Chapter 204: 0199 Upside-Down Teaching (1/5)

"Hurry up and change, take off my clothes." Su Yun glanced at the clothes Xie Yiren had sent to Zheng Ren via courier, unmoved by the famous brand, a bit impatient, saying: "Tomorrow I still need to send it to the dry cleaners. Right, Manager Feng, could you send it for me?"

"Um... okay." Feng Xu Hui replied instinctively.

Chief Zheng's assistant, who helps him with work, should also be able to gain favor, right?

But sometimes the relationship between Chief Zheng and his assistant seems rather cold, and this assistant is especially shameless, always mocking and sneering at Chief Zheng.

I hope I haven't messed up.

While Feng Xu Hui was thinking back and forth, Zheng Ren didn't go to change clothes; instead, he held the clothes and stared blankly.

"What are you thinking about?" Su Yun asked: "Even if it's the clothes Xie Yiren bought for you, you shouldn't be so sentimental. Hey, are you lovesick? Snap out of it!"

"I'm thinking about the patient's images," Zheng Ren replied.

"Go wash up and sleep; it's not like she's a beauty, what's there to think about? You'd be better off thinking about Xiao Yi Ren." Su Yun curled her lips in a sneer.

Zheng Ren held the clothes in his hand; before him seemed a patch of mist that, under some force, grew thinner—if he could find a certain key point, he could dispel the mist as if poking through paper.

But where is that key point…

The closer he got to the truth, the more confused Zheng Ren became. Clearly, a little more effort would do it, but he didn't know where to apply that effort.

Seeing Zheng Ren spacing out, Su Yun patted his right shoulder and said: "You…"

"Ah!" Zheng Ren suddenly shouted.

"What are you yelling for? You scared me." Su Yun instinctively jumped back—her reaction was lightning-fast. He quickly checked and confirmed he hadn't touched Zheng Ren's injured shoulder, then relaxed, only to flare up in anger, the hair on his forehead bristling.

"I know what to do now—I'm going to the CT room! Su Yun, contact Liang Boshi, then go to the Intervention Department ward and get the contrast-enhanced MRI films for bed 7-22." Zheng Ren arranged.

"It's already late, okay?" Su Yun was a bit impatient, but when Zheng Ren spoke, he usually just grumbled a little; when it was time to obey, he always fulfilled the duties of a "perfect" assistant.

"You go change first; I'll contact Xiao Liang." After Su Yun finished grumbling, he picked up the phone and left.

Zheng Ren finished changing clothes, Su Yun had also finished contacting Liang Boshi. Feng Xu Hui didn't dare be careless, following Zheng Ren like a little bug.

He made up his mind: as long as Zheng Ren didn't chase him away, he would never leave, staying until Zheng Ren needed to go back to sleep. He constantly summed up lessons learned, yet he could never keep up with Zheng Ren and Su Yun's pace.

Zheng Ren walked with light steps and arrived at the 64-slice CT room. Just as inspiration struck, the mist that had been before his eyes seemed ready to vanish at a snap of the fingers.

But Zheng Ren wasn't certain; he needed to compare the patient's 64-slice CT with the contrast-enhanced MRI.

Su Yun left midway, heading to the Intervention Department ward to fetch the patient's contrast-enhanced MRI films.

When Zheng Ren arrived, Liang Boshi had already been waiting a few minutes; seeing Zheng Ren approach, he hurried over two steps, his face full of admiration.

"Boss Zheng, today I owe you a lot." Liang Boshi's thanks came from the depths of his heart, full of sincerity.

"Huh?" Zheng Ren blinked, wondering if Liang Boshi was speaking to him.

Zheng Ren glanced back; aside from Feng Xu Hui following him, he saw no one else.

"I'm in the same cohort as Fang Lin; we usually get along well and hang out together. Hearing he got hurt today, I feel awful and don't know how to help. If it weren't for Yun Ge'er telling me you saved Fang Lin… I apologize for any earlier negligence and ask for your tolerance." Liang Boshi spoke earnestly; his attitude compared to this afternoon… this afternoon was also not bad, after all he was found by Su Yun. But his current fearful, reverent enthusiasm cannot be compared to that.

"It's nothing, you're being too polite." Zheng Ren waved his hand.

"The machine is ready for you; go ahead with your work, and if you need anything, just call me." Liang Boshi didn't add extra pleasantries; after speaking, he ushered Zheng Ren into the operating room, then sat with Feng Xu Hui in the chair behind Zheng Ren, waiting silently.

Zheng Ren wasn't polite either; among tech people, talking too much feels distant.

Skillfully, he entered the patient's case number into the machine, found the 64-slice CT enhanced images he had been studying, and examined them closely once more.

Feng Xu Hui couldn't understand, thinking Zheng Ren was reading faces. But he looked very professional, giving a sense of reassurance that belied his age.

"Here are the films you wanted." Not long after, Su Yun rushed back, holding a large stack of films, and slapped them down onto the table before the viewbox.

Zheng Ren ignored Su Yun's actions; in his eyes, only the contrast-enhanced MRI films existed. As for Su Yun… she didn't exist at all.

He took out the contrast-enhanced MRI film and hung it on the viewer.

Comparing it with the 64-slice CT on the machine, he was extremely focused.

Su Yun lowered her head, fiddling with her phone, secretly took a photo and posted it in the group.

Feng Xu Hui didn't know what Zheng Ren was studying, found it boring, but he gritted his teeth and persisted.

This time, no matter what, he couldn't leave—this was his most important job.

After comparing the CT and dual-enhanced MRI images, the two master-level skills cross-referenced, and his previously vague understanding gradually became clear.

That layer of mist was like a windowpane—just a poke and it broke.

After pondering for half an hour, Zheng Ren already had a plan.

He began operating the machine, performing a retrograde 64-slice three-dimensional reconstruction.

The patient had over a hundred liver nodules; Zheng Ren didn't do them all, because doing so would involve a huge workload that might not be finished by tomorrow morning.

Zheng Ren spent nearly two hours selecting nine of the nodules for three-dimensional reconstruction. After excluding one, he confirmed the remaining eight were malignant tumors.

That must be it. After Zheng Ren finished everything and pressed the print button, he finally felt utterly exhausted.

"Boss Zheng, you're done." Liang Boshi said from behind.

"Mm, done."

"How did you pick these cirrhotic nodules as targets? On the CT they all look the same." Liang Boshi had been observing Zheng Ren.

While Zheng Ren was reviewing the films and doing the reconstruction, Liang Boshi asked a few friends and learned the details of the rescue of Fang Lin.

If it weren't for this Boss Zheng, I'd probably be going to the funeral home to see Fang Lin now.

After knowing all this, Liang Boshi genuinely wanted to help Zheng Ren with something.

But…

He didn't even know what Zheng Ren was doing, let alone how to help.

Still, he had some basic knowledge and could see that Zheng Ren's selection of several lesion points between tumor and cirrhotic nodules for three-dimensional reconstruction was targeted and purposeful.

"Do you understand?" Zheng Ren asked.

Su Yun pursed her lips; only Zheng Ren would speak so bluntly, and surviving this long without getting beaten is already no small feat.

"I don't get some parts here—why, after comparing with the MRI, did you decide to do a retrograde three-dimensional reconstruction?" Liang Boshi, who didn't have as many thoughts as Su Yun, had wanted to ask earlier but feared disturbing Zheng Ren.

"Oh, I see." Zheng Ren walked up to the viewer, pointed at a lesion with his finger, and began to explain.

Starting from the arterial phase of the nuclear magnetic resonance contrast, each phase was compared with the 64-slice CT; Zheng Ren made the subtle differences clear. Which areas need attention, which show abnormal enhancement, which need CT, and which need nuclear magnetic resonance.

Liang Boshi nodded at times, and was confused at times.

But Zheng Ren's explanation was clearer, and some difficult points were easily resolved when mentioned.

Liang Boshi nodded repeatedly, finally had an epiphany, and looked delighted.

Su Yun, meanwhile, raised her head from behind and looked at Zheng Ren's presented images with a rare serious gaze.

Feng Xu Hui gradually became confused again.

You must know, this is Di Du, not Hai Cheng.

How could Zheng Ren, the inpatient chief from Haicheng Shi Yiyuan, lecture the doctors of Di Du like a professor?

Shouldn't it be the doctors of Di Du speaking at length, with the small inpatient chief from Hai Cheng nodding frequently? That would be right, wouldn't it?

How come things are reversed today?

Could it be that I was too tense today, leading to an illusion?

In such a loving scene, Feng Xu Hui remained dazed and uncomprehending until Zheng Renhe and Liang Boshi said goodbye.

Liang Boshi, full of admiration, saw them to the gate before Su Yun rudely sent him back.
