"Oh, I know. ”

Ye Ren nodded, he actually knew this for a long time, after all, the exoskeleton was included in the skin, although he didn't know how the system did it, but the exoskeleton was gone, and it could be said that the defense power was greatly reduced.

After that, Ye Ren tried the recessive function several times and roughly determined the time when this recessive function was activated.

If it is hidden, the time may be a little longer, generally about ten seconds or so to retract the exoskeleton armor into the body, and the insect tentacles are faster, about five seconds, but if it is to cancel the hiding function, it will be much faster than turning on the concealment, Ye Ren calculated, the exoskeleton only needs less than a second to appear, and the tentacles can also appear within two seconds.

In the recessive state, Ye Ren carefully observed his skin, as if he couldn't see the characteristics of the exoskeleton armor at all, but once the recessive function was turned off, his skin would rapidly expand and turn black and shiny within a second, turning into an exoskeleton armor emitting a faint black light, which was faster than Ye Ren imagined.

"Okay, the next thing is the debugging pool..."Without too much research on the implicit functions, Ye Ren turned his attention to the new pool that appeared after the system upgrade, the debugging pool.

It was no different from the feeling of lying in the evolution pool before, Ye Ren was lying in the debugging pool this time.

When Ye Ren was lying in the debugging pool, his eyes suddenly went dark, and an image of himself that seemed to have shrunk appeared in front of him, according to the information that the system had input into his mind before, this meant that the debugging pool had been activated. The virtual self in front of you is the template, and you can modify part of the physiological structure and even the entire appearance of your template through guò consciousness. After the modification is completed, the system will automatically evaluate the number of evolution points that need to be collected.

Compared to the two systematic functions of evolution pool and degradation pool, this debugging pool is indeed a very flexible and free function.

The mind moves. Ye Ren took a piece of exoskeleton carapace from his template, and then enlarged it, after enlarging the nails-sized fragments of the exoskeleton carapace, Ye Ren finally saw the structure of his carapace clearly, which was a very small black tubular fiber, layer upon layer, intersecting together, tightly and intricately woven into the fragments of this exoskeleton armor, the inside of these small tubular fibers is hollow, and has a certain toughness. It looks sturdy and lightweight.

"I wonder if the exoskeletons of other insects are the same structure..."

After seeing the structure of the exoskeleton, Ye Ren couldn't help but sigh at the magic of nature, no wonder the carapace of the scorpiontail wasp was so hard, it turned out that the carapace structure of this thing was so exquisite, at least Ye Ren didn't figure out how to debug his exoskeleton structure from a microscopic perspective for the time being.

I don't know if the structure of this exoskeleton was like this at the beginning, or if the system was optimized like this after evolution, in short, this structure made Ye Ren a little surprised, and even a little at a loss.

However, although he can't start from a microscopic perspective, Ye Ren can also change the shape of the exoskeleton carapace on his body.

Ye Ren first carefully looked at his exoskeleton carapace. Then he peeled it off from his body, but as soon as the exoskeleton carapace on the model was peeled off, there was even a large piece of blood on the model's body, and there was no skin. It also scared Ye Ren.

"Exoskeleton replaces skin?" Ye Ren quickly thought of the problem.

"Theoretically, the exoskeleton of insects is very good, but because of the physiological structure of insects, they can only use a tubular respiratory system, not a negative pressure respiratory system. So the oxygen utilization rate is low, but I don't seem to have this problem..."

I briefly recalled the information I had consulted. After Ye Ren closed his eyes and thought for a while, he relieved his heart. Although the exoskeleton replaces its own skin, but this is just a combat form, once you usually turn on the recessive function, the exoskeleton carapace will still become skin, so this doesn't cause much trouble, compared to the strong defense brought by the exoskeleton, these problems are not a problem at all.

Thinking of this, Ye Ren began to carefully observe his exoskeleton carapace.

The exoskeleton that cost more than 20,000 evolution points is indeed worthy of this price, the entire exoskeleton carapace is glowing with a layer of dark light, all the joints are also very tightly protected, and the whole body except for the mouth, ears and nostrils, even the eyes are blocked by a layer of translucent dark red crystal plates.

It's just that I don't know if it's a bit of a problem with the aesthetics of the system, most of the shapes of the exoskeleton carapace are arc-shaped, and they are very smooth, and they do look similar to some insects.

After thinking about it for a while, Ye Ren began to adjust the appearance of the carapace.

First of all, the thickness of the carapace was slightly adjusted, and the critical parts were focused on increasing the thickness for good protection, and the parts that needed to move flexibly were slightly reduced in thickness to facilitate movement, and Ye Ren specially used the exoskeleton to create some sharp and sharp bone spurs, which were very effective for dealing with pythons, and if there was a giant python that wanted to wrap around Ye Ren, it would definitely be covered in bruises before that.

In addition, Ye Ren also specially thickened the carapace of the fist part, so that Ye Ren's fist was as lethal as if he was wearing steel fists.

Originally, Ye Ren wanted to make a sharp claw like Wolverine, but the system kindly reminded Ye Ren that the exoskeleton is not an Edelman metal after all, and this structure is not only not suitable for force but also easy to break.

Ye Ren also made a series of fine-tuning of the exoskeleton tested in the soles of his feet and palms, in fact, it was nothing more than creating countless inward micro-saws, which could be like climbing spines brought by spider genes when Ye Ren climbed, shallowly piercing into the objects he was climbing, so that Ye Ren himself would not fall.

In addition to the soles of his feet and palms, Ye Ren also created a large climbing thorn on the carapace of each toe.

This climbing thorn is like a nail on a skate, which can be bent by the toe to pierce the object, and then gain a firm grip, and through the large or small barbs, Ye Ren can easily cling to many things, whether it is a tree or the body of a wild beast.

This kind of large barb is also found on Ye Ren's forearm, but the one on Ye Ren's forearm can no longer be said to be a climbing thorn.

Ye Ren's forearm extends from the wrist to the elbow is lined with a row of about two or three centimeters of reverse bone blades, the sharp blade tips are all neatly arranged towards the elbow, these bone blades are like a row of serrations, not only can be used to hook objects, but also can be used as sharp saw blades or blades, which is very convenient.

As for the fingers, although there are not as many climbing spines on the toes, Ye Ren has designed the fingertips of his fingers into sharp claw shapes, just like the nails of an eagle, which also have excellent grasping ability, and can also lightly pierce into tree trunks and some animal body tissues.

"System, settle it. ”

After completing the change in the appearance of the exoskeleton, Ye Ren said to the system in his heart.

"The settlement is complete, master, you have adjusted the appearance of part of the genetic structure of the exoskeleton, the changes are medium, the performance evaluation is excellent, and a total of 5,000 evolution points have been spent, are you sure?"

"It's so expensive..."

Hearing the number of five thousand points, Ye Ren was also stunned for a moment: "I just adjusted the thickness and shape to be so expensive?"

"After the owner's debugging, the structural performance of the exoskeleton gene is very good, so it is not expensive to charge 5,000 evolution points. ”

The system explained.

"Really?" Ye Ren rolled his eyes: "Then you wait, I'll continue to debug ......"

"Okay. ”

After hearing Ye Ren's words, the system still replied in a calm and dull tone, and then there was no sound.

This time, Ye Ren did not simply adjust the exoskeleton, because the exoskeleton has been adjusted to the limit by himself, and Ye Ren has been unable to adjust anything on the exoskeleton for the time being, and his target this time is his own muscles.

After studying his muscle structure and nerve connections for a long time, Ye Ren added a small piece of carefully manufactured muscle plexus inside his nose and ears, and their ability is also very simple, that is, when he wants to, the nose and ears are tightly closed, and then the hard exoskeleton will firmly hide them under the carapace to prevent some things that should not go in from taking the opportunity to get in.

Whether it's a bug or a liquid.

In fact, this ability was not thought up by Ye Ren himself, Ye Ren glanced at his lower body more evilly, because of the exoskeleton, his little partner has been completely hidden inside the hard carapace, only when Ye Ren thinks about it, Xiao Yeren will emerge from the crack in the carapace.

So Ye Renzheng copied his body in the open, and made the same defensive measures for his nose and ears.

"Okay, system, you can settle it again this time. ”

Ye Ren, who was busy, wiped the sweat on his forehead, looked at his template in the consciousness space with satisfaction, and said to the system in his heart.

"The settlement is complete, master, you have adjusted part of the appearance of the genetic structure of the exoskeleton, increased part of the structure of the muscles of the body, the modification process is medium, the performance evaluation is excellent, and a total of 20,000 evolution points have been spent, which is close to all the evolution points you have, are you sure?" The electronic voice of the system sounded in Ye Ren's mind.

"If you come out of the system, I promise not to kill you......" (to be continued......)
