Commander Oyama Yan's analysis is not bad at all, if a plundering artillery chariot falls from a height of four meters, not only will the people inside be shocked to death, but the predatory artillery chariot will also be thrown into combat effectiveness, and the huge impact force may damage the tracks and deform the connecting parts between the barrel and the body.

Although Commander Oyama Iwa believed that the plundering artillery chariots would not dare to drive directly down from the edge of the trench, he still ordered the Japanese soldiers to prepare explosive packs, and if the plundered artillery chariots used any special means to drive down from the edge of the trench and were unharmed, he threw out the explosives packs and blew up the plundering artillery chariots.

The Japanese soldiers in the fortress in the trench were ready for battle, and all the explosives were ready, but what they didn't expect was that the artillery and chariot of the invasion stopped two or three hundred meters in front of the trench.

The stopped plundering artillery chariots immediately poured fire on the infantry of the second line of defense, and the Japanese soldiers in the second line of defense did not flee, but hid behind the breastwork, intending to make the breastwork resist the attack of the plundering artillery war.

However, the Japanese soldiers obviously overestimated the defensive power of their breastwork, and as soon as the shells of the plundering artillery chariots hit the breastwork, the breastwork immediately scattered and exploded, and all the Japanese soldiers behind them were reduced to minced meat.

Not only artillery shells, but also machine gun shells could easily penetrate the breastwork, killing all the Japanese soldiers behind.

Seeing this scene, Commander Oyama immediately ordered all the Japanese soldiers in the second line of defense to enter the first line of defense, that is, the trench with a width of 40 meters and a depth of 4 meters.

Commander Dashanyan thought about it this way, he thought that the reason why the artillery chariots did not rush into the trench was to cover the infantry of the Huaxia Army, and after a while, thousands of infantry of the Huaxia Army would rush over and use the ladder to go down into the trench, so Commander Dashanyan ordered the Japanese soldiers to enter the trench for defense.

The Japanese trench is not only such a fierce place as a fortress, inside the wall opposite the fortress, there are also a number of long corridors, and there are firing ports in the long corridor, and the Japanese soldiers shoot outside in the long corridor, and they can work with the fortress to launch a front and rear flanking attack on the enemy infantry who enter the trench, and the enemy infantry will be attacked on their backs when they enter the trench, and how many people will die.

When the Japanese army was building the defense line of the Lushun fortress, they specially set up an infantry passage between the three defense lines, and after receiving the order, the Japanese soldiers in the second line of defense immediately passed through the infantry passage and entered the first line of defense, and drilled into the corridor inside the wall to prepare to shoot.

When the Japanese soldiers were ready, they saw fifteen LCC-5-1 trucks rushing from the Huaxia Army's position, each of which looked heavy and seemed to be filled with infantry.

The LCC-5-1 truck stopped at the edge of the trench, and what came down from it was not the Chinese infantry with loaded guns, but a few guys with long pipes, who put the long pipes on the top of the trench and ran away, and then only heard the sound of "stomping" coming from the car, only to see the black liquid shooting out of the long pipe like an arrow, pouring into the trench, the black liquid also exuded a strange smell, it was oil.

It turned out that the sound of "stomping" was emitted by a water pump in the car, which provided power to shoot oil from the round pipe into the trench.

The Japanese soldiers in the trench were a little puzzled at first, why the Huaxia army poured oil into the trench, but they soon understood that the Huaxia army poured oil to carry out a fire attack.

The Japanese soldiers were so frightened that they ran out of the fortress and the corridor screaming, and ran for their lives to the place where there was no oil in the distance, but the Chinese army did not give them a chance to escape, and one after another incendiary bombs were fired from the plundering artillery chariots, directly igniting the oil in the trench.

The fire was wrapped in thick black smoke and rose into the sky, and the hot flames scorched the faces of the soldiers of the Huaxia Army, and even the armor of the artillery chariots of the invasion was hot.

The people outside the trench are still like this, and you can imagine how miserable the Japanese soldiers in the trench are, the flames are burning on their bodies, and the pain is incomparable, and every Japanese soldier hates his father and mother for giving birth to him!

The terrible shouts came out of the trenches, those shouts, simply not people can come out, the sound is so loud that it almost overshadows the whirring wind, the sound is so miserable that the soldiers of the Chinese army can't bear to hear it, and some soldiers even want to go down to rescue the Japanese soldiers...... Chinese people, after all, are still the majority of kind.

The fire in the trench spread for seven or eight hundred meters, and the oil poured down could burn for an hour, and when the oil was burning, the Huaxia army could not cross the trench, so the Huaxia army's attack stopped for a while.

The infantry did not attack for the time being, but the artillery chariots of the plundering were not idle, and they were divided into two groups, one to the left and the other to the right, to attack the other heavy artillery on the third line of defense.

The plundering artillery chariots are only a few tens of meters away from the trenches, and at this distance, the heavy artillery cannot hit them, because the firing angle is not so small, while the plundering artillery chariots are just right to hit the heavy artillery.

With the light of the fire in the trenches, the plundering artillery chariots slaughtered the heavy artillery on the third line of defense, and one by one the heavy artillery was destroyed, and soon, there was no longer heavy artillery protection for thousands of meters of the defense line.

The Lushun fortress has no heavy artillery, like a tiger without sharp teeth and claws, without fear.

An hour later, the fire in the trench was extinguished, and only charred corpses remained at the bottom of the trench, many of which showed no signs of flames, all of whom had died of suffocation because the fire had consumed a lot of oxygen.

Without exception, all the forts in the trenches exploded, because the fire scorched the fort, causing all kinds of bullets and explosives to explode inside.

Commander Dashanyan and the Japanese soldiers originally thought that after the fire was extinguished, the infantry of the Huaxia Army would attack, and they planned to inflict a large number of casualties on the infantry of the Huaxia Army when they attacked, but Commander Dashanyan's wishful thinking once again failed, and the infantry of the Huaxia Army did not attack at all, and it was the artillery that came to attack.

Sixty HP-2 75-mm howitzers and thirty HP-3 105-mm howitzers lined up in front of the Lushun fortress defense line, and many of the heavy artillery on the third line of defense were blown up, so the artillery of the Huaxia Army had nothing to fear.

In the original plan of the Huaxia Army, after burning the Japanese soldiers in the trenches with fire, the infantry of the Huaxia Army immediately dispatched to attack the Lushun Fortress, but later Li clearly thought that if the infantry of our army entered the Lushun Fortress, the Japanese army would definitely do its best to counterattack, and the infantry of the Huaxia Army would definitely suffer heavy casualties at that time, so Li Ming changed the battle plan and did not let the infantry charge, but let the artillery attack.

Ninety artillery pieces spat out tongues of fire at the defense line of the Lushun fortress, some shells fell in the Lushun fortress, and some shells exploded on the wall of the third layer of defense line, the third layer of defense line was fifteen meters above the ground, made of concrete, like a city wall, but in front of the shells, this city wall was vulnerable.

In front of the 90 artillery pieces, the third line of defense quickly collapsed into more than a dozen large gaps, and at this time, the Huaxia army still did not rush into the gaps, they still stayed outside the trenches, "obscenely" firing shells, and wanted to kill all the Japanese soldiers inside.

The accuracy of the attack of the ninety guns was much higher than that of the Monkey King's airship, and almost all the shells fell where there were Japanese soldiers, and the barracks, ammunition depot (above-ground part), and grain warehouse (above-ground part) were all hit by shells, igniting a large fire.

Under this style of play of the Huaxia Army, Commander Dashanyan had a feeling that the general trend had gone, and he was determined to repay the emperor with death, so he solemnly ordered to hold the fortress of Lushun at all costs and never retreat.

The fighting will of the Japanese soldiers is rare in the world, everyone is guarding the Lushun fortress, no one wants to retreat, in fact, Li understands the truth of "three is missing one", when surrounding the Lushun fortress, there are many areas that can be withdrawn, so the Japanese soldiers do not retreat.

The shelling lasted for more than two hours, and 90 artillery pieces fired more than 3,000 shells into the Lushun fortress, more than 3,000 shells, and it took 20 days to transport 5,000 shells for Li Mingming, and more than 60 percent of the shells were used up in today's overnight battle.

Li understood that the bombing was almost done, so he ordered the artillery to stop the shelling, and ordered the invading artillery chariots and infantry to act together to storm the fortress of Arthur and completely destroy the Japanese army.

In order to allow the artillery chariot to cross the trench, the Huaxia army used a bridge-erecting vehicle, and the length of a single bridge plate of the bridge-erecting vehicle was ten meters, which was far from forty meters, but the Huaxia army was clever and witty, and did not build a bridge on the trench, but built an inclined plane on the side of the trench, and the invading artillery chariot went down from the inclined plane, and then rushed up from the inclined plane, and really rushed through the trench in one fell swoop.

The artillery chariots of the plunder rushed through the trench and immediately rushed to the interior of the Arthur Fortress, the scale of the Arthur Fortress almost caught up with the small city, and there were all kinds of shops in it, which were all opened by the Japanese, as soon as the war broke out, the Japanese merchants fled one after another, and only the Japanese army remained in the entire Arthur Fortress, and those houses became a good cover for street fighting.

At this time, more than half of the houses had been razed to the ground by artillery shells and turned into pieces of ruins, which were good places for Japanese soldiers to hide, especially Japanese soldiers often committed suicide attacks, so the Huaxia army must be extremely careful.

Fortunately, the Huaxia army had the plundering artillery chariots as support, and during the battle, as soon as the threat of the Japanese soldiers was discovered, the Huaxia infantry immediately hid behind the invading artillery chariots, and waited until the enemy situation was clear before continuing the attack.
