The middle cavern was indeed huge, but they still didn't have any accidents passing through it, leaving corpses along the way.

After arriving at the passage between the middle cave and the inner cave, Zhang Yurong stopped and said with a relaxed face: "These insects are not powerful." ”

Chen Guo also said: "That's right, the ability can't be used, that is, the energy magazine consumes ten." ”

Fang Fang checked the energy reserve compartment of the levitating magneto-light cannon, replaced the depleted energy box with a new one, and said, "Why don't we kill all the insects here, we can get more crystal nuclei, and Dad can upgrade more powerful technology." ”

"Let's go inside and check the situation first, and then weed out these monsters." Ye Guchen said, and immediately contacted Wu Hao and asked, "How is your situation, is there any special monster in the inner cave?" ”

"Of course there is, these guys are very thieves, all concentrated in the inner cave as if waiting for you, I don't dare to show my head now." Wu Hao's voice appeared in their heads.

"What kind of monster?" Ye Guchen asked again.

"A monster taller than a human can stand like a praying mantis, its forelimbs are like two scythes, and its armor is so hard that a tyrannosaurus gun can't penetrate it, I tried it just now, but it just popped out a few notches in its hard armor. There are many of these monsters, and there are two insect kings, who seem to be wise and can communicate, one is like a fat earthworm, and its mouth is full of teeth, and it is scary to see. The other resembles a humanoid, with four arms and four legs, two arms are like pincers, and two sickles are the same, anyway, they are very powerful, and the hard crystal is easily cut off and bitten. I've tried, I've got crystals. Wu Hao said what he knew in one breath.

Ye Guchen frowned and analyzed: "No wonder it feels very easy to kill in, this is a trap for us, and you want to make us dumplings, it is estimated that we have walked through this passage, and the insects behind will definitely block the passage, this is a closed door and a dog." ”

Chen Guo said: "I filled the caves inside with corrosive black gas, and if they were sealed, they would be dead. ”

"Well, that's a good idea, we'll stay in the passage, it's relatively small here, they'll come over one or two at a time at most, and we'll spend it with them here."

Ye Guchen agreed, Chen Guo immediately ran to the entrance of the inner cave, stretched out his hands, corrosive black gas gushed out, the insects guarding the inner cave were frightened, they were originally hiding, but now they all rushed out, the black gas engulfed some of the insects, Chen Guo showed a smug look.

At this time, suddenly a praying mantis insect pounced on Chen Guo through the black qi, and the forelimbs of the sickle slashed down. Chen Guo was surprised, for the first time, a creature could pass through her corrosive black qi, which surprised her, causing her to be half a second slower and unable to dodge.

At this time, the dark blood shield appeared, and instead of her, she blocked the mantis insect's scythe, this bug's attack power was really strong, and the scythe actually pierced into the shield section.

At this time, Chen Guo retreated and exclaimed, "How can this insect not be afraid of my corrosive black qi!" ”

"I'll try."

Zhang Yurong released the flames and rushed out, the mantis insect was repelled by the flames, and the high temperature made it scream, but there was no change in its body, and it could still stand up and crawl over in the flames, and the hard armor on its body was slowly burned red.

"Damn, is this a bug!" This time everyone was surprised.

Wu Hao suddenly came out from their feet and shouted: "This can't be fought, the bullets can't be moved, now it's useless even your abilities, it's better to retreat." ”

"There can be no invincible creatures, it's my turn." Ye Guchen released the dark blood mist, and the red mist rushed out of the cave, these mantis insects were still struggling in the high temperature just now, this time it suddenly changed, and the blood mist quickly filled here, but the result was still the same, these insects were not afraid of devouring ability.

After Ye Guchen was surprised, he suddenly found that the crystals here were also unaffected, which may be the reason why these insects ate the crystals, causing the body to mutate.

Just as Ye Guchen was about to retract the dark blood mist, a large number of cyan ant dogs gathered in the middle hole behind him, completely blocking their retreat.

Ye Guchen frowned and said: "Wu Hao, get a crystal, I have to analyze the composition of these things and find a way to restrain them, otherwise we will have to go back." ”

"Okay." Wu Hao immediately burrowed into the ground, although he couldn't cut the crystal, he could dig out the whole crystal and take it away.

"My electromagnetic whip just now is effective, maybe it can deal with these praying mantises as well." Zhang Yurong said, rushed to the entrance of the inner cave, and threw out the electromagnetic whip and touched one, sure enough, electricity is the nemesis of this kind of bug, and it will die quickly if it touches it.

Seeing this, Ye Guchen said: "Fangfang, you and Rong'er guard the entrance of the inner cave together." Guoguo and I guarded the hole in the back. ”

"Okay."

Ye Guchen and Guoguo shot at any cost, but fortunately, the hole was small, and they could still hold it under the intertwining of the firepower of the two. Fang Fang's firepower is powerful, and the magnetic light cannon can be as lethal as a frontal hit against the mantis, but these mantis have stronger vitality than the cyan ant dog outside.

After persisting like this for about five minutes, Wu Hao came out of the ground with a large piece of crystal, handed it to Ye Guchen and said, "It's enough." ”

"That's enough." Ye Guchen's hand touched the crystal, and he immediately put it into the research room and let the computer analyze the ingredients.

Then Wu Hao joined Chen Guo to shoot, and the mantis worm used the tyrannosaurus gun to no avail. The insect king felt impatient, and the earthworm-like insect king let out an ugly hissing sound, and the mantis insect at the entrance of the inner hole immediately retreated.

Zhang Yurong felt that something was wrong and immediately shouted: "Be careful, the earthworm king is about to act." ”

This reminder everyone looked at the earthworm king, only to see it open its mouth, and a crystal spike with the thickness of an adult man's arm shot out, as fast as a sniper rifle, and even they didn't have time to dodge.

The first one pierced a levitating magneto-optical cannon through Fangfang, then pierced her shoulder, and then shot past Chen Guo's ear, piercing her ear, and finally this crystal spike rushed into the stone wall above her head, disappearing, and the hole seemed to be pierced very deeply.

This shocked everyone, the Nightkin suit was pierced like paper, Fang Fang covered the wound in pain, and cold sweat broke out on her forehead, but the ferocity of the mutant did not make her weaken her combat power, but aroused her ferocity.

Under the dilated pupils, the telekinetic wave rushed out, and the insect king was actually frozen, and then the five levitating magneto-light cannons shot intensively, and the energy light bombs concentrated on the insect king, and the energy of the instant explosion engulfed the insect king.

Fang Fang continued to bombard in anger, until after the venting was finished, the levitating magneto-light cannon stopped, and after the dust and smoke from the explosion in front of him dissipated, she saw the humanoid insect king blocking in front of the earthworm king, with limbs and arms protecting his head.

The magneto-light cannon had only left a small scorched mark on its hard armor. This shocked Fang Fang, and was just about to use his telekinesis to freeze the other party again, when suddenly the figure of the humanoid insect king blurred, and then appeared in front of Fang Fang, and the two sickle arms cut left and right at the same time.

At this time, Ye Guchen rushed behind Fang Fang and hugged her, his body was wrapped in the dark blood shield, and the left and right arms of the sickle hit the dark blood shield at the same time, and the tip of the knife pierced into a part, and it was still slowly advancing.

Ye Guchen knew the defensive power of his dark blood shield, and the missiles could be defended head-on, but he was cut into it so easily by this bug.

Zhang Yurong's electromagnetic whip was thrown out, wrapped around the neck of the humanoid insect king, and the electric current stimulated its body, making the insect king roar angrily. Later, the earthworm king opened his mouth again, and Chen Guo, who had already prepared, opened the Lingyun Bow and shot out.
