This question is quite professional, directly pointing to the core key technology, and it is the content of the latest issue of a top journal. Even researchers who closely follow international research developments find it difficult to answer such a question.

Dean Xia's heart instantly jumped to his throat, and his palms began to sweat. He knew that Zhang Lin, although he was a teaching secretary at the Institute, actually just managed the interns and trainees to do odd jobs, and now his true colors were about to be revealed!

He immediately got up, pretending to fetch the kettle: "Leader, the tea has gotten cold, I'll get some water for you. Xiao Zhang, go to the next room to get some tea leaves..."

"Not cold, it's just right." The leader waved his hand, his eyes blazing while looking at Zhang Lin, "No need to fetch tea leaves, this is good enough. Let Xiao Zhang finish, I'm very interested in this."

Zhang Lin was unfazed, calmly putting down the teacup, his posture straight, adopting a stance akin to a young scholar delivering a stable report. He cleared his throat and began:

"Leader, your question is very professional. The core advantage of this bionic nano-liposome delivery system is 'precision' and 'safety'."

"Oh? Elaborate on that." The leader leaned forward slightly, his interest growing.

"Traditional viral vectors, although they have high transfection efficiency, pose potential immunogenicity and insertion mutation risks, and their targeting for terminally differentiated neurons is not ideal. Physical injection, on the other hand, easily causes secondary injury, and the delivery scope is limited." Zhang Lin spoke eloquently, using the terminology quite fluently.

"And the new system, by modifying a specific transmembrane peptide and neuronal targeting ligand on the liposome surface, achieves efficient, specific targeting of neuronal cells in the injured area. It optimizes the lipid composition of liposomes, enabling efficient fusion with the mitochondrial membrane, directly 'delivering' functionally normal mitochondria into the cytoplasm of damaged cells, avoiding degradation by the endosome-lysosome pathway, significantly improving transplantation efficiency. As it is a non-viral vector, its biosafety is extremely high, with almost no risk of tumorigenicity."

Actually, Zhang Lin hadn't read this paper, but he spent so much time online that he would inevitably encounter discussions among others, and over time, knew a bit about everything.

This explanation was logically clear with well-defined points. Not only did it answer the question, but it also provided horizontal comparison, showing that he was a top expert in this field.

The leader nodded frequently, the admiration in his eyes growing stronger: "Good! Clear thinking and thorough understanding! So, with this research on animal models, how should you preset observational indicators, and what challenges might arise?"

Dean Xia was already stunned beside him, almost failing to hold the kettle steadily. He was incredulous as he looked at Zhang Lin, wondering when this kid had absorbed all this knowledge? Wasn't he always in the lab gossiping about "who's dating whom" and "who's recently close to whom"? Could it be that while spreading gossip, he accidentally absorbed and broadcast the technical difficulties discussed by top doctors and postdocs?

Zhang Lin remained composed, continuing to respond: "In the spinal cord injury rat model, we mainly evaluate through BBB scoring, footprint analysis, electrophysiological testing, and histological staining."

"As for challenges," Zhang Lin paused, showing just the right amount of "concern" expression, "I believe the biggest difficulty lies in ensuring the in vivo activity and long-term retention effect of transplanted mitochondria. Once isolated, mitochondria are relatively fragile, and after transplantation may be cleared by host cells. We are currently attempting to solve this issue through pre-treatment and the combined use of certain small molecular inhibitors."

"Brilliant!" The leader couldn't help but gently pat the sofa armrest, his face full of joy at having discovered a treasure. "Look! Old Xia, this is the talent from our Sanbo Research Institute! Solid theoretical foundation, well-versed in cutting-edge progress, and valuable for recognizing difficulties and challenges in research without being impetuous or evasive. Excellent! Very good!"

Dean Xia's facial muscles stiffened, forcing out a grimace worse than crying: "Yes... yes, Xiao Zhang... is quite... quite diligent in learning." In his mind, he grumbled: This darn loafer actually retorted flowingly, making it seem like he really is just a young and talented individual.

The leader got more and more enthusiastic and asked a series of questions in different directions, ranging from the ethical boundaries of gene editing technology to the application prospects of artificial intelligence in medical imaging diagnosis, and even the Spatial Orientation Gene Theory.

Zhang Lin seemed to activate the "super broadcast" mode, cleverly integrating and refining the discussions, debates, and even complaints from real top researchers overheard in various corners of online groups and the lab, then packaging them using confident and fluent language. He was like a human search engine — lacking originality but with astounding information reserves and retrieval speed.

Dean Xia tried several times to interrupt.

"Leader, it's getting late, look…"

"Xiao Zhang, is your phone ringing?"

"Zimo just sent a message saying there's something urgent in the patient ward?"

"Dr. Zhang, are you on duty today?"

Each time the leader dismissed it with ease, enjoying the conversation.

"No rush, no rush, let's chat a bit more."

Dean Xia was completely helpless, accompanying the leader like sitting on pins and needles, watching Zhang Lin carry the "young talent" persona further and further, while he himself got increasingly ensnared in the fear of "how to end once the truth is revealed."

"Listening to you is better than reading for ten years!" the leader finally commented sentimentally. "Xiao Zhang, you make me confident in your Institute, and even the young generation of researchers in our country! Neither only book-following, nor only the superiors, but only the reality. You have ideas, passion, imagination, and responsibility!"

He stood up, giving Zhang Lin's shoulder a friendly pat: "Keep up the good work! The future is yours, and I hope to see breakthrough results in your projects next time I visit."

Zhang Lin was so excited that his face flushed, straightening his chest, his voice bright: "Please rest assured, leader, I will work hard and not let down your expectations and the organization's training!"

The leader nodded his satisfaction and said to Dean Xia, "Old Xia, your Institute is truly teeming with concealed talent! I'm very pleased!"

Dean Xia could only force a laugh and agree: "The leader praises too much, we will definitely strive further."

The leader glanced at his watch; it was late, and he still had to go to Nandu Province Hall to inspect work, ending his trip to Sanbo Hospital.

Finally, the satisfied leader was sent off.

Once the office door closed, Dean Xia seemed drained of strength, collapsing onto the sofa, exhaling a long sigh, feeling like he had fought an incredibly tough battle.

Zhang Lin, still immersed in immense excitement and glory, rubbed his hands and approached Dean Xia to boast: "Dean, did I perform okay just now? Didn't I embarrass you?"

Dean Xia looked up, casting Zhang Lin a gaze filled with extreme complexity; it contained post-fear, helplessness, and an absurd mix of admiration?

He opened his mouth, wanting to scold him, but recalling his "fluent response" performance earlier, swallowed the words back. Finally, he weakly waved his hand:

"Get out! Quickly return to your patient ward! Keep today's matter to yourself! If Tang Shun and Yang Ping find out I secretly brought the leader inside, and caused such a scene, you're in trouble!"

Zhang Lin shrank his neck but couldn't hide the smugness on his face, responding with a cheerful "Yes, guaranteed to keep it secret! Dean Xia, you're not familiar with me — once I exit this door, today's matter will surely rot inside." Then he briskly slipped out of the office.

In the empty office, Dean Xia was solitary, reminiscing the thrilling hour and more earlier. He picked up the cup of now-cold tea, drinking it all. The bitter taste spread.

He murmured to himself: "Could this kid actually be an odd talent? Even the worst, Zhang Lin turned into an invaluable talent in the unknowing leader's eyes? This shows..."

Upon thinking this, Dean Xia's heart, which had been hanging all along, inexplicably calmed down, a smile appearing at the corners of his mouth.
