Delta: I have a 1-Haf Coin instant kill system!

"Hudson!"

"Don't have any thoughts you shouldn't have!"

"Kindness is worthless here!"

No response!

Or rather, silence is the response!

Zhang Zhao stood in the operating room, and that face finally matched the fragments of his memory!

Hudson!

Hafk's Minister of Efficiency!

One of the bosses in the Delta World from my previous life!

"As long as there is authorization, Hafk's arsenal is open to all!"

"You ask who to hit with it? Hafk doesn't care!"

When he first appeared as a boss, he was jokingly called the "Asthma Minister" by players!

But because of a special event, he became an angel investor in the eyes of many players!

Back then, who wouldn't call him "Minister of Efficiency"?

And now... the other side is just an ordinary Hafk soldier?

However, you remain an angel investor, Minister!

Zhang Zhao was filled with emotion, then quickly pulled himself together and silently recited in his heart:

"top up!"

The Huff Coin in my hand disappeared silently.

Current HAFCoin balance: 100

enough!

That's more than enough!

Zhang Zhao took a deep breath and his gaze fell on the three cards in the system shop.

[Ding—Purchase successful, 1 Haf Coin spent!]

[The ReLink brain-computer interface perfect fit sequence has been automatically loaded into the host cells!]

[Ding—Purchase successful, 1 Haf Coin spent!]

[M1 Muscle Strengthening Needle has been added to your system inventory!]

[Ding—Purchase successful, 1 Haf Coin spent!]

[The Shadow Special Equipment Set has been added to your system inventory!]

[Ding—Current Hafcoin balance: 97]

The cold, mechanical voice slowly faded from his mind, but Zhang Zhao didn't sense anything unusual.

But he knew in his heart—

He will survive the brain-computer interface experiment!

Moreover, it is not controlled by the terminal!

Live freely!

Zhang Zhao gently exhaled a breath of stale air and focused his consciousness on the system's inventory.

[System Backpack]

[M1 Muscle Strengthening Needle x1]

【Shadow Special Equipment Set x1】

The two items lay quietly in the backpack compartment, but Zhang Zhao did not rush to take them out to check.

This is not the right place.

The operating room door was still left ajar.

Zhang Zhao walked barefoot to the operating table, sat down quietly, and waited.

After what seemed like an eternity, the door was finally pushed open.

Zhang Zhao raised his head.

Rometheus wasn't the only one who arrived—he was followed by two soldiers.

But Hudson was not among them.

Rometheus looked at Zhang Zhao with a hint of surprise in his eyes.

He raised his right hand and waved it gently.

The two soldiers behind him exchanged a glance, said nothing, and left the operating room.

These two were originally called here specifically to prevent Zhang Zhao from struggling, but now it seems that the other party is cooperating?

The metal door closed silently, leaving only two people in the operating room.

Before Rometheus could speak, he saw Zhang Zhao lying face up on the operating table.

The movements were fluid and seamless, executed in one go.

A look of bewilderment flashed across Rometheus's eyes.

He spent nearly two years in the Tower of Babel, and handled at least eight hundred to a thousand experimental subjects.

Some cried, some made a scene, some knelt down and begged for mercy, some tried to resist but had their legs broken by Hafk's soldiers, and some were even so frightened that they lost control of their bladders!

But this is the first time someone has voluntarily lay down like this!

Are all Chinese people this brave?

"bring it on!"

Zhang Zhao placed his hands folded in front of his chest, his gaze calmly fixed on the overhead operating light!

"Should we use anesthesia, or should we just start?"

Rometheus remained silent.

He walked around the instrument table, went to the operating table, and looked down at the experimental subject.

He was eighteen or nineteen years old, with an East Asian face, and a slender but not frail build, suggesting he was in good physical condition and could last a long time.

Aren't you scared?

Rometheus asked in confusion,

Zhang Zhao turned his head and glanced at him.

"Is being afraid helpful?"

Rometheus's lips twitched slightly.

"You're more clear-headed than most people!"

He turned and walked to the equipment table, picked up the tablet and swiped a few times to bring up Zhang Zhao's information.

"Zhang Zhao, eighteen years old, Chinese, was purchased from the black market by Hafk's purchasing department for 10 Hafk dollars!"

Zhang Zhao's eye twitched when he heard the number.

10 Haff coins?

I'm only worth 10 Haff coins?

That bastard Reis, he knocked him out and sold him for 10 Haff coins?

He's made a note of that!

"His physical abilities are above average, but... his neurological responses are far beyond the norm!"

Rometheus put the tablet aside, picked up a pair of rubber gloves, and put them on as he spoke.

"Ready? Let's begin!"

His voice was light and airy, and the operating light on the operating table suddenly turned on with a "snap".

The blinding white light shone directly on Zhang Zhao's face, forcing him to squint.

Rometheus turned around and picked up a transparent syringe from the instrument table.

"What is this?" Zhang Zhao swallowed hard, staring at the needle.

"Anesthetic!"

Rometheus flicked the syringe to expel the air bubbles inside.

"Get some sleep first! When you wake up..."

He paused for a moment, then changed his words.

"If you can wake up, then congratulations~"

The needle pierced Zhang Zhao's arm, and he lost consciousness in an instant.

Rometheus waited a moment, then lifted Zhang Zhao's wrist, placing two fingers on his pulse and feeling the gradually calming beat.

He then lifted Zhang Zhao's eyelids and shone a flashlight into his pupils.

"Okay~ We can begin!"

He picked up the scalpel from the instrument table and began his work!

After an unknown amount of time, Zhang Zhao's head was successfully split open!

Rometheus put down the drill and picked up the chip from the machine table!

ReLink Brain-Computer Interface!

This is an optimized version following the first-generation brain-computer interface worn by the nameless individual!

Greater control!

It also has a variety of other functions that can help the wearer enhance their combat capabilities!

Another half hour passed, and the brain-computer interface was successfully installed on Zhang Zhao's brain.

After completing these procedures, Rometheus did not rush to sew up the wound.

Because it's unnecessary.

He's only had stitches done once in all these years!

That boy, Elie de Monbel, was trained by Hafk to be a weapon from a young age!

He has developed an exceptional physique through years of training!

He survived!

As for the others?

The person is dead; stitching them up is just a waste of time!

Rometheus put down the tweezers, took a step back, and removed his blood-stained gloves.

He looked at Zhang Zhao's open head, the chip embedded in the crimson expanse.

Blue light begins to flash on the chip surface—connection testing is underway...

Rometheus picked up the tablet, and the screen displayed a dense stream of data.

"ReLink brain-computer interface testing in progress..."

"Neural pathways are being established..."

Brainwave synchronization rate: 17%......23%......35%......

Rometheus raised an eyebrow slightly.

The synchronization rate is growing very fast.

The synchronization rate of most experimental subjects would get stuck below 40%, then plummet, brain waves would become disordered, and eventually brain death would occur.

But this Chinese man...

Brainwave synchronization rate: 41%......44%......49%......

Rometheus stared at the number, his fingers tapping lightly on the edge of the tablet.

49%!

It's stuck!

"What a pity! Just a hair's breadth away..."

He said something softly, turned around and walked towards the equipment table to start tidying up the tools.

After two years of experiments, Rometheus deduced that only subjects with a synchronization rate exceeding 50% could survive.

But 49% is 49%, and ultimately it will still happen—

Brainwave synchronization rate: 51%!

The tablet's notification sound made Rometheus pause.

He turned his head and looked at the screen.

Brainwave synchronization rate: 58%......64%......71%......

Rometheus put down the instruments in his hands and quickly walked back to the operating table.

He stared at the chip; the blue light was flashing at an increasingly faster frequency.

On the tablet, the data is still updating.

Brainwave synchronization rate: 78%......82%......89%......

Rometheus's finger hovered above the tablet screen.

An 89% synchronization rate—he had never seen anything like it before!

Even though it's an unknown company, it only accounts for 75%!

And now, it's still increasing—

"Brainwave synchronization rate: 94%......97%......100%!"

"ReLink brain-computer interface fitting complete!"

Rometheus stared at the tablet, momentarily stunned.

The experiment he had been looking forward to for more than two years finally began to take shape, leaving him at a loss for what to do.
