At first glance, this fuse looks similar to a regular domestic shell fuse. The head of the fuse has a protruding aluminum firing pin cap, a transport safety pin with a pull ring in the middle, and a detonator at the bottom.

But as Qi Baoshan, who has worked in Taiyuan Arsenal and Chongqing Arsenal, knows very well that this fuze of the devil is different from ordinary domestically made fuzes, and has a very advanced inertial insurance.

This kind of safety in the shell after the launch, the upper centrifugal hoop due to the inertial recoil, flattened the ingots spring down, so that the centrifugal is in a free state, when the shell in the barrel accelerates, because the firing pin backseat suppresses the centrifuge, restricts the free movement of the centrifuge, so that the firing pin can not easily fire the rear detonator.

After the gun ejects the muzzle, the velocity decreases, the recoil of the firing pin disappears and is lifted by the safety spring, and the centrifugal son can then release the binding effect on the firing pin due to the centrifugal force, complete the firing preparation, and explode at the first touch.

As a result, this device constitutes an intra-chamber and muzzle safe, which increases the degree of safety when firing and greatly reduces the risk of the shell exploding.

When the shell hits the target, the firing pin strikes the fire cap, causing the detonator to detonate the charge inside the shell.

……

Soon, after figuring out the specific structure of this fuse, Qi Baoshan began the most critical step, "Deal with the firing pin." ”

Qi Baoshan knew that the main reason why small-caliber grenades could not effectively kill armored targets such as tanks was that the instantaneous fuse caused the shell to explode prematurely on the outside of the armor, making it difficult for the shell fragments to penetrate the steel armor plate of the tank.

Therefore, he planned to imitate the characteristics of anti-aircraft artillery shells, use 70-millimeter grenades with fuses to take a close-range flat fire method, and use the kinetic energy of the shells themselves to smash through the weak armor of the devil bean combat vehicle!

Thinking about the result he wanted, Qi Baoshan decisively aimed the vise in his hand at the firing pin ...... of the fuse.

His goal was simple, to deactivate some of the firing pin's functions and turn the shell into an armor-piercing grenade that could delay detonation.

However, Qi Baoshan also knew that this modification could be described as extremely primitive, and it was likely to make the shells completely become duds. However, in his opinion, it doesn't matter even if it turns into a dud, but it is used to smash the armor of the devil tank.

As for the personnel inside, it is not necessary for the shells to explode in order to kill. Because the devil's Type 94 tank is a riveted armor plate, just the rivets flying around in the compartment after the armor is shattered are completely enough for the devils inside to drink a pot.

Soon, after Qi Baoshan had finished processing one fuse and reloading it, he began to modify the next shell.

……

In this way, after waiting for more than thirty minutes outside the courtyard, as the alarm of the arrival of the devil came from the guard posts on the periphery, Qi Baoshan, who was pale, also walked out of the house with a smirk with a smirk on his face.

……

Seeing Qi Baoshan come out safely, Zhao Shixun's heart finally fell to the ground gently.

In the face of Qi Baoshan's disregard for his safety, he couldn't bear to reprimand the other party. Walking forward with a straight face and taking the cannonball in the other party's hand, Zhao Shixun carefully held it in front of him and looked at it for a few seconds.

"For this thing, you kid really don't even want his life......

Hearing this, he smiled stupidly, Qi Baoshan wiped the cold sweat on his face, and then instructed a few of his subordinates to enter the house and take out all the transformed shells.

"A total of four grenade ...... changed, hehe...... As long as you can put the firing distance within the direct firing distance, I guarantee that the little devil's bean chariot will never return! ”

Looking at Qi Baoshan, who was full of confidence, Yang Chenghu on the side couldn't help but step forward and look at the cannonball in Zhao Shixun's hand.

"Can this thing really be like a war defense gun, and puncture the little devil's tin can at once?"

"Don't worry, Battalion Commander Yang, the devil's Type 94 tank only has a mere six millimeters of armor, not to mention this thing, even the steel core bullet of the Makqin heavy machine gun can be cleaned up within 100 meters!

The main reason why you failed to fight tanks before was that the grenades made in our border area were not filled with regular explosives, but ordinary black powder. It takes a lot of effort for that thing to explode and injure individuals, let alone blow up the devil's tank. ”

Speaking of this, Qi Baoshan didn't hold it up, but looked at Zhao Shixun and Yang Chenghu and said seriously:

"But although I modified the fuse, this devil's ninety-two rifle has a short barrel and low muzzle velocity after all.

Therefore, in order to ensure the success rate of the opportunity tank, we must put the firing distance within 100 meters!

Therefore, the two commanders must be mentally prepared. ”

Hearing that the distance was to be put to 100 meters, Yang Chenghu didn't care.

In his opinion, he doesn't care about zero-distance physical bombing tanks, and he is afraid of battles at a distance of 100 meters.

"Brother Qi, although you can rest assured, I, Yang Chenghu, have no other skills, but I am still sure of protecting a cannon.

You just have to rest assured that you can shoot the tanks, and as for the task of attracting tanks and covering them, our special battalion will take care of them all for you. ”

Seeing Yang Chenghu on the side, Zhao Shixun didn't say anything. After all, although the casualties of the special service battalion are not small, the main force is still there, so it is no problem to protect a gun.

Thinking of this, Zhao Shixun quickly took out the defense map drawn by He Zhendong and handed it to Qi Baoshan.

"Brother Qi, this is the defense map of our Nanyang Village, you choose a suitable ambush location according to your ideas."

Regarding the focus of the defensive battle in Nanyang Village, Zhao Shixun initially envisioned to lure the enemy into depth, and then look for an opportunity to defeat the devil's tank.

And now that there are shells that can hit tanks, things are much simpler. As long as Qi Baoshan chooses the artillery position, he and Yang Chenghu will be able to deploy defenses around him, and there is no need to think about luring the enemy into the depths.

Hearing this, he took the map, and after a few brief glances, Qi Baoshan quickly chose a position with a wide firing range and cross-fire cover on it.

"Just this courtyard, when the time comes, I will ask the soldiers to make a few gaps in the courtyard wall around it, so that no matter if the devil's tank comes in from that road, I can give them a hard time!"

Hearing this, Yang Chenghu and Zhao Shixun looked at the location on the map, indicating that they had no objections.

The location chosen by Qi Baoshan was located in the center of the village, and there was no less than one courtyard occupied by his own soldiers on all sides, so no matter which direction he was engaged with, the 92 infantry cannon could quickly adjust to the desired position.

"Captain Zhao, I think that's it, my people are responsible for the defense of the eight outer courtyards, and your people are responsible for the defense of the inner two courtyards while taking into account mobile support, how about it?"

"Okay, no problem."

Seeing Zhao Shixun's readily agreed, the worry on Yang Chenghu's face instantly disappeared. After hesitating for a while, he finally decided to ask someone to go to Xu Dongsheng and ask him to hand over all the six Type 89 grenades he had seized from the Tuwo Village stronghold to the independent detachment.

At the moment of life and death, Yang Chenghu can't care about what you and me, anyway, his gunners lack training, and it won't play much role if he stays. In that case, it might as well give it all to Zhao Shixun's grenadier squad.

At the same time, Zhao Shixun also personally took Yang Chenghu to a courtyard and explained his idea of using the cellar to avoid the shelling of devils to the other party.

Zhao Shixun told Yang Chenghu that when the war started, he must first let the large army hide in the cellar and stand by, and leave a few observation posts outside.

Before the end of the devil's shelling, the living forces should try not to rush out to meet the battle, so as to reduce unnecessary casualties.

Regarding Zhao Shixun's suggestion, Yang Chenghu did not object. In the encounter not long ago, Yang Chenghu had just learned the power of the devil's long-range firepower. Although he is now occupying yards and houses to fight street battles, Yang Chenghu is still very clear about how much defense the farmhouse's adobe houses have. This thing, not only is it difficult to provide cover during shelling, but it will also turn into a large grave bun.

At the same time, Yang Chenghu actually muttered a little in his heart about street fighting, a combat method that he had rarely encountered before.

After all, this kind of face-to-face combat style was strongly avoided in the Eighth Route Army in the past. The longest fighting style he and his troops have experienced, mainly in field ambushes and mobile warfare, is therefore not good at this kind of street-by-street street fighting.

Seeing that Yang Chenghu listened extremely carefully from beginning to end, Zhao Shixun knew that the other party was obviously not good at street fighting. And the reason why the other party has to take the initiative to take charge of the defense of the outside line is just because Yang Chenghu's temper is like a stone in the toilet, smelly and hard, and he refuses to show weakness to others easily.

Therefore, before parting, Zhao Shixun did not forget to tell Yang Chenghu to tell his subordinates to pay more attention to the control of street corners and walls, and at the same time try to use grenades to solve the enemy outside the line of sight.

As the saying goes, the words are as light as water three times, Zhao Shixun knows that he has done his best, if the other party doesn't listen, then it is meaningless to talk nonsense about himself.

……

After the two separated, Zhao Shixun led people to open up the two adjacent courtyards under his control according to Qi Baoshan's requirements, and then opened several openings in the four walls that could accommodate the entry and exit of the ninety-two rifle guns.

The position He Zhendong chose for Zhou Yu was very simple, it was a small urban defense formation in depth.

The outer ring follows two east-west alleys, and eight adjacent courtyards are selected in four directions, while two larger courtyards are used as the inner defense ring.

In this way, no matter from which position the devil attacks, he will encounter fire from at least three directions. Moreover, once the devils successfully break into one or two courtyards, they will face fire resistance from the flanks and inside, and it will be difficult to quickly expand the results of the battle.

According to the minelaying distribution of the previous special service battalion, they concentrated on the dense minefields in the four directions of the courtyard, the north and south sides, and the southeast, northeast, southwest, and northwest corners, leaving only a small gap in the east and west alleys that entered the village.

In this way, once the war starts, it is very easy for the attacking troops of the Japanese puppet army on the east and west sides to penetrate deep into the defensive line, and it will naturally attract the main offensive force of the devils into the ambush circle.
