The ten-day deadline for the Monte Empire had passed, but the Monte Empire had not heard from it at all, but had only built fortifications and stationed heavy troops on the border, in an attempt to rely on strong fortifications to stop the attack of the Chinese Empire.

On April 17, 906, the Ministry of Foreign Affairs of the Chinese Empire officially announced that the Monte Empire had not made any indication within the time limit, and that they had given up hope for peace, so the Chinese Empire was forced to declare war on the Monte Empire.

Just 10 minutes after the Foreign Ministry statement was issued, 560 Kunpeng 1 bombers of the Chinese Empire took to the skies, crossed the border under the cover of 320 Golden Eagle 1 fighters, and began to bomb the Monte fortifications on the border line indiscriminately.

The huge number of 155 mm and 203 mm howitzer groups, under the traction of heavy tractors, achieved rapid maneuvering, and they followed the infantry to the Sino-Mongolian border line.

Under the volley of thousands of cannons, the terrifying power made the Monte Empire's fortifications as fragile as tissue paper, and the Monte soldiers hiding in the positions could only curl up in the anti-artillery holes and shiver, praying that the shells would not fall on their heads.

It's a pity that those Monte soldiers don't know the way, and the heavy artillery unit that is launching the artillery bombardment is just the regular unit of the heavy artillery regiment, and at this time there are two behemoths slowly driving along the railway line.

Under the light of the spring sun, a not too long train came from the railway line in the distance, and the most noticeable thing was the huge black gun muzzle on the back carriage, which was part of the train artillery unit under the Heavy Artillery Regiment of the Chinese Empire.

The railway soon came to an end, as a branch railway near the border with Outer Mongolia, which had previously been used to transport supplies to nearby outposts or to transport goods to nearby bilateral trade fairs. And today it will have an even more important task.

As early as eight years later, after the caliber of naval guns exceeded 356 millimeters, Zhang Hui, the person in charge of the artillery research office, began the theoretical research of a new type of army artillery.

Compared to the Navy, the artillery of the army is very difficult. The army artillery does not have the buffer of seawater, and the recoil of the artillery is all borne by its own buffer equipment, and the requirements for the artillery itself are more stringent. In terms of increasing the caliber, the larger the caliber of the gun, the greater the chamber pressure, which requires a thicker barrel to ensure that the chamber will not explode, and such a design will greatly increase the overall weight of the gun.

Weight is not a problem for battleships, but it is a big problem for the army, if the weight is too large to be towed forward, then no matter how large the caliber of heavy artillery is meaningless. Zhang Hui tried his best, and in terms of field artillery that could be used with the army, he could only make a 203-millimeter heavy gun, which was still based on the fact that the Chinese Empire had excellent artillery steel, which could greatly reduce the weight of the artillery.

This road was impassable, so Zhang Hui naturally found another way, and soon the huge transportation and carrying capacity of the railway attracted him. After research, Zhang Hui found that the load-bearing capacity and carrying capacity of the railway were outstanding, which allowed him to build larger artillery, and after repeated demonstration and research in the artillery research laboratory, the Monty Python 1 train gun was born.

The caliber of the Python 1 train gun reached 280 millimeters, the muzzle length was 215 meters, the total length of the train was 311 meters, and the total combat weight was 218 tons. For the development of this train cannon, Zhang Hui has put a lot of effort into the design of this cannon, the design of this cannon is quite classic, simple and lightweight vehicles, outstanding ammunition handling equipment and reloading mechanism are quite simple and easy to use, so that the firing speed of this giant cannon can reach two rounds per minute.

The muzzle velocity of the cannon can reach 1,120 meters per second, the firing range can reach 62 kilometers, and the warhead can penetrate more than 3 meters of reinforced concrete walls, and the explosion power is very huge.

Of course, excellent performance also comes at a price, in order for this gun to work, it needs almost a thousand people in its service, and all the entire heavy artillery regiments also have fifteen such guns. And such a train, at this time, is stopping at the end of a makeshift railway.

"General, everything is ready." A regimental commander ran up to a middle-aged man in a general's uniform and reported. This burly middle-aged man wearing a general's uniform is none other than the third-level general Xiao Jun.

Xiao Jun from the head of the independent artillery regiment after more than ten years, all the way to the commander of the heavy artillery regiment, in the military system of the Chinese Empire he has been inconspicuous, low-key so that the outside world is rarely noticed, but the military is very clear that although the troops led by Xiao Jun have never really fought, but has not interrupted all kinds of high-demand training, more importantly, the artillery unit he is in, almost the cradle of the entire Chinese Imperial Artillery.

In addition to being a strategic artillery corps, the Heavy Artillery Regiment has always played a role similar to that of the 1st Air Force Medium Altitude Division, and all the artillery units of the Chinese Collar in the early days were born in this unit. After the establishment of the military academy, every cadet who graduated from the artillery academy will also enter this artillery unit for one year of advanced study before being assigned to other artillery units.

With such a strict training system, the artillery of the Chinese Empire is extraordinary, and at the same time, Xiao Jun has become the father of the artillery of the Chinese Empire and even later, so although outsiders do not understand, within the military, Xiao Jun's status is still very high.

Xiao Jun approached, looking at this mighty and majestic cannon, his heart was also full of excitement, he has been working in obscurity all these years, but who can know that in his heart, the part that has been suppressed belongs to the blood of soldiers, every time he looks at the brilliant results of his former old comrades-in-arms, his heart is also full of loss.

Today, the heavy artillery regiment was finally ordered to attack, which made Xiao Jun extremely excited, and this train gun, which has always been loved by him, can finally exert its true power. "Have the coordinates of the Air Force been reported?" Xiao Jun looked at the cannon and asked the regiment commander beside him softly.

This regiment commander is obviously in charge of this train gun, and he is also very excited at this moment, and when he heard Xiao Jun's question, he immediately replied: "It has been sent, and the soldiers have adjusted the artillery to shoot Zhuyuan according to the coordinates." ”

Xiao Jun nodded: "Then launch it, keep in touch with the air force at any time and correct the ballistics." ”

With the order to fire, the two-meter-high shells were slowly pushed into the artillery by the ammunition feeder, all the artillerymen wore headphones, and the others quickly evacuated the scene. There was a loud bang, even Xiao Jun, who was standing in the distance, felt as if there was a five-magnitude earthquake under his feet, and the heavy barrel of the gun slammed into the back seat, pushing the base of the train gun back several meters away.

The Monte soldiers, who were waiting in the rear, suddenly heard a howling sound from the air, and the howl was so piercing that it was like a roar from hell, that the soldiers who heard it almost wanted to gag. A huge warhead smashed into the Monte army's position from far and near, and the violent explosion set off a raging wave, turning all the nearby soldiers into smoke and dust.

As the dust gradually fell, a large crater with a diameter of more than 30 meters was revealed. Around the crater, there were large groups of Monte soldiers who had been shaken to death, and in the crater, there was no trace of any position or man. For a moment, the nearby battlefield seemed to fall silent, and all the Monte soldiers stared blankly at the shocked scene in front of them.

"Report to the regiment commander, according to aerial reconnaissance, the shell deviated one hundred and fifty meters to the south." A communications soldier reported.

"The muzzle of the gun is raised three degrees and the reload continues." Hearing the report of the signal corps, the regimental commander commanded loudly.

The artillerymen were well-trained to do their job, trying to adjust the attitude of the guns, while the mechanical loader made an overwhelmed creak and slowly hoisted another shell onto the conveyor belt, waiting to be placed in the chamber.

"Good job, the error of the first shot is already very small." Xiao Jun smiled and encouraged.

The regiment commander wiped the sweat from his forehead and said: "Commander, just take a look, I will definitely knock out their underground fortress, but the firing speed of our cannon is a little slow, and it can only be fired once in thirty seconds." ”

Xiao Jun said with a smile: "You can be content, the new Giant Python 2 train gun is about to be equipped with troops, I heard that the cannon is fired once every five minutes, it is good." ”

The regiment commander was surprised: "The shooting is so slow, how big is the caliber of that cannon." ”

Xiao Jun smiled slightly and said: "I only heard that it is bigger than the naval gun, as for the specifics, I don't know the details, let's talk about it when it is equipped." ”

"What? Two ammunition warehouses on the front line were blown up by opposing artillery fire? When Marshal Bayangar of the Monte Army heard this, he almost thought that he had misheard.

"Aren't the ammunition depots on the front line protected by two-meter-thick reinforced concrete walls, and they are all underground fortifications, how can they be destroyed by artillery fire?" Marshal Bayange angrily questioned, thinking that someone must be joking with him.

General Dabur said with an embarrassed face: "Marshal, this is true, the opponent's artillery is very powerful, it is said that the crater alone is more than thirty meters wide, and our reinforced concrete fortifications can't stop it at all." Although he said this, in fact, when he first got the news, he thought he was dreaming.

Marshal Bayange slammed the table and said: "Bastard, could it be that these guys moved the battleship to land, how can such artillery appear on land." Although he was reluctant to admit that the current Monte Empire had lost its position as an opponent of the Chinese Empire, all he could rely on was the support of the Cossack Empire.
