Chapter 90
"Excellent quality! I actually rely on my own ability to create excellent quality!"
Picking up the iron axe, Su Mo carefully studied every percussion mark on the axe. From top to bottom, Su Mo saw it three times, and still felt happy.
"It's a qualitative leap from never getting started to getting started!"
Taking out a unit of wood, Su Mo gently cut it down, with a clang, and the wood broke in response.
Like cutting through the water, there was no big resistance in the whole process.
There are such "productivity" tools, not to mention the axe produced by the assembly line on the earth. Even if you use the electric saw, it may not be so efficient.
"Sure enough, other species have the advantage of body or fantasy side, but human..."
"The advantage of human beings is always the brain full of wisdom and imagination, as well as the hands that make sophisticated tools!"
"What fireball, technology! Is the strongest weapon!"
Put the iron axe aside and return to the living room.
Sure enough, new pictures have appeared on the TV, and on the basis of just now, there is still a more standard way to create.
After a quick look, Su Mo gave up the idea of continuing to study and try.
People should not be greedy and rash.
The teaching just now is not comprehensive, and it is too easy to learn new skills rashly. The foundation is unstable, and it is difficult to make progress in the end.
Return the picture to the beginning, sit on the stone bench, and after a while, Su Mo started recording.
This time, what needs to be made is not tools, but Picric acid!
"Although the picric acid produced in a hurry last time was upgraded to the excellent level due to the workbench, there was no addition of any properties. It should be that there was something wrong with my steps and preparation methods."
"But even so, it's powerful enough. Now what I need more is stability. I must find a good way to detonate safely!"
Looking at the picric acid manufacturing flow chart traded from the tundra refuge, Su Mo frowned and thought about the method of preparing the bomb.
The reason why picric acid has been eliminated is that it's not easy to explode. It explodes at a little.
However, picric acid will explode immediately after it touches an object and has no armor piercing ability at all.
Moreover, if you put too much of this thing, you will be within the explosion range. If you put too little of it, it will not have enough killing effect.
Of course, the optimal solution must be to make mines, then seduce the enemy and use mines to kill the enemy.
"Unfortunately, if you want to make mines, my hand rubbing level is not enough, and the raw materials are not very good!"
"It seems that we can only use the most primitive explosives to deal with the current situation!"
After thinking through the idea, the next work is only one - mass preparation of picric acid raw materials!
Just like rubbing weapons and ammunition before fighting monsters in the farming game, sitting in front of the workbench, Su Mo patiently completed each step.
From the preparation of sulfuric acid and nitric acid to phenol disulfonic acid!
Every step, watching the teaching pictures on the TV repeatedly, Su Mo tried his best to achieve the ultimate!
Finally, the prepared nitric acid is introduced into phenol disulfonic acid. After the nitrification reaction is completed, fresh picric acid is released!
This time, Su Mo looked again, and finally showed a satisfied look.
[picric acid explosive trinitrocresol (excellent)]
Description: the dynamite made by the entry-level craftsman "sumo" is insoluble in carbon tetrachloride, slightly soluble in carbon disulfide, soluble in hot water, ethanol, ether, and easily soluble in acetone, benzene and other organic solvents. Because the preparation method strictly follows the scientific concept, it has reached the excellent level.
Property: melting point 121.8 ℃, boiling point: >300 ℃ (explosion)
Special ability: stability: in the process of 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! It's not good. The whole village has a feast!
"It takes 300 degrees to explode. Although explosive crossbows have become a thing of the past, it is the most suitable for making explosive bags!"
Looking at a kilogram of picric acid explosives in front of him, Su Mo gently took a small basin and put all picric acid crystals in it.
In the next half day, sitting in front of the workbench, Su Mo repeatedly repeated this boring process.
Every time Su Mo wants to give up, he will feel excited to see more and more yellow crystals piled in the corner!
Five kilograms of toluene, plus all the saltpeter seized before, produced a total of 30 kilograms of picric acid.
Converted to 60 Jin of explosives!
Su Mo plans to make three 10 jin, five 3 Jin and 15 1-jin explosives for these quantities.
The former is used to destroy enemy buildings, while the latter is used as a weapon at a fixed point!
Explosive bags tied like quilts can often be seen in daily movies.
This kind of explosive package is called group charge. It uses loose powder explosives, spread among cloth and paper, wrapped like a package, and then tied horizontally and vertically with ropes.
Cut the moldy sheets used to hold things into pieces, and tear down the notebook paper brought out from the ruins.
After putting picric acid into it in proportion, wrap it with cloth, and finally wrap it with scotch tape, the simple picric acid explosive bag is made.
In the middle of the explosive package, sumo put black powder used to ignite the explosive package and fixed it.
At this point, everything is ready except the fuse that was last used to ignite!
There are many kinds of fuzes, including trigger fuze, proximity fuze, perimeter fuze, time fuze, command fuze and multi-choice fuze.
"Hey, the manufacturing process of fuze is very complicated, and there are still many things needed, but..."
"I have a system!"
At the thought of the system, sumorton felt cool and flew up, laughing twice, directly concentrating his mind and calling out the system interface.
Click to the creation interface, and Sumo whispered:
"System, make the simplest trigger fuse, the cheapest one"
[creation demand is detected, mine trigger fuse is retrieved, and 90 creation points are required]
"Landmine trigger fuse? What" seeing the prompt of the system, Su Mo curiously opened the card of landmine trigger fuse.
A line of description is neatly written on the card:
The oldest mine trigger fuse is powered by the gravity of falling stones. The trigger mechanism is composed of iron needles, rotating steel (iron) wheels, falling stones, flints and pulling ropes.
When setting, the two ends of the rope are respectively tied to the falling stone and the steel (iron) wheel, and the rope is set as a trip rope, and then the falling stone is placed high.
When people or livestock trip the rope, the falling stone will fall from a high place. When it falls, it will drive the steel wheel to rotate, rub with the flint to ignite, ignite the gunpowder fuse, and ignite the charge of the mine through the fuse.
"1560? Is this the trigger fuse of the 15th century?" Smash it, smash its mouth. After thinking carefully, Su Mo still gave up this ancient trigger device.
Although this device is cheap, its practicability is very low, especially in the column of trigger success rate, which is only 60%, and it is extremely unstable.
"Search time: after the 19th century, the cheapest trigger fuse"
[detection of creation demand, retrieval of mechanical compression fuze, demand creation point 99 points]
"Good! That's what I want!"
Hearing that the price of hair pressing fuses was not as high as a bowl of mutton steamed bun and two meat buns, Su Mo's eyes flashed, and he did not hesitate to exchange five hair pressing fuses.
495 survival points deducted, a green light scattered out, and began to paint on the workbench in front of me!
The green frame structure like 3D printing gradually began to take shape, and after three or five seconds, five disc-shaped devices slowly formed.
From this perspective, sumo can clearly see the generation process of each component inside, as well as the principle and method of triggering.
Unfortunately, before Su Mo looked carefully and remembered it, five discs fell on the workbench with a thud, making a dull noise.
After opening the card of the mechanical trigger fuse and reading it for a while, sumo remembered the complete way of use.
This triggered fuse, as long as the fuse is opened and placed on the explosive package, will trigger the detonator below whenever someone steps on it, thus detonating the picric acid explosive package.
At that time, all the pursuing enemies will clearly taste the power of "science" magic!
One kilo of explosives is not enough? I'll give you ten jin!
Under the "fire phobia" of Chinese people, whatever fireball technique and crowd advantage will become a joke.
"System, how many survival points does the fuse need in 10 minutes!"
[the creation demand is detected, the time fuse is retrieved (10 minutes in length), and the creation point of demand is 20 points]
"So cheap“
Turning the card introduction, sumo was stunned to find that the time fuse only needs 2 points a minute, and each minute of extension will increase the demand by 2 points.
After thinking for a while, with a big wave of his hand, Su Mo directly exchanged three 10 minute, five 5 minute, and 15 3 minute.
It costs 200 survival points in total.
What appears this time is very simple, like a string. Just ignite it, and it will slowly start to burn. When time comes, ignite the black powder in the middle of the explosive package
Boom!
Turning his head, looking at the dark outside, Su Mo made a boom mouth with his mouth!
"It won't be long..."
"Tomorrow morning, let the dog head know what art is!"
Picking up the iron axe, Su Mo carefully studied every percussion mark on the axe. From top to bottom, Su Mo saw it three times, and still felt happy.
"It's a qualitative leap from never getting started to getting started!"
