In the infrared monitor, a researcher sprang into the field of view of the lens. The defense system of the main control room reads the target image, compares the pupils and other related data in the database, and finds the biological non-base members in the lens field of view. The defense system immediately issued an attack command, so the microcomputer suspended in the main control room immediately opened fire, and the base that had been silent for several decades sounded intensive gunfire.

The fire rate of 60 rounds per minute during the fire spurt made the rain of bullets poured on the researcher's body as much as possible. The researcher only used his hands to protect the vital organs in the brain with his hands in front of his face, while the rest of the body was left to raging by bullets. The monster that was shot with meat scraps all around, but rushed forward with the firepower. When he came to the weapon platform suspended in the sky, the body jumped up high, grabbed the machine gun with both hands and suddenly pulled it, and suddenly pulled the machine gun off.

When the body jumped to the ground, his body was already riddled with holes. But the researcher didn't care at all, and at this time, the other two nearby weapon platforms also started firing, gunshots and firelights appeared from time to time in the base, and the still actionable microcomputer faithfully performed the defense procedures. Although judging from the fact that there are few casualties, such an attack is not enough in strength.

In the control room, Ling glanced at the cameras of several monitors, and no longer paid attention to the situation outside. Although the threat of microcomputers to spawns is limited, the armored outer wall of the control room cannot be broken through by spawns that have not yet evolved their attack weapons. Compared with the derivation, Zero is more focused on the task at hand. He was busy operating in front of the podium, moving his zero hands on the virtual light screen, decomposing and comparing several three-dimensional topographic maps from the main computer, and using the computer as the assistance to find out the biochemical zone. Where and the shortest route of advancement.

Admiral Iger’s video mentions that Dr. Curd, parasitized by the Z substance, has a fatal flaw. Now that he has to leave the base, conflicts with Curd are inevitable. The main computer has shown that all known external passages have been closed, and now only the working passage in the purification unit is left. But there must be Kode's trap. To leave the base, there seemed to be no other way except to kill the humanoid monster parasitized by the Z material.

According to the information provided by Admiral Iger, Z matter has the instinct of infinite division and evolution. It can be said that Cod, who was parasitized by him, has become a terrible monster. Judging from the continuous emergence of spawns and their evolution through battles with Zero in a short period of time, the longer the battle with them drags on, the more disadvantaged it is for Zero.

Under such circumstances, Zero needs to know where the defects of Z matter are, in order to be able to kill with one blow.

Soon, the computer has planned the shortest route to the biochemical experiment area. Judging from the distance of the route, if you advance at full speed at zero, it only takes 5 minutes to arrive. But he looked at Beyonce and had to recalculate the time of arrival in his heart.

Beyonce seemed to sense Zero's gaze. She turned around, and she saw that the beautiful Patriarch had collected the weapons left by the guards in the control room at some point, and almost armed herself as a small soldier who charged forward.

With a glance, Beyonce's side besides four or five automatic rifles, two microcomputers, several ammunition boxes, and more than 20 fragmentation grenades. There is also a rocket launcher and five shells.

Beyonce smiled to Ling: "Just do what you are going to do, I will stay here. Let’s not say whether those things can come in. Even if they can, if there are these good things, I will let them know the truth. Miss is amazing!"

She wiped her nose, her face stubborn.

Zero knew that Beyonce didn't want to be her burden, but it might be a good idea for her to stay in the control room. This is the safest place in the base, almost like a fortress. It is impossible to enter with bare hands only with those fifth and sixth-order spawns. Beyonce staying in the control room is definitely safer than staying with Zero. After all, the place Zero is going to may be Cod's lair.

"Alright, I will come back as soon as possible. Trust me, I won't leave you behind." Ling said with a soft kiss on Beyonce's forehead.

Beyonce tried her best to hug Zero, and said: "You are mine, Zero. So, I don't allow you to have anything, you have to come back alive to see me!"

"Yes, sir." Ling smiled.

Beyonce let go of him, pushed a little and said, "Go, don't worry about me."

Nodding their heads, the two walked out of the control room and came outside the exit where the body of Admiral Iger was located. Zero commanded: "As soon as I rush out, I will attract the attention of those monsters. Don't worry about anything, as long as I leave, you will immediately close the door."

"I see."

After all the preparations are made, Zero presses the opening button of the gate. Immediately, the armored gate on the inner side rose upward first, while the outer gate slowly opened. The time the door was opened attracted the attention of nearby spawns. Before they could react, Zero flew out at high speed with patches of afterimages. In order to attract the attention of the spawn, he didn't use shadow jumping, only rushed at full speed, and at the same time materialized two submachine guns in his hands. Zero shot while running, and the line of fire that shuttled through the darkness immediately attracted the spawn.

They only jumped off the outer wall of the central control room, screaming and chasing after Zero.

At the moment when Zero left, Beyonce took a leap, rushed from behind the cover to the door, and patted the closed button again. In this way, she watched the door opened and closed, and quickly cut Zero from her sight.

When only Beyonce was left in the central control room, she turned to look at the body of Admiral Iger and shook her head with a smile. Beyonce dragged the admiral's body aside, and then dragged tables and chairs from the control room to form a simple cover. There is a 100-meter-long passage between the gate and the control room. This passage will become the focus of Beyonce's defense.

In this short one-hundred-meter passage, she arranged three checkpoint-like shelters. If the entry from outside the gate is not zero, then Beyonce will use these checkpoints to pour fierce firepower on other things. In addition, she also found some slender steel wires, combined them with fragmentation grenades, and some simple traps that restricted the passage of infantry.

As she herself said, Beyonce used all the knowledge she learned to create a favorable environment to protect her safety. She is not a woman who needs to rely on a man to survive. She has been destined to become a warrior since her mother took over as the head of the house. Whether in the business field or on the real battlefield!

The sound of gunshots echoed in the passage of the base, and when it disappeared, the last spawn chasing Zero fell to the ground weakly. There were bullet holes all over his forehead, and the rapid blow of the submachine gun almost smashed the face of the body. More importantly, the bullet destroyed that important organ in his brain, so that this dangerous killing tool had to stop operating.

Zero's expression is not happy at all.

The basic abilities of this batch of spawns have been improved, so that every time Ling kills a spawn, he has to pay more strength and spirit. These things don't seem obvious, but when the number accumulates to a certain extent, it becomes a terrible disadvantage. Kod doesn't need to take action personally. He just needs to continuously send out spawns, and the tactics of the sea of ​​people alone are enough to drag him to death.

This makes Zero more determined to find out the flaws in the z material, otherwise, it doesn't matter if this battle is not fought.

Five minutes passed in a blink of an eye, and the biochemical experiment area was already in sight.

It's surprisingly quiet here.

Zero could not feel any traces of the spawning activity, he thought about it, and materialized a few remote-controlled bombs, and installed them in the hidden part of the passage for emergency needs. After doing this, Zero only entered the biochemical experiment area. Pass a door that has stopped working, and walk through a silent disinfection passage. However, Zero, who was mentally prepared for everything, couldn't help being stunned when he actually walked into the experimental area.

He had imagined any situation, but never thought that the experimental area is still in operation!

Zero almost doubted his eyes. In front of him, the squarely arranged cultivation tanks were emitting aquamarine fluorescence. That is because the lighting in the culture tank emits light through the nutrient substrate, and in these faint green lights, there is still a naked human body floating.

These people include men and women, and even a few old people and children in them. Without exception, these people have a special biological organ attached to their chests. It looked like a lanky spider, with eight tentacles protruding from the periphery of the rib-like organ, and plunged deep into the human body. The reason why it looks like an organ is because it stretches and shrinks to a degree, just like a peripheral heart.

Zero carefully inspected the cultivation tank and found that the data on the screen below the cultivation tank showed that the people in it had normal life reactions. What is strange is that they seem to fall into a deep sleep, and they should be awakened by something that has suppressed their will. Zero again looked at the biological organs in these people's chests, thinking that it should be related to this strange thing.

At this moment, a deep and hoarse voice sounded: "What do you think of my'food'? Powerful invaders, don't doubt, they are all living people."

Looking at the source of the sound, there are only countless training slots arranged in square in his eyes. He quickly swept into the training trough square, and a faint figure disappeared in the distance. Then, the voice came from elsewhere: "In addition to most of these exhibits are the researchers before the base, there are also a small number of wild people in villages and towns near the surface. How are you excited to hear this news? Yes, there is indeed a channel to the outside world in this base. Do you want to know where it is?"

"Is there a working channel in the water purification unit area? Dr. Cod!" Zero stood still and said coldly.

The voice sounded from the direction behind Zero again: "It seems that Iger left quite a lot of information, so let me guess again, are you here to find the research materials of the old Karahan? Okay, I Acknowledge that there are defects in such things as substance z. However, do you think I will allow the materials that record the defects to exist to this day?"

Dr. Cord's voice came erratic from all directions, making it impossible for Zero to capture his position at all. As Iger said, Cod is not only cruel, but also cunning.

"That really surprised me. It seems that the parasitism of substance z has not completely turned you into a mad dog." Zero sarcastically said.

In an instant, a killing machine came from the direction on the left. Zero turned around, but as soon as he raised the gun, the murderous intention had disappeared.

"I have to say, you are such a dangerous guy. You don't have to try to irritate me. I can sell it like this and definitely do better than you. Rather than try to irritate me, it's better to worry about your situation. Invader. You are so powerful, so powerful that it makes my heart beat. My kingdom has not had food of your quality for a long time. So don't worry, I won't kill you right away." Ke De blame laughed: "I will keep you awake, but tear off your skin and your flesh little by little. I will taste you slowly and fully absorb your powerful genes to correct certain defects in substance Z. I believe, wait After completely absorbing you, I will evolve into a perfect creature!"

"Thank you for looking up to it, should I feel honored?" Ling sneered.

Kede laughed and said, "Of course, it is your glory to be part of my genes, intruder."

"It seems that you stayed in the base for too long, and you have become a sloppy old man for a long time."

"Perhaps it is. After all, in the last twenty years, you and that woman are my first visitors. To show my respect, I will prepare the highest standard death feast for you." Cod whispered quietly. .

Zero was silent, and he lowered his head. Liu Hai blocked his eyes, and the fluorescent light of the cultivation trough shone on Ling's face, but it clearly made Cod, who was hiding in a corner, to see the smile gradually drawn on Ling's face.

There are many meanings in this smile, at least Cod can read the contempt and self-confidence.

Contempt for Kode, and self-confidence.

"What are you laughing at!" Kede asked angrily, while keeping moving.

Ling said indifferently: "It's nothing, but I haven't seen anyone as stupid as you. Dr. Cod, substance z gives you a terrifying gene, but it doesn't seem to improve your wisdom. Otherwise, why would you tell yourself? I have a material defect~lightnovelpub.net~ even if it's just one of them."

"What?" Curd was taken aback, and said: "When did I tell you?"

"Have you not noticed yet?" Ling looked at the humans in the training tank: "You said that some of these people came from the surface, and you pointed out that Bess and I were the first visitors to the base in the past two decades. In other words, you stayed for a long time. In the base. Although you can go to the surface, you only bring back the refugees from nearby villages and towns, which means that your radius of activity is limited."

"I'm very curious, what is the reason for such a powerful creature like you to make you nostalgic for this tomb-like underground base?" Ling said with a faint smile: "The answer is naturally not something like nostalgia, but you can't leave. . So what makes you unable to leave? Or, is there anything on the surface that matter z fears? Radiation?"

"No, the surface radiation is something after the cataclysm. The z-substance produced in the old age, Dr. Karahan should not have envisioned the environment of the new age. Therefore, it should be something more ancient, and it is something that existed in the old age. . Then I guess, could it be sunlight? Or ultraviolet rays in sunlight?"

Suddenly, Zero felt that Dr. Cord, who was constantly moving, stopped for a moment. Suddenly, he knew that he had found one of the weaknesses of the z-substance!
