The three monstrous monsters were bent and their backs were abnormally arched, each of them was almost two meters tall on their towering backs alone, and the huge white bone spurs that their hands formed were more than three meters long, like giant spears.

When their huge bodies ran and moved at speeds of more than eighty kilometers per hour, they were like a huge chariot with spears hanging on them, and they rushed head-on with a roar and great might!

For ordinary people, no, even the clone humanoid legion here, it is impossible to withstand the impact of those three monster tanks in such a tunnel space more than ten meters wide.

But here are the three war queens, and the three are at the top of their strength, no, it should be said that they are first-line war queens now.

Outsiders may not know, but for the three people who clearly know Leah's strength, the fourth-order strength can really only be said to be a first-line level.

But the first-line level of strength is enough for the current scene.

I saw that the three-headed double-spear monster in the charge suddenly had a shock, and the monster in the center suddenly stabbed the spear made of his hands towards his companions on both sides, and the two monsters running side by side were caught off guard and were stabbed to the waist by the spear.

The two monsters let out a roar of rage at the same time, and were knocked off balance by the tip of the spear, and instantly tumbled to the ground, not understanding why they were suddenly attacked by their superiors.

Fortunately, because everyone was running in the same direction, there was not enough distance for the monster in the middle to gather strength, which made the two monsters that were stabbed over not suffer any major damage---- whether it was stabbed in the waist, or fell to the ground and rolled dozens of meters, this was not enough to bring any big threat to their tough bodies.

Even if they stopped rolling, at most it would be a little pain in their flesh, which for their desire to kill and eat, this pain could not even make them care for half a second.

As long as they can stop their inertia, they can get up again, and then pounce on the four tender food again, and their simple brains even think that the superiors just now deliberately attacked them just now, just to make their movements slower so that they can't grab the food....

But their simple minds obviously ignore one point, which is that these few seemingly tender and delicious foods are by no means so easy to eat.

"Well done, let's go ninety-nine!"

Thorn saw that the monster in the middle suddenly turned back, and knew who was making the move, Amy's ability is no secret among humanoid girls, as a warrior who grew up in the battlefield, Thorn is most sensitive to the battle situation, she mastered the fighter plane for the first time, and rushed towards the monster that kept rolling in front, and her right hand, I don't know when she grabbed the handle of the long whip, and threw out the whip when she was about five or six meters close to the monster.

Syllable~!

The muffled sound passed back through her arm, and the whip exploded directly into the monster's waist in a blood mist!

Thorn's eyes were poisonous, and she could see that the waist of these monsters was one of their weak points, so her first attack was aimed at the wound from the previous miserable white bone spear, and the result of this whip was not unexpected by her, after the monster was blown out of the deep wound in the waist, it could not even struggle, and fell back to the ground with a wail of pain.

Thorn couldn't hear its wail, but she could feel the reverberation of the monster's struggle through the vibration of the ground, and with a smile on her face, she raised her right hand holding the whip lightly, and swung it down again, the whip landed exactly where the wound was, and struck the monster's entire waist in two!

The monster that had lost its lower body wailed even more miserably, its hideous face with a vaguely human face full of pain, but in the face of thorns, it was nothing more than a pantomime freak.

The corners of Thorn's mouth were raised, but her duty made her not forget to keep an eye on her teammates, and she glanced away, and Jiujiu's performance also satisfied her.

At this moment, Jiujiu was already standing on the body of the other monster, grabbing the severed monster head with his right hand, and returned to ask Zhang Yide for credit.

With the extreme speed of the ninety-nine-fourth order and the sharp bonus of its exclusive force field energy to the claws, she was the easiest to deal with these huge monsters among the people present.

"Zhang Yide Zhang Yide, look at you, Jiujiu is amazing~!The first to kill the enemy~!" Jiujiu stood in front of Zhang Yide, with an expression like 'praise me, praise me' on his face, and his tail was almost wagging up, oh no, her tail was indeed wagging up.

Zhang Yide looked at Jiujiu with an excited face, and almost thought that this was a dog who had just gone out to pick up a toy that had been thrown out and came back to ask for credit.....

He subconsciously reached out and touched Jiujiu's head, and Jiujiu also squinted and enjoyed the touch of the big hand.

"......." Zhang Yide almost blurted out a good word in his heart, but fortunately he held back, he withdrew his hand and walked forward, when he passed by Thorn, he seemed to see a trace of joy on Thorn's face, but Thorn's report made him ignore the strange feeling in his heart.

"BOY, is this monster going to be killed or left alive?"

"Kill it, there's one over there. ”

Zhang Yide's answer made Thorn smile on his face, and he took the whip and wreaked havoc on the monster on the ground that only had half of its body left, but the silent environment made Zhang Yide not know what was happening behind him, at most he could only 'hear' through the vibration from the ground that the monster behind him didn't seem to die so quickly.

Zhang Yide walked in front of the only remaining intact monster, and when he got closer, he felt more oppression from this monster.

This monster's body was larger than the other two, and it stood in front of Zhang Yide, as if as long as it stood up straight, it could condescendingly overlook Zhang Yide.

And its two miserable white bone spears that are more than three meters long exude a chilling oppressive force, as if as long as they are stabbed by this bone spear, even Zhang Yide, who has a force field shield, will be difficult to please.

Judging from the momentum alone, Zhang Yide estimated that this monster had reached the peak of the third order, and it was possible to enter the level of the fourth order at any time.

"Amy, are you having trouble controlling it?"

"It's not hard, it's just that the ghost energy consumption is a bit large, and I don't have the most convenient equipment like the eldest sister's head. ”

Amy replied that she could actually control the other two monsters together, but for the sake of the ghost energy reserve, she didn't do that, there are three battle queens here, everyone shares the effort, then everyone can maintain a better state.

"Hmm. Zhang Yide nodded in understanding, and then said: "Then can you check its memory, I am very curious about its origin." ”

Zhang Yide can tell from the appearance of this monster that it has a lot to do with humans, at least except for a little deformed, ugly face, and two bone spears on its hands, everything else is basically similar to humans....... At least it's a creature with only limbs.

And the appearance of such a monster in the shelter within this month has to make Zhang Yide have some ideas.

The defenders of the shelter in the month are those autonomous robots, and just now he looked at the corpses of so many autonomous robots along the road, but he didn't see that the remains of even one autonomous robot had a tendency to be infected and mutated, so does it mean that the autonomous robots will not actually be infected.

And when autonomic robots are not infected, where do these monsters come from?

It can't be the direct mutation of Chaos Spectral Energy after being infected with the soil, right?

That's not possible, and it's not realistic.

Therefore, Zhang Yide was curious about the origin of these monsters, he didn't know if these monsters were turned into other things in the shelter during the month, or foreign creatures, so he needed Amy to help him and see if he could answer some doubts for him.

"Yes, I'll try, but you'd better not get your hopes up too much. ”

Amy sighed lightly and was ready to do it, she knew very well that most of the memories of monsters mutated to this extent could not be retained, and the memories of human beings were pitifully fragile compared to the mutated cells, like ink dripping on lotus leaves, as long as there was a slight tremor, it would change its position and lose its form.

Amy wasn't sure.

And the truth is just as she thought, the mutant creature's memories before the mutation have all disappeared, and even the aftermath can not be found.

However, she was not completely unsuccessful, at least she found some unexpected clues.

"Boss, it's funny, it doesn't have any memories of the past in its head, but there is still a little bit of the most recent memory, I traced it and found that it still came from the passage on the other side. ”

"Hmm? What do you mean by the passage on the other side? Do you mean one of the three passages into the shelter?"

Zhang Yide frowned.

"That's right" Amy replied with certainty: "That's the kind of passage, but the passage over there has been tightly sealed, blocked with a thick metal wall, these monsters seem to have worked hard for a long time to get through, and then they were sent out by a monster that looks like a little more people, and the passage we just walked through was just discovered yesterday, and the attack was more than half a day ago.... Wait, I see, their big forces are still fighting more than a thousand meters in front of them!"

Although the information obtained is still very small, and he can't even construct a rough conjecture, Zhang Yide already knows the most critical point, that is, this shelter has not completely fallen!

Just over a thousand meters ahead, those autonomous robots are still desperately resisting!

Knowing this, it was much easier to do, Zhang Yide didn't have to think about anything else at all, and directly ordered: "Kill this monster, let's go directly to support those self-discipline robots!"

Amy replied. "Okay, ninety-nine. ”

"Ninety-nine knows!"

Jiujiu jumped up quite tacitly, and waved his claws at the neck of the standing monster, and the fresh head was in his hand, and Jiujiu didn't look at the head much, and kicked his little foot, and the head was kicked behind him like a football, and then, a whip volleyed into the air, and the head exploded in the air.

In this way, it is impossible for this monster to be resurrected anyway.

The group moved forward again, and the tunnel was soon near the exit.

Here, he noticed the hint of the goggles, and he seemed to have undergone an eerie gravity shift.

He clearly remembered that he was walking forward, but the data showed that he had skewed down about 90 degrees in a short distance of two hundred meters, and he should have pounced with his face facing forward after completing such a skew transformation, but he was still standing firmly on the ground, as if gravity had followed him to complete the change of direction and angle just now.

"There's artificial gravity here? When did it happen?"

Zhang Yide asked Zhan Ji beside him, he is a human being, he is easily deceived by his senses, if it weren't for the sensor reminder of the nanosuit, he wouldn't even be able to find out when gravity quietly changed direction, and the skew of the road was smooth and excessive, which increased the difficulty for him to find the abnormality.

And it is much easier for Zhan Ji to feel this, their senses are all-round, not just through gravity to feel, after seeing Zhang Yide have questions, the old thorn opened his mouth and replied: "BOY, have you just noticed? We have all turned one hundred and eighty degrees, strictly speaking, we are now standing on the earth's crust, and the core of the moon is on our heads." ”

“........ There was no control in the passage, and the change in gravity was so natural that if it weren't for the fact that the final angle change was a little more abrupt, I might not have noticed it until now. Zhang Yide once again lamented the technological sophistication of the shelter within this month, and then, he finally walked to the exit with a few battle queens and saw the scenery beyond the exit.

Beyond the exports, there is a huge steel city.

This city spreads all the way over, very vast, every building made of steel is neatly deployed in a piece of area, and Zhang Yide can see it, he actually found that these buildings spread in the past has an uphill arc, the uphill arc continues to extend, in the distance is blocked by the steel structure layer above, the city is layered, the height of the floor where he is located has a limit, about forty meters or so, to the steel ceiling.

He looked up at the steel ceiling above, and through the transparent high-altitude ladder on the side, he could see that the scenery behind the steel ceiling was also a steel building!

In other words, at least two floors of steel city have been built here!

Thorn also looked up at the scenery inside the sky and said, "I feel like we are walking inside layer after layer in a sphere, this experience is really strange. ”

"It's an adventure, an adventure. Jiujiu's eyes lit up and his tail fluttered and wagged, as if he was in a hurry to run up.

Zhang Yide asked Amy in a low voice: "The more than 1,000 meters you said, is it the distance we walked, or is it a straight-line distance?"
