Generally, the steel gates of large bases are made of thick and hard secondary steel armor, and are usually divided into two layers, the inner and outer layers, and the middle layer is the power unit that opens the gate. At this time, the outer layer of the steel gate in front of Hao Yi had cracked a large crack that was five fingers wide, revealing the complex power device inside. While the outer layer of steel armor is strong enough to withstand the bombardment of small-caliber rapid-fire laser guns, the inner layer is not as strong.

"Blow up the door?" The major asked puzzled, "Didn't you just try it?" This kind of base gate is made of next-generation steel armor, and ordinary gun grenades can't work at all, do you have a better way? ”

"Of course it didn't work just now, but now it's different!" Haoyi pointed to the crack in the door and said, "Chief, look, although this gate has not been fully opened yet, and the left and right doors have not been completely disconnected, the gap exposed in the middle is enough for us to find a way to blow it up!" ”

"What do you mean?" The major still seemed to be a little confused, frowning and puzzled.

"My method is simple!" Haoyi seemed to be confident, slapped the door and said, "As long as we make good use of the nail gun in our hands, it is enough to tear this door crack into a big hole!" Although the Nail Gun's armor-piercing spike bullets can't do much damage to this gate, we can use the armor-piercing effect of the spike bullets to focus on the attack. And at the moment when the spike armor-piercing bullet tore through the gap in the gate, and with the grenade fired immediately after it, we were able to make a hole in the gate! ”

"This, is this going to work?" The major was still a little uneasy about Hao Yi's almost unbelievable idea, and asked worriedly.

"Sir, we don't have much time!" Haoyi Zhengse said: "Instead of being chased around the mountains by those dogs, it's better to give it a go!" ”

"What are you talking about? Dry! Hu Erpang on the side was already a little impatient, muttered, and was about to pick up his rifle and shoot at the gate.

"What's the panic? It is necessary to concentrate several spike guns and attack at a single point at the same time to have a chance of working! Haoyi glared at Hu Erpang and scolded: "When did you become so anxious, a foodie?" ”

The major groaned slightly, looked back at the rest of the officers around him, and saw that they had no objections, so he slammed his fist on the gate and said, "Damn, it's inevitable to die left and right, let it go, fuck it!" Hull, go and call all the brothers who have rifles in their hands! ”

The captain, Hull, agreed, and hurried away to gather the soldiers with rifles in hand. The rifles in the hands of these expeditionary soldiers were dropped by the rebel marines when they fled the valley in a hurry. Originally, there were a total of fifty or sixty rifles, but the group of fifty or sixty soldiers of the expeditionary force who had withdrawn earlier had more than forty rifles, and only eighteen rifles remained in the hands of Hao Yi and others. After adding the seven spike guns in the hands of Hu Erpang, Catherine and others, there are only twenty-five in total.

Although Hao Yi said that only ten rifles should be able to blow up this gate, but for the sake of insurance, he still gathered all the rifles. The riflemen were divided into two teams, one with 12 rifles in their hands and 13 in grenade firing mode. Hao Yi carved a palm-sized circle with a dagger in the center of the toothed door, telling the riflemen to aim before firing.

"Ready!" When they were ready, everyone withdrew far away, and the riflemen also withdrew to a safe distance twenty or thirty meters away from the gate, and the major, acting as the commander, waved his hand and shouted: "Fire!" ”

"Da Da Da!" The first group of half-crouched riflemen opened fire first, and a shuttle of spike gun armor-piercing bullets slammed into the mark that Hao Yi had drawn.

"Bang bang bang!" Half a second later, the riflemen in charge of the grenades fired a volley of grenades. "Boom!" The power of the thirteen grenades exploding in unison was also considerable, so that the others on the sidelines only felt a shaking of the ground, and the stone wall where the gate was located was also littered with rubble, as if there was an earthquake.

After the smoke cleared, a large hole with a diameter of about one meter was opened in the middle of the steel gate. The inside of the cave was dark, and without a light source, it was impossible to see behind the door.

"Two fat, come here!" Hao Yi rushed to the entrance of the cave, took a look inside, turned his head and beckoned Hu Erpang, who was wearing land armor, and asked him to turn on the tactical spotlight on the CMC armor and shine his head into the cave. By the bright light of the spotlights, I saw that behind the door seemed to be a circular tunnel with no end in sight, and the walls of the tunnel were covered with a layer of thick steel armor, inlaid with various pipes, etc.

"Could there be some ambush in there?" The major who came over looked at the tunnel and frowned worriedly.

"I can't care about that much!" Hao Yi said to the major in a deep voice: "Sir, I need a few volunteers, follow me to explore the road first, you take the rest of the people, follow us to enter." ”

"Good! Hull! The Major groaned for a moment, then turned to greet his men. According to common sense, a corporal can only make suggestions at most, and he can't speak to a colonel-level officer in such a tone, however, maybe it is an extraordinary period, or maybe the major acquiesces to Hao Yi's leadership position, and the major does not have any dissatisfaction with Hao Yi's rude behavior.

In addition to the twenty-five spike rifles, Haoyi and the others now have only seven pieces of marine armor captured when they were in the field hospital before. The heavy and sturdy land armor with three defense functions is the only heavy equipment that Haoyi's people can take out. If there really is an ambush in that tunnel, then I am afraid that only the team members wearing land armor will be able to get away with it.

After hurriedly discussing, Haoyi took Hu Erpang, Zheng Shaolei, the captain officer named Hull and the other three non-commissioned officers, put on CMC armor, and got into it first. Catherine was escorted by several female soldiers, followed by the major and the rest of the soldiers. Before they all entered, the major carefully asked the soldiers to find some rubble to re-cover the gate and the opening. It may not help, but it's better than just exposing the gate and the opening.

After entering the tunnel, the biochemical system inside the armor showed that the air quality in the tunnel was good, but Hao Yi and the others still didn't dare to open the mask carelessly, God knows if there would be any mechanism to release poison gas here. The seven of them lined up in a line, turned the tactical spotlights on the armor to the brightest, and grabbed the spike gun in their hands and touched it step by step.

The tunnel gets steeper and steeper the further you go, as if it is going deep underground. Haoyi and the others groped carefully for a while, and then they encountered a three-way intersection, in this dark tunnel, they couldn't distinguish between the southeast and the northwest, and everyone didn't know where to go for a while.
