Reinforced concrete is the best medium for transmitting sound. They bring back the sound of rapid footsteps. The thugs have completed the blockade and are rushing in through the front door!
The gunfire rang out, and the orange light suddenly lit up in the darkness, hitting the door and splashing out brilliant orange sparks.
The other side is already trying to defeat the enemy and is no longer prepared to hide it as a survivor base.
In the darkness, all kinds of modern machinery and equipment had been silent for a long time and were covered with dust. The only sounds that echoed in the air were the roar of engines and the sound of gunshots on the streets in front and behind.
The world fell into a strange, black silence.
Bi Fang suddenly asked Matthew: "Did you see any other roads when you came here? Ones like ventilation pipes that don't take ordinary people's roads?"
Matthew shook his head nervously: "No, I didn't find the way. I came in through the side door that was blown open. Was that done by you? What a spectacular scene. What did you use to blow it up? Is there anything else? We
Yes or no……"
Bi Fang did not answer.
The acetylene bottle is too heavy, and it is not easy to ignite and detonate. It is similar to fuse explosives and is extremely inconvenient. It is not easy to use this to break through the encirclement.
"Walk!"
Bifang suddenly grabbed Matthew's wrist and ran towards the darkness. Matthew was staggered, but he quickly followed and hid behind a load-bearing wall with Bifang.
The next moment, an explosion sounded, the door lock was broken, and people poured in from the entrance. The flashlight beam swept across the bottom of the first floor, revealing the place where the two people were hiding just now.
Under the light beam, Bifang could even see the type of firearms each of them carried, most of which were short-barreled shotguns.
"When a shotgun is fired, it is a barrage. If it is equipped with a single-end bullet, it is very suitable for breaking down the door. But if they want to arrest people, they will definitely not use single-end bullets, but ordinary shotguns. Such bullets are not fatal if they hit the body.
, but for the person who was hit, life would be worse than death.”
Bi Fang turned his head and glanced down, confirmed the grouping and whereabouts of several people, and then tilted his head.
"Dozens of lead beads will embed themselves into the flesh and blood in an instant, forming a honeycomb-shaped wound, and you can't even bleed out because the bleeding opening is blocked by the lead beads, but the wound may be
It will never get better in this life."
The thugs don't kill, the living have value, the dead can only donate their organs. If the time is not controlled well, they won't even be able to contribute their organs, and their value will be greatly reduced.
Hearing such a tragic situation, Matthew shuddered, as if a cold snake crawled through his heart.
The audience was even more anxious, but they didn't know what to do. There was nothing they could do to help through the screen, and they didn't dare to, so they had no choice but to cheer Bifang up on the barrage.
But this effect is not as effective as giving Bi Fang an empty gun...
On the first floor, the thugs fired shots, threatening the survivors to come out. One wooden door after another was violently blasted open, paper and sawdust flew into the air, and dust filled the air.
The silent factory became noisy and noisy. In such a tense atmosphere, Bi Fang suddenly closed his eyes.
A huge three-dimensional map grew wildly in his mind like tree branches. Huge factories were broken down into squares, old roads were blocked, and new road combinations were generated.
Time passed by, and Matthew looked nervously at the thugs, his heart beating violently. Under the light, he saw the stairs in the corner, and the thugs were approaching!
The corridor did not belong to the steel factory that Bi Fang had sneaked into before. The steel factory did not distinguish floors. The ceiling was suspended very high, and only some of the beams were fenced to form a passage like a corridor.
When Bi Fang reached the top floor and climbed out from the balcony, he was already in another factory building.
Just when Matthew turned around and tried to remind Bifang, he suddenly found that Bifang had closed his eyes.
What?
"They're coming up."
Matthew urged nervously. Just when he thought Bifang had fallen asleep, a pair of bright eyes suddenly opened in the darkness.
Bi Fang dragged Matthew and walked inside.
"Just now when I was sliding down the pipe, I vaguely saw a sewer outlet on the third floor. It is very large in diameter, about twenty inches, which is about half a meter. It is very thick. It may be a sewage outlet, or it may be an employee bathhouse.
It's not difficult for the two of us to get through it, but we have to get up first!"
"How to get up there?"
"stairs."
You can go down the pipe, but you can't go up. If you climb the pipe now, you will only be used as a target if you are discovered. Any method that cannot rise quickly is not practical at this time.
Matthew knew this, but he just realized that someone was already exploring towards the entrance of the corridor: "But there is someone over there!"
"Then kill them... Do you have a lighter?"
"have!"
Bi Fang stretched out his hand towards Matthew, and a windproof lighter was immediately stuffed into his palm.
Matthew was not here to survive. He had all the basic equipment with him. Although he lost most of it when he was chased, he still had some small tools.
Bi Fang wrapped his left hand with a strip of cloth, held the barrel of the gun, then took out the 7.62mm rifle bullet from his trouser pocket, picked up a snakeskin bag from the ground, cut off a small piece with a dagger to wrap the bullet,
Stuffed into a steel pipe.
"As the largest consumable on the battlefield, bullets usually consist of four parts: warhead, propellant, cartridge case and primer. The structure of this thing has basically not changed much since it was designed in the 19th century."
"When shooting, first pull the trigger, the firing pin will hit the bullet primer and then ignite the propellant in the cartridge case. When the gunpowder burns and the internal pressure of the cartridge case rises to 250 to 500kg/cm2, the warhead will be pushed out of the cartridge case and squeezed into the rifling
, and is quickly ejected under the action of high-pressure gas, causing damage to the target through powerful kinetic energy."
Bi Fang led Matthew towards the corridor entrance very calmly, his tone did not fluctuate much, as if he was not the one in danger.
After turning the corner, there was a crisp metal sound. Bifang pushed open the lighter cover, rubbed the flint, lit the lighter, and burned the bottom of the bullet in the steel tube. Matthew's eyelids twitched as he watched, and he calmly said
He took a few steps away, but the next second, a burst of gunfire from downstairs brought him closer.
"The primer will ignite the propellant and eject the warhead in a high-temperature environment or by a violent impact. Some warheads are very heavy, and the gunpowder will first explode from the thinner shell after firing. Therefore, it is very likely that the shell will explode, but the bullet will not
Couldn't launch."
"So we cannot use pistol bullets with short bullets and heavy bullets. We can only use rifle bullets with light bullets and long bullets."
"Many people will definitely think that after roasting the bullet with fire, the fired bullet will fly around in the air and accidentally hit the person next to you. But this is not the case. Although the bullet leaving the gun may explode, if
It's not as dangerous as you think if you keep a safe distance."
"Wait...you're going to fire a bullet!?"
Matthew exclaimed, as if he had just realized at this moment that the whole factory was full of gunshots, so there was no need to lower his voice deliberately.
"Just use this..."
A deafening sound of gunfire blocked what Matthew wanted to say. He stared blankly at the bullet holes in the wall, speechless and choked.
Bi Fang shook his numb left hand and glanced at the dull Matthew.
"has a problem?"
The male northern grunt boat moth can drink 600 times more water than its body weight and urinate more than 4,000 times in three and a half hours. This is to extract the sodium element in the water and donate it to the female moth through sperm as a necessary nutrition for the birth of larvae.
