On September 1, the Eighth Route Army Headquarters and the 129th Division issued instructions to southern Hebei to strengthen the party's leadership and base construction in the troops.

On September 4, the main force of the 386th Brigade, together with the 687th Regiment of the 115th Division, Zhao Tu Detachment broke the Qing Railway.

The Eighth Route Army who were resting in Linzhang County did not participate in the job of breaking the railway. After all, they were still busy fighting the puppet army, suppressing bandits, and raising equipment.

And in these days, the battle between Wuhan in the south was hot. On the 2nd, the 36th Division, which hurried to the northern foot of the Dabie Mountains, began to block the 11th Division of Ogisu Strength Division, and the 87th and 88th Divisions were assisted.

This battle brought the final sound of the German Armored Division, which was an extremely outstanding battle between the German Armored Division and Japan. There are relevant chapters in the old book, which can be read.

Jiuzhai Arsenal, after all the guerrillas left, the headquarters secret service regiment sent a battalion to station here to help guard the safety of the arsenal.

The headquarters secret service regiment is the headquarters' guard force. It is sent here to a battalion, which means the leaders. It can be seen how high the arsenal is in the minds of the leaders.

Now, the people who run and fuck every day have become elite soldiers of the secret service regiment. Although they are still running on the same road and the people still gather at the entrance of the village to watch the fun, the atmosphere is different.

The villagers all knew that their children had gone to the battlefield to kill the enemy, and their worries were quietly spreading. Looking at the running team, they just hoped to see their children...

The battalion commander who led the team was named Wang. Every day he ran to the front and got together with Hu Changyi. If he didn't know, he thought this was Hu Changyi's guard.

For the sake of this battle experience, Hu Changyi’s guards and correspondents were sent out, and he was definitely a commander-in-law.

"Captain Hu, Director Hu, can you really build 35 heavy machine guns this month?" Battalion Commander Wang asked again.

"Yes! Or did your camp get 6 heavy machine guns as soon as they arrived? Those are all new products from last month!" Hu Changyi said with a smile.

"Okay, you kid is really promising! We used to be guards for the commander and climbed snow-capped mountains and crossed the grassland together. Now... hehe, we are building guns and cannons together!" Battalion Commander Wang and Hu Changyi were very familiar with each other.

"I am the one who made guns and cannons, you are just a guard!" Hu Changyi looked very arrogant.

"Diede, you made it! As long as you can build guns and cannons, what's wrong with me being a guard for you? Hahaha..." Battalion Commander Wang laughed as he said.

"Today I'm experimenting with new weapons, I think it's very necessary for you to go and have a look!" Hu Changyi's words got the point.

"What weapon?" Battalion Commander Wang looked around and whispered.

"Grenade launcher! But it's different from the Japanese. You will know when you see it. At 2 pm, I will conduct live-fire inspections at the arsenal shooting range, you can go and check it out. Moreover, this grenade launcher may enter the front line of troops.

With the area assembly, your camp can be used as a pilot." Hu Changyi said mysteriously.

"Then I have to go and have a look!" said Battalion Commander Wang.

After running, Hu Changyi rode a horse to the machining workshop and found the person in charge Zheng Guangming: "Old Zheng, measure all the parts again, and after accurate, send them to the shooting range duty room, you can watch the parts there yourself.

Lost."

"I understand, factory director. But, can this really hit the shells?" Zheng Guangming asked, pointing to the parts of the grenade launcher.

"As long as the size is fine and the shells are fine, then there is no problem! I also have to go to the shell workshop. It would be useless to have a cannon or a shell." Hu Changyi said.

"And, our old military workers in our time and space have tried it and have all been equipped with the Eighth Route Army. What's the problem?" Hu Changyi didn't say this sentence.

After leaving the machining workshop, Hu Changyi headed west and went to the shell workshop. He saw more than 40 50mm shells. The shapes of these shells were almost the same as those of the mortar shells, but they were a little smaller. The fuse used was relatively simple.

When the collision fuse is used, there is usually a safety pin inserted into the warhead and it is pulled out before firing the cannon.

Unlike mortar shells, grenade launchers use the launching medicine in the hollow medicine tube in the fixed tail wing as the power for firing, and will not install the launching medicine bag like the mortar shell to increase the range.

Turning on the system assistance, Hu Changyi saw the data of this batch of shells: carefully manufactured grenade launcher 50mm grenade, qualified product. The maximum range is 700 meters, the effective range is 400 meters, the explosion radius: 1 meter, and the shell can only be exploded (

Experimental bomb); 8 meters (actual combat bomb).

The simple and easy-to-understand introduction made Hu Changyi very happy. As long as this experiment is over and this simple structure of small mortar cannon is mass-produced, the Eighth Route Army's shortcomings in melee heavy firepower will be compensated.

"Come on, load the shells and go to the shooting range!" Hu Changyi greeted and took the shells to the shooting range.

At this time, Zheng Guangming was already waiting here, and Hu Changyi was not polite. After taking over the parts brought by Lao Zheng, he quickly loaded a tripod dragon grenade launcher.

System assist: Dinglong grenade launcher, well-made... Looking at the judgment given by the system assist, Hu Changyi finally smiled.

At two o'clock in the afternoon, cadres from all over the arsenal had already arrived, including Minister Zhang, Company Commander Guo, and Battalion Commander Wang.

Of course, there are also technical representatives such as Yuan Shouge Luda Zheng Guangming and Fu Yunpeng. Although everyone is weird about the little guy who does not look like a grenade launcher and a mortar is not like a mortar, he thought that this was designed by Hu Changyi and

It was made, but full of expectations.

"Produced by Changyi must be a fine product!" This concept seems to have quietly become popular.

"Minister Zhang, do you want to say a few words?" Hu Changyi asked Minister Zhang on the shooting range.

"Okay, okay, you guys are busy with yours! I, Lao Zhang, am a spectator today, and I won't join in the fun!" Minister Zhang laughed and asked the experiment to continue.

"Now, everyone, except the tester, entered the safety wall immediately." Hu Changyi shouted with the iron horn.

"Hurry up, the tester prepares the experimental bomb!"

Under Hu Changyi's command, the unrelated personnel were evacuated, and the tester continued to stay where he was and began to check the equipment at the end.

"Performers, please pay attention, one shot, launch preparation, 200 meters of target position!" Hu Changyi continued to shout.

After Hu Changyi finished calling, the testers put an experimental bomb into the barrel and pulled down the iron to prepare for launch.

Unlike the Japanese grenade launcher, the tester will adjust the angle of the barrel and place the plumb gauge on a 100 ruler. This is like a mortar. It uses the angle of the barrel to control the parabola of the warhead to determine the bounce point.

It also turns hair pulling into hair pressing, making it easier to operate.
