The retinue who came to persuade him to surrender was Wen Yong Bo Guchen, whom Zhao Yong and Yang Wei had seen in the Mongol army, and he was also the Fenglei general who met the bald Polo in the tiger skin camp post city in Liaodong.

With Tong Yi's order, a group of guards poured in with a hula outside the door, but to Tong Yi's surprise, they did not arrest Gu Chen, but stood in the room with expressionless faces.

"Don't take down this traitor yet!" Tong Yi couldn't help but be furious when he saw this, and pointed at Gu Chen and yelled at those guards, but those guards still didn't move.

"Brother Tong, you and I have known each other for many years, don't you know what kind of person the little brother is, if you are not sure, how will I come to see you?" Gu Chen smiled slightly, sat on the seat on the side, looked at Tong Yi and said, "Brother Tong, you are a rare tiger general, as long as you submit to Da Yuan, you will be reused, Da Yuan has learned a lesson, and you and I will be in charge of the political situation at that time." ”

"You also took refuge in Beiyuan?" Tong Yi's face suddenly became ugly when he heard this, he knew that Gu Chen had already controlled the situation at the scene, so he looked up and asked Zhang Tao who was standing there, and asked with a cold expression, without Zhang Tao's assistance, Gu Chen would not be able to do this anyway.

"Lord General Soldier, the one who knows the times is Junjie, and now that Dayuan is attacking fiercely, it is better for your lord to return to Dayuan." Zhang Tao bowed his hand to Tong Yi and replied in a deep voice.

"Uncle Wen Yong, do you want to watch the people of Beizhili being slaughtered by the war?" Tong Yi suddenly had a wry smile in his heart when he heard this, he didn't know when Gu Chen bought Zhang Tao, but now it seems that Zhang Tao's rebellion will bring great danger to Daming, and then frowned and questioned Gu Chen, reminding Gu Chen that he was the noble of Daming.

"The younger brother has already said that the former Wen Yongbo is dead, and the younger brother is now the deputy envoy of the Dayuan Privy Council, named Fenglei." The corners of Gu Chen's eyebrows furrowed slightly, and he said disapprerovingly, "Where is there an immortal in the war, as long as Da Yuan enters the Central Plains, there will be no more wars in the two capitals and thirteen provinces in the future." ”

"Ridiculous, when Meng Yuan ruled the Central Plains, the people were not happy, do you want the people of the Ming Dynasty to return to the world where they were bullied?" Tong Yi couldn't help but sneer and retorted coldly.

"Brother Tong don't worry, the Great Khan of Adai and the Taishi of Arutai have decided to reuse the officials who returned to the Ming Dynasty, and do not change the existing laws of the Ming Dynasty, and there will be no situation that Brother Tong fears." Gu Chen laughed and replied methodically, "Brother Tong, junior brother is not embarrassed for you, first wronged Brother Tong to stay here for a few days, and after my Dayuan captures the capital, Brother Tong will be free." ”

Saying that, Gu Chen stood up and walked out of the door, wanting to put Tong Yi under house arrest in the Reverse Horse Pass, after all, the two had a good relationship before, and he didn't want to do things too much.

"Uncle Wen Yong, don't forget, Duke Yiguo and Marquis Zhenwu have already achieved a great victory in Liaodong, and as soon as the war outside the border is over, how will you deal with this brave army?"

Looking at Gu Chen's back, Tong Yi said to him in a loud voice, "In addition, Jiaozhi and Guangxi are changing with each passing day under the management of Zhenwuhou, how do you deal with the Xiaowu army in Jiaozhi?" The emperor worked hard to govern the country, and all the people supported him, why did the Northern Yuan Dynasty enter the Central Plains? ”

Gu Chen's figure stagnated slightly, and then quickened his pace to leave, he naturally knew that it was difficult for the Northern Yuan to enter the Central Plains, so as long as Emperor Xuande could be forced to move Emperor Xuande to Nanjing City, then the Northern Yuan and the Ming Dynasty would have the opportunity to rule by crossing the Yangtze River, and no matter how bad it was, they could rule across the Yellow River.

Zhang Tao summoned the middle and senior generals of the Ming Army in the name of Tong Yi to the conference hall, and put all those generals in prison, and then transferred all the 20,000 Ming troops brought by Tong Yi out of the Fallen Horse Pass.

With Zhang Tao's assistance, not only did the 80,000 troops of the Guanxi Seven Guards pass by, but also introduced the 20,000 Ming troops brought by Tong Yi into the encirclement of the Guanxi Seven Guards, causing the 20,000 Ming troops to become prisoners in a daze.

In fact, in addition to the 80,000 horses of the Guanxi Seven Guards, there were also 30,000 servants led by Tong Yi who entered the Guanma Pass, and under the complicated gaze of the rebels in the Guanma Pass, they passed through the pass and entered the Baoding Mansion in Beizhili unimpeded.

The appearance of the seven guards in Guanxi made Baoding Mansion a mess, and the local people never imagined that the Mongolian soldiers would cross the Fallen Horse Pass.

The wealth of Beizhili naturally far exceeded that of the Western Regions, so the Mongolian soldiers naturally would not let go of such a good opportunity to make a fortune, so they plundered all the way and rushed to the capital with great momentum.

Emperor Xuande was shocked when he learned of this, and the entire capital was shrouded in an atmosphere of panic, no one knew how the Seven Guards of Guanxi quietly passed the heavily guarded, easy to defend and difficult to attack the Fallen Horse Pass, if they attacked the Fallen Horse Pass, at least the capital could get a report of the battle in advance.

Since almost all the troops near Gyeonggi were transferred to Wanquan to participate in the war, the Beijing army in the capital was only about 20,000, and even the guards guarding the imperial city were only more than 30,000 people, which was not enough for the capital with nine gates.

For this reason, Emperor Xuande urgently transferred 50,000 horses from the neighboring Juyong Pass, so that only 20,000 people remained in Juyong Pass, which originally had an army of 70,000.

Emperor Xuande's move was very helpless, because the seven guards of Guanxi crossed the inner Great Wall and forced the Beijing division, he had to transfer troops from Juyong Pass to protect the safety of the capital, in a sense, Juyong Pass has been helplessly strategically abandoned, it is obvious that the strategic value of the capital is much greater than that of Juyong Pass.

At the same time, Jiangwutang urgently moved all the personnel of the suburban battalion of the Xiaowu Army into the capital, and recruited troops from the military households near Gyeonggi, and recruited nearly 10,000 people in a short period of time, plus the remaining personnel of the suburban battalion of the Xiaowu Army, so that the capital had more than 15,000 defensive troops.

In this way, the strength of the Beijing division has 120,000, plus the people in the city are recruited, and it is just enough to defend the city, you must know that the strength of the capital is usually about 300,000, and the current strength is only one-third of the usual.

It is worth mentioning that due to this sudden war, the lecture hall stopped teaching, and its students, instructors, and officials of all sizes were integrated into the army defending the city.

As the leader of the Ming Dynasty, Zhang Fu took on the heavy responsibility of defending the city, and in order to increase the number of troops, he deliberately removed the private soldiers used as guardians in the palaces of the nobles in the capital, and went all out to defend the capital.

Zhang Fu also has a trump card in his hand, his trump card is the thirty Fran cannons and 5,000 arquebuses in the storehouse of the lecture hall, although these weapons were made but not issued down, the reason is very simple, both artillery and musketeers must go through strict training before going to the battlefield, otherwise they will not be able to exert the power of the Fran cannons and arquebuses, and they will be easily captured by the Mongol cavalry.

Although it is impossible to go into battle to fight the enemy, the Franc cannons and arquebuses can be used to defend the city, and all the artillerymen and musketeers have to do is fire cannonballs and bullets.

Therefore, the Xiaowu army in the capital and the instructors and students of the lecture hall began to practice the use of the Fran cannon and the arquebus, fortunately the lecture hall has opened a course on artillery and arquebus, and those students and instructors although it is more difficult to operate the Fran cannon, but they can use the arquebus.

In addition, there were trainers of Franc cannons and arquebuses in the Xiaowu army left behind in the camp on the outskirts of Beijing, which made both the Fran cannon and arquebus exert their respective powers.

When Zhang Fu put in order the defense of the capital and was ready to wait, the seven guards of Guanxi who arrived in the capital did not launch an attack on the capital, but turned around and went north to kill Juyong Pass in the north.

Zhang Fu, who was wearing armor, looked at the Kansai Qiwei who was swaggering to the north to kill with an expressionless face, and the corners of his mouth showed a helpless wry smile, what he was most worried about was that the Kansai Qiwei took advantage of the weak strength of Juyong Pass to attack, and now it seems that his worries have become a reality, and the Mongolian soldiers really went to attack Juyong Pass.

In the face of this situation, Zhang Fu was powerless, if he sent troops to the rescue, it would definitely be in the hands of the Kansai Qiwei, and those reinforcements would definitely be ambushed by the Kansai Qiwei on the way, and the murder would be more auspicious.

At this time, Juyong Pass still had a huge role in guarding the Jingshi, blocking the Mongol army led by Arutai, and once it was breached, the Inner Great Wall would lose its role as a barrier to the Jingshi, and it also made Zhou Zheng's army in Wanquan Dusi fall into passivity.

However, the reality of the situation was more severe than Zhang Fu feared, Juyong Pass was fiercely attacked by the 70,000 Mongol troops sent by the Guanxi Seven Guards in the south and Arutai in the north on the 10th day of September, and both sides used return artillery, so that the defenders of Juyong Pass suffered heavy casualties, and after holding on tenaciously for two days, they were outnumbered, and were breached by 70,000 Guanxi and fell to Juyong Pass.

Huihui cannon is also known as the Western Regions cannon, also called boulder cannon or Xiangyang cannon, it is not the artillery of later generations, but a kind of stone throwing machine, this kind of stone throwing machine is just on the basis of the ancient stone throwing machine to improve, improve, innovate more advanced, more powerful.

In the thirteenth century, in the six-year-long battle between the Southern Song Dynasty and the Mengyuan Xiangyang Dynasty (12671273 AD), the Mengyuan army used the newly developed Huihui cannon for the first time, which brought great damage to Xiangyang City, and assisted the Mengyuan army to force the Song army defenders of Xiangyang City, and then became famous in one fell swoop.

In fact, whether China or foreign countries, there has been a "cannon" for a long time, but it is not a tool for firing firearms, but a kind of combat equipment that uses the principle of lever to throw stone projectiles, also known as 旝, Yunyi, flying stones, stone throwing, etc., and was called a stone throwing machine in ancient Europe.

Before the advent of artillery, the stone thrower (cannon) was an important weapon for both offensive and defensive battles in ancient wars.

According to the Song Dynasty military book "Wujing General Essentials", the cannon is framed with a large wood, the joint is connected with metal parts, and the gun shaft that can be rotated is horizontally placed on the gun carriage.

The long rod fixed on the shaft is called "slightly", which plays the role of leverage, and the one that uses a wooden pole to make a little is called a single one, and the one that is tied together with a plurality of wooden rods as a tip is called a little more, and the more a little count, the heavier and farther the stone projectile is thrown.

One end of the cannon tip is tied with a leather socket to hold stone projectiles; The other end is tied with a cannon cable, and the rope is several zhang long. There are several small cannons, and there are more than 100 large cannons.

Each rope was towed by 12 people. When throwing stone bullets, one person aims and sets them, and the towing cannon man drags the gun rope at the same time to throw the other end up, and the stone bullet in the leather nest is thrown by inertia, and the firing range can reach hundreds of steps.

After gunpowder was used in the military, it was also common to throw fire blankets, poison shells, and explosive bombs with artillery.

The "General Essentials of the Martial Arts" records more than a dozen forms of cannons, most of which are placed on the ground or buried in the ground, and are fixed and fired. There are some that have four wheels installed under the gun carriage for ease of maneuvering, and are called car cannons. There are also cannons whose pillars can rotate left and right to throw stone projectiles in all directions, called cyclone cannons.

The stone throwing machine has a strong stroke in the world's military history, China until the middle of the Ming Dynasty, with the promotion of gunpowder and guns, the Ming army gradually eliminated the stone throwing machine this heavy offensive and defensive equipment.
