This is something utterly unthinkable during the Northern Song Dynasty; even the Emperor's family couldn't afford such luxury. (Note: Emperor Zhenzong of Song used a chair for defecation, with a wooden bucket underneath.)

Thinking of this.

Old Su couldn't help but sigh slightly:

Just as Xu Yun said.

There's still so much I need to learn.

During our previous casual chat, Xu Yun actually briefly analyzed my situation:

The skill I currently master the most is undoubtedly literacy; I can easily recognize most Chinese characters and understand their meaning.

In professional aspects.

Although I haven't undergone modern education personally, not even seeing a cafeteria auntie.

Still, my knowledge of mathematics and science from the Northern Song period isn't particularly outdated, especially since Xu Yun has taught me for a year.

Thus judging comprehensively.

My current level is roughly high school for physics, while math, chemistry, and biology are about middle school level.

Adaptability is indefinite, but mastering 21st-century lifestyle habits should be doable within one to two months.

Also, according to Xu Yun's introduction.

College physics generally requires four years of study before "graduation," after which one can either seek employment or choose to attend graduate school.

To have the capability to assist Xu Yun with research and development, one must have at least 'second-year graduate level' proficiency.

Therefore, Old Su quietly set a goal for himself:

Strive to elevate math, chemistry, and biology to university level within a year, and physics to second-year graduate level.

Should... not be difficult, right?

After all, when it comes to learning, I've truly never feared anyone.

Another half hour passed.

The bed delivery vendor arrived.

A few people worked together to move the wooden bed into Old Su's room.

Once the vendor left.

Old Su proactively expressed his desire to sit inside the room for a while; Xu Yun then found the CCTV film 'Huaxia General History' on a tablet for Old Su to start watching from Episode 98.

After doing this.

Xu Yun watched Old Su enter the room; then he returned to the bedroom and took out...

A USB drive.

This USB had quietly appeared in his pocket when he returned, and by pinching its sides, a light screen would appear in front of him:

[Artificial Intelligence - Beginner Version - Upgradable:]

[Growth-type artificial idiot, just plug the USB drive into the port for automatic activation, foolproof one-click operation because it is indeed a fool!]

"..."

Seeing this prompt, Xu Yun couldn't help but gently rub his temples.

A few seconds later.

He exhaled heavily.

Oh well.

Although he didn't have much hope for this artificial intelligence, it didn't hurt to try since it was a task reward.

With this mindset, Xu Yun plugged the USB into the computer port.

This computer was a custom-built machine configured through a friend, costing over four thousand RMB with moderate performance.

It could run games like PUBG and LOL, but not high-configuration ones like Elden Ring; mostly, it was for watching videos or work.

At this moment, the computer screen showed the desktop homepage, with a background of Tifa similarly dressed.

With the USB plugged in, the screen quickly turned into a gray speckled pattern, as if a TV with no signal.

Seeing this.

Xu Yun simply glanced at the port to ensure the USB was secure and patiently waited.

Although Halo often came up with some provocative words, it was reliable in terms of rewarding realization; program chaos was impossible.

Sure enough.

Over ten seconds later.

The screen flashed again, and at its center appeared...

A cat head.

This cat head wasn't 3D nor color images; how to put it...

If you were born in the 90s, you'd probably seen wristwatch-like toys called electronic pets.

Also known as "pet eggs" or electronic chickens.

The appearance of this cat head was extremely similar to early electronic pets:

A grey-white screen, rough digital dots, it actually looked clearer without glasses.

Beneath the cat head was an input field; Xu Yun tried shaking the mouse.

Yep, responsive.

Then he moved the mouse to the input field and typed a combination of Chinese-Japanese greeting using the keyboard:

Can you hear me?

Moments later.

Cat head:

"(¯﹃¯)...."

"...."

Xu Yun took a deep breath and continued typing:

"Hello?"

"(¯﹃¯)...."

"(,,･∀･)ﾉ゛hello?"

"(¯﹃¯)...."

"halamadrid?"

"(¯﹃¯)...."

Xu Yun laughed angrily and typed quickly:

"Is this the only expression you have?"

Cat head:

"（゜ρ゜）...."

Seeing this, Xu Yun slapped his forehead—Halo didn't deceive me; this thing is indeed an idiot!

He then tried entering commands such as play video, play music, and what is 1+1, only got (¯﹃¯) and （゜ρ゜） expressions as responses.

Yet as Xu Yun sighed.

The cat head suddenly shrank sharply, becoming a background process in the status bar at the bottom right of the screen.

Xu Yun was slightly dazed, then came to his senses and moved the mouse over the status bar icon.

Soon.

A prompt appeared:

[Automatically growing, current progress: 0.0000000000000000000000000000000001%]

One second later, the prompt refreshed again:

[Automatically growing, current progress: 0.0000000000000000000000000000000002%]

"Automatic growth?"

Seeing this prompt, a glimmer of consciousness flickered in Xu Yun's eyes.

Computers are complex in terms of functionality, but in nature, it probably relates to artificial intelligence in two ways:

One is electricity.

Two is information accessed online.
