"If you come out of the system, I promise not to kill you......"

After Ye Ren heard the system's offer, he felt that the corners of his eyes twitched, 20,000 evolution points is really a lot, he only gave 1,800 evolution points when he killed a large beast before, and he only changed the changes in the exoskeleton slightly, and by the way, he just added two muscles, and he actually asked for more than 20,000 evolution points.

"Master, your request cannot be fulfilled by the system, the system has no entity. After hearing Ye Ren's words, the system still said in his dull electronic voice.

"Forget it, you cute. ”

Ye Ren shook his head, and he didn't plan to compare it with the system or anything, so he said: "Confirm it, isn't it just 20,000 evolution points, strong is strong, anyway, the system upgrade from level 4 to level 5 also requires 1 million, it's useless to save it for the time being, it's better to improve your strength first." ”

"Consume 20,000 evolution points and fine-tune to start ......"

After getting Ye Ren's affirmation, the system immediately implemented Ye Ren's request, Ye Ren felt that his nose and ears seemed to be a little itchy, and it seemed that his chest, shoulders or hands and feet also began to become slightly numb, but he was not a little sleepy this time, and it seemed that the debugging pool would not let himself enter a state of deep sleep when he was debugging.

Therefore, after a short period of waiting, after the debugging pool was debugged, Ye Ren noticed it as soon as possible.

Sure enough, as soon as Ye Ren reflected it, he heard the system prompt: "Debugging completed." ”

"Hmm. ”

Ye Ren answered, and then stood up from the milky white debugging pool, with the sound of rushing water. Ye Ren's whole person walked out of the debugging pool directly, and the hidden functions on his body were instantly lifted. Almost in a second, Ye Ren's naked skin immediately began to swell and become extremely black. Then a set of exoskeleton carapaces that emit a faint black light were formed.

At this moment, the exoskeleton carapace had been transformed according to Ye Ren's debugging, Ye Ren stretched out his right hand and tapped the breastplate a few times with the tip of his sharp right fingers, making a "knock" sound.

"The structure of the cuirass has changed slightly, it has become more resistant to impact, and the thickness has increased a little, well...... Defense has been strengthened a lot. Ye Ren looked down at his exoskeleton breastplate, which had become harder, and nodded with satisfaction.

Now Ye Ren's exoskeleton has been completely transformed according to the way he was debugged, whether it is the bone spurs on the joints of the shoulders and parts of the body. It is still the carapace that has been modified and thickened to protect important positions, and it has been completely transformed according to Ye Ren's own wishes, almost the same as the model in the debugging pool, and the climbing spines on the palms and soles of the feet and the lower arm are also very satisfying to Ye Ren, especially the two rows of sharp thorns on the lower arm that can be used as serrations and blades, Ye Ren almost likes it to the extreme.

Of course, Ye Ren also likes the specially thickened fist armor on his fist, and he almost can't put it down because of the fist armor he created.

"By the way, system, this exoskeleton shouldn't affect the current guò, right?"

Ye Ren, who was looking at his exoskeleton with joy, suddenly thought of something. Immediately asked the system.

"The scorpion-tailed exoskeleton is made from some kind of biological fiber that does not block or affect the flow of electricity. The system calmly explained, which reassured Ye Ren.

"Oh, that's good. ”

Ye Ren, who had been explained, was relieved. If this exoskeleton is insulated, it will be a big joke.

"Go out and try it, system, exit. Ye Ren looked at the black and shiny exoskeleton carapace on his body. Some of them couldn't wait, so they spoke to the system.

Subsequently. The space around him flashed, and Ye Ren found himself back in the Amazon jungle.

"Find some prey..."

Ye Ren, who was a little excited, ran to the top of a big tree. Then he looked around, trying to find some large beasts or something, so that he could also try what kind of progress his current strength had progressed to.

Ye Ren's eyesight is better than that of ordinary people, and standing on the top of the tree at this moment can naturally see the farther scenery, so Ye Ren quickly found a target, a caiman is lazily basking in the sun on the shore of the lake at the moment, looking quite leisurely.

"There you go. Ye Ren smiled slightly, immediately found the target, and the whole person jumped directly from the tree.

The caiman is a large carnivorous reptile in the Amazon basin, the largest length can even grow to more than four meters, even in the Amazon jungle, it is also considered to be in the upper reaches of the food chain, even the terrifying Amazonian snake, in its juvenile age is often preyed on by the caiman, a ferocious species.

In fact, the caiman that Ye Ren encountered at the moment, according to Ye Ren's visual measurement, was at least about four meters in size, but Ye Ren's strength had skyrocketed now, and a small caiman naturally didn't pay attention to it, and rushed directly towards the caiman, and one hand was clenched into a fist and hit it fiercely towards its head.

It's just that the caiman seems to have been alert, and the moment Ye Ren attacked, the caiman's head twisted, and he actually dodged this almost fatal blow.

"Boom!"

Ye Ren's fist covered with a hard exoskeleton carapace slammed into the ground, and the huge force directly knocked a cyan boulder on the ground with cracked traces.

And the caiman obviously felt the dangerous aura coming from Ye Ren's body, and he didn't care about anything else at the moment, so he turned around and ran into the water, don't look at the crocodile's four feet seem to be very dull, but the speed at which they sprint is indeed not low, and they ran far away in an instant, and they were about to enter the water.

"Do you still dare to run?" Ye Ren sneered, his toes bent to increase his grip, and then the whole person kicked the ground violently, like an arrow off the string, and rushed towards the caiman, grabbing the caiman's tail.

“！”

The caiman felt a huge force transmitted from his tail, and he didn't know if he had sensed that there was no hope of escaping, so he turned around fiercely and bit towards Ye Ren.

And in order to test the strength of the exoskeleton, Ye Ren didn't even dodge.

"Quack!" With the sound of teeth hitting the exoskeleton, Ye Ren suddenly felt a strong pressure on his arm, but Ye Ren specially looked at the exoskeleton twice, and although the place bitten by the caiman was slightly deformed, it was not broken.

It seems that due to the special structure of his exoskeleton carapace, he really has a certain toughness, and he will not be cracked by a bite.

I really don't know if the exoskeleton of this scorpion-tailed bee comes from the magic of nature, or if it has evolved its life structure through its own system to become what it is now, those hollow small black fiber tube structures Ye Ren thought about it, it was really a bit powerful.

"It's okay, I can bear it, although it hurts. ”

Seeing that his exoskeleton was not cracked or directly shattered because of this, Ye Ren couldn't help but praise the exoskeleton that he had spent more than 20,000 evolution points to strengthen, this sex price was not inferior even compared to the cockroach genes on his body, with a defense power like this Cheng Dù, Ye Ren felt that he would be much more convenient in many things, and he didn't have to be afraid anymore, otherwise it would be very troublesome to do anything.

"Okay, you've bitten enough, right?" Seeing that his exoskeleton was fine, Ye Ren naturally wouldn't let the crocodile continue to gnaw on himself, so he directly broke the crocodile's mouth with one hand, and then stepped on the crocodile's mouth with one foot, making it unable to move, and then ended its life with a punch.

"Looks like the power is a bit too much..."

Ye Ren looked at the layer of blood and brain pulp sticking to the carapace, a little helpless, it seemed that he still couldn't perfectly control the sudden increase in strength points by nearly twenty points, and just now he actually directly exploded the crocodile's brain.

But after all, it was just a crocodile, and after complaining casually, Ye Ren ignored the crocodile's corpse, and instead raised his hand and talked to himself.

"Next up is the ability to serrate and climb claws. ”

After deciding on the next goal, Ye Ren casually found a tree, raised his forearm, and aimed at the trunk with a row of counter-blade barbs on his forearm, and pulled left and right a few times, and the whole tree was sawed out of a big gap, and it made a crunching sound, and fell directly to the side.

"The cutting ability is also good, and in some cases it can be used for some weapons. Seeing the fallen tree, Ye Ren nodded with satisfaction, and then found another tree, and climbed to the tree with a few strokes of his hands and feet.

Halfway through the climb, Ye Ren stayed on the trunk of the tree, firmly fixed himself on the tree with the toe barbs of his two feet, and then tried to move the whole person, feeling very flexible, much lighter than climbing the tree before, as if the design of his exoskeleton was born for climbing.

"The next thing is to slowly experience it in actual combat... But before that......"

Looking at his black and shiny exoskeleton carapace, Ye Ren was very happy, but then he squatted on the ground and suddenly pinched an ant: "What's the use of trying a fourth-level insect communication." ”

After speaking, the tentacles on Ye Ren's forehead slowly swayed, and a fluctuation or frequency that Ye Ren couldn't understand emanated from his tentacles.

The ant that was pinched in Ye Ren's hand was still struggling desperately, but after Ye Ren's tentacles began to tremble slightly, it seemed to feel something, and suddenly quieted down, and the two small tentacles kept swinging, looking up at Ye Ren with its small head up.

It seems that something is being communicated. (To be continued......)
