Reinforcements finally caught up, perhaps they had already learned about the situation from the black bear, or they may have been in contact with the veterinarian, and the two support armies carried a large number of communication beacons, which could keep in touch with the headquarters at a depth of 100 meters.

In addition to the communication beacons, they also carried a number of emergency lights that were only the size of a finger's belly, but extremely bright, to expel the darkness along the way, and the entire cave was brightly lit.

Fortunately, this is Mars, so you don't have to worry about the drastic changes in the ecological environment caused by the light - the Earth's cave environment is an alternative ecosystem independent of the surface ecosystem, and there are a large number of strange creatures living there, and the bright light is definitely a natural disaster nightmare for those creatures who have never seen light for countless generations since their ancestors.

But Mars is different, this cave is supposed to have been formed in the early days of Mars, when there was still a lot of water, but as the surface water of Mars slowly dispersed, the rivers dried up, the ocean disappeared, and the groundwater was not spared, and only a small amount of water froze under the formation.

Without water, the cave would no longer change and remained the same for millions of years until the arrival of humans.

Although there have been some cute fools who optimistically speculated that the Martian caverns may still contain native Martian microbes and even small creatures, they are undoubtedly mistaken, and thus become synonymous with fools.

While the bright light drove away the darkness, it also exposed the Outer Skeleton who was hiding in the darkness and peeping quietly, and under the light, the Outer Skeleton Man who took off his carapace was even paler, and the commandos mercilessly dealt a devastating blow to the Outer Skeleton.

Whatever is exposed, never let one go!

I don't know what Lu Dao is for, the two detachments that came to help followed Ye Fei's team very tacitly, without any intention of dominating the crowd, and the two detachment leaders also made it clear that when the task was issued, they were required to obey the assignment of the reinforcement troops.

The command is very thoughtful, the underground situation is unknown, rather than parachuting a commander with black eyes, it is better to let Ye Fei, a half-man, take the top first.

In terms of command, Ye Fei is purely a second knife with a bottle of less than half a bottle, but the second knife is always a little better than the new knife, right?

As for the so-called issue of military rank, in the eyes of the bigwigs in the command, is there a big difference between a second lieutenant and a lieutenant?

Faced with this situation, Ye Fei was obviously a little caught off guard, he didn't even understand his own birdmen, and he added more than twenty at once, and his mind was directly messed up.

Ye Fei, who was deeply self-aware, was very clear about his position, and politely asked the two detachments to guard the left and right wings in a consultative tone, and he himself walked in front with five people, which was a simple triangular formation, and he didn't ask anything about how the two detachment leaders commanded.

His original intention was just that he didn't feel that his ability was enough to command so many troops, so he simply became a shopkeeper, but this unintentional move won the favor of the two detachment captains.

Even if the superiors come to point fingers, the grassroots officers who serve as the detachment leader will faintly reject it in their hearts, let alone a detachment leader of the same level?

And he is a second lieutenant detachment leader, and he is still a second lieutenant who has just been promoted exceptionally, and the most outrageous thing is that the three detachments actually belong to three different divisions!

To go deeper, the two detachment captains have a basket of reasons to squeeze out Ye Fei, even if they don't dare to disobey the order and fight passively, it is inevitable that they have some ideas in their hearts, and now, everything has disappeared, and the three detachments are not only safe and sound, but also a little happy at first glance.

After all, the most difficult and dangerous task had already been completed by Ye Fei's detachment.

The reinforcements have also officially fought with the Outer Bone Man, and it is no problem to deal with the enemy in the dark, the speed of the team's progress is very fast, due to the low cost, a large number of emergency lights carried by the reinforcements are randomly placed on the route the team passes, except for a few shots from time to time, it feels as easy as an outing.

But few people are deceived by this illusion, everyone knows how the combat effectiveness of the outer bone people is, and the more outer bone people who have come out of their shells, the more unstable their hearts will be.

"There is a situation!" The scissors who were walking in front suddenly stopped, and their arms pointed forward into the darkness.

Ye Fei patted the monkey, and the monkey threw two emergency lights over without saying a word, and the emergency lights were activated on the ground, and the light suddenly shone brightly in the darkness.

The old blood vessels were still straight forward, but the translucent one that they encountered in the middle suddenly turned, revealing a large open space in front of them, and the dozen or so outer skeleton people stood on tiptoe on the high and low mountain rocks, as if they were stunned by the sudden accident, and they were stunned one by one, and they actually forgot to escape.

Ye Fei was also a little stunned, but he was stunned by these dozen outer bone mongrels with a full set of carapaces on their bodies!

He thought that all the outer skeletons that had gone underground had come out of their shells.

Ye Fei was stunned, but the reinforcements felt that the outer bone talent that had come out of the shell was strange, and when he saw the outer bone person he was familiar with, he didn't say a word, and he didn't need to think through his brain, and his finger directly pulled the trigger.

The sudden explosion of gunfire woke up both the enemy and us, and the outer skeleton was like a frightened grasshopper, jumping away, but half of them had already been killed by the indiscriminate shooting.

The escaped Outer Skeleton Man immediately returned the color, and more than a dozen corrosive balls were thrown at the same time, and the black bear, which had replenished a large amount of ammunition, sprinkled a rain of bullets all over the sky, and exploded more than half of the corrosive balls in the air.

The commandos were no better than the Skeleton Man, fleeing like frightened sheep, looking for cover.

The ground of the cave was uneven, and so was the passage between the two blood vessels, but the distance between everyone was too close, and in such a short distance, there was no cover for enough thirty commandos to hide, and there was a depression under the blood vessels that was the size of a foxhole and filled with water.

Thankfully, the Outer Skeleton hurriedly fought back, and the corrosive ball thrown over him was not accurate, which caused casualties, and only one of the team members had a little acid splashed on their armor.

"Spread out, spread out!"

"Attack, attack!" The two detachment leaders were shouting hysterically, and the commandos who found the bunker immediately suppressed the enemy with the strongest firepower, and those who couldn't find the bunker were able to squeeze with their teammates, and those who couldn't find it ran back.

The firepower of the commando team is amazing, there are three Gatling alone, and the environment of the cave is relatively closed, so there is not much room for escape or dodge.

The Outer Skeleton Man will not escape death as long as he rises to the top, but the corrosive balls are throwing weapons like grenades, and there is no need to aim in a straight line at all, although the team members have used their firepower advantage to the limit, they still can't guarantee to stop all the corrosive balls, and one corrosive ball happens to hit the head of one of the commandos, the acid covers half of the upper body, and the armor corrodes at a speed visible to the naked eye.
