The entrance to the underground was in one of the deepest branch passages in Passage Four, closer to the one they had explored when they first came here, and the entire passage was about three kilometers long, all of which were cast from special metals.

Walking through the passage, the darkness did not cause any trouble to Mu Tolerance, and he returned to Passage Four at great speed.

After careful consideration, he finally chose to believe David's words.

David is a robot, although his behavior feels a little weird, but the other party is not a drifter after all, he doesn't know so many things, and he doesn't have any purpose from beginning to end.

Moreover, even if David really set a trap, now Mu Yan has to drill it, because if there is no further breakthrough in the mission here, then all his efforts for more than ten hours will be in vain.

On the way from Passage 4 to Passage 3, it took about thirty minutes, but the closer he got to the target location, the more he felt that something was wrong!

It's so quiet! Along the way, both the fourth and third passages are too quiet!

Ever since he killed Hanek and separated from David, he had been searching for an entrance to the underground, and the obstacles he encountered along the way were almost constant, and those very annoying worm aliens were almost everywhere he went, and finally he was tolerated to the point of running when he saw them.

And now that I'm back here, the worm aliens that were supposed to be there are gone.

The end of passage three was in sight, but there was no sound here except the sound he made as he walked, as if all the sounds on the planet were imprisoned, and only his feet could make sounds.

"What's going on? Could it be that the worm aliens left when I wasn't looking? Or is it because of the departure of Gao Chenke and others, the difficulty has been reduced, and those nasty little things have died with it? ”

Just as Mu Yan was walking and cautiously guessing, a burnt smell suddenly came into his nostrils.

"It's here!"

Shaking his head to shake off what had just bothered him, he ran quickly, and in the blink of an eye he was in a charred ruin.

Since the bullet fired from the telekinetic pistol was a bullet with explosive and incendiary surnames, everything in the entire alien lair was destroyed. However, within the destroyed ruins, there is something very conspicuous today.

On the ground, David was like a dismantled puppet, his body had been shattered, his head, arms, legs, and body had all been dismembered everywhere, and there was even a lot of dried white liquid left on the ground.

"Really dead?"

Approaching David's corpse, Mu Yan's eyes did not reveal the slightest emotion, don't say that the corpse in front of him is not human, even if it is a real human, he will not feel anything, the most important thing is to be able to help himself.

"The chip David said should be in this brain, right?" After muttering to himself, he stretched out his hand casually, and then his entire arm was suddenly covered with a layer of black substance, which became very long like a rubber band, and suddenly grabbed David's golden hair, and the arm was tugged again, and the suddenly stretched arm recovered instantly, and the black substance disappeared.

For more than ten hours, Mu Tolerance was not only looking for clues to the second mission, but more importantly, he was constantly developing other functions of the Life Armor, and being able to extend his arm was one of them.

David's head was grabbed in his hand, Mu Yan didn't care whether the other party was really dead or had no energy, and after he grabbed it in his hand, he directly grabbed the skin of the skull's face, revealing the metal bones inside and some white liquid that did not flow out.

The metal in David's body was not very hard, but there were many solder joints, which were like a spherical piece of iron, and in the end, he could only tear off all the skin of this skull, and even the hair was left.

No way, Mu Yan is not a human being in this era, and he doesn't understand the technology here, so there are some things that he must use simply and crudely to get results.

Sure enough, at the end of the dismantling, he found a chip in the back of David's skull, about the size of a baby's palm, even if it was contaminated with white liquid, it still looked so high-end and high-grade.

But after disassembling the chip, he took the chip and made it difficult .......

"This thing...... How to use it? ”

Just when Mu Tolerance was in trouble because of how to use the chip, two scarlet cold rays suddenly appeared in the crack between the third passage and the second passage, and the two cold rays were murderous, cold and ruthless, and they were a pair of eyes.

"Huh!"

Just when Mu Rong didn't pay attention, a tentacle covered with black spots suddenly appeared in the crack of the black monster's mouth, and the tentacle writhed in mid-air like a snake in the water, bringing bursts of air fluctuations, and the air flow also twisted, making a sound of breaking the air, and swept towards Mu Rong.

Almost at the same time as the sound appeared, Mu Yan felt a shock in his heart, and then before he could react, he felt a powerful force suddenly coming from his back, this power and even kinetic energy absorption and life armor could not be absorbed, it was directly transmitted to his body, a stream of blood surged up from his throat, and the feeling of severe pain spread all over his body!

"Damn! Sneak attacked! Damn David! Mu Rong's face was hideously pressed against the blood in his throat, and David's face appeared in his mind the moment after he was attacked. At the same time, the X mutant gene in the heart immediately took action, desperately releasing kinetic energy to soothe the irritable attack power in the body, and desperately absorbing the impact of this power.

The tentacles shrank back into the black crack as soon as they hit him, but the pair of ice eyes were still filled with scarlet light.

"Whew!"

After being attacked by the tentacle, Mu Yan staggered forward a few steps, and then immediately escaped from the telekinetic pistol, and repeatedly pulled the trigger behind him.

"Woohoo......!"

"Boom ......!"

In the explosion, the crack that was originally pitch black exploded, and then the fire was raging, and the culprit who was hiding in the dark and sneaking up on Mu Rong was also reflected in the firelight, it was a huge figure!

"It's the tentacle alien in the lab...... How can it be! Why didn't the Life Armor warn at such a close distance? ”

"Roar!"

The huge body explosion bullet of the alien hit but did not do any harm at all, but it felt the burning under the flames and roared angrily, and with this roar, it once again threw out the tentacle that had just sneaked up on Mu Yan, and rushed straight like a thick python.

Mu Tolerance didn't expect that he was attacked and didn't have time to scream, but the other party called first, and the huge roar shook him dizzy in this environment.

"Roar Nima!"

This time, the life armor sensed that the host was threatened, and in the blink of an eye, it covered all of Mu Yan, making his whole person suddenly rise as if he had grown several laps of figure out of thin air, and the burly man was like a strong man. At the same time, the two arms with the thickness of the thighs of ordinary people spread out from behind their backs like wings, looking like a demon in the night.

A touch of space ring, a strong fusion gun, a Gauss pistol, and an ordinary Woods submachine gun appeared on the four hands in an instant, pulling the trigger together against the crack!

The roar of the original alien just now had not been extinguished, and an even more violent roar descended on the place again.

In an instant, the explosion of the bursting bullet, the humming of the brewing plasma of the melting gun, the screeching sound of the Gauss pistol piercing the air, and the continuous roar of the submachine gun, the sound of the four guns resounded throughout the passage like an ensemble, with a mixture of red, yellow and blue!
