Through the residual chemical knowledge in his previous life, Luo Ming knew that this exhaust gas must contain a lot of sulfur, which is not at the same level as ordinary exhaust gas, and if he takes a few more breaths, he may die.

Later, he also got four mice and two rabbits to come to experiment, and found that if they were smoked for a period of time, even if they did not die, they would wilt, which showed that it was very harmful.

Sulphur-containing exhaust gases appear to produce acids when exposed to water, such as polluting water sources, and may even cause acid rain.

Luo Ming had never seen acid rain, but he could guess that there would be no good harvest in the land drenched in acid rain.

Luo Ming's population is precious, and the arable land is limited, so it can't withstand such a toss.

And he also knew that the nature of this world itself was also spiritual, and there were some strong people, and even some gods were closely related to nature, so he didn't dare to act willfully.

Of course, Luo Ming didn't think that emitting a little exhaust gas could summon the sky to thunder, and he was not engaged in the industrial revolution, just an earthen blast furnace, and many places around the world were engaged in this...... But that's not a good thing.

So he started thinking about how to deal with it.

Of course, reducing exhaust emissions is the first and foremost option, and it is also a palliative option.

However, in the 21st century, the earth has not completely solved the problem of curing the symptoms, and now it is certainly not possible to achieve perfection, so we can only do our best, and we can cure a little bit.

For example, if you try to filter it with water, maybe you can turn some of the sulfur-containing exhaust gas into acid?

However, what can be done with this impurity-filled acid is another question, and if there is a good way to use waste, at least the average cost can be lower.

And then he has to think about how to reduce the harm of the remaining exhaust fumes to his territory.

After a little consideration, Luo Ming decided to find a place in the Karlo Mountains that was far away from the settlement and where the wind was suitable to build a blast furnace to produce sulfur, so as to let the exhaust gas pollute the uninhabited wasteland or even places outside his own territory as much as possible, and beggar-thy-neighbor.

This can avoid harming one's own territory as much as possible, but the overall damage to the environment will eventually exist.

Luo Ming thought about it for a moment and decided to do something else to make up for it.

It must also be useful to simply do a little afforestation, garbage sorting and recycling, but what Luo Ming is going to do is a big plan...... Unfortunately, this was not possible to implement before the end of the war.

All in all, when returning to China as a whole, the first furnace of sulfur was produced, Luo Ming praised the relevant workers and the person in charge, and then suddenly remembered that it seemed that masks could be made to reduce the harm of exhaust gases, so he taught them this trick.

As for this blast furnace, let's use it for the time being, because it is still wartime, and there is really no time and energy to find a place to build a new blast furnace.

Next, Luo Ming, the doppelganger, rushed back to Carlo Mountain City to meet with several merchant representatives.

One of them, the businessman Saiyi, gambled that Luo Ming could win the war, so he took the lead in calling on a number of businessmen to help Luo Ming deliver precious strategic resources, and even offered to accept credit or Merbrunn coupons.

At this moment, although the war has not lasted to the end, it is obvious that Luo Ming has achieved a great victory, and he will not be easily defeated, and there is even no small hope of winning.

Sai Yi was not complacent, but continued to contact more merchants to participate in the gamble, and today he brought a full bucket of thirty-six kilograms of sulfur, and I don't know where he got it from.

In addition, he also brought a lot of grain, lead, copper, iron, etc. on this trip, in short, this group of merchants led by him was really of great help to Luo Ming.

Luo Ming was even thinking about giving him an official position when the war was over, and hinted that as long as he continued to serve, he could one day be crowned a nobleman.

Although Luo Ming's so-called "nobility" of the aristocracy is not a sneer, it only regards it as an identity and a tool that can be used, which is no different from the "authority", "rich man" and "official" in his previous life.

Other aristocrats may be bound by old pedantic ideas, but he has no problem with this at all.

Of course, if he were to challenge the entrenched aristocratic order, his current strength was too thin...... Although there are not many people who can knight merchants, there are always a few precedents to refer to, which is not too deviant.

This also has the advantage of demonstrating his appreciative attitude towards industry and commerce as the supreme ruler of Schönbrunn.

"But in this case, you have to have a bowl of water...... Let's set another batch of knights, and then hold an internal meeting to discuss how the places will be allocated. ”

At that time, military officers, civil officials, merchants, craftsmen, and even doctors were given a certain number of knighthoods as a way to encourage them.

For most people in this world, knighthood is not just about obtaining a hereditary piece of land and military power, but also that the title of nobility itself has an intangible and expensive value, which is equivalent to giving a piece of land and receiving a double share of gratitude.

As for Luo Ming, he doesn't have this psychological barrier, and the knighthood is naturally a good thing that benefits without expense.

Anyway, what he is going to seal is just a knight, and the knight's level of knighthood, the fief and the people can't use it too much, and he is also ready to replace some of it with a salary, so there is no threat to him to grasp the centralization of power.

When Luo Ming first came to this world, he naturally had a superstitious belief in centralization, but now three and a half years have passed, and there has been a certain change.

Centralization is certainly a good thing, but there is also a degree. Moderate centralization of power can concentrate efforts on big things, and policies and reforms can be implemented quickly, but if power is too centralized, it will also cause problems.

To be honest, how to appropriately centralize power while giving the localities enough autonomy without forming too big a hill and affecting the ruling order.

Luo Ming originally didn't use this knowledge very well, and his Meiquan collar was not big, so he could hold it up to everything.

But after the victory of this war, he will definitely start another expansion, and at that time, even if he becomes a great sword master, I am afraid it will be difficult for him to have enough energy to do everything himself.

If he continues to expand in the future, even if he cultivates to a high level, no matter how many lines he can see, and he can think and calculate at the speed of a computer, and write instructions on official documents at a speed as fast as rapping, I am afraid that it may not be enough.

It's better to start experimenting now, anyway, Luo Ming believes that he won't stop at the position of county guard.

Of course, reaching the level of the county guard is really at the limit, and without any special chance, he can even hit the ceiling in the principality - unless he directly challenges the royal family.

But the grasslands north of Mount Carlo, as well as overseas islands and even the mainland, still have a lot to offer.
