Time is still losing little by little, and there is not much time left for Luo Xiu.

Now they have only entered the first floor of the genetic research and development building, and if they want to rush to the top floor, there are still 66 floors waiting for them, and God knows how many enemies there are here.

The elevator can't enter, and the emergency escape corridor has been blocked by the other party, and it is difficult to rush up.

The other party's power system must be cut off first, otherwise they will be exposed to enemy surveillance probes, and the mission will become more difficult.

The entire building was pitch black, and the enemies were hiding in the shadows, giving Luo Xiu an even greater challenge.

The four men clung to the wall, moving forward step by step, and there was mortal danger everywhere.

Luo Xiu was just about to turn the corner when he heard a burst of gunfire not far away, followed by countless bullets.

Bullets flew almost across his face, corners crackling, sparks dotting, and dust flying.

There are enemies in the passage ahead!

He shrunk back, pulled out a stun bomb from his backpack, ripped off the pull ring, and threw it out.

The stun bomb bounced off the wall, refracted and bounced, and then the light flashed and there was a bang.

At the moment when the stun bomb exploded, Luo Xiu rushed over with a shotgun, only to see a hall in front of him, and several figures were lying on the ground with their heads in their hands.

The shotgun fired decisively, click-click! Click-click! Click-click!

Wherever the buckshot went, those people were killed in seconds.

……

The tigers also rushed out and began to clear the field, and the twelve people in the entire hall barely fought back, and they were collectively annihilated.

The entire hall has been controlled by Luo Xiu and others, and next to it is the entrance of the gate.

Fortunately, they didn't come in through the gate just now, and more than 20 people squatted here, and they would definitely be beaten into a hornet's nest in an instant.

Looking around, first clean up all the monitoring probes, a few big words on the wall come into view, very eye-catching.

"Tianjin Gene" R&D Technology Co., Ltd.!

The name is very domineering, but Zero Luo Xiu is very unhappy.

Mad Dog and Raccoon are on guard, and Rosho and Tiger discuss the next battle plan.

First, cut off the power to the entire building, so that the other party's monitoring probe is ineffective. Then, with the help of the ability of night vision devices, it is the only way to kill from the emergency escape route.

After agreeing on the tactics, Luo Xiu found three more bronze-level treasure chests in the hall.

It's full of universal magazines and healing potions, and there's a stun bomb in each.

It's already very good, otherwise with their ammunition, they won't be able to rush to the top at all.

Countdown: 16:23:19.

Luo Xiu had been in the game for almost eight hours, without sleeping, resting, drinking or eating, or even going to the toilet. The nerve cells of the brain and the whole body are in a state of tension all the time, which consumes a lot of energy on the human body.

This is not only a test of the player's skill and intelligence, but also a test of the player's physical fitness and mental strength!

The brain felt a little tired, and a burst of drowsiness hit, and Luo Xiu also forcibly cheered up. You can't rest now, or everything will be wasted.

I finally came here, and I can't just give up.

Some ammunition supplies were replenished, acting according to the predetermined tactics.

Without separation, the four of them began to clear the floor of all the enemies from the area, piece by piece.

Found the electrical room in the northeast corner of the first floor, Luo Xiu held a shotgun and sprayed wildly inside.

Bang bang bang......

The electrical room exploded instantly, spewing out a large cloud of electric sparks, which rattled and the electricity rushed wildly.

It was obvious that the camera overhead had dimmed, and Luo Xiu made a neck wiping motion at it, with a cruel smile on the corner of his mouth.

The four of them came to the staircase of emergency escape again, Luo Xiu flashed out with an AWM sniper rifle, and when the crosshair overlapped with the green light point above, he opened fire decisively.

The recoil of the sniper rifle could be clearly felt, and the bullet came out of its chamber, breaking through the silencer's gunfire, turning into a golden point of light and leaving with a scream that tore through the air.

After firing, the body flashed back again, and the movement was very fast.

This is a very classic action in the game - flash sniper!

After flashing back, the bullet casings bounced out of the sniper rifle and tumbled in the air, landing on Luo Xiu's feet.

Bite! Successfully kill a member of the security team and reward 100 experience points and 10 credits.

When the system prompt sounded in his ears, Luo Xiu saw a figure fall directly from above, hung on the railing, and fell into the underground parking lot on the negative third floor, followed by a muffled sound of a heavy object falling to the ground.

Luo Xiu didn't have time to think about it that much, his body had already flashed out again, and the sniper rifle fired again.

Bite! Successfully kill a member of the security team and reward 100 experience points and 10 credits.

The system prompt sounded, and another figure fell, snapping.

The other party didn't even have a chance to fire, Luo Xiu flashed out again with a sniper rifle, and it was another shot!

This shot can clearly be seen from the scope of a guy whose head has been blown up, and the body is hanging limply on the guardrail, and the gun in his hand has fallen.

Bite! Successfully kill a member of the security team and reward 100 experience points and 10 credits.

Three shots, three kills in seconds!

That's it!

When Luo Xiu flashed out for the fourth time, there was no one in sight of the sniper rifle, so he flashed back again.

After a few temptations, to make sure that there was no one to defend above, he made a safe gesture to the tiger and the others.

"Up!"

The tiger rushed out as soon as possible, and Luo Xiu and the three followed.

This time, Luo Xiu had replaced the sniper rifle with a UZI submachine gun, which was mounted on the tiger's shoulder, carefully guarding his vigilance.

Four people climbed up the stairs, making sure to miss every corner of the view.

Second floor.

Third floor.

Fifth floor.

Tenth floor.

……

It's already on the fifteenth floor!

There was a deathly silence in the hallway, and there were no enemies.

The more this happened, the more the fighting nerves in Luo Xiu's whole body became tighter.

This is the calm before the storm, and the quieter it is, the more tragic the battle will be.

Luo Xiu subconsciously took out a Stinger-type blasting mine from his backpack and put it at his feet. He had gotten five of these mines, and he had been reluctant to use them, and the current silence made him a little restless.

When they reached the twentieth floor, Luo Xiu once again placed a mine under his feet.

The enemy still didn't show up.

On the thirtieth floor, Luo Xiu dropped another mine.

When the four of them were about to continue walking, suddenly the doors of more than a dozen floors up and down were slammed open, and a group of people rushed out.

In an instant, the UZI submachine gun in Luo Xiu's hand had already fired, and the bullets were soaring!
