My Post-Apocalyptic Shelter Levels Up Infinitely! - Chapter 94

[Chapter 93 Big Hoarding!]

“Excellent quality! I actually rely on my own ability to create excellent quality!”

Picking up the iron axe, Soma carefully scrutinized every strike mark on the axe, from top to bottom, Soma watched it three times and still felt joy.

“It’s really a qualitative leap from not getting started to getting started!”

Taking out a unit of wood, Soma gently chopped it down, and with a bang, the wood broke.

It was like cutting through the water without encountering any major resistance throughout the process.

With such a “productivity” tool, let alone an axe produced by an assembly line on the earth, even a chainsaw may not be so efficient.

“Sure enough, other species have physical or fantasy advantages, but human beings.”

“Human’s advantage is always a brain full of wisdom and imagination, and hands with well-made tools!”

“What fireball, technology! The strongest weapon!”

Putting the iron axe aside, he returned 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, Soma gave up the idea of continuing to learn and try.

People can’t be greedy for success.

The teaching just now has not been fully integrated, and rashly learning new techniques is too easy to pull the seedlings and encourage them, the foundation is unstable, and it is difficult to progress in the end.

Returning the screen to the beginning, sitting on the stone bench and closing the scene for a while, Soma started the recording.

This time, it is not the tools that need to be made, but the picric acid!

“Although the picric acid that was made in a hurry last time has been upgraded to an excellent level due to the workbench, it does not have any attribute bonuses. It should be a problem with my steps and preparation methods.”

“But even so, the power is strong enough. Now what I need more is stability. I must find a good way to detonate it safely!”

Looking at the picric acid production flow chart traded from the Tundra Refuge, Soma Frowning, he pondered 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 point.

However, after a violent collision with an object, the picric acid will explode immediately, and there is no armor-piercing ability at all.

And if you put too much of this thing, you will be within the explosion range, and if you put too little, it will not be enough to kill.

Of course, the optimal solution must be to make mines, then lure the enemy up and use mines to kill them.

“Unfortunately, if I want to make mines, my hand rubbing skills are not enough, and the raw materials are not enough!”

“It seems that the most primitive explosive packs can only be used to deal with the current situation!

” There’s only one job left to do – make picric acid ingredients in bulk!

Sitting in front of the workbench, Soma patiently completed every step, just like rubbing weapons and ammunition before fighting monsters in a farming game.

From the preparation of sulfuric acid and nitric acid, to phenol disulfonic acid!

Every step, repeatedly watching the teaching screen on the TV, Soma tried his best to achieve the ultimate!

With the final addition of the prepared nitric acid to the phenol disulfonic acid, after the nitration reaction is completed, fresh picric acid is released!

This time, Soma looked around again and finally showed a satisfied look.

[Piric Acid Explosive-Trinitrocresol (Excellent)]

Description: An explosive made by the entry-level craftsman “Suma”, insoluble in carbon tetrachloride, slightly soluble in carbon disulfide, soluble in hot water and ethanol , ether, easily soluble in acetone, benzene and other organic solvents, because the preparation method strictly follows the scientific concept, so it has reached the excellent level.

Properties: Melting point: 121.8℃, Boiling point: >300℃ (explosive)

Special ability: Stability: In the process of completing the preparation, it is scientific and reasonable, and the stability of the explosive is increased. (It will never explode below 300 degrees)

Evaluation: Good order, everyone is happy! If the order is not good, the whole village will eat!

“It takes 300 degrees to explode, although explosive crossbow bolts are a thing of the past, but it is the most suitable for making explosive packs!”

Looking at the full kilogram of picric acid explosives in front of him, Soma gently took a small pot, and put all the picric acid crystals in it.

For the next half-day, sitting in front of the workbench, Soma tirelessly repeated this boring process.

Every time Soma wants to give up and sees more and more yellow crystals piled up in the corners, it’s heartening!

Five kilograms of toluene, plus all the saltpeter that was snatched earlier, made a total of 30 kilograms of picric acid.

Converted to a full 60 pounds of explosives!

For these weights, Somo plans to make 3 10-jin, 5 3-jin, and 15 1-jin explosive packs.

The former is used to destroy enemy buildings, and the latter is used as a weapon at a fixed point!

Dynamite bags bundled like quilts can often be seen in everyday movies.

This explosive package is called a group charge, which is made of bulk powdered explosives, spread among cloth and paper, wrapped like a package, and then tied with ropes horizontally and vertically.

Cut the moldy sheets that were used to hold things in pieces, and tear off the notebook paper that was brought out of the ruins.

After the picric acid is put into the bag according to the proportion, wrapped with cloth, and finally wrapped with transparent tape, the simple picric acid explosive pack is completed.

In the middle of the explosive pack, Soma put the black powder used to ignite the explosive pack and fixed it.

At this point, everything is ready, just the last fuse to ignite!

There are many types of fuzes, including trigger fuzes, proximity fuzes, weekly fuzes, time fuzes, command fuzes and multi-select fuzes.

“Hey, the manufacturing process of the fuze is very complicated, and there are still a lot of things needed, but”

“I have a system!”

Thinking of the system, Somo suddenly felt refreshed, laughed twice, and concentrated his thoughts directly. The system interface was summoned.

Clicking on the creation interface, Soma said softly:

“System, make the simplest trigger fuze, the cheapest one”

[Detected the creation demand, retrieved the mine trigger fuze, and the survival point is 90 points]

“Mine Trigger the fuze? What?” Seeing the system prompt, Soma curiously clicked on the mine-triggering fuze card.

A line of description is neatly written on the card:

the oldest mine triggers the fuze, the ignition power comes from the gravity of the falling stone, and the trigger mechanism is composed of an iron needle, a rotating steel (iron) wheel, a falling stone, a flint and a pulling rope.

When setting, fasten the two ends of the rope to the falling stone and the steel (iron) wheel respectively, and set the rope as a trip wire, and then place the falling stone at a high place.

When people or livestock stumble on the rope, the falling stone will fall from a height. When it falls, it will drive the steel wheel to rotate, rub against the flint and ignite, ignite the gunpowder fuse, and ignite the mine’s charge through the fuse.

“1560? This is the trigger fuze of the sixteenth century?” After thinking about it carefully, Soma 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.

“The cheapest trigger fuze after the retrieval time of the 19th century”

[Detected the creation demand, retrieved the mechanical pressing fuze, and required 99 creation points]

“Okay! This is what I want!”

Hearing that the price of the fuze was not as high as a bowl of mutton steamed buns and two meat buns, Su Mo’s eyes flashed, and he exchanged 5 fuzes without hesitation.

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 or five seconds, five disc-shaped devices were slowly formed.

From this perspective, Soma can clearly see the generation process of each component inside, and can also clearly see the principle and method of triggering.

It’s a pity that, before Soma could look at it carefully and remember, with a bang, the five discs fell on the workbench, making a muffled sound.

After opening the card of the mechanical trigger fuze, and after reading it for a while, Soma remembered the complete usage method.

This kind of trigger fuze, as long as the insurance is pulled out and placed on the explosive pack, if someone steps on it, it will trigger the detonator below, thereby detonating the picric acid explosive pack.

At that time, all chasing enemies will clearly taste the power of “scientific” magic!

One pound of explosives isn’t enough? I’ll give you ten pounds!

Any fireball technique or the advantage of a sea of people 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!”

[The creation requirement is detected, and the time fuze (10 minutes in length) is retrieved, and 20 creation points are required]

“So cheap?”

Flip the card introduction, and Soma was stunned to discover , the time fuze only needs 2 points per minute, and every minute that is extended will increase the demand by 2 points.

After thinking about it, with a big wave of his hand, Soma directly exchanged 3 10-minute, 5 5-minute, and 15 3-minute coins.

A total of 200 Survival Points are spent.

The thing that appeared this time is very simple, like a string, it only needs to be ignited, and it will slowly start to burn. When the time comes, after igniting the black powder in the middle of the explosive pack.

boom!

Turning his head and looking at the dark sky outside, Soma used his mouth to make a boom mouth shape!

“It won’t take long.”

“Tomorrow morning, let the kobolds know what art is!”

Thanks to all the readers who voted for the monthly ticket, la la la, I am so happy to see the monthly ticket!
