85_85536 is like that, that's it. William went to Baron Otto's study, and then prepared to tell his father this and that with a simple scientific theory.

Of course, you need a good entry point first. And weapons are a very, very good reason.

"Father, you should know something about artillery, right?" William did not sell Baron Otto the idea of a musketeer unit again. Instead, the discussion began on a different topic.

"Well, yes. "It's not clear why William asked, though. But Baron Otto was quite fond of talking about these things in front of him for a while—now, after discovering that his political ability and intrigue were not as good as his son's, Baron Otto's favorite thing to talk about with William was only two things, one was his swordsmanship, and the second was where he had been before, and what it was like.

It was in these two things that Baron Otto could also find some superiority in his son.

After listening to William's question, Baron Otto told him about the various kinds of artillery used by the armies of some of the countries he knew, either in good or strange way, or in strange and bad way. Next, William discussed with him the feasibility of forging his own cannons in his territory, and where to get someone who knew how to forge artillery, or where to buy it.

Under William's control, the discussion gradually extended to the ratio of gunpowder. There was no such thing as nitrocellulose, dry powder explosives, maroon gunpowder and the like in this era. In addition to black powder, it is also black powder. So there is nothing else but one nitrate, two sulfur and three charcoal. And as wars continue to occur, similar to what happened in the previous world, they are also repeated in this world.

"Yes, there wasn't enough saltpeter for gunpowder at that time, and the Visigoths blocked overseas shipping routes, so the Britons at that time came up with a very interesting solution. They set up commissioners to scrape the soil in the toilets of each house to supply the needs of the war. At that time, after the news of this incident spread, it was laughed at by many people in other countries. ”

When it came to this, Baron Otto said it directly as a joke.

"Well, yes. But then again, that kind of thing lasts for a long time, and after a reaction, it can actually form saltpeter. It's a wonderful world. William replied with a smile, and then said, "I heard that overseas, there are some islands inhabited by seabirds. The islands are littered with guano. And then over time, it became a natural saltpeter mine. Have you heard of this, father?"

Looking at William's smiling, inquiring gaze. Baron Otto thought for a moment, and then said uncertainly: "I seem to have heard of it, but I don't seem to have heard of it...... I don't remember exactly what it was...... Let's just have such a thing for the time being. ”

"I see. William snapped his fingers, and then said, "Do you know that, father, plants need to draw nutrients from the land in order to grow." ”

"Of course I know, this is common sense. Baron Otto nodded. At the same time, it was a little strange why William suddenly said this.

"Does my father know what exactly the nutrients the plants absorb from the land?" asked William.

"Well, to be honest, I don't know...... But it should be water...... Right?" replied Baron Otto.

"Father should know. On a battlefield where there have been fierce battles and heavy casualties, the vegetation will become unusually lush?" said William again.

"This ...... I don't quite know - my child, what exactly do you want to say, just tell me. You don't have to beat around the bush like that. At this moment, Baron Otto, no matter how dull he was, understood that William had something to say to him.

"In fact, father, the nitrate needed to make gunpowder is very close to the nutrients absorbed by plants. In fact, it's just a little bit worse. "That is, the composition of the manure, which can be converted into saltpeter, is very close to the nutrients absorbed by the plant...... In the New World, in Atlantis, some barbarians would sprinkle human blood to pray for the crops to grow well - this is indeed a very barbaric act. But surprisingly, their crops, the maize, grew very well, not because of their pagan gods, of course, but because—"

"- Alright, William, say no more!"

Baron Otto interrupted William's words almost hoarsely. This surprised William - his father had always been kind to him before. Even if it was his previous appearance, it was the same if it was a little unsatisfactory. Why did you suddenly start a fire like this today?

This puzzled him.

He looked at Baron Otto, and for a moment he was stunned, not knowing what to say. And Baron Otto, after shouting this, also fell silent. The father and son were relatively silent, and after a long while, Baron Otto sighed, then patted William on the shoulder, and said, "This matter is over here, and there will be no more talk about it in the future." My baby. I know your heart is good. But...... The world doesn't allow that to happen right now. ”

As he said this, he tapped his heart: "Faith." Baron Otto said, "Now the world, even kings and emperors, have to prostrate under the power of the Lord of Radiance. The vast majority of people in the entire world are their believers. What you just said is like a heretical alchemist. My baby. If any fanatical believer hears you say such a thing, then report it directly to the church and you will definitely die. ”

Baron Otto's words startled William - he thought he was plain enough, scientific enough, and euphemistic enough. But I didn't expect it to work......

"I don't think I know about it. Baron Otto was relieved to see that William was afraid, and then said, "In the future, you should not say this to anyone else." Not even Charlotine. Forget about it and be cautious about what you say and do. And don't think too much. Having said this, Baron Otto shook his head, and continued:

"My child, I know you have a good brain, and you always have some whimsical ideas, as well as ...... ideas. ”

"Father, I—"

"Well, needless to say," Baron Otto smiled reluctantly, "no need to explain, after all, you are my son, aren't you?"

“...... Yes, Father. William hung his head slightly, and then reluctantly picked up his interest and talked to Baron Otto about something else. Then he turned around and left Baron Otto's study.

“......”

William, who left the study, changed his face instantly. Even if he didn't have to look in the mirror, he knew that his current complexion must be as ugly as it was.

"Damn, got carried away?" said to himself, gritting his teeth, William walked towards his room. Although before this, he also knew about the suppression of the so-called "technology" by the Church of the Lord of Light. But in the end, he took this step anyway. It was also thanks to him that he came up with this idea, and it was addressed to Baron Otto, the man who would never betray him. Otherwise......

"But ......"

But I'm still not reconciled.

I know it's right, I know it's good for everyone, I know that what I have is the truth. But don't say that you are doing it this way, you are not even allowed to say it. You can't even think about it. This depression, this feeling of grievance, made William feel as uncomfortable as if he was about to die. It was from this moment that he developed a great dislike for the so-called Lord of Light and his so-called Church.

But of course, it's useless to talk about these things now. As Baron Otto said, William now, don't talk about those things, it's dangerous to even think about it. Before it is strong enough to defy the sky, the best thing to do is to go with it, plus close your eyes and plug your ears......

In this way, the construction of public toilets, composting, the establishment of biogas digesters, and the use of manure have all failed. William was sad about this for a long time
