Mu Anran still had something to do, so Chen Feng naturally wouldn't take her to the xenomorph lair at this time.

What's more, Mu Anran is still injured, and he is not in the right state and is not suitable for fighting.

Coming to the vicinity of the xenomorph nest with ease, Chen Feng found that the number of xenos around him had decreased significantly.

Although there are still many xenos in the tulou, elite xenos or xenomorph leaders are rare.

Chen Feng didn't have any intention of dodging or making a detour, and directly broke in.

However, the expected scene of the xenomorph attack did not appear, but the xenos fled one after another after discovering Chen Feng, and did not dare to fight Chen Feng at all.

Chen Feng was stunned for a moment, the xenomorph even knew that he was afraid?

This doesn't make sense!

Chen Feng gave Lu Yun a look, and Lu Yun took the initiative to rush out, but the nearby aliens did not run away again, but launched an attack on Lu Yun.

Lu Yun is also a strong player among C-level aliens, and it is still very easy to deal with ordinary aliens, even if he encounters D-level elite aliens or D-level alien leaders, he has a great chance of winning.

In just a few minutes, dozens of xenos were killed, and the corpses were stacked, but the xenos did not retreat at all.

When Chen Feng walked forward, the xenos who were besieging Lu Yun suddenly retreated, not daring to fight.

Chen Feng frowned, the xenomorphs had this reaction, could it be that in this xenomorph lair, there was a powerful existence similar to the xenomorph slave warrior lord, commanding them?

There are eighteen caves around the tulou, and according to Chen Feng's experience, these eighteen caves should be connected.

The number of xenos attacking the survivor base has reached 10,000, except for the earth building and the almost 2,000 on the ground, the rest should be in the underground cavern.

Even if you attack the survivor base today, there will be a lot of losses from xenos, but it is conservatively estimated that the number of xenos in the underground cavern will exceed six thousand!

Six thousand xenospecies!

It's exciting to think about!

This is not xenogeneous!

It's all walking experience and merit points!

Chen Feng glanced back at Lu Yun and said, "Follow me, if you can't hold on, speak in advance." ”

Lu Yun nodded, silently clenched the bone crusher hammer in his hand, and prepared to fight.

Chen Feng did not rush into the underground cave, but entered the tulou and cleaned up the xenos he could see first.

Chen Feng's current attributes are very rebellious, and in the state of no buff, the attack has even reached 6240-6385, even if the D-level alien comes, it can be easily killed in seconds.

Only when encountering elite xenos or xenomorph leaders is it worth Chen Feng's extra cuts.

As the battle progressed, the buffs that became more and more courageous were stacked, and even the elite xenos and xenomorph bosses became vulnerable.

However, after Chen Feng killed two D-class xenomorph leaders in a row, the xenos in the tulou actually began to escape, and the speed was so fast that even Chen Feng had no choice.

In less than two minutes, the xenos in the tulou disappeared, and Chen Feng could only take Lu Yun to the entrance of the underground cave.

There were also seventeen cave entrances around, if it was before, Chen Feng would definitely not enter it easily, but now it was different.

Chen Feng felt that he was already strong enough to deal with all kinds of situations in the xenomorph lair, even if he encountered the xenomorph slave warrior lord or the xenomorph slave wolf knight lord again, he would encounter the power of a battle.

So, why not go?

What's more, the system clearly issued a mission, which requires going deep into the xenomorph lair and killing the xenos lurking inside.

For the sake of the task, Chen Feng also had to go in and take a look.

The underground cave is very dark, Chen Feng's combat power has reached Level B, his ears and eyes are clear, and with his keen and intuitive talent, he can easily see the surrounding situation.

Lu Yun's combat power was not as strong as Chen Feng's, and he could only barely see the situation in the dark.

After entering the underground cave, Chen Feng did not encounter the attack of the xenomorphs, probably because the powerful xenos in the xenomorph lair had already given an order not to let the ordinary xenos come and send them to death.

Chen Feng didn't care either, his target was not these ordinary xenomorphs.

As long as he can kill the powerful xenos hidden inside, the rest of the xenos will not be slaughtered by him?

It's a pity that without an ordinary xenomorph attack, the buff that becomes more and more courageous cannot be stacked, but it will affect Chen Feng's performance to a certain extent.

Continuing to go deeper, after walking for more than three hundred meters, Chen Feng finally heard movement in the passage, and the system's prompt also sounded at this time.

Bite!

Trigger Mission: Destroy the Xenocore!

Content: The Xenocore contains very terrifying energy, which will not only give a combat power bonus to nearby Xenos, but also increase the strength of Xenos and help them break through the shackles.

Rewards: 30,000 base experience, small xenocores.

It's a mission again!

And it also involves the xenocore.

Chen Feng seemed to understand why the xenos on the ground had to run into the underground caves, because being close to the xenomorph core would increase their combat power!

The exact amount of improvement will not be known until you see the xenomorphs.

The voices in the passage got closer, and a group of E-class xenos rushed out.

Chen Feng hurriedly gathered his gaze to observe, and found that the attack, defense, and life attributes of the xenomorph had all increased by 20-30%!

This level of improvement is already terrifying!

The title of Heavenly Chosen One that Chen Feng had just obtained was only a 25% increase in four-dimensional attributes.

The improvement brought by the xenocore can almost catch up with the effect of the title of the Chosen One.

Chen Feng grabbed the handle of the knife, reminded Lu Yun, and took the initiative to rush forward.

E-level xenomorphs are E-level xenomorphs after all, although their combat power has been improved, but the foundation is really too poor, and when they meet Chen Feng, they are still the result of being killed in seconds.

Lu Yun followed behind Chen Feng, and almost couldn't get a chance to make a move.

Soon, the first wave of attacking xenos were all killed by Chen Feng, and the more they fought, the more courageous they became, they were stacked to the 53rd floor.

There was another voice in the passage, and the steps were heavier than before.

Chen Feng did not hesitate, and took the initiative to accelerate and rush forward.

If it's slow, the more you fight, the more courageous the buff may disappear.

This time, they were all D-class xenos.

The blood volume of D-level xenomorphs is generally around 2000, and after getting the blessing of the xenomorph core, the blood volume is around 2500 to 3500, but it still can't withstand Chen Feng's knife, and he can't get rid of the fate of being killed in seconds.

The battle came and ended quickly.

Fifty D-class xenomorphs only lasted less than three minutes, and Chen Feng's blood volume was still full.

The 3% vampir brought by Bloodlust is very suitable for protracted battles.

This time, there was no movement in the passage, and Chen Feng sighed as he looked at the battle that had been stacked to a hundred layers.

It's a pity.

Let's deal with the corpses of D-class xenos first.

Fifty D-class xenomorphs are fifty copies of D-class xenomorph blood.

Make it into a D-class enhancement potion and sell it again, which is 60,000 merit points.

Thinking like this, Chen Feng's heart suddenly felt comfortable, and he hoped that the xenomorph in the depths of the cave would quickly send some D-class xenomorphs over.
