My Post-Apocalyptic Shelter Levels Up Infinitely!

The ninetieth chapter of the main body hoarding! Fear of firepower! (First more)

"Excellent quality! I actually rely on my ability to create excellent quality!"

Picking up the iron axe, Somo looked at every mark on the axe. From top to bottom, Sumo looked at it three times, still feeling happy.

"From getting started to getting started, it really is a qualitative leap!"

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

As if cutting through the water, there was no big resistance during the whole process.

With such a "productivity" tool, let alone an axe produced on the earth's assembly line, even a chainsaw does not necessarily have such a fast efficiency.

"Sure enough, other species have physical or fantasy advantages, but humans..."

"The advantage of human beings is always a brain full of wisdom and imagination, and hands with well-made tools!"

"What fireball technique, technology! It is the strongest weapon!"

Put the iron axe 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 to create it.

After a quick look, Somo gave up the idea of ​​continuing to learn and try.

People cannot be greedy for meritorious advancement.

The teaching just now has not been thoroughly integrated, and rushing to learn new techniques is too easy to pull out and encourage, the foundation is unstable, and it is difficult to make progress in the end.

Returning to the beginning of the screen, after sitting on the stone bench and closing the curtain for a while, Somo started the recording.

This time, what needs to be made is not the tools, but... the bitter taste!

"The picric acid that was made in a hurry last time has been upgraded to an excellent level because of the workbench, but there is no addition of any attributes. It should be a problem with my steps and preparation methods."

"But even so, the power is strong enough, and now I need stability more, and I must find a good way to detonate safely!"

Looking at the picric acid manufacturing flow chart traded from the Tundra Refuge, Somo frowned and thought about how to make the bomb.

The reason why bitter sour is eliminated is because it is not easy to detonate, it will explode at a single point.

Whenever it touches an object and makes a violent impact, the picric acid will explode immediately, and there is no armor-piercing ability at all.

Moreover, if you put too much of this thing, you will be within the explosion range, and if you put too little, it will not have enough killing effect.

Of course, the best solution is definitely to make landmines, then seduce the enemy and use them to kill the enemy.

"It's a pity, if I want to make landmines, my hand rubbing is not enough, and the raw materials are not good enough!"

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

I figured out my ideas, and there is only one remaining task-preparing a large amount of picric acid raw materials!

Just like rubbing weapons and ammunition before fighting monsters in the farming game, sitting in front of the workbench, Suma 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, Somo tried his best to achieve the best!

As the phenol disulfonic acid is finally introduced into the prepared nitric acid, after the completion of the nitration reaction, fresh picric acid is out of the oven!

This time, Somo looked around again, finally showing a satisfied look.

【Piric Acid Explosive-Trinitrocresol (Excellent)】

Description: The explosive explosive made by the entry-level craftsman "Suma" is hardly soluble in carbon tetrachloride, slightly soluble in carbon disulfide, soluble in hot water, ethanol, ether, and easily soluble in organic solvents such as acetone and benzene. The preparation method strictly follows the scientific concept, so it has reached the 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 the explosive. (It will never explode below 300 degrees)

Evaluation: Good points, everyone is happy! The order is not good, the whole village eats a table!

"Although 300 degrees can explode makes explosive crossbows a thing of the past, it is actually the most suitable for making explosive packs!"

Seeing a full kilogram of picric acid explosive in front of him, Somo gently took a small basin and filled all the picric acid crystals into it.

Sitting in front of the workbench for the next half day, Somo tirelessly repeated this boring process repeatedly.

Every time Somo wants to give up, he feels excited to see more and more yellow crystals piled up in the corner!

Five kilograms of toluene, plus all the saltpetre robbed before, produced a total of 30 kilograms of picric acid.

The conversion is a full 60 kilograms of explosives!

With these weights, Somo intends to make 3 packs of 10 kg, 5 packs of 3 kg, and 15 packs of 1 kg.

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

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~www.readwn.com~ 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!"
