for this Type 97 mortar. After all, his second battalion now has twelve Type 92 infantry cannons!

Although this Type 92 infantry gun is a bit heavier than the Type 97 mortar, it has many uses!

Not only can it shoot directly, it can also be used as a mortar, and its range is similar to that of the Type 97 mortar.

Of course, in terms of power, it is smaller than the Type 97 mortar. After all, one has a caliber of 90 mm and the other has a caliber of 70 mm. This also results in the Type 97 mortar having a shell weight of 5.5 kilograms, while the high-explosive shell of the Type 92 infantry gun only weighs 3.5 kilograms.

··········

After Liu Xiu arrived at the arsenal, the director of the arsenal immediately came out with a smile and welcomed him:

"Oh! There are so few visitors! What kind of wind brought Deputy Liu of the Independent Regiment to my place!"

The director of the arsenal and Liu Xiu are old acquaintances. After all, they have known each other for 40 years! Since Liu Xiu changed the grenade into a shoulder-fired grenade, and changed the grenade in the grenade into a shaped armor-piercing projectile, Liu Xiu never came to this arsenal again after he became the regiment commander.

Of course, although Liu Xiu has never been here, news of Liu Xiu's promotion has also spread to the arsenal. The names of the youngest battalion commander and the youngest deputy commander are all Liu Xiu!

Regarding the enthusiasm of the arsenal director, Liu Xiu also smiled and said:

"Of course I'm here to give a gift to the factory director. What do you think of the 97-type mortar? Wouldn't it be exciting if it were changed to a shoulder fire?"

Regarding Liu Xiu's question, the factory director immediately shook his head and said:

"Liu Xiu, your idea is unrealistic. The grenade modification method cannot be used on this mortar. Its caliber is too large. Cotton pads and muzzle brakes cannot suppress such recoil. Unless you want to sacrifice a gunner with one shot!"

When Liu Xiu heard what the factory director said, he naturally nodded and said:

"Director, of course I know what you said, so didn't I invite someone who has a way to solve the recoil of the gun?"

Liu Xiu said this and introduced to the factory director:

"The factory director would like to introduce to you, Liu Qin. Before the war started, he studied abroad with the Japs. He came back after the war started. He used his knowledge of the Japs language to work as an undercover agent. He just ended his undercover career last night. When he was chatting with my dad later He said he had a way to turn a mortar into a cannon that could be fired from the shoulder."

When the factory director heard that Liu Qin was actually an international student, he immediately said: "What a rare visitor. Our arsenal is short of high-tech talents like international students!"

Liu Qin also smiled and shook hands with the factory director and said:

"Director, let's discuss how to improve the mortar! I came up with the drawings last night. Let's go to the office and I will draw the drawings on how to change the mortar into a recoilless rifle!"

When Liu Xiuhe, the factory director, saw his father being so anxious, he immediately went to the office without hesitation.

In the office, Liu Xiu's father explained while drawing drawings:

"The method to eliminate the recoil is very simple, that is, remove the base of the gun barrel and directly let the high-pressure gas from the gunpowder explosion spray backwards, so that the base of the mortar is no longer stressed. Of course, in order to allow the mortar shell to have enough The force moves forward, so there must be a counterweight to block the rear of the gun, so that when the forces between the two are balanced, you don’t have to worry about the mortar shell not being able to fly out!”

Of course, the final issue is the excitation of the mortar. After Liu Qin’s idea, the mortar shells were improved and the bottom excitation was changed to side excitation. That is, a small hole was opened in the barrel and the firing pin was placed. Just come up here.

Liu Xiu looked at the drawings drawn by Liu Qin and asked the factory director:

"How about it, factory director, does our arsenal have the conditions to produce such a thing?"

The factory director looked at the drawings drawn by Liu Qin and said:

"This is not difficult. The most difficult barrel to produce has been replaced by a mortar barrel. The remaining small parts can be easily produced. It would be even easier to use the sand mold casting taught by Liu Xiuyou! "

After Liu Xiu heard this, he nodded with relief, and then continued to say to the factory director:

"By the way, director, the mortar shells also need to be improved! It would be best to have shaped armor-piercing shells. The principle of that thing is also very simple. I believe that the 90mm mortar shells can be modified into The armor-piercing ability of armor-piercing bullets must be very strong!”

However, Liu Xiu's words made the factory director frown and said:

"Deputy Commander Liu, isn't it a bit redundant to have such a strong armor-breaking ability? According to the reports of many comrades who have used shaped energy-breaking armor-piercing projectiles from grenade tubes, using a grenade tube's 50mm-caliber shaped energy-breaking projectiles has Armor-breaking bullets are enough to kill any kind of tanks and armored vehicles of the Japs!"

When Liu Xiu heard this, he just smiled and said:

"Director, although the shaped armor-piercing projectiles fired by our grenades are enough to penetrate the Japanese tanks, do you know the armor thickness of German tanks on the German battlefield and the armor thickness of American tanks? The shaped charge armor-piercing projectiles of our grenade can be used against Japanese tanks, but they cannot be used against German and American tanks!"

"Although this little devil and Deguo are on the same side, can Deguo's tanks still come to us? Will the United States suddenly turn its guns and attack us?"

When Liu Xiu heard this, he just smiled and said nothing. If Liu Xiu was not a time traveler, how could he have imagined that we would have to fight with the United States in less than seven years!

As a time traveler, Liu Xiu naturally has to make plans for the future. After all, if you don't plan for the future, you can't plan for the moment, and if you don't plan for the overall situation, you can't plan for a region!
