The Battle of Tonghui River seemed to have consumed all the courage of the Yuan army, and the expeditionary force's efficient way of killing people required the Yuan army to take some time to digest and accept. After the Yuan army suffered a fiasco, more than 20 Meng Yuan generals knelt at the door of the Privy Council, and then the Seventh Prince came out and said with a smile: "Are you here to force the palace?" The generals of the Yuan army lowered their heads and said in unison: "The guilty ministers have been entrusted by the emperor, come to receive the punishment" The seventh prince hurriedly came down and bent over to help the general Li Chahan (Zhao Min's father) up and said: "Victory and defeat are common things in soldiers, generals must not blame themselves, get up, get up, come in and say." The Seventh Prince dragged the generals up and invited them into the Privy Council. When the Seventh Prince and the generals sat down, the Seventh Lord said in a sincere tone: "The generals have worked hard in the battle the day before yesterday" As soon as the sentence fell, the generals who had just fallen on the chair knelt down again. The Seventh Prince hurriedly said: "What is this, everyone, get up and speak, do you still want this king to help you once" After the generals got up, the Seventh Prince continued to say: "I know very well about the war the day before yesterday, everyone didn't expect the thief army to be so fierce, I saw the emperor yesterday, and the emperor was very annoyed by this." Li Chahan and the others knelt down again and said: "They all blame the ministers for not fighting well, which frightened the emperor", and the seventh prince said with an embarrassed expression: "This, this, this." Don't kneel at every turn, let me finish my sentence." When these people sat down again, the Seventh Prince said, "What did you just say?" Li Chahan reminded: "The emperor is very angry" The seventh prince said: "Yes, yes, yes." The emperor was furious, but after I talked about it, I finally let the saint know how you fought bloody battles on the front line, and the emperor's anger disappeared. Li Chahan said: "Thank you for interceding for us" The seventh prince said, "Don't thank me, I want to thank the saint for his insight, but (the tone of these two words is aggravated)" Li Chahan was just about to continue kneeling down when he was held down by the seventh prince, and the seventh prince said: "The general don't force me to tie you to a chair, listen to me" The seventh prince said: "Although the saint tolerates us, but we must not live up to the saint's heart, can you tell me if I can protect the emperor's safety" These generals looked at each other, At this time, Li Chahan said: "Tell the Seventh Prince, we will fight to the death to protect the emperor's safety." The Seventh Prince said: "Alas, don't mention dying in battle, the emperor still needs you." I heard Hua Er Buchi talk about it last time, why didn't I see him today? A marquis of Wanhu said: "Tell the Seventh Prince, General Hua'er Buchi, he has died in the battle the day before yesterday" The Seventh Prince sighed and said: "He is a loyal minister" and then he said to these generals in an inquiring tone: "Is it feasible for General Hua'er Buchi to put forward the plan to cut off the grain route of the thief army" Without waiting for these generals to answer, a herald ran in panting and said: "Report to your lords, there is a situation outside the city."

Now a kilometer outside the city, the Combo army camp, a huge thing has been built. This is the big killer that Cheng Pan personally escorted to the north this time. A giant cannon with a caliber of 18 meters and a caliber of 425 mm. This steel behemoth weighs 75 tons with a single barrel, this gun uses the Armstrong breech gun loading, the bottom adopts a rotating base, and adopts a hydraulic pipe retreat mechanism, this hydraulic pipe retreats each time the tube retreats due to insufficient air tightness processing, so each tube retreat needs to be re-injected with water to reset it, which is more troublesome, this re-entry system is not for fast tube retreat, but to slow down the strong recoil force on the base after the gun is fired.

After Cheng Pan formulated the plan to ascend to the north 6, he has been thinking about what to use to give the Yuan Dynasty an indelible impression. Cheng Pan first considered the machine gun, but this thing consumed too many bullets, the battle the day before yesterday consumed a total of 26o million bullets, but just the fifty machine guns consumed nearly one-tenth of the fire in five minutes. This is not yet a republican government with a high level of industrialization, and this method of war cannot be fought. Since you can't use machine guns to create a sea of corpses and blood, then try to break the sky. Large-caliber fortress guns are known as the key research directions of the Republic Steel Production Department. In order to make this large-caliber artillery, the republican government provided absolute material and manpower support to the No. 1 Iron and Steel Plant, which has the most advanced technical force.

One of the most important 100-ton hydraulic presses was conquered for this huge artillery project. Hundreds of steel pipes are connected to the high-strength pressure plate of this hydraulic press, each steel pipe is divided into two sections, and a thinner steel pipe in the upper part is tightly inserted into the thick steel pipe in the lower half. This is a rigorous project, the steel group provides high-strength steel, and the mechanical group in order to get qualified parts, each part is ground out by the old workers little by little. The 100-ton hydraulic press was finally born.

Of course, in order to make a 325 mm cannon, this kind of murderous thing is not just a matter of a hydraulic press, and the No. 1 Iron and Steel Plant specially built two steelmaking furnaces with a one-time ironmaking of 50 tons. The mechanical group is responsible for building the giant air hammer.

Finally, in the No. 1 Iron Works, the product of the highest industrial achievement of the Republican Territory was born. This is the most powerful artillery of the fifteenth century, Cheng Pan thought to himself: "Such a large artillery may maintain the reputation of the largest caliber cannon for twenty years, right?" "It is true that this artillery, made with the support of an industrial system, maintained its reputation as the heaviest and strongest artillery for a long time, but the title of largest caliber was defeated by the mad Turks a few years later. In 1452 the Turks created a giant mortar with a caliber of 1o66 mm and a length of 7.92 meters, specially designed to fire stone shells weighing up to 544 kg. Well, the world is crazy.

Cheng Pan used the sea space to transport all the parts of this giant cannon to southern Taiwan, and this class cannon was quickly erected, and three days later, the giant cannon began to be test-fired. Of course, there is nothing to say about the power of the 425 mm caliber cannon, but for the sake of the life of the barrel, the cannon only tested ten shots, allowing the artillery to initially grasp the approximate number of this artillery. But it was these ten training bombs that made the Gaoshan tribe in the mountains of Tainan collectively go out of the mountains and surrender.

Now a second wave of people who have seen the power of the cannon is about to appear. On the second day of the erection of the fort, the actions of the communist army attracted the attention of the Mongols at the head of the capital, and the seventh prince climbed the seven-meter-high city head, saw the barrel of the giant cannon shining with metallic luster in the sun when it was erected, and said: "What is this" A general said: "It looks like a huge artillery" The seventh prince immediately laughed and said: "This must be a scare plan of the thief army" "The prince is wise" The seventh prince seemed to accept the sycophants around him leisurely, but a trace of melancholy appeared in the depths of his glasses.

Cheng Pan relied on his ability to mobilize 1,000 people in the army to build a fort, the parts of the cannon were assembled modularly and then transported with the ability to climb in the process, and finally after the erection of a large pulley crane, a turret built by dozens of tons of boulders was miraculously erected in two days, and after three days of charcoal drying, lime and glutinous rice juice connected the boulders, and the cannon could be fired.

After the giant cannon was successfully erected, the Communist Army began to name this giant cannon, and names such as Shenwei Cannon, Sky Breaking Cannon, and Mountain Opening Cannon all popped up, and finally Cheng Pan dictated this name. Cheng Pan said that the reputation of the weapon depends on the effect of his swing in a certain battle, Cheng Pan decided to let this giant cannon shine in the history of this time and space, referring to the way the German army named the cannon that bombarded Paris in the original time and space, Cheng Pan thought for a while and pointed to this giant cannon and said: "This cannon is called Beiping." The term Beiping Cannon has since been recorded in the history books.

On January 25, 1349, a huge hot air balloon was raised over the Communists' positions, a vision that once again caused a riot on the city walls and five kilometers away by the Yuan army, who after a series of blows, believed that the Communists had a background behind the crusade. Now the thinking of the low-level soldiers of the Yuan army is that the communist army has now received the help of the gods, but their immortal heaven has not reacted yet, could it be that something happened to the immortal sky, coupled with the high-pressure policy of the generals of the Yuan army not to discuss, the atmosphere within the Yuan army is becoming more and more tense. Yu Hai, who boarded the hot air balloon this time, is the child who hooked with Cheng Pan a few years ago, and now he has grown up. Cheng Pan specially came to ask him when he recruited the hot air balloonist, and under the temptation of flying, Yu Hai entered the hot air team, which can be regarded as the fulfillment of Cheng Pan's promise to him to fly.

After Yu Hai passed down the number jù through the observation of the optical instrument on the hot air balloon and calculated the number jù observed on the ground, the Beiping cannon made a creaking and screeching steel friction sound under the pull of 300 horses, and the rolling axis of the iron ball at the base rotated. The cannon turned its muzzle towards the enemy battalion five kilometers away. The movement of the cannon once again attracted the attention of the people on the city wall, and everyone in the defenders of the capital watched intently as the cannon made its next move.

The structure of the Beiping cannon is similar to that of the Armstrong cannon in the original time and space, and some problems with the Armstrong cannon have also plagued the gunner, the most important thing is the placement of the bolt, the original heavy bolt requires a specific pulley group to operate, but now there is Cheng Pan, a pervert with a snatching force of five tons. One qiē is much easier.

A heavy infantry anti-personnel shell was stuffed into the breech, followed by a spacer and a projectile pack, which, after the bolt was attached, ignited. "Boom" An air ripple appeared around the muzzle of the cannon, and the person who was 100 meters away lost his hearing for a short time after the loud noise, and then there was a long period of tinnitus, which took a long time to recover.

The huge cannonball flew out of the muzzle of the cannon shining with huge fire and smoke and flew extremely fast to the hundreds of thousands of Qinwang troops in the distance, the huge bullet fell to the ground, the spring firing pin hit the shell at the moment it landed, igniting the six hundred kilograms of picric acid inside the shell, the huge force instantly tore the steel shell, the scorching gunpowder gas drove the two hundred kilograms of iron beads in the cannonball to shoot around to form a death zone with a radius of 1oo meters, although the cannon was powerful, it caused the death of a hundred people, But that's not what the cannon does. Under this kind of natural disaster-like blow, the heart of the Yuan army within a radius of at least five hundred meters collapsed. This shelling was like a bullet hitting the glass, and although the contact surface between the bullet and the glass was small, it caused absolute damage to the glass, and the Yuan army, which seemed to be strong at this time, was now as fragile as glass. In the expeditionary force's unstoppable posture of advancing all the way invincible, coupled with the high-pressure rule within the Yuan army, the Yuan army, which had lost confidence in victory, was forced by its superiors all the time to bombard the camp under the bombardment of Beiping artillery. The generals of the Yuan army quickly mobilized their troops to quell the chaos, but ten minutes later, under the fast cannonballs of Cheng Pan's cheating, the Beiping cannon fired again. Another huge bomb fell down, killing more than a hundred people again, and then causing a bombing of the camp area, at this time, the Houyuan army had begun to know that this terrifying blow came from an expeditionary force five miles away. But there was nothing they could do, and fifteen minutes later the cannon fired again. At this time, after the correction of the first two shells, this time the cannon hit Richard's banner at once, and at this time, his father and Wang Baobao were quelling the camp roar that appeared in broad daylight, so they escaped. But this shell, in addition to killing people, was the last straw that crushed the hearts of the Yuan army. Large-scale collapse in the Yuan army camp opened an unstoppable appearance. More than 200,000 troops were forced back by the Beiping artillery and three artillery, which is called a legend in the war.

When the hot air balloon spread the news of the collapse of the Yuan army in the distance, the 6 Seas ordered the Beiping cannon to be aimed at the Dadu city wall. After 6 Hai finished the order, he began to say complacently: "In the Tang Dynasty, Xue Rengui had 'the general three arrows to set the Tianshan Mountain, and the strong man sang a long song into the Han Pass', and after a hundred years, I should evaluate the enemy army with six seas and three artillery."

At this time, Cheng Pan didn't know about the 6 seas, and after getting the instructions of the 6 seas, Cheng Pan began to cooperate with the next filling. The Seventh Prince's whole process watched the epic three shots of the Beiping cannon, and the huge orange-red fire bloomed in the Yuan army camp, setting off a shock wave. The Seventh Prince also witnessed the collapse of the more than 200,000 yuan army at the same time, and for this kind of weapon that was beyond their imagination, the Seven Princes and the Yuan Army at the head of the city were like watching a science fiction disaster movie. The Seventh Prince said dejectedly: "Back then, we used Huihui artillery to break through Xiangyang, and now the Han people use this thing to deal with us Mongols, is this retribution?" When the people around heard this, they were silent.

The head of the capital was silent for a while, but soon the Mongols on the head of the city began to turn around after the three cannons of Beiping, and the Yuan army did not want to act in the thriller himself. The chaos began, and the Yuan army at the head of the city immediately disorganized the order, and it was difficult for people to maintain order in the face of natural disasters, and the damage caused by the 425 mm caliber cannons was almost the same as the effect of natural disasters. Tens of thousands of people died in a Wenchuan earthquake, and it is normal for tens of thousands of people to die in World War I and World War II with a random war with the roar of giant artillery.

As the soldiers at the head of the city pointed at the muzzle of the cannon trampled on to escape, the guards of the Seven Princes opened the way with machetes while shouting: "Let the Seven Princes go first". These pro-soldiers were highly skilled in martial arts, and they quickly carried the Seven Princes down the city wall and away from this dangerous area by slashing and trampling on people.

After the cannon is turned, the cannon is repositioned by filling the retractor with water. Cheng Pan replaced the cannon with another shell, a pure high-explosive shell. "Boom" shells fired from the muzzles of the cannons in a straight line towards the Dadu city wall a thousand meters away. The high-explosive shell pierced into the earthen wall 2o meters later, and the spring fuse ignited the delay lead after the shell entered the earthen wall, so the shell did not explode at the first time, and the infantry who were still struggling on the city wall at this time only felt a shock to the city wall, but they didn't have time to rejoice for the rest of their lives after the disaster, and the delay fuse burned out. Eight hundred kilograms of picric acid burst into the earthen wall, masonry and clods of earth flew out, and the brick cracks of the city wall with a range of several hundred meters were shaken by the blast wave of earth smoke, and a large number of bricks fell off on the city wall within the range of two hundred meters of the explosion, and in the center of the explosion point was a yellow dust mushroom cloud with a diameter of fifty meters. Five minutes later, the dust cleared, and a thirty-meter-long gap appeared in the wall. The communist army 1,000 meters away clearly observed the power of the Beiping cannon at close range, and I don't know who started, and the communist army began to shout excitedly: "Orthodox avenue, supreme power." Of course, the power of the Beiping cannon is not over Cheng Pan brought a total of 50 shells of various types for the Beiping cannon this time, and the show began to continue to shoot three high-explosive siege bombs after the giant cannon stopped bombarding, at this time Guo as a messenger held a white flag to the Yuan army position, the Yuan army appeared this messenger, several Yuan troops surrounded it, and the communist army envoy Guo showed his identity, at this time the Yuan army wanted to tie the envoy back. At this time, the envoy of the Communist Army, Guo, said: "I am negotiating on behalf of the Communist Army, I can ask the commander of our army to build the number of attacks with our level weapons tomorrow, are you sure you want to tie me up?" As soon as these words came out, the Yuan army, which was originally going to tie up Guo, did not dare to act. The centurion who greeted the envoy of the communist army said: "Then please wait for a while, sir" After a while, the Yuan army sent an envoy to welcome Guo in. Guo was surrounded by heavy and brought into the capital after walking a long way, and finally met with the seventh prince, the seventh prince said with the smile of the uncle next door: "What is the so-called matter of your envoy coming" Guo Tao took out a piece of paper from his arms expressionlessly, and the entourage of the seventh prince took the paper and checked it, and handed it to the seventh prince, the seventh prince was immediately shocked when he saw it, this is the map of the capital of the Yuan Dynasty. The Seventh Prince's face turned cold and said, "What is the matter with your army? Guo said: "This is the map of Dadu that indicates the place and time we will strike in the past three days." Please be prepared. The Seventh Prince looked at the map again, his face turned blue and said: "You deceive people too much" Guo said: "The words have been brought, please send me out of the city" The Seventh Prince said: "Your envoy is tired of the journey, it is better to rest here for a while" Guo Tao said with a smile: "If I go out of the city too late, our general will not follow this map." The Seventh Prince's eyes flashed with cold light, staring at Guo, but Guo always remained indifferent, the Seventh Prince was defeated in the end, and the Seventh Prince said, "What do you want?" Guo said: "After the first strike tomorrow, if you are willing to send people out of the city to negotiate, the strike plan can be suspended" The seventh prince said: "Can the location of this first strike be changed?" Guo Dao: "I am only responsible for the order, not for negotiation" After several persuasions, Guo was still unmoved. Before leaving, Guo came to say: "It's better to let the prime minister come to negotiate" The seventh prince asked strangely: "Why" Guo said: "Our supreme commander is here, he once promised the prime minister to come to the capital to talk with him at night." ”

Half an hour later, Guo returned to the army. With the merits of this negotiation and the merits of being Fang Guozhen's military division last time, the rank became the head of the regiment.

At this time, the Seven Princes were busy in the city, and they wanted to take the emperor out first, because the first blow tomorrow was the Yuan Dynasty Palace.

The next day, the Beiping cannon moved again, which was also the last time it moved in this war, Cheng Pan prepared a special yellow phosphorus bomb for the Yuan Dynasty palace this time, and Cheng Pan only made three of them. After the cannon fired, a fire broke out in the imperial palace of the capital, and this fire emitted poisonous smoke (white phosphorus is poisonous) that could not be extinguished. The last shot of the Beiping cannon completely forced the Yuan Court, and the expeditionary army told the nobles in the capital that you are not safe anywhere.

The negotiating team of the Yuan Dynasty came out.
