Because of the chaos of this month, the two have not been able to remember exactly the time in the past.

I just think that the end of the month is coming.

So Herman began to cut the PVC pipe of the pool.

After repeated measurements, the two finally left a space for their heads in the sewer pipe.

Then the two began to plan an escape plan.

"I personally feel that the anesthetic gas will stop after a period of release."

Lin An said, "Then transfer our staff will come in." ”

The two stood in front of the pit, pointing.

"We'll be lying on the edge of the pit then, after all, for such a place,

It's also normal for people to be here. Herman said.

Lin An lay on the edge of the pit, and Herman stood beside him and continued.

"As soon as the staff came, we pushed them into the pit."

Lin An lay on the ground and grabbed Herman's feet.

Herman nodded when he saw it and said, "That's right,

Directly let them lose their balance, and there is no chance to resist at all. ”

Then the two came to the water pipe, and Lin An now put his head under the pool.

Hold the drain pipe in your mouth and try to catch your breath.

A violent stench rushed to his brain, causing him to immediately raise his head and cough.

Herman tentatively sniffed close to the pipe.

"We had to get used to the smell." Herman said.

Lin An coughed and nodded.

Later, Lin An kept drinking tap water.

Herman took over him, reaching out for a piece of meat.

Lin An looked at the piece of meat.

He slowly picked up the meat and put it in his mouth, then drank a lot of water.

As the rapidly moving tunnel crossed the level, the two knew that it was night.

"Maybe it's just tonight." Lin An said, sitting next to the pool.

Unable to remember the exact date, the two sat by the pool and slept every night.

Just when the two of them sat by the pool and fell asleep.

Suddenly, the light that had been white turned a dull red.

The two looked at each other and immediately took a deep breath.

Sure enough, the anesthetic gas began to be released.

Lin An and Herman counted the time in their hearts as agreed before.

The two took turns holding their breath for one minute at a time, breathing in the tube for a while.

They are all waiting for the anesthetic gas to stop.

Just fifteen minutes passed slowly, and the gas showed no sign of stopping at all.

The two didn't communicate much, just kept breathing gas back and forth in the sewer.

Suddenly, the whole prison pit actually sounded on the radio-

"Please note that the staff will check their protective clothing again, the transfer will be opened in a minute."

The two looked at each other, and they both understood.

The release of anesthetic gas does not stop during transfer.

After the two breathed again, Lin An first stood up.

He walked over to the pit and pointed to the edge of it.

Herman also got up, shook his head at Lin An, and motioned for Lin An to follow him.

Then the two of them stood against the wall near the secret door, and Herman pulled out his knife.

At this time, the two traffic lights on the wall, which were supposed to indicate the platform, suddenly changed color.

And this time, accompanied by a cacophony of machinery.

When the red light turned green, the secret door in the wall suddenly opened.

Herman held his breath and approached the secret door, Lin An following closely beside him.

Two staff members dressed in biochemical suits walked into the cell.

It's just that the two of them came in and were stunned for a moment in the empty cell.

Just as they were about to turn their heads to look behind them, Herman had already lunged forward.

He slashed at the neck of the staff member who was close to him.

Lin An ran to another staff member, and Herman threw the knife at him in an instant.

Lin An caught the knife and stabbed the staff member in the chest.

In less than twenty seconds, two staff members fell to the ground in an instant.

However, the first reaction of the two after doing this was not to run out of the secret door.

Instead, it was immediately flushed down the sewer pipe to ventilate.

After the two of them finished changing their breath, they were about to use the secret door to escape.

Lin An grabbed Herman and pointed to the two staff members lying on the ground.

Herman was in a state of mind, and the two began to take off the staff's biochemical suits.

Luckily, inside the biochemical suits, they also wore gas masks.

The two hurriedly put gas masks on their heads.

Then he put on the staff's biochemical suit and walked out of the secret door.

Outside the door, a corridor connected to an elevator was dimly lit.

There are also two stretchers with wheels and a tool cart on the corridor.

There are body bags, disinfectants, and other supplies used to clean the cells.

There are also brand new linen and bedding.

Lin An casually picked up a tool wrench from the tool cart, and Herman gave him a thumbs up.

The two walked to the elevator.

Lin An looked at the knife cut on the neck of Herman's biochemical suit, and there was a faint trace of blood.

I looked at the opening on my chest again, and it was the same.

So the two of them temporarily covered the mutilation on the biochemical suit with their hands, and then pressed the elevator button.

At this point, they can only pray that there is no one else in the elevator.

At this time, the two noticed a change in the elevator numbers, -100, -101, -102.

Lin An saw these numbers before he understood, it turned out that the prison floors of the two were built underground.

The elevator stopped at the number -177, and the doors slowly opened.

The two of them were breathless.

Sure enough, there were two other staff members standing inside.

Lin An and Herman's tacit understanding was shown again, and the two just walked into the elevator quickly.

Then he immediately turned around and turned his back to the two staff members.

They also put the knives and daggers that were hidden behind them in front of them the moment they turned.

They don't know if the two men noticed their anomaly.

and the two corpses lying on the ground looking out of the elevator door and through the secret door.

The two of them kept an eye out for the anomaly behind them, but the two behind them didn't seem to move.

Suddenly, the person behind him spoke, "How many floors are you going to?" ”

Lin An immediately swept his gaze quickly over the long elevator button, his math was very poor.

Judging by the level they were on, the prison was supposed to be partly above ground and partly underground.

First of all, Lin An was not sure if there was an exit on each floor on the floor.

But Lin An is sure.

The floors above the number of floors of the cell will definitely be different from the elevator entrance they just saw.

Lin An saw that the highest layer was 38 layers at this time, so he pressed 37 layers.

"What are you doing on the 37th floor?" The person behind him suddenly asked.

At first, the two didn't dare to speak, but finally Herman said, "We forgot something." ”

"Hey! You're not Bashir! The man behind said, grabbing Herman by the shoulder.
