The three of Chu Yu left, leaving the city of the birdmen, and went deep into the fourth layer of the underground.

smashed people's pots, kicked people's load-bearing walls, destroyed a few houses by the way, and made the city in the sky become... Landing on the ground in the sky city, the "visit" of the three of Chu Yu can be described as a continuous disaster.

Even so, the three of Chu Yu left safely.

The birdman is not a birdman at all, he is very reasonable, if he changed someone else's words, he would have been desperate with Chu Yu and the three of them a long time ago, but the birdman not only let them go, but also provided a lot of information.

In return, Chu Yu gave the Birdman tribe a piece of roast chicken cub beast dry.

The entire underground world, whether it is the area of the area, the number of people, and the degree of civilization, is constantly increasing, and it is multiplying geometrically.

There was no need for Chu Yu to continue to explore the fourth layer, because except for the birdman, there was not a single hair left in the other intelligent races, and all of them were slaughtered by the deformed monsters, and they were in a state of dust returning to dust and waiting for resurrection in other oblivion pits.

The ice field area that the old patriarch and little Winnie mentioned before was even more deserted, except for the deformed monsters that were deformed monsters.

Freaks are very resilient, they can survive in extreme environments, and they don't eat or drink, and they don't have anything to do but find someone to fight and tear them up, and the birdmen are also the only intelligent race in the fourth layer of the entire underground that survives in the human world.

The "Fork Mystery" that has been plaguing Chu Yu, the female leader Lilith also gave an answer.

This fork is indeed an energy weapon, an energy storage energy weapon, but it was not developed by this generation of birdmen, but was researched when they were more than ten generations, that is, when the birdman civilization was at its most prosperous, and the technology of using molecular rearrangement and combination is also the only weapon left.

The birdmen have also been developed, with a population of more than 70,000 at its peak, and the title of guardian is well deserved, not only guarding themselves, but also guarding the entire fourth layer of the underground, and then guarding and guarding other races will be wiped out.

The fork's scientific name is the Guardian's Spear, and it is also an exclusive weapon for male Guardians.

The flame snake originally wanted to get one over to play around, but unfortunately, the birdman could use it, but he couldn't.

Because there is a film on the palms of the birds, and this film can play the role of insulation, but the snake does not have this function, the fork can come over, but the snake can't use it, because if it is used, the snake has to blow the lamp and pull out the wax and be electrocuted into coke.

The birds were very righteous, not only informing Chu Yu of the information they wanted to know, but also providing vehicles, flying vehicles, and human flying vehicles.

The birdmen all had wings, and the six male birdmen, two in a group, and one in a group, took the three of Chu Yu across the mountains and the sea, and also took the three of them through the Monster Mountain and the Monster Sea, flying in a straight line for nearly twelve hours, and finally sent them to the entrance of the ladder on the lower level.

During the flight, Chu Yu realized that there were so many deformed monsters, except for the area of the birdman, the other areas were almost all deformed monsters.

After waving goodbye to the six friendly male birdmen, the three of Chu Yu entered the ladder lifting platform.

Entering the lifting platform this time, Chu Yu wanted to figure out one thing.

After entering the lifting platform, Chu Yu said to the flame snake and Dracula: "Every time I entered the underground world from the lifting platform before, I always felt that my spirit was suddenly in a trance, this situation lasted for a short time, less than a second, and it seemed to have the power to tear me apart, but this process was too short, I don't know if it was an illusion or what's going on, especially like the feeling of entering the space-time channel, when you reach the fifth layer for a while, you pay attention to it and see if there is anything abnormal." ”

Firesnake and Dracula nodded.

Chu Yu had also mentioned this matter before, Dracula didn't feel anything, maybe he had, but he didn't pay much attention to it, of course, it may not be, after all, this guy is different from others.

The Yan Snake had the same feelings as Chu Yu, but as Chu Yu said, the time for this situation was too short, and the Yan Snake didn't take it seriously at that time.

Knowing that the time for the ladder platform to descend would last for a long time, Chu Yu adjusted his speed and fell asleep with his tactical bag on his pillow.

He had a feeling that perhaps as he went deeper into the underworld, he would bring more confusion, but he was getting closer to the truth.

Chu Yu fell asleep, and Dracula also yawned and lay on the platform, faster than Chu Yu fell asleep, and as soon as he lay down, there was a slight snoring sound.

"You sleep and put your shoes on. ”

Dracula flipped and went back to sleep.

The flame snake glanced sideways at Dracula, and was secretly strange in his heart.

With the arrival of the underworld, Dracula seems to sleep more and more, and he sleeps when he has the opportunity, he can sleep better than Chu Yu, and he can't wake up when he is awake.

You must know that this situation is very abnormal, when he used to toss in the surface world, Dracula basically rarely sleeps, only a few hours a month, when others are awake, he also tosses blindly, and when others sleep, he continues to toss blindly, and has never seen a time to yawn.

But after coming to the underworld, Dracula was already extremely depressed compared to his previous state, and he yawned after a few moves.

Chu Yu was actually the first to notice this situation, but like the Flame Snake, he couldn't figure out what was going on, and Dracula himself didn't understand why this situation happened.

There are more than one anomalies on Dracula, and the speed of recovery from injuries is definitely faster than in the surface world, and even large wounds will heal in a visible way.

In the past, when he was on the surface, Dracula had to spray some Yunnan Baiyao to bandage the wound, but now he can just put a band-aid on it, and it will be fine in a while.

The ladder lift descended for about ten hours before finally reaching the fifth floor.

The three of them looked at the fifth layer of the world outside the transparent cover, and their movements were uniform, first rubbing their eyes, and then scolding.

Chu Yu: "!"

Flame Snake: "What the hell is this?"

Dracula: "It's over!"

The three of them were cautious and fluttering, and they all came to their throats, and they still remembered what it felt like to enter the lifting platform.

The trio now wish that the platform would never fall to the ground.

Because it's a battlefield outside!

On one side is a deformed monster all over the sky, and on the other side is a torrent of steel composed of mecha warriors.

"Damn!" Yan Snake was completely dumbfounded, and shouted in a loud voice:

"Chu Yu, hurry, stop the lift!"

The reason why the first blind streamer of the apocalyptic wasteland is scared like this is very simple, the ladder lift is right in the middle of the tide of deformed monsters.

Chu Yu pouted and pressed the button on the lifting platform, but it had no effect, at most it only slowed down the lifting platform, but it couldn't stop.

As long as the lifting platform reaches the ground and the door opens, the three of them are in a group of deformed monsters, and there is nowhere to run.

Looking at it, it seems that the whole world is full of deformed monsters, not to mention fighting a bloody way to break through, as long as you go out, you will have to be overwhelmed by deformed monsters.

Chu Yu tried his best to calm down, only by calming down could he find a way to live.

This is what Chu Fugui taught him, no matter what death and desperate situation he faced, even if he hung up in the end, he at least fought it.

The brain is a very magical organ, and thinking is the most powerful weapon that the Creator has given to mankind.

There is no fate, there is no so-called arrangement, a person's life, the trajectory he has experienced, and the path he wants to take are all the results decided by the brain's thinking.

Only by thinking calmly can there be a glimmer of life.

Chu Yu took two deep breaths: "TMD, Lao Tzu only gives you five seconds of time to be afraid!"

After finishing speaking, Chu Yu began to count down: "Five, four, three, two, one!"

Dracula looked sideways: "Who are you talking to?"

"And myself!"

After finishing speaking, Chu Yu took out his binoculars and looked at the group of mecha fighting against the deformed monsters on the east side.

Dracula and Flame Snake glanced at each other, and the former Heihe smiled, "He was scared silly, talking to himself." ”

"Idiot!"

Yan Snake scolded, and he didn't know whether to scold Chu Yu or Dracula.

Dracula felt that the flame snake should scold herself, but she didn't know why she scolded herself.

Chu Yu was too lazy to take care of these two living treasures, and just focused on paying attention to the situation on the battlefield.

The number of mecha groups is large, only about a thousand.

But compared to the deformed hordes of deformed monsters like the sea, more than a thousand mechs are so insignificant.

These mecha are pure black, non-reflective, I don't know what material they are made of, about three meters, the streamlined design is very cool, the left arm position is a long black knife attached to the shoulder, a bit like a katana or a sword, and the right hand is a cannon attached to the shoulder.

This group of mechs also cooperated tacitly, with long knives approaching, artillery bombarding far away, advancing and retreating in an orderly manner, constantly consolidating the defensive line, trying to stop the deformed monsters from advancing forward.

Even so, this group of mecha warriors is not alone in the face of a large number of deformed monsters.

And about three kilometers behind the MechWarrior Warriors, a group of mechs that were clearly for construction were building a black structure resembling a fortress.

The fortress building covers an area of about 1,000 square meters, less than 100 meters high, with the fortress building as the center, extending more than 30 meters of high metal walls on both sides, directly connected to both sides of the valley.

The black fortress is a bit like a honeycomb, full of large and small holes, and I don't know what it is for.

Chu Yu roughly understood.

The MechWarriors are buying time for the rear builders, who are trying to set up makeshift positions and fortifications to try to keep the freaks from rushing into their hinterland.

The location of the black fortress is in the middle of the valley, and the only passable position in the middle of the valley on both sides is at least two kilometers wide.

Because of the angle, it is not clear in the telescope, but you can vaguely see that at the end of the valley there should be a city, a city that looks a bit like a huge fortress in the Middle Ages.

Chu Yu was surprised.

The place is a good place, you can attack and retreat, and the valley is an entrance and exit, but in this case, why didn't you build fortifications before, but only when the matter came to an end?

Thinking of this, Chu Yu was a little suspicious that this was a sudden incident.

The Freaks attacked suddenly, and the mechs didn't expect the Freaks to attack from this place.

Yan Snake scolded: "TMD, those birdmen are definitely playing tricks on us, there are several places on the ladder lifting platform, just let us come down from here, it will be a battlefield at once, and it is also a deformed monster camp, this is clearly asking for us!"

"Probably not!" Chu Yu calmly analyzed: "If Lilith and those birdmen want to kill us, they will kill us before you get older, so many birdmen with forks, we have no power to fight back at all, and Lilith has also provided a lot of information, if you want to kill us, why bother." ”

Dracula nodded, "I think so." ”

"Forget it, it's useless to talk about this, let's find a way, think about how we will survive after we get to the ground for a while. ”

After Yan Snake finished speaking, he took out all the firearms in the tactical bag, holding the "snake blade" in his left hand and the mp5 submachine gun in his right hand.

Dracula asked, "What are you doing?"

"Before strenuous exercise, it is not easy to strain the body, Li Yuwei told me. ”

Dracula let out an oh and started doing burpees.

While jumping, Dracula said, "I don't know how to use a gun, you can use the snake blade for me." ”

"Snake Blade" is a group of non-mainstream weapons opened in the H-101 area on the third floor before, and a weapon of nearly two meters can be retracted through the grip, saying that it is a knife, a bit like a knight's spear in the Middle Ages, it is said to be a spear, and it has a curve and a blade.

Eventually, the Flame Snake called this a snake blade.

"Use your sister, just hook the trigger at the monster group, so many deformed monsters, you can get there. ”

"Okay. ”

Chu Yu breathed very heavily, and continued to observe with a telescope, trying to figure out what was going on.

"Those wearing mechs should also be caught off guard, and at the moment, these freaks appeared very suddenly, otherwise they wouldn't have been fighting and building fortifications. Chu Yu wiped the cold sweat on his forehead: "There are too many deformed monsters, although those mecha look very good, in the face of a huge number of deformed monsters, they can't last too much time at all." ”

"Mecha, what mecha?"

Yan Snake immediately snatched the binoculars, and after taking a look, he waved his arms and shouted excitedly: "TMD, kill this group of deformed monsters, kill that group of mecha warriors, and grab the mecha." ”

Chu Yu rolled his eyes.

I was still thinking about how to run out in the last second, and after seeing the mecha, this guy actually wanted to eat it all!

"It's okay to do a little serious thing, whether you can live or not is two words, and Nima grabbed the mecha, dreaming. ”

"yes, it's a crisis. The flame snake observed for a while and said: "The speed of fortification construction is too slow, those mecha warriors can support it for ten minutes at most, and it will take at least thirty minutes to build fortifications, the gap in the middle of the valley is too big, and the fortress looks useless, unless it can be missiles." ”

Although the flame snake doesn't understand the black technology mecha, but he still has the vision, and after a little observation, he can evaluate the combat effectiveness of the mecha and the speed of building fortifications, and after a little analysis, he can understand that the winner of this battle is the deformed monster group.

As he said, so many mechs can't stop the deformed monsters at all, and the so-called fortifications are useless at all, no matter how powerful they are, you have to finish building them to make them.

And the number of deformed monsters is too much, and it is too late to follow one another.

Putting down the binoculars, the flame snake knew that it was still a few minutes before it landed on the ground, and twisted its neck, and broke out with a popping sound of bones rubbing.

"Let's fight to the death!" Glancing back at Chu Yu, Yan Snake asked seriously: "Do you follow me to kill some deformed monsters and then fight to the death, or let me kill you directly, and save you from being gnawed by those deformed monsters and die a painful death?"

Chu Yu scolded with a smile: "Your heart is too twisted, don't you, you still want to be the first to kill me?"

The flame snake didn't look like a joke at all, and said with a blank face: "Lilith said before that if you are devoured by this group of deformed monsters while you are alive, you will become a member of them, or become a part of their tissue, but if you die, you will not, at most you will be eaten by them." ”

After finishing speaking, Yan Snake patted the tactical dagger on his waist: "Fifty, kill fifty deformed monsters and I'll kill myself!"

Chu Yu opened the safety of the MP5 submachine gun, took out two more magazines and put them in his pocket.

"Fight to the death!"

"Okay, fight to the death!"

Dracula, who had been bobbying all the time, stopped and scratched his head: "You're all dying, can't you say some sad goodbyes to the occasion, such as being husband and wife again in the next life." ”

Flame Snake: "In the next life, we will be your father!"

Chu Yu: "... ”

"I was stretching when I was thinking about something. Dracula yawned and said, "We can use the subatomic ramming gun, wouldn't it be nice to step on the three of us all the way to get bigger, do we have to fight to the death?"

"I know incense, but the problem is that the energy is not enough. Chu Yu explained helplessly: "You used the subatomic collision gun before to finish the flame snake and the big tree spirit, and there is only more than twenty percent of the energy left, which is not enough to amplify any of us, you think I don't have a brain, I can think of what you can think of, and Lao Tzu can think of it without burpees." ”

"Oh, yes. ”

The flame snake didn't dare to say anything, because he didn't expect it, although he didn't know that the subatomic collider was running out of energy.

"See for yourself. Chu Yu took out the subatomic collision gun, and was about to throw it to Dracula, when suddenly he looked weird, as if he had seen a ghost in vain.

Because the energy of the subatomic collider actually shows 72 percent.

You must know that Dracula only had more than ten or twenty percent left after finishing the big tree spirit before, and he took a special look, it couldn't be dazzling, and the value showed that there was a progress bar.

The amount of energy released by a subatomic collider depends on the size of the object and the number of atoms, the larger the volume, the more atoms are constituted, and the more energy is consumed.

The energy used to amplify is greater than the energy used to shrink, more than twenty percent before, Chu Yu deliberately looked at it, because this energy was just enough for the flame snake to change back to its normal volume, and after the flame snake changed back for unknown reasons, the energy was always displayed at more than twenty percent.

Dracula magnified the flame snake, which consumed about twenty percent, and when the big tree spirit, consumed about fifty percent, it was not a dazzling thing at all.

"Damn, how can it be that it has recovered more than fifty percent?" Chu Yu looked at it several times: "The feeling is obviously only more than twenty percent just now. ”

Dracula leaned in, "When was the last time you observed?" ”

"I saw it when you finished the big tree spirit, and I was still thinking about transforming the flame snake back, just over twenty percent. ”

Flame Snake Heihe smiled, "Dracula will be careful in his calculations, and the energy that he will have to leave behind after knowing the Great Tree Spirit will make me turn back." ”

Dracula: "I didn't think about it at the time, I didn't even know how much energy the Great Tree Spirit used. ”

Flame Snake: "... ”

Dracula continued to observe the subatomic collider, muttering, "Could it be an automatic charge?"

"Automatic charging?" Chu Yu was confused: "Doesn't this thing have to be charged in the Tianshu Energy Converter in the Outsider Demon Civilization." ”

The flame snake reminded, "You can also charge it in that broken eight-hand van." ”

Dracula was also puzzled: "The subatomic collider can indeed absorb the energy of atoms in a fixed arrangement, and Chu Fugui will make a special equipment for atomic arrangement absorption and conversion to charge it, the problem is that this requires energy conversion... ”

Speaking of this, Dracula's face changed slightly, and he looked at the subatomic collider that had increased by one percent of his energy: "Unless, unless the entire underground world is a huge celestial energy conversion system, all of which are made of molecules, and they are also disordered molecules, and the subatomic collider absorbs the disordered molecules. ”

"How is it possible, the underworld is so clear ... When Chu Yu said this, his expression suddenly changed drastically, and he muttered: "After the surface creatures disappear, they will become deformed monsters and come to the underground world, and living things are also made up of atoms, and the components of deformed monsters are particularly chaotic, coupled with the extreme ecological environment... ”

Chu Yu couldn't go on.

Because he suddenly thought of an extremely terrible possibility.

Couldn't help but look at Dracula, and a trace of horror passed through the eyes of the two.

Only the flame snake shouted: "Don't talk so much useless, after opening the door in a while, I will clear the obstacles, and then rush out together and then zoom in, you seize the opportunity!"

Chu Yu nodded.

Don't think about the rest yet, let's live first.
