He had just married a policewoman when he was diagnosed with criminal genius.

"Group A assault troops, Group A assault troops, please respond..." Ding Jianguo anxiously contacted.

"I'm sorry, Director Ding, they've become my prisoners." Lu Chen's voice came through the walkie-talkie.

Ding Jianguo was stunned.

What's going on? Group A just broke in, how did they get captured?

Ding Jianguo is now a little confused about the situation inside.

I never imagined that a simple joint police-bank exercise would actually put me in such a predicament.

The key is that he can't let Lu Chen go easy on him.

This was done in order to make the exercise somewhat more interesting.

His order to Lu Chen was to perfectly mimic the behavior of a real robber during a robbery.

The key point is that Lu Chen's imitation is too realistic now.

They were always able to handle their attacks with ease.

It seems they had anticipated that they would act this way.

Ding Jianguo did not reply.

Instead, he directed Group B to continue breaking down the side door and rushing in.

10: 30.

Team B finally broke through the side door and rushed in.

To their surprise, they were greeted by a tightly closed fire door.

Lu Chen locked the fire door from the inside five minutes ago.

This is part of the bank's internal fire protection system; once locked, it can only be opened from the inside.

Group B is trapped in a two-meter-wide corridor between a side door and a fire door, unable to move forward.

"Command center! Team B has been blocked! The suspect blocked the fire exits beforehand!"

Ding Jianguo suddenly stood up.

He didn't expect that Lu Chen would even be able to use the bank's existing facilities.

It seems that Lu Chen has a thorough understanding of the bank's plans.

Lu Chen put in a lot of effort for this robbery.

He finally realized that this was not just a formality.

At this moment, Ding Jianguo finally put away his contempt.

10: 35.

The command vehicle outside was in complete chaos.

Ding Jianguo made three phone calls in a row.

"Director Ding, what's going on? It's just a drill. In previous years, people would have already been heading back by this time, right?" Zhou Weidong's voice came from behind.

"Stop talking nonsense! Bring over all the special police and criminal police officers we can from our bureau!" Ding Jianguo shouted at the top of his lungs.

"If that's not enough, temporarily transfer colleagues from other branches as well. Take this opportunity to bring them all over for a good drill, let them see what a truly intelligent robber looks like."

Ding Jianguo really doesn't have many people he can use right now.

There was a sniper on the opposite balcony; he was just brought in to make an appearance.

To encounter a real robbery, you need at least three shooting positions.

Meanwhile, the members of Group A were "eliminated" by Lu Chen.

Team B member Ding Jianguo cannot move. Even if the side door cannot be opened, he cannot easily evacuate.

Otherwise, Lu Chen could easily escape from there.

We can only bring in more people to conduct the drill.

Police tape had been put up on the road in front of the bank, and the crowd of onlookers was growing larger and larger.

Lu Chen was no longer in the bank lobby.

He knew that one of the two groups of special police officers had been blocked outside the fire door by him.

One group was "destroyed" by itself.

It will take some time before Director Ding and his team can organize the next operation.

This period of time presents a good opportunity for Lu Chen to take action.

Lu Chen arrived at the corridor where the vault was stored.

The lights are off.

The power has been cut off.

But he had prepared a headlamp beforehand, the kind miners wear, with a beam of white light shining precisely ahead from his forehead.

He stood in front of the C-level vault.

This door is 2.2 meters high, 1.5 meters wide, and a full 18 centimeters thick.

Chromium-molybdenum alloy steel, with an embedded explosion-proof design for the door frame, capable of withstanding 50 tons of impact.

Two beautiful gold-plated locks with UV certification from the United States: one double-headed mechanical combination lock and one time lock.

According to national standards, a Class C vault door should be able to withstand damage for more than 120 minutes.

In other words, even if you bring an electric drill, a flame cutter, and explosives all at once, you might not be able to gnaw a hole in two hours.

Old Zhou, the vault manager, was "invited" to the corridor by Lu Chen. His hands were tied with cable ties, and his expression changed from disdain to shock.

"Young man, isn't this a drill? Are you really planning to open the vault?"

Lu Chen ignored Lao Zhou and began to study the "super lock".

In order to complete the bank robbery task assigned by Director Ding.

Lu Chen looked through all the tender documents from this bank several years ago.

They discovered that they had purchased this Class C vault security door.

At that time, Lu Chen was thinking about how to break through this metal fortress.

"Young man, don't bother," Old Zhou sighed, his tone even carrying a hint of sympathy.

"No more than five people in the entire Jiangbei City can open this door, and they all need a password and a key. You're just a drill participant..."

Old Zhou paused for a moment and then continued, "Young man, to be honest, it's quite impressive that you've managed to hold on this long."

"In all the years I've been here, you're the one who has persisted the longest and resisted the most among the simulated criminals."

"That's good enough."

Suddenly, Old Zhou's eyes widened.

"No, what are you trying to do, kid?"

He didn't even look at the lock.

Lu Chen took off his headlamp, turned the beam to its brightest setting, and then lay face down on the ground, his cheek pressed against the cool marble floor, his gaze sweeping along the bottom of the door frame.

Old Zhou frowned: "What are you doing lying on the ground? Looking for ants?"

Lu Chen ignored him.

He was looking at the door frame.

It's not about looking at the lock or the hinges, it's about looking at the anchoring area between the door frame and the wall.

That ten-centimeter-wide stainless steel decorative strip.

He knew the installation specifications for Class C vault doors by heart.

The door frame is fixed to the reinforced concrete wall with M16 chemical anchors, with the anchor spacing not exceeding 300 mm and the embedding depth not less than 120 mm.

The decorative strips serve to cover the anchor bolt heads and glue injection holes, while also preventing the internal structure from being seen through the gaps.

However, the decorative trim strip itself is only fixed with four M4 Phillips head screws.

Lu Chen took out a precision screwdriver from his waist bag.

The blade width is exactly four millimeters, and the handle is made of titanium alloy.

He pried open the first screw on the lower left corner of the decorative strip.

"You…" Old Zhou propped himself up, his smile frozen on his face, "You dismantled the door frame?"

Lu Chen did not answer.

The second one, the third one, the fourth one.

The pressure strip springs open.

What is exposed is a row of neatly arranged chemical anchor heads.

Hex head, M16 specification, with factory-applied anti-rust coating.

Each one was firmly embedded in the wall, without moving an inch.

Old Zhou breathed a sigh of relief, his smile returning: "See? These anchors are driven twelve centimeters deep into the wall, and they're even filled with epoxy resin. Even if you removed ten, it wouldn't..."

"I won't remove the anchor bolts."

Lu Chen's voice was very soft, but the corridor was unusually quiet, and Old Zhou could hear it clearly.

Lu Chen brought his headlamp close to the head of the anchor bolt, took out a fluorescent marker from his waist bag, and drew a circle on the wall between the two anchor bolts.

Then he changed his tools.

An M8 Allen wrench with a T-handle, with an extension rod attached, totaling forty centimeters in length.

This is not for tightening screws.

Lu Chen placed the top of the extension rod against the circled area.

That is the weakest stress point in the wall between the anchor bolts.

Then he took a small bottle of liquid out of his pocket.

The bottle had no label, was made of clear glass, and contained a colorless liquid.

Old Zhou, a veteran banker, immediately spotted the triangular hazardous materials symbol on the bottle, his pupils contracting sharply: "What's that?!"

Old Zhou didn't know what it was.

But he still knew the dangerous chemical symbols.

I never expected that the people participating in this exercise would be carrying something like this.

He looked at Lu Chen's stern and handsome face, feeling somewhat dazed. Was this really a drill?

……

Lu Chen smiled and said, "Acetone plus dichloromethane, in a 7:3 ratio."

The strength of chemical anchors depends on the quality of the adhesive application, and epoxy resin will degrade from a cross-linked structure to a linear structure in mixed solvents.

Simply put, no matter how stiff the glue I pour in, I can turn it back into soft mud.

The Thousand Machine Lock skill is capable of cracking all locks in the world, and this is no exaggeration.

Lu Chen's bright white teeth sent a chill down Old Zhou's spine in the dimly lit corridor.

He can't actually open the vault door, can he?

This is a Class C vault door, the world's most prestigious vault door?

Lu Chen drew five milliliters of mixed solvent with a syringe and slowly injected it along the wall of the anchor bolt hole.

The liquid seeps in very slowly.

Lu Chen stared at the opening, his right hand as steady as if welded to the wall, pushing the syringe at an almost constant speed.

Old Zhou fell silent.

He had worked in vault management for twenty years and never imagined that someone would target the adhesive layer of the chemical anchors.

Security assessments of all bank vaults focus on doors, locks, and alarm systems.

No one has evaluated the adhesive layer between the door frame and the wall.

But Lu Chen had considered it.

Five minutes later, the first anchor bolt.

Lu Chen attached the extended handle of the Allen wrench to the head of the anchor bolt, and turned the T-shaped handle horizontally to form a lever.

He didn't exert himself too much.

Hold the end of the handle with your right hand, and place your left hand lightly on the middle of the shaft to feel the force, then slowly apply torque.

The direction is not to loosen it, but to pull it outwards along the axial direction of the anchor bolt.

This is a technique that requires extremely fine touch.

Epoxy resin does not soften instantly after degradation; rather, it gradually loses strength starting from the surface layer, while the inner layer remains hard.

If too much force is applied, the anchor bolt may break inside the wall along with residual adhesive, making it impossible to remove.

Lu Chen felt resistance.

Like a blind person reading Braille, he uses an extended rod to transmit the minute deformations received to determine the depth to which the adhesive layer has degraded.

"It's over."

Lu Chen's words made Lao Zhou's heart skip a beat.

He really wants to go out and find their leader now.

Ask their manager.

Was this the original script?

This kid seems to have opened our bank's vault really fast.
