In the previous life, almost all the people on the mechanical continent who could afford it had a crystal brain or a light brain.

What exactly are optical brains and crystal brains? To put it bluntly, they are a kind of supercomputer, but they are very different from supercomputers.

Crystal Brain is an intelligent body that exists physically, integrating scanning, analysis, data processing, information storage and other functions, which are completely obedient to human orders and help human beings make the most reasonable planning and choices at all times.

Aside from emotions, they have few drawbacks.

The light brain is a little more high-end than the crystal brain, the light brain has no physical existence, but it has the same ability as the crystal brain, the light brain can be carried around, it is very convenient, and the emotional mode of the light brain is much stronger than the crystal brain, it is because of these points, the light brain is more high-end and expensive than the crystal brain.

However, the top light brain is still not comparable to the top crystal brain, and the top crystal brain is much stronger than the top light brain because of various hardware materials and various configurations, so the speed and ability of data processing are much stronger than the top light brain.

Therefore, in the mechanical laboratories of major forces, top-level crystal brains are generally equipped to help mechanics analyze data and analyze various experimental parameters.

In his previous life, Ye Xuan had a top-level crystal brain and a top-level optical brain, and these two supercomputers helped him complete the mechanical design and manufacturing one after another, especially the optical brain, which even saved his life several times on the battlefield.

It can be seen that the importance of the light brain is self-evident.

Now that Ye Xuan has the opportunity to create a light brain, how can he not be happy?

With the light brain, all his actions can get twice the result with half the effort, and some things that need to be memorized, such as the names of tattoo medicines and elixirs, do not need him to memorize.

There are also all kinds of data analysis and processing, and he can let the light brain do it.

In short, the significance of the light brain is extraordinary, and Ye Xuan must engage in a light brain.

However, with Ye Xuan's current material conditions, it will definitely not work if he wants to make the simplest light brain for three or five years.

"Ah Xue, where did Stinky Lin go?"

Ah Xue shook her head, indicating that she didn't know.

"Forget it, let's go to my father, I want to go to Baiyun Village to have fun, and come back in the evening!" Ye Xuan turned over and rode on Ah Xue's back.

Ah Xue had no choice but to carry him to Ye Feng.

Originally, Ye Xuan planned to take Ye Lin to Baiyun Village to play, but after thinking about it, Ah Xue couldn't carry him and Ye Lin, so he didn't go to Ye Lin.

As long as she goes back quickly, Ye Lin must think that he is still in the secret cabin, so that she doesn't have to worry about crying if she can't find herself.

Thinking of Ye Lin's crying nose when she just came home that day, Ye Xuan's face couldn't help showing a trace of warmth, in this life, I don't seek to be famous in the world, I don't want to be arrogant, as long as I live ordinarily and make the people around me happy.

When Ye Xuan found Ye Feng, he was dealing with official business, and when he heard that Ye Xuan was going to Baiyun Village, Ye Feng wanted to send someone to protect him, but Ye Xuan refused.

"Dad, Ah Xue is so powerful, it's okay to have her. ”

Ye Feng thought about it, too.

Ah Xue's strength is very strong, and he is ruthless, and even he may not be able to beat Ah Xue.

So he nodded and said, "Then you settle down, don't make trouble for Ah Xue, Ah Xue, the brand will be handed over to you, protect him." ”

Ye Feng touched Ah Xue's head, Ah Xue let out a low roar, turned around and left the place where Ye Feng was dealing with official business.

Along the way, Ye Xuan chattered and talked non-stop.

"Ah Xue, don't be afraid when you get to Baiyun Mountain, no one dares to bully you. ”

Ah Xue didn't care, she heard that Ye Xuan recognized Bai Dayou as a godfather, and the bandits in Baiyun Village regarded Ye Xuan as a baby pimple, so she had to take a good look at Baiyun Village this time.

If it is really as Ye Feng said, then she may be able to mix one or two veined stones in Baiyun Village.

"You know, Bai Dayou, although he looks fierce, but...... And Sister Xueyin......"

Ye Xuan introduced the characters of Baiyun Village one by one, and when it came to the rise, he would also pinch Ah Xue's soft ears. Ah Xue was angry, but she didn't have a seizure, this little guy is really hateful!

Is there such a thing as an ear that can be picked up casually?

After talking for a while, Ye Xuan felt bored, so he tried to ask, "Ah Xue, do you want to talk?"

"Woo~"

Of course, she wanted to speak, but she didn't have mastered those rare tongue lines, how could she speak human language, and although she could understand human language, it was also very uncomfortable that she couldn't speak.

In fact, she has always wanted to communicate with Ye Xuan's family.

"Haha, wait a minute, don't resist!"

Ye Xuan said, already lying on Ah Xue's back, and his little hand probed Ah Xue's neck.

Ah Xue wondered, what does this little kid want to do?

Just as she was wondering, she suddenly felt a force surging in her throat, a little uncomfortable, but not uncomfortable.

"What are you doing, little one?"

When the words came out, Ah Xue was stunned.

Can you speak yourself?

Ye Yan heard her voice and was satisfied, in his previous life, he had dissected the corpses of some talking spirit beasts, and had done a rough study of the structure of the throat vocal cords of those spirit beasts, and now he helped Ah Xue change his vocal cords through Xuan Li, which was really feasible.

It's just that this is not a long-term method after all, and without the maintenance of Ye Xuan's power, she will soon be unable to continue to speak.

"Ah Xue, your voice is so good, huh?"

"I... I can talk, I can talk! Wow......"

Ah Xue jumped happily, she had been holding back in Ye Xuan's house for a few years, and she couldn't speak and communicate, it felt really indescribable!

"Ah Xue, don't be upset, if you throw me down, my father will talk about you again. ”

Ah Xue slowed down and asked happily, "Xiao Xuan, how did you do it, can I keep talking in the future?"

"Hmm... No, if I take my hand away, you won't be able to speak soon. Ye Xuan suddenly extinguished Ah Xue's enthusiasm.

"Ah, what should I do, Xiao Xuan, you must have a way, right, for the sake of Aunt Xue letting you ride for a year, you can help Aunt Xue!"

"Ah, Aunt Xue?" Ye Yan was surprised!

Ah Xue snorted lightly, "I'm about the same age as your father, it's not too much to call Aunt Xue, right?"

Ye Xuan nodded and said, "Then, okay, do you really want to talk?"

Ah Xue couldn't help nodding.

"Then, I can help you, but you must promise me that you can't teach others what I teach you, and you can't use what I teach you at will. Ye Xuan said very seriously.

Ah Xue Nunu mouthed, thinking that Ye Xuan was quite good at acting, but she still nodded hurriedly and said, "Yes, yes, whatever you say, I promise you." ”
