At this time, Lin Fei had two armored divisions, of which the first division was stationed on the first line of Shanhaiguan, preparing to attack the Japanese army, and the second division was stationed in Hanyang to deter the remnants of the Qing court.

From the distance point of view, it is more convenient to transfer the first division, but the first division is preparing to attack Mukden, which is the nest of the Japanese army in the northeast, so the first division cannot be mobilized, so the second division can only be mobilized, but the distance of the second division is relatively far, Lin Fei weighed it repeatedly, and decided to mobilize sixty invading artillery and combat vehicles of the first regiment of the second division to assist the Lushun front.

The second division and a regiment were transferred from Hanyang to Lushun, and it took ten days, during which the Monkey King airship continued to bomb the Lushun fortress, and successively blew up some barracks, warehouses and fortresses, but for the Japanese army, these were skin wounds, and the Japanese army immediately began to dig underground fortifications and hide food and weapons since they knew that there were airships in Huaxia.

The Chinese army did not launch an attack for ten days, which can make the Japanese arrogant, the Japanese governor of Korea, the commander-in-chief of the Qing garrison Nogi Noshinori openly said that the Chinese army will never conquer the Lushun fortress, and the Huaxia army will eventually encounter a complete defeat in the Lushun fortress, and finally roll out of Lushun in disgrace.

World public opinion also applauded Nogi Noshinori's remarks, especially Russia and Britain, these two countries were badly cleaned up by the Chinese army, and the British colony of Burma is still suffering from the wanton torture and killing of the Chinese army's submarines.

On January 20, 60 artillery chariots arrived at the front line of the Lushun fortress, at this time in Lushun, the temperature has been as low as minus six degrees, at this temperature, the artillery chariots of the plundering need to add antifreeze in order to maintain normal operation, this antifreeze is actually purchased from the United States, the United States began to develop antifreeze very early, in the "honeymoon period" between China and the United States, Lin Fei purchased antifreeze processing technology from the United States.

At one o'clock in the morning of January 21, the marauding artillery chariots launched an attack on the fortress of Arthur.

In order to prevent the Japanese army from laying mines, the 1st Armored Division let six "crushing minesweepers" of the invasion artillery combat vehicles in front of the road, it turned out that the Japanese army did not lay mines, to the surprise of the 1st Armored Division, the crushing minesweepers actually had a miraculous effect on the barbed wire, and the huge rollers rolled the barbed wire, which was much faster than the invasion artillery vehicles.

After approaching the defense line of the Lushun fortress, the artillery chariot of the plundering was immediately bombarded by the heavy artillery of the shore defense, and the shells fired by the 300-millimeter cannon could blow up a large crater in the ground two or three meters deep, and no one knew what would happen to the artillery chariot of the plunder.

A shell exploded next to an invading artillery chariot, and the track was violently blown off, falling to the ground with a "bang", and the crew inside was also shocked and bleeding, killing them instantly.

A shell accidentally hit a plundering artillery chariot, and the armor thickness of the predatory artillery chariot was not large, because when it was originally designed, the main threat of the predatory artillery chariot was not artillery shells, but enemy rifles and machine guns, so there was no need to design the thickness too large.

If the thickness is designed to be too large, the weight will increase sharply, after all, the material of the armor is steel, the density of steel is very large, and an increase in thickness of one millimeter will increase a lot of weight, and if the weight is too large, the engine will not be able to carry it.

The explosion of this shell directly destroyed the plundering artillery chariot, the turret was blown away, the barrel was broken, the internal oil was ignited, and the entire predatory artillery chariot was on fire.

The closer the plundering artillery chariots got to the defense line of the Arthur fortress, the more shells hit, and when they approached a thousand meters, a concrete wall more than half a meter high suddenly appeared on the ground.

The height of these concrete walls has exceeded the usable vertical climbing height of the plundering artillery chariots, and if the predatory artillery chariots want to cross these concrete walls, they must stop and blow them up, but under the enemy's artillery fire, how can they stop, and if they stop, they will not be used as targets by the Japanese army?

In fact, the 13th Division had already reconnoitred these concrete walls before the war, but when communicating with the armored division, they ignored them, which led to the armored division being unprepared for the concrete wall.

The plundering artillery chariots had no choice but to retreat at full speed and abandon the attack, and in this way, after losing five predatory artillery chariots, the armored division also stopped the attack.

The two attacks on the Lushun fortress ended in failure, and the morale of the Huaxia army was extremely low, but the Japanese lost no time in provoking again, threatening to turn the Lushun fortress into Lin Fei's Waterloo.

The 2nd Armored Division severely rebuked the 13th and 14th Divisions, believing that the failure of the 2nd Armored Division was entirely the responsibility of the 13th and 14th Divisions.

In the midst of pessimism, Lin Gecheng, the commander of the Monkey King Airship Force, proposed a solution, that is, to use the Monkey King Airship to dump oil on the Lushun Fortress, and then use incendiary bombs to ignite the oil and burn the Lushun Fortress.

The oil dumped on the battlefield would also flow into the trenches of the Arthur fortress, where it would burn and deal a devastating blow to the fortress at the bottom of the Japanese trenches.

Lin Gecheng's method was unanimously affirmed by Li Ming's people, and Lin Gecheng immediately reported to Lin Fei to mobilize a large amount of oil, sixteen Monkey King airships, each of which can carry three tons of oil, a total of forty-eight tons of oil, excluding the weight of carrying incendiary bombs, there are still forty tons of oil left, Lin Gecheng calculated, so much oil should be enough to destroy the position of Lushun Fortress.

On January 24, sixteen Monkey King airships took off from the base and came to the sky above the Lushun Fortress.

The Monkey King airship is to put oil in large oil barrels and throw it, each oil barrel can hold about 100 kilograms of oil, if it is dumped directly from the air, the oil will fly around under the action of the wind, and it will not be able to form a sufficient concentration for combustion.

Large oil drums fell from the sky, and every time they fell to the ground, the oil inside would sputter out in all directions, and it was very striking from the sky, like a black flower in full bloom.

The crew of the Monkey King airship were all sighing at this beautiful scenery, but Lin Gecheng's heart trembled, because the area of oil sputtering was too large, if the area of oil spread on the ground was too large, it would be difficult to burn, even if it burned, it was an isolated fire, and the Japanese troops in the Lushun fortress could dig and fill it, and the fire could be extinguished soon.

Although it was winter at this time, the soil was frozen and it was difficult to dig it, but the Japanese army had already prepared to deal with the Chinese military attack, and they prepared a lot of mounds in the Lushun fortress, and regularly turned the mounds to make them loose, and it was very convenient to take the soil.

Lin Gecheng took a deep breath, he didn't want to think so much, after throwing the oil, hurry up and throw the incendiary bomb, the Monkey King airship then threw the incendiary bomb, and the bright flames exploded in the Lushun fortress, but the disappointing thing was that the fireball of the incendiary bomb was over, and the Lushun fortress did not ignite a fire at all.

It turned out that as soon as the oil barrel fell, it was shattered, and the area of oil splashed inside was particularly large, resulting in the extremely scattered distribution of oil, and the Japanese army did not understand oil, and when they saw the oil falling, they knew that the Huaxia Army might attack with fire, so they immediately landfilled the oil.

Oil is lighter than water, it can float on water and burn, not afraid of water, but it is afraid of soil, and once it is buried by soil, it can no longer be burned.

Lin Gecheng was still unwilling and decided to throw oil and incendiary bombs again, but the second throw still had no effect.

The Huaxia army fell into helplessness again, and Li Ming was resourceful, and he suddenly thought of a sentence called "The fortress is the easiest to attack from the inside", so Li Ming planned to send people to infiltrate the fortress of Arthur.

However, after a detailed investigation, Li Ming found that this trick was impossible, because the entire Lushun Fortress was closed at this time, and there was no contact with the outside world at all, and the people inside could not come out, and the people outside could not enter.

In this way, it seems that you can always besiege the Lushun Fortress, although there is a lot of food in it, but there is also a day when it is eaten up, and on that day, the Lushun Fortress will not be breached, but that day will definitely be a few years later.

Li understood that there was really no way but to ask Lin Fei for help, hoping that Lin Fei would personally find a way to break through the defense line of Lushun Fortress.

Lin Fei listened to Li Ming's report on the fortifications of the Lushun Fortress in detail, and found that the biggest threat to the Lushun Fortress defense line was the heavy artillery on the third layer of the defense line, and these heavy artillery were the only things that could impress the invading artillery chariots.

Lin Fei then instructed Li Ming to make every effort to solve the heavy artillery of the third line of defense, and Li Ming reluctantly said to Lin Fei that we just can't kill those heavy artillery, so we came to ask for your help.

Lin Fei's brows furrowed slightly, thinking about how to kill these heavy artillery, naval guns, artillery, Monkey King's airship, and the plundering artillery chariot were all ineffective, and in his hands, there seemed to be nothing that could kill the heavy artillery.

Lin Fei suddenly thought of the strategy of surrendering the army without a fight, that is, to encircle the Lushun fortress without fighting, and wait until the Japanese army starved to death, the Lushun fortress was naturally taken, but Lin Fei quickly denied his idea, if he did that, there is no doubt that Huaxia was bowing to the Japanese, and the offensive and defensive battle of the Lushun fortress was no longer a simple battle, but a contest of national dignity between China and Japan.
