Chapter 90： Hoarding! Fear of firepower! (2/2)
In everyday movies, you can often see the explosive packs **** like a quilt.
This kind of explosive package is called a group charge. It uses bulk powdered explosives, spread among cloth and paper, wrapped up like a package, and then **** and down with rope.
Cut the moldy sheets used to hold things into pieces, and tear off the notebook paper brought out from the ruins.
Put the picric acid into the bag according to the proportion, wrap it with cloth, and finally wrap it with scotch tape to complete the simple picric acid explosive bag.
In the middle of the dynamite bag, Somo put in the black powder used to ignite the dynamite bag and fixed it.
At this point, everything is ready, only the last fuze to be ignited!
There are many types of fuzes, including trigger fuze, proximity fuze, weekly bomb fuze, time fuze, command fuze and multi-select fuze.
”Hey, the manufacturing process of the fuze is very complicated, and there are a lot of things needed, but...”
”I have a system!”
As soon as he thought of the system, Somo immediately felt refreshed and flew up. He laughed twice before concentrating his mind directly and summoning the system interface.
After clicking on the creation interface, Suma whispered:
”System to create the simplest trigger fuze, the cheapest one”
[Detected creation needs, retrieved landmines to trigger fuzes, demand 90 creation points]
”Landmine triggers the fuse? What?” Seeing the system's prompt, Somo curiously clicked on the card that triggered the landmine to trigger the fuse.
A line of description neatly written on the card:
The oldest landmine trigger fuze, the ignition power comes from the gravity of the falling rock. The trigger mechanism consists of an iron needle, a rotating steel (iron) wheel, a falling rock, a flint and a pulling rope.
When setting up, tie the two ends of the rope to the falling stone and the steel (iron) wheel respectively, and set the rope as a trip rope, and then place the falling stone on a high place.
When a person or livestock stumbles on the rope, the falling rock falls from a height. When it falls, it drives the steel wheel to rotate, rubs against the flint and ignites, ignites the gunpowder fuse, and ignites the charge of the mine through the fuse.
”In 1560? Is this a trigger fuse from the 15th century?” Smash it. After thinking about it, Somo gave up this ancient trigger device.
Although this device is cheap, its practicality is very low, especially in the column of trigger success rate, which is only 60%, which is extremely unstable.
”Retrieved the cheapest trigger fuze after the 19th century”
[Detected creation demand, retrieved mechanical pressure fuze, demanded 99 creation points]
”Okay! Just want this thing!”
Hearing that the price of the pressure fuze was not as high as a bowl of mutton steamed bun and two steamed buns, Somo's eyes flashed, and he did not hesitate to exchange 5 pressure fuzes.
495 survival points were deducted, and a green light scattered out, and began to paint on the workbench in front of you!
The green frame structure like 3D printing gradually began to take shape, and after three to five seconds, five disc-shaped devices were slowly formed.
From this perspective, Somo can clearly see the generation process of each component inside, and can also clearly see the principle and method of triggering~~ Unfortunately, I didn't wait for Somo to look carefully and remember. , With a bang, five discs fell on the workbench with a muffled sound.
After opening the card of the mechanical trigger fuze, after looking at it for a while, Somo remembered the complete way of using it.
This kind of trigger fuze, as long as the insurance is opened and placed on the explosive bag, if anyone stepped on it, the detonator below will be triggered, thereby detonating the picric acid explosive bag.
At that time, all the enemies chasing will clearly taste the power of ”scientific” magic!
Not enough explosives for a pound? I'll give you ten catties!
What kind of fireball technique, what kind of population advantage, will become a joke under the ”firepower phobia” of Huaxia people.
”System, how many survival points are needed for a 10-minute fuze!”
[Detected creation needs, retrieved time fuze (length 10 minutes), demand creation point 20 points]
”so cheap?”
Flipping the card introduction, Sumo was surprised to find that the time fuze only needs 2 points per minute, and every minute it extends, the demand will increase by 2 points.
After thinking about it, with a big wave, Somo directly exchanged 3 sticks for 10 minutes, 5 sticks for 5 minutes, and 15 sticks for 3 minutes.
A total of 200 survival points are spent.
What appeared this time is very simple, like a string, only need to be ignited, it will slowly start to burn, when the time comes, after igniting the black powder in the middle of the explosive bag...
boom!
Turning his head, looking at the darkening sky outside, Sumo used his mouth to make a boom!
”It won't take long...”
”Early tomorrow morning, let the kobolds know what art is!”
