Driven by the Warlords, waves of new annexes rushed to the camp with screams. In the front were the artillery and grenades of the Banju army, and in the rear, the sword and axe hands of the Mongolian army. If you rush forward, you may die, if you retreat, you will definitely die, and if you run away, your wife and children will suffer because of the punishment. The desperation in their hearts contorted the faces of the new annexed soldiers, and they rushed to the camp like moths to the fire, and were harvested like crops under a sickle in the sound of dense explosions. It is now late August, and the rice in the fields will be harvested in about ten days. It's just that after this bloody battle, most of these charging new annex soldiers can't eat the fragrant new rice.

Newland's attrition tactics slowly paid off. Thousands of corpses of the new annexed army not only filled in the three trenches in front of the Banshu military barracks, but even piled up a thick layer under the earthen walls, so that the able-bodied could step on the corpses and jump into the barracks. Before the war, all the mines planted by the Banshu army under the earthen wall had been detonated, and the artillery and muskets had become extremely hot under the continuous firing, and they had to stop firing. The original four-line fire network consisting of artillery, mines, grenades, and muskets now only has grenades left. Fortunately, the Banshu army had a sufficient number of grenades, and they were good at hand-to-hand combat, so they still firmly held the camp. On the other hand, the heavy casualties demoralized the new army, and the rain and blood made the front of the Banshu camp slippery and muddy, making the offensive even more futile.

Seeing that the firepower of the Banzhou army was gradually weakening, Niu Ling ordered the whole line to attack, and the troops attacked in three directions, preparing to break the Banzhou camp in one fell swoop. To the north of the attacking camp was still the new annex army, and to the east was the Mongol Han army. The west side of the Banzhou camp was facing the east gate of Shenjian Castle, and the defenders led by Liu Cheng attacked on all fronts. Due to the distance between the Mongol army camp and Shenjian City, there was no anti-artillery trench dug in the southern part of the camp, and if there was a large-scale attack, it would be bombarded by the artillery of the nearby Perak army camp. Based on the above reasons, Niu Xuan did not send heavy troops to attack the south of the Banzhou military barracks, but sent a small number of dead soldiers from the dark passage of Shenjian City to the earthen wall, and when the defenders of the camp were attracted to the other three earthen walls, they broke into the camp in one fell swoop.

The Mongol army struck out. Facing the enemy surging under the pressure of black pressure, Yang Bangxian felt quite pressured. Unlike the new annex army that attacked before, which only held swords, shields and simple ladders, this time the Mongolian army even pushed shields and chariots, and carried a lot of giant trees to move forward slowly. Shields can block grenade fragments and musket fire, and improvised walls of the barracks will crumble under the onslaught of heavy siege engines, making them impossible to hold if they are allowed to get close. It's just that these siege weapons are so large that they can't advance through the trenches, so they can only move slowly on the ground and become targets for artillery. Naturally, he was well aware of this risk but had no choice but to pray that the rain would fall a little heavier and the night would be darker, so that the Thunderbolt artillery would not be able to shoot and aim.

Even if the light artillery of the Banshu army did not stop firing due to overheating, it was difficult to destroy the siege equipment of the Mongol army, and at most kill and injure the soldiers who pushed the equipment. To destroy these siege weapons, it was necessary to have the heavy artillery of the ship. At that moment, Yang Bangxian sent someone to ask Zan Wanshou to open a cannon, and ordered someone to light a bonfire on the low wall. In fact, there were already many torches on the low wall, and he did this not to facilitate the killing of the enemy, but to allow the warships in the river to more accurately judge the direction of the camp. Although Zan Manshou had already ordered the gunners to set up a fire blockade near the Banshu barracks, the wind and waves on the water would make the warship sway, and the night was dark, so the gunners' firing operations were very prone to errors. The so-called "a slight miss, a thousand miles away", he did not want to make a mistake in the judgment of the navy, so that the warship shells fell on the heads of his own people.

Liu Quanquan only left 200 people to guard the east gate, and personally led the defenders of the whole city to attack the earthen wall west of the Banzhou army camp. Before leaving the city, he had sent the captain of his own army to lead the most elite 100 dead soldiers to sneak outside the city through the secret passage, preparing to break into the Banzhou military camp and set fire. In addition to the ignition material, each of the soldiers carried a can of fire oil. The fire oil was sent by Niu Ling to the city of the Divine Arm for the purpose of defending the city. As long as there is a fire, the soldiers of the Banshu Army will inevitably be in chaos, and if they do not escape, they will also die in the flames of the burning camp. In order to ensure the success of the sneak attack, the soldiers were all dressed in black, their faces and naked parts of their bodies were also painted with charcoal ash, and they wore straw sandals, and walked quietly. It's just that their actions have been hidden from the Thunderbolt Army's secret outpost near the dark passage. Zan Wanshou predicted that Liu Quan would inevitably repeat his old trick and sneak attack through the secret passage, but he didn't know when it would be carried out, so he ordered someone to closely monitor the area around the secret passage early. It is said that the exit of this secret passage is in the dense forest under the cliff, surrounded by tidal flats and reeds. It was a hot summer day, and there were not only mosquitoes and even blood-sucking locusts, which made the Thunderbolt army outpost ambushed here suffer enough.

Just when Liu Quan's dead soldiers, under the cover of reeds and wild grass, took advantage of the rumbling cannons and the earth-shattering shouts of killing, and secretly marched towards the Banzhou camp in the distance, the Thunderbolt army also moved. The death squad of the Thunderbolt Special Battalion was also a hundred people, and they silently followed the enemy's footsteps to the side of the dark passage, and sent a few people to explore the way first. This dark passage can only be passed by one person, and there is a very steep stone staircase at the foot, and the daredevils are carrying a large number of grenades and ammunition, and it is very difficult to climb with heavy loads. In this narrow passage, if you are attacked, you will not be able to fight back at all, and you will only be wiped out. Several warriors who explored the path groped step by step, and finally climbed to the top of the secret passage, and were pleasantly surprised to find that the heavy wooden gate leading to the city was actually hidden, and the two defenders outside the door were stretching their necks to look at the battlefield under the mountain with a murderous sound. On weekdays, this wooden door is not only locked with iron chains, but also topped by several boulders, which cannot be blown open without gunpowder.

After quietly eliminating the two guards, the Thunderbolt death squad rushed up and took advantage of the explosions and shouts of killing at the bottom of the hill to the east gate. At this moment, Liu Quan's 200 defenders who stayed at the east gate were looking down at the battle situation under the mountain with relish, and were bombarded by a sudden grenade behind them, and they suffered heavy casualties in an instant. Many defenders jumped off the city wall in panic, but the walls of the Divine Arm City were so tall that those who jumped were either killed or injured, and only a few lucky ones limped and fled in the direction of Liu Zhen. After taking control of the eastern gate of the Divine Arm City, the Thunderbolt daredevils sent people back to report the news while carrying huge trees and stones to completely block the city gate. Although they carried a large number of grenades and ammunition, it was obviously impossible for more than 100 people to defend the fierce counterattack of the Mongolian army.

Under the order of Zan Wanshou, the soldiers of the special battalion have long been waiting for the day. Seeing that the sneak attack on Shenarm City was successful, the remaining 400 soldiers of the special battalion entered the city through the secret passage. They carried with them a large number of grenades, muskets, ammunition, and even fire oil - captured from the city of Xuzhou. Unfortunately, the tunnels were too narrow to bring light artillery into the city. However, although the special battalion only has light firearms, because its soldiers are very elite and have plenty of grenades and musket ammunition, it is not difficult to hold the city for a while.
