By the time Weiss made his last return to the sewer exit, the long chain of explosions on the surface had ended. As you can imagine, the smoke and smoke everywhere, the corpses scattered all over the place, and the mottled bullet marks in the eyes have brought this neighborhood back to a tragic battlefield state.

The essence of urban guerrilla warfare is to come and go without a trace, so that the enemy cannot be guarded. From the time Weiss fired his first shot to the time he was the last to enter the sewer, it was less than ten minutes, and the efficiency was not to be said. The attackers quickly withdrew from the battle, but not in the true sense of the word, and they had to evacuate along the sewers, from the fighting zone back to the garrison at a considerable distance. The Normans did not turn a blind eye to this, and they resorted to a variety of tactics, including tailgating, interception, and more. Considering that the return journey was dangerous, Weiss and the non-commissioned officers selected a number of sewer turnouts and planted explosives in advance in case they were needed. Of course, the technology of detonating explosives by electric shocks has appeared in this era, but the popularity is not high. Before the start of the Battle of Aocheng, the detonators issued were still the regular fuses, and the soldiers generally controlled the timing of the detonation of the explosives through the length of the fuse. In other words, in order for these pre-set explosion points to work, they must be controlled by their own soldiers in close proximity, which is both insecure and restrictive. In order to solve these problems, Weiss and his soldiers adapted measures to local conditions and flexibly used them to create simple automatic fuses with string plus pineball bullets and white phosphorus plus detonators, which greatly increased the number of warning and blocking points.

After a moment's observation in the sewers, Weiss motioned to the guards to set an automatic fuse with string and spinax rounds, which would detonate the explosives hidden in the corners whenever the enemy passed by. However, the city's sewer system was so extensive that even if the entrance was blown up, the Norman soldiers would have to drill directly into the drains in the streets, use ropes to go down wells, or find maintenance channels in neighboring neighborhoods, and the urban guerrillas would not have been able to stop them in this regard.

The bulk of the force had already withdrawn, and the rearguard unit, which was mainly composed of response squads, had a total of nine men, including Weiss, who did not need to carry the war supplies they had acquired tonight, but they were carrying quite a few things: rifles, bullets, a decent amount of spinach rounds, and extra explosives packs. The group followed the surveyed route, walked about four or five miles, and when they reached a sewer fork, they suddenly heard hurried footsteps from another direction.

Weiss hurriedly motioned for his companions to stop advancing, and he came to the fork alone, lowered his body, and quietly peeked in. Although there is no special vision opened, through the shadow of the other party and the light of the shaking flashlight, you can still make a judgment at the first time: it is a Norman!

Seeing that the other party was large in number and menacing, Weiss put down his rifle without hesitation, took out a spinach bullet in each hand, pulled the ring, threw it out, picked up the rifle, leaned sideways against the wall, and shouted: "Watch out for the explosion!" ”

The voice fell, and two deafening explosions came from the fork in the road. Immediately afterwards, a wave of air mixed with the smell of mildew, sourness, and fishiness came to the face. Weiss ignored the discomfort of his senses and organs to this breath, and let out a low "Jackfish bullet, group attack", and then flashed out of his small body to observe the situation on the other side of the fork. In sight, the Normans were dead and wounded, and those who were not dead or injured were lying on the maintenance walkways on both sides of the sewer.

The soldiers behind him had already come up, and Weiss gave the order: "Two people in each group, the first group throws!" ”

Two Union soldiers responded and threw a thunder at the Normans. The Norman soldiers on the opposite side opened fire with a bang, the crisp sound of gunfire amplified in the closed passage, allowing Weiss to confirm their identity.

With a certain amount of combat experience, the Union soldiers already knew how to avoid being hit by enemy guns when throwing mines, and the dark environment of the sewers greatly reduced the shooting accuracy of the Norman soldiers, and the two sets of mines in a row were thrown without pressure. This series of explosions, the impact alone had already shocked the Normans, not to mention the damage caused to them by the scattered shrapnel. By the time the third group of soldiers threw off the mines, the gunfire on the other side of the fork was scattered, indicating that the group of Normans who were hula had been beaten to the point that they had no resistance.

Weiss motioned for the soldiers to pause their attacks, looked over, and shouted in Norman: "Surrender, or die!" ”

The Normans did not answer, but replied with a pineapple bullet.

Due to the uncontrolled posture and force of the bomb, the spinball exploded before it reached the fork, and Weiss and his companions were largely unscathed except for the pain in their eardrums. Since the surviving Norman soldiers chose to continue fighting, they were not polite, and they threw two more waves of thunder as if they didn't want money. In the repeated explosions, the quality of the Aocheng sewer project withstood the test, and there was neither a large-scale wall collapse nor a collapse.

The aftermath of the explosion dissipated, and the sewers were filled with thick smoke that was no more than ten feet out of reach even with a flashlight. Weiss squinted, and in his special vision, there were no ten Normans, and a few who were lucky enough to be alive thought that the smoke of gunpowder had obscured the opponent's vision, so they supported each other and retreated. Weiss did not show mercy to the enemy, and walked directly to the fork with his rifle in his hand, and fired three shots in ten seconds, killing three Norman soldiers who tried to withdraw. Then, with a low shout of "follow me," he led the soldiers through the fork. Although there were no pursuers behind them, they had been delayed here for several minutes, and coupled with the heavy movement caused by the fierce firefight, there must have been many Norman soldiers rushing here, and the best way to avoid being entangled by the enemy was to evacuate quickly.

Under Weiss's leadership, the rearguard detachment hurried and hurried, and it didn't take long to catch up with the large force - on the one hand, they carried the war materials they had obtained that night, and their operational efficiency was affected, and on the other hand, they heard a series of explosions from behind, and they were worried that their commander and the rearguard detachment would need to respond, so they consciously slowed down and prepared accordingly.

After joining up with the large army, Weiss quickly adjusted the manpower allocation, allowing the soldiers who had previously served as the rearguard squad to take over the heavy loads of their comrades, and the soldiers who had walked a long distance with ammunition boxes to replace them in charge of the rear. In order to gain enough time for the retreat of the large army, he chose a blocking point suitable for blasting and blocking the passage on the original route, and personally led the rearguard team to squat here.

After waiting for about a quarter of an hour, the Norman pursuers appeared.

Weiss asked his soldiers to be patient, crouching in the fork in the road out of sight of the enemy, and when the Norman soldiers approached, he threw a large wave of thunder at them, followed by a flurry of machine-gun fire and rifle fire. The enemy's vanguard was almost done, and the explosives planted at the fork were decisively detonated.

These explosives, as powerful as two boxes of pineapple bullets, are placed near the top of the sewer, and they will collapse every time they explode.

Blocking the most direct pursuit route of the Norman army, Weiss quickly rushed to the next blocking point with the rearguard troops. When they arrived, they found another Norman army coming in front of them. The more courageous the Federation soldiers, with their familiarity with the underground world of Aocheng, under the leadership of Weiss, used pineapple bullets and machine gun fire to clear the way, like a surging flood, and beat the Normans, who had always been good at tactical coordination, to the point that they lost their temper. Then, without waiting for the enemy in front of them to reorganize their forces, they took the initiative to detonate the preset explosives, blocking the enemy's path.

Weiss was not satisfied with the fact that he led the rearguard to three successive victories, killing and wounding a large number of enemies and incurring negligible losses on his side. According to the original plan, he should return to the garrison in the northeast of the city with the rearguard troops from the combat area northwest of the city at this time, and get rid of the enemy's tracking with a long march. However, after the battle contact just now, he found that the Norman army was very strong, and there was a great intention to destroy the attackers. In order to direct the enemy's attention in the wrong direction, he ordered his soldiers to make improvised trigger bombs out of spinach bullets and strings, and then made a long, non-stop march directly from the combat area northwest of the city to the center of the city.

After being beaten by the Union army for two nights in a row, the Norman commander certainly did not choose such an inefficient method as a headache and a foot pain. In the sewers beneath the central city, the Norman army also sent troops to search. Before Weiss and the others arrived, the Normans had already engaged in a firefight with the infiltrators of the underworld, and the occasional gunfire explosion from afar, the smell of scorching in the air, and the occasional encounter with corpses were all evidence of the exchange of fire between the two sides.

At a large fork in the road where several main and branch lines intersected, Weiss and his soldiers stopped to make sure there was no enemy activity in the vicinity, and they quickly got to work creating explosive traps with pineapple bullets and explosive packs. A short time later, a group of Norman soldiers came through one of the forks. As they passed through the fork, a trap set by the Union soldiers was set off, and a series of explosions killed half of the Norman soldiers on the spot. After the explosion, the fully seated Union soldiers poured their guns out of the shadows, the only machine gun they had brought with them had drained an entire strip of ammunition, and the riflemen fired at least two magazines, plus one or two spinach rounds each. With such a density of firepower, this Norman force of more than 20 people was wiped out in just a few minutes.

Dealing with this rather unlucky group of Normans, Weiss did not clean up the battlefield, and directly led the soldiers to a relatively hidden fork in the road, and walked half a mile along the fork to a maintenance passage leading to the ground. Above this passage is a building adjacent to the Grumman Building, the main body of which has collapsed, and it is impossible to leave upwards, but it can use the remaining space to temporarily avoid enemies. Arriving at the hidden spot that had been discovered earlier by the scouts, Weiss had his soldiers bring in large pieces of the building's debris and block the maintenance passage from above, creating the illusion that it was blocked by a collapsed building. Next, everyone rested in this cramped but safe space, sorted out their weapons, counted ammunition, replenished their food, and let the large Norman army chase and intercept them nearby, and they did not care at all.
