After receiving the warning from the mongoose, Zhang Yu and the mouse were ready immediately, holding up the assault rifle in their hands and ready to shoot at any time.

The regiment leader walked behind with the Black Mamba. They had to clean one layer before they could continue, otherwise once there was a residue on one layer, the consequences would be unimaginable.

"Dadada..."

The sound of the ak-12 assault rifle sounded.

This is Zhang Yu's assault rifle. Only Zhang Yu uses the ak-12 assault rifle here, which means that there is a firefight below!

Immediately afterwards, the sound of the mouse's aug assault rifle also sounded.

"Dadada..."

This is the unique shooting sound of m-16, and the opponent starts to fight back.

"They are prepared and have a high combat quality. They injured one and did not lose their combat effectiveness."

Zhang Yu's voice rang in the radio headset, and the battle started instantly. It was impossible to go in quietly.

"boom……"

The explosion of the grenade came from downstairs, and the battle was very fierce.

"Kill one, don't come down for the time being."

The mouse's voice sounded, and it was obvious that the grenade just now was his masterpiece.

"Dadadada..." The sound of the rifle kept ringing, and both sides kept firing at each other.

"With fire support, their teams are all in this direction, Cat Cats are careful downstairs."

The mouse continued to shout, the aug in his hand kept roaring, and the firepower suppressed the opponent's shooting.

Hei Mamba rolled sideways and rushed down the stairs, seeing the scene in front of her immediately.

The enemy was in a corridor, and there were traces of a grenade explosion in the distance, and a corpse was lying on the ground. This was the result of the grenade explosion just now.

At the door of a room in the distance, people kept poking out their arms and shooting, and then quickly pulled them back.

Below, Zhang Yu is checking the passage leading to the third floor, keeping alert, not knowing whether the enemy will come from this direction.

"Cat cat, you and Nemamba go down, I will cover your mouse and change the magazine."

While the regiment commander ordered, the aug assault rifle in his hand also roared and a row of bullets shot out.

At this moment, a flash bullet was thrown out of the room in the distance.

"Be careful, flash bomb!"

The leader shouted loudly and hid towards the stairs upstairs, while the mouse hid towards the stairs downstairs.

It was obvious that the opponent began to prepare for counterattack and used the flash bang to open the way. The flash bang flashed instantly. Although he hid in the corridor, the instantly strong light still made the eyes of the two people sting.

"Dadada..."

Without time to pay attention to these things, the regiment commander's aug assault rifle roared at the first time, and it must suppress the enemy and not let the enemy come out easily.

At the Aries mercenary's rest center, Ares was holding an assault rifle in his hand. He never expected to be attacked on such a rainy night.

"Notify the host to block the gate and order the guards on the lower levels to come up to support immediately and turn on the defense system. I want to know the enemy's information, how many people?"

Ares roared loudly through the radio, and the base was attacked, and once it was lost, the consequences would be unimaginable.

"Head, the sheep is dead. I am fighting back. The opponent is very strong and has skillful tactical cooperation. He is a special force!"

The goat's voice sounded, and he had no results in his two consecutive counterattacks and was almost hit.

This has never happened in my combat history, which shows how powerful the opponent is!

"Damn it, the black sheep and the yellow sheep must have been attacked, how did they open the door and what was going on in the control center?"

Ares roared loudly, and he lost three capable generals just after the war started. This was definitely a shame for the mercenary legion of the Zodiac Palace.

"This is the control center. The first floor control room is occupied and is fighting for control. It takes 30 minutes to completely control the gate. There are a total of five enemies."

The response sound came from the command center. From the sound, it was obvious that he was very panicked. It was obvious that he had no idea about such an attack.

"Let the guards downstairs support us immediately, where are the five people?"

Ares yelled, the antelope, rock goat at the door, and the barbarian goat have already started to support the goat to launch a counterattack. Ares calls for the support of the guards downstairs to the control center.

Only five people dared to come to the place where they were guarding to make trouble, and Ares was furious.

I am the mercenary group of the Zodiac 12 Palaces. The most annoying thing is that I was killed three of my subordinates, all of whom were elite!

"The first guard team has gone up to support and immediately eliminate the enemy! Four enemies are in the stairwell and one is in the control room on the first floor."

The control center responded, and when he heard this, Ares felt relieved. He had four subordinates, and he did not suffer any losses in terms of number of people. There was also a guard team, and the enemy was dead!

An Ruosi walked towards the door with his assault rifle. He wanted to see who was so arrogant and rushed to attack the base.

"Dadada..."

The roar of the assault rifle did not stop for a moment. The regiment commander and the rat fired alternately, suppressing the Aries mercenary group.

"The regiment commander is not a solution, the ammunition is consumed too much!"

The mouse commander shouted now that he had fired out two magazines in a moment, and the ammunition carried by the two people could not withstand such consumption at all.

"Let it go and fight, don't suppress them, prepare the grenades. This is not our base, why are you polite?"

The leader immediately shouted to the mouse, "Continuing to suppress now is not a solution!"

"Captain, the enemy control center has begun to compete with me for control. I can only hold on forty minutes, and the gate will be closed forty minutes for the week."

The sound of the mongoose sounded, and many parties had begun to compete for control.

"Crocockroach, come and support the mongoose, look at the broken door, and don't let the door be closed. So hurry up, be careful of enemy reinforcements around the mosquito monitoring."

The regiment commander immediately ordered the cockroach to support the mongoose, and he and the mouse were trapped on the first floor. Next, let’s look at the Tag Cat and the Black Mamba!

Zhang Yu and Hei Mamba advanced towards the second floor. Just as they arrived at the second floor, Zhang Yu suddenly felt a crisis.

"stop!"

Zhang Yu raised his hand to stop Hei Mamba.

Then he took out a grenade and threw it directly into the second floor platform! Then Zhang Yu hugged Hei Mamba and hid on the steps.

"boom……"

The grenade exploded instantly, and the shouts immediately sounded, and there was indeed an ambush.

"Dadada..."

Zhang Yu roared angrily and took advantage of the other party's panic to start shooting violently.

The black Mamba immediately stood up and the g-36 assault rifle in her hand also roared, and cooperated with Zhang Yu to continuously shoot.

More than a dozen armed personnel wearing white work clothes on the second floor rushed out with M-16 assault rifles in their hands.

Four people at the door were hit by grenades and lying on the ground. It seemed that they were no longer possible.

Zhang Yu and Hei Mamba kept shooting, the security personnel in white work clothes were constantly hit and fell to the ground, and new security personnel kept rushing out.
