So their attention, at the moment of the change, is focused on the area they are in.

And this is Xu Hu's chance!

Xu Hu no longer hesitated, and quickly climbed up along the wall.

In less than 10 seconds, Xu Hu climbed over the wall and saw the situation inside the wall.

In the nearly 1,000-square-meter wall, there is only one passage at the intersection of the tunnel.

The armed defense was so tightly guarded that it was just to guard a passage.

This not only made Xu Hu very curious, what kind of secrets exist under this passage.

However, this time is not the time for Xu Hu to be curious, and at the sentry post 10 meters away from Xu Hu, the 6 sentries have been handed over.

Three new sentries have taken up their posts, and one of them is patrolling over to Xu Hu.

Now all Xu Hu has to do is to quickly change his position, otherwise he will be discovered by the sentry and put in danger.

Immediately, Xu Hu's gaze swept around, and quickly locked on a few dark areas, which were places where the lights were very weak, that is, the legendary lights were dark.

Xu Hu also notices clearly that there are two points of fire in the area directly below him that the light does not shine.

Twitching his nose slightly, Xu Hu clearly felt the smell of cigarette smoke.

It looks like there are GIs smoking cigarettes down there!

Xu Hu's eyes suddenly narrowed slightly, and the sentry closest to Xu Hu at this time was already less than 6 meters away from Xu Hu.

Immediately, Xu Hu no longer hesitated, directly climbed over the wall, jumped down the wall, and threw himself into the darkness.

At the moment of plunging into the darkness, Xu Hu took out the short knife tied to his leg and rushed straight towards the two points of fire in the darkness.

"Poof!"

There were two slight sounds, and Xu Hu clearly felt that there was liquid sliding between his palms.

Xu Hu knew that this was the feeling of blood sliding across the palm of his hand.

In the darkness, Xu Hu faintly saw that the two stared at him, full of disbelief, staring at him.

Xu Hu grabbed a person in one hand and gently put the two in the dark.

Xu Hu knew that he didn't have much time left.

There are 50 minutes to go!

If he can't find Philos within 50 minutes, then his plan a has failed.

Then he'll have to activate Plan B!

Against the clock!

is talking about Xu Hu's current situation.

After dealing with the two more GIs who were smoking in the dark, Xu Hu set his eyes on the gate of the tunnel.

That's where Xu Hu needs to overcome difficulties!

At the entrance of the tunnel, a large number of sandbags were piled up, and two machine guns, which were not available in the outside world, were facing the outside.

These two machine guns Xu Hu knew, and they were the famous Gatling machine guns in later generations.

Don't ask where Xu Hu met, I learned about it in the black-hearted game of a black-hearted penguin in the legend.

It may be that the defense of Area 51 is too tight, so that some of the soldiers on duty in Area 51 have relaxed their vigilance over time.

For example, two GIs behind the sandbag pile were chatting boredly.

Even Xu Hu, who was hiding in the dark, could hear the meat jokes spoken by the two soldiers.

"It's better for you to let your guard down, how can I act cheaply." Xu Hu whispered quietly.

He had already observed his surroundings just now, and the other GIs would only pass through this area at a fairly regular time.

And in this regular time, there is a blank time, which is Xu Hu's opportunity.

In the next second, Xu Hu moved again.

The blank time had temporarily arrived, and the nearby GIs had already walked away, except for two GIs who were bragging about cowhides behind the sandbag fortifications.

The two GIs who were blowing cowhides only felt a strong wind blowing in their faces.

Facing the soldier in Xu Hu's direction, his pupils couldn't help shrinking, and he saw a figure approaching them quickly.

As far as he knew, that kind of speed was only possessed by the deepest part of Area 51, the genetic warriors who were researching.

Could it be that those genetic warriors have escaped? The GI thought in horror.

But that was the end of his thoughts.

At this time, Xu Hu was already holding a bow and crossbow, and shot out two short crossbows, which shot into the necks of the two soldiers respectively.

Xu Hu's shooting position was very clever, just where the two of them hit the throat.

The two of them couldn't make any sound, so they collapsed to the ground softly, and could only desperately grasp the short crossbow on their necks with their hands.

After Xu Hu finished dealing with these two people, he didn't look at these two people, and walked deeper into the base.

Less than 300 meters away, there is a rather large elevator.

Xu Hu didn't expect that there would already be an elevator in this era.

Was it because the Rice Free Federation had developed an elevator during this period, or because this world was a movie world? Xu Hu thought curiously.

Fortunately, there was no need to enter any password in this elevator, and Xu Hu went straight into the elevator.

There are floor signs in the elevator, which is very rigorous and scientific.

The first 30 underground floors are all about military weapons research, which are related to land, sea and air.

The last 15 floors are dedicated to aerospace research.

The next 5 floors are just about the study of the occult realm.

The last one is related to genetic engineering, and it has only a short name, Biochemical Research Institute.

Thinking about the medicine that the protagonist Philos is good at, Xu Hu did not hesitate to lock his eyes on the last layer, the 51st floor of the Biochemical Research Institute.

In the next second, Xu Hu pressed the case that went to the Institute of Biochemistry.

The whole elevator suddenly moved slowly, and then became faster.

Xu Hu clearly saw that the elevator floor was changing rapidly, and he was soon approaching the 51st floor.

However, when he was about to reach the 51st floor, Xu Hu's complexion changed drastically.

He saw that in the back right corner of the elevator, there was a device similar to a modern camera facing the elevator.

He couldn't have put his hopes on the possibility that this camera-like device wouldn't be usable.

Xu Hu knew that his plan A had failed.

Then Xu Hu took a deep breath, fortunately, he still had a backup plan!

Suddenly, there was a crisp sound, which was the sound of reaching a designated floor, similar to the sound that some advanced elevators now remember when they reach a floor.

"Ding!"

The elevator door slowly opened, and looking at the scene outside the elevator, the corners of Xu Hu's mouth twitched.

As it stands, Plan B is no longer used.

However, in order to add to the authenticity of Plan B, Xu Hu also needs to risk his own strength.

The moment the elevator slowly opened, Xu Hu saw it.

Outside the elevator, there were three squads, heavily armed soldiers, holding guns at the elevator entrance.

"Why is there such a thing as filming equipment in this era? And is the technology used in the elevator so advanced? ”
