My Post-Apocalyptic Shelter Levels Up Infinitely! Chapter 90: Big hoard! Fire phobia!
Text Chapter 90 Big hoarding! Fire phobia! (First update)
"Excellent quality! I actually rely on my own ability to create excellent quality!"
Picking up the iron axe, Su Mo carefully looked at every strike mark on the axe. From top to bottom, Su Mo looked at it three times and still felt joyful.
"From no entry to entry, it really is a qualitative leap!"
Taking out a unit of wood, Su Mo chopped it down lightly, and with a clang, the wood snapped.
As if cutting through the water, the whole process did not encounter any major resistance.
With such a "productivity" tool, let alone an ax produced by an assembly line on the earth, even a chainsaw may not have such a fast efficiency.
"Sure enough, other species have physical or fantasy advantages, but humans..."
"The advantage of human beings is always the brain full of wisdom and imagination, and the hands with well-made tools!"
"What fireball, technology! It is the strongest weapon!"
Put the iron ax aside and return to the living room.
Sure enough, a new picture appeared on the TV, and on the basis of just now, there is still a more standard way of building.
After a quick look, Su Mo gave up the idea of continuing to study and try.
People should not be greedy for merit.
The teaching just now has not been fully integrated. If you rush to learn new techniques, it is too easy to backfire, the foundation is unstable, and it is difficult to make progress in the end.
Returning the screen to the beginning, after sitting on the stone bench to close the curtain and rest for a while, Su Mo started recording.
This time, what needs to be made is not a tool, but... picric acid!
"Although the picric acid produced in a hurry last time was upgraded to an excellent level because of the workbench, it didn't have any attribute bonus. It should be something wrong with my steps and preparation method"
"But even so, it's powerful enough. What I need more now is stability. I must find a good way to detonate it safely!"
Looking at the picric acid manufacturing process traded from the tundra shelter, Sumo frowned and thought about how to prepare the bomb.
The reason why picric acid was eliminated is because it is not easy to detonate, and it explodes at a single touch.
Whenever it touches an object and hits violently, the picric acid will explode immediately, without any armor-piercing strike ability at all.
Besides, if you put too much of this thing, you will be within the range of the explosion. If you put too little, it won't have enough lethal effect.
Of course, the optimal solution must be to make landmines, then lure the enemy to come up, and use the landmines to kill the enemy.
"Unfortunately, if I want to make landmines, my hand rubbing skills are not enough, and the raw materials are not good enough!"
"It seems that we can only use the most primitive explosive kit to deal with the current situation!"
After figuring out the idea, there is only one remaining task - to prepare a large amount of picric acid raw materials!
Similar to having to fiddle with weapons and ammunition before killing monsters in a farming game, Sumo sat in front of the workbench and patiently completed every step.
From the preparation of sulfuric acid and nitric acid, to phenol disulfonic acid!
Every step, watching the teaching screen on the TV repeatedly, Su Mo tried his best to do the best!
Finally, the prepared nitric acid is passed into the phenol disulfonic acid, and after the nitration reaction is completed, fresh picric acid comes out of the oven!
This time, Su Mo looked around again and finally showed a satisfied expression.
[Picric acid explosive - trinitrocresol (excellent)]
Description: A strong explosive made by the entry-level craftsman "Somo", insoluble in carbon tetrachloride, slightly soluble in carbon disulfide, soluble in hot water, ethanol, ether, easily soluble in acetone, benzene and other organic substances Solvents, due to the strict adherence to scientific principles of preparation, achieved an excellent level.
Properties: melting point 121.8c, boiling point: >300c (explosion)
Special ability: Stability: In the process of completing the preparation, it is scientific and reasonable, which increases the stability of explosives. (It will never explode below 300 degrees)
Evaluation: Good order, everyone is happy! If it's not good, the whole village will have a feast!
"It takes 300 degrees to explode, although exploding crossbow arrows are a thing of the past, but it is the most suitable for making explosive kits!"
Looking at a kilogram of picric acid explosives in front of him, Su Mo gently took a small basin and put all the picric acid crystals into it.
In the next half a day, sitting in front of the workbench, Su Mo tirelessly repeated this boring process.
Every time Sumo wanted to give up, he would feel inspired to see more and more yellow crystals piled up in the corner!
Five kilograms of toluene, plus all the saltpeter that was looted earlier, produced a total of 30 kilograms of picric acid.
Converted to a full 60 catties of explosives!
For these quantities, Sumo plans to make 3 10-jin packs, 5 3-jin packs, and 15 1-jin explosive packs.
The former is used to destroy enemy buildings, while the latter is used as a weapon for fixed-point use!
You can often see dynamite bundles tied like quilts in daily movies.
This kind of explosive package is called group charge. It uses bulk powdered explosives, spreads them among cloth and paper, wraps them like a package, and then binds them horizontally and vertically with ropes.
Cut the moldy bed sheets that were used to hold things into pieces, and tear off the notebook paper brought out from the ruins.
Put the picric acid into it according to the proportion, wrap it up, wrap it with cloth, and finally wrap it with scotch tape. The simple picric acid explosive bag is made.
In the middle of the dynamite bag, Su Mo put in the black powder used to ignite the dynamite bag and fixed it.
At this point, everything is ready, except for the last fuze to be ignited!
There are many types of fuzes, including trigger fuzes, proximity fuzes, weekly fuzes, time fuzes, command fuzes and multiple choice fuzes.
"Hey, the manufacturing process of the fuze is very complicated, and there are still many things needed, but..."
"I have a system!"
Thinking of the system, Su Mo suddenly felt refreshed, laughed twice, concentrated his thoughts, and summoned the system interface.
Click to the creation interface, Sumo said softly:
"System, make the simplest trigger fuze, the cheapest one"
[Creation needs detected, landmine trigger fuze retrieved, 90 points of creation required]
"The mine triggers the fuze? What?" Seeing the system prompt, Su Mo curiously clicked on the card of the mine triggering the fuze.
Write a line of description neatly on the card:
The oldest landmine trigger fuze, the firing power comes from the gravity of falling rocks, and the triggering mechanism is composed of iron needles, rotating steel (iron) wheels, falling rocks, flints and pulling ropes.
When setting, tie the two ends of the rope to the falling stone and the steel (iron) wheel respectively, set the rope as a trip wire, and then place the falling stone at a high place.
When a person or animal trips the rope, the falling stone will fall from a high place. When falling, it will drive the steel wheel to rotate, rub against the flint and ignite, ignite the gunpowder fuse, and ignite the charge of the mine through the fuse.
"1560? Is this a trigger fuze from the 15th century?" After thinking about it carefully, Sumo still 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.
"Search time after the 19th century, the cheapest trigger fuze"
[Creation needs detected, mechanical depressing fuze retrieved, 99 creation points required]
"Okay! This is what I want!"
Hearing that the price of depressing fuzes was not as high as a bowl of mutton steamed buns and two meat buns, Su Mo's eyes lit up, and he exchanged 5 depressing fuzes without hesitation.
495 survival points were deducted, a green light scattered out, and he began to paint and draw on the workbench in front of him!
The green frame structure like 3D printing gradually began to take shape, and after three to five seconds, five disc-shaped devices slowly formed.
Under this perspective, Sumo can clearly see the generation process of each component inside, and can also clearly see the principle and method of triggering~IndoMTL.com~It's a pity that I didn't wait for Sumo to look carefully and remember Suddenly, with a bang, five discs fell on the workbench, making a muffled sound.
Opening the card of the mechanical trigger fuze, after looking at it for a while, Su Mo memorized the complete usage method.
This kind of trigger-type fuze, as long as the safety is pulled and placed on the explosive package, whenever someone steps on it, the detonator below will be triggered, thereby detonating the picric acid explosive package.
At that time, all chasing enemies will clearly taste the power of "scientific" magic!
A catty of explosives is not enough? I'll give you ten catties!
What kind of fireball technique, what kind of crowd advantage, will become a joke under the "firepower phobia" of the Chinese people.
"System, how many survival points are needed for a 10-minute time fuze!"
[Creation needs detected, time fuze retrieved (10 minutes in length), 20 creation points required]
"So cheap?"
Flipping through the card introduction, Su Mo was surprised to find that the time fuze only needed 2 points per minute, and every minute it was extended would increase the demand by 2 points.
After thinking about it, with a wave of his hand, Sumo directly exchanged 3 10-minute sticks, 5 5-minute sticks, and 15 3-minute sticks.
Spent a total of 200 survival points.
The thing that appeared this time is very simple, like a string, it only needs to be ignited, and it will start to burn slowly. When the time comes, after igniting the black powder in the middle of the explosive package...
Boom!
Turning his head, looking at the darkening sky outside, Su Mo made a mouth shape of boom with his mouth!
"It won't be long..."
"Tomorrow morning, let the kobolds know what art is!"
