Yamaiwa Shouichi led more than 200 Japanese troops towards the mountainside, during this time, the flash continued, Yamayan Shouichi almost fantasized about the situation of capturing the sharpshooter alive, and then Kamimine was extremely optimistic about his idea of his sharpshooter troops, and he was ordered to form such a unit, and even His Majesty the Emperor personally awarded him a medal!

Yamaiwa Moriichi slowly approached the flash, and he ordered several soldiers to outflank him, and at this time he sensed that something was wrong, because the sharpshooter didn't seem to realize that he was surrounded, and the flash continued.

At this moment, several Japanese soldiers had approached the flash point, a soldier shouted, stabbed the flash point with a bayonet, only to hear the sound of "dang", the bayonet actually stabbed on the stone, before they could react, only saw a dazzling flash, and then a deafening explosion, countless shrapnel knocked these soldiers into a sieve!

It turned out that this trap was set by Chen Fei, he used an electronic watch that could flash to attract the Japanese army, and placed a grenade under the electronic watch, this grenade was opened by Chen Fei, tied the pull ring with a thin wire, and then tied the thin wire tightly to a protruding stone, so that when the Japanese soldier touched the thin line, he pulled the grenade!

When the mountain was guarded like thunder, Chen Fei had already left the battlefield far away and advanced towards the rear of the Japanese army.

The Japanese later called Chen Fei's attack a "strange battle" because no enemy was found from beginning to end, and a total of 26 officers and soldiers were killed, all of whom were killed by one shot, including those who died at the observation post.

The reason why the Japanese army believed that the battle between the observation post and the stronghold of Xiaowang Village was caused by the same person, because they analyzed the warheads in the corpses in detail and the bullets in both places were of 5.8 mm caliber, which surprised the Japanese army.

What is even more incomprehensible to Japanese experts is that small-caliber bullets can hit so far! The small caliber of the bullet means that the bullet case is small, and the small bullet case means that the bullet can be loaded with less propellant, and if the propellant is less, the bullet will naturally not be able to hit far.

The equipment in the Japanese observation post was destroyed by Chen Fei, and before they had time to replace it, Lin Yuan's large army came to the door, and on March 23, Lin Yuan led the Dingwu army along the west side of Xiaowang Village to Zhangyi Station in the distance.

From the garrison of the Dingwu Army on the east bank of the Liao River to Shenyang, there was an endless plain, so Lin Yuan was not worried that the Japanese army would use the terrain to ambush him, but despite this, Lin Yuan still sent a team of more than fifty scouts to reconnoiter in advance at a position of one thousand meters in front of the large army.

At ten o'clock in the morning, the dark clouds were thick, and Lin Yuan was in the middle of the team, when someone came to report: The front is only seven kilometers away from Xiaowang Village, do you want to camp?

Lin Yuan asked, "How many Japanese troops are there in Xiaowang Village?" ”

The man replied, "There are less than four hundred." ”

Lin Yuan said: "The Japanese army has such a small number of troops, they must not dare to confront us head-on, we are stationed in Xiaowang Village tonight." ”

At this moment, suddenly, a black dot appeared in the sky in the distance, and in the blink of an eye, the black dot became larger and larger, followed by a terrible whistling sound, and the thing soon fell on the west side of the procession, eight hundred meters away.

A violent explosion came, and that thing turned out to be a cannonball!

This made Lin Yuan very surprised, you have to know that the nearest artillery of the Japanese army is fifteen kilometers away from here, how did their artillery take down here?

When he was confused, another shell hit, this shell fell less than four hundred meters to the east of the team, which made Lin Yuan even more confused, the second shell was more accurate than the first shell, indicating that someone was calibrating the enemy's shooting, but his team dragged on for a long time, even if someone corrected the shooting, his own forward troops could also find it!

Both shells were so powerful that they blew up a large circle crater on the ground that was more than eight meters deep and had a radius of five meters!

Not only Lin Yuan was confused, but the people below were even more confused, Liu Dart hurriedly found Lin Yuan and asked, "Lin Shuai, where did this cannonball come from?" How can you hit so far? ”

Lin Yuan thought to himself: "Can hit a heavy artillery for more than ten kilometers, does the Japanese army have such weapons?" Could it be that this is the so-called secret weapon of the Japanese army? ”

Lin Yuan first thought of the coastal defense artillery in Lushun, it is very likely that the Japanese dismantled the coastal defense artillery there, transported it here, and then fired at themselves, but can the shells fired by the coastal defense artillery in Lushun be so powerful?

Could it be that the Japanese developed a new artillery with a range of more than ten kilometers? This possibility is not impossible, there are many factors that affect the range of artillery, such as the length of the body tube, generally speaking, the longer the body tube, the longer the propellant gas acts on the projectile body, the higher the initial velocity of the shell, and the longer the firing range is naturally far; For example, the type and shape of the propellant, the propellant of this era, which was nitroglycerin-based smokeless gunpowder, could they send such a powerful shell to such a long distance?

Lin Yuan thought of some other ways to increase the range of artillery shells, such as rockets, the significant difference between rockets and artillery shells is that rockets come with rocket engines, so the range is far larger than artillery shells, Lin Yuan quickly denied his idea, rocket engines have high requirements for fuel, and in this era, oil has not been applied on a large scale, can the Japanese have this technical ability?

Lin Yuan thought about it, and suddenly thought of a problem, that is, such a powerful artillery, its body tube must be made very thick, and the use of multi-layer body tube techniques, so as to withstand the huge bore pressure of gunpowder gas, you must know that the gas pressure that can push the shell more than ten kilometers away is definitely not something that ordinary artillery barrels can withstand.

The problem is not only the body tube, the artillery that can push the shell to more than ten kilometers away, its recoil is absolutely amazing, which requires a lot of weight of the hoe to support, the tube, the result of the large increase in the volume and weight of the hoe is that the weight of the gun has also increased significantly, you must know that in this era, although the car has developed greatly, but there is still a great distance from the large-scale application in the military, if you use horses, how many horses are needed to pull such artillery!

Even if the Japanese found enough horses, bigger problems followed, in this era in Northeast China, most places were still dirt roads, even if the post roads built by the government were not asphalt concrete structures, such roads could not bear the weight of artillery, such artillery would sink into the ground when it reached it, and such artillery would have no tactical value.

Suddenly, Lin Yuan had a flash of inspiration and seemed to have figured out the Japanese method.
