Chen Qiuhua, completely baffled, hurriedly walked down from the observation deck, to the preparation room beside the operating room, and found Lin Jie changing into surgical scrubs. Next to him was a young woman, holding a few images and medical records for Lin Jie to quickly review.

Seeing this situation, he didn't dare to disturb Lin Jie and called over a young male doctor standing nearby who had already changed into his surgical attire, and quietly asked, "What's going on? Wasn't Dr. Xia the originally scheduled main surgeon?"

The male doctor stifled a laugh and lowered his voice, "Apparently, Dr. Xia had a seafood feast last night at the invitation of an old friend from Binhai and ended up with an upset stomach!"

"Earlier, before entering the operating room, Dr. Xia said he still felt a bit unwell. Out of responsibility, he decided to forgo this surgery."

Chen Qiuhua, somewhat understanding, gently nodded!

Doctors are also human; they eat grains and can get sick too.

This operation would last more than ten hours and was quite complex. If the chief surgeon couldn't concentrate or lacked stamina, a medical accident could easily occur.

"Then how did the patient agree to have Dr. Lin as the main surgeon? Weren't they always refusing before?"

The male doctor scoffed, saying, "He has no choice. All the doctors capable of performing this surgery at the Affiliated Hospital today were already scheduled for surgeries. Only the teacher still had time to take over..."

"The patient's condition is also quite urgent, with multiple aortic aneurysms that could rupture at any moment. Waiting another day means another day of life-threatening risk."

"Under such circumstances, he and the patient's family could only agree to let the teacher be the main surgeon."

"Hmph, truly a lucky fellow."

Chen Qiuhua agreed, "Hmm, indeed a lucky fellow..."

Just then, on the crowded observation deck, a buzz of conversation erupted.

Everyone suddenly realized that Xia Kaige, who was supposed to be in the operating room, was instead dressed in casual clothes and had come to the observation deck accompanied by several people.

Facing the puzzled gazes of everyone, Xia Kaige said loudly, "I suddenly felt unwell, so this surgery is being taken over by Dr. Lin Jie. If there are no other surprises, my surgery will be scheduled for tomorrow."

After saying this, he walked straight to the front row of the observation deck.

There was a perfect viewing spot originally reserved for Lin Jie but now taken by Xia Kaige. The few people who came with him were worse off, having to stand instead.

"Xia Yu, Xia Yu!"

Xia Yu looked in response to the call and saw Huo Guangheng standing up, pointing to an empty seat beside him and saying, "There's a spot here, come and sit!"

Xia Yu hesitated for a moment and considered the length of this surgery, then squeezed over.

After listening to Xia Kaige's detailed explanation, Ren Maoshi, sitting behind him, apologized in frustration, "Dr. Xia, I'm really sorry. Later, I'll pursue responsibility with that big hotel for daring to serve us unfresh seafood."

Xia Kaige said nonchalantly, "No need! It's probably because I haven't eaten seafood in a long time, causing some digestive discomfort."

He laughed lightly, "Although it was sudden, the outcome now is still quite a happy one!"

Ren Maoshi asked puzzled, "Dr. Xia, what do you mean by that?"

Xia Kaige pointed to the operating room below and smiled, "Without my unexpected situation, I assume no patient would choose Dr. Lin as their main surgeon in a short time."

"I don't have that much free time to stay in Binhai waiting for an observation opportunity."

Ren Maoshi chuckled and said without true feeling, "Indeed, indeed..."

At 9:10, Lin Jie, Chen Qiuhua, Tian Xiangyu, and Lu Xiaoyu entered the operating room...

The moment Lin Jie picked up the scalpel, everyone in the area, including Xia Kaige and Ren Maoshi, narrowed their eyes and focused their gaze on him without moving it away.

As they say, amateurs watch the fun, experts watch the technique!

At the level of Xia Kaige and Ren Maoshi, within their professional field, just a simple action could reveal a lot.

Particularly when Lin Jie grasped the scalpel, his entire presence seemed different.

He suddenly seemed much taller, with a kind of domineering and towering aura about him.

Watching Lin Jie's steady hand, without a hint of hesitation, make a long incision on the patient's left thoracic side, Xia Kaige couldn't help but nod and say, "This Dr. Lin is indeed worthy of his reputation..."

He couldn't resist turning his head towards Xia Yu's seat.

He saw her staring intently at the operating room below, seemingly very focused on observing and learning, and for the first time, Xia Kaige felt a twinge of regret.

For so many years, Xia Kaige had kept a close eye on Xia Yu's studies, giving guidance whenever he was free.

He thought to himself that maybe Xia Yu really needed advice from another brilliant teacher to broaden her horizons and thinking...

Huo Guangheng gently nudged Xia Yu and quietly asked, "What do you think, how's Lin's technique?"

"Ah... oh, very good, very impressive!"

Xia Yu, a bit distracted, gave a perfunctory answer, glanced at Gao Yanhong and Guo Peng seated on Huo Guangheng's other side, and softly asked, "Who's the trainee replacing me, didn't she come?"

"It's He Yimin, a famous figure from our First Military Medical University... she didn't come today!"

"It's actually her?"

Xia Yu was somewhat puzzled and said, "Even though her theoretical scores are better than mine, her practical skills and internship grades are really lacking!"

"How could the leadership let her replace me?"

Huo Guangheng said indifferently, "We still don't know why the leadership let her replace you. However, Dr. Lin's assessment of her is extremely high!"

"To be honest, the teacher tailored a reading list for each of us based on our strengths. He Yimin's list includes nearly a hundred books! Moreover, she was required to finish them within a year."

"She calculated, excluding the twenty or so books she had previously read, she needed to finish one book every five days, leaving no time to waste. As a result, she didn't come to observe this surgery!"

Huo Guangheng smiled brightly and said, "If she knew that the lead surgeon for this operation suddenly changed to the teacher, she would definitely regret it immensely."

"You keep calling him teacher, does it mean he has completely gained your approval?" Xia Yu asked with a tone of displeasure.

Huo Guangheng restrained his smile and said, "Xia Yu, you have good grades, a good family background, you're good-looking, you study hard, one could say you're outstanding in every aspect. We all know you have a lot of pride in your heart."

"But this time, I personally think you made a mistake!"

"Dr. Lin's talent is indisputable, even more outstanding than the rumors suggest!"

He pointed to the operating room below and praised, "This surgery is evidence! Look how Dr. Lin uses the scalpel with such ease and skill, like flowing water, filled with an enchanting charm!"

"I have observed surgeries by several surgical experts, and none has ever given me this feeling."

"This is the beauty of surgery!"

"Such a beautiful surgery will surely result in a beautifully perfect outcome!"

Xia Yu snorted coldly and said, "He's become your muse, so naturally, everything is exceptionally good."

Huo Guangheng chuckled without saying more, intently observing Lin Jie's surgical movements!

At this moment, Lin Jie had already taken an artificial blood vessel, preparing to replace a problematic section of the aorta.

The raw materials for making artificial blood vessels primarily include polyester, polytetrafluoroethylene, polyurethane, and natural silk.

Currently, the mainstream material for artificial blood vessels is polyurethane.

Artificial blood vessels made from this material cause mild tissue reactions after being implanted into the body, allowing human tissue to quickly form new inner and outer membranes, making thrombosis less likely, and having a satisfactory long-term patency rate.

However, artificial blood vessels are still foreign objects to the human body.

They will still stimulate a rejection response from blood vessels and affect the blood's coagulation function, making blood clotting and thrombosis formation more likely.

Therefore, patients with implanted artificial blood vessels need to take antiplatelet and anticoagulant medications long-term.

Thanks to the emergence of biological 3D printers, medical experts are researching ways to incorporate human cells into the raw materials in hopes of creating artificial blood vessels or organs that do not trigger rejection.

However, this research has yet to make groundbreaking achievements.

The main surgical challenge of the thoracoabdominal aortic replacement lies in the anastomosis of the artificial blood vessel with the artery and its branches.

This particular surgery involves at least six or seven anastomosis points.

Because these are arterial anastomoses, the blood pressure is high, requiring extremely high precision in anastomosis.

Among them, the anastomosis of intercostal arteries has special requirements that must be completed within an hour to ensure the patient doesn't suffer paraplegia due to prolonged spinal cord ischemia.

Lin Jie's surgical movements for anastomosing the arteries were completed inside the patient's body, obstructing the view of the onlookers. Moreover, due to the nature of this fine surgery, even without visual restrictions, it would be hard to see clearly.

However, there are several high-definition cameras above the operating table!

These cameras capture the surgical movements, which are then processed and enlarged, being clearly displayed on a large screen above the observation deck.

Everyone stretched their necks, eyes unblinking, staring at the big screen, watching the special silk thread woven back and forth across the anastomosed blood vessel walls under Lin Jie's deft hands...

Forty-some minutes later, Lin Jie successfully completed the anastomosis of the first blood vessel and began the next...

At this moment, unexpectedly, Xia Kaige stood up, instantly drawing the attention of many.

Xia Kaige took a deep breath, looking down at Lin Jie, who was calm and focused as ever in performing the surgery, and said deeply, "In this surgery, the techniques and methods for anastomosing major blood vessels are fairly similar."

"After observing this anastomosis, one can confirm Dr. Lin's surgical skills."

He paused for a moment and continued, "So far, Dr. Lin's performance in this surgery has been impeccable, with vascular anastomosis techniques being perfect and exemplary!"

"I..."

After another pause, Xia Kaige said, "I concede this surgical competition, acknowledging my inferiority! There's no need for everyone to waste time coming to observe my surgery tomorrow!"

Having said that, he walked off the observation deck briskly.
