As a veteran, Cheng Du naturally mastered the four major tactics of infantry, and blasting was one of them. Of course, he knew how powerful it would be for twenty kilograms of explosives. It was enough to blow up a five-room mansion, and 200 kilograms of gunpowder could blow up a rammed earth wall of about a meter thick, and the person was blown to pieces and could not find the residue. Two hundred kilograms of gunpowder were thrown into such a small mountain village at one time. The scene should not be too spectacular.

The artillery team re-adjusted the shooting angle and continuously fired at enemy outposts, fortresses and other targets on Guishan Mountain. The strong explosion impact of explosive packs was produced. Wherever they passed, whether it was a fortress built with stones or a sentry tower built by giant trees, they were all blown away and razed to the ground. The surrounding trees were also affected and fell to the ground, just like a hurricane by the sea, becoming riddled with holes.

"Charge!" Cheng Du seized the opportunity and ordered the charge to be blown. All the officers and soldiers of the battalion attacked Guishan, but they did not suffer the fierce resistance as expected.

When each department rushed towards its respective targets according to the preview, within three meter radius affected by the shell explosion, he could not stand the living person at all. Those who died were often ragged. However, it was not because the matter was urgent that they did not have time to put on their clothes, but because the armor was torn apart by the artillery fire. The living person was also ashamed with dust, his eyes were dull, and he murmured in his mouth, "It's so scary, so scary..." and he was already scared and lost the idea of ​​resisting.

The battle lasted less than two quarters of an hour and ended quickly. It was so smooth that it was very disappointing. It was not like a war, but easier than a drill. They were more like cleaning the battlefield and collecting the enemy's corpses. Cheng Du did not dare to be careless. After sending a warning force to the mountain pass to the north, he sent a signal to ask the follow-up troops to follow up. He seized the time to build fortifications on the back of the mountain and switched to defense to block the enemy from the northeast and ensure the smooth passage.

"Commander, the enemy's camp in the west of the city sent reinforcements and approached the mountain pass!" Just as Chengdu organized officers and soldiers to step up the arrangement of fortifications, a correspondent soldier came to report.

"Oh, it's coming so fast!" Cheng Du picked up his telescope and looked towards Xiangyang City. He saw enemy troops coming out in a large camp in the west of the city. About a hundred cavalry rushed towards the mountain pass, with dust and smoke rolling behind him, and it was impossible to see how many people were. He looked south again, and his troops were moving north while driving the road, and they were also advancing towards the mountain pass, but due to equipment, they were slow to move. However, no enemy was found in the southeast direction.

"Each one team left behind a defense, and all the rest came out of the mountain pass to block the enemy's troops. They must not be allowed to occupy the access road." Cheng Du knew that it was difficult for a single warning team to block the cavalry's charge. He immediately assembled troops and turned to the north to defend, and at the same time ordered the communications soldiers to immediately seek help from the rear.

When Cheng Du led more than 300 people to the mountain pass, the enemy was approaching. They had no time to build fortifications, and even piled up the simplest earth walls. There was a flat mountain outside the mountain pass, and there was no terrain that could be relied on. He could only use the road as the basis point to launch a linear front to face the enemy and block the impact of the enemy cavalry.

"Mortar, shoot!" When the enemy cavalry rushed into 150 steps, the mortar team of Chengdu Minjian camp began to shoot.

‘Boom, boom…’ As the shells exploded in front and behind the enemy cavalry, the enemy cavalry fell off their horses. However, there were only six mortars in the mortar team. Although they had increased the speed of fire to the fastest, it was still difficult to stop the impact of the enemy cavalry, which caused them a moment of chaos, and the enemy cavalry resumed their formation and rushed towards them quickly.

"Hundred-selves guns fire!" The cavalry's impact was very fast, and it was approaching 130 steps in an instant. After Cheng Du ordered the mortar to fire, he immediately issued an order. At present, each of the Song infantry troops was equipped with a hundred-selves gun to increase the fire density. They fired shots with a shooting range of two meters wide, but the secondary loading was slow. Even so, the volley of more than ten hundred-selves guns caused more than 20 cavalry casualties to the enemy, slowing down their impact, but that was all.

"Fire, bayonet!" The enemy cavalry approached twenty steps forward, and they also began to shoot arrows, trying to open a gap in this weak defense line. Cheng Du also knew that without the strong support of the artillery, the musket had no time to reload within a hundred steps after firing, so two commands were issued at the same time.

‘Bang, bang, bang bang…’ With the sound of command, the soldiers in the first row started fire and fired, and then quickly retreated and installed bayonets. The soldiers in the second row and the third row repeated the movements of the front row, shooting in turn, retreated and bayonets.

‘Boom, boom, boom…’ After the three rounds of shooting, the enemy cavalry had approached less than forty steps. The soldiers in the fourth row did not shoot, but stepped forward and threw the grenades in their hands into the enemy group that was galloping.

"Charge!" The Song army formulated a variety of tactics against cavalry against cavalry, including the method of dealing with the sudden encounter when the troops on both sides are basically equal. It requires the maximum development of firepower in a short period of time and the maximum damage to the enemy, so as to gain the initiative in later melee battles. Cheng Du perfectly interpreted this tactic. After giving the enemy cavalry six consecutive rounds of firepower strikes, it had been lost more than half, and the formation became sparse and messy. He ordered the attack.

Infantry and cavalry are at a natural disadvantage when fighting, but when retreating, they will be chased by cavalry. Everyone knows that without terrain advantages, two legs cannot run four legs, and retreating or escaping can only die faster. The casualties in the war are often caused by hunting during retreat, so the fight may survive.

Even though the enemy cavalry had lost more than half of it, it still had an advantage for the infantry without any barriers to cover it. The powerful impact of the war horses was not something that people could bear. However, Cheng Du knew that he had no way out and they wanted to buy time for the arrival of the subsequent troops. Once the mountain pass was lost, the enemy infantry that followed him would flock in, and the troops of the remaining city could not be stopped.

"Kill, kill, kill..." Cheng Du roared with a spear and took the lead in meeting the enemy cavalry that was speeding towards him, but he did not choose to resist head-on, but misstepped to the left of the war horse, making it difficult for the enemy cavalry to cut the knife. At the moment of intersecting, his bayonet had stabbed into the abdomen of the war horse. The war horse was in pain, and the man stood up and threw the cavalry under the horse. Before he could struggle, he was immediately assassinated by the Song army following him.

Cheng Du was also staggered under the impact of the war horse, but he had already pulled out the bayonet, turned his head to avoid the iron bones that were smashed by the enemy cavalry that rushed over, and lifted the gun and stabbed it into the weak point of the enemy's armour behind the waist, and knocked him down. However, a soldier who was following him could not dodge and was knocked away by the still-running empty horse.

"Go forward, don't retreat!" In just a few breaths, the enemy cavalry had penetrated the weak front of the Song army. Cheng Du glanced at the battlefield, and his side had paid a heavy price for the short confrontation. At least 30 or forty people could no longer stand up. Fortunately, the enemy cavalry had not yet been asked for it, and there were still twenty cavalry left. He stopped the soldiers who were about to turn around and pursued them again, and gathered the team to face the enemy infantry that rushed up.

"Get a small formation and fight to the death without retreating!" Cheng Du kept roaring loudly while reorganizing the formation. He understood the principle that the brave men won when they met on a narrow road. The remaining cavalry passing through the formation was no longer a concern. As long as they fought with the enemy infantry, they could only watch the battle. As long as they could block the enemy infantry, they could not reverse the situation even if the enemy cavalry rushed into the valley.

"Fight to the death, fight to the death!" At this time, the advantages of the Song army soldiers after strict basic training were revealed. Although they had fought continuously and suffered huge casualties, they still instinctively formed groups in groups and formed a formation with adjacent groups, forming a seemingly loose but actually tight formation, shouting to fight to the death and face the enemy.

The two armies soon collided in a narrow passage less than twenty feet wide. One side wanted to drive the other side out, and the other side wanted to block the other side back. The fierce battle broke out instantly, with the sound of the collision of swords and guns, the roar of fighting hard, and the howling of the wounded dying, mixed together, forming the grim laughter of the god of death. Both sides wanted to kill each other.

"Kill, kill!" Cheng Du no longer knew how many enemies he had stabbed, but he felt that the enemies in front of him were dense, as if he could never kill them. He kicked away the stabbed enemy, pulled out the bayonet, and blood splashed out, making his eyes confused. He raised his hand and wiped it, looking around him, and he didn't know which group of people he had changed. He didn't dare to think about it, hoping that he would just be washed away.

‘Bang!’ Cheng Du pulled away the spear that stabbed the comrades beside him, turned around and smashed the enemy with a buttstock. The soldier stepped forward and stabbed the enemy to death. The two of them once again covered each other back to back, facing the enemy who was rushing up again. At this time, only the comrades around them could rely on, and everyone supported each other to survive on the battlefield.

‘Boom, boom, boom…’ After all, the forces of the two sides are very different. Under the pressure of the enemy, the pioneer battalion is difficult to maintain the front line, and he can only delay the enemy’s attack through small assaults during the battle and retreat. And with the continuous attack of the enemy, they are no longer supported and fall to the edge of the collapsed formation. At this moment, suddenly, a few loud noises came from the enemy group, and the smoke of gunpowder rose and flesh and blood flew everywhere. A large area of ​​space appeared in the advancing enemy formation.
