"I was thinking, this should be the prompt given by the system!"

Feng Luo pointed to the corridor on the opposite side, which was mostly covered by sand. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"Huh? Is this a hint! ”

Burn and run a little confused.

"On the screen of the scout just now, the crawling route of those monsters is not a straight line or a curve, but there are some broken lines in the middle, which looks like they are crawling up on some devices like stairs!"

"And the depth of their position shown on the recon scale is more than thirty meters, which is more than the theoretical height of this sand dune from the ground!"

Fengluo nodded.

"Brother Feng, what do you mean?"

Mr. Jiao's eyes lit up all of a sudden.

"As a military base, there is definitely not only the surface part, but most military bases will build an underground part, and even because of safety reasons, the underground part of the building will be more important than the aboveground, and it will be more difficult to destroy!"

"And the A-2 experimental base we need to find is also an underground experimental base!"

Fengluo spoke his judgment.

"Huh? So that's it! ”

The group all understood the meaning of Fengluo.

"But Brother Feng, how do you know how high the ground is, and why didn't those monsters just stay in the building just now?"

However, it is still a little puzzling to burn and run.

"The reason for the formation of this sand dune is probably because the wall around the military base is blocking the sand. From there, you can estimate the approximate location of the ground at the original base! ”

Fengluo replied.

"Dizzy, you can still calculate and infer like this! Brother Feng, did you think of so much at once just now? ”

If you burn it, you will run, and this time it is served.

"Perhaps, it's the reason for evolution!"

Fengluo smiled.

"The downstairs on the opposite side should be the underground part that leads directly to this military base, and inside, you should be able to find things related to the A-2 experimental base."

"So, my opinion is that let's go underground through that building first!"

There is no opposition to the wind falling.

For Fengluo's inference just now, everyone thinks it makes sense.

However, when I got to the front of the building, I ran into another problem.

Although it is not completely covered, there is a lot of sand in the building, and you have to dig up a lot of sand to get in.

This is a very troublesome matter, and after more than ten minutes, I have not been able to dig into it to a depth of two meters.

"Call your pet out to help!"

Thorn Rose spoke.

"yes, I forgot about that!"

Everyone was a little speechless, they didn't even think of this.

In the battle these days, because the level of the monsters faced is really too high, it is inconvenient for your pet to take it out to participate in the battle.

But now it's not a fight, it's a sand digging, and pets are naturally a good labor!

"Boom, boom, boom, boom......"

Continuous white light flashed, and seven pets of different types appeared on the sand dunes!

As for the other two people who didn't summon pets, it was because the pets were too small to be suitable for this kind of work.

In addition, the wind has fallen.

24K is now unconscious, otherwise, he only needs to summon the collection beetle "Unification", and it will take a minute at most to open this path.

However, one of the pets in the group is very good at making holes in the sand.

Adele's pet turned out to be a snake, a desert golden rattlesnake with almost the same color as the sand and a length of more than seven meters!

This kind of snake wind is more familiar, because the previous time in the arena with the phoenix and the big pineapple "three black", one of the five people opposite the pet is a desert golden rattlesnake!

It's just that the level of that rattlesnake is the commander level, and Adai is obviously just an elite-level pet!

Fortunately, the elite level is also enough.

With the addition of this native pet in the desert, the process of digging sand has become much easier!

……

Half an hour later, the group was already standing on the lowest floor of the building, looking with excitement at the huge passage that appeared under the lighting equipment!

"Brother Feng, you're really convinced by your observation!"

Boss Meng is putting armor on his body one by one.

No one could call him too fat, and the holes he dug weren't big enough, so he had to take off his armor to get in.

The situation is just as judged by the same wind fall, the bottom of this building is directly connected to the underground base, and this kind of underground building will obviously not be affected too much by the sand.

Inside, you can look for information about the location of the A-2 experimental base.

Of course, before that, there is a little bit of a problem that needs to be solved!

"Squeak, squeak!"

A mutated mongoose with orange eyes in the dark is speeding towards this side from the underground passage, roaring angrily!

Of course, these levels are only thirty or forty, or even a dozen mutant mongoose cubs.

Impossible, a real threat to a group.

After solving the last little trouble of entering the underground base, Fengluo and his party successfully entered the base!

At this time, the sky outside had completely darkened.

Of course, although the sky is dark, the entire Death Desert has not lost its color!

Because the Death Desert is rich in a kind of sand and gravel containing a special mineral, the surface of the entire desert has been glowed with a faint red light, providing a vision for countless nocturnal creatures.

In the deepest part of the Desert of Death, the maximum temperature on the ground during the day can reach more than 70 degrees.

This kind of temperature is difficult to withstand even for desert creatures that are resistant to high temperatures.

Therefore, most animals only start to move and hunt at night, especially in the evening.

And after the wind fell on their front feet and entered the base.

A minute later, in the sky, a huge black-purple eagle with a wingspan of more than ten meters suddenly fell from the sky!

The wind brought by a pair of giant wings shook the vast desert, revealing the corpses of dozens of mutant mongooses on the ground whose blood had dried up quickly due to the heat.

Then, it stretched its neck and swallowed it one by one.

If Muzi's scout instrument was still in range at this time, he would definitely call the police frantically, and there would be a blood red representing boss-level creatures on it.

Purple Blood Falcon, level 70 quasi-BOSS!

There was no doubt that if the wind fell they were one step slower to enter the underground passage.

At this time, ten humans will be added to the food of this powerful quasi-boss.

Although you can defeat a level 70 boss monster, if you are facing a quasi-boss who is only one level higher!

Even if there are ten more people, there is almost no chance of winning!
