The situation on Wu Dingbang's side was also known to Wei Chendong, who called Wu Dingbang directly, Wu Dingbang trembled when he saw it, or this guy is good enough, and he thinks that he is not as good as Wei Chendong in some places, such as courage, judging from the tactics proposed by Wei Chendong, it is indeed very destructive.

As a result, Wu Dingbang decided to immediately adopt Wei Chendong's tactics, and one order after another was issued.

Suddenly, the northwest moved, and in the next few days, people saw a mysterious train roaring from Lanzhou to Anhui.

Wei Chendong's father-in-law, Lieutenant General Huang Keqiang, is also familiar with the current war situation, in Gansu for a few years, the palm of his hand has long been itchy, countless times under the strong recommendation, finally came out of the rear, as the deputy commander of the Central China Front Army led five divisions into Shandong to fight, but don't think that he relied on his relationship to reach such a high position, in Gansu I don't know, Wei Chendong's military regulations are so strict, not to mention the father-in-law, even if the father wants to be a general by relationship, he can't take as much as he has the ability, everything depends on himself.

This General Huang Keqiang is also a very strong person, in the past few years, with a ruthless energy, he jumped up step by step from the subordinates, and there is no one above the Yanhuang Legion in Gansu who has not suffered defeat in his hands, including Wu Dingbang, and there are only wins and losses, in the entire northwest, no one dares to guarantee that he is sixty percent sure that he can defeat it, which shows his command art.

Huang Keqiang himself is also a martial artist, even Wei Chendong admires his skills, and he has not worked hard in Gansu in recent years, so he is definitely a first-class player, when this does not mean that he is a reckless man, after learning of the current situation, he immediately entered Heze, and then quickly broke into Jining to threaten the Jinan army and involve the army of Jinan.

The North China Front immediately responded, and the Sakagaki Fifth Division, known as the ace division of the Yue Army, immediately came to intercept it, and fierce fighting broke out between the two sides in the Yanzhou area.

Huang Keqiang first involved the main force of the Fifth Division with the strength of three divisions, and then concentrated the armored plus one infantry division suddenly appeared on the left flank of the army at night, and carried out a fierce blow, so that Sakagaki was caught off guard, Huang Keqiang personally led the main force and all the reserves to stab up, and quickly assaulted with superior forces, dividing the Fifth Division, and the 21st Brigade defeated the Fifth Division in one fell swoop, and suffered defeat at Pingxingguan and the Eighth Route Army. Terauchi Shouichi was in a hurry to let the 10th Division quickly reinforce.

In this battle, Huang Keqiang annihilated more than 10,000 enemies in one fell swoop, and greatly reduced the morale of the army, but he was not carried away by the victory, knowing that Shandong was a place where he had been operating and plotting for many years, and blind in-depth would only increase casualties, so he stayed in the Jining area, so that he could attack and retreat, just like a sharp nail nailed to Shandong, making him uncomfortable.

"Haha, Lao Huang's move is good, he is there, his Xuzhou battle plan is a bit difficult to deliver, now it's our turn", in the temporary headquarters of Bagong Mountain, Wu Dingbang was in a very happy mood, during this time, he did not order the Yan and Huang Army to launch a fierce attack on the enemy of Bagong Mountain, after all, this place is easy to defend and difficult to attack, and a blind death attack will only increase casualties, but he did not let the army idle, dozens of planes kept throwing a large number of incendiary bombs at the army position every day, and many soldiers were tragically killed alive, It's not good to hide in the cave, and it's almost smoked.

The Ogizhou soldiers are worried and swollen in the headquarters in the belly of the mountain, the 13th Division has never been so coopy since its formation, but in his position, he has suffered this disaster, he is really powerless, and now he wants to break through the siege I am afraid it is also wishful thinking, only to wait for support, but Wu Dingbang will give me time?

At the beginning of March, Wu Dingbang finally made all the preparations, and he began to deal a fatal blow to the 13th Division.

In the early morning of March 2, dozens of 300 mm caliber heavy artillery were placed around Bagong Mountain, with an order, the sound of cannons shook the sky, as if the whole earth was shaking, the army immediately ran out in horror, as he himself, the first thing they thought of was whether there was an earthquake, a place in the cave began to fall stones, from time to time there were soldiers who could not avoid being stoned to death. The heavy artillery was prepared for more than forty minutes, firing thousands of shells, and the Yue army was almost stunned, but they couldn't do anything but enjoy it silently, and they began to feel helpless, but Wu Dingbang didn't want them to feel at ease.

"How's our tunnels going?" Inside the headquarters, Wu Dingbang paced the trail back and forth.

"Commander, it's basically the same, the Bagong Mountain area is quite peculiar, there are countless large and small mountains, we have dug a lot of passages at the bottom of some small hills where the army is hiding, and a sufficient amount of explosives has also been placed in it, just wait for an order, you can let Xiao Yueben take the earthen plane", Chief of Staff Elder Zhou said with a smile on his face.

"Okay, then the second plan and the third plan will be implemented at the same time, let the devil sit on the earthen plane first, and the army that is not dead will definitely run out of the cave, and the air force will immediately attack and throw incendiary bombs...... "I have something in my hand to fight and I have a lot of confidence, and Wu Dingbang issued orders one after another.

Around Bagong Mountain, soldiers of the Yanhuang Army were sneaking in camouflage uniforms, they secretly passed bags of alchemy into it, and at the bottom of the mountain where a big hole was dug, there were piles of explosives like a hill, and after they were finished, the soldiers immediately released the long lead, and when they reached a certain position, they immediately ignited it.

With a sizzling sound, the fuse burst into flames and detonated towards the powder keg in the cave. A little later, the sound of the "boom ......" caused the landslide and the ground to crack broke out, and some of the soldiers were directly shocked to death before they understood what was going on, bleeding from the seven orifices, and the death was extremely terrifying.

Driven by instinct, some of the faint and turned the army began to flee to the outside of the cave, not long after, many of the army rushed out of the hiding place with the main force, and the plane of the Yan and Huang army swept by in time, dropping a high-explosive incendiary bomb, suddenly, the fire was full of skylight, the mountains were lit, the terrible screams spread all over the four directions, from time to time there were soldiers rolling on the ground, but they accidentally rolled down the mountain and fell to their deaths, listening to the screams outside, the soldiers of Ogizhou looked sad, and immediately ordered the troops to gather in the mountains as much as possible, In case the Yan Huang Army attacks with this move again.

After the Ninth Division and the 114th Division learned of the situation of the 13th Division, they immediately accelerated their progress and exchanged fire with [***] in the Bengbu area, Wu Dingbang knew that fighting in the terrain of Bagong Mountain, it was not possible to rely on manpower alone, so he transferred the troops of the two divisions to Bengbu early with some heavy weapons to support the [***] operation, and this batch of heavy weapons, there were dozens of 300 mm caliber artillery used by Wu Dingbang at one time, After throwing a large number of incendiary bombs at the position of the Yue army in Bagong Mountain, the planes of the Yan and Huang Army immediately filled ammunition to support Bengbu, and with the addition of this group of backbones, [***] under the numerical advantage, the attack of the two divisions of the Yue Army was finally temporarily contained.

"Commander, the Ogizhou soldiers are now only left here, here, there are still these mountains, this time the devil has learned wisely, so he stayed in the belly of the mountain and couldn't hold out, and the original tactics didn't play much role anymore", the chief of staff pointed to the map and explained to Wu Dingbang.

"Hehe, it's time for a last-ditch move to test the power of our superweapon?" Wu Dingbang did not have the slightest worry, but was eager to try.

In the afternoon, the officers and men of a regiment of the Yanhuang Army were gathered somewhere in the Bagong Mountain area, what were they going to do? I'm afraid you won't believe it, tell you that they are gathered together just to shoot cannons, why doesn't it sound unusual, but if you tell you that so many of them are just trying to make a cannon, how do you feel? Do you think it's incredible, or do you think it's a waste of human resources?

Actually, no, because, this cannon needs so many people to be able to, just kidding, how can there be such a cannon? Tell you, there is, and it's right in front of you.

"One, two, three, hey......" The soldiers lined up in a row, all put down their weapons, but they were all across a thick rope on their shoulders, and at the same time they were pulling a huge cannon, and there were railroad tracks under the artillery, because only in this way could it move, otherwise, such a big guy, even if a regiment was sent to pull it, and, behind the cannon, there was a heavy tank pushing at full power, what a cannon this is, let you look at the data below to imagine.

The total length of the gun is 52.3 meters, the width is 8 meters, the height is 13 meters, the weight is 1500 tons, the caliber of the gun is 1000 mm, the barrel is 35 meters long, the gun weighs 450 tons, the armor-piercing shell weighs 8 tons, the high-explosive bomb weighs 6 tons, the propulsion fuel alone has nearly three tons, the projectile rate of fire is nearly 1,000 kilometers per second, and the firing range has reached the farthest 50 kilometers.

This kind of cannon is a typical train cannon, when the Yanhuang Army was preparing to develop its own weapons, Wei Chendong proposed to develop this kind of cannon, because he knew that Xiao Yueben would often hide in the belly of the mountain in the future, at this time, there must be a special weapon to drive them out, even in the most difficult period, he did not let the development of the train cannon project stop, and finally this first super-large train cannon was debugged a few months ago, and it was ready to be put into war, and it was named "Xiao Houyi" by Wei Chendong, which means to use it to shoot.

The soldiers of a regiment looked at this huge guy, and they were also speechless for a long time, and everyone was full of energy, looking forward to the power of this big guy.

"Xiao Hou Yi" was quickly installed by the soldiers, and experts who were familiar with "Xiao Hou Yi" were also on the side from time to time.

Of course, this kind of cannon cannons can't move with the army like other cannons, every time it is moved, it must be disassembled into parts before it can be transported, so when it arrives at another place, it must be installed first, because this kind of cannon has a huge anti-shock force after hitting the shell, so there must be something to help it unload, otherwise there will be big trouble, so it has to be placed on the rail, which is called the train gun.

When Wei Chendong thought of developing a train cannon, he proposed to solve the problem of rails, after all, there may not be suitable rails in the place where the battle is to be fought, and if it is built temporarily, it will take too much time.

After all kinds of ideas of the rear experts, they finally tried to produce a movable rail, the reason why it is movable is because it can be disassembled and taken away at any time, and the material for making it is quite expensive, it is an alloy invented by Yanhuang Junhua with great efforts, this alloy is very flexible, and the strength is very high, they are first made into a section of rails, when they need to be used, they only need to be strung together, and then put on the sleeper, buckle into the ground, and use a hundred times There is absolutely no problem, This ensured the viable use of the supergiant cannon in conventional warfare.
