Chapter 1006: 985 It Was Wrong from the Start

"It's different; the sympathetic nerve part isn't involved in heart transplants." Su Yun replied.

His face showed a rare seriousness; once he started talking about heart transplants, a professional aura and confident emotion welled up.

"How much do you know about detecting the nervous system?" Zheng Ren asked.

"I'll ask my research friend." Su Yun took out his phone and began flipping through the address book.

Zheng Ren felt moved; someone as sharp-tongued as Su Yun actually had friends all over the world. When he previously came to Di Du to participate in the prostate project, Fang Lin and Zhao Yunlong heard the news and came, dragging him out for drinks.

In Hai Cheng, he knew that little girl from the Cat-Dog House, and their relationship wasn't bad either.

Now, if I wanted to ask about nervous system detection, he could just pick up his phone and find someone to consult.

Could it be that people nowadays all like sharp-tongued guys? Or is it that good-looking people are naturally destined to be loved by everyone?

But that doesn't matter; Zheng Ren wanted to know what equipment could detect nerves, then check if the System Space had it for sale.

One shouldn't buy blindly; experience points can be considered universal points, able to buy equipment and also surgical training time. This kind of thing is like money—who would complain about having too much? Since having the system, I seem uninterested in money, perhaps because there's a better equivalent exchange method than money.

Zheng Ren, utterly distracted, sank into contemplation, his thoughts flying beyond the nine heavens.

Soon, Su Yun's side received the news.

"A neural current sensor costs over a hundred thousand domestically, even more for imports. Boss, what do you need this for?" Su Yun found it strange and asked.

"I always feel that patients with renal artery stenosis need surgical dissection, but nerves—you know, you can't just mess around with them." Zheng Ren sighed, and having said that, no matter how Su Yun questioned him, he wouldn't continue.

Many words lead to loss; the ancients never deceived me.

Just give Su Yun a clue, and he'll follow the thread to find more things that need my explanation. As for matters involving the system, it's best not to talk about them.

Su Yun was merely a bit puzzled; no matter what, he wouldn't think of the system being that big pig trotter. Seeing Zheng Ren's mood slightly odd, he guessed perhaps the renal artery stenosis patient's condition hadn't broken through, so he comforted Zheng Ren a few words and went to rest.

Returning to the System Space, Zheng Ren opened the System Mall's panel and browsed through the categories one by one.

Neural current sensor……This kind of thing is generally used by people doing basic research; surgery basically doesn't need it.

After searching for about twenty minutes, Zheng Ren finally found, in a rather low position, that the System Mall indeed had a medical neural current sensor.

200,000 experience points……

Seeing this price, Zheng Ren nearly spat out a mouthful of old blood.

One day of surgical training time is 86,400 experience points; a neural current sensor actually costs more than two days' worth of surgical training time.

Really——damn it.

Zheng Ren hesitated resentfully for a while, but finally clicked to purchase. After all, this could be considered an investment, expecting greater returns. Moreover, Zheng Ren was also curious about the side effect of radiofrequency ablation causing blood vessels and nerves to stick together.

A black, textured little thing appeared before Zheng Ren. Zheng Ren didn't even bother to admire the system's black tech; he watched as a large chunk of his surgical training time vanished, feeling heavy-hearted.

Along with the neural current sensor falling into Zheng Ren's hand came a user manual.

Zheng Ren read through the manual once, feeling some emotion about how difficult basic research really is. But now he had no mind to think too much; after splurging once, the primary issue to face was the shortage of surgical training time.

Better to do more tasks, ignoring task rewards; it seems wrong otherwise. Zheng Ren corrected some of his behavioral mistakes, re-entered the System Operating Room, and began another surgery.

The experimental subject remained in the lateral decubitus position, layer by layer dissection, reaching the renal artery stenosis site. Zheng Ren carefully separated the renal sympathetic nerve fused with the blood vessel, his technique delicate and gentle, performing at 120% of his ability.

After isolating a corner, Zheng Ren attached the neural current sensor's wiring to it.

Following the manual, Zheng Ren adjusted the current and applied electrical stimulation to the renal sympathetic nerve.

However, Zheng Ren was dumbfounded.

That fused segment, after weak bioelectric current stimulation, the experimental subject showed no reaction at all.

Had the big pig trotter crashed? As soon as that thought popped up, Zheng Ren dismissed it.

Impossible!

If it weren't for that reason, then perhaps…… Zheng Ren froze for a moment, then began carefully observing the course of the renal sympathetic nerve.

Whether the experimental subject lived or died was no longer important.

This surgery was bound to fail. The earlier partial dissection had problems, and Zheng Ren quickly realized this.

As expected, Zheng Ren sped up the surgery; the experimental subject, due to stimulation of the renal sympathetic nerve, had increased blood pressure, suffered cerebral hemorrhage, and died immediately.

Meanwhile, Zheng Ren continued the partial dissection, starting from the origin of the renal sympathetic nerve and searching bit by bit, rather than going retrograde. This was more troublesome, requiring a larger dissection range, with danger increasing exponentially.

But Zheng Ren had no choice.

Under 20× magnification, the surgery was exhausting. But Zheng Ren didn't dare blink his eyes, fearing he might miss something.

After a long time, he finally finished dissecting the renal sympathetic nerve.

It turned out that everything before was completely wrong!

The fused segment of the renal artery and renal sympathetic nerve looks like that part of the nerve, but damn it, it's not! It's a piece of connective tissue. It just looks thick, following the shape of the renal sympathetic nerve, making it easy to mistake for the renal sympathetic nerve segment.

Meanwhile, the true renal sympathetic nerve lies buried underneath, almost fused with the outer layer of the blood vessel.

Zheng Ren let out a long breath; the surgery's difficulty increased further. But that didn't matter—having found the cause of repeated failures, what came next would be simple.

After all, with the surgical skill at this level, once the problem is found, there's nothing special about it; just follow the steps and it'll be done.

Zheng Ren began a new surgery.

Cut open, locate the renal artery stenosis segment, then directly sever the spot previously thought to be the renal sympathetic nerve; the experimental subject showed no reaction at all.

After layer-by-layer blunt dissection of connective tissue less than 1mm thick, Zheng Ren finally saw where the renal sympathetic nerve was located.

Under 20× magnification, all operations are magnified. He held his breath and focused, gradually freeing the renal sympathetic nerve.

This time the experimental subject didn't die, and its condition remained unchanged.

Looking at the freed sympathetic nerve, Zheng Ren knew this surgery was basically successful!

Next came the endovascular procedure.

Puncture, super-selective, stent insertion.

When the stent was opened, Zheng Ren's heartbeat seemed to stop.

The ECG monitor attached to the experimental subject showed steady numbers, with no major fluctuations.

As the stent fully opened, the experimental subject also showed no numbers indicating death after some time.

Zheng Ren didn't celebrate, but instead began washing, closing the abdomen.

After finishing the last stitch, he looked up.

Shou Bing completion degree——97%!
