A passage appeared behind the code door, dimly lit and without a single person. Jack walked forward for a while when he noticed a steel door in front of him.

He took out two hooked wires that had been flattened at the front and stabbed them into the keyhole of the pachinko lock.

In less than thirty seconds, a click was heard and the lock was opened. Jack quietly pushed open the door and walked in, the room empty.

As soon as Jack entered the house, he closed the door and pressed the button on the doorknob to lock the lock. The room was forty square meters in size, with no windows, a desk and filing cabinet, and a frosted glass door on the right side, which could not be seen clearly, like a toilet.

Jack pulled out the cigarette holder from his pocket that was used to shoot the fast-acting poison needle, pinched both ends and pulled it, and opened the safe.

He took a deep breath, then put the cigarette holder to his mouth, pulled open the frosted glass door, and squatted at the same time.

Sure enough, it was a toilet, and there was a bidet toilet in it, and there was a resin door between the toilet and the frosted glass door, and there was no one to hide it. Jack smiled wryly, took the cigarette holder, and then shortened the cigarette holder to close the safety and put it back in his pocket.

Walk out of the bathroom, go to the desk, open the drawer, and start checking the contents, but there is nothing inside.

Jack muttered and walked over to the filing cabinet, which was locked.

Jack used wire to unlock the cabinet. When the lock opened with a crunch, there was a faint hissing sound from the ceiling.

It's like a gas spewing out. Jack banged on the cabinet door as he looked up for the noise coming from the ceiling.

The sound came from the fluorescent lights embedded in the ceiling and gradually intensified.

Jack turned his gaze to the cabinet, which contained many archival documents, and he was about to check them when suddenly, Jack smelled an ominous smell.

Quickly holding his breath, Jack knew that the ominous smell was very similar to the smell of hydrogen cyanide gas from bitter almonds. After inhaling hydrogen cyanide poison gas, if it is mild, the main manifestations of mild poisoning are chest tightness, palpitations, increased heart rate, headache, nausea, vomiting, and blurred vision; Severe poisoning will lead to a deep coma, shallow and rapid breathing, paroxysmal convulsions, and even tonic spasms, and finally death.

A chill suddenly appeared on Jack's spine, and he continued to hold his breath, rushed to the door and grabbed the handle and twisted it, but the handle didn't move. If it is an ordinary lock, as long as you turn the handle, the button will automatically jump out, and the door will open automatically.

However, this time even the handle itself could not be turned. Jack held his breath and used all his strength to hold the handle and twist it vigorously.

The muscles of anger caused the seams on the shoulders of the clothes to burst, and the bruises on the face and neck swelled to a red brick color, like the face of a demon.

There was only a click, and the cast iron handle shattered into many small pieces and remained in Jack's hand. Jack sat down on the floor, and the room shook with a thud. He quickly stood up, retreated to his desk, and slammed his left shoulder against the door.

The violent impact sent a scream from the flesh of the left shoulder.

Jack was bounced off and fell to the ground, the back of his head hitting the table and nearly inhaling poison gas. My lungs were very uncomfortable from the long breath holding and strenuous exercise, and my head began to feel a little dizzy.

Due to the poisonous gas, Jack was not only suffocated. Slight paralysis of the brain. My eyes hurt too. Even more painful is the need to overcome unbearable horror.

Jack ran into the bathroom. At this time, the air that was holding back had been exhaled little by little, and the lungs were empty.

I opened the door of the toilet room with a long slit, got inside, and quickly closed the door. Stand on the toilet and stand on tiptoe. Suck up the air from near the ceiling.

The hydrogen cyanide gas hadn't yet arrived, and the deep breathing relieved the aching lungs.

Jack came out of the toilet and took out the dagger. First, hold your breath. With a dagger. The carpet near the lower end of the steel door is cut first. On the exposed cement floor, use a dagger. The head was chiseled.

The dagger used by Jack. The first is a dagger made of special steel developed by the queen for agents. First, very strong and sharp.

The concrete floor was constantly being lifted like hard ground, and soon a small hole appeared under the door.

When the hole was dug, Jack's lungs began to feel uncomfortable again. He put away the dagger. First, take out the hand lei and pull out the pull tab of the hand lei.

At this point, just throw your hand at a hard object and it will explode. Even if the hand is not impacted, it will explode after ten seconds.

Jack shoved his hand into the hole under the door. Quickly run back to the toilet in the toilet, close the resin door between the toilets, and slowly exhale air.

In fact, only a few seconds passed, but it felt like hours. Jack could hold his breath for four and a half minutes at a depth of ten meters, but his face and body were covered in sweat. It is important to know that most people cannot hold their breath for more than a minute.

There was a loud bang, almost knocking out the ear drum. The shock wave and air wave shattered the glass on the toilet door. The outside of the resin door in the toilet bowl is covered with countless pieces of broken glass.

Jack pistol in hand, opened the resin door, and ran through the swirling room of gunsmoke and hot air. The steel door was blown out of the way, twisted out of shape.

Jack sprinted back, through the code door, to the underground parking lot, and took a big breath of air. Although the air is full of musty smells and car waste smells, it is incomparably sweet for Jack at this moment.
