The explosive bag used by the Xuan army is still filled with granular black powder, which is a kind of deflagration powder processed on the basis of the original gunpowder, purified and processed using a special process, and the explosion effect of granular black powder is only one-seventh of that of TNT in later generations.

Based on the deflagration characteristics of granular black powder that are different from other types of explosives, in order to maximize the power of the explosive pack, under normal circumstances, Xuan Jun excavates a closed space for the explosive pack as much as possible.

Of course, this is not to say that this explosive pack cannot be used directly in an open place, in an open place, the shock wave caused by such a large charge can also affect a living target within a radius of meters, but if you want to exert its maximum power, it is best to use it in an enclosed space.

The soldiers of the 1st Ranger Company were busy digging the pit where the explosives were buried, and because it took a lot of time to warm the ground with a bonfire, there were already some Houjin soldiers in the direction of the enemy camp, escorting the Korean slaves towards this side.

The distance between the two sides was still very far, and the enemy's closest forward camp to Fort No. 1 was also at least 5 kilometers away from here, plus all the slaves could not eat at all, shivering in the cold winter wind, and could not go fast at all, so the soldiers of the sharp knife squad did not rush to retreat after issuing the first warning signal, but continued to monitor the movements of the enemy on the opposite side.

After the Houjin soldiers walked for about a quarter of an hour, one of the middle-aged Jurchens twitched his nose a few times, and then his face changed, and he shouted, "There are a large number of people in the pit. ”

These people's Niu Lu Ezhen stood still and asked the middle-aged man carefully. "Ale-drought, what's going on?"

"Master, it smells of charcoal burning."

Niu Lu really breathed a sigh of relief, "Maybe it's those people who are on duty at night who secretly roast the fire, let's go." ”

Alehan shook his head, "Master, no, the taste is very big, and it is ruthlessly fresh, at least dozens of fires, and those who are on duty at night don't have the courage to use so much firewood." ”

Hearing this, Niu Lu was really shocked, that's right, the trees around him have been cut down, and those firewood are transported from more than ten miles away, specially used to dig pits, each bundle is counted, and these coatings are at most quietly smoked for warmth, and it is absolutely impossible to use them on a large scale.

The Houjin military law is strict, and these people will never dare to do this, unless, unless they don't want to die.

Thinking of this, although Niu Lu Ezhen didn't know what was going on, his years of career as a horse had taught him what caution was.

"Alehan, take two people, ride horses, and go over there to investigate and see what the hell is going on."

"Wow."

The three of them turned over and rode away, and those who remained were not idle, and began to make some preparations, such as winding the bow and arrows, adjusting the knife to a convenient position, and so on.

When he opened a distance of 100 paces from the three cavalry sentry detectives in front, Niu Lu Ezhen waved his hand again, and immediately divided about thirty or forty Jurchen soldiers again, and followed with their horses, but they kept a distance of more than 100 steps from the front.

Niu Lu Ezhen led the remaining dozens of Jurchen cavalry and more than 200 servant troops, and slowly escorted the slaves forward at the rear.

The squad leader of the sharp knife squad was lying on the edge of the trench, looking at the movement on the opposite side, and with some annoyance, he hammered the soft soil that was dug out in front of him, turned around and whispered to Zhao Qingyu, "Company commander, the enemy who came to take over is alert, they sent a sentry and respond, and now it is a three-line formation." ”

Zhao Qingyu gently put the last explosive bag he carried into the pit, filled it with soil, and carefully opened the bamboo pipe seal on the top of the fire cable, and then raised his head to look in the direction of the enemy.

The three cavalrymen immediately came into view, glanced left and right, everyone finished their work, Zhao Qingyu was very satisfied with everyone's speed, seeing that the enemy had entered the firing range, he hesitated a little and measured the distance between the enemy and himself on the three lines.

This distance is exactly a node, if you retreat immediately, there is a certain chance of being bitten by the enemy, but it will delay the speed of retreat, although the probability is relatively small, but it doesn't take much time to directly kill this wave of enemies here, and when the time comes, without such a close tail, it will be safer for your side to retreat.

Thinking of this, Zhao Qingyu made a gesture of preparing for battle, and everyone immediately put the sapper shovel back in their bags, and then took off the four-year rifle from their backs.

Zhao Qingyu quickly ran to the position of the sharp knife squad in small steps, "Try to wait for the enemy to get closer, and then fire." ”

"Understood."

On the other hand, the closer Alhan got to the trench, the more he felt as if he was being targeted by a tiger in the mountains, goosebumps all over his body rose, and under the deliberate control of the horse's reins, his position was changed to the back of the queue, and when the sense of danger in his heart decreased slightly, Alerhan saw the light flickering along the edge of the trench in the distance.

"Someone." Alhan shouted, turned over and dismounted in embarrassment, and fell to the ground fiercely, while there were several dull firearms from the opposite side, and the other two cavalrymen burst out of their chests with a bloody mist, killing them on the spot.

The more than 30 cavalrymen who followed behind immediately shouted and drew their bows and arrows, and rushed to this side, while rushing, they kept throwing arrows to the rain, but because the distance was too far, everyone was lying in the trench, and the protective strength of the steel helmet was reconciled, so it did not cause any damage at all.

On the contrary, those cavalry, when they rushed to a distance of 200 meters, began to fall to the ground continuously, seeing that they were defeated, the remaining cavalry was ready to turn around and leave, but how fast they turned around and reloaded the rifle reload speed, but in just a few seconds, these dozens of cavalry were all killed.

Niu Lu, who was pressing the formation in the back, really whistled, and a cavalryman immediately turned around and galloped in the direction of the camp. The rest of the Jurchens mounted their horses, dispersed at the rear of the entire escort procession, and then brandished various weapons and leather whips, and began to drive the servant army in front of them forward.

The minaries were also very adept, hiding in the middle floor, and the bird-gunners began to light the arquebuses in their hands and then reload the arquebuses, while the minions with cold weapons terrorized the captured slaves and forced them to fight in front.

When these Jurchens were in Houjin, they were very proficient in this trick, and those servant soldiers also realized this trick in the tug-of-war with the Korean guerrilla detachment all year round, and they also used this tactic in the attack on the fortress for more than a month before, so they were completely familiar with it, and there was no trace of jerkiness in using it.

Zhao Qingyu looked at the formation of the enemy, frowned slightly, but in the blink of an eye, it disappeared, and ordered loudly, "Three platoons, four platoons, get on the horse, make a posture of retreating with all your might, and then form a covering formation 200 meters behind." Wait for the first platoon and the second platoon to destroy those cavalry, and then alternately cover the retreat. ”
