A lot of work was put into the construction of this stone wall, and a strong gate like a city gate was built on the wall, and the wall battlements and other defensive facilities were readily available, and a trench was dug in front of the stone wall, although there was no water in the ditch, but it was filled with pointed wooden piles, and the stone wall was not straight, and a sharp corner was built on each side of the gate to protect the gate. The stone wall was just like that, cutting off the way for the officers and troops to advance.

Now that you have marched so far, you must attack it all at once. Ren Xianglong knew that he was not reckless this time, but asked the officers and soldiers to camp not far from the stone wall, and let the soldiers prepare siege equipment, while he came to a place not far from the stone wall and quietly looked at the stone wall, thinking of ways to attack.

On the stone wall, Zhang Chu was also observing outside, the official army was menacing, it seemed that the information he had obtained before was accurate, there should be three thousand people, much stronger than the security army. Fortunately, there is the advantage of the terrain, otherwise it would be very difficult to block the officers and soldiers.

A few days ago, he sent to Jindong to keep an eye on the movements of the official army, and sent back a message that the official army might attack the security army, and the number of officers and troops dispatched should be about 3,000. After receiving the report, Zhang Chu immediately mobilized in several counties, leaving the forces of guarding, and the other armed forces were mobilized, and there were only 1,500 members. Although the number of officers and soldiers is only half of that of the officers and soldiers, as long as they plan well and the heroic fighting of the team members, they will definitely be able to defeat the enemy.

In the past two months, the number of craftsmen who came to Zhongyang to look for work increased, and the factory in Zhongyang has been working day and night for more than two months, producing more than 100 qualified flintlock muskets. There was also a large amount of gunpowder produced in the factory, and Zhang Chu was finally able to carry out firearms transformation on the security army.

He followed the official army all the way to spy and finally figured out the direction of the official army's attack. Zhang Chu led his men all the way to enter the preset position before the enemy, and fought and retreated, delaying the enemy's attack. Unexpectedly, this Ren Tongzhi was also a fierce man, who was repeatedly attacked but unmoved, and attacked all the way here.

Ren Xianglong Tongzhi was also very bitter in his heart, this errand had fallen on his head was already very unlucky, and when he came, he hoped that two months had passed, and the thieves had already fled, and it would be over with the soldiers to go through the motions. The hateful thieves not only did not flee but also resisted step by step, killing and injuring a large number of officers and soldiers, and if they lost the battle, their career would be over, and more than ten years of hard work would be in vain, not to mention that they could not even keep their heads when they were promoted. It's nothing to die a few soldiers, the key is how to give an account to your boss. Looking at the stone wall for a long time, Ren Xianglong still figured out a little clue, the thieves ran away after a few hits, they must be small in number and afraid of the dead, but the loss of the official army was caused by the sharp firearms, for the official position Ren Xianglong decided to fight again, if the thief can be beaten away this time, it can also be called the three battles and three victories, the thief must have been running, and the official army is advancing step by step.

Early the next morning, Ren Xianglong gathered the generals at all levels into his big tent, reprimanded them harshly, and ordered them to urge the soldiers to move forward in the next attack.

The officers and soldiers were ready and opened the camp gate, and the attacking team lined up in front of the stone wall, the artillery pushed forward and forward, and the soldiers were nervously busy preparing to set up artillery positions within the firing range. But at this time, they were hit in the head, and the artillery position of the official army was shelled by the security army, and the security military first pulled the artillery up a small hill behind the stone wall, and condescendingly opened fire on the artillery of the official army.

This is not in line with the rules at all, the artillery of the Ming Dynasty is a solid bullet, and it is very difficult to use a big iron ball to hit the artillery position thousands of kilometers away with the technology of the Ming Dynasty. It might as well be used to attack the men who form a dense formation. But things are so strange, the security army not only did that, but also did a good job, after a few rounds of landing closer and closer to the artillery position of the official army, there was a round of several shells directly hit the position, overturning two artillery companies at once and wounding a few soldiers who opened artillery.

This is all thanks to Zhang Chu, who survived in the era of counterfeiting, and in the military exercises of that year, in order to look good, it was a more civilized method to test the impact point in advance. The kind of person who planted explosives under the target is simply brazen. Before the war, Zhang Chu asked the artillery to measure and test fire at the place where the enemy might set up an artillery position, and recorded the data.

The artillery was dispersed before it could open fire, and Ren Xianglong immediately ordered the supervising team to step forward and force the artillery to return to the position and open fire, while ordering the whole army to attack immediately, and the officers and soldiers pressed all their strength without the slightest temptation.

All kinds of siege equipment and people poured into the stone wall, and the guns and cannons on the stone wall poured ammunition out of the wall, and the archers also threw sharp arrows into the ranks of officers and troops outside the city, and the dumb fire of the enemy artillery reduced the pressure on the security forces on the stone wall. The numerical superiority of the officers and soldiers played a role, many officers and soldiers fell on the way to charge, more officers and soldiers rushed to the side of the trench, and at the same time rushed up with many soldiers carrying mud, the corpses of soldiers and bags of dirt fell into the trench, the trench was filled in a road leading to the stone wall, the ladder was erected on the stone wall, the security army threw the rocks and logs from the stone wall, but this could not stop the attack of the officers and soldiers, the officers and soldiers who climbed the ladder were getting closer and closer to the wall, and the security team members guarding the wall threw down the wine jars one by one. The shattered jar of wine was accompanied by a splash of liquid, and a pungent smell came out, "The thief has no stones!" Some officers and soldiers shouted, and all of a sudden the morale of the officers and soldiers was greatly boosted, and more people rushed to the stone wall and desperately climbed up the ladder, ignoring the wine jars that kept being smashed from the wall and the gasoline processed by Zhang Chu flowing on the ground. Several torches were thrown down the stone wall at once, and the flames were everywhere, and the bottom of the stone wall became a living hell at that time. The screams overpowered the shouts of killing, and one by one the humanoid fireballs ran on the battlefield, and then fell to the ground, and the officers and soldiers behind retreated despite the resistance of the warlords, and were attacked by various long-range weapons on the stone wall during the retreat, leaving behind the wounded and corpses on the ground, and the fierce flames burned all the stones red, and some of the corpses in the fire were burned to only a pile of ashes.

Ren Xianglong stared blankly at the hell under the stone wall, forgetting to stop the retreating officers and soldiers, and Ren Xianglong and other officials were also coerced and had to retreat. The officers and soldiers retreated until they were out of range of artillery fire before they stopped, stabilized their positions, counted the casualties, and found that more than 500 officers and soldiers were killed in just one attack, and more than 1,000 were wounded to varying degrees, and the entire contingent had lost the strength to fight again. Ren Xianglong hurriedly ordered to return to the previous barracks to prevent the security army from taking advantage of the situation to attack, and it was also a dilemma for a while.
