Fifty or so gold bars, together they were the size of a suitcase, yet they turned invisible in front of the two men.

Boris's optical invisibility isn't like the low-end stuff Huang Ban uses, which can only cover up to the skin. This advanced technology from the European Community utilizes unknown gravity-related techniques to bend surrounding light to achieve invisibility, and most low-power detection devices can't pick it up.

The downside is it has a huge energy consumption, requiring a separate high-energy battery pack, and in the invisible state, you can't see almost anything with the naked eye. You can only rely on other auxiliary tools like cameras and radars to transmit data back and work with a computing center to build a 3D scene map.

After confirming that they didn't leave any trace of the gold bars, the expert said in the channel,

"Sasuke, please."

"You can always trust Muye's sneaky chicken."

"Forget it, your friendship is really too heavy, I can't handle it."

In the midst of their banter, the vault suddenly emitted a piercing wail, an alarm was triggered.

Yes, it was Er Zhuzi who did it.

Woo——

Woo——

Like air raid sirens, the ear-piercing electronic sound violently shook every drug dealer remaining in the mansion. After a brief moment of shock, they quickly reacted, realizing someone had invaded the mansion and triggered the alarm system.

In an instant, more than a dozen patrol teams returned, surrounding the entire mansion so tightly that not even a cockroach could fly out from their encirclement.

Boom!

Boom!

The reinforced concrete floor slab began to shed dust as if a tank was driving over it.

After the alarm sounded, Doyle exploded with speed entirely uncharacteristic of his massive frame, charging down the stairs with a custom, large-caliber electromagnetic pistol in his hand, pulling at the security minion and asking,

"What happened? I've been upstairs for less than twenty minutes and I hear this damn sound. You better give me a reasonable explanation, or I'll cut your head off and use it as a bowl."

"Boss... boss."

The minion, lifted like a chick by the cuff, looked at Doyle's face, shivering so much his knees knocked, eyes and nose scrunched into a wad,

"The alarm came from the vault side, but our hacker was ambushed..."

The vault!

"Hurry up and check the surveillance! I need to know who did it!"

Hearing the vault was involved, the anxious Doyle flung his right hand, launching the minion like a bowling ball, then ran thunderously towards the basement stairs on two tree stump-like legs.

Someone broke into his vault?

No way, he had just come out of the vault, and his security was so tight. Even if the hacker was attacked and couldn't send any alerts, there was no way anyone could get his password and fingerprint info, right?

No matter what you've figured out, he's just upstairs, and the sound of the vault door turning couldn't be hidden from drug dealers pervasive in this mansion.

Are you a wizard opening a portal to steal from me?

Increasingly agitated, Doyle stood at the vault door conducting examination after examination, this was the first time he felt angry at his own rigorous security measures.

"Fuck! Fuck! Fuck!"

"Why can't this damn machine react a bit faster?!"

However, things were worse than he imagined. When the half-meter-thick alloy door was opened, the layers of paper currency were still quietly stacked on the side, not a single bill missing.

And the gold that was supposed to shine with a captivating luster, the precious metal that historically symbolized luxury, had entirely vanished from the vault without even leaving a grain of gold dust.

More astonishingly, the vault showed no signs of forced entry, the electronic system on the vault door confirmed it hadn't been opened during this time, and even the piles of cash were exactly as he had left them, missing only the gold.

"My gold!"

Doyle, like a madman, ran to where his dreams once piled high, waving his hands trying to grasp something from the air, but he didn't even feel a trace.

"My gold! Who stole my gold!"

After confirming his reserve gold was gone, his eyes blood-red, exuding murderous intent all over, even veins protruded on his scar-smooth bald head as if hair would sprout out.

"Find it for me! Find that thief! I'm going to skin him, hang him from the Jesus statue!"

His roar was like a volcanic eruption, a surging sea wave, a mushroom cloud from a nuclear bomb, echoing throughout the manor. But no matter how angry he was, he couldn't see the gold that was so close to him.

This more than four tons of gold made it extremely difficult for the expert and Killer Demon to carry, the closest spot just centimeters away from the rampaging Doyle, scaring the sweat out of them, luckily they wore stockings caps which were excellent at absorbing sweat.

Many often misjudge the weight and volume of gold due to movies, but gold is much heavier than commonly thought, two thumbs together is the weight of a one-kilo gold bar, several tons of gold is just the size of a drawer, the rows of gold often seen in movies could crush the iron shelf.

Otherwise, it wouldn't be said gold is buried in the earth's core.

The only reason the expert and Killer Demon could lift something this heavy was thanks to their blue-violet cybernetic body structure.
