Wizard: I brought the wrong system

The next day, early morning.

A violent roar woke up all the servants in the castle.

While everyone was terrified, Dylan's deputy butler walked back to the castle in a daze.

"Just now... Was that the movement made by the wizard?" The horse-faced old Bud had been keeping watch at the gate of the castle, so he also saw Yarrow and Dylan's deputy butler go out together.

"Uh...um!" Dylan's deputy housekeeper came to his senses and returned in a hurry.

The horse-faced old Bard looked outside the door, and asked in a low voice, "Master Wizard...has he left?"

"gone."

Hearing that Yarrow had left, the horse-faced old Bud, who had been cowering just now, suddenly gained confidence, and immediately complained: "How many guards do we have? If we don't block the news, how many refugees and bandits may pass by?" people?"

"What are you talking about, as long as we keep watch at night, what if the refugees suddenly attack the castle during the day?"

"There are only a few guards in total, and most of them have gone to watch the night. How many of them can have the energy to fight during the day?"

Although the horse-faced old Bud had never heard the phrase 'Only a thousand days to be a thief, how can a thousand days to prevent a thief', he still knew the similar meaning.

"When the wizard is around, why didn't you tell him?" After putting down the iron ball, the tone of Dylan's deputy butler became much more relaxed.

"How dare I!" The horse-faced old Bud looked out the door with a guilty conscience, turned his head and suggested in a low voice, "Dylan, since the wizard has left, why don't we... continue to block the news?"

Forget what has passed, and there will not be too many people who escape and want to come back. As long as there are more than a dozen fully armed guards guarding the key arteries and stopping anyone who wants to return, the news can continue to be blocked.

Dylan's deputy butler also lowered his voice: "Didn't the wizard make all the arrangements last night? What are you still worried about?"

"Arrangement? Is the rag being assembled on the top of the castle an arrangement?"

It goes without saying that by old Bud's rag he meant the balloon.

As if noticing that his voice was a little louder, Old Bud simply smashed the jar.

"Yes, I know, that thing is so magical, it can fly into the sky!"

"What's the use then?"

"Even if we can see many refugees rushing to the castle in advance, can the guards who keep watch every day have enough fighting power?"

"Even if all the guards are not on guard, how many of us are there? Dozens of people! Can this few people stop the waves of refugees and bandits?"

"That rag flying high in the sky will be the most attractive treasure at that time!"

It has to be said that although Old Bard usually does not say a word, he does have his own thoughts and ideas.

"The wizard has his own considerations, you... don't need to think about it," Dylan's deputy housekeeper looked at the shady corner of the corridor, where dozens of weird iron balls were piled up.

Yes, what considerations can there be?

Don't do simple things like closing the gate, but let the news go out, let the torrent of restlessness vent.

Even if so many powerful magical things are left behind, what effect can they have?

……

Thinking of the bomb that exploded just now, Yarrow shook his head dissatisfied.

"The power is a bit weak."

Although it has been known for a long time that the saltpeter with ice-type magic power will affect the power, Yarrow did not expect that the power will be so much worse.

Three kilograms of gunpowder made from unpurified raw materials was packed in the shell of the bomb that also added magic patterns, and the explosive power produced was not as good as that of one kilogram of gunpowder used to be.

"The remnants of ice-type magic power are much more serious than water that has not been removed."

Thinking of the gunpowder flying all over the sky during the explosion, Yarrow took out the experiment diary from the space ring and made a summary of what happened just now.

'The fact that so much gunpowder has not burned fully may not just affect the burning effect of the gunpowder. '

'The explosion is an instant thing. '

'Is it because of the residual ice magic power that the gunpowder paused for a moment while it was burning, and the impact that had already been produced dispersed the unburned gunpowder? '

'If you think about it the other way around, since ice magic power can have a continuous impact on gunpowder when it explodes, can you fill the sulfur with fire magic power to make the explosion more powerful? '

Thinking of the principle of gunpowder explosion, Yarrow shook his head.

Black powder is the chemical reaction of saltpeter, sulfur, and carbon to produce a huge amount of expanding gas.

In this process, even if the magic power of the fire system is added, the gas produced by the chemical reaction cannot be increased. A small amount of magic power of the fire system can only make the black powder burn more fully.

But the shell of the bomb designed by Yarrow already added magic patterns and structures to promote combustion.

A small amount of fire magic power not only cannot strengthen the power, but will also make the gunpowder more unstable, increasing the risk of automatic explosion.

Even if a large amount of fire magic is added, the cost and the automatic activation of gunpowder are not considered.

——Is that thing a bomb, or an exploding flint?

This physical addition makes no sense.

It is far worse than adding sugar, after all, adding sugar is a multiple change.

Six parts solid makes four parts gas, and 29 parts solid makes sixty parts gas, anyone knows how to choose.

Still, what if there were better options like... nitroglycerin?

Presumably normal people know how to choose.

Of course, normal people generally don't know how to make this thing, but Yarrow knows a little bit...

It's just that it's not in the previous life after all, and many basic things have to be done the same.

For example, use sulfur to make sulfuric acid, use sulfuric acid and saltpeter to make nitric acid, use vinegar to extract acetic acid, and then get glycerin...

The memory of the previous life is a bit long, and Yarrow doesn't remember much, so he can only climb along this route.

This is essential to generate a lot of waste and pollution, and it is easy to expose the production process.

It is also because many things are not finished, and the production process takes a long time, and it is not as subtle as gunpowder, so it is not suitable for production in the academy.

But here, no one cares about him.

It's just that there is no condiment like vinegar here. Although Yarrow has researched it under the pretext of taste, he has not yet produced a finished product.

——The other raw materials have not been made yet, so there is no rush.

Yarrow's eyes were deep, and he looked in the direction of the castle.

"Although the arrest warrant issued by the Jungle House didn't mention the last explosion, didn't those who tracked it know about it?"

"Judging from the fact that the arrest warrant didn't mention the final explosion, it should be Bosco's instructor who took the blame, but the fact that he has a space ring can be clearly seen on the recording stone."

"There is a space ring, and it is still the person who caused the explosion."

"Will the wizards who are following me be wary that I still have the remaining bombs?"

As long as you understand, you will find out.

In the follow-up, whether it is careless or careful investigation, in the end...they will appear.
