Half an hour later, the group unloaded their suits, sorted out their equipment, and left two people to guard the camp, and came to the entrance of the underground shelter. The reason why Pen Fun Pavilion www.biquge.info Iron Slag dared to take the risk of using the Thunder Hammer to recruit them was because of the urgency of the situation, even if he and the Black Pig King were strong, they were always weak and difficult to save people, and partly because these people were all Blood Eagle's subordinates, and he believed that a follower of an Earthwalker would not be someone who had no faith. From another point of view, if these people are timid and afraid, he will not dare to show the thunder hammer.

Looking at the dark and deep mountain tunnel, Alva, who had explored twice before, brought a wooden box, took out paper and pen, drew a sketch on the spot, and explained to the iron slag the general structure of the underground shelter. For the most part, the design of the shelters is much the same, although there are some special structures, but after all, they are a minority.

After entering the tunnel, the first area is usually the isolation area, followed by the assembly room. The main function of the quarantine area is to check and disinfect to prevent people entering from carrying viruses or other harmful substances; The function of the assembly room is to wear radiation protective clothing, organize equipment, and check the location of weapons.

In the past, the assembly room was an action hall, and its main function was to assemble personnel, handle procedures, assign tasks and a series of other matters. Action halls are often connected to elevators, power generation rooms, and air filtration centers. Among them, the power generation room is the heart of the underground shelter, and without electricity, the entire shelter will be paralyzed. Therefore, the generator set is generally located in a shallow soil layer for easy maintenance and moisture-proof.

Below the first floor, there are usually a series of living facilities such as activity rooms, living cabins, restaurants, medical cabins, and material warehouses. Further down is the factory area, where there is a water purification center, a food processing center, a pharmaceutical manufacturing center, etc.

Normally, the exploration team will have priority access to the power room and attempt to start the generator set. If you have access to electricity, you can turn on the lighting and ventilation systems to make it easier to explore.

Therefore, the path of this operation was through the tunnel into the quarantine area, then into the assembly room, then into the operations hall, and finally into the power generation room.

After explaining the structure of the underground shelter, Alva analyzed the characteristics of the living dead.

The strength of the living dead is extremely strong, and their tissues are unusually tough, close to the body of steel, and the damage that gunpowder bullets can do to them is limited. The weakest of the living dead also have the power of the Golden Primary, but they move more slowly, have poor eyesight, and only have decent hearing. As long as you don't get close and don't make a sound, you won't alarm them, so many people will choose to bypass them during exploration.

However, since the goal of this operation is rescue, not exploration, it is best to clear out the living dead along the way, so as not to cause trouble during the retreat.

Alva's suggestion was approved by Iron Slag, and after discussion, the group set off.

A few seconds later, several beams of light shot out of the flashlight, sweeping back and forth through the tunnel, illuminating the dark space. It is a straight tunnel with alloy steel plates embedded with willow nails overhead and on both sides, and a hollowed-out iron mesh underfoot. Along the way, the place is fairly well preserved, and there is almost no trace of rust.

After about a kilometer, the group came to a round metal gate. At this moment, the door has been opened, and through the beam of the flashlight, you can see that there is a large cylindrical space inside. After observing the door for a while, two agile insects cautiously walked in, and after some investigation, they confirmed that there was no danger, and beckoned everyone in.

There were two pale-skinned humanoid corpses lying on the ground, and when you looked closely, the muscles of the corpses were unusually developed, and the green tendons under the skin were high and bulging, and they were covered with jet-black bullet marks. It had no hair on its head, it was sickly smooth, its eyes were horrible, and its mouth was full of irregular fangs, like a black hole full of crystals.

These are the living dead, who have been sleeping in shelters for many years, neither moving nor eating, just waiting quietly for their prey to come to their door.

Iron slag casually flipped the corpse and spat on it when everyone was not looking. After waiting for a while, the corpse did not move, and he gradually lost the connection with the parasitic cells in his saliva, and it seemed that the corpse of the living dead was not suitable for incubating soldier ants.

At this moment, the personnel who were investigating the front returned to the quarantine area, saying that they had found the entrance to the assembly room. Iron Slag looked at the corpse on the ground with some unwillingness, and was about to get up and leave, when a flash of inspiration suddenly flashed in his mind, and he thought of some possibility. Immediately afterward, his eyes narrowed, his back muscles suddenly exerted force, and a knotted foot immediately "whoosh" from behind, piercing into the abdomen of the corpse of the living dead.

After injecting a large number of parasitic cells into the intestines, the iron slag finally felt the throbbing of the soldier ant larvae. It didn't take long for the big red ants to emerge from the circular wound and fly up with their membranous wings.

With the help of the Scout Ant, there is no need for hunters to venture forward to investigate. After evacuating everyone to the quarantine area, Iron Slag entered the assembly room alone with the ant colony. In an instant, hundreds of scout ants swept through every corner of the room, and since the ants perceive the environment with their sense of taste, they even save on lighting.

In a matter of seconds, the iron slag is in full view of everything in the assembly room through the soldier ants. There were three living dead and one human corpse in the room, and through the sight of the soldier ants, the dead human looked to be about thirty years old, not someone he had seen, probably a member of a previous expedition. In order not to cause discomfort to others, the iron slag only allowed the soldier ants to devour the corpses of the living dead, and did not touch the corpses of humans.

Once it was safe to do so, Iron Slag called the men over and told them to stand in place, then pulled the switch down in front of the door of the operations hall.

With a long deflated sound, a crack opened in the circular metal door, and the ant colony swarmed in and flew into the action hall. This is a huge mountain space, with a size of tens of thousands of square meters. Upon entering, the ant colony scattered, surveying every corner of the hall.

"Buzz ......"

With a slight buzzing sound, a soldier ant swirled down and landed lightly on a metal platform. I saw it turn its small triangular head, and the antennae on its head swayed back and forth, sniffing the air.

Suddenly, a fierce wind came from above! As soon as it raised its head, it was "Smack!" With a bang, it was slapped into splinters of juice.

"Giggle...... A pale hand grabbed the corpse of the soldier ant on the stage, put it in its mouth, and chewed it vigorously.

At the same time, there was a slight tingling in the iron slag's mind, and the soldier's sight vanished. A few minutes later, Iron Slag commanded the ant colony to inspect the hall clearly.

In addition to a dozen or so living dead hiding in corners, there were five living dead and two broken human corpses on the ground. In the sight of the soldier ants, the death of the two humans was extremely tragic, from the shoulders to the waist was torn apart, and the ground was covered with viscous plasma and organs.

After scouting, Iron Slag took off the psionic warrior rifle, ripped off a psionic empty bullet from the cartridge belt, slowly pushed the bomb bay, then picked up the gun, accumulated psionic energy, and directed a few soldiers to gradually lead a living dead to an open space in the middle of the hall.

The living dead are slow to move, but they are incredibly powerful, and if they get close to them, they are in danger of being torn apart. Unlike him, the people who came in before were different from him, they didn't have the help of scout ants, and could only rely on the limited lighting of flashlights to explore, and if they were not careful, they would be attacked by the living dead lurking in the shadows.

As Starsand filled with bullets, Iron Slag aimed at the sleek skull and pulled the trigger.

"Bang!"

A burst of blue light shot out, piercing the skull of the living dead, spurting out from the side with a large swath of flesh. The living dead swayed from side to side before falling to the ground. The colony immediately pounced, burrowed into its head, and frantically devoured the soft tissues in its brain.

Next, Iron Slag killed seven living dead in the same way. Although his current evolution level is very high, he also feels a little tired when the eight psionic armor-piercing bullets are fired. For the follow-up action, he must maintain sufficient physical strength. He then led the living dead one by one to the assembly room and set fire to them.

"Dada...... Da Da Da ...... Da Da Da ...... Da Da Da ...... Da Da Da ...... Da Da Da ...... Dadada......"

"Ding Lingdang...... Ding Lingdang...... Ding Lingdang ......"

The dense sound of bullets and the sound of bullet casings falling to the ground were intertwined, and the living dead with sparks slowly walked forward for more than ten meters, and crawled on the ground for a few meters before he lowered his head and stopped crawling.

After cleaning up the operation hall, everyone stood by in place, and after Alva probed around, he analyzed his speculation with Iron Slag. From the current state of affairs, it appears that the previous expedition did not enter the power room, but went straight down the stairs. The power required to open the iron gate at the entrance comes from a backup power source, and when the gate is pulled down, the two chemicals inside are mixed together to produce an electric current.

The expedition's first target was definitely a warehouse in the lower middle of the Vault, and if he guessed correctly, the previous people who ventured into the lack of power might have been trapped somewhere underground. Therefore, they cannot repeat the mistakes of the past and must first find a way to start the generator set.

After listening to Alva's analysis, Iron Slag ordered everyone to find cover on their own and stay on guard, then went to the east side of the hall, pulled down the switch, and opened the door to the power room.

"Roar!"

As soon as the gate was raised, several black shadows swooped out. The iron slag standing in front of the door immediately rolled sideways continuously, avoiding the bite of several living dead people in succession. At the same time, the black pig king, who was guarding a few meters away from him, took two steps together, hugged his shoulders and collided directly.

"Bang!" With a muffled sound of metal impact, the living dead who rushed to the front were hit head-on by their huge bodies, and immediately flew out upside down, smashing over several of their kind that followed behind.

At this moment, the iron slag who was rolling to the ground had a large revolver in his hand, and I saw him pull the trigger continuously and blast towards the pile of the living dead.

"Bang!" "Bang!" "Bang!" "Bang!" "Bang!"

In an instant, the exploding bullet slammed into the steel-like skin of the living dead, bringing up a large amount of sparks, and then exploded violently.

"Stand back!" After firing five bullets, Iron Slag retreated in broken steps and shouted at the Black Pig King.

In the blink of an eye, at least ten of the living dead rushed into the hall, their mouths wide open and sticky saliva in their throats under the beam of the flashlight...... Grunt......" sound, hands facing forward, staggering slowly.

"Shoot!" After Iron Slag and the Black Pig King retreated some distance, Alva gave the order.

"Dada...... Da Da Da ...... Da Da Da ...... Da Da Da ...... Da Da Da ...... Da Da Da ...... Dadada......"

"Woooooooooo......oo Woowoo...... Woowoo woo ......"

Suddenly, the guns rang out, and bright tongues of fire erupted from the muzzles, causing sparks to erupt from the living dead in front of them.

"Dada...... Da Da Da ...... Da Da Da ...... Da Da Da ...... Da Da Da ...... Da Da Da ...... Dadada......"

After two rounds of shooting, the three living dead who walked first fell to the ground, lay on the ground and continued to crawl forward.

"Spread out."

As Alva gave the order, the crowd immediately dispersed, taking advantage of their speed and terrain to shoot in a circle around the slow-moving living dead.

"Ahh Ahh ”

Seeing that the situation was stabilizing and it would not take long for these living dead to be consumed, a scream suddenly rang out in the crowd.

The crowd quickly retreated and raised their flashlights to shine through. I saw a child-sized living dead grabbing a hunter on his back, biting him so much that blood splattered between his neck. Everyone was stunned and didn't know how to respond.

At this moment, a black shadow swept by, only a soft sound of "snort" was heard, a dazzling spark flashed, and the little living dead broke into two in the air, and fell to the ground with blood splashes.

In the next second, Iron Slag retracted his sword and sheathed it, and then stomped on the head that was screaming on the ground.
