The next day, early morning.
A violent roar woke up all the servants in the castle.
While everyone was panicking, Deputy Butler Dylan walked back to the castle in despair.
"Just now... was that the commotion caused by the wizard?" The horse-faced Old Bard had been keeping vigil at the castle gate, so he also saw Yaro and Deputy Butler Dylan going out together.
"Uh... um!" Deputy Butler Dylan came to his senses and prepared to return.
Horse-faced old Bud looked outside the door and asked in a low voice: "Master Wizard...is he gone?"
"gone."
Hearing that Yaro had left, the horse-faced old Bud, who had been timid just now, suddenly felt emboldened and immediately complained: "How many guards do we have? If the news was not blocked, how many refugees and bandits might be passing by? people?"
"As long as we guard the night, what will happen 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 are still energetic enough to fight during the day?"
Although the horse-faced old Bud had never heard of the saying "You can only be a thief for a thousand days, how can you prevent a thief for a thousand days", but he still knew the similar meaning.
"Why didn't you tell the wizard when he was here?" After putting down the iron ball, Deputy Butler Dylan's tone became much more relaxed.
"How dare I!" Horse-faced old Bud looked out the door with a guilty conscience, turned around and suggested in a low voice, "Dylan, since the wizard has left, why don't we...continue to block the news?"
Forget it is over, there won't be too many people who escape and want to come back. As long as there are a dozen fully armed guards guarding the key points and stopping anyone who wants to return, the news can continue to be blocked.
Deputy Butler Dylan also lowered his voice: "Didn't Master Wizard make arrangements last night? What are you still worried about?"
"Arrangement? Is the rag being assembled on the top of the castle the arrangement?"
Needless to say, the rags Old Bud mentioned were hot air balloons.
As if he noticed that his voice was a little too loud, Old Bud simply broke the jar and threw it.
"Yes, I know, that thing is magical and can fly into the sky!"
"What's the use?"
"Even if we can see many refugees rushing towards the castle in advance, will the guards who keep vigil every day have enough combat effectiveness?"
"Even if all the guards stop keeping vigil, how many of us are there? Dozens of people! With just these people, can we suppress the waves of refugees and bandits?"
"That rag flying high in the sky will turn out to be the most attractive treasure!"
I have to say that although Old Bud usually keeps silent, he does have his own thoughts and ideas.
"The wizard has his own considerations, you... don't think too much about it," Deputy Butler Dylan looked at the shady corner of the corridor, where dozens of weird iron balls were piled up.
Yes, what are the considerations?
Instead of doing something as simple as closing the floodgates, you insist on letting the news get out and let the restless torrent flow out.
Even if so many powerful magical things are left behind, what effect can they have?
…
Thinking of the bomb that exploded just now, Yaro shook his head dissatisfied.
"The power is a bit weak."
Although he had known for a long time that saltpeter with residual ice magic power would affect the power, Yaro did not expect that the power would be so different.
Three kilograms of gunpowder made from unrefined raw materials were placed in a bomb casing that was also added with magic patterns. The explosion power produced was actually not as good as the effect of one kilogram of gunpowder.
"The residue of ice magic is much more serious than the water not being removed."
Thinking of the gunpowder flying all over the sky during the explosion, Yaro took out the experiment diary from the space ring and summarized what just happened.
'So much gunpowder has not been fully burned, which may not only affect the burning effect of the gunpowder. '
'The explosion was a split second. '
'Is it because of the remaining ice magic that caused a moment's pause in the burning of the gunpowder, and the impact that had been generated dispersed the unburned gunpowder? '
'If you think about it the other way around, since ice magic can have a continuous impact on gunpowder during an explosion, can you fill the sulfur with fire magic to make the explosion more powerful? '
Thinking of the principle of gunpowder explosion, Yaro shook his head.
Black gunpowder is a chemical reaction between saltpeter, sulfur, and carbon, which produces a huge amount of expanding gas.
In this process, even if fire magic is added, it cannot increase the gas produced by the chemical reaction. A small amount of fire magic can only make the black gunpowder burn more fully.
But the shell of the bomb designed by Yarrow already had magic patterns and structures that promoted combustion.
A small amount of fire magic power not only fails to enhance the power, but also makes the gunpowder more unstable and increases the risk of automatic explosion.
Even if a large amount of fire magic is added, the cost issue 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 inferior to adding sugar, after all, adding sugar is a multiple change.
Six parts solid produces four parts gas, and twenty-nine parts solid produces sixty parts gas. Anyone knows how to choose.
However, what if there was a better option, like... nitroglycerin?
I think normal people know better how to choose.
Of course, normal people generally don’t know how to do this stuff, but Yaro knows a little bit about it...
It’s just that we are no longer in the previous life, so many basic things need 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 his previous life was a bit old, and Yaro didn't remember much, so he could only keep climbing along this route.
This will inevitably produce a lot of waste and pollution, which can easily expose the production process.
Also because many things have no finished products, the production process takes a long time, and they are not as concealed as gunpowder, so they are 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 Yaro has researched it on the pretext of taste, it has not yet produced a finished product.
——The other ingredients haven’t been made yet, so there’s no rush at all.
Yaro's eyes were deep and he looked far away in the direction of the castle.
"Although the wanted notice issued by Jungle House did not mention the last explosion, didn't those who were following it know about it?"
"Judging from the fact that the wanted poster did not mention the final explosion, it seems that Mentor Bosco took the blame, but the fact that he has the space ring can be clearly seen on the record stone."
"There is a space ring, and he is still the one who caused the explosion."
"Would the wizard who came after me not be aware that I still have the remaining bombs?"
If you understand, you will find out.
In the follow-up, whether it is careless or careful exploration, after all... they will appear.
