But all the tribal warriors who have been on the battlefield have learned the power of the Ming army's standard equipment thunder, and they are afraid of these gadgets, seeing that the dozen or so big guys on the ground are sparks and green smoke, the first reaction is the giant thunder, although it has not exploded yet, but it can make up what terrifying lethality will be after the explosion, but it is impossible to dodge.

The gap of more than 20 meters looks quite wide, but the feet are full of broken bricks and gravel, and there are a large number of horse corpses and human corpses, if you are unlucky, the war horse may lose its hooves, people are thrown away, and then trampled into meat cakes by countless iron hooves, and it is charging at full speed, there is no way to stop, or turn the horse's head, you can only desperately charge forward, impacting the dense spear formation of the Ming army.

Boom Boom Boom ......

More than a dozen packs of explosives exploded one after another, the burst of fire and billowing smoke instantly filled the entire gap, and the cavalry of the Jin Army who rushed in was also completely destroyed in an instant, and the powerful shock wave even caused both sides of the broken wall to collapse again, several musketeers who stood too close fell to the city, and more than a dozen musketeers were killed and injured by the iron balls and gravel fired everywhere, or fell backwards, or fell down to the city.

The soldiers who laid out the spear array in front had a large shield to cover and cover, only a few unlucky soldiers were injured, taking advantage of the gap where the iron cavalry of the Jin Army was cleared, the wounded soldiers were carried down by their comrades, and the soldiers behind quickly rose up to complete the spear array.

"Beat, beat me hard."

He Renlong roared loudly, inspiring his subordinates to kill the enemy fiercely, although he threw down more than a dozen packs of explosives to clear all the dozens of golden soldiers who poured into the gap, and helped the spearmen who were hard in the front to relieve the pressure, but it was only a few breaths, and the iron cavalry of the golden army poured in like a tide, so that people didn't even have time to breathe, so they could only shoot desperately and throw thunder desperately.

Under the intensive rain of bullets and thunder explosions one after another, pieces of golden soldiers fell down with a scream, but they did not retreat in fear, but saddled their horses and Yue'an, fought back with a bow, and desperately attacked the spear formation of the defenders in front of them.

Although the spearmen on the front had the help of friendly troops, but under the crazy impact of the iron cavalry of the Jin army, the spear array was staggered, and even was once chiseled into the formation.

"Brothers, hold steady, hold on for a while and you can withdraw, hold on!" The political work officer was hit by an arrow in the shoulder socket and thigh, and he did not retreat from the line of fire, but continued to stay in front of the battle to command, and boost morale.

It is precisely because of his brave spirit that he was wounded and did not retreat, so that the soldiers who were afraid of the reason gritted their teeth and supported it, and the iron cavalry of the hard anus Jin Army rushed wildly, and they stubbornly held the frontal defense line without losing.

"Inspector Hong is here with reinforcements."

Suddenly there was a loud cheer behind the sky, Hong Chengchou led the reinforcements to arrive in time, a large number of musketeers poured into the city to fight, the first simple fortification was also built, and the soldiers and civilians were piling up the second simple defense line.

The spearmen and shield soldiers at the front could finally retreat, but because of the chest-high sandbag wall behind them, there were only enough small openings on both sides for one person to pass through, and the retreat speed was very slow, and the spearmen in front had to continue to withstand the crazy attacks of the Jin army's iron cavalry.

Then there were reinforcements sent by Zu Chengxun, he sat on the head of the west city to command, heard a loud noise in the direction of the north city, did not know what happened, but there was a strong sense of uneasiness in his heart, and immediately ordered the general to lead an army over, if there was any bad change, immediately reinforced the He Renlong Department who was guarding the north city.

"Throw the thunder, throw it to the old man desperately, and blow up these rabbits!"

Hong Chengchou climbed to the top of the city surrounded by the guards of his own soldiers, and saw the dense Jin army frantically pouring into the gap, and immediately ordered the soldiers in the city to throw thunder to relieve the pressure of the spear array on the front.

One after another, the thunderbolts with green smoke smashed down from the city like no money, smashed into the cavalry of the Jin army like hailstones, exploding clouds of fire and gunsmoke, and also killing and injuring a large number of the cavalry of the Jin army who were frantically attacking.

The pressure on the spearmen at the front was reduced a lot, and they slowly retreated while carrying the crazy attack of the golden army's iron cavalry, and column after column of soldiers retreated behind the fortifications, and the soldiers in front of them retreated more slowly and step by step, until there were only three columns of spearmen left, and the pressure dropped sharply.

The gap more than 20 meters wide was full of dead horse corpses and human corpses, blocking the passages, and it was easy for the horses to stumble and fall when they rushed in, and the cavalry of the Jin Army, which was charging frantically, had to postpone the attack, galloped under the city wall, suppressed the musketeers in the city with riding bows, and covered the infantry to clear the obstacles.

The pressure of the Ming army defending the city was greatly reduced, and they calmly shot the golden soldiers under the city with a row of guns, and blew up the golden soldiers who dared to rush close with a thunderbolt.

Taking advantage of this gap, all the spearmen safely withdrew to the rear of the fortifications, and the last to retreat was the political work officer with arrows in his shoulder socket and thigh, who was extremely weak due to excessive blood loss, and was forcibly carried on a stretcher by the medical guards and sent down for emergency treatment.

Ordinary soldiers rushed to the front as cannon fodder, and the officers hid in the rear to command, but those officers of the New Army and political workers were the opposite, fighting at the forefront like them, being wounded and not retreating until they died in battle, which made people sigh, and at the same time aroused their enthusiasm and fighting spirit.

Although these officers of the New Army and political workers were very strict during the training, they could not stand it, but after the training, they chatted and talked with them, ate and lived with them, did not have the slightest superiority and privileges, greeted them with warmth, taught them to read and write, and helped them write letters to their families.

The offensive and defensive battles for the gap are still continuing, the Ming army defending the city no longer has to bear the terrible impact of the Jin army's iron cavalry, the pressure is greatly reduced, the musketeers of the front line rely on the chest-high simple fortifications, calmly shoot, with a dense rain of bullets to shoot the Jin soldiers who rushed in, when there are more gold soldiers, they throw thunder and thunder, and blow down the enemy in pieces.

"Stop throwing debris."

Hong Chengchou, who was in command at the head of the city, saw that the frontal defense line had been stabilized, and the second line of defense was almost stacked, and he suddenly remembered some things mentioned by the emperor in the letter, and had a bold idea, ordering the soldiers and people to stop throwing debris and pile up the gap.

The war is a game of comprehensive national strength, burning money, the customs are sparsely populated, the tribesmen live on grazing, do not produce, lack of materials, the population base is small, and one less dies, usually rely on burning and looting to replenish resources, the emperor's ban on the border has been sealed and the tribes outside the border are replenished with more materials, and the strategy is to hold the border passes, kill and injure a large number of enemies, and consume the war potential of the Jin army as much as possible.
