Marin was as fierce as a tiger, but before signing the contract, he found out that he was a two-hundred-five!

Nima, as the king, is going to sign a contract to collect dung, which is a shame to be thrown out of the solar system! The kings signed armistice agreements, trade agreements, and no matter how bad they were, they were peace agreements. On the first day of becoming king, he signed an agreement with someone to collect dung...... This is to be nailed to the pillar of shame......

Therefore, at the last moment, Marin came to his senses and refused to sign the contract as the "King of America". Of course, it is impossible not to sign a contract. Therefore, he directly dragged out Karn, the number one bodyguard who stayed by his side......

"What? The lord ...... "Karn, who was wandering, was puzzled. He doesn't like to use his brain, and when everyone is arguing, he has long been out of the world.

"You, on my behalf, sign an agreement with these nobles to collect dung!" Marin looked serious.

When Karn heard this, his whole person was not good, and his head shook and almost fell:

"I don't! I don't! Please be smart about this! ”

Nima, labor and management are also the number one fierce general of the Beihai Kingdom, and the earl of the Grand Duchy of Beihai! actually signed the contract for collecting dung, doesn't this bury people?

However, the subordinates brought by Marin this time, except for his own family of three, Karn was a great nobleman who could be put on the table. The others are guards and the like, so they can't be representatives at all......

Finally, Marin thought of a solution, and he said to Karn:

"I won't let you sign in the name of the nobles of the North Sea Country, but on behalf of the Blackwater Company! I remember, you're the manager of Blackwater, right? ”

Blackwater Company is a leather bag company specially created by Marin in order to lend troops to allies. The scope of its business is to provide mercenaries to help people fight. Marin is the owner of Blackwater, and Karn is Blackwater's security manager......

Karn wanted to refuse, but Marin was furious:

"Do you want me to sign this agreement myself? I recruited you, and you won't help me carry this little thing? Besides, it's not dangerous...... Bala Bala Bala ......"

Marin flickered and pressed Karn with the name of righteousness. Karn wasn't very smart, and was stunned by Marinkan. He felt that if he stood up again to help Marin sign, he would probably be called an unfaithful rebel...... And for a pure martial artist like Karn, the name of loyalty and righteousness is very important. Then, the goods plucked up the courage and went to sign a contract.

Of course, before signing the game, Marin advised:

"Don't sign the title and the title of the officer's position, just write 'Blackwater Company Security Manager Kahn'......"

Karn understood, and did so......

Of course, other monarchs and nobles were not stupid, they all sent their men to sign, and no one signed the purchase contract involving excrement themselves. It's too embarrassing to be without him......

But Marin was still ashamed, after all, this was the first agreement he had personally negotiated with the monarchs and princes of other countries after he was crowned king. I didn't sign it myself, but I talked about it myself......

Later, a meme that has been popular in Europe for hundreds of years is-

"Alright, let's get down to business, let's stop talking nonsense. Do you want to be like Marin the Great and talk about things like collecting dung on the first day of his ascension? ”

Then, both sides of the negotiation generally burst into laughter, and even the atmosphere became much more relaxed......

……

Of course, Marin doesn't know this stalk yet, otherwise he would have to vomit blood. How did he know if he had sent Karn to the top of the thunder and still compensated himself......

There were quite a few monarchs and princes who signed agreements with Marin this time, involving more than 150 cities on the Rhine, Weser, Elbe and the Netherlands. It's not that these cities are the only ones who have the intention to cooperate, but that other cities that have the intention to cooperate do not have transportation conditions.

After all, manure is too cheap. If the high-cost horse-drawn carriage transportation by land is used, it is estimated that the cost will not be recovered. Therefore, cooperation is only possible in cities close to the Rhine, Weser and Elbe, which are easily accessible by water. Because, the volume of shipping is large and the cost is low.

In everyone's opinion, although soil nitrate can be extracted from manure, the extraction rate is really low. A pool of feces can be extracted from the corners and corners. Moreover, cold weather is needed for frost to form nitrate. So, no one thinks it's profitable.

How did they know that manure itself is a nitrogen fertilizer resource. Even if it wasn't used to extract nitrate, Marlin could turn it into more food. And even if it is to extract earth nitrate, Ma Lin can extract eight or nine catties of fire nitrate for every 100 to 150 catties of urine or thin feces learned in his previous life.

The specific method is to use 1,000 catties of fluffy sand-containing fluvial soil, and 100 catties to 150 catties of urine or thin manure to ferment in an environment of 26 channels and 28 degrees for more than 20 days, and then mix the soil containing nitrate and plant ash (ratio 8 to 1), and then soak it in hot water of seventy or eighty degrees to dissolve the saltpeter components into hot water. After filtration, evaporation and condensation, saltpeter can be obtained that can be used to prepare gunpowder.

That is to say, using the methods of later generations, the extraction rate of saltpeter is as high as six to nine percent. The core, of course, is that the cost of nitro is mainly in urine and loose feces. And many of the unpleasant smells we usually smell in toilets are nitrogen-containing ammonia components. Therefore, Marin emphasized with these customers - as long as the manure is thin, do not dry and hard......

Sadly, with traditional methods of extraction, the extraction rate of saltpeter is not even 6 per thousand. Even, less than one in a thousand.

There is no way, the traditional method only scrapes the soil in the corner area of the pool. With modern extraction methods, the entire soil is directly packaged and purified. The proportions are completely incomparable.

……

Although most of the 150 cities that cooperated with Marin were small towns with two or three thousand people, and few had more than 10,000 people (the population of more than 10,000 in these years was considered a big city), they added up to a total of hundreds of thousands of people, and hundreds of thousands of pounds of feces were produced every day.

This manure is collected and extracted by modern methods, and tens of thousands of pounds of saltpeter can be extracted, to the least. And in a year, Marlin can harvest at least half a year (and in the other half of the year, in cold weather, those areas will extract saltpeter on their own), that is, about 1.8 million pounds of saltpeter can be extracted......

Marin felt a little frightened at this number. After all, it's really not a big cost. After all, those cities were half-sold and half-given to Marin.

They were frightened by the "hygiene" doctrine introduced by Marin, and they were afraid of the spread of diseases, so they did not ask Marin for a high price at all. If it weren't for the ability to extract nitrate, they wouldn't even ask Marlin for the wages of the "sanitation workers" who collect the manure.

Of course, Marin is not without paying. For example, in the early stage, Marin needed to provide those cities with a batch of sealable "toilets" that were specially designed to carry feces for free. After all, this thing is too smelly to be shipped in bulk, so it can only be shipped on a sealed toilet.

In addition, Marin plans to pay for the construction of a number of public toilets in these cities to facilitate the collection of excrement. Ma Lin even plans to go to the cement public toilet to prevent fecal water from seeping into the ground through the soil.

What the? You say that the citizens of this era will not follow the rules and go to the toilet honestly? It doesn't matter, Marin has already given the solution that the monarchs and princes like very much - fines!

Whoever dares to do anything anywhere in the city will be fined! The reason is that Marin proposed "spreading the Black Death and other evil diseases", which is above board!

In fact, the monarchs and nobles didn't care if it was true or not. They only care - finally found an excuse to loot money from civilians! So, don't worry that they won't be strictly supervised. For that fine, these people will stare at the common people like mad dogs. It is conceivable that in the future, it will be difficult for such a bad situation to appear in German cities.

Marlin, on the other hand, can also take the opportunity to collect enough saltpeter raw materials, and an annual output of one or two million pounds of saltpeter is not a problem. Even, the scraps of saltpeter can be used as low-quality fertilizer (saltpeter is the main component of fertilizer, and the fertility of the remaining manure will be greatly reduced if saltpeter is extracted)......
