"I heard you've been quite busy lately, developing software with others and doing research with Professor Li Hongwei."

Liu Ziang suddenly smiled and said.

"Senior, I also have to make a living, you know. If I don't do all these things, how can I support my family? Not to mention, I've got to at least save for the house down payment."

Upon hearing Liu Ziang's half-joking remark, Zhao Heng said indifferently.

Liu Ziang's family background must be quite good, otherwise, he couldn't have supported studying abroad for a Ph.D.

"True, but you really are something, junior. You've managed to whip up quite a career out of these short-term projects. Apart from these, I remember you're also running a video channel on Bilibili, right?"

Liu Ziang was also somewhat impressed by Zhao Heng's energy. Working at a top hospital like Eastern Hospital, a doctor's job is extremely stressful. To be able to juggle so many things under such high-pressure work conditions, Zhao Heng seemed to have superhuman stamina.

If there were a contest for the biggest workaholic at Eastern Hospital, if Zhao Heng claimed second place, no one would dare claim first.

"Why? Senior thinking about appearing on camera? I've actually been worrying about content for the latest episode. How about you do an episode?"

Zhao Heng quickly said upon hearing Liu Ziang.

Managing a video channel requires consistency, at the very least updating once a week.

If updates are delayed too long, you'll lose followers.

Currently, that's Zhao Heng's dilemma. It's clear his video update speed can't keep up.

"On camera? How many followers do you have now?"

Liu Ziang took a sip of coffee and asked.

"Just over three hundred thousand, I suppose."

Zhao Heng thought for a moment and said.

"That's quite a lot. You're not selling sex appeal or being suggestive, and to gain so many followers with serious medical education is already pretty impressive."

Liu Ziang seemed quite knowledgeable about the self-media market, or maybe he frequently browses Bilibili when he's free.

"After hitting three hundred thousand followers, growth has slowed down, and each video gets only fifty to sixty thousand views now."

Zhao Heng said with some frustration.

"That's already very good. Are you hoping to become a multi-million follower internet celebrity?"

Liu Ziang smiled and said.

In his view, Zhao Heng was being a bit humble. The self-media industry is complex and unpredictable, especially follower growth, which is quite mysterious.

Some people spend a lot of time and effort in this field but can't even get ten thousand views for their videos, with only a few thousand followers.

Yet, some video accounts, labeled as dance videos, gather millions of views with just a hint of suggestiveness, leaving those who create serious content bewildered!

"Who in the video account business doesn't want millions of followers? To be honest, I want that too, but there's a natural limitation in doing medical education. Having a million followers, I'd consider it quite an accomplishment."

Zhao Heng said realistically.

Although the number of followers in educational videos can't match those of big celebrities, the followers are quality ones, which is quite advantageous.

"How's the income from running your video channel?"

Liu Ziang asked with curiosity.

He also spends his free time browsing Bilibili, so he's quite curious about the income from running a video channel.

"Incomes vary by type. Those who repost videos earn less. Mine's alright, last month's income was over ten thousand."

Zhao Heng said.

"Hmm, as a side job, that's quite good. With your follower count and video views, you must have businesses approaching you, right?"

Liu Ziang asked again, intrigued.

Income from a video channel comes partly from views and clicks, along with incentives from the platform.

Another part comes from advertising contracts, commonly known as "eating the commercial rice."

"There are, but I haven't taken any."

Zhao Heng stated.

His video account is verified, and he joined as a medical professional, so he rejects all advertising deals.

"As a pure medical professional, you really shouldn't take commercial deals, it'd cause troubles for you."

Hearing Zhao Heng's rational response, Liu Ziang nodded appreciatively. Not everyone has the resolve to turn down easy money from business deals.

"After saying so much, how about appearing on camera, senior?"

Zhao Heng eagerly asked again. Liu Ziang is quite a handsome guy, a super genius, and extraordinarily articulate, making him well-suited for doing medical education on camera.

After all, it'd be wasteful not to utilize such a good resource at hand.

"I could appear, I've got free time lately, but what should I talk about?"

Liu Ziang thought for a moment and said.

He's the type who likes to try new things, but being in the doctor profession actually limits his expression.

"How about the changes in cognition due to brain damage? This topic hasn't been done before and might interest viewers."

Zhao Heng suggested after pondering a bit.

"Brain damage and cognition? That's an interesting idea, but it might be more engaging if we use visual tests to show changes in visual perception, don't you think?"

Zhao Heng's suggestion clearly piqued Liu Ziang's interest. Being a true genius, he quickly thought of an excellent idea.

"Yeah, that's a great idea, senior. I think we can use the opponent process theory of retinal imaging to create some images for visual cognition tests. This would be more intuitive. Plus, I haven't seen anyone on Bilibili doing this."

Zhao Heng pondered and added.

"You're talking about the opponent process hypothesis?"

Liu Ziang asked with interest.

The opponent process hypothesis suggests there are three pairs of pigments in the retina: red-green, blue-yellow, and black-white.

When one pigment in a pair stops working, the other starts working.

"Yes, we can create images based on the opponent process theory. That way, viewers watching the video will definitely be interested."

Zhao Heng said.

Lately, he observed that test-type videos are increasing on Bilibili, and each test video has significant views and saves.

It's a clear trend that audiences now prefer highly interactive videos, essentially, test videos offering higher viewer participation and stronger immersion.

"Alright, junior, you're just using me as a tool!"

Liu Ziang teased with a smile, but in his mind, he was already considering how to create such test images.

Perhaps this is what they call a front of indifference with hidden sincerity!
