More than ten hours later, Chen Chen stood outside the door of the X-ray radiology room of the research institute, flipping through the X-ray films in his hands.

Most of the X-rays are blank, and some have only a tiny dot on them, which can be ignored inadvertently.

These X-rays are what STEM chips look like under X-rays.

The so-called X-ray is actually a kind of electromagnetic radiation, but its wavelength band covers a wide range from 0.001 nm to 10 nm, which is located between ultraviolet and Y rays in the electromagnetic spectrum, and the corresponding energy range is from 125 eV to 125 keV.

People who are engaged in similar professional fields often refer to X-rays with a wavelength of 0.001nm~0.1nm as hard X-rays, and soft X-rays with a wavelength of more than 0.1nm.

According to the proportion of X-ray data penetrating carbon, soft X-rays with a wavelength of about 0.2nm or more can illuminate diamond-like substances with a thickness of more than 3 mm, and the core processor of STEM is a diamond-like crystal with a diameter of 3 mm.

The X-rays used for security checks are soft X-rays with low energy, so in principle, the chip is visible after it is implanted in the human body.

However, to Chen Chen's surprise, the motherboard material of the STEM chip is a special substance with biocompatibility, which is integrated with the human body.

In other words, even if the person who has been implanted in the chip takes an X-ray, it can only show the core processor of the chip, but it is difficult to find traces of the chip's motherboard.

And with the size of the chip's core processor, it is equivalent to stealth unless you are intentionally looking for it.

It is worthy of the high-tech chip of the future, and even this point has been thought of.

Chen Chen sighed secretly, but this is the opposite and cheapens himself, even if it is through the plane security check or even the X-ray inspection of the hospital, the concealment of the chip can be guaranteed to a certain extent.

"It's time to build your own team......"

Chen Chen muttered in a low voice, then destroyed all the X-rays, turned around and left the room.

……

"Mr. Samel—"

In the evening, when the researcher was about to leave work, Samel, who was checking the instrument, was stopped by Chen Chen.

"I'll invite you to come to the main control room later, I have something to discuss with you."

"As you wish."

Samel glanced at Chen Chen inexplicably, and then nodded.

Returning to the main control room, Chen Chen slowly poured two cups of cappuccino and put them on the table, then picked up a paper document on the table and read it with relish.

About ten minutes later, there was a knock on the door to the main control room.

"Please come in." Chen Chen raised his head slightly, and suddenly Samel pushed open the heavy iron door and strode in.

"Boss, you ......"

Samel was just about to ask something, Chen Chen shook his head, and at the same time pointed to the hand-poured coffee on the table, "Wait while it's hot, it'll be cold later." ”

“…… Thank you. ”

Helpless, Samel had no choice but to sit down opposite Chen Chen.

Smack!

Smack!

Smack......

A rhythmic tapping sound sounded, and Samel saw when he heard the sound, but it was Chen Chen tapping his index finger on the tabletop, and his gaze never took off the document in his hand.

Hmm, files?

Samel suddenly looked familiar, and from his own point of view, a paragraph on the document was not exactly ......

"Bang!"

After reading the contents of the document, Sam Elton slapped the table hard, and the coffee spilled directly on the table, "Boss, what do you mean by this?" ”

"What do you mean?" Chen Chen put down the file.

"I mean you read this file!" The anger in Samel's eyes almost burned, "Why is my file with you, what do you want to do to me?" ”

"Take it easy."

Chen Chen took a sip of coffee and said slowly, "There's a reason why I did this, before you get angry, listen to my explanation?" ”

"Whatever the reason, this national file shouldn't be on your desktop!"

Having said that, Samel still took a deep breath and suppressed the anger in his heart, waiting for Chen Chen's explanation.

"Mr. Samel, you were born in 1975, you are 46 years old, you married a Polish woman in 03, and you have a daughter after marriage."

Chen Chen read as he watched, "However, just ten years ago, on your daughter's seventh birthday, a car accident caused her to break her spine, resulting in paralysis of both legs. ”

"So, what do you want to express?" Samel said with a gritty grip.

"As far as I know, you used to be a medical bachelor?"

Chen Chen pointed out, "But after your daughter was disabled for life, you changed careers and began to study the field of stem cells, I don't know why?" ”

"Isn't that obvious?" Samel threw the question straight away.

"Is it because you want to save your daughter through your own efforts?" Chen Chen asked rhetorically, "However, when I first met you, you didn't seem to do that. ”

......Hearing this, Samel fell silent.

After a long time, he sighed, "That's right, I have studied the field of stem cells for ten years, and I have waited for ten years. ”

"For the level of modern medicine, only the field of stem cells gave me a glimmer of hope, so I gave up my favorite clinical medicine and turned to stem cell research."

"It's just that I thought that with my talent, I could find a cure for Anne, but it wasn't until I really got into this field that I realized how ridiculous my confidence really was......"

"So, you're waiting?" Chen Chen asked.

"Yes, I can only wait, waiting for stem cells or some other field to appear to cure cases of spinal injuries, but for so many years, I have never waited."

"I don't know how many years I'll have to wait, my daughter is seventeen years old, and while her peers are still enjoying their youth, she can only sit in a wheelchair and look at them with envy......"

Samel hugged his head and cried in a low voice, "I'm not a good father......"

"You're too self-defeating, Mr. Samel."

Chen Chen sat opposite, still expressionless when Samel revealed his true feelings, "Your academic level in the field of stem cells may not be the top in the world, not even the second tier, but there are still commendable points." ”

"That's it......"

Chen Chen said, took out a piece of paper again and put it in front of the other party's eyes, "If you can sign this agreement, I may be able to help you fulfill your wishes." ”

"You?" Samel's heart moved.

He used to be so arrogant that he didn't even pay attention to the company's shareholders, but as Chen Chen showed his talent, his attitude turned 180 degrees, and the changes in this made many people puzzled.

But only Samel himself knows that the reason is nothing more than pinning his daughter's desire for recovery on Chen Chen.

Although it is very slim, as long as Chen Chen can research a way to repair spinal injuries with stem cells, then his daughter has hope of recovery.
