The next day.

At ten past eight in the morning.

Zhao Heng arrived at Yanjing University early, using the information he reserved last night, he obtained a temporary student access card, entered the school, and found the large classroom where Professor Li Hongwei would give a public lecture later.

Finding a seat in the third row near the front, Zhao Heng sat down.

To be honest, this was the second time Zhao Heng returned to campus after graduating.

Previously, it was to Boya Medical College; this time it's Yanjing University. This Yanjing University felt quite different to Zhao Heng.

Compared to other universities, Yanjing University has a much stronger humanistic atmosphere.

The students here also seem to have a different state compared to those at other universities.

After all, it is the pinnacle of comprehensive universities!

The public lecture was scheduled to start at eight thirty, but even at eight ten, a lot of people had already arrived.

It seems that even though Professor Li Hongwei's lecture was about the frontier field of stem cell therapy research, there were still quite a few people interested at Yanjing University.

However, compared to the public lectures of professors from humanities disciplines, the number of attendees was noticeably less.

After all, the field of stem cell research is still too advanced and profound for university students.

Zhao Heng took out his laptop from his bag and got ready, as Professor Li Hongwei's lecture, though not about specific technologies, would definitely cover some forward-looking concepts, which would be quite enlightening for Zhao Heng.

Also, only by fully engaging with this course can he gain experience and skills from Professor Li Hongwei, which Zhao Heng had already verified before.

Just as Zhao Heng was getting ready to attentively listen to the lecture, a very familiar voice suddenly came from beside him: "Senior."

Zhao Heng turned his head to look; it was Shu Xin, the junior student who had somehow taken a seat beside him, looking at him with a cheerful smile.

"How come you're here?"

Seeing Shu Xin arrive, Zhao Heng was a bit surprised.

"I don't have classes today, so I came earlier. Besides, it's better to come now than wait until noon; we can go to the studio together later."

Shu Xin briefly explained.

After hearing Zhao Heng mention it yesterday, Shu Xin reserved a spot for the public lecture as soon as she got back and also arrived early this morning.

"This lecture will last until noon; won't you feel bored staying here?"

Zhao Heng looked at Shu Xin and asked.

Shu Xin's major is anesthesiology and is basically unrelated to stem cell therapy techniques in the medical field, so she probably wouldn't be interested in this public lecture.

"Not bored at all; how could it be boring sitting next to you, Senior?"

Shu Xin laughed lightly.

"Alright then, as long as you're happy."

Zhao Heng glanced at the sweet-tempered and refreshingly charming junior and said slowly.

"Mm-hm, mm-hm."

Shu Xin nodded repeatedly.

In no time, the students who came to attend the lecture walked in one by one, noticing Zhao Heng and Shu Xin sitting in the third row, drawing some sidelong glances.

After all, a handsome guy and a sweet girl; this kind of captivating combination is quite rare, at least pleasing to the eye.

However, after a glance, most of them didn't pay much attention, as Yanjing University, being a top-level comprehensive university in the country, naturally has plenty of talented handsome men and beautiful women!

Time quickly approached eight thirty, and right on time, Professor Li Hongwei walked in. Before that, the assistant had already set up the projector and microphone.

As Zhao Heng looked, Professor Li Hongwei appeared to be in his forties, wearing glasses, possessing a very scholarly aura, more like a poet or a literary figure rather than a life sciences professor.

"Welcome to this public lecture, everyone. Before class, I want to ask you all, is there anyone who understands stem cell therapy, especially somatic cell reprogramming?"

Professor Li Hongwei stood behind the lectern and spoke into the microphone.

His voice was resonant and magnetic, sounding very reassuring.

Asking questions before lecturing encourages students to listen with purpose, a common and effective teaching method. It shows Professor Li Hongwei's proficiency in research and that his teaching is quite good.

However, despite asking this question, he didn't expect any student to be able to answer.

As for stem cell therapy, any student related to medicine could roughly speak about it, but somatic cell reprogramming is currently the most cutting-edge research globally. Indeed, this is research he recently completed and published in the journal Cell.

To deliver a public lecture, one must first present unique expertise so attendees appreciate the value of the lecture.

Once Professor Li Hongwei mentioned this, the classroom fell silent. Upon hearing stem cell therapy, the students in attendance were eager to respond; those attending were science majors related to life sciences, naturally aware of this trending treatment method.

But when Professor Li Hongwei touched on somatic cell reprogramming, it was completely beyond their scope of knowledge.

After all, somatic cell reprogramming is a research project pursued by experts like Professor Li.

Seeing the classroom fall silent, Professor Li Hongwei continued with a smile to encourage them, "Does anyone want to answer? Don't be afraid of answering incorrectly, be bold in speaking."

The students in the classroom looked at each other, slightly shaking their heads, as it was beyond their knowledge scope, no one raised their hand to answer.

Seeing no one answer, Professor Li Hongwei smiled slightly, feeling a little disappointed and was about to start the lecture.

Just then, Zhao Heng suddenly raised his hand.

With that raise of hand, the entire large classroom's eyes turned to him.

Standing at the lectern, Professor Li Hongwei saw a student raise their hand, a hint of relief surfaced on his face, and he smiled happily, "The student who raised your hand, please share your understanding of somatic cell reprogramming. Don't be afraid to say something wrong, speak boldly."

Finally, someone raised their hand. Professor Li Hongwei was rather pleased.

Originally, stem cell research itself is quite advanced and complex; finding a kindred spirit is indeed a difficult task.

Especially among students, finding one who can comprehend his research.

Thus, Professor Li Hongwei eagerly anticipated Zhao Heng's response.

Meanwhile, other students in the large classroom were looking at Zhao Heng's somewhat unfamiliar handsome face, wondering which college he was from.

Never seen him before!

He does look quite handsome!

Standing up to answer Professor Li Hongwei's question, could he be an undercover expert!

That's what the students sitting in the large classroom were thinking.
