As for why he is half invincible, it is because his alien insects can't fly yet, so the enemies in the sky are still a trouble.

"This thing looks good, system, let's fuse it into the body of the queen worm. ”

Ye Ren took out the gene ball of the air storage bag from the light curtain, and then said something to the system.

"Two hundred evolution points are required to fuse the airbag gene into the insect queen, do you want to confirm it?"

"Hmm. ”

Ye Ren nodded in confirmation.

"In fusion, the fusion time is expected to be less than an hour. "The system reported that it would take time.

"Well, I didn't expect this to be quite cheap. ”

Ye Ren nodded with satisfaction, the ability of this air bag is indeed much cheaper than the universal lung, and because of the special structure of the insect, Ye Ren cannot integrate the ability of the universal lung into the queen of worms, it's not impossible, but relatively speaking, it is not particularly compatible, probably the structure is not the same, just like Ye Ren's own genes that cannot be efficiently fused into the star mark.

Fortunately, Ye Ren bought a gene slot some time ago, otherwise, if there is no twelfth gene slot, there should be no way to fuse this gene ability, and he doesn't know how to worry about it at that time.

"You fuse the system first, I'm going to go out and see...... Huh?" Ye Ren stood up and was about to go out, but the moment he stood up, he suddenly thought of something, so he said: "By the way, system, I suddenly remembered that there was a deep cave bat gene before. What are the special vocal cords called, you can show me. I'm going to fuse it up. ”

"Okay. ”

The system responded, and then a ball of light appeared in front of Ye Ren.

"Is this it?"

Ye Ren glanced at this so-called special vocal cord light ball. In fact, although it is said to be the vocal cords, this thing strengthens not only the vocal cords, but also the structure of the entire larynx, the larynx, and the muscle distribution of the mouth and pharynx, as well as the sense of hearing and the extra small piece of brain tissue structure in the brain.

"System, the price of this thing...... Hmm, is it so cheap?" Ye Ren originally wanted to see the price of this thing, but only found out after taking a look. It's a little confusing that this thing is cheap, but it's only seventy evolution points for the first-level enhancement.

"Yes. ”

The system also began to release an explanation: "Because the enhancement of the vocal cords and auditory system does not actually modify most of the genetic structure, the price is slightly cheaper." ”

"Alright then, I should have two free gene slots, so let's fuse this thing together. ”

Ye Ren waved his hand, and then spoke: "You calculate the time and sue me." ”

"Estimated time, 10 minutes. ”

The system replied to Ye Ren.

"Oh, it's so short that you can fuse together. Ye Ren was stunned for a moment, and said, "Directly fuse." Don't ask me sure, I'm sure. ”

“…… Start blending. ”

After a moment of silence on the part of the system, it began to work.

And as the system worked, Ye Ren began to feel that his ears and throat became a little itchy. I opened my mouth and tried it, but I couldn't speak at all, and obviously I had temporarily lost the function of speaking because of the fusion.

Ten minutes passed very quickly, and Ye Ren just thought about his future development and plans. Here's the prompt of the system.

"After the fusion is completed, the first-level special vocal cord gene ability is obtained. ”

"Huh?" Ye Ren came back to his senses. Then immediately try to open your mouth and say a few words: "Melt so quickly...... What the hell am I wiping sounds!"

As a result, the sound was not right at all, and the voice went up and down. Full of magic......

……

Five minutes later, Ye Ren finally mastered the use of special vocal cords.

"The system, you're a bit of a pit, the first-level genetic ability can't even send out an ultrasound, are you sure you're not lying to me?" Ye Ren opened his mouth and complained to the system.

After Ye Ren figured out the gene of this special vocal cord, Ye Ren also knew the specific usage of this thing, in fact, it was a little interesting to say, this special vocal cord did not have the ability to emit ultrasonic or infrasound waves at the first level, and the ability it had was to make Ye Ren transform all kinds of timbres, to put it simply, it was to imitate other people's tone and voice to speak......

Although it was only seventy evolution points, to be honest, it was not very expensive, but the fact that he couldn't send ultrasound at all made Ye Ren feel as if he had been deceived.

The feeling of being deceived must not be very happy after all.

So there was this scene where Ye Ren complained to the system.

"There is a limited number of first-class special vocal cord genetic changes, so if you need more superior abilities, please evolve the genes. ”

After all, the system is just a mechanical program, and he can't understand Ye Ren's complaints, but simply repeats this sentence coldly, making Ye Ren feel that the system will never change, because it will always be so painful.

"Well, isn't it evolution?"

Ye Ren was playing with the system in the evolution space: "The scum system, give Lao Tzu a package that evolves to the fourth level." ”

With that, Ye Ren walked directly to the Evolution Pool and lay down in the emerald green pool water.

"To evolve to the fourth-level special vocal cords, you need 77,700 evolution points, are you sure?" Because Ye Ren did not directly confirm or remind the system, the system really came to ask for certainty.

“…… Are you sure. ”

Ye Ren rolled his eyes, and could only nod.

"Evolution begins, evolves, estimated evolution duration, 2 hours. "The system began to evolve special vocal cord genes, and the water in the entire evolution pool began to ripple slowly, and then some bubbles rose from the bottom, and finally the entire pool water boiled, as if it was boiling, and Ye Ren was lying quietly in the center, and the larynx and ears were changing.

It's not that Ye Ren didn't react, but because a wave of tiredness hit, Ye Ren couldn't help but fall asleep......

……

Two hours is not too much, less is not too much, after Ye Ren slept comfortably, the time was almost up, after the system prompted that the evolution had been completed, Ye Ren slowly opened his eyes, and then the whole person slowly stood up in the evolution pool.

"I feel like I'm a lot stronger this time. ”

Ye Ren felt the changes in the laryngeal muscles and vocal cords, nodded with satisfaction, opened his mouth and suddenly exerted force in front of him, and a cloud of ultrasound sprayed out of Ye Ren's mouth, and immediately stirred the degeneration pool on the side and began to tumble violently, like a large pot of boiling plasma.

"It feels good. ”

Ye Ren nodded in satisfaction, and then slowly closed his eyes.

The mouth opened slightly, Ye Ren released the ultrasound waves, and then soon these sound waves were reflected back after hitting the object, and were captured by Ye Ren's ears, and the sound wave sensory pituitary gland of the brain quickly activated, and in an instant, a general outline of the evolutionary space appeared in Ye Ren's brain, but because he didn't feel it with his eyes, these things only had outlines, but he couldn't see what they were or what color they were.

"I suddenly realized that I didn't seem to be a human anymore..."

Feeling his new ability, Ye Ren wiped his face and complained to himself: "I'm simply a monster." ”

But fortunately, this time the system did not run over to pick up the stubble.

"System, the queen of worms should have completed the fusion, the one with the air bag. ”

Ye Ren asked.

"Yes. The system answered.

"Well, then I'll go out and have a look. ”

Ye Ren nodded, and then said, "Exit the system space." ”

With his words, the entire space was like a mirror being shattered, Ye Ren instantly found that the surrounding space was quickly distorted, as if it was a mosaic, and when the blur slowly became clear, Ye Ren found that he was still sitting next to the insect queen, and Bai Mengmeng had already taken out the computer and was tapping because of the long wait, but the insect queen found that he had woken up, so he let out a happy insect chirp.

"Squeak~"

"Huh?" Attracted by the cry of the insect queen, Bai Mengmeng also shifted his attention, but when he raised his head, he happened to meet Ye Ren's open eyes, so he was stunned for a moment before reacting: "Are you awake?"

"yes, I'm awake. ”

Ye Ren nodded: "I just thought of a way, now I'll let you see how it works." ”

After speaking, Ye Ren slowly stood up and gave an order to the insect queen: "Come, insect queen, let me see the amphibious cattle insects." ”

"Huh?"

Bai Mengmeng was stunned for a moment: "What is that?"

"You'll find out in a moment. ”

Ye Ren didn't answer Bai Mengmeng, and patted the head of the insect queen with a mysterious smile: "Just produce an ordinary one, hurry up." ”

"Squeak~"

After hearing Ye Ren's order, the insect queen nodded very humanely, and then the tentacles trembled slightly, and began to reproduce slowly.

"Hey, what kind of fuss are you doing, you were just sitting here, right?"

Even Bai Mengmeng felt that this matter was a bit strange, so she couldn't help but ask curiously: "Did you just sit here in a daze? How could the queen of insects suddenly produce some amphibious cattle insects? What kind of trouble do you say about cattle insects?"

"You'll know after a while. ”

Ye Ren didn't bother to explain to her, although he said that he could trust Bai Mengmeng, but this matter was a bit difficult to explain, after all, the system was such a thing, even if Bai Mengmeng chose to believe it, but it would be too wasteful of time to say everything from the beginning.

"You guy don't want to hide everything and don't tell me......" Seeing that Ye Ren didn't seem to plan to sue him, Bai Mengmeng looked a little depressed. (To be continued......)
