The strong kinetic energy of semi-automatic rifle bullets made them prone to ricocheting in narrow tunnels, and after several soldiers were injured by the ricocheting bullets that bounced off the wall, an officer immediately stopped the soldiers' suicidal behavior.

In order to see the situation clearly, they had to light a few more flashlights, and several pillars of light shone into a small pit on the ground, and the Bostonians found that the pit was covered with long iron thorns, and the soldier who had just fallen had been pierced by the iron thorns, and his intestines were rotten and died.

A Boston soldier with poor endurance spat out, and several other soldiers turned their attention to the soldier, but suddenly a smoking grenade was thrown in the dark tunnel. The round grenades rolled all the way to the feet of the numerous Boston soldiers, who had not yet reacted to what was going on, and the grenades had already exploded in the crowd, killing five or six soldiers on the spot.

The Bostonians were frightened, and they scrambled out of the tunnel, ignoring the threat from behind, and the marines hiding in the darkness stood up, and with a single shot of submachine guns, they knocked down several more people.

For the tunnel operation, the soldiers of the 331st Regiment are very experienced, they changed into submachine guns and semi-automatic pistols that are more flexible in the tunnel, and even brought remote-controlled directional mines and a lot of grenades and flashbangs.

"What? It is impossible for the Chinese Empire to have many garrisons here, you have three divisions of troops, and you are still beaten out in such an embarrassing way, you stupid pigs, no more stupid than pigs. Remus roared, he couldn't believe that this island, which was only stationed in a few thousand people at most, had actually destroyed a hundred thousand troops with the cooperation of the navy and air force.

"Immediately order the army to move the field artillery to the mouth of the tunnel and blow up the tunnel for me." Remus roared, he was already furious, the fleet had been delayed on Ville Island for too long, he had to clear this island in a short time, and then develop south or east to occupy more islands, and then put all the land-based planes on the transport ship, as long as he occupied more islands, he would have a better chance of winning in the next battle against the Chinese Imperial Navy.

On Remus's orders, the Army actually transported the 76mm infantry guns to the mouth of the pit that had been discovered, and the Boston artillerymen flattened the barrels, then pushed in a high-explosive shell, pulled the rope and fired it. With a loud bang, the shell exploded less than sixty meters away, and a huge wave of air rushed out of the tunnel, almost killing the Boston artillerymen themselves.

The tunnels of the Chinese Empire are all tortuous, and it is impossible to achieve the effect of artillery attacks, not to mention that they are all built according to the specifications of the main guns of the resistance naval battleships, how can a small field gun destroy it, so the Bostonians returned to the old way, filling this gap that seems to be forever unfillable with human lives, and exchanging numerical superiority for victory.

Chen Shou was lying in the tunnel, holding an old-fashioned Type 94 submachine gun in his hand, although this submachine gun is outdated and rarely equipped in the troops, but in the tunnel, the power of the submachine gun is not too large or small, it is very practical, it not only ensures the density of firepower, but also does not produce ricochet, so this antique weapon has been collected by the soldiers.

"How's it going?" Seeing a soldier who came back with a cat on his back, Chen Shou asked in a low voice, the other party was Qian Feng, a scout sent by their group.

"Nothing, those Bostonians are such fools that they actually tried to bombard the tunnel with infantry artillery, and almost reimbursed themselves." Qian Feng said with a smile, full of contempt for those Boston GIs who didn't have much combat experience. It is no wonder that Boston soldiers with combat experience have been sent to the battlefield on the Western Continent, and now those left in the country are not only the old, weak, sick and disabled, but also the new recruits who have just served, and their combat effectiveness is quite worrying.

"Take care of yourself, be careful of stray bullets." Another person in the combat team, Chen Laoer, who has seven years of military experience, said with a smile.

Qian Feng shook his head: "It's okay, they still can't hit me, just now I fired a few more black guns, this group of grandsons heard the gunshots and were so frightened that they lay on the ground and didn't dare to move, and there were not many people who fought back." ”

Chen Lao Er wiped his gun and said: "They are not suitable for fighting in the tunnel, unlike us who have lived in the tunnel for a long time, and can see things in the dark, they can't compare to this." ”

Chen Shou nodded and said, "Let's take advantage of this advantage and strike hard at the enemy." Didn't the regiment commander say it? We're going to hold the Bostonians down and buy time for the main forces. ”

Qian Feng and Chen Lao Er nodded and said, "We will definitely be able to hold on." ”

The three of them rested for a while, and then walked towards another pit according to the formation of Chen Shou in front, Chen Lao Er in the middle, and Qian Feng behind. The tunnels are crisscrossed and the network of passages is extremely complicated, but the soldiers of the 331st Regiment, who live here all the year round, have no risk of getting lost at all, and they skillfully shuttle through them, striking hard at the dazed Bostonians.

"Hurry up, rush in." An officer brandished a Colt pistol and shouted at a group of soldiers.

"Why don't you go in by yourself, it's so dark inside, and there are Chinese people with black guns." Several soldiers clamored and refused to go in.

The officer also knew that he could not be pushed too quickly, otherwise he would be killed by these men if he caused a mutiny among the soldiers. If only the chariot could advance into the tunnel, then there would be a solid steel barrier, the officer frowned and thought, he accidentally saw the field gun that was abandoned aside, his eyes suddenly lit up: "Hurry up, remove the shield of the field artillery, let's go in with the shield, we won't be afraid of the Chinese people shooting black guns." ”

"yes, that's a good idea." Several soldiers immediately went up to dismantle it, and soon they set off with field gun shields, and seeing their actions, many other Boston soldiers at the mouth of the tunnel dismantled the field guns, and they ignored the artillerymen's obstruction, and each group of people carried a steel shield into the tunnel. Some groups were more careful, and they had two people with sticks in their hands, walking behind the three people carrying the shield, and striking the ground with long sticks so as not to fall into the trap. With shields in place, the Boston soldiers even set up a couple of flashlights for lighting.

"Hurry up." The officer behind shouted impatiently, with the protection of the shield, he was a lot bolder, and he was a little anxious to walk at this time.

"Damn, these guys are not slow in their brains, and they have carried a big iron plate, which is not easy to fight now." Qian Feng said indignantly.

Chen Shou smiled clearly: "Everyone's brains are not all mush, it is normal to think of ways to deal with our black guns, but their methods of dealing with them are not thorough." Old money, you go get trolls. ”

"With trolls? Okay. Qian Feng advanced a few dozen meters backwards, opening an inconspicuous dark door from the wall of the tunnel, which was a place to replenish ammunition and food for the soldiers. Qian Feng still had a lot of ammunition and food on his body, he didn't pick these things, just took a shotgun and a lot of ammunition, and walked back.

With a click, Chen Shou loaded the shotgun with the weapon handed over by Qian Feng, and whispered to the two comrades-in-arms to assign the task: "Old Qian, you go and blind them, I'll attack, Lao Chen, you answer in the back, if there's something wrong, shoot to cover me." ”

"Okay, no problem." The two partners split up.

A Boston team of more than a dozen people got closer and closer, and soon came to a place less than ten meters away from Chen Shou's group. Qian Feng and Chen Shou, who were hiding in the corner, nodded, then took out a flashbang, pulled off the insurance and secretly rolled out.

The flashbang does not explode, and after it rolls two meters, it suddenly flashes with a dazzling light, like a sudden burst of lightning in the dark night. The Boston soldier who had been staring at Qian Feng with wide eyes was blinded, and a stinging sensation came from his eyes, making several soldiers scream.

Taking advantage of the opportunity of the other party's temporary blindness, Chen Shou picked up the shotgun and rushed out, he pulled the trigger fiercely, and a large piece of tiny steel balls sprayed out of the gun, covering an area of several square meters. The field artillery shield was not fully protected, at least there was a gap in the middle, which was used on the field gun to look out.

A large piece of steel ball hit the middle of the shield, and the Boston soldier who was looking out was still rubbing his eyes, trying to recover his eyes blinded by the flashbang, at this time a large piece of steel ball hit him in the face, although due to the distance, he was not directly killed, but a large number of small steel balls were embedded in the flesh, and the soldier who was hurting immediately lay on the ground and screamed.

Hearing the gunshots followed by screams, the soldiers reflexively fell to the ground, and even a few soldiers with flashlights threw their flashlights aside, for fear that they would become the next target. The soldier holding the shield also fell to the ground, and the shield could not stand without help, and it fell directly forward, hitting the concrete floor of the tunnel with a loud noise.

Seeing the opponent's shield landing, Chen Laoer, who was standing behind as a cover, lost no time in throwing a grenade over, and with a loud bang, all the Boston soldiers in a squad were reimbursed.

"Well done, so enjoyable." Qian Feng said with a smile, at this time, the three of them were running in another fork in the tunnel, and since they were wearing special soft-soled shoes, running in the pit would not make too much noise, which greatly reduced their chance of exposure. Because in this enclosed space in the tunnel, any louder noise will produce countless echoes, thus revealing one's own target.

"There's a situation ahead." Seeing a few flashlights swaying in the distance, Chen Shou immediately waved his hand to remind him, signaling the two comrades to stop. Hearing Chen Shou's greeting, they also saw the flashlight, and the two immediately stopped, and the three of them formed a very standard vigilance action back to back, each monitoring one direction.
