Chapter 93: Big Hoarding! Phobia of Firepower! (First Update)

"Excellent quality! I actually created excellent quality with my own ability!"

Pick up the iron axe and carefully examine every mark of knocking on the axe. From top to bottom, Su Mo looked at it three times and still felt happy.

"From no entry to entry, it is indeed a qualitative leap!"

Take out a unit of wood, Su Mo gently chopped it down, and with a clang, the wood broke.

It was like cutting through the water, and there was no big resistance in the whole process.

With such a "productivity" tool, let alone the axes produced on the assembly line on the earth, even the electric saw may not be so efficient.

"Sure enough, other species have advantages in the body or fantasy side, but humans"

"The advantage of humans 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 the previous one, there is still a more standard way of making.

After a quick review, Su Mo gave up the idea of ​​continuing to learn and try.

People should not be greedy for success and rush into new techniques.

I haven't mastered the teaching just now. It's too easy to force things to grow, and the foundation is unstable, so it's difficult to make progress in the end.

After returning the screen to the beginning, Su Mo sat on the stone bench and closed the door to rest for a while, and then started recording.

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

"Although the picric acid that was hastily made last time was upgraded to the excellent level because of the workbench, it didn't have any attribute bonus. It should be that there was a problem with my steps and preparation methods."

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

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

The reason why picric acid was eliminated is that it is difficult to detonate and explodes at a touch.

Whenever it hits an object violently, picric acid will explode immediately, without any 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 to make mines, lure the enemy up, and use the mines to kill the enemy.

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

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

After figuring out the idea, the next task is only one-preparing a large amount of picric acid raw materials!

Just like in the farming game, you have to rub weapons and ammunition before fighting monsters. Sitting at the workbench, Su Mo patiently completed each step.

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

At each step, Su Mo repeatedly watched the teaching screen on TV and tried his best to achieve the extreme!

With the final addition of the prepared nitric acid into phenol disulfonic acid, after the nitration reaction is completed, fresh picric acid comes out!

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

[Piric Acid Explosives - Trinitrocresol (Excellent)]

Description: A powerful explosive made by entry-level craftsman "Su Mo". It is insoluble 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. Because the preparation method strictly follows scientific concepts, it has reached an excellent level.

Attributes: Melting point 8℃, boiling point: >300℃ (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: If it is well lit, everyone is happy! If it is not well lit, the whole village will have a feast!

"Although the explosion of 300 degrees makes the explosive crossbow a thing of the past, it is the most suitable for making explosive packs!"

Looking at the picric acid explosives of about one kilogram in front of him, Su Mo gently took a small basin and put all the picric acid crystals in it.

For the next half day, Su Mo sat in front of the workbench and repeated this boring process tirelessly.

Every time when Su Mo wanted to give up, he would feel excited when he saw more and more yellow crystals piled up in the corner!

Five kilograms of toluene, plus all the saltpeter he had robbed before, made a total of 30 kilograms of picric acid.

Converted to 60 kilograms of explosives!

With these quantities, Su Mo planned 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 for fixed-point use!

In daily movies, you can often see explosive packs tied like quilts.

This kind of explosive pack is called a group charge. It is made of loose powdered explosives, spread between cloth and paper, wrapped like a package, and then tied horizontally and vertically with ropes.

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

After putting picric acid in the appropriate proportion, wrap it up with cloth, and finally wrap it with transparent tape, the simple picric acid explosive pack is ready.

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

At this point, everything is ready, except for the fuse used for ignition!

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

"Hehe, the manufacturing process of fuses is very complicated, and there are still many things needed, but"

"I have a system!"

When Su Mo thought of the system, he felt refreshed, laughed twice, and directly concentrated his mind and summoned the system interface.

Clicking on the creation interface, Su Mo whispered:

"System, make a simplest trigger fuse, the cheapest one"

[Creation needs detected, mine trigger fuse retrieved, 90 survival points required]

"Mine trigger fuse? What is it?" Seeing the system prompt, Su Mo curiously clicked on the mine trigger fuse card.

A line of description was neatly written on the card:

The oldest mine trigger fuse, 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, tie the falling stone and the steel (iron) wheel at both ends of the rope respectively, and set the rope as a tripwire, and then place the falling stone at a high place.

When a person or livestock trips the rope, the falling stone will fall from a high place, and when it falls, it will drive the steel wheel to rotate, rub against the flint to ignite, ignite the gunpowder fuse, and ignite the mine charge through the fuse.

"1560? This is a trigger fuse from the 16th century?" Su Mo smacked his lips, thought about it carefully, and gave up this ancient trigger device.

Although this device is cheap, it is very practical, especially in the trigger success rate column, which is only 60%, which is extremely unstable.

"Search time after the 19th century, the cheapest trigger fuse"

[Creation needs detected, mechanical pressure fuse retrieved, 99 creation points required]

"Okay! I want this thing!"

Hearing that the price of the pressure fuse is not as high as a bowl of mutton soup and two meat buns, Su Mo's eyes flashed, and he exchanged 5 pressure fuses without hesitation.

495 survival points were deducted, and a green light scattered out, and began to paint on the workbench in front of him!

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, Su Mo can clearly see the generation process of each component inside, and can also clearly see the principle and method of triggering.

Unfortunately, before Su Mo could carefully look at it and remember it, with a bang, the five discs fell on the workbench, making a muffled sound.

Opening the card of the mechanical trigger fuse, after looking at it for a while, Su Mo remembered the complete usage.

This trigger-type fuse, as long as the safety is pulled and placed on the explosive pack, anyone who steps on it will trigger the detonator below, thereby detonating the picric acid explosive pack.

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

One pound of explosives is not enough? I'll give you ten pounds!

What fireball technique, what human sea advantage, will become a joke under the "fire power phobia" of the Chinese people.

"System, how many survival points are needed for a 10-minute time fuse!"

[Creation requirements detected, time fuse (length 10 minutes) retrieved, 20 creation points required]

"So cheap?"

Flipping through the card introduction, Su Mo was surprised to find that the time fuse only needs 2 points per minute, and every minute of extension will increase the demand by 2 points.

After thinking about it, Su Mo waved his hand and directly exchanged 3 10-minute fuses, 5 5-minute fuses, and 15 3-minute fuses.

A total of 200 survival points were spent.

The thing that appeared this time was very simple, like a thin rope, it only needed to be ignited, and it would slowly begin to burn. When the time came, the black powder in the middle of the explosive pack was ignited.

Boom!

Turning his head, looking at the dark sky outside, Su Mo made a boom with his mouth!

"It won't take long"

"Tomorrow morning, let the dog-headed man know what art is!"
