Wizard: I Brought the Wrong System

Although the nitroglycerin has been configured, the follow-up work is not easy.

In general, nitroglycerin also needs to be mixed with diatomaceous earth in a ratio of 3:1 to obtain commonly used yellow safety explosives.

Diatomaceous earth, a kind of khaki siliceous rock, is composed of the remains of ancient diatoms. To the special porous structure, the number of pores is about 5000-6000 times that of charcoal.

Therefore, diatomite is not only chemically stable, but also has an excellent adsorption effect on liquid substances.

Yarrow doesn't know if there are diatoms in this world, or whether the land today was the seabed tens of thousands or hundreds of thousands of years ago, and where to find diatomite, so he can only use his brain on the design plan. .

As for the instability of nitroglycerin, it can be solved by directly installing it in the space ring.

The interior of the space ring is like a balloon pocket, and when something is put in, that part of the space will expand.

The edge of the space can be sensed with mental power, but Yarrow doesn't know what the edge looks like, only that the temperature will not be transmitted or penetrated.

It's just that the space of the entire space ring is one, and the temperature of the internal items will transfer and influence each other, and eventually reach an average temperature.

Yarrow drew a sketch. Since the amount of nitroglycerin is not much, it is necessary to make effective weapons and make full use of them.

The best way is firearms, as Yarrow has already studied.

The first is to borrow the structure of the oil tank and reserve a plurality of partitions and wave shields inside the bomb to reduce the liquid collision inside the bomb.

This design is to prevent the bomb from swaying in mid-air and exploding when the bomb is dropped.

Then it is to engrave the magic pattern inspired by the fire element on the outer metal shell. It doesn't take too much effort, and it is enough to quickly raise the temperature to more than 60 degrees.

The engraved magic traces can evenly split the metal shell into several sharp fragments when it explodes.

One thing, two harvests, somewhat means killing two birds with one stone.

"Wait... Since the magic pattern is used as a trigger, why not draw some patterns and cover up the magic pattern?"

"More patterns can also generate more fragments, and can guide the enemy's thinking like 'fear and coercion'."

"It would be even better if it could make others mistakenly believe that these are 'ordinary' blasting flints."

Yarrow had seen the power of explosive flint.

At the end of the fatal battle with Kernan Naby, Kernan Naby used multiple explosive flints to blew himself up and died.

Judging from the results of the explosion, the damage method of the blasting flint is restrained, like a sudden burst of fire, with magic power and high temperature erupting in a spherical range, but the really effective killing radius is only a pitiful 1 meter.

The grenade is different. The explosion of the grenade is like an exploding hedgehog. The most concentrated damage radius is 5-6 meters.

If the enemy uses grenades to defend against explosive flints, then he can also usher in a huge surprise.

The sputtered fragments are physical attacks, and the damage radius can reach thirty meters!

Of course, the further the edge, the fewer fragments there may be.

Fighting mortals may also maim, injure, and cause attrition.

Attacking Extraordinary may not necessarily be the result.

However, within a range of 5-6 meters, the effects of high temperature, high pressure, fragments... multiple blows will definitely make the victim extremely 'satisfied'.

"The surface layer can use 'fire ant steel'. Compared with ordinary materials, this extraordinary metal can also have a stronger impact on the magic barrier, which is equivalent to adding another layer of magic damage."

'Fire Ant Steel' was the only extraordinary metal in Yarrow's hands, otherwise, 'Magic Disgusting Stone' would be the best choice in his heart.

The 'Magic Disgusting Stone' has a better breakthrough effect on the magic barrier, and the color is also very similar to the blasting flint.

After designing the general plan, Yarrow began to concentrate on production.

The individual structure, aided by the heat-resistant magic hand, is not difficult to make.

When the material is still semi-solidified, Yarrow uses the magic hand to shape it. If the material is 'hardened', it can be heated by thermal fusion. The whole process is similar to kneading a mud ball.

After the rough shape is completed, the magic pattern line and the masked pattern are first carved on the surface of the metal, and then soaked in ice water to cool down.

According to the amount of digested glycerin at this time, Yarrow made a total of five grenade shells, and the capacity of each grenade was almost 160 grams.

Use a syringe to extract nitroglycerin, and inject them one by one into the cooled appliances. After confirming that there is no air inside, seal them with iron nails with a mortise and tenon structure.

When sealing, a little bit of nitroglycerin will leak out, but the shell and digested glycerin have been cooled down, so even if some leaks out, it is difficult to cause an explosion.

Up to now, these grenades have done almost the same except that they have no excitation device.

If you restore them to normal temperature, UU reading www. uukanshu.com smashed to the ground, maybe it could be detonated successfully.

- A bit of the smell of throwing a gun, but it's not impossible.

"The next step is to add magic pattern ink to the magic pattern groove."

Adding magic patterns to the magic pattern grooves does not mean that pouring some magic pattern ink into it is enough.

And in the process of drawing, the spiritual power and magic power are constantly changing and adjusting like the release of spells.

The only good news may be: the activation conditions of nitroglycerin are not high, the heat conduction effect of metal is not bad, and the required heating magic pattern is not too complicated.

Painting the magic pattern, smearing the potion to cure the magic pattern, pouring the ink again to cover the magic pattern, applying anti-rust oil...

A metal ball covered with strange black patterns appeared in Yarrow's hand.

The heating magic pattern and the blasting flint were originally fire magic marks, and Yarrow intentionally leaned the concealed pattern on the blasting flint, and the final product looked a bit similar.

- Much like devil fruit.

Yarrow looked at the finished product just made, and secretly muttered: "I've only seen it a few times, and whoever remembers what a burst flint looks like, it's almost done."

"Maybe it's better this way. If you have some knowledge, you can see the fire magic pattern, but it looks more real."

With the first finished product, just follow the steps for the next four.

…

From yesterday's busy work to this afternoon, when the rain dissipated, the five strange metal spheres were finally finished.

On the corners of the glider, the remaining rainwater fell 'tick-tock'.

Yarrow shoved a mouthful of white bread, and moved the telescope to look at Perrin's territory again.

"The bait is here!"
