2369.2283 Envious? I have a set of backup organs.

At the end of May, the night here was still a bit chilly.

But I don't know if it's because we just came out of the hot springs or because we came out to relax, everyone's faces were flushed from drinking, and they all looked happy.

Zheng Ren looked at the scar on Feng Xu Hui's left thigh and walked over.

"Boss, you're finally back." Su Yun said with a smile, her black hair fluttering at her forehead, as if welcoming Zheng Ren.

"Hmm."

"Is the patient stable?"

"He's been sent to the hospital for admission." Zheng Ren sat beside Xie Yiren, habitually taking her hand, and recounted the whole process of going to People's Hospital.

"Guessing again means you're meddling." Su Yun said disdainfully, "It's as if the earth would stop turning without you."

"I saw it; if I can help, I'll help." Zheng Ren chuckled, then looked at Feng Xu Hui and asked, "Xiao Feng, is your scar-prone constitution innate?"

"It's fine; normally there isn't much of a reaction." Feng Xu Hui said.

"I see your thigh scar is serious; do you want to get rid of it?" Zheng Ren asked.

"No thanks, Chief Zheng." Feng Xu Hui said, "Doing another surgery would hurt a lot, and even with spindle excision and resuturing, a scar would inevitably remain."

"There's a new technique that might work here." Zheng Ren laughed while handing Xiao Yi Ren a dish, then said, "Once the technology matures in a few years, we can give it a try."

"A new technique?" Su Yun drained her cup, looked at Zheng Ren, and asked, "What kind of technique… don't tell me yet, let me guess."

Having to guess all this, there's no one else. Zheng Ren ignored Su Yun and instead whispered to Xie Yiren.

"I know, you're talking about that article in the journal *Biomaterials and Tissue Engineering* about 3D‑printed living skin with blood vessels, right?" Su Yun quickly recalled the relevant paper.

Zheng Ren was actually a bit surprised—Su Yun, who's always glued to her phone, somehow knows every latest tech news.

Though I suspect and don't understand, Zheng Ren has no habit of prying into people's privacy. Besides, Su Yun has a wide social circle; maybe a friend from some lab chatted with her about it.

Zheng Ren nodded and said, "Currently available 3D‑printed skin is like a band‑aid—it just promotes epidermal cell growth and eventually peels off. The recent research trend is to directly print skin that, once applied, can grow."

"Hmm, that's the future direction." Su Yun said, "The application of 3D printing in fine‑science fields will only become more widespread."

"Blood vessels? Do we need to anastomose them?" Feng Xu Hui asked, "If we have to do anastomosis, the difficulty would probably be huge."

"We won't." Zheng Ren said, "This technology has already entered the animal‑experiment stage. 3D‑printed skin transplanted into immunodeficient mice begins to communicate and connect with the mice's microvasculature, and after four weeks of implantation it successfully achieves perfusion."

"Biomaterials, Journal of Tissue Engineering and Regenerative Medicine, Tissue Engineering—these journals all have similar reports." Su Yun said, "Just keep an eye on it, like watching laparoscopy equipment twenty years ago. I'd guess that in about ten years, many of today's cutting‑edge technologies will truly be rolled out clinically."

"Hmm, maybe it'll happen soon. By the way, Indian researchers recently reported that they successfully used 3D bioprinting to print artificial skin with anatomical structure and biochemical properties similar to natural human skin, which could be widely used in cosmetics and skin‑drug testing."

"India, hehe." Su Yun chuckled, "Do you think it's reliable?"

"Who knows, but this is probably a preliminary product." Zheng Ren said, "Similar to… cosmetics? If Sister Lin is interested, she could go check it out."

"Be careful not to get scammed—there are the most fraudsters in finance. Dahungya‑type people are just small‑time swindlers who risk getting in to cheat a few melons and dates. Big swindlers are terrifying; losing family fortune is trivial, and many people scammed end up with ruined families, yet you still can't find fault." Su Yun said.

"Never mind that—actually, the primary application for 3D‑printed skin is definitely not cosmetics but burns." Zheng Ren said.

Su Yun chuckled, looked around, saw Lin Yuan seemed preoccupied and wasn't saying much, then continued the boss's words.

"Skin grafting is the first‑choice treatment for large wounds and burns, but when there isn't enough healthy skin to use, it becomes a headache. I remember back in 912 I met a pair of twins…" As she spoke, Su Yun looked at the older and younger Chu and laughed.

"What are you laughing at? Envious?" Chu Yan zhi said, "At the very least we have a set of backup organs; before 3D‑printed organs become usable, we'll definitely live longer than you."

"Hahaha." Su Yun burst out laughing; Chu Yan zhi's remark left him completely unable to rebut.

The backup‑organ thing is indeed true. In that case, one twin got a kidney transplant, the other a skin transplant, and the twins' advantages were fully shown. Those twins were so badly injured that, if it had been a single person, the chance of survival would not have been great.

Although not all twins can undergo organ transplantation, the inability to do so is actually a low‑probability event.

"How do you use 3D‑printed skin?" Feng Xu Hui was still pondering this.

"Through integrated imaging technology, we can use equipment to scan the wound, input the data into software, and thus tell the print head exactly which cells to deliver layer by layer to where.

The bioprinter will deposit cells directly onto the wound and replicate a layered skin structure, thereby accelerating the formation of normal skin structure and function." Su Yun explained.

"How about it, are you interested?" Zheng Ren chuckled as he looked at Feng Xu Hui and asked.

"I'm not just thinking—if the technology matures, I can become its agent. As the national general distributor, I could then follow Chief Zheng with peace of mind, traveling nationwide and worldwide." Feng Xu Hui laughed as he said.

"That's a route, but it's too far off. If you're thinking about that, you'd be better off pondering artificial lenses." Su Yun said, "Dragging the boss to do a thousand or eight hundred surgeries would directly overcome all the doubts and difficulties of artificial lenses."

"Artificial lenses already have national agents." Feng Xu Hui said with a hint of regret.

It seems he often pondered future ideas as well; Zheng Ren thought. Feng Xu Hui's entry point is excellent—he stands at the cutting edge of technology and lays things out from a high level. Twice the result for half the effort, and if we're just talking about making money, this is feasible.

But for now, leaning on Boss Zheng's thick thigh, there's absolutely no need to do these.

"Drink, drink." Su Yun raised her cup, glanced at Lao He, and said, "Older Chu, Younger Chu, you need to look after Teacher He. During this time, Teacher He has been imparting all his knowledge; if you don't let him drink well, can you really repay his painstaking efforts?"

"All right!" Chu Yanran and Chu Yan zhi gave a light smile, raised their cups in perfect unison, a beautiful yet startling sight, and said, "Teacher He, we offer you a cup."
