Chapter 197: Fierce firefight in the spiral staircase

Tang Yu found that these rare items were mainly concentrated in the rooms that required laboratory key cards to enter.

For example, [Laboratory Key Card. Black] can open the room of G12 laboratory on the second underground floor. The doors of these laboratories are all made of high-strength experimental glass and alloy.

So it is impossible to enter these real areas by breaking the door locks. There is only one way to get in, that is, the key card.

And Tang Yu now has a total of three laboratory key cards.

They are black card, red card and green card.

He still lacks yellow card, blue card and purple card, which he does not have!

So Tang Yu is waiting now.

He is waiting for kind people to open the three doors for him!

Although the sudden closure of the laboratory escape passage surprised everyone, fighting and death are still the main themes here.

Only 2 minutes later, fierce fighting broke out again, and gunshots were heard.

Tang Yu took the raccoon to wander around the third underground floor, while other survivors all focused on the high-level material areas on the second and first underground floors.

The two were sweeping all the supplies on this floor.

"Boss, are we really not going to compete with them for rare supplies?"

Little Raccoon asked with some concern.

"No, don't worry, let them search first, so we don't have to look for them again. Anyway, they can't take any out. When they have collected what they should collect, we can go and get it!"

At this moment, Tang Yu noticed from the virtual map that two more survivors were killed.

At the same time, he also noticed the rare title [Death Controller] Jigula Tang.

And beside him were two survivors of the Ten Thousand Races emitting red light, but the movements of these two people seemed a little unnatural to Tang Yu.

"This should be the enemy controlled by Jigula after being killed!"

Because the three underground floors are basically various machine rooms that maintain the normal operation of the entire laboratory, there are not many advanced supplies.

Passing through the messy corridors, Tang Yu and the others found several weapon and ammunition boxes.

After opening them, they saw that there were some weapon accessories and several tactical accessories inside.

And these ammunition boxes are all space containers, so Tang Yu directly put all these ammunition boxes into the backpack space.

One box and one space, it's so convenient, Xiaohuanxiong was stunned.

The two spent more than ten or twenty minutes to search all the supplies in the entire underground third floor, and then they were ready to go to the underground second floor.

They came to the spiral staircase passage, and the walls were painted with blue coating.

From here, you can go directly up to the underground second floor and the underground first floor.

Go out from the underground second floor, there is a T-shaped corridor intersection on the right, and the black card laboratory is at this T-shaped intersection.

Tang Yu and Xiaohuanxiong have come to the left and right sides of the fire door on the underground second floor. Through the glass on the fire door, you can see that the corridor is very quiet and empty.

But through the virtual map, Tang Yu saw that two senior survivors were squatting in different positions and waiting quietly.

And one of them squatted in the toilet, with the muzzle of the gun just pointing at the staircase fire door where they were.

Tang Yu frowned slightly.

These guys are really not a good person. They are all waiting for other people with key cards to open the door for them, ready to sit back and enjoy the fruits of their labor.

Little Raccoon noticed the expression of his boss.

"Old..."

He was about to speak, but suddenly saw Tang Yu's index finger on his lips, and he shut up immediately.

Tang Yu had already pointed the muzzle of his gun at the top of the spiral staircase, moving quietly.

This spiral staircase passage in the CBS laboratory was built tightly against the wall.

In the virtual map, a survivor of the Ten Thousand Races with three eyes on his head moved his feet carefully.

He just learned from a rare item that two survivors were hiding there.

The three eyes aimed at the gap under the stairs through three different sights on the specially modified guns.

The footsteps moved little by little on the steel plate, fearing that the slightest sound would attract the attention of the enemy downstairs.

Tang Yu was also waiting for the enemy upstairs to appear.

But it was obvious that he could wait patiently for the enemy to slowly appear, but someone couldn't wait any longer!

On the second floor underground, the survivor who had been hiding in the B12 computer room area and setting up a gun seemed to have relaxed his vigilance because no enemy appeared after waiting for such a long time.

He quietly left the computer room and walked towards the black card room.

As a result, just as he walked down three steps and passed the fire door of this spiral staircase.

A gun suddenly appeared in the bathroom opposite the black card room across the corridor.

And the survivor had been alert to that position for a long time.

The two opened fire almost at the same time. Although they were wearing high-level armor, as senior survivors, they had long understood the importance of high-level bullets, so they used high-level enhanced armor-piercing bullets without exception.

The survivor was shot in the chest, abdomen, and legs, and the survivor hiding in the bathroom was not better, and was shot in the head by him.

Although he took the enemy away, he was already bleeding heavily, and he had to treat and stop the bleeding as soon as possible.

Otherwise, his health would be emptied in a few seconds.

So the survivor pushed open the fire door of the spiral staircase and hid in.

But....

But the moment he stepped into the fire door, he saw a little raccoon raising his head and smiling at him.

"Surprise?"

The survivor's pupils dilated immediately...

The next moment.

Bang...

Bloody flowers had already splattered from his head, and the powerful impact of the bullet directly knocked the level 5 helmet on the survivor's head to the ground.

At the same time as the little raccoon fired.

The three-eyed survivor on the spiral staircase above the two people also jumped out quickly at the same time. While he was still in the air, the muzzle of the gun was already aimed at the position of the little raccoon.

He even had a hideous smile on his lips.

But when he really saw the situation downstairs, his smile stopped abruptly.

Because his body had been hit by continuous bullets, the powerful impact even pushed his body backwards and hit the wall heavily.

And at this time, the three-eyed survivor heard the gunshots.

"Why do they know my existence? Shouldn't their attention be attracted by the survivor?"

It's a pity that no one will ever answer his question!

After Tang Yu and the little raccoon killed the two people.

After taking a look at the corpse whose items had all disappeared, Tang Yu quickly said, "Get out!"

After the battle just now, all the enemies around the black card room have died.

At this time, the number of survivors in the entire laboratory, including Tang Yu and the other two...

only 7 people left!!
