Chapter 1558: 1510: One More Set of Numbers Than Cartesian Coordinates

"Tch." Director Chu whispered a rebuke.

"Hehe, don't believe me? Let's bet." Director Kong felt a bit lighter inside; being able to vent dissatisfaction is good, otherwise keeping all the unhappiness bottled up just accumulates until a big explosion.

This is the hidden danger in Zheng Lao Ban's work.

I myself brought the young people here, helped them onto the horse, and still have to see them off a bit further. Well, look at this old man's awareness.

Director Kong thought to himself.

"What's there that you can't do? You're just talking nonsense." Director Chu said disdainfully.

"Old Chu, don't look at Zheng Lao Ban with the same eyes you use for others." Director Kong muttered, "Manager Song Ying, you definitely know his background better than I do. What's your current attitude toward Zheng Lao Ban?"

"That's unrelated." Director Chu waved his hand, annoyed.

"Zheng Lao Ban is a visiting professor at Mayo Clinic." Director Kong said with a smile.

Uh... Director Chu lost his spirit.

It's not blind admiration of foreigners; although 912 is a domestic giant, it truly can't compare to Mayo Clinic.

"Let me tell you a piece of gossip, don't tell anyone else." Director Kong laughed.

"How?"

"I'm not saying it's about you; Zheng Lao Ban still respects us old-timers."

"What exactly is going on?" Director Chu's curiosity was successfully hooked.

"A few days ago Zheng Lao Ban went to Xianggang for surgery; a doctor kept pointing and criticizing, got slapped into the wall. He really was slapped into the wall—Zheng Lao Ban's physique is no worse than special forces." Director Kong whispered: "During earthquake relief, they went into the Sharp Blade Squad."

"Did he really strike?" Director Chu worried, "Won't he get sued?"

"Sued? That side actually had the idea; the three big lawyers of Xianggang stepped forward, directly charging that doctor with endangering others' safety."

"……"

Director Chu was speechless.

Is this bullying with power? It doesn't look like it.

He wanted to ask carefully what exactly was happening. This is a big piece of gossip; if not clarified, he'd feel uneasy.

But now Vice President Yuan and Director Ye are present, so it's not good to ask too much.

"Just watch closely; don't stay clueless." Director Kong gave kindly advice.

"I know." Director Chu said, his eyes fixed on Zheng Renhe sitting outside with Su Yun.

He still felt a bit unwilling to accept.

But turning against Zheng Lao Ban like that—such a foolish act—Director Chu, this old slickster, would absolutely not make that mistake.

How many times a year can Vice President Yuan go down to the clinic? In just one or two months, his visits have become noticeably frequent.

This time he said he was accompanying Old Li, but Director Chu knew full well that Vice President Yuan was surely here to see how Zheng Lao Ban makes diagnoses.

He stood silently to the side, watching Su Yun adjust the machine before the operating table.

Her technique is skilled, not inferior to mine……

Old Li took off his clothes and lay on the CT table; the lead door closed, and the CT machine emitted a low rumble.

Su Yun clicked start, and the machine began scanning Old Li's thoracic spine.

Zheng Ren stood inside wearing lead clothing, waiting silently.

1'12", the scan ended.

Su Yun placed both hands on the keyboard, and a clacking sound rang out continuously.

It sounded like playing the piano—at first a bit monotonous and dull. But after a few seconds, the clacking seemed to carry some kind of magic, plucking Director Chu's heartstrings.

"Doctor Su's operational level is very high." Director Chu and Director Kong whispered.

"Zheng Lao Ban's level is even higher." Director Kong said.

Director Chu recalled that a few days ago Zheng Lao Ban came for a CT, constantly suspecting a thoracic spine issue. Back then I seemed to have judged it as nothing and just walked away.

Is the level high?

I couldn't see it, and he also didn't think Old Li's thoracic spine had latent metastasis.

Even if there were metastatic lesions, even a PETCT couldn't detect them; fundamentally, you couldn't obtain pathological tissue via puncture.

Zheng Lao Ban is getting full of himself, but stumbling a little here is better than being slapped in the face outside.

Director Chu thought to himself.

At the same time, Zheng Ren in the CT room began disinfecting Old Li and laying down a sterile sheet.

Although it's a minor surgery in a contaminated environment, Zheng Ren remained meticulous; combined with his honest, simple face, he looked like a junior clinical doctor.

"12, 22, 21, 5.5." Su Yun opened the mic and reported a set of values.

Through the lead glass, one could see Zheng Ren beginning to insert the needle.

"Continue, 22, 34, 1, 6.1."

"What is this?" Director Chu looked bewildered.

He saw Su Yun quickly perform a 3D reconstruction with the CT machine, then start speaking some numbers, guessing they might be coordinates, but he'd never seen this kind of operation.

"Looks like a three-dimensional Cartesian coordinate system? Why is there another set of numbers after it?" Director Kong also frowned.

"Have you seen Zheng Lao Ban use it?"

"No. Before, when I saw Zheng Lao Ban teaching surgery, he used only two-dimensional coordinates, but it sounded like this."

"……"

"Su Yun has become Zheng Lao Ban's eyes, so we shouldn't mess around." Director Kong said.

He saw Su Yun composed and unhurried, Zheng Ren operating in the CT room calm and relaxed, his heart not tense.

Zheng Lao Ban felt it could be done, so it definitely could.

After several rounds of reporting numbers, the CT images kept scanning, and Director Chu also began to see a clue.

Just as Director Kong said, it should be a three-dimensional coordinate system. Each time Su Yun reported the numbers, the puncture needle in Zheng Lao Ban's hand reached the position, made a slight angle adjustment, and then continued forward.

Instead of the usual operation where a needle is blindly driven all the way through.

Director Chu doesn't know what's good about this operation method, but it is definitely a very complex and tedious operation method.

"Good, we're already approaching the position." Su Yun, like a race car's navigator, reported the position while chattering with Zheng Ren.

"22, 22, 32, 2.2."

"Once more, we can insert the needle." Su Yun kept the mic on, constantly communicating with Zheng Ren.

Meanwhile, Zheng Ren inside was like a wooden man, silent. He simply sent the puncture needle to the designated location based on the data Su Yun provided.

His manipulation was so subtle that hardly any movement could be seen from outside.

Only the refreshed CT images each time could show the puncture needle continually advancing.

"Good, this is it, enough." Su Yun made a victory gesture toward the lead glass.

Zheng Ren pulled the trigger in his hand and immediately withdrew the puncture needle.

His movement was very careful; Su Yun immediately opened the induction lead door and began handling the follow-up matters.

Meanwhile, Zheng Ren carefully unloaded the puncture gun, took the puncture needle, and handed it to Wu Hang, Manager Wu.

"Be careful." Zheng Ren said.

"I know." Wu Hang had already gotten into position, carefully taking the tissue that was completely invisible on the puncture needle.

The puncture needle was clean, with not a speck of blood or bodily tissue; Director Chu walked over and asked in surprise, "What is this for?"

"To take a pathological specimen." Wu Hang said.

"Where is the specimen?" Director Chu looked again twice but still couldn't find the pathological tissue specimen.

Normally, the tissue specimen extracted by the puncture needle is filamentous. But…
