Wizard: I brought the wrong system.

Chapter 338 The Bait Has Arrived
Aside from essential combat and living supplies such as armor, gliders, and greatswords, the remaining space wouldn't hold much even if it were all used to store nitroglycerin.

Moreover, without a special ignition method, the impact force of liquid gunpowder will scatter the outer gunpowder, making it difficult to fully exert its power. It must be encased in a bomb to make full use of the liquid gunpowder.

The bomb casing is also a very space-consuming item.

Of course, these liquid gunpowders can also be mixed to make yellow gunpowder.

The steps are incredibly simple; just mix it with diatomaceous earth in a specific ratio.

Diatomite is a yellowish-brown siliceous rock composed of the remains of ancient diatoms. Its main component is amorphous silicon dioxide, and it also contains opal and a small amount of oxides. Under a microscope, a special porous structure can be observed, with the number of pores being approximately 5000 to 6000 times that of charcoal.

Therefore, diatomaceous earth is not only chemically stable (its main component is silicon dioxide), but it also has an excellent adsorption effect on liquid substances (due to its numerous fine pores).

Yaro didn't know if diatoms existed in the world, nor did he know if the land we see today was a seabed tens or hundreds of thousands of years ago, nor where to find diatomaceous earth, so he could only rack his brains on design solutions.

The instability of nitroglycerin can be mitigated by using a spatial ring.

The inside of the spatial ring is like a balloon pocket; it only expands when something is put inside.

The edge of space can be sensed with mental power, but Yaro doesn't know what the edge looks like. He only knows that temperature cannot be transmitted or penetrated through it.

However, the entire space of the ring is a unified whole, and the temperature of the items inside will be transferred and influence each other, eventually reaching an average temperature.

Yaro drew a sketch, and since the amount of nitroglycerin was limited, he decided to make an effective weapon to make full use of it.

The best solution is firearms. Yaro designed firearms when he was in college.

However, due to a lack of tools, firearms could not be made for the time being, and nitroglycerin, being a liquid, was not suitable as ammunition.

Taking all factors into consideration, this liquid gunpowder can only be used to make hand grenades.

Gasoline tankers have baffles inside, which divide the independent space into many small spaces to reduce the collision of liquids.

Liquid gunpowder can draw on this principle.

The next step is to engrave fire-activated magic patterns on the outer metal shell.

"Wait... if we're going to use magic runes as triggers, why not draw some patterns to cover them up?"

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

"It would be even better if people could mistake these for 'ordinary' flints."

Yaro had witnessed the power of the Exploding Firestone.

In the final, desperate battle with Kronan Nabi, Kronan Nabi used multiple exploding flints to self-destruct and die.

Judging from the results of the explosion, the way the Exploding Firestone causes damage is relatively subtle. It's like a fireball that suddenly bursts open, with magic and high temperature exploding within a spherical area. However, the actual effective kill radius is only a pitiful 1 meter.

Hand grenades are different. When a hand grenade explodes, it's like a hedgehog bursting open, with the most concentrated damage radius reaching 5-6 meters.

If the enemy defends against grenades using the same method as defending against exploding firestones, then he will receive a huge surprise.

The splashing fragments are a physical attack, with a damage radius of about thirty meters!
Of course, the closer to the edge, the fewer fragments there may be.

Attacking ordinary people might cause them disability or injury, resulting in attrition.

Attacking the extraordinary doesn't necessarily guarantee a good outcome.

However, within a range of 5-6 meters, the combined effects of high temperature, high pressure, and fragmentation will definitely leave the victim extremely 'satisfied'. "The surface layer can be made of 'fire ant steel,' which, compared to ordinary materials, has a stronger impact on the magic barrier, thus adding another layer of magic damage."

'Fire Ant Steel' is the only extraordinary metal that Yaro possesses; otherwise, 'Demon-Repelling Stone' would be his best choice.

The 'Anti-Magic Stone' is more effective at breaking through magic barriers, and its color is also similar to that of the Exploding Flint.

After designing a general plan, Yaro began to focus on production.

The individual structure, with the aid of the heat-resistant magic hand, is not difficult to manufacture.

While the material is still semi-solid, Yaro uses his magical hands to shape it. If the material 'hardens', he can use a heat-melting technique to heat it up. The whole process is similar to kneading clay.

Once the approximate shape is complete, the magic pattern and concealing design are first engraved on the surface of the metal, and then it is immersed in ice water to cool it down.

Based on the amount of glycerol digested at that time, Yarrow made a total of five grenade casings, each with a capacity of approximately 160 grams.

By now, these grenades are almost finished, except for the lack of a trigger mechanism.

If they were brought back to room temperature and dropped to the ground, they might actually detonate.

—It has a bit of a "snap firecracker" feel to it, but it's not impossible.

"Next, we need to add magic ink to the magic grooves."

Adding magic patterns to a magic pattern groove isn't as simple as just pouring in some magic pattern ink; it requires redrawing it from start to finish, stroke by stroke, without any mistakes.

Furthermore, during the depiction process, mental and magical power must be constantly adjusted and changed, just like casting a spell.

The only good news might be that nitroglycerin has low activation requirements, metals have good thermal conductivity, and the required heating texture doesn't need to be too complicated.

Paint the texture, apply a chemical to harden the texture, pour ink again to cover the texture, apply rust-preventive oil...

A metallic sphere covered with strange black patterns appeared in Yaro's hand.

Both the Heating Magic Rune and the Exploding Firestone belong to the Fire element. In addition, Yaro intentionally made the concealed pattern resemble the Exploding Firestone, so the final product does look quite similar.

—It looks a lot like a Devil Fruit.

Yaro examined the finished product he had just made and muttered to himself, "I've only seen it a few times, who remembers what the exploding flint looks like? It'll be fine as it is."

"Perhaps this is better; those with some knowledge can see the fire-type magic runes, which makes it seem more realistic."

Once you have the first finished product, repeat the process for the next four.

……

Working tirelessly from yesterday until noon today, the five strange metal spheres were finally completed as the rain subsided.

The remaining rainwater dripped from the edges of the hang glider.

Yaro stuffed the last bit of white steamed bun into his mouth, then moved the binoculars to carefully observe the path on the edge of Perrin's territory.

"The bait has been prepared!"
