Half an hour later, everyone unloaded their luggage and packed their equipment. After leaving the two of them to guard the camp, they arrived at the entrance of the underground shelter. The reason why Tie Zha dared to use the lightning hammer to recruit them was partly because the situation was urgent. Even though he and the Black Pig King were powerful, they were still weak and difficult to save. On the other hand, because these people were all subordinates of Blood Eagle, he believed that the followers of an Earth Walker would not be those without faith. In other words, if these people were cowards, he wouldn’t dare to reveal his lightning hammer.

Looking at the dark mountain tunnel, Alvar, who had explored it twice, brought a wooden box, took out paper and pens, drew a sketch on the spot, and explained to Tie Zha the general structure of the underground shelter. In most cases, the design of the shelter was similar. Although there were special structures, they were still a small number.

After entering the tunnel, the first area is usually the isolation area, followed by the assembly room. The main function of the quarantine zone is to inspect and disinfect to prevent the entrants from carrying viruses or other harmful substances; The function of the assembly room was to wear radiation-proof clothing, tidy up equipment, and inspect the location of weapons.

The assembly room used to be the operation hall. Its main function was to gather personnel, handle formalities, assign tasks, and a series of other matters. The action hall is usually connected to elevators, generator rooms and air filtration centers. Among them, the power generation room was the core of the underground shelter. Without electricity, the entire shelter would be paralyzed. Generator units are generally located in shallow soil for maintenance and moisture protection.

Below the first floor, there was usually a series of living facilities, such as an activity room, a living room, a dining room, a medical cabin, and a material warehouse. Further down was the factory area. There were water purification centers, food processing centers, pharmaceutical manufacturing centers, and so on.

Normally, exploration teams would have priority access to the generator room and try to start the generator unit. If electricity is available, lighting and ventilation systems can be turned on to reduce the difficulty of exploration.

The route of the operation was therefore through the tunnel into the quarantine area, into the assembly room, 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 living dead were extremely powerful, and their body tissues were exceptionally tough. They were close to steel bodies, so the damage that gunpowder bullets could do to them was very limited. The weakest of the living dead also had the strength of a Golden Beginner, but their movements were slower and their eyesight was poorer. Only their hearing was considered good. As long as they didn’t get close, they wouldn’t be alarmed if they didn’t make a sound, so many people would choose to bypass them in the process of exploring.

However, since the objective of this operation was to rescue, not to explore, it would be best to clear out the living dead along the way, so as to avoid complications during the retreat.

Alva’s suggestion was approved by Tie Zha. After discussing it, everyone set off.

A few seconds later, several beams of light shot out from the flashlight and swept back and forth in the tunnel, illuminating the dark space. It was a straight tunnel with alloy steel plates embedded with willow nails on the top and sides of its head and a hollow iron mesh beneath its feet. Looking along the road, this place was quite intact, and there were almost no traces of rust.

After walking for about a thousand meters, everyone arrived at a large circular metal door. At this moment, the door had already been opened. With the light from the flashlight, one could see that there was a large cylindrical space inside. After observing at the door for a while, the two agile insecticides carefully walked in. After checking to make sure that there was no danger, they called everyone in.

There were two pale-skinned human-shaped corpses lying on the ground. Looking closely, the muscles of the corpses were exceptionally well developed. The veins beneath the corpses were tall and bulging, and there were black bullet marks all over the corpses. There was not a hair on its head, showing a morbid smoothness. Its eyes were deeply sunk into the bone fossa, making it look extremely terrifying. Its mouth was filled with irregular fangs, like a black hole filled with crystals.

These were the living dead. They slept in the sanctuary all year round, neither moving nor eating. They quietly waited for their prey to come to their door.

Tie Zha casually flipped through the corpse and spat out saliva while the crowd was not paying attention. After waiting for a while, the corpse did not move at all, and he gradually lost contact with the parasitic cells in his saliva. It seemed that the corpse of a living dead person was not suitable for incubating a soldier ant.

At this moment, the investigators at the front returned to the quarantine area and said that they had found the entrance to the assembly room. Tie Zha looked at the corpse on the ground with some unwillingness. Just as he was about to get up and leave, a thought flashed through his mind and he thought of a possibility. Shortly after, his eyes narrowed, and his back muscles suddenly exerted strength. A knot of foot immediately jumped out from behind and pierced into the abdomen of the corpse of the living dead.

After injecting a large number of parasitic cells into his intestines, Tie Zha finally felt the throbbing of the ant larvae. Not long after, large red ants emerged from the circular wounds and flew up with their membrane wings.

With the help of the scouting ants, there was no need for the hunters to venture forward to investigate. After evacuating everyone to the isolation zone, Tie Zha brought the ant colony into the assembly room alone. In an instant, hundreds of scouting ants swept across every corner of the room. Because the ants sensed their surroundings with their sense of taste, they didn’t even need to illuminate the surroundings.

Within seconds, Tie Zha could see everything in the assembly room through the ants. There were three living dead people and a human corpse inside. Through the sight of the ants, the dead human looked to be around thirty years old. He was not someone he had seen before, but a member of the previous expedition. In order not to cause any discomfort to the others, Tie Zha had only allowed the soldiers to devour the corpses of the living dead, not the corpses of humans.

After confirming that it was safe, Tie Zha called the people over and told them to stay on guard. Then, he pulled the switch in front of the operation hall.

Along with a long sound of deflation, a crack appeared in the circular metal door. Ants immediately swarmed in and flew into the action hall. This was a huge mountain space, ten thousand square meters in size. After entering, the army of ants scattered in all directions, searching every corner of the hall.

“Buzz …”

With a faint buzzing sound, an ant circled down and lightly landed on a metal platform. It turned its small triangular head, its antennae swinging about, sniffing at the smell of the air.

Suddenly, a fierce wind came from above! Just as it raised its head, it was “pa!” With a loud sound, it was smashed into pieces that splashed with juice.

A pale hand grabbed the corpse of the soldier on the stage, put it into its mouth, and chewed hard.

At the same time, a slight stab of pain came to Tie Zha’s mind, and the soldier ant’s line of sight disappeared. A few minutes later, Iron Slag commanded the ant colony to investigate the hall thoroughly.

Apart from a dozen living dead hiding in the corner, there were five living dead and two shattered human corpses on the ground. In the eyes of the soldiers, the deaths of the two humans were extremely tragic. They were forcefully torn apart from their shoulders to their waist, and the ground was covered with viscous blood and organs.

After reconnaissance, Tie Zha took off his psionic warrior rifle, pulled an empty psionic bullet from the cartridge belt, and slowly pushed it into the cartridge cabin. Then, he picked up his gun, accumulated psionic energy, and commanded a few soldiers to gradually lead a living dead person to the empty space in the middle of the hall.

The movement of the living dead was extremely slow, but their strength was incomparably great. Once they got close, they would face the danger of being torn apart. Previously, these people who came in were different from him. They did not have the help of scouting ants, so they could only rely on the limited lighting of the flashlight to explore. If they were a little careless, they would be ambushed by the living dead who were hiding in the shadows.

When Xingsha was filled with bullets, Tie Zha aimed at the smooth skull and pulled the trigger.

“Bang!”

A ray of blue light shot out, piercing through the skull of the living dead and spraying out from the side with large amounts of flesh and blood. The living dead man shook left and right, then fell to the ground. The colony immediately flew forward and drilled into its head, crazily devouring the soft tissue in its brain.

Next, Tie Zha used the same method to kill seven living dead. Although his current evolution was very high, he felt a little tired when eight psionic bullets shot out. In order to follow up, he must keep up his strength. Afterwards, he led the living dead to the assembly room one by one, allowing everyone to concentrate on shooting.

“Dada … Dada … Dada … Dada … Dada … Dada … Dada … Dada … Dada … Dada …”

“Ding … Ding … Ding … Ding … Ding … Ding …”

The sound of bullets and the sound of cartridges falling onto the ground interweaved. The living dead, covered in sparks, slowly advanced for more than ten meters, and then crawled on the ground for a few meters. Only then did they hang their heads and stop crawling.

After cleaning up the operation hall, everyone stood on standby. After Alva looked around, he analyzed his conjecture with Tie Zha. Judging from the current situation, the previous expedition team did not enter the power generation room, but directly went down the stairs. The power required to open the iron door at the entrance comes from a backup source, and when the lever is pulled down, the two chemicals inside mix together to produce an electric current.

The exploration team’s primary target was definitely the warehouse in the middle and lower floors of the sanctuary. If he was not wrong, the people from before had ventured into the warehouse without electricity and might have been trapped somewhere underground. Therefore, they can not repeat the same mistakes, must think of a way to start the generator set.

After listening to Alva’s analysis, Tie Zha ordered everyone to find shelter on their own and stay on guard. Afterwards, they arrived at the east side of the hall and pulled the switch to open the door of the power room.

“Roar!”

Just as the gate rose, a few black shadows pounced out. Standing in front of the door, Tie Zha immediately rolled sideways, avoiding the bite of a few living dead people. At the same time, Black Pig King Three, who was standing a few meters away from him, took two steps at the same time and directly crashed into him with his shoulder in his arms.

“Kuang!” With a muffled sound of a metal collision, the living dead rushing at the front were knocked head-on by their enormous bodies. They immediately flew backwards, knocking over several of their fellow creatures behind them.

At this moment, Tie Zha, who was rolling on the ground, had a large revolver in his hand. He continuously pulled the trigger and threw it towards the pile of living dead.

“Bang!” “Bang!” “Bang!” “Bang!” “Bang!”

In the blink of an eye, the explosive bullet smashed into the skin of the living dead like steel, causing a large amount of sparks to burst out at the same time.

“Retreat!” After firing five bullets, Tie Zha shouted at the Black Pig King as he retreated.

In the blink of an eye, at least ten living dead people rushed into the hall. Under the illumination of the flashlight, their mouths were wide open with sinister expressions, leaving behind sticky saliva. There was a “Gulu … Gulu …” sound coming from their throats. Their hands moved forward and they staggered forward slowly.

“Shoot!” After Tie Zha and the Black Pig King retreated for a while, Alva gave the order.

“Dada … Dada … Dada … Dada … Dada … Dada … Dada … Dada … Dada … Dada …”

“Wuwu … Wuwu … Wuwu … Wuwu …”

In an instant, gunshots rang out in all directions, and bright tongues of fire spat out from the muzzle, causing sparks to appear all over the living dead in front of them.

“Dada … Dada … Dada … Dada … Dada … Dada … Dada … Dada … Dada … Dada …”

After two rounds of shooting, the three living dead people at the front fell to the ground, lying on the ground and continuing to crawl forward.

“Spread out.”

With Alva’s order, everyone immediately dispersed, using their speed and terrain to circle around the slow-moving living dead.

“Ah! Ah!”

Seeing that the situation had stabilized and it wouldn’t be long before the living dead were exhausted, a miserable scream suddenly sounded from the crowd.

Everyone quickly retreated to the surroundings and lifted their flashlights to shine. A child-sized living dead man was grabbing onto the back of a hunter, biting him until blood splattered all over his neck. Everyone was stunned and didn’t know how to deal with it.

Right at this moment, a black shadow swept past, and there was a soft “chi” sound. A dazzling spark flashed past, and the little living dead man broke into two pieces in the air and fell to the ground with blood sprayed on his face.

The next second, Tie Zha sheathed his sword and crushed the head that was howling on the ground.
