After receiving Mu Zeming's notice, Liu Le almost bit his back teeth: "I know, be careful to hide! Lien, prepare for battle, Zong Rui, make the worst plan!"

"Yes!" The two people answered at the same time. Ryan immediately lay down behind the corner of the fork, but Zong Rui slapped the high-energy plastic explosive into a thin piece the size of a palm, and put one on both sides of the passage and the top of his head, then he hid and waited silently.

The communication center is a building built according to the fortress standards. It is easy to defend and difficult to attack. Three people and three directions block the only entrance.

Liu Le stared sharply at the entrance: "Contracting workers, waiting for workers, how long does it take for you?"

Bao and waited for the two of them to check the equipment and replied after hearing this: "It's hard to say, it's been a long time since we used it. We must check it first and know the time after understanding the situation."

"Please hurry up, I don't know how long we can last!"

Bao Lin paused, but immediately continued: "I understand, let's get it as soon as possible!"

Liu Le suddenly was stunned: "Hey, isn't this place not a communications center? Why hasn't it been used for a long time?"

When Bao Lin heard this, he knew that Liu Le didn't understand the location of the important communication facilities at all: "After the new center in the East Fourth District was built, it was abandoned here and it should be regarded as a backup center, but the new center is too conspicuous, and the aliens are finished as soon as they arrive..."

Ryan's voice interrupted the call: "Captain, the enemy is coming!"

"Let's fire!" Liu Le roared. The three of them fired at the same time. The firepower was not fierce, but it was more than enough to block the narrow passage.

But the aliens rushed into the passage with their shields. The firepower of the three people fell on the shields, and there was no turmoil at all.

Liu Le suddenly cooled from his head to his chrysanthemum, and immediately slowed down his shooting speed, giving the beam rifle more time to charge, making each beam more powerful.

They are all old comrades-in-arms, and Lien and Zong Rui don't need to give any instructions. The former speeds up the shooting speed, not asking for damage to the enemy, but only asking for suppression. The beams are one after another, but each one has no power.

The latter, together with Liu Le, slowed down and increased his power, focusing on attacking positions where the shield cannot be protected.

Liu Le saw the opportunity and shot through the enemy's knee with one shot. The enemy immediately turned over and fell to the ground. Zong Rui made a shot at the right time, piercing the enemy's head and successfully killing the aliens.

The three of them were a little excited and were about to continue their efforts. The alien behind suddenly stopped. The one in front raised his shield and squatted down and blocked him with a shield. The second alien raised his arms and put them on his shoulders, firing at Liu Le, who was facing the passage.

Liu Le's cover was facing the passage, which was the most threatening position to the enemy. He could have avoided it, but the position of Ryan and Zong Rui was not good. In the midst of lightning, he suppressed the urge to avoid it and gritted his teeth and chose to fight hard.

The beam from the enemy hit Liu Le's right chest, leaving a deep scar on his armor, almost breaking through the armor.

Liu Le's counterattack also hit the enemy, and from the enemy's right forehead to the left jaw, it just happened to pass through his eyes. The alien suddenly flipped and rolled and struggled like a fish just off the water.

Not dead, but seriously injured and did not run away.

The successive success gave Liu Le great confidence, but it also gave him a certain understanding of the enemy.

Another enemy raised his arms. Liu Le did not dare to force himself this time, so he quickly retracted back to the cover, took off the individual grenade, and threw it into the passage based on his feelings.

His feeling was very accurate. The grenade fell into the passage accurately. Several aliens immediately changed their posture, and their arms raised were blocking in front of them, activating the shield to block the grenade.

With a muffled sound, the powerful shock wave led the enemy to the point of falling. The three of them took the opportunity to fire and got two more heads.

Opposite the street, Mu Zeming watched the enemy rush into the communication center, and heard the explosion again, and his whole heart was raised in the air. He was determined to ask what was going on inside, but he was afraid that Liu Le and others would be distracted.

Deep in the communication center, Bao Lin and Hou Yunfeng not only heard the explosion, but also felt a slight vibration. The two paused slightly, looked at each other and moved a little faster than before.

There are only three people who are guarding outside, and there is no idea when they can guard it, and no time can be wasted!

"Okay!" Hou Yunfeng growled and changed the last module.

A holographic operation interface appeared in front of Bao Lin. Her fingers connected in the air and activated the power test equipment: "Captain Liu, I will be fine here soon. Please be sure to hold on for a while!"

"Don't worry if you receive it!" Liu Le's voice was as steady as a rock, but the situation he faced took a sharp turn.

After paying a few enemies' lives, the aliens finally set off their best turtle formation, blocking the entire passage with shields, and constantly advancing forward at a slow but steady pace.

Near, closer!

Liu Le gritted his teeth tightly and kept firing at the enemy, but the firepower of the three people was of no use.

He began to consider detonating plastic explosives, but the communication center had only one exit. Blasting out the exit could indeed block the enemy, but it would also trap his own people here.

Since Liu Le has been eating the food of the army, he has never been afraid of sacrifice. Not being afraid of death does not mean that he does not want to continue living.

Without time to hesitate, Liu Le has made a decision: "Xiao Mu, how many enemies have come in in total?"

Mu Zeming quickly replied: "Sixteen!"

Liu Le was stunned: "Only sixteen?"

"There are enemy planes in the sky, but there is no intention to come down."

Liu Le immediately breathed a sigh of relief: "I understand, pay attention to the enemy's movements, and notify me immediately when the enemy plane lands."

"Yes, don't worry, captain!"

Liu Le took out the grenade and threw it out, and shouted: "Retreat!"

Ryan and Zong Rui were both confused and thought to himself, what should I withdraw at this time?

Although they were puzzled, they did not hesitate at all and immediately followed Liu Le to the depths of the communication center... This place covers a small area, but the interior is complex enough. With the terrain and the enemy, it is entirely possible to defeat sixteen enemies... No, four have been killed, and there are still twelve!

At this moment, Muzeshi saw the enemy sending several corpses out of the communication center, and two alien transport planes landed at the same time, one recycling the corpses, and the other releasing more enemies.

He immediately became anxious: "Captain, the enemy replenishes their troops, one... no, two, both have enemies!"

Mu Zeming no longer cared about Liu Le's instructions and immediately activated the air defense system: "Captain, I'm leaving, take care of you!"

Liu Le was completely confused: "Mu Zeming, what's going on in your situation? Mu Zeming, you're talking!"
