The structure of the legs is borrowed from some kind of bouncing cockroach, and all arthropods have tiny climbing spines at the ends, so that they can climb on smooth stone walls, making it easier to move through the cave.

In terms of body structure, Ye Ren did not follow the fragile structure of ants, but borrowed the body structure of beetles, so that the exoskeleton could ensure their safety to the greatest extent.

And after the body structure was roughly done, Ye Ren was surprised to find that in fact, this thing is quite like a cockroach, but this is not impossible, so Ye Ren smiled and began to continue to pinch, the mouth Ye Ren used a small but very efficient chewing mouthpiece, this chewing mouthpiece does not have a large jaw, only a small but extremely powerful jaw, and inside the jaw, two sharp exoskeletons form sharp teeth.

But this is not over, Ye Ren after thinking for a while, he transformed the arthropod closest to the mouthparts, making it harder and thicker, and at the tip of the arthropod, in addition to the climbing thorns, it was also transformed into a structure similar to a small clip, so that it could be firmly clamped on the hair or flesh, and it could not be shaken off.

In this way, this mouthpart specially born for group attack is very dangerous, although this pincer jaw is a little smaller, but due to the special structure, the biological tissue that is cut, torn or crushed by the pincer jaw will be crushed into smaller tissue fragments by the two incisors at the first time, and will be swallowed by the alien insects.

After thinking about it for a while, Ye Ren adjusted the arthropods into four pairs, and the inside of the first two pairs of arthropods was once again pinched out of the pincer-like structure and more climbing spines. Holding each other in this way can not only clamp the other person, but also pierce deep under the flesh with climbing spines.

and the last two pairs of arthropods. Ye Ren set it up as a structure that was good at bouncing and galloping, so that the speed was not too weak.

It's just that even so. Ye Ren was still not satisfied with this.

"If the main means of killing is to bite people, I always feel that I am a little undominant, but now I don't have any other genetic abilities..."Ye Ren frowned and looked at the cockroach-like insect in front of him, and said to himself.

"How should other parts be designed?" Ye Ren took the palm-sized cockroach-like creature in his hand and began to study it carefully, where can it be improved?

Ye Ren carefully observed the little cockroach, turning it over for a while, turning it over for a while, and turning it over completely. Finally, when I saw the small clip on the other party's forelimbs, I was suddenly stunned as if I had thought of something, and the whole person stayed there.

"That's right..."

Ye Ren realized that he had just forgotten the ability to drill into the ground, which the insect was best at.

"So with the current underground drilling speed of the alien insects, it is completely possible to ambush and attack prey underground, and there is no need to design a structure that must be comprehensive and hard, it seems that I have fallen into a misunderstanding. Ye Ren patted his head and immediately realized the crux of the problem, so he directly removed the two pairs of forelimbs. Began to continue to revise it.

Ye Ren's revision speed this time was very fast, because he had an idea for a long time, so he just realized the idea this time.

First of all, Ye Ren recreated a pair of forelimbs, which were slightly farther away from the mouthparts. However, the structure is very strong, and the size is not weaker than that of the hind legs, and there are several structures in the entire range of the arthropods. Normally, it curls up and splits into two parts. It is flattened and covered with a layer of special substance that 04 worms use to burrow into the ground, like two shovels that oscillate at high frequencies.

These two shovel-like arthropods. It is usually used to dig crypts, and the shape of the entire arthropod is flat and heavy, so it can also be used like a shield to block the attack of something when necessary.

But that's just a gesture of retreat.

The real shape is not only that, this is also the combination of arthropods that Ye Ren came up with after painstaking efforts, and it can even be said that it is the essence of this alien insect.

The shovel-like structure of this shovel-like arthropod is actually two separate structures, which are combined together to form a small shovel, but once its structure is opened, it becomes the third segment of this arthropod, an aggressive arthropod like a praying mantis's blade.

The dense sharp barbs between the second and third segments can easily pierce each other and get stuck in them, allowing them to be eaten by the insects.

It's just that in order to facilitate excavation, Ye Ren didn't set it up as the kind of structure of the mantis knife, because according to the structure of the mantis knife, the first two sections of the insect's arm are stretched forward, and they can't dig the soil behind them like waving a shovel, so Ye Ren directly reversed this structure and turned it into a structure similar to that of a praying mantis shrimp.

The third blade of the praying mantis is downward, but the blade of the third section of this alien insect designed by Ye Ren is facing upwards, although the direction is different, but it is not wrong to use it to attack the enemy if you think about it carefully.

Because the legs of the praying mantis are very high, it needs to attack the small insects below from above to hunt, but this insect designed by Ye Ren is convenient to burrow into the ground, and the chassis... In other words, the size of the bug is very low, so even if it attacks, it is necessary to attack the enemy above, and this structure is more suitable for them.

Moreover, such a structure can also use barbs to pierce the opponent's body, and then hook the opponent in front of the insect and jam it, which really does not affect the use, and even Ye Ren specially simulated the hunting process in the process of debugging.

After finding out that there was really no problem, I was relieved.

Ye Ren was very happy about this ingenious dual-purpose arthropod structure, and he clapped his hands and said to himself proudly: "I'm so TM and witty!"

"In that case, this thing should be pretty much the same for both large and small creatures. ”

Ye Ren looked at the palm-sized cockroach-like insect in his hand with satisfaction, the more he looked at it, the more he liked it, and after thinking about it, he specially added a pair of arthropods to assist in eating, this pair of arthropods is very small, and the use is similar to the previous one, that is, two short and thick small pliers, plus some climbing spines, which can firmly grasp the flesh or hair, or assist in eating.

In the end, after Ye Ren wrapped the whole body of this insect with a thick exoskeleton, he made the shape slightly smoother to facilitate movement under the soil layer, which completely finished the work.

"That's it!"

Ye Ren enlarged this insect to the size of a small car, and looked for the slightest loophole in its body with satisfaction and carefulness, but the result was that it could not be found at all, at least in Ye Ren's current opinion, this thing is really perfect.

"This thing... How do you name it?"

Ye Ren glanced at this pitch-black cockroach-like creature, thought for a while, and then found that he really didn't have the talent to name it, so he waved his hand: "Forget it, let's call it a cockroach directly." ”

"System, I'm done, how do I let the queen lay this egg?"

After Ye Ren thoroughly debugged the cockroach, he began to look up and ask the system: "Anyway, does this thing still need evolution points after debugging? I remember that this thing shouldn't be considered a debugging pool, right?"

"Creating offspring of subsystem organisms does not cost evolution points. ”

The system said to Ye Ren and dispelled Ye Ren's somewhat apprehensive feelings.

"Oh, that's fine. Ye Ren breathed a sigh of relief.

"The insect is defined as an aggressive insect in the list of the second subsystem creatures, the queen of worms, and the queen of worms will breed as a very aggressive combat class. ”

"Well, that's good. ”

Ye Ren nodded, and then rolled up his sleeves and prepared to continue drying.

"Come, next is the sapper bug ......"

It's just that just when Ye Ren was in high spirits and was about to continue to pinch the insects, the system suddenly interrupted Ye Ren: "The fourth-level domination ant colony of the postworm evolution has been completed, and the effective range of the domination insect colony has been greatly improved. ”

"It's been an hour. Ye Ren didn't look at the time when he fabricated the cockroach before, but now he was stunned for a moment after hearing the prompt of the system, an hour is not long, but it is not short, pinching insects can be done at any time, but the exploration of the cave must be completed first, so he immediately moved and immediately withdrew from the evolution space.

[Exit the evolutionary space.] 】

The surrounding space quickly blurred, and Ye Ren found that the surrounding environment immediately changed from a white world to a pitch-black cave, although it was daytime, but this was an underground cave world more than seven hundred meters below the ground, so it was still pitch black, and he couldn't see his fingers.

Because the portable lamp Ye Ren was placed in the stone room where Bai Mengmeng was, he couldn't see things clearly now, and he could only rely on the inductance and electromagnetic wave vision to see the surrounding objects, which was a little troublesome but okay.

And here, Ye Ren's consciousness had just recovered, and he immediately felt a smooth and warm object rubbing back and forth on his chest, and Ye Ren could tell that this was the queen of worms.

"Squeak~"

After the ability to dominate the ant colony was evolved by Ye Ren, the queen seemed to be very happy, because how far away she could control the range of the insect colony meant how far her territory was, which meant that she could breed more alien insects and spread into the territory, so happiness was certain, and she immediately used the spiritual link to send an intimate message to Ye Ren.

"Well, how much larger is the area now, can it cover the entire underground cave?" Ye Ren chuckled and stroked the skull of the insect queen, and then asked.

"Squeak~"

The queen sent a message of affirmation. (To be continued......)
