In an instant, silence became the main theme in the house.

No one fired a shot.

No one made a sound.

All that remained were faces scarier than the last.

This was a scene of terror they had never imagined.

One person, holding a handful of bullets, killed twenty or thirty people.

This...

This...

Is this a dream? Why can't I wake up from such a fright??

In the surveillance room, the highest-ranking members of the leadership didn't act; they observed the situation. They could leave only when things became desperate; otherwise, they would face the highest level of the organization's most terrifying punishment!

But now it seemed that punishment was nothing.

The horror of that punishment couldn't compare to what they were witnessing now.

"Downstairs, can they hold out for another two minutes?"

Someone inquired.

Unfortunately, no one could answer his question.

"Ding!"

The elevator doors opened.

The first batch of unaware support security forces had arrived. Led by the organizer, they reached the first floor.

They were the first batch, and there were two more batches on the way from other floors.

As soon as they stepped out of the elevator, they witnessed a scene they would never forget.

Corpses littered the floor.

Not a single living soul.

Except for Zhang Beixing, not a single living soul.

And Zhang Beixing coldly watched them from ten meters away.

They instinctively raised their guns and began firing.

No careful aiming, no deliberate targeting.

Nothing mattered.

They emptied their magazines, one after another, two, three.

Until each of them had expended five magazines, with two hundred rounds each.

The bullets weren't all directed at Zhang Beixing's direction; they hit walls, pillars, floors, and ceilings, everywhere.

The entire first floor was showered with debris, dust flying.

When the dust settled, a figure emerged.

Zhang Beixing stood before them, unscathed.

Danger!

At this moment, everyone instantly thought the same thing in their hearts.

Just then, the elevator rang again, signaling another batch of support.

Whoosh! Whoosh! Whoosh!

Slicing through the air, the sound came just then.

Before the newcomers could react, unknown objects struck all of them.

With intense pain from the impact, they convulsed and fell to the ground.

The entire elevator lobby was piled with corpses.

The last batch of security reinforcements arrived.

The elevator doors opened.

As the elevator doors opened, everyone was stunned, frozen on the spot, unable to comprehend the sight before their eyes.

After the doors opened, the corpses in the elevator lobby practically filled half the elevator!

Absolutely no way to get out!

And the person they came to encircle and annihilate.

Zhang Beixing.

At this moment, he stood atop the corpses, looking at them with a piercing cold gaze.

In both hands, he held bullet casings, tossing them into the air, only to catch them back again.

Those who just arrived didn't understand what he was doing.

The next second, the objects in his hands were thrown once more, but this time not upwards, toward them.

Whoosh! Whoosh! Whoosh!

...

...

A team was busy arranging to administer serum to subjects on various floors, aside from those summoning security to attack Zhang Beixing.

Dozens had already been completed.

But time was still too tight.

A few individuals were waiting for the elevator; it's not that they couldn't take the stairs.

It's just that this building was too tall, with too many floors.

Going from over thirty floors down to a dozen via stairs was too slow and too physically exhausting.

It wasn't friendly for glass vials containing serums either.

Finally, the elevator arrived.

Just as he was about to enter.

But upon seeing the scene inside, he froze.

Instantly, a strong discomfort from his stomach emerged.

He'd waited over a minute for the elevator.

Now it was filled with bodies.

And the face-up corpse on top was a colleague he just had a meeting with in the conference room!

"How dare he!!!"

Seeing the images transmitted back from numerous cameras.

Those in the conference room shook with rage.

Unable to trust their eyes.

Not only anger, but also a strong sense of fear filled them now.

What kind of person could, in less than two minutes, wipe out an entire security and mercenary force, nearly two hundred strong, without leaving a single one?

At this moment, surveillance captured Zhang Beixing starting to ascend the stairs.

In fact, when this building was constructed, the security measures were meticulous.

Virtually every stairwell had a security door.

These were exceedingly heavy iron doors, thirty centimeters thick, made with two layers of five-centimeter iron plates encasing twenty centimeters of poured concrete.

Each door weighed over a thousand kilograms!

Without special tools, opening the doors, even with a key, would be incredibly difficult for one person.

Yet in front of Zhang Beixing.

With just a single kick, he forced the door open!

And it seemed as though Zhang Beixing didn't even exert much effort!!!

Is this really human!

Watching Zhang Beixing effortlessly reach the third floor.
