Disciple, please come down the mountain soon. Your senior sister can’t wait any longer.

Pei Xingchen, who was furious, immediately gave orders to leave some people here to organize the fire-fighting, and he led the rest of the people to rush to the hall door.

At this moment, the entrance hall of the underground base was already filled with the sound of gunfire and was extremely lively.

The originally heavy and majestic gate was now tilted to one side. There were gaps and curled iron plates everywhere on the gate, as well as traces of smoke and fire. It looked horrible.

Tian San and Tian Qi, who had successfully blew open the door, had already rushed into the hall with their men. Just when they broke in, the hall was urgently gathering people from the underground base to prepare to go to support Area 0.

The moment Tian San and Tian Qi led their men to rush in, they ran into the apprentices who were gathering in the underground base.

Across the smoke and dust that rose after the gate was blown open, the two sides stared at each other.

After just a second of being stunned, Pei Qingniao, who was shouting to the apprentices gathered in the underground base, immediately reacted and screamed at the top of his lungs.

"Enemy attack!"

"Take them all down!"

Pei Qingniao looked with almost ecstasy at the dozens of enemies in front of him whose faces were covered with gas masks and whose faces could not be seen clearly.

She was just worrying about how to shift the blame for someone breaking into Area 0 and how to reduce her own guilt. Unexpectedly, it was as if her wish came true, and she immediately found a good candidate to atone for her crime!

There is no doubt that these enemies in front of us must be related to the mole that sneaked into the underground base. The two sides must be in the same group!

As long as she can take down these enemies in front of her, then when Pei Runnian holds her accountable for the infiltration of the underground base in the future, she will have the confidence to exonerate herself.

You see, it’s not that I’m careless, but the enemy has been planning this for a long time!

They could even blow up the gate that could withstand the bombardment of the tank's main gun. No matter how cautious I am, how can I force out the enemy's all-pervasive infiltration?

What's more, I defeated and captured the invading enemy in the first place, thwarted their subsequent conspiracy, and saved the entire underground base.

With such a great contribution, it should be no problem for me to offset my previous mistakes!

Pei Qingniao became more and more excited as she thought about it. Her charming face was distorted and she almost jumped up and down while screaming and giving orders.

"Come on, get them all on me!"

"If you don't capture them for me, don't come back!"

Pei Qingniao screamed frantically and urged the apprentices gathered below to launch an attack, but Pei Qingniao, eager to atone for his sins, overlooked a most basic fact.

The men she was gathering were merely new recruits who were being trained in the underground base. They had only learned some of the most basic martial arts training and fighting techniques, as well as some knowledge of how to operate thermal weapons. They could only be considered semi-finished products at best.

As for the enemies standing opposite them, not to mention Tian San and Tian Qi, the two perverts at the peak of dark energy, the rest are all warriors who have received strict and complete martial arts training!

Some of them have even cultivated internal strength, and all of them have experienced the cruel trial of blood and fire, and have become true warriors with rich practical experience and powerful martial arts skills!

If the people under Tian San and Tian Qi are tigers, then those under Pei Qingniao are not even hyenas. At best, they can only be regarded as fat pigs with size but no strength.

Moreover, these fat pigs were unarmed and carried no weapons. At most, they only had some cold weapons such as daggers and short knives.

The group of tigers led by Tian San and Tian Qi were all armed to the teeth. In addition to their own powerful strength, they were also wearing level 120 bulletproof vests and helmets that could withstand bullets. They were holding -round assault rifles and high-explosive grenades and other powerful firepower in their hands. Compared with the group of apprentices under Pei Qingniao, they were completely crushed by a cliff!

Perhaps the only advantage they have is that they have several times more manpower than Tian San and others.

Pei Qingniao and this group of apprentices who had never experienced the cruelty of actual combat were indeed confused by this most obvious yet most useless advantage. Even though they were a little scared when they saw Tian San and others fully armed, they thought they had the advantage in numbers, but this was their territory, so after a slight hesitation, they immediately roared and rushed towards Tian San and Tian Qi.

Tian San and Tian Qi looked at the crowd rushing towards them and they looked at each other.

Even through the thick gas masks, the two people could still see each other's speechless eyes.

What era is this? How come there are still people who think having more people means an advantage?

The two shook their heads, not bothering to say a word, and just made a gesture.

The many men standing behind the two men had now dispersed, and it seemed as if they might be overwhelmed if they just stared at each other.

But if there were someone proficient in military affairs at the scene, they would have discovered that their seemingly loose positions had actually occupied various advantageous shooting angles and had blocked all angles of the enemy's charge!

After Tian San and Tian Qi made the gesture to take action, their men pulled the trigger without any hesitation!

"Da da da da da!"

The crisp sound of gunfire immediately merged into one, and the dense barrage of bullets immediately rushed into the oncoming crowd with the screams of death like a heavy rain, and countless flowers of blood splashed immediately.

The charging crowd was like wheat cut by a sickle. They fell to the ground one after another, screams rose to the sky, and the air was immediately filled with a strong smell of blood.

Even if some people were filled with passion and still mustered up the courage to charge forward, using the bodies of their fallen companions as shields, rushing forward, trying to break through the fire blockade in front of them, but it was still in vain.

Tian San and Tian Qi's subordinates were like sophisticated and cold-blooded robots. They did not waver at all in the face of the Shura hell-like scene before them. Their hands holding the guns remained steady, and they pulled the triggers steadily, continuously spitting out a barrage of bullets representing death.

Moreover, they did not just shoot mindlessly, but set up precise echelons of fire.

When the people in the first echelon have emptied their magazines and need to reload, the people in the second echelon still have more than half of the magazine capacity, thus ensuring that the intensive firepower will not be weakened and the enemy will not have any chance to break through the firepower blockade!

In addition, from time to time, someone would throw high-explosive grenades at the charging crowd, which made the apprentices bleed and cry for their parents. They were simply unable to break through the fire blockade that seemed like cast iron and steel!
