Seeing Jiang Yang's expression, Yalong had already accepted his fate.

In any case, drawing a little blood can be considered a bit of compensation, and if there is no compensation at all, it would be miserable.

Seeing Yalong's agreement, Jiang Yang found the position with ease, and then stabbed a needle to draw out a tube of blood.

"OK"

Jiang Yang patted Yalong on the head to show encouragement, and he will do better next time.

"Ang~"

But apparently Yalong didn't want this kind of encouragement.

Jiang Yang didn't care about it rejecting his kindness, anyway, just continue next time.

Back in the box laboratory, Jiang Yang began to put Yalong's blood into the centrifuge for stratification.

Then take out the scrap metal fertilizer and start making rune bombs.

"Among the runes in my hand, the ones that best match the attributes of Yalong's blood should be the high-temperature runes from the ball rune props, but in terms of effect, holy flame runes are better for monsters on the dark side."

Jiang Yang wondered how to make this kind of bomb, not only to have an explosive effect, but also to have additional effects.

"Well, if you want to have the most power, you need to use gunpowder, and use gunpowder as a detonating device."

"The rune should be engraved on the inside and outside of the bomb. The high temperature rune is engraved on the inside to increase the power of the explosion, and the holy flame rune is engraved on the outside to increase the special damage."

"The shell of the bomb should be in the form of a grid, and when it explodes, it can burst according to the predetermined part."

"..."

Jiang Yang wrote and drew on the scratch paper, constantly supplementing the shortcomings.

A qualified bomb cannot just have power.

Safety, convenience, and ease of use are what Jiang Yang pursues, and adding enough power on top of this is the perfect bomb!

After designing the approximate shape of the bomb, Jiang Yang began to think about how to make it.

The source of gunpowder is a bullet, and a rifle bullet is more suitable.

At the same time, the trigger device on the bullet can also be used, as long as an elastic striker is added to it.

When not in use, it is enough to separate the elastic striker and the primer with a gasket.

This also ensures safety, and the source of bullets is more convenient for him now.

The bomb itself is similar to a grenade, with grids on the surface, but each grid is larger, and each small grid must be engraved with corresponding runes.

The high temperature rune is engraved on the inside, and when the gunpowder is triggered, the high temperature rune will also be triggered, which will cause a greater explosion power.

Rifle bullets and metal scraps were gradually formed under Jiang Yang's continuous operation with the [Creator Gloves].

"Hey, just apply the serum next."

Looking at the rune bomb that was basically completed, Jiang Yang was very satisfied.

Soon, the centrifuge stopped, and Jiang Yang took out the serum in the test tube.

The serum is then applied to the surface of the rune, wiped off excess, and allowed to air dry.

After the completion, start to load gunpowder, install the trigger device, and the entire rune bomb is ready.

The entire rune bomb is about the size of a fist. As long as the gasket that acts as a safety device is removed, it can be detonated by throwing it hard at the target.

That is to say, if there is no gasket, even if it is dropped on the ground, it will explode.

"It doesn't seem to be that safe, forget it, who cares about him"

Jiang Yang muttered as he looked at the bomb in his hand, and then prepared to test it.

Of course, before that, he still had to do a good job of safety protection. Jiang Yang deliberately put on his own metal armor, and then put on the bomb and left the box laboratory.

"Go and find a deserted place"

Jiang Yang rode on Yalong's back and said something to it.

"Ang~"

"Push~Push~"

The place where Jiangyang placed the box laboratory is a valley, which is not suitable for testing bombs, and it will be a trouble in case of a wildfire.

Soon, one person and one dragon came to a barren mountain.

Surrounded by bare rocks and no people around, it is a good test site.

"Fly away"

"Ang~"

Yalong tilted his head and couldn't understand what Jiang Yang was thinking, but he did.

Jiang Yang himself found a stone as a protective wall, and then took out the rune bomb.

After removing the gasket, Jiang Yang felt a little uneasy in his heart.

But he still threw it out of the stone!

"Boom~"

As the rune bomb landed, the bomb was triggered instantly, and then exploded with a bang.

Pieces of metal flakes shot out in all directions, and the runes attached to them turned these pieces of shrapnel into white blades.

It's just that the explosion has a stronger impact and a wider range than a bullet, just like a fireworks.

After the explosion, Jiang Yang was slightly stunned when he saw the flying shrapnel.

"The power is enough, but it seems that the effect is not good enough"

Jiang Yang carefully recalled the moment of the explosion and he saw the situation. The holy flame rune didn't last long enough, it just disappeared in a flash.

"Can you find a way to prolong this effect?"

"The effect of the holy flame rune is somewhat similar to that of holy water. Maybe you can mix the serum and holy water."

Thinking of this, Jiang Yang no longer hesitated, and after recalling Yalong, he returned directly to the box laboratory.

Taking out the bottle of holy water from the milk tea pudding, Jiang Yang dropped a drop into the Yalong serum, and the two liquids immediately fused together.

It's just that the mixed liquid turned milky white and looked a lot thicker.

Jiang Yang took out the liquid and rubbed it on the rune metal plate, wiped off the excess, and then baked it with an alcohol lamp.

"呲~"

The dazzling white flame suddenly ignited, and it seemed to be more dazzling than the previous test, and the duration was slightly longer.

"One second more than two seconds"

"enough!"

Seeing the effect of the mixed solution, Jiang Yang smiled with satisfaction, and then started to recreate the rune bomb.

This time, I made several more in one go. With successful examples, it is much easier to get started.

In the end, Jiang Yang brought these bombs to the barren mountain again for testing~lightnovelpub.net~ This time the effect will be much better.

As long as the shrapnel of the bomb hits the monster, it can definitely cause additional attachment damage, if he throws ten or eight rune bombs in one go.

Hey, that picture is too beautiful to imagine.

And the rune bomb with such a good effect should not be expensive to buy 50 points, right?

And what is the cost of making a rune bomb, two rifle bullets, some scrap iron.

Argon serum and a drop of holy water can make dozens of rune bombs at a time.

Therefore, if you only calculate the cost, a rune bomb will not exceed five points if you calculate it too much.

With ten times the profit and a lot of points, Jiang Yang can buy gems, buy magic metal, buy rune props, and support his own rune research.

In an instant, Jiang Yang thought of a lot, and the next development route was about to be planned.

Alas, thinking about it like this, the days to come seem to be getting better.
