From now on, it's just a matter of slowly digesting until you become an authority, and then try to step into the 'expert level'.

This world is basically about learning, learning, and learning.

All about the scientific theories and knowledge.

It's also a 'professional gap filling' for the things I've never learned before.

I focused too much on medicine and martial arts, which made my overall capabilities somewhat biased.

But now it's much better.

At least when I see something, I won't be completely clueless.

Thinking to himself.

Zhang Feng calculated the time, in another two hours he would return.

So let's take one last stroll.

Clap—

Zhang Feng stood up from the sofa and instantly arrived in front of the floor-to-ceiling window.

The next second, the window opened, not the imagined strong high-altitude wind, but a gentle warm breeze.

Then, under the floor-to-ceiling window, a large piece of magnetic alloy slowly extended, with a streamlined flying car on top.

Its body was entirely sky blue, emitting a soft glow in the morning sunlight.

On the side of the car, there was also the flamboyant calligraphy of 'Spirit Stone Technology'.

At the same time.

When flying cars passed by, their owners looked on with envy and amazement.

"Wow! Limited edition worldwide! I recall there is only one in the entire world, in the hands of a legendary elder..."

"Spirit Stone Technology? Is it Spirit Stone Technology?! It's Zhang Feng!"

"Bro! Quickly switch to autopilot, look over there, that elder is Zhang Feng! He was evaluated alongside Academician Chen as the dual hearts of civilization! I've read about him in the news!"

"Is it Professor Zhang? He hasn't appeared in public for so long, I didn't expect he was living in this building, which looks so ordinary."

"I guess after seeing him, he won't be living here anymore."

The appearance of the car caused a minor sensation in the sky around this area.

Some cars even opened up their side covers, revealing a photographic device.

Zhang Feng ignored them, got into the car.

"Go to the nearest mechanical platform."

He instructed the car's intelligent system and picked up the computer beside him.

Whoosh—

After Zhang Feng gave the command, unlike other cars that moved left, right, forward, or backward, or made slight adjustments in height,

It instead extended tail fins and the Z1 focusing chip from below both side doors, and then flew straight upward.

Zhang Feng completely ignored the vertical movement, still looking at the computer in his hand.

Most of the news in it was about the plan for lunar colonization.

Some people even began selling 'conceptual lunar houses'.

But the lunar colonization plan has not been realized yet.

Problems with radiation protection, living environment, psychological issues, and food supply, etc., have not been effectively solved.

Chen Genius did not have the time to solve them.

...

Over ten minutes later, after an exchange request with the intelligent system and the official route.

Plus Zhang Feng's signature.

At this moment.

Twenty kilometers high in the sky.

Whoosh~

The cold strong wind howled.

Wearing a protective suit, Zhang Feng got out of the car and stepped onto this 'steel structure'.

Looking as far as the eye could see, it was a steel jungle stretching over several kilometers in area, entirely constructed with superconductors and some special aerospace materials mixed in.

The top of these materials was densely packed with Z1 batteries.

The base frame of this steel jungle was rooted deep in the distant city below.

Additionally, on this steel structure, there were cube-shaped containers-like blocks, which were power boxes conceptualized by Chen Genius.

Their computing power is three times that of a small building in reality and supports full-function computing.

Their network is distributed over superconductors, achieving uninterrupted signal operation.

And their cost is only a tenth of that of a small building.

However, Zhang Feng, being proficient in electrical and materials science, could also dismantle some to provide computing power for his small building.

Because although these boxes are good, they are not specialized.

In reality, only specialization is needed at the moment.

He could single-handedly dictate most things.

"Academician Zhang..."

As Zhang Feng observed these, several specially made aviation flying cars approached from afar.

Additionally, behind them, several fighter jets patrolled overhead with the purpose of ensuring his safety.

"Hmm." Zhang Feng slightly nodded at them, then looked down.

In his view, under the cover of the mechanical platform, the local buildings had already grown to a kilometer in height.

And they could enjoy computing power from the power boxes.

It was compensation of sorts.

After all, their city had been occupied.

They surely needed a place to live.

The 'hive' below the steel platform was a pretty good one.

Even the quantum equipment in their homes shared computing power from the power boxes.

Or rather, a steel platform was a 'unified computing power machine' for a city.

This was Chen Genius's idea, and he even thought of connecting the entire globe.

Turning the entire planet into a supercomputing machine with unlimited energy.

Zhang Feng, through this, also had ideas.

In reality, the infrastructure of the steel structure could indeed be constructed.

His idea was good.

However, regarding the boxes, Zhang Feng wanted to replace them with 'single-function' small buildings.

That way, others couldn't steal his network, but he could use theirs.

Of course, appropriate compensation would be provided when the time comes.

As for this, just leave it to Old Liu and the others to figure out.

After seeing all this.

Surrounded by a group of people and a few fighter jets for protection, Zhang Feng came to the front of a box.

With authorization, Zhang Feng handed over his laptop, using a superconductor as a connection line, quickly receiving the latest Spirit Stone program data.

Unfortunately, there was no breakthrough.

20% optimization was currently the limit.

Expressionless, Zhang Feng put away the laptop, then looked at the cars, people, and aircraft around him, speaking through the communication device inside the protective suit,

"You're dismissed."

"Professor Zhang..." The guards didn't retreat, but instead expressed concern, "You're of such advanced age, if there's any information you need, let us collect it for you.

Please take care of your health; you are the remaining fruit of human science, everyone is worried about you."

"Hmm... go back."

...

An hour later.

In a privately marked top-secret global memorial park.

Zhang Feng gazed at Chen Genius's grave,

"Actually, if you were still here, I think the mechanical platform could be raised another ten thousand meters or so, with more optimized structural solutions.

You told me before that twenty kilometers is not the limit of human wisdom.

The space far above us is just the beginning.

Including the dreamed-up lunar colonization plans, if you were around, perhaps they might have materialized in the coming years."

"But now I'm all that's left, I've become the remaining fruit."

"Fifteen years ago, when you left,

the entire world awaited me to bring forth new research solutions, everyone was waiting for me.

I could only quietly retreat, continue tinkering with my martial arts, teach students, and examine the connections."

Zhang Feng shook his head at this point, "Forget it, no more talking, time's up."

Zhang Feng placed a flower before his grave,

"Old friend, I'm leaving."
