The sound of a strong siren combined with the ubiquitous red siren lights signaled the strength of the alien forces that had come to support the pit base.

"Tell Hong Nanlong to quickly deal with the remaining alien troops, a new alien army has come to kill!" Xu Cheng said anxiously: "The rest of the people, oh no! Your team stays here to protect these two people, and the rest of us and I dare to go and support Hong Nanlong immediately!" ”

"Yes," everyone agreed.

Xu Cheng said, directly pulled out the pistol, carried the sword in one hand, held the gun in the other, and rushed out of the central control room directly with the trial team!

"Xu Cheng, how will we kill it later?" Zhang Jinyun kept up with Xu Cheng's pace and asked Xu Cheng about the arrangements for a while.

"How to kill? Stealing those guys' asses, of course! Xu Cheng said excitedly, "After a while, everyone will be divided into two groups and kill as quickly as possible, and I will let the soldiers of the second brigade launch a full-scale counterattack to echo our battle!" ”

At this time, due to the restoration of the normal supply of electricity in the passage, the visibility became exceptionally good, and the speed of Xu Cheng and his party was also greatly increased.

On the other side, Hong Nanlong was leading the soldiers of the second brigade to carry out an all-out counterattack, and from the red siren lights that suddenly appeared just now and various warning sounds, it was clear that a large number of alien troops were approaching here.

For this, Hong Nanlong is both happy and sad.

At present, the soldiers of the second brigade have injured more than 160 people, although the results they have achieved are unprecedented, as far as Hong Nanlong himself estimates, they have killed at least about 2,500 to 2,700 alien soldiers, it can be said that except for the last few hundred alien soldiers who are still resisting, the pit base is already the property of human beings to a certain extent.

"Hiss~~~! Hong Nam Long! Hong Nam Long! Hear the reply! Xu Cheng's voice came from the communicator: "We will sneak attack from the rear end of the alien race, remember that when I said that the fight began, the soldiers of the entire second brigade will rush up to eliminate these stubborn guys, don't spare the ammunition, we can use the equipment of the arsenal under the watchtower, please reply if you receive it!" ”

Hong Nanlong perked up and immediately replied: "Understood! We'll do that, but tell me, what's going on out there, and what's the sanctity of those alien forces rushing to their aid? ”

"A bunch of fourth-order, two fifth-order, and one sixth-order, plus three thousand elite alien soldiers... Go ahead and get ready, we're about to get started! Xu Cheng replied lightly.

Xu Cheng has already used his strength to feed at the moment, although this speed is too fast for the rest of the team, but the anxiety in his heart makes him unable to slow down the angle, one second faster here, and one second more time left for them to prepare.

Damn!!

Xu Cheng roared silently in his heart, and finally, after running around a corner, Xu Cheng said the word - "kill"!

As soon as Xu Cheng's voice fell, the soldiers of the second brigade over there tilted the small ammunition reserves that were already left like crazy!

The dense rain of bullets and the sudden rise in the momentum of the soldiers made the remaining aliens lose their fighting spirit in an instant.

Xu Cheng was like a Hellblood Demon God, slashing and slashing with a Regent Knife, and the heads of the alien soldiers around him were instantly cut off in a flash.

But what no one noticed was that Kalubu, the mastermind behind all this, chose to flee at this critical moment, and the strong strength and flying ability of the fifth order made his escape undetectable.

The pistol in Xu Cheng's hand had long run out of ammunition, and he was smashed into the skull of a poor worm on the way to his crazy fight, and that guy was also unlucky, so he was killed directly by a headshot.

These alien soldiers didn't last five minutes, and under the joint attack of Xu Cheng and the trial team members who came later and the elite soldiers of the second team, it didn't take long for them to die and escape, and at this point, the alien forces inside the mine base have been completely wiped out.

But this is far from enough, because the alien soldiers here are nothing more than a well-equipped bandit army to the upcoming elite army of the alien race, and compared to the combat effectiveness of their regular army, it is one heaven and one underground!

"Send someone to get weapons and ammunition in the tunnel, there should be transport vehicles inside the mining base that can be used, you can contact the people of the blocking team, they were rescued by us and taken to the scientific personnel in the central control room who are responsible for guarding the inside of the two mines there." Xu Cheng said lightly: "Go and pick someone, we can't delay for a minute!" ”

Hong Nanlong came like this, and he really got busy again without taking a breath.

"Zhang Jinyun, you and I go out to have a look, both of us can fly, faster, we have to observe in advance where the alien army that is coming is sacred!" Xu Cheng said and flew to the sky with Zhang Jinyun.

This layer can be flown out directly, and some places are reserved for cargo airships that come to load and unload ore, and at this moment, Xu Cheng and Zhang Jinyun are used as a passage to fly out.

Feeling the scenery of the outside world that they had not seen for a long time, Xu Cheng and Zhang Jinyun seemed to have washed away the bloody qi on their bodies in the airflow brought by the flight.

But soon, they were not comfortable, because not far from the pit, a huge army of aliens rushed in a long line, like a desert viper.

In the sky above this team, there was a conspicuous light group, Xu Cheng and Zhang Jinyun just looked at it like this, and they felt a faint pressure and danger, presumably the guy in the light group was a terrifying sixth-order powerhouse.

"Heh~~ Is it necessary for this guy to be so arrogant, the sixth order is not the ninth order, where did he have the courage to dare to march here so arrogantly?!" Zhang Jinyun said unconvinced: "With this kind of goods, I didn't even look at the young master before, but I couldn't imagine that now I would be threatened by him!" ”

"Hmph... We are now behind enemy lines, surrounded on all sides by foreign armies, what would he not dare to be arrogant? Xu Cheng sneered and said, "What's more, he is a sixth-order evolutionary body, and the most powerful on our side is only a fifth-order, so there will be no danger to him at all, of course he won't let go of this opportunity!" ”

"There are no heavy weapons, and the energy emitted as a whole is very powerful...... Xu Cheng muttered, "Shortcomings... What are the disadvantages ... There must be..."

But Zhang Jinyun said with some uneasiness at this time: "Can we retreat, that sixth-order alien race seems to have discovered our traces......

At this time, in the sky above the alien army in the distance, the sixth-order powerhouse of the alien race looked at the two small black dots suspended in the air in the distance, and the corners of his mouth were slightly upturned, but soon he was slightly stunned for a while, and turned his head to look at the other side, he seemed to see something.

"That's it... Kill these two little ones later, Terran...... It's really a race that deserves to be exterminated..."The sixth-order powerhouse retracted his momentum slightly, but immediately after, the light around him suddenly burst out like a volcanic eruption, making the surrounding space seem to be faintly oscillating!

Xu Cheng and Zhang Jinyun had already retreated, and at that moment, they felt that they were locked by that sixth-order powerhouse of the alien race, but after fleeing for a distance, they felt that this lock had dissipated again.

Just when Xu Cheng and Zhang Jinyun were puzzled, an unfamiliar voice came from the originally quiet communicator......

"This is the First Brigade, the First Brigade of the Ranger Army, the friendly troops received a reply, we are ordered by the military headquarters to come to support the second brigade to stop the alien forces and destroy the underground military factory hidden under the pit base!" An unfamiliar male voice said something that made Xu Cheng feel reassured.

"This is the Fifth Brigade of the Ranger Army, and it is also ordered to come to support, please reply if you receive it!" An unfamiliar female voice followed.

Xu Cheng took a deep breath, and the excitement in his heart was difficult to express in words at this time.

"Welcome... You're so welcome! Xu Cheng couldn't help but say: "If you don't come again, I'm afraid our entire second brigade will stay here today......

.......

Xu Cheng communicated with the captains of the first brigade and the fifth brigade about the current situation, and what made Xu Cheng feel a little difficult was that these two teams were far away from the pit base compared to the alien troops, of which the fifth brigade needed about twenty minutes to force the march here, and the first brigade took twenty-five minutes, so, to be honest, the last difficulty left for the second brigade and the trial team was to hold on for more than twenty minutes under the siege and attack of thousands of alien troops.

This is simply difficult for the second brigade, which now has only more than 400 people left and is seriously short of guns and ammunition!

Xu Cheng was silent for three full minutes, his heart was very entangled, because they would probably not be able to hold out before the arrival of the rescue force would be torn to pieces by the tide of alien troops.

Xu Cheng replied weakly: "Hurry, we must use the fastest speed, we can't last as long as twenty minutes.... Please...! ”

By returning the same way, Xu Cheng returned to the trial team, his heart was really hesitant, victory was clearly in sight, and the flame of hope had gradually ignited.

Looking at the soldiers of the second brigade beside him, Xu Cheng looked at these young people who were more energetic than him, and looked at the wounded on the ground, and the pain in his heart increased sharply!

What to do? Xu Cheng asked himself in his heart, as the supreme commander, he had no way at the moment.

But when he saw Xiahou Min, his heart flashed!

"Xiahou Min? Didn't you find an armored car in that arsenal before? What do you think of that thing? Xu Cheng asked expectantly: "The weapons there are very advanced, not worse than our equipment, if you can... The odds are stacked! ”

Xiahou Min nodded, but said suspiciously: "Why are you going to use it again?" Didn't you say ...... before"

"Hmph... It's all dying, why do you care so much?! Ah Qin sneered and said, "We can't fight with a burning stick, right?!" ”

Xiahou Min's mouth opened, but he still nodded with a wry smile.
