Ye Feng's understanding of the internal structure of a computer was still based on a video he had seen in his previous life.

A gamer actually managed to build a simple computer using the raw materials in a blocky game.

What he needs to do now is to use celestial materials to make this process a billion times more complex!

Time flew by, and only when a wisp of thought Ye Feng had left outside reminded him that the three days were almost up did he suddenly snap out of his daze.

It's been eight hundred years already?

Indeed, time seems to stand still in the world of cultivation!

The first thing Ye Feng did upon waking up was to see the trading point and curse under his breath.

"Damn... over two thousand!"

That's a real splurge.

Looking at the small box in his hand, about an inch long, two inches wide, and half an inch high, Ye Feng couldn't help but feel a pang of heartache.

This thing cost a total of about 20 to 50 billion.

Ye Feng's trading volume fell below the trillion mark again, reaching 860 billion.

One hundred million is equivalent to one immortal essence stone...

This "spiritual brain" actually cost over two thousand five hundred.

This is still the cost of materials!

Ye Feng glanced at his weapon-refining level, which had unknowingly advanced to level nine, and could only console himself with a thought.

"At least, it saved a lot of money on upgrades..."

To be precise, the crafting of a spiritual brain can be accomplished by a level four weapon refiner.

The difficulty lies in melting the immortal materials and concentrating on meticulously crafting the chip's interconnectivity day after day.

The code has now been fully entered, allowing literate individuals to edit the commands themselves.

Additional manifestations and telepathic communication have been added...

Ye Feng had originally planned to add a few more programs, but now he thought it best to leave the rest to Ma Qiling to try!

Perhaps she can use it from a perspective that Ye Feng hadn't considered...

The "spiritual brain" was about half the size of a portable hard drive. Ye Feng grasped it, and his magical power surged forth.

A short while later,

"Brain 1.0, it's a pleasure to serve you!"

For a moment, Ye Feng almost thought it was the system speaking...

This is not a spirit, but a system setting.

The voices in the system are also randomized. If the user is a little late in recognizing the owner, the voice will change to a different one.

Could it be that the system is also a "computer"?

Ye Feng looked at the "spiritual brain" in his hand and couldn't help but shake his head.

Everyone in the world knows that

The system exists without logic; it comes into existence from nothing, creates space, and requires strange and unusual energy.

If the "spiritual brain" is also a system, it can probably only be used by primitive people. For them, evolving into humans is just an intermediate goal.

The energy of a single immortal stone could last for several lifetimes...

Ye Feng chuckled self-deprecatingly, casually switched the voice on his spiritual brain to a pleasant female voice, and then vanished from the cultivation space.

Nearly eight hundred years had passed inside Ye Feng's cultivation space, but less than three days had passed outside.

When he appeared,

Xiao Xuan was still talking to Qin Rou, but the two seemed much more familiar with each other than before.

Ma Qiling was still busy, but it seemed the abacus was overloaded, making them even busier...

"Ma Qiling, come here!"

At Ye Feng's call, even if he was busy, he had to come and reply first.

"This thing... is yours!"

"This is?"

Ma Qiling looked at the small cube in Ye Feng's hand, somewhat puzzled.

Although she didn't understand why, the shape and lines of the cube, as well as the data flashing on it from time to time, deeply attracted her attention.

"Smart Brain!"

"I'm here! Brain 1.0, happy to serve you!"

Upon hearing the voice from the spiritual brain, Ma Qiling's eyes shone even brighter...

"This...is not a spirit!"

Ye Feng did not answer, but directly issued the command.

"Record Ma Qiling's breathing data and grant her Level 2 access!"

"OK!"

An invisible ray of light swept over Ma Qiling, and in less than a moment, the spiritual brain completely recorded Ma Qiling's features.

"Level 2 access user, Ma Qiling! Brain 1.0 is happy to serve you!"

The brain's functions are almost entirely limited to data calculation; it lacks any attack capabilities.

The level two access permissions set by Ye Feng are practically the same as level one permissions, unless there's a conflict between the two...

"This is a brain I designed based on your calculator, using binary calculations... It's infused with the energy of two immortal stones, allowing it to regenerate... It also has external connectivity; if the energy runs out..."

Just as Ye Feng was explaining, a gasp suddenly came from the side.

"Senior brother! The token!!"

Token?

Ye Feng casually picked up the token hanging from his waist.

At the center of the token, a small black dot had appeared out of nowhere!

This means that someone has withstood his attack and broken through his defenses!

"Don't worry, there's still time!"

Ye Feng was completely isolated from the outside world in his cultivation space. Even the Heavenly Ladder Domain couldn't sense the token's presence until he left the cultivation space, at which point the token received a signal...

The contact was established just two days ago.

This is also why he set himself a three-day deadline.

I just never expected that someone could actually do it!

This first test has no tricks or techniques involved.

It's all about strength and defense...

Ye Feng continued to explain to Ma Qiling,

"Now that I've given you the authority, you can arrange anything directly... If it doesn't know how, you can teach it..."

Ye Feng granted her extensive access; even if Ma Qiling wanted to open it and look inside, there would be no obstacle.

Of course, he doesn't have the strength to cause any damage.

Although it has no offensive capabilities, its defensive power is top-notch, thanks to the many items crafted by celestial beings. Without the power of a Celestial Venerable, you can forget about causing it any damage.

Ma Qiling received the item from Ye Feng with reverence in her eyes and immediately began to use her divine sense to study it.

Ye Feng had meticulously mapped out hundreds of trillions of interconnected links within the chips inside.

Even a small command would be an almost impossible task for Ma Qiling to complete by following the calculated trajectory in a short period of time.

Task completed, time to get down to business...

Ye Feng looked at the token in his hand and pondered for a moment.

Even a casual spell he unleashed, imbued with the chaotic laws of the fifth level of the Tribulation Transcending Realm, was not something anyone could break.

Aside from Ling Fengxue, and the unfathomable Shadowless Immortal Lu Xiande,

Ye Feng really couldn't think of anyone else who could do that...

Could it be?
