The clouds in the sky were so low that they completely blocked out the starlight in the sky, so the night was unusually dark, and I couldn't see my fingers.

Alan relied on the infestation's gaze to follow the route provided by Sanzel towards the zombie graveyard. Along the way, the abandoned town was eerily silent, because after years of desertion, all living creatures were either used as food or infected with mutated creatures. Or even become a high-level zombie.

The bar is located in the very center of the town, and when Alan arrives cautiously, the rich almost black-red viral energy makes Allen's heart sink. The most powerful part of the infestation's vision is not its sight distance, nor its special clair-see-through ability. It is the ability to distinguish the strength of the virus, and the more powerful the virus parasite, the more intense the red color shown. So the color of the bar now makes Alan realize that what he is about to face next must be a tough battle.

Although Allen's heart was a little worried, but more excited, and only this kind of training could make him stronger, more compatible with the virus, and maybe he could also find the secret of the virus's mitochondria.

Pushing open the door of the bar, the old doorway made a screeching sound, which was particularly clear in the silence of the night.

A low sound sounded in the lobby of the bar, and Alan looked at it, and the black pressure was full of zombies lying on the ground that had long fallen asleep.

The slumber of zombies should be strictly called storing and digesting energy. Zombies only know how to hunt and eat when they wake up, and they bite and gnaw frantically, but they don't really absorb it. It is only after they return to the zombie graveyard that they have truly quieted down and fallen into a deep sleep that they will completely digest what they have absorbed throughout the day. In turn, the mitochondria of the virus that can be absorbed to promote their own evolution are transformed.

The density of zombies is too large, and Alan can only walk through the gaps between the zombies. After passing through the lobby and coming to the bar, you can see a huge crater in the floor of the bar with a diameter of about three meters, and the scarlet virus extends along the entrance of the bar into the cave.

Alan took a deep breath, and could see that the cave was not deep as far as his eyes could see, and he jumped down, the cave had already been filled with rotting flesh and blood, emitting a thick stench, which was simply torment for Allen's keen sense of smell.

"I really hate the smell!" Alan endured the discomfort in his stomach and began to explore the passageway. In addition to the rotten flesh, the walls around it were covered with large, thick, bio-vessel-like pipes. The pipes were constantly gushing, and there seemed to be some kind of liquid flowing through them. Sarcomas hung upside down on the top of the tunnel, and these sarcomas were of different sizes, ranging from the large ones to about 150 centimeters in diameter, while the small ones were only the size of a basketball.

Alan looked at these sarcomas curiously with the eyes of the infection, and he was surprised to find that these sarcomas were wrapped in strange creatures. These creatures vary in appearance, some resemble humans, others resemble canines, and some are just a churning mass of rotten flesh that keeps tumbling.

The more Alan walked, the more worried he became, this zombie graveyard was too strange. In the past, most of the zombie cemeteries were surrounded by zombies, but except for some zombies on the top, there were no living creatures here. Alan carefully avoided the sarcomas, and after walking inward for about ten minutes, it suddenly became clear that the passage had finally come to an end, and beyond that was a wider cavern. Alan cautiously crouched at the exit of the cave and looked in.

There is a slight snoring sound coming from the spacious cavern, which is closer to that of a human, unlike the dormant nervous tics of zombies. Alan looked closely, and could see a huge pool of blood at the bottom of the cave, soaked in a zombie that looked like a human, and in the line of sight of the infestation, the virus energy emitted from the zombie's body was amazingly powerful.

Its skin was pale, but it had always exuded a faint scarlet color from being soaked in a pool of blood, and its short blond hair was quite eye-catching. Its eyes were closed, its beard was short under its tall nose, and its arms were resting on the edge of a pool of blood, and it could be seen that its arms were covered with tiny scales.

"High-level zombies!"

Once an ordinary zombie evolves into a high-level zombie, it will have some special abilities, similar to the alchemy ability of humans. However, unlike humans, the virus abilities born from zombies do not require a medium, and the number and time of release are only related to the strength of the individual. So generally speaking, a transformed person of the same level cannot be compared to a high-level zombie in any way.

In addition to the ability to derive viruses from high-level zombies, the most terrifying thing is the enhancement of their own **. They will become more powerful, faster, and more agile. They also have intelligence, unlike normal zombies that only know how to flesh and kill.

What drives ordinary zombies to fight is the instinct of hunger, for the ** of flesh and blood. The high-level zombies are different, they can already control their ** very well, and at the same time, they are more picky about food.

At the top of the cavern was a huge heart-like sarcoma, beating non-stop. Thick blood vessels hung down the heart to the ground, and finally burrowed into the pool of blood, and with each beat of the heart, the pool of blood would boil for a while, and the flush on the high-level zombie's body would be a little stronger.

Alan used the infection to penetrate the huge heart, and when he saw the scene inside the heart, he only felt an uncomfortable pang in his chest, and an uncontrollable anger was about to erupt.

It turned out that the huge heart was like a biological cell, divided into separate spaces, and in each space, a still alive human was imprisoned, and the scarlet catheter burrowed into the mouths of these humans and stabbed them in the chest. Every time the giant heart beats, blood is drawn from the human body. Among the human beings, who are used as blood-making machines, there are no less than ten children, in addition to young and vigorous adult men and women.

Allen's anger was hard to suppress, but fortunately he hadn't lost his mind, Allen took a deep breath and tried to calm himself, and then he jumped lightly from the exit and landed lightly behind a huge sarcoma on the ground.

Eren pulled out the shotgun from his back, intending to blow off the huge blood vessels that connected the heart to the pool of blood. But on second thought, the humans in the heart cell are still alive, and the most important thing is that they are still not infected in order to ensure the freshness of the blood. So what if a shot passes, causing this high-level zombie to be angry and do something unfavorable to these humans?

Alan gritted his teeth and put away the shotgun, he drew his dagger, and slowly leaned on the sarcoma on the ground as a cover, moving towards the high-level zombie.

The ground under his feet is slightly soft, and people can't help but think of rotting flesh when they step on it, but Alan stopped abruptly after taking a few steps, he lowered his head, and saw that the ground under his feet was surging, and the ground he had just stepped on was sunken, and a sudden mass spread from under his feet to the blood pool, Alan didn't know what it was, but he instinctively thought that it must not be allowed to arrive, this may be the alarm system of the entire cemetery.

Alan shook his hand violently, and the dagger in his right hand shot out and nailed it to the fast-moving protrusion, and then he saw a cloud of emerald green liquid squirt out, and a fleshy worm came out. Alan raised his hand again, and the dagger in his left hand directly nailed the meat worm to the ground.

He raised his head worriedly, and saw that the high-level zombies in the blood pool did not react at all. Sure enough, just like the information that Eren knew so much about before, no matter what level of zombie they are, once they enter hibernation, it is difficult to be woken up unless a special warning system or energy is completely converted.

Alan secretly breathed a sigh of relief, he didn't dare to act rashly. He is not completely sure of defeating the opponent yet, so if he can deliver a heavy blow before the opponent is alert, it will definitely be very beneficial for the rest of the fight.

Alan began to look closely at the ground, and it took him several minutes to become clear. In order to verify his idea, Alan jumped up to the exit of the cave again, looking down from a high place, he could clearly see that around the blood pool, there were three obvious depression marks, these depression marks were covered with protrusions, Allen guessed that this was the early warning creature, once accidentally stepped on it, the meat worm would directly burrow into the blood pool to wake up the high-level zombies.

Ordinary people will definitely be tricked, because if these three circles of depressions are not carefully observed in a high place, it is difficult to find, and the ground is uneven, so it is more difficult to identify. If it weren't for Allen's extra carefulness and timely attack after hitting the trap, the high-level zombies would have already woken up at this time.

After seeing these three alarm lines clearly, Alan became more cautious, and sure enough, the alarm meat worm did not appear, and Alan also successfully approached the position of a few meters in front of the high-level zombie. Alan pulled out his shotgun, compared it and put it away. Normal guns do limited damage to high-tier zombies, and now only alchemy guns work.

Thinking of this, Alan pulled out the close-fitting Cold Moon Cold Frost from his arms!

The structure of the alchemy gun is special, there will be an alchemy circle at the handle, corresponding to the position of the palm, and the bombardment of each gun will draw the user's physical strength. Therefore, alchemy firearms can only be used by reformers, and ordinary people may be drained of their physical strength and die suddenly after a shot!

Eren raised his gun and aimed it at the head of the high-ranking zombie. He wasn't sure where the other party's weaknesses were, but in general, heads were the key to zombies, and it was impossible to blow their heads away.

"Bang!"

The moment Alan pulled the trigger, the high-level zombie opened his eyes violently, and before the bullet was close, his head was split in two, and the bullet passed directly through the middle......
