He Yilong and He Jin's idea is also very clear, that is, to hold the northern city with the Mu Su Barbarian Rebellion under the command of Po Xi Mu, as well as a large number of white-hat Mu Su Man gathered in the city.

And the two of them led the Han thief team at the head of the camp under their command, and there were two groups of people before and after, with a total of more than 4,000 people, and they stuck to the other gate of Guyuan City, that is, the south gate.

In doing so, on the one hand, Po Ximu and his subordinates can go to fight with the besieging officers and troops first, and try to consume the Musu barbarian population in the city as much as possible.

On the other hand, he was also able to personally block the way for the people in the city to retreat south, preventing this former official army guerrilla Po Ximu from suddenly abandoning the city and fleeing.

He Yilong and He Jin originally thought that Po Ximu would definitely talk to them, bargain, and calculate.

But what the two of them didn't expect was that Po Ximu listened to the arrangement of the two people, and agreed very happily and boldly.

The next day, Yuan Chonghuan, the governor of the three sides, came to the north gate of Guyuan City three miles away, stood on a high post, held a telescope produced by Hexiwu, and looked at the head of Guyuan City and the city.

At the same time, Zhou Yuji commanded his men and horses to cut down large trees on the nearby hills, making stone throwers and siege vehicles.

Yuan Chonghuan knew the extreme importance of artillery to the officers and soldiers, and of course he did not forget to disassemble the artillery from the side wall of the first line of Huamachi and transport it over a long distance.

It's a pity that up to now, the land of the three sides has not been able to be equipped with the kind of Hongyi cannon with a range of up to ten miles that Ningyuan City was equipped with back then.

Otherwise, Yuan Chonghuan would definitely transport them to attack the city.

However, although there was no Hongyi cannon, Yuan Chonghuan and Cao Wenzhao, Zhou Yuji and others who followed Yuan Chonghuan to Guyuan also firmly believed that it was only a matter of time before Guyuan City was captured.

Because Li Banghua's battle examples at Shimen Pass and Hong Chengchou's battle examples in Ningxiang provided Yuan Chonghuan with a way to attack the city with firearms.

In particular, Hong Chengchou's use of a very primitive trebuchet to throw a large number of fierce fire oil bombs at the defending side can be directly applied to the Guyuan City in front of him.

In the early morning of April 19, as soon as the sun rose and shone bright and warm light on Guyuan City, Yuan Chonghuan led a large army to come out of the official camp and set up a position outside the north gate of Guyuan City.

Huang Tingbi, the former garrison of Guyuan Town, who graduated from the first phase of the artillery department of the Huangming Zhongyi Lecture Wutang, commanded the twenty general cannons that had been transferred with great difficulty, and was at the forefront.

After the artillery position, it was followed by the position of ten tall catapults under the personal command of Zhou Yuji.

On the two flanks of the catapult position were the cavalry of Cao Wenzhao and his Wulie battalion and his Mongolian servant army.

Yuan Chonghuan took Mao Yujian, Cheng Benzhi, Wang Yu and other strategists to supervise the battle behind the catapult position commanded by Zhou Yuji.

Yuan Chonghuan's supervising general, He Renlong, led a large number of foot soldiers from the Trilateral Governor's Mansion to guard Yuan Chonghuan's Chinese army banner.

A huge dragon flying phoenix dancing military flag and a trilateral governor's ministry Yuan's handsome banner indicating Yuan Chonghuan's identity, on a high ground in the north of Guyuan City, waving in the wind and hunting, to the Musu barbarian rebel generals in Guyuan City, declaring the great military might of the Ming official army!

Po Ximu, who had witnessed all this standing behind the layers of giant shields at the head of Guyuan City, knew that the attack of the official army outside the city was about to begin, and the will to attack was also extremely resolute.

He himself was born in the official army, and he was a guerrilla of the former Guyuan Town battalion, and many of the people who led the troops outside the city were his old acquaintances.

As soon as he saw the formation they put on, Po Ximu knew that he was about to usher in an extremely tough battle.

At around midnight that day, everything was arranged on the official and military positions outside Guyuan City, and Yuan Chonghuan gave an order, and a burst of creaking sounds began to sound on the catapult position commanded by Zhou Yuji.

This is the sound of catapults being forcefully pulled up by the officers and soldiers under the command of Zhou Yuji.

Immediately after this squeaky sound, Zhou Yuji shouted three times in a row!

"Put! Put! Put! ”

The trebuchet used by the officers and soldiers was a simple return cannon made using the principle of a lever.

It's just that these Huihui cannons, which were made by the Semu people and brought into China with the Mongols, are now fired not as stone cannons, but as huge fire bombs burning with fierce flames.

One by one, huge fire bombs were thrown into the sky, carrying flames, flying hundreds of steps, and then falling one by one.

Some fell at the head of Guyuan City and smashed directly into the crowd at the head of the city, causing a commotion.

Some fell on the wall of Guyuan City, and the fierce fire oil bomb made of clay pottery "banged" and shattered, and the flying fire oil instantly burned the wall into a ball of fire.

Some flew directly over the city and fell into Guyuan City.

After the first batch of ten fierce fire oil bombs were launched, Zhou Yuji observed the landing point of the ten fierce fire oil bombs, and then rode on the horse and shouted loudly to his subordinates, pushing the trebuchet, either forward, or backward, or left, or right, adjusting the distance and error.

When the second round of fierce fire oil bombs was launched again by the torque generated by the lever that was pulled down, ten fierce fire oil bombs all fell on the head of Guyuan City.

Zhou Yuji, who was born in the Jingshi Shenji Battalion, naturally knew the important role of firearms, but he was not equipped with advanced firearms produced by the Jingshi Armament Institute.

Therefore, the use of grenades and fire bombs, which were more readily available, had to be regarded as a regular subject in the daily training of the vehicle artillery battalion and the infantry battalion under his command.

At this time, it was only after a round of calibration, and by the time it was launched again, it had already hit all of them.

In this era, the firing range of the general's cannon commonly equipped by the Ming army was not as long as that of a high-quality trebuchet throwing stones.

Therefore, the Dingyu Town Artillery Battalion led by Huang Tingbi could only carry the general's cannon, load it with scattered bullets, and stand in front of the trebuchet position to act as a cover.

Because of the distance of hundreds of paces, the bows and arrows used by the Musubarian soldiers at the head of Guyuan City could not reach the positions of the officers and soldiers outside the city at all, except for the aimless rain of arrows thrown out at the beginning, they were soon burned by the fierce fire and oil bombs thrown by trebuchets on the city, and they could not stand on the city.

When Yuan Chonghuan decided to take Guyuan Town to move to defend Huamachi, he demolished the few general cannons on the head of Guyuan City, and only left more than a dozen tiger squat cannons fixed on the north and south of the city in the center of the three sides.

As for the range of the Tiger Squat Cannon, it is even more pitiful.

Unless it was a flat shot at close range within tens of paces, unless it directly hit the vital point of the head and face, the projectile fired by the Tiger Squat Cannon fired from the back was simply negligible to the officers and soldiers who were all equipped with at least a wide-brimmed iron helmet and a whole piece of iron chest breastplate.

The first attack of the officers and troops under the command of Yuan Chonghuan outside Guyuan City has always stopped at the steps of trebuchets throwing fierce fire bombs.

Although the real siege of the city has not yet been launched, a steady stream of fierce fire and oil bombs have already frightened He Yilong, He Jin and the generals and colonels of the Musu Barbarian Army in the city.

Although the white-capped wooden barbarians who went to the city to help in the battle in Guyuan City showed high morale and great courage, they were not well-trained sergeants after all.

Most of these Musubarians were small traders, some herders, some farmers.

They just obeyed the orders of the imams to go to the city to help in the battle, and one by one they either kept saying something in their mouths, or shouted inexplicable calls, shuttling between the piles of blazing flames ignited by the fierce fire and oil bombs of the officials and soldiers, desperately pushing the rolling logs and stones that could not smash a single besieger under the city head in a daze.

These people are brave and fearless, but they are all useless.

At this scene, I saw that He Yilong, who had come to supervise the battle, and the Chinese army under his command scolded angrily one by one.
