Ye Ming picked up the electrode and looked at it carefully, then took out the point manual printed under the box, and after careful comparison, he exhaled softly, and a smile appeared on the corner of his mouth.

The reason why two pieces were sent over was of course not because Tan Zhengming was thoughtful and bought one get one free, but because one of them was scrapped and had problems with two pins.

Because in essence, it is the nature of helping Ye Ming to get this, so Tan Zhengming only charged a cost, and then the scrap products were also sent over, so that Ye Ming could practice first.

In WeChat, Tan Zhengming also made it very clear that this thing is embedded in a flexible silicone sheet, and theoretically it is no problem to bend and deform, but after all, the electrode itself is very fragile, so try to be as leisurely as possible.

After reading the point description and finding that the other party really completed it according to his needs, Ye Ming clicked on WeChat and was about to send a message of thanks to Tan Zhengming, but when he thought that he would have to chat again after sending it, he simply threw his phone aside.

"Ita, I'm here I go."

"Come on!"

"Well, good luck to me - I think I should trade it for a focus boost, don't you think?" Ye Ming asked in his mind as he called out the system store.

The current exchange point stops at the beginning of 3600 points.

Ita thought for a few seconds and seemed to struggle violently before she made up her mind: "Good! ”

Ye Ming sighed: "Didn't you strongly recommend that I save up my points?" ”

"This one has a higher priority."

"Hmm...... Very high indeed. ”

……

With the blessing of the focus buff, Ye Ming entered the long-lost state of "forgetting things and me".

Swapping into the smallest welding torch head, picking up the tweezers, he started soldering the PCB board and the standard FPC interface.

Because of the consideration of bending, the electrode control chip that Tan Zhengming gave him here is also very simple, that is, a piece of cow is covered on an FPC (flexible circuit board - the yellow plastic sheet that can be bent with the mobile phone camera).

Fortunately, Tan Zhengming has made a standardized interface here, and he only needs to weld the interface and plug it in.

……

Ye Ming quickly completed the interface welding, and then he welded a small speaker on the head of the PCB, which was the size of a headphone tuning button.

After completion, he cheered up his spirit, connected the interface, and finally bent the silicone sheet to completely wrap the PCB board of the main control inside.

After sticking to it, Ye Ming stopped and rested for a few minutes even if he brushed the "BUFF", and then began to connect the Bluetooth headset.

To be precise, he wants to use the Bluetooth module and charging module of the Bluetooth headset, so as to realize the data transmission from the electrode to the main control chip to the Bluetooth chip to the mobile phone/notebook.

Time passed minute by minute, and when Ye Ming fixed the small horn at the very front with glue, he exhaled a long breath.

Before he knew it, his sweat had already wet his hair.

"It's done." He held up this headphone that was not like a headphone, and the brain machine was not like a brain machine gadget, and his eyes were full of irrepressible surprise.

This thing is similar to an Arabic numeral 7, the horizontal in-ear part is densely packed with exposed electrodes, the innermost part is a small speaker, and the vertical part is Bluetooth and battery life.

Because Ye Ming didn't know how the finished product was made, he didn't get the shell, and when he held it in his hand at this time, it was full of fragmentation.

Ita let out an "um".

"What? Not happy? Ye Ming picked up the T-shirt, wiped it directly on his forehead, and twisted a cotton swab to pound it in his ears.

It's about to be tested, and the earwax has to be cleared.

"I'm excited, but I don't know how to express it."

"That's the way you put it right now."

Ye Ming laughed, he put down the cotton swab, carefully picked up the tail of the electrode part, took a deep breath, and slowly stuffed the electrode into his ear.

The flexible silicone soon filled his entire ear canal.

Except that at the beginning, the exposed electrodes irritated the ear canal a little, and soon Ye Ming adapted to this stimulation.

Then, Ye Ming pressed the Bluetooth switch and turned on the notebook again.

After a smooth connection, he let out a long exhale.

"Come on!"

"Hmm!"

When Ita's words fell, Ye Ming felt a faint continuous tingling in his ears.

A moment later, Ita's voice rang out: "Proofreading complete." ”

"Very good, how often?"

"CONVERTED TO THE SPEED OF INFORMATION TRANSMISSION, IT IS THEORETICALLY 96KB/S."

"It's okay, it can be higher!" Ye Ming's eyes lit up: "I don't feel it now." ”

"No, the chip can't analyze so much."

"Oh...... Forget about this, okay, 96KB/S......" A smile appeared on the corner of Ye Ming's mouth: "There is no problem at all in browsing pictures." ”

"And now, you're going to give me the PC?"

"Yes, but wait, I need to change the Bluetooth device driver."

Ten minutes later, Ye Ming restarted the computer.

After entering the password to log in to the system, he lowered his hands.

I saw that the notepad page popped up on the screen without warning, and then, with a "swipe", a row of words appeared on the notepad.

"Tell me how I should quickly acquire the knowledge of each subject, whether it is through the Internet feedback or you prepare it for me, and I think that this dialogue with you can greatly improve my expression efficiency."

Ye Ming looked at this row of words that jumped out almost instantly, first stunned for a moment, and then he couldn't be happy.

"Internet feedback is fine, but I don't think you can extract useful information from the vast amount of information on the Internet."

"Where's the online library?"

"The online library is fine, but ......"

Ye Ming said in his mind, and suddenly stopped.

He could understand Ita's eagerness to learn quickly.

But...... Ita can now only learn through her own signal "relay station". That means he has to be.

It's okay to talk about the holidays, but what should I do when I go to class?

Go to bed...... Theoretically, it works, but it's so fragile in your ears that you might turn it over and GG.

After a few seconds of silence, Ye Ming smiled: "Don't worry, let's do a good job of planning for the future step by step, and even if you want to study, it is impossible to master the knowledge of all subjects, right?" ”

"Planning is an embedded brain-computer chip."

"Hmm...... But I think it's still a bit far away. And ......" Ye Ming said and narrowed his eyes: "Ita, have you ever thought about why you can talk to me in my mind, or in my consciousness." ”

Ye Ming saw that there was a pause in the notepad for a few seconds before the Chinese characters jumped out.

"It's not a task for me to think about."

"But that's what I've been thinking about." Ye Ming smiled, but his brows gradually furrowed: "Let's take a look." ”

"You say."

"First of all, what is the system? It must be a "system"—a system as we know it—no matter what it is based on or where it comes from. ”

"Go on."

"So, how does the system, including you, communicate with me?" Ye Ming squinted his eyes and looked at the void: "Under the existing scientific theory, human consciousness is generated by neuronal activity, which is manifested by bioelectric activity, and at the same time produces various different waves. ”

"You can use Vibo to interfere with my bioelectricity by wave resonance - can I think that your communication with me is actually a kind of interference, but it does not involve the aspect of bioelectricity."

Ita: "What kind of interference is that?" ”

"I don't know, I suspect it's a wave." Ye Ming retracted his gaze.

"Whether it's the arrival of the system, the generation of images in my head, or the fact that you speak in my head, it is a wave emitted by the system you are in, which ignores time and space and interferes and communicates with my brain waves."

"To achieve such an unreasonable exchange, I can only think that this wave can transcend time and space."

"And then?"

"And then?" Ye Ming's eyes narrowed very hard.

"If we can figure out what technology it is, it means we can use it to get the message across."
