Armor fragmentation is not like ordinary grenades, it is a direct explosion, before the explosion of armor fragmentation, the explosive has a process of "sticking" on the target, after the armor fragmentation projectile is attached to the target, the explosion area of the explosive is significantly increased, and a larger part of the energy of the explosive explosion is transferred to the target, unlike the explosion of the grenade, most of the energy is consumed in the air.

Therefore, when the armor fragmentation projectile explodes, the pressure of the shock wave generated on the target is much stronger than that of other types of shells, so part of the inner surface of the target will fall down, and the greater the rigidity and hardness of the target, the higher the degree of collapse, and the rock is precisely the ideal object for collapse, so as soon as the explosion occurs, Japanese soldiers will be killed by the falling rocks.

Some Japanese soldiers saw that there was a danger of being killed by the explosion while hiding in the mountain, so they rushed out of the cave and hid outside, but there were also shells exploding outside, Lin Yuan's troops adopted the "thin water and long stream" method of fighting, firing five shells per minute, this speed caused very little damage to the inner wall of the gun chamber, so more shells could be fired, so many shells fell in the Japanese position, and some Japanese soldiers were blown up and killed when they came out.

The Japanese army panicked for a while when they saw that they were hiding inside, nor were they going out, but Kishimoto Yunan decisively realized that it was safest to hide behind the mountain, because the trajectory of Lin Yuan's artillery shells was an arc, and the back of the mountain was precisely the dead end of the shells, and they would never be hit by the shells.

So Kishimoto immediately ordered: "All troops hide behind the mountain!" As soon as the herald was about to go out to convey the order, An Teng Youming stood up and said, "Captain, this order is absolutely impossible!" ”

A wave of displeasure rose in Kishimoto's heart, but he still suppressed his anger and asked, "What is it for?" ”

An Teng Youming said: "Our warriors are all hiding, what if Lin Yuan's troops take this opportunity to cross the river?" Our shells will have no way to stop them. ”

Yunan Kishimoto said, "Our outer positions will stop them. ”

An Teng Yuming said: "But we and the outer positions are mutually exorbitant, and we can't put the heavy responsibility of defense on the outer positions......

Kishimoto Yunan said in a loud voice: "Anteng, don't say it anymore, my artillery is the wealth of the Great Japanese Empire, and I will never allow them to be killed or injured by Lin Yuan's shells!" ”

With the cover of the mountain, the Japanese army was spared the suffering of artillery bombardment, but the shells fell on the mountain from time to time, collapsing the stones in the cave and hitting the artillery in the cave.

The shelling of Hayashi's troops did not stop until evening, and Yunan Kishimoto returned to the headquarters from behind the mountain, and as soon as he sat down, he immediately called a meeting of the officers of the troops.

Kishimoto Yunan said first: "Everyone knows about the past few days, Lin Yuan's troops first attacked our position with flying machines. After saying this, Kishimoto Yunan remembered the argument with An Teng Yuaki that day, and subconsciously turned his head to look at An Teng Yuming, and An Teng Yumei heard Kishimoto Yunan admit his opinion, and looked up proudly, this action was just seen by Kishimoto Yunan, and Kishimoto Yunan only felt as uncomfortable as eating a fly.

Kishimoto continued: "Today, Lin Yuan's troops attacked us with artillery shells again, and their artillery shells were still relatively accurate, and they also caused us some damage. As he spoke, he handed a document to the crowd and said, "Look at it, this is the loss caused by today's shelling, we have thirty guns with varying degrees of damage, although these damages are not fatal, but they leave hidden dangers in the use of our artillery. ”

Everyone looked at the documents with heavy faces, and Kishimoto Yunan said: "Now let's analyze and analyze, how did Lin Yuan's troops discover our artillery position?" ”

Everyone looked at each other and shook their heads, and then An Teng Youming said: "I think this is the result of Lin Yuan's troops' flying machine reconnaissance!" ”

Yunan Kishimoto asked, "How did their aircraft conduct reconnaissance?" ”

An Teng Youming said: "This subordinate is not clear, Lin Yuan's troops must have special means. ”

Yunan Kishimoto nodded, and then asked, "Who else has a different idea?" ”

At this time, Nobukazu Ohgi, the commander of the Engineer Wing, said: "Your Excellency, Commander, I think there is a very good chance that there are spies from Lin Yuan's troops between us!" ”

As soon as these words came out, the whole audience was full of exclamations, and Yunan Kishimoto frowned and said, "Damu-kun, don't talk nonsense, you have to have evidence." ”

Nobukazu Ohki said, "Of course I have proof! ”

Yunan Kishimoto asked, "Evidence? What evidence do you have? ”

Nobukazu Ohki said: "The shells used by Lin Yuan's troops today are proof! ”

An Teng Yuming asked, "Captain Oki, how can the cannonball be evidence?" ”

Nobukazu Oki said: "The cannonball used by Lin Yuan today caused the rocks on the inner wall of our cave to collapse, and this kind of cannonball had appeared in the previous Northeast War! The principle of its action has been figured out by our experts, that is, it generates a powerful shock wave that destroys the tissue structure of the object and detaches the outer part of the object from the object! It is most effective against targets such as rocks and concrete, and the fact that Lin Yuan's troops have used this weapon today shows that they know that the inner walls of our caves are made of rocks. ”

An Teng Youming smiled and said, "Captain Damu, what will the inner wall of the cave be made of if it is not made of mountain stones?" ”

Nobukazu Oki said with a sneer: "This kind of armor shattering bullet has one of the biggest nemesis, that is, it is afraid of multiple materials combined, because the shock wave will enter different materials will cause a great attenuation, if we throw a layer of concrete or wooden planks on the inner wall of the cave, the armor shattering bullet will not hurt us." ”

An Teng Youming asked, "Then why didn't you do that when you built it?" ”

Nobukazu Oki frowned and said, "That's time-consuming and laborious!" And we didn't expect that the shells of Lin Yuan's troops would be able to hit here at all! Lin Yuan's troops mastered our drawback, so they thought of using armor fragmentation bullets! ”

An Teng Youming said: "Isn't it a bit far-fetched? ”

Nobukazu Ohki said, "What's so far-fetched? This seems to me to be the most plausible explanation! ”

Yunan Kishimoto saw that there was a slight smell of gunpowder between the two of them, and hurriedly said: "Okay, okay, don't say it again, let's stop this matter, today's meeting will be held here first." And they parted unhappily.

The next day, Lin Yuan learned from Su Ya that the Japanese army had sent many wounded to Qingjin, and most of the wounded were lacerations, which were cut out by sharp gravel. Lin Yuan was overjoyed in his heart, and thought: "It seems that our armor shattering bullet has worked, and the Japanese army has really suffered a lot of losses."

Lin Yuan immediately found Shen Wanqing and asked, "Is the manuscript finished?" ”

Shen Wanqing said: "According to your request, the pilot has been replaced by an artillery company commander, and the artillery company commander himself is also of good quality, and we have no problem publicizing him." ”

Lin Yuan said: "Okay, let's send this manuscript out immediately." ”

Shen Wanqing agreed, and soon sent out this draft, which immediately caused an uproar in the Japanese command headquarters headed by Yunan Kishimoto.
