The passage from the first floor of the underground base to the second floor is a ramp, and when Xu Mo was waiting for Caesar at the exit of the ramp just now, he had already seen scattered human corpses. However, the deeper you go into the core of the second layer, the more corpses you will find along the way.

The first floor of the underground base is a neatly planned research base, with dormitories, research institutes, warehouses, and vaults, all of which are well distributed. However, the second level is different, and from the ramp passage down, there is a circular corridor that spirals inward.

There are some dim voice-activated lights above and on the walls on both sides of the corridor, but most of the bulbs are damaged, and the entire circular corridor is bright and dark, which is particularly eerie. Compared to the good ventilation and temperature control of the first floor, the second floor is cold, damp and lifeless, and is more of an underground air defense tunnel than a research base.

On both sides of the corridor are basically small rooms, the doors of these rooms are basically heavy iron doors, and there is a palm-sized square viewing hole above the iron door, as if all these rooms are cells. Most of these cells now have iron doors ajar, and there are many humanoid corpses lying outside the doors and in the corridors.

After going deeper, the two slowly slowed down. Xu Mo squatted down and turned over a corpse sitting against the cell door, which was a young man. He was no more than eighteen or nineteen years old, wearing a blue-gray sleeveless prison uniform, with a strong body, muscular limbs, and vigorous hair on the surface.

His fatal wound was in the neck, half of his entire neck was broken, and signs of decay had begun to appear. Judging from the fractured surface of the wound, even Xu Mo, a layman, could see that he was bitten to death by some kind of creature.

Xu Mo stood up, pushed open the cell door behind him, and walked into the cell. The cells were empty on all sides, with no furnishings, except for a narrow barred air window on one wall. In one corner of the cell, there is a squatting urinal connected to the sewer, and there are several rusty shackles on the wall, and the position of the shackles should be buckled on the limbs, waist and neck.

There were dark red blood stains on the floor of the cell and on the rusty shackles. The color of the blood stains varied, some were purple and black, some were dark red, and some were bright red, and it seemed that many people had been imprisoned in this cell. There was a rancid smell throughout the cell, mixed with the urinal in the corner, which made people feel nauseous and vomiting involuntarily.

"Cole, what do you say is going on here? Why haven't we seen a single werewolf yet? What about Lucian? What about those high-level werewolves? Didn't Lucian cooperate with humans? But in the research base on the first floor, I did see a lot of werewolf guards and werewolf assistants? Caesar scratched at his hair in annoyance.

"Lucian and they have cooperation with humans, there is no doubt about that. And I believe that the second layer of the underground base is controlled by the werewolves, and if the second layer is controlled by humans, even if it is a prisoner, they will replace those broken light bulbs and install good ventilation and temperature control facilities. Only werewolves who have night vision and like cold environments will let this place become like this! Xu Mo calmly analyzed.

"I don't think Lucian and the high-ranking werewolves are here right now, they should be doing some big operation, or they were transferred out of here by the Holy See and the Exorcists. It's just that I can't figure it out, the foreign enemy should have invaded from the first layer, why did the damage suffered by the second layer be more serious than the first layer? ”

"Hehe, I know this!" Caesar grinned and laughed dryly, "When I first came down, there was a big commotion going on here. The prisoners here don't know when there was a big riot~ when there was a big riot, and many of the prisoners rushed out of the cells and clashed with the humans who had retreated to the second floor, as well as the werewolf guards. ”

"Are you sure you didn't let them out!" Xu Mo asked expressionlessly.

"I swear, I didn't do it!" Caesar hurriedly raised a paw and swore that he would come.

"I believe in you!" Xu Mo sighed, "Look at this young man, his neck was bitten like this, and there wasn't much blood on the ground. And the muscles all over the body are pale, obviously because of excessive blood loss, which is done by vampires or vampire zombies. ”

"Vampire zombies? What is it? Caesar was stunned, he had never heard of such a creature.

Xu Mo was also a little surprised, Caesar didn't know about the existence of vampire zombies, and after thinking about it, he asked, "Caesar, did you hear of a drug called LOL when you were running a bar and a fight club?" ”

"LOL drugs, no. However, recently there is a drug called Heaven's Gate on the market, after ordinary humans take it, not only will they get extreme pleasure, but also strangely, their physical fitness will also be enhanced a lot in a short period of time, almost comparable to some werewolves and blood descendants with thin physiques! Caesar shrugged his shoulders and said strangely, "It's just ......."

"It's just that they gradually lose their minds, become irritable, and have a fickle temperament, don't they? And this drug doesn't have any effect on you werewolves, right? Xu Mo sighed.

"How do you know? I also find it strange that we werewolves also have half of the genes of humans, and a lot of drugs are also effective for us, so it stands to reason that this kind of gate to heaven should be effective for us as well. I once tried to smoke a little, but I didn't feel it at all, originally I thought that my strength was too strong, and I was immune to drugs, but some new werewolf descendants don't seem to be interested in this kind of thing! Caesar said a little strangely.

"Of course, Heaven's Gate should be a derivative of LOL, and you werewolves are immune to this drug. Because the main ingredient of this drug is the ashes of vampire zombies, which are humans who have been injected with blood genes. Xu Mo said with a serious face.

"Directly injected with blood genes? Didn't those humans go through the process of first embrace? Caesar's eyes widened and he said incredulously, "This is complete murder for you humans. They will become bloodsuckers with no intelligence...... Oh, I see what a vampire zombie is! ”

"Caesar, as an undead creature, do you think it is possible for these humans, who have become vampire zombies, to regain their sanity?" Xu Mo asked tentatively.

"It's impossible, it's an irreversible process of change. Humans can become members of the undead after experiencing the first embrace, but no matter how much the Bloods and Werewolves change, they cannot become humans. If the rice is eaten by someone, it will turn into stool, and if you eat the stool again, can you pull out the rice? Caesar said with a wry smile.

"Dead boy, can't you just change the analogy?" Xu Mo said with a smile.

"Cole, why are you going to explain vampire zombies to me? Could it be that you think this place ......" Caesar frowned and said uncertainly, "Why did Lucian do this, and that LOL didn't do anything to us werewolves?" ”

"Alas, Caesar, you have spent hundreds of years in human society, and you still don't know anything about human beings? It's not Lucian going to do it, it's the humans themselves! I think that's the price Lucian pays, he helps humanity do all this dirty thing, and humanity repays him with technology! Xu Mo said calmly.

"I ...... After returning to this world, at a human research institute, I saw these blood-sucking zombies that were used as experimental objects. At that time, I liberated the prisoners in the laboratory, and the blood genes injected by those prisoners came from Nirena and Serena. Within half an hour of the two of them waking up, several werewolves rushed to capture them. Coupled with the situation here, I am even more certain that Lucian and humans are working together to make this LOL drug. ”

"What are we going to do?" Caesar put away the cynical expression on his face and asked cautiously.

"It's not us, it's what you're going to do, Caesar!" A smile appeared on Xu Mo.

"After the spread of these drugs...... Humans are playing with fire**! Caesar said solemnly, and then the serious expression on his face fell, and he said with a wry smile, "Cole, I don't want to lie to you, I'm not willing to help humans, aren't you disappointed!" ”

"No, Caesar, what I told you when I liberated you will not change now. Werewolves are natural to prey on humans and bloods, just as humans feed on other creatures, there is no right or wrong. You are not human, and you don't have to hold yourself to the moral standards of human beings! Xu Mo said quietly.

"That'...... What about you? Caesar was silent for a moment, then looked up and asked.

"Me? Haha, I don't know yet, I haven't found this world yet, and I have to do something. Let's see, Caesar, let's see. Xu Mo raised his head and laughed, but his eyes were cold.

After a brief conversation, the two fell silent again and continued to walk towards the core of the underground base. After a while, they finally saw the exit of the circular corridor, the spiral inward corridor, and its exit was also the core area of the underground base.

The exit faces a duplex hall, which is almost the size of a football field and nearly twenty meters high, with numerous incandescent lights inlaid at the top, making the whole hall as bright as day.

In the middle of the hall there are three tube elevators, which are connected to the top of the hall, and at first glance, it is clear that the top of the hall is not the end of them, and it seems that these three elevators lead directly to the ground. It is no wonder that the researchers of the first layer will retreat to the second layer after being invaded by foreign enemies, and it turns out that there is the most direct and safe retreat route here.

At the top of the elevator, there is a helicopter or something convenient means of transportation, so that they can escape the pursuit of foreign enemies. However, at this time, this originally safest retreat route was greatly threatened.

The reason is that there are many vampire zombies around the central elevator in the hall, most of these vampire zombies have lost their minds, and they have been attracted by the retreating researchers on the first floor from the cell corridor, which is why Xu Mo and the others did not meet them in the corridor.

On the periphery of the three elevators are a few werewolf guards, although the strength of these werewolves is much stronger than that of vampire zombies, but two fists are invincible to four hands, and they can only protect themselves at most, and there is really no way to stop all the vampire zombies. Every now and then, behind them, the crowd waiting for the elevator would hear screams, the result of the Vampire Zombies breaking through the perimeter defenses and dragging the researchers out of the defensive circle.

These researchers, who are dragged into the zombie horde, will be immediately killed by the humans in the inner layer with pistols. Rather than being eaten alive by vampire zombies, using bullets to make them die quickly is a benevolent act.

"Whew!" Several vampire zombies twitched their noses, turned around, opened their mouths wide, and pounced on Caesar. Even the invisible Xu Mo could not escape the sensitive sense of smell of the vampire zombies, and was attacked by them at the same time.

"Huh!" Xu Mo's eyes suddenly flashed, among these blood-sucking zombies, he actually found an acquaintance, "Caesar, don't kill it!" ”
