Bloodthirsty Bats, Polluter's Arm.

An hour later, Lao Yao was pushed into Lu Yuan's operating room number four by Liu Yuan.

In the few minutes before the anesthetic took effect, Lu Yuan came over.

Wearing surgical gowns, masks, hats, he looked at Lao Yao lying on the operating table and said, "Let me confirm some contract details with you one last time, you can still back out now if you change your mind."

Lao Yao nodded, and Liu Yuan next to him picked up a special DV and started recording.

"Your request is to become the strongest ability user possible within a budget of 5 million yuan."

"To that end, you have chosen biological prosthetics. Due to the principle of rejection in the human body, your body may develop some non-life-threatening or mobililty-impacting physiological characteristics in the future. You understand this and are willing to accept this situation."

Lao Yao nodded again. "Mmm-hmm."

"The heterologous genes and cell modules you have chosen are from the Bloodthirsty Bat. It will allow you to continuously enhance your body by drinking blood, although the growth potential is very high, it will not increase your combat power too much in the early stages."

"To this end, you have chosen to transplant the arm of a secondary pollution zone survivor to ensure your combat capability in the early stages."

"Because it is the arm of a polluted survivor, from now on you will need to spend at least one week in the pollution zone every month, otherwise your arm will atrophy and go necrotic."

"You understand and are willing to accept this situation."

Lao Yao took a deep breath on the operating table and repeated: "I understand and I am willing to accept it."

Lu Yuan pointed to the IPD on the side and said, "Alright, there are five minutes left before the anesthetic takes effect. If you have no objections you can confirm your fingerprint now, remember to use your left hand, because after today your right hand won't be on your body anymore."

Lao Yao reached out his left hand and pressed his fingerprint on the IPD, completing the contract signing.

Lu Yuan then turned to Liu Yuan and ordered: "Underground warehouse, 2nd floor, Section C, number C-129, Section L, number L-65, use low temperature storage boxes to bring them here."

"Okay."

After Liu Yuan left, Lu Yuan stretched his limbs and hand joints a little, then took out his tools one by one - drill, hacksaw, sledgehammer, chisel, pliers, full set of 108 scalpel blades...

Soon, Lao Yao fell into a drowsy sleep due to the effects of the anesthetic.

Liu Yuan pushed a trolley and stopped outside the operating room, placing an oblong and a square low temperature storage box on the workbench next to the operating table, and opened them one by one.

Instantly, white mist gushed out. Inside the oblong low temperature storage box was a dark bluish arm.

It was clear that this should be a human arm, but because of infection from the pollution zone, the entire arm was pitch black and cyanotic, with huge thick fingers, and sharp metallic luster flashing on the fingernails.

Lu Yuan held up this arm and compared it with Lao Yao’s right arm, muttering to himself, "About the same, this will work."

Then he looked at the second square storage box, which contained the hematopoietic organs of the heterologous Bloodthirsty Bat.

Taking a deep breath, Lu Yuan's eyes showed infinite excitement again as he looked at the sleeping Lao Yao.

"The exciting moment is coming..."

...

Because Lu Yuan woke up in the evening, the operation lasted until more than 2 am.

But even at this point, after nearly eight hours of highly focused continuous work, there was not the slightest sign of fatigue on Lu Yuan's face.

When he came out of the operating room, he just excitedly muttered to himself: "So amazing, so amazing! The dominant factor of biological limb manifestation can actually be controlled at will!"

With Lu Yuan working so late, little nurse Liu Yuan also worked overtime with him.

She looked at Lu Yuan speechlessly and reminded: "Boss, remember to go eat something, don't die on me..."

However, Lu Yuan seemed not to have heard her, waved her off and left.

The next day at dawn.

Lao Yao groggily opened his eyes and saw the ward in front of him. He was shocked, then remembered that he had the surgery.

His first reaction was to check his body, but at first glance there was no visible change at all.

Lao Yao raised his hand and slowly slid it back and forth over his chest and abdomen before he felt a shallow scar about 20 centimeters long.

This scar could only be felt by hand and was basically invisible to the eye.

At this moment, Lao Yao's first reaction was not to marvel at how skilled Lu Yuan's surgical sutures were. The first thing he wondered was -

have I been duped?

Just as Lao Yao was puzzled, suddenly, he saw the right hand he had just raised.

At this moment, goose bumps rose all over Lao Yao's body!

"Oh... My... God..."

Lao Yao's eyes were full of shock!

He carefully examined this right arm. Lao Yao was certain that from hand to arm, this was definitely not his original part!

This arm was as thick as his two previous chopstick-like arms combined, and was pitch black all over!

When he hadn't noticed this arm before, Lao Yao didn't feel anything, but now that he had noticed it, he only felt that his right arm seemed to have inexhaustible strength!

He flexed slightly and the muscles in that right arm immediately bulged out like inflated balloons!

In addition, what shocked Lao Yao the most were those hands - the five fingers were so black, thick, hard and long!

And those sharp nails flashing metallic luster!

Lao Yao looked at the steel crossbeam on the bedside table and lightly brushed it with his hand -

Swish!

A harsh metal snapping sound rang out as the crossbeam neatly snapped in two!

Yet Lao Yao only felt as if his right hand's sharp nails had pierced through something soft and squashy!

Next, he grabbed the steel railing on the side of the hospital bed and pulled hard!

Crack!

With the bed shaking violently, Lao Yao easily ripped off half of the railing with minimal effort!

Staring at that piece of steel railing in his hand, Lao Yao’s heart was about to jump out of his chest!

With this arm, such agility, such strength, such sharp claws!

At this moment, Lao Yao understood that just this arm alone was worth his 5 million!

As an intelligence broker for the Tianyu Medical Group headquarters in Xiyang City, Lao Yao was very clear on the pricing of prosthetics in the medical field!

The biological prosthetics of the Tianyu Group often started at a minimum of tens of millions, and despite being called “biological”, they were actually metal prosthetics with synthetic skin!

Not to mention the restricted mobility of such prosthetics, the key point was that they could only satisfy basic daily needs at best, and could never match the extreme combat capability of the biological prosthetic currently on his body!

The more Lao Yao thought about it, the more shocked he became!

Suddenly, he felt something growing in his mouth as the thought arose!

Lao Yao looked in the bedside mirror and found that his teeth had also changed!

Four sharp fangs had grown from his gums!

At the same time, an intense feeling of hunger and desire to eat arose from deep within him!

And as his thoughts shifted again, those four fangs gradually reverted back to normal teeth!

Lao Yao murmured to himself: "The Bloodthirsty Bat's genes and cells have taken effect?!"

By now Lao Yao was somewhat numb, and he even wondered if he was still under the influence of the anesthetic and hadn't woken up yet.
