With the system's prompts, Chen Feng was even more careful.

The passage of the underground cave is only two meters wide, and one person can spread it, and it will feel awkward if the two of them walk side by side, so Mu Hang walked in front and Chen Feng followed behind.

Probably because there was too much movement on the ground just now, the two walked more than a hundred meters in the passage without encountering xenomorphs.

The only thing that made them feel unhappy was that there was no light source in the passage, it was completely pitch black, if it weren't for Chen Feng's keen instinct talent, he would have been blind when he came in.

As for why Mu Hang was able to see the surrounding situation clearly, Chen Feng didn't know.

Everyone has secrets, and there's no need to dig into them.

The talking range of the walkie-talkie is ten kilometers, but if it is underground, the signal will definitely be affected, so every time he walks, Mu Hang has to try to use the walkie-talkie to contact Zhao Kui to see if he can communicate normally.

If the signal is too influential, Mu Hang will have to consider whether to continue to go deeper.

After walking for about a few hundred meters, there was finally a rustling sound in the passage.

The sound of a xenomorph beetle!

Without waiting for Chen Feng to speak, Mu Hang reacted.

An arrow rushed forward, and the long knife brought a cold light in the darkness, and there was a popping sound.

An E-class xenomorph beetle that had just emerged was stabbed into the mouth with a long knife, and after a few struggles, the strong forelimbs finally failed to fall.

This was the first time Chen Feng had observed Mu Hang's battle up close, and he didn't have time on the ground just now.

It can be seen that Mu Hang's strength and agility surpass Chen Feng, but it shouldn't be very much.

As for the attack, it's hard to say for the time being, because Chen Feng has just changed to a top-notch weapon, and the attack increase is very obvious.

This E-class xenomorph beetle was just the beginning, and the howl of the xenomorph blood wolf could be heard from the depths of the passage!

There are even xenomorph blood wolves in the underground caves?

Could the skin demon be here too?

Really be careful.

Mu Hang also realized this, and said in a deep voice: "Be careful! Xenos are coming up! ”

As soon as the words fell, Chen Feng saw two xenomorph blood wolves rushing out side by side, their dark red eyes particularly dazzling in the dark.

"You're left, I'm right!"

Chen Feng took a step forward and stood with Mu Hang.

It's not that he's worried that Mu Hang won't be able to deal with two xenomorph blood wolves at the same time, but that he can't waste time.

There must be more xenomorphs behind the xenomorph blood wolf, once Mu Hang is entangled, it will be difficult for Chen Feng to exert all his combat power when he hides behind, and after a long time, Mu Hang will definitely not be able to support it first.

So even if he can't do it in the passage, Chen Feng must fight side by side with Mu Hang and share the pressure on Mu Hang.

Straight man pulls out the knife!

The cold light flashed, and the xenomorph blood wolf that had just jumped up was cut off by Chen Feng's head.

Mu Hang didn't have such a ferocious outburst as Chen Feng, the first knife seriously injured the xenomorph blood wolf, and the second knife killed it.

There was a noisy voice on the walkie-talkie, and Zhao Kui's tone was eager.

"Mr. Mu, there are a lot of xenomorphs rushing out of the other three caves, I'm afraid we won't be able to stop it!"

Mu Hang replied decisively: "Blow up the hole!" Stall! ”

Zhao Kui didn't reply, but soon there was a violent roar from the walkie-talkie, and the passage shook a few times, and even a lot of debris fell.

After three consecutive roars, Chen Feng knew that the other three underground cave exits had been destroyed, and now there was only one passage left to penetrate into the xenomorph lair.

Voices continued to come from the passage, and a large number of xenomorphs were rapidly approaching, and Mu Hang's face suddenly became serious.

Chen Feng silently clenched the heavy attack blade in his hand, and he also became nervous.

This kind of scene is also the first time he has encountered it.

Soon, a group of xenos rushed out, and Chen Feng and Mu Hang breathed a sigh of relief at the same time, because most of these xenos were F-level xenos.

Although there are also E-class xenomorphs, there are not many of them.

Chen Feng glanced at the xenos who rushed over, and then looked at the terrorist attack of 397-431 on the status bar, and the corners of his mouth rose slightly.

This scene seems to be very suitable for the more courageous play.

Soon, there was a hand-to-hand encounter.

The two long knives in Chen Feng and Mu Hang's hands kept flying, and each knife could accurately fall on the xenomorph's body, causing terrible damage.

Chen Feng relies on his powerful attacks and the damage that continues to be stacked as he fights, as long as he doesn't encounter E-level xenomorphs, he can guarantee a second kill with one sword.

Mu Hang's combat power is also powerful, and it can easily kill F-level xenomorphs in seconds.

But as time went by, two minutes later, there were more and more aliens who fell at the feet of Chen Feng and Mu Hang, and the state of the two also changed differently.

Although Mu Hang is a D-class ability with strong combat power, he is also a human being, and there are times when he is tired.

At the same time, in the face of so many xenomorph attacks, he has to deal with it with all his might, be cautious, and not be distracted, the consumption is extremely high, and after a long time, he will naturally feel powerless, and the direct manifestation is that his strength has decreased when he comes out of the knife, and sometimes he can't even kill F-level xenomorphs in seconds.

But Chen Feng became more and more energetic, one knife was faster than another, and his strength did not decrease in the slightest, maintaining the efficiency of one F-class xenomorph and two swords and one E-class xenomorph.

However, in the process, Chen Feng used another bottle of primary healing potion.

It was also at this time that Chen Feng truly realized the amazing role that the more brave and the more excited the battle could play, in a protracted war.

His stamina was only 96, and it stands to reason that Mu Hang was already showing fatigue, and he was not much better, but every time the long knife fell on the xenomorph, Chen Feng could clearly feel the recovery of his physical strength.

Although it is only a small part, it is very considerable.

When Mu Hang felt tired, he subconsciously paid attention to Chen Feng's situation, and was immediately frightened.

Why is this more and more exciting?

Don't young people know what it's like to be tired?

Mu Hang doesn't want to be old, but it doesn't seem to work.

Reality slaps in the face, snaps!

The battle continues, and there is a steady stream of xenos rushing out of the passages, seemingly inexhaustible, with no end in sight.

In this case, even Mu Hang began to wonder, can they still hold on?

Touching the C4 hanging from his waist, he silently made a decision in his heart, hold on for another three minutes, and if there is no end in sight, detonate the C4 and withdraw.

How many xenos had he and Chen Feng killed?

It's really a bit too much to count.

When fighting on the ground, the two of them joined forces to kill dozens of xenos, and when they entered the passage, they killed not a hundred.

But why is there still no intention of stopping?

Chen Feng is also paying attention to his state at all times, his health has always been above 80%, there is no danger, and the physical exertion is not very serious, so he should be able to continue fighting.

One more glance at the taskbar, only to realize that the task of destroying the xeno's nest was almost completed.

Kill F-Rank Xeno, 89/100, and Kill E-Rank Xeno, 23/30.

Unconsciously, there were already more than a hundred xenomorphs dead in Chen Feng's hands?

XP has also changed, 10760/12800.

Oops!

It's about to be upgraded again!

Seeing the experience points, Chen Feng suddenly felt energetic again.
