Global wasteland: I am as good as a god with a machine

The ventilation ducts in the hospital are so narrow that people can only move in a crawling position.

Wu Mian's body was very stiff when crawling due to his ceramic spine, while Nan Ci in front was even more uncomfortable.

When marching before, Nan Ci could carry the unconscious Ning Guangyuan on his back, but after entering the ventilation duct, he could only choose to tie a rope to Ning Guangyuan's armpit and drag him forward.

It was pitch dark inside the ventilation duct. Nan Ci could crawl forward using the night vision function of the electronic eyes, while Wu Mian could only follow behind, identifying the direction through sounds and groping, and at the same time setting up easy-to-find booby traps to intimidate pursuers behind.

The soldiers dared not come forward.

Ten seconds later, Nan Ci had climbed to a fork. Looking to both sides, there were empty pipes on both sides.

The hospital's pipelines extend in all directions. If they choose the wrong direction, they can only go in circles on the same floor. At this time, they have been exposed. If they choose the wrong path, they will be in disaster.

Seeing Nan Ci stop, Wu Mian asked, "Why don't you leave?"

Nan Ci whispered: "There is a road on the left and right. I don't know where to go. We are taking Ning Guangyuan with us. Once we go the wrong way, it will be difficult to go back."

Wu Mian took out a kerosene lighter from his pocket and threw it towards Nan Ci: "We are in the basement, and the vent is for outdoor ventilation. Go up to the vent."

Nan Ci picked up the lighter that had fallen beside him, lit it, checked the direction with the faint sway of the flame, and then crawled to the left.

The two of them were lucky. The pipes here did not go straight up and down. In order to facilitate ventilation and avoid dust accumulation, they were all tilted. Although Nan Ci could not determine his position, he could feel that he was always moving upstairs.

About forty seconds later, the angle of the pipe changed from tilt to horizontal. Nan Ci saw a light coming from the end of the pipe, and was about to continue moving when Wu Mian's voice suddenly came from behind: "They must be ventilating all the

There are manpower deployed at the entrance, we can’t leave from that place!”

Nan Ci stretched out his hand and pressed the wall of the ventilation duct: "The air duct here is made of composite metal. If it explodes, it will make more noise. Moreover, the explosion in the confined space is also a danger to ourselves!"

Wu Mian spoke quickly: "Look for bends. This type of ventilation duct will have airtight cleaning holes near special-shaped pipe fittings that are prone to dust accumulation."

Hearing this, Nan Ci sped up his movements: "There is a fork in front of you on the right, follow me."

Wu Mian followed behind, and just as he helped Nan Ci push Ning Guangyuan into the pipe, he heard a noise coming from the front.

The cover of a vent was opened, and a pistol with a gunlight was inserted into the pipe. The gunman saw Wu Mian illuminated by the light, and before he could react, he heard a gunshot.

"boom!"

Wu Mian shot the opponent in the head with one shot, shook his head to suppress his ears that were buzzing from the echo, stepped on the wall and slid into the fork of the pipe.

"Bang bang bang!"

Another hand reached in and fired a few random shots into the pipe, and then there was a cry: "People are in the pipe on this floor, seal off several surrounding rooms!"

Seeing that they had been exposed, Nan Ci knew that it would be even more disadvantageous to continue hiding in the pipe. He kicked off the baffle in front, looked down sideways, made sure there was no one in sight, blocked the upper side of the baffle with his legs, and hung his upper body upside down.

, and at the same time pointed the muzzle at the previous visual blind spot.

Nan Ci confirmed that the room was safe, adjusted her body shape by lying on her back, grabbed the edge of the vent with her hands, and jumped out. Wu Mian also pushed Ning Guangyuan down with a tacit understanding, and then jumped out of the pipe.

The location they were in was the pharmacy room in the hospital, surrounded by shelves with all kinds of medicines.

The pharmacy has always been a place where no one is allowed to enter, so their room has no windows and only a security door in the front.

The security door was not soundproof. The two of them were inside the house and could already hear the shouting and the sound of other doors being kicked open, and the sound was still moving towards them.

Wu Mian knew that the two of them alone could not hold the room, so he stepped on the shelf and was about to leave: "Get back!"

"We can go up, but we can't bring him up!"

Nan Ci glanced at Ning Guangyuan who was lying on the ground, then at the three-meter-high ceiling, and whispered: "I have informed Zhu Tao that they are coming in to respond, so we can only hold on!"

Wu Mian gritted his teeth helplessly, and then started rummaging around on the shelves next to him.

Nan Ci saw Wu Mian's actions and pointed his gun at the door as a warning: "What are you looking for?"

"If you want to win more with less, explosives are the best weapon... Found it, nitroglycerin oil injection." Wu Mian picked up an infusion bottle: "The scientific name of nitroglycerin is glycerin trinitrate, which is a nitric acid

Ester explosives, which are about 1.4 times more powerful than tn.t, can also be used as relief drugs for angina pectoris."

"I know its ingredients." Nan Ci reminded: "The nitroglycerin solution is diluted."

"Its excipient is absolute ethanol. This solution itself will release carbon monoxide, which will cause an explosion in the event of a violent collision. If it is ignited artificially, the probability of explosion will be even higher!"

As Wu Mian spoke, he began to unscrew the bottles of nitroglycerine solution one by one, stuffing medical cotton into the mouth of the bottle: "Give me the lighter!"

…

In the corridor outside, a group of gang members searched one by one from both sides and soon gathered in front of the pharmacy door.

One of them rummaged through the keychain in his hand, took out the key with the pharmacy room label, inserted it into the keyhole, slowly opened the door lock, and at the same time turned his gaze to his companion.

The companion raised his pistol with both hands, aimed at the door, and nodded.

"Bang!"

The door was pushed open violently, and the two gunmen stood facing each other, pointing into the room on the left and right sides, locking the shooting range in the room to the greatest extent.

After confirming that their line of sight was safe, the two men turned their guns and entered the door, pointing back to back at both sides of the door.

People outside filed in, preparing to search.

"Crash!"

Suddenly, a medical cart covered in a white coat rushed toward the crowd from the gap in the shelves in front.

"Bang bang bang!"

A gunman quickly turned around and repeatedly pulled the trigger on the cart. The smell of alcohol suddenly spread in the air.

"Bang!"

Under the impact of the bullet, the medical cart deviated from its route and hit the shelf. The medical alcohol bottles on the cart were thrown out by the inertia, and the alcohol spilled all over the floor.

Before the person at the door could react what was going on, another infusion bottle flew over from behind.

"boom!"

The ignited nitroglycerin and oil solution hit the ground, and a fireball exploded in an instant.

The crowd that had just rushed in was instantly enveloped in flames. The few people at the front who were covered in alcohol wailed and began to retreat out of the door.

"Bang bang bang!"

Wu Mian took advantage of the chaos in the crowd, appeared behind a shelf in front, and began to pull the trigger continuously.
