Afterwards, through Jack's introduction, Yun You almost understood the prosthetic equipment on his body.

Inside the Moscow Mule, excluding those LED lights and small screws, there are exactly three prosthetics.

First, subcutaneous torso armor, metal product, civilian grade, small workshop manufacturing.

As the name implies, metal subcutaneous armor is an alloy steel plate implanted under the dermis, which can significantly increase a person's ability to take a beating.

Compared to bulletproof vests and shields worn outside the body, subcutaneous armor is lighter and more flexible, able to adapt to more combat environments, so almost every mercenary would implant this kind of prosthetic.

Jack's subcutaneous armor is not high-end, just light armor produced by a small workshop, and it only covers the torso.

It should be okay to block small-caliber bullets, but when encountering large-caliber firearms or melee weapon prosthetics, this thing probably won't be of any use.

However, it also has an advantage, which is being completely mechanical, not connected to a network, and without a control program, so there's naturally no need to worry about hacker intrusion.

Jack's second prosthetic is located on the spine, named the "Blood Frenzy Type 2 Muscle Limiter," a product of giant enterprise military technology. It allows a person to temporarily lift their physical limitations, greatly enhancing muscle strength and nerve response speed, and even to a certain extent, precisely control muscle movements.

Earlier, when Jack used both hands to deflect Yun You's punch, he activated this prosthetic.

Although the name sounds cool, the "Blood Frenzy" prosthetic chip, in fact, is a low-end product of military technology, with a low price and many superior alternatives.

At the same time, early versions of the Blood Frenzy chip had many shortcomings, such as causing a sudden increase in internal blood pressure when activated, resulting in the rupture of large areas of blood vessels, which is how the name "Blood Frenzy" came about.

Starting from the "Type 3," the Blood Frenzy chip resolved this issue, but Jack's chip is Type 2, which, although having the highest power among several models, also has the most severe side effects.

For this reason, Jack's chip was only activated for one second.

If it ran for a few more seconds, it wouldn't even take Yun You to lift a finger, he'd suffer severe injuries by himself.

As for the third prosthetic, that is Jack's most important and core prosthetic equipment.

"Nanometer Vajra Bone," military technology manufacture, police grade, experimental prototype.

Although it belongs to the same military technology as the Blood Frenzy chip, the value and importance of the two are not on the same level.

Nanometal technology is the most important research project for the military technology company over the past few decades, with the giant enterprise investing tens of billions in R&D funds, and the Nanometer Vajra Bone being one of the inconspicuous outcomes.

According to Jack, someone of his rank shouldn't have qualified to touch the prototype.

But fortunately, when military technology was transporting the Nanometer Vajra Bone, the convoy was attacked by other corporations and scavenger tribes, and the entire convoy perished with their enemies...

At that time, Jack happened to pass by there, and he conveniently picked up the Nanometer Vajra Bone and immediately implanted it in himself.

One has to say, in Nest City, luck is really a strange thing.

You might become rich overnight and reach the pinnacle of life from a chance encounter, or you might fall to the ground and become part of the lower class due to a small accident.

This is Nest City No. 3, where anything is possible...

As for the effect of the Nanometer Vajra Bone, it is actually quite simple.

It resides within Jack's bones in daily life, passively strengthening the mercenary's bone hardness.

When Jack needs it, it can extend from his arms and legs, transforming into weapons or armor to adapt to needed environments.

Jack is currently exploring its potential at a very shallow level, only 1% of its capabilities, but the effect is already quite impressive.

The metal plate that blocked Yun You's knee strike is the best proof.

Currently, the mercenary mainly reported these three prosthetics.

However, Yun You has always felt that Jack, as a seasoned mercenary, should not only have these three prosthetics on his body.

He might still have something reserved.

But this is also normal, after all, Jack is just a verbal partner for the girl, expecting someone to reveal their trump cards on the first meeting is obviously not reasonable.

So Yun You didn't ask more questions and ended the interview.

"You've passed, mercenary."

The girl extended her hand and said calmly, "I wish us a pleasant cooperation."

"However, the payment might need to be delayed a bit because I don't actually have that much cash on hand now."

"It's okay."

Jack smiled and shook Yun You's bandaged hand, saying frankly, "I have a keen eye for people, and Miss Wu Ming is not someone who likes deception."

"Oh? How did you see that?"

Yun You asked curiously.

"Eyes."

Jack pointed at his own sparkling electronic eye.

"Eyes are the most honest part of a person, no matter how much you cover up, they still reflect the truest thoughts in a person's heart, and the Carlos Clan excels at seeing through the eyes."

"Bastards who enjoy domestic violence have a cold flame burning in their eyes, not hot, but it makes people shiver all over."

"Those used to betrayal and lies have an iceberg sitting in their pupils, appearing small on the surface, but beneath the water hides unimaginable deceit."

"And you... Miss Wu Ming, Apprentice Death God."

"Your eyes also hide fire and an iceberg, which can't be hidden even with sunglasses and colored contacts."

"But your fire burns hot, with no concealment of the anger in your heart. And the iceberg... though chilling, it's pure and without a trace of blemish."

"What I'm going to say next might be a bit offensive, please forgive me."

Noticing Yun You's gradually serious expression, Jack quickly raised his hand, giving the little girl a heads-up.

But he didn't stop explaining and continued, "If I'm not mistaken, your personality should be the kind that appears carefree on the surface, but in essence is quite decisive, even somewhat... crazy."

"At the same time, you have your principles and bottom lines, completely different from pure evil. Overall, you're trustworthy, at least worthy of my trust."

"I don't know if my guesses are right or not..."

"..."

Yun You didn't answer, just kept silent, using a big gulp of drink to cover up the waves in her heart.

Was Jack's guess right? Of course, it was.

She didn't know how Jack saw those things with an eyeglass, those icebergs and flames...

But this mercenary did indeed understand the little girl's character.

"Alright, since you're willing to trust me, there's no need to analyze further."

Perhaps not wanting her thoughts to be guessed accurately, Yun You didn't respond till the end, and just picked up her phone, brought up an electronic contract, and tossed it to the mercenary.

"Sign if everything's okay."

The little girl tapped the table with her finger, muttering, "Once you join, only a hacker will be missing from our team."

"But hackers are indeed hard to find, even rarer than mercenaries..."

Upon hearing these words, Jack was slightly taken aback, then subconsciously said, "Hacker? You need a hacker?"

"I happen to know a hacker, interested in meeting?"
