At the same time, the waist valley position.

The militia soldiers were frantically digging into the bunkers, and they knew the importance of this blocking mission, and they did not dare to slack off.

"Makqin, Makqin set me up here, give me cement and steel bars to cast permanent fortifications, once the little devil comes, this is the line of life and death, there is Makqin, the little devil wants to come, you have to fill in the ...... for Lao Tzu."

"Set up a machine gun array here, form crossfire, don't leave Lao Tzu a dead end for shooting!"

Mao Ying was in charge of the arrangement of firepower in front of the battle, constantly yelling, in fact, he was just making some fine-tuning, those soldiers were all experienced in a hundred battles, and most of the time he didn't need to do anything at all, they had already consciously prepared for it.

"I said Battalion Commander Mao, don't you pretend that you're busy? Come back and help us get some more explosives packs when you're free! The big bear shouted angrily.

"This is the first time I have led the team independently in the real sense, and I am the main force in the face of Abe Norihide, how dare I be careless?"

Mao Ying said quite stupidly, when he came back with Lu Yuan, he once thought that no matter how strong Lu Yuan was, he was only one person, and the quality of ordinary officers in the regiment would definitely not be able to keep up, and he was also a graduate of a regular military academy, so it was difficult to think of the limelight, and he could go down in history with the Sichuan Army Independent Regiment.

But who knew that when he arrived, he found out that although no one here had gone to a military academy, he had a hand in the battle, just like the firepower arrangement of this position, he almost didn't have to interfere himself, so that when he was saving worry and effort, he had a feeling that the hero was useless.

Sometimes, he couldn't help but hope that these soldiers and officers would be stupid, so that he could show his hands and show off.

The big bear sneered, as if he had seen through Mao Ying's thoughts, and said: "Things have come to this point, we can only fight, and the result is not in our hands at all, do you think that if you roar loud enough, it will be useful?" ”

“…… I'm afraid that the head of the regiment will be disappointed in me! Mao Ying said.

"Don't worry, as long as we do our best, the deserters will know!"

The big bear said, "Did the scout let it out?" Don't forget this, you can release as much as you can, such a heavy rain, don't let the little devil come to you, we don't know! ”

"I'm not stupid......"

Mao Ying said, finally came over to help tie the explosive bag, and looked at a group of soldiers in the col who buried gasoline barrels in the ground and said, "You say, what kind of flying thunder cannon is this, is it really useful?" ”

"It's the first time I've used it, so how do I know? But when the little devil comes, you'll know! ”

The big bear laughed strangely, looked at the soldiers who buried the gasoline barrels, and immediately roared: "You stupid people, don't bury them so densely, the little devils will come over later, and they will all be blown up. ”

“…… Yes, yes, it's the deputy battalion commander, we will correct it immediately! ”

The warriors craned their necks and screamed, and the big bears rolled their eyes.

"Hey, listening to the captain's explanation, it seems to be useful, but after all, I don't feel at ease......" Mao Ying said.

The big dog bear said in a sullen voice: "If you want to rest assured, you go and pull the foreign artillery of your 88th Division over, since there is no one, then don't talk nonsense, who doesn't want to use good things, but no......"

Mao Ying didn't speak, and helped tie the explosive bag together, while thinking about how Lu Yuan came up with this method, isn't he afraid of exploding?

Flying thunder cannons, in fact, cannot be considered cannons, and the principle of grenadiers is almost the same.

First of all, strengthen the iron barrel fire door, and put a primer fire at the bottom, which is generally a low-explosive and high-pressure explosive such as black powder.

The primer is then covered with a layer of insulating insulating from combustion, and an explosive pack is placed on top of the filler.

The purpose of this was to avoid igniting the primer below, and then ignite the explosive pack above.

The principle of action is to use the gas when the primer is ignited to expand violently, and then push the filling to push out the explosive package on it, and then the explosive package explodes in the enemy group, thereby causing damage.

The biggest role of the gasoline barrel is not to launch, but mainly to orient and increase the range.

Therefore, when the flying thunder cannon is fired, it is a lot of attention.

First of all, the fuse on the explosive package and the ignition time of the primer should be very appropriate, if the primer ignites late, the explosive package explodes directly in the gasoline barrel, not to mention how ugly the consequences are.

If it's too early and the explosives pack falls into the enemy group before it explodes, the enemy will have plenty of time to deal with it, and then it will only be a waste of explosives.

Fortunately, Lu Yuan was extremely interested in this flying thunder cannon at the beginning, so he checked a lot of information, and remembered the length of the fuse, the number and proportion of the primer fire very clearly, and after the fighter plane, there were a lot of abandoned empty oil drums in the county, which gave him the confidence to use it directly on the battlefield without experiments.

Of course, none of the data he saw from the data was absolute, and the gasoline barrels were too thin, and the uneven weight of the explosives packets and the slight tilt of the filling could make the final result unpredictable.

In those historical documents, it is common for explosives to explode during launch, and explosive packets to fly to the positions of one's own team or fraternal troops, causing many casualties.

Therefore, in addition to the name of the flying thunder cannon coaxed by the ox, this cannon also has a name called the conscienceless cannon, which is the case of accidental injury.

Fortunately, this time the position of the Folding Waist Valley is long and narrow, and it occupies high ground, and the arc of firing the explosive package is not too high, which is relatively easy to control, which is why Lu Yuan dared to pull this cannon up for experiments.

Of course, in addition to these shortcomings, the lethality and range of the flying thunder cannon are still considerable.

First of all, the range can reach two or three hundred meters, and the explosive power of the explosive package cannot be underestimated.

What's more, their artillery fire has been mainly using grenades fired from small grenades for a while, and it is conceivable that such a fire of explosives can be caused by such a cluster bombardment to the other side!

"I hope that the head of the regiment's invention this time can really play an effect like a threshing machine!"

Mao Ying thought about it while looking at the twenty or thirty gradually buried gasoline barrels and said, although he didn't have any hope for this thing in his mouth, but in his heart, he was extremely hopeful that this flying thunder cannon could exert the power that Lu Yuan said.

Otherwise, he would have to let these brothers fill with their lives, and in that case, he did not know how many of the 1,400 or 500 men would be left after this battle.
