Erdan's gaze is fixed on the top of the toilet cubicle baffle, which can stand on people, two meters high, and can gain high speed when jumping from above and falling to the ground.

If you do this, it is a bit dangerous, and if you can't wear it, you will definitely fall and break your head and bleed.

In the current situation, Erdan has no extra options, and every possible method must be tried. Escaping is not the second egg's style of doing things.

Erdan stood up, held on to the top of the baffle, kicked the ground with both feet, supported his arms hard, and turned over, and the person stood on it.

The baffle that compresses the sawdust is not too strong, and the weight of the second egg is very heavy, and the baffle is a little dangling.

The dilapidated house happened to rain overnight, and when the second egg was anxious, there were footsteps outside, and it was very likely that he came to the toilet.

Erdan hurriedly moved, his anger sank into the dantian, this time he lifted more qi, and the speed of flow was faster, and then he held his breath and concentrated, and after a few seconds, his body entered a semi-trance state. The second egg didn't dare to hesitate and jumped. If you can pass through it, you can leave it to God, no, it's not God, there is no God in Area 51, so leave it to Marx! After all, Marx was a pioneer of science, and the entire Area 51 was a scientific experimental base.

With a bang, the door of the toilet was pushed open, and sure enough, someone came to the toilet, it was a half-centenarian man in uniform, with a lot of medals pinned to his chest, probably a veteran of the battlefield!

The veteran of the battlefield thought that his eyes were dazzled, and in his confusion, he seemed to see a shadow burrowing into the ground. The veteran rubbed his eyes, took a few steps forward, and squatted on the ground that the shadow "drilled" into.

"Oh my God, I must have been wrong." The battlefield veteran muttered to himself.

This time, the second egg successfully passed through.

At this moment, the second basement floor, a laboratory. Above this laboratory is the toilet where Erdan was just now. In the laboratory, there are four researchers in white coats who are busy, some are manipulating instruments, some are recording parameters, and some are pouring bottles and cans. Everyone was very attentive and communicated with each other occasionally. When a figure fell from the top floor at high speed, no one noticed.

When Erdan's head fell to the negative floor underground, he didn't stay, and went straight through it again.

It's important to mention that wall piercing isn't about going through one wall at a time. At that time, the yoga master of the Three Kingdoms was ready to wear three walls with a thickness of half a meter, but unfortunately the Tao was not enough, and only penetrated the first two pieces in a row, and when he wore the third piece, the mana disappeared or was not enough, and he was stuck alive in the third wall.

Erdan was lucky, because he was not found when he penetrated to the negative layer underground, and he penetrated the ground of the negative layer directly.

Now the second egg is on the second basement floor. This floor corresponds to the toilet on the upper floor with a walkway.

Erdan is very lucky, if it is not a walkway, but a load-bearing wall, the height of seven or eight meters is the thickness of Erdan, and it is strange if it is not stuck in it.

The walkway was quiet, only two people were walking, and they had crossed the spot with their backs to Erdan.

A dark shadow appeared, and the speed was amazing. The second egg is no different from doing a free fall exercise now. There are three underground levels of the fortress, each of which is eight meters high. According to the formula of free fall, the speed at which the second egg falls to the negative second floor underground, an astonishing speed.

Ah San's yoga master can penetrate two walls, will the second egg be worse than him? Joke! It's definitely better than him, and it's not a little bit like that.

On the ground of the second basement floor, the second egg was still in a trance when he fell here. It is worth mentioning that the mental semi-trance state will have a strong impact on the physical body, which may be the spiritual power of that divine horse. And the physical body, under the influence of spiritual power, will be in a special state. As for the state of Shenma, it is not impossible to create a new field of research in the future.

The subconscious told Erdan: Brother, keep up the good work, you can pass through this layer, but I can't guarantee the next wall.

Without any suspense, Erdan passed through the ground of the negative second underground floor at high speed, that is, the zenith of the negative third underground floor.

There are cameras in the corridor on the second basement floor, but there are thousands of cameras in the entire base, and the speed of the second egg is so fast, unless the monitoring personnel keep staring at the picture of this camera, they don't want to find that there is a "foreign object".

The underground fortress of the base has a total of three floors, and then below is the mud mortar rock god, and then below is the center of the earth, if the second egg can still pass through, it is not allowed to appear somewhere in our Huaxia. This is absolutely impossible.

When Erdan penetrated to the negative third floor underground, his consciousness immediately recovered, and he felt that he was suddenly poured a basin of cold water from a trance.

With such a fast speed and such a hard ground, if you hit your head in a daze, your head will definitely shrink into your neck.

Erdan's consciousness regained and he immediately moved, volleyed a heel, moved his body sideways, and landed on a table.

Bang, there was a loud bang, the wooden table was smashed, and Erdan felt that his bones were about to shatter.

Malegobi's, why does it hurt so much!!

This little injury is not in the way, because Erdan's body has a self-healing ability that is different from ordinary people, and wounds that are not too fatal can heal automatically.

Erdan stumbled out of the pile of wood chips, and before he could take a closer look at what the hell this place was, he suddenly felt very cold.

Erdan looked around and gasped, it was really cool, the temperature in the house was much colder than outside.

Could it be an underground storage room, something like an ice cellar?

This is not true, if it is an ice cellar, it will definitely be colder, and it will even freeze.

Where does the air conditioner come from?

The house is not very large, ten meters long and five meters wide, with white walls, white floor tiles, and a white ceiling. There are several cabinets against the wall, and you can't see what's inside. In the middle of the room was a metal iron bed resembling an operating table, which was empty and empty.

The gaze of the last two eggs was fixed on a "wall". This is not an ordinary "wall", the wall is glass, green glass, very thick, according to the shadows that appear on the wall embedded in the corners, it is also 30 centimeters thick. There is also an enclosed space within the glass walls, where the cold air is steaming.

The glass wall that Erdan saw was actually a "window", more than one meter in diameter, and the door was next to it. The door is also very domineering, similar to a bank vault, with thickened steel plates and a handle that resembles a vehicle's steering wheel.
