In the Taiwan Strait, three ships of Columbus's fleet are cautiously exploring northward along the west coast of Taiwan Island. Previously, when sailing along the coast of Guangdong, the fleet also found fishermen to inquire and went to a place called Crescent Island.

Why go to that Crescent Island? This was specifically commanded by Marin. The name Crescent Island is not famous, but when it comes to Dongsha Island, there must be many Chinese people in later generations who know it. There are four sands in the southeast, northwest and northwest, and only the Dongsha Islands are under the control of Taiwan Island.

Dongsha Island is not large in size, there are no hills on the island, not even mud, only coral crushed sand, and it is a standard coral reef. Because it is a coral semi-atoll, like a crescent moon, it was called Crescent Island by the Ming Dynasty.

There is no fresh water on the island, so there is no permanent population, only a few dilapidated houses, which are temporary stops and rests for fishermen along the coast of Guangdong.

And Ma Lin, the reason why he is interested in this Dongsha Island, is because there is the most important strategic resource in the agricultural era on Dongsha Island-struvite stone......

According to the historical articles that Marin read in his previous life, in 1901, a Japanese businessman named Yoshiji Nishizawa drifted to Dongsha Island by chance, and found that the island was full of struvite stones, which were as thick as 15~20 feet, that is, 4.5 meters and 6 meters thick. The land area of Dongsha Island reaches 1.8 square kilometers, so you can imagine how many struvite there are......

Struvite is a substance formed from guano and is certainly rich in nitrogen. At the same time, because it is pulled by seabirds, it is also rich in phosphorus. Because, seabirds eat sea fish. Moreover, the sea fish eaten by seabirds eat aquatic plants in many things, and aquatic plants contain potassium. Therefore, struvite is a natural fertilizer that contains three major fertilizer elements: nitrogen, phosphorus, and potassium at the same time.

In the future, if Marin wants to develop Taiwan Island, it will definitely be inseparable from fertilizer. It's not cost-effective to transport fertilizer from the mainland. Therefore, it is better to dig struvite as fertilizer on site. Dongsha Island, on the other hand, was booked as a fertilizer mining base by Marin.

Originally, Ma Lin also planned to use the struvite fertilizer on Dongsha Island as a bargaining chip to dedicate it to the Ming Dynasty. However, after careful consideration, Marin decisively gave up.

Why? It's not that he is reluctant, but he is afraid of the serious consequences that this will lead to.

Why? Because, the Ming Empire was a standard agricultural empire. This empire, perhaps, did not value commerce and seafaring, but definitely attached importance to agriculture.

And struvite is a treasure, if it is known by the Ming Dynasty, God knows what kind of enthusiasm the ministers of the Ming Dynasty who have countless good fields in each family will burst out.

In this way, Marin may personally light up the great navigation skills of the Ming Dynasty. And once the rich and powerful Ming Dynasty has made a great voyage, then Marin is still a P?

If you travel through the Ming Dynasty, Ma Lin will definitely light up the great maritime enthusiasm of the Ming Empire through the strobs of Dongsha Island. If you tell the officials of the Ming Dynasty about the profits of the Great Navigation Trade, those Ming civil officials who value agriculture and suppress commerce will definitely form a group to spray you to death - the gentleman does not say profit, how can you get into the eyes of money?

However, in another way, tell the civil officials of the Ming Dynasty that going overseas and looking for struvite can double the yield per mu of grain...... What's the matter, if anyone dares to object, they will be sprayed as dogs by everyone - what? You don't want to double your yield per acre? What do you still want the old man to do...... Food was a major event in the feudal dynasty......

And in the Ming Dynasty, which minister didn't have a thousand acres of fertile land at home? The search for struvite is in the interest of all ministers, and there will be no opposition at all. The only question is how to distribute struvite ......

Therefore, Ma Lin believes that he has seen the passage through the Ming Dynasty and used commerce to lure everyone to engage in great voyages, which is simply not understanding the social environment of the Ming Dynasty at that time. Those civil officials in the Ming Dynasty certainly paid attention to interests, but they had better face. You lure them with low commercial profits, and you may not succeed. After all, literati are also disciplined. But it is the safest and most direct way for you to use the major event of increasing grain production that affects the country's capital to promote the great voyage of the Ming Dynasty. In order to obtain fertilizer, the agricultural Ming Empire would burst out with unimaginable enthusiasm...... Neither reformists nor conservatives will oppose it......

……

Of course, that's what a time-traveler who travels to the Ming Dynasty should do. As a German prince, if Marin told the Ming Dynasty such a secret, then he would be brainless. After all, unleashing the tiger of the Ming Empire to snatch the cake of the Great Voyage, what will Marin eat by himself?

Therefore, Ma Lin's plan is to take advantage of the Ming Empire's lack of attention to maritime interests, quietly control Dongsha Island, and dig up struvite on the island to use on Taiwan Island......

……

After finding out the location of Dongsha Island, Columbus wrote down the coordinates of Dongsha Island. Then, commanding the flotilla, continue to sail northeast. Once you get close to the island, start sailing north along the west coast of the island.

When passing near the Penghu Islands, the fleet did not alarm the Penghu Inspection Division. After all, they came to seize Dongfan Island, and they were a little unspeakable, so they naturally didn't want to alarm the Penghu defenders of the Ming Dynasty.

In fact, it was also difficult for the defenders of Penghu to spot Columbus's fleet. Because, the distance between Penghu Island and the main island of Taiwan Island has reached more than 40 kilometers. The Ming army did not have binoculars, and Columbus's fleet sailed close to the west coast of Taiwan Island, so at such a distance, of course, the Ming army could not be seen by the naked eye.

After passing through the area near Penghu Island, both Columbus and Conté breathed a sigh of relief. Then, the unobtrusive Columbus invited Conté to play with dozens of Malay girls he had received from the Sultan of Malacca. The girls were miserable, and when they boarded the ship in Malacca, there were 50 of them, but now, only 34 remain. Of the remaining 16 people, 6 died of illness because they were not adapted to life at sea, and the remaining 6 were simply tossed to death by Columbus and sailors.

These little girls were originally very small, and their bodies had not yet opened, so it was okay to be violated by the villain Columbus, and they were shared by Columbus with the sailors...... The girl who died first was tossed to death after receiving 12 sailors in one go......

Both Conté and Sconda had been educated by Marin's ideas of modern civilization, and they were very unaccustomed to Columbus's behavior as a young child. However, he is not as good as Columbus in identity, and in this era of strict hierarchy, he is not good at teaching Columbus anything, so he can only pretend not to see it.

In fact, during the time when he was in the Qinglou in Guangzhou, because he had a lot of fun, Columbus's body was already very prostration. After all, it was a high-end Qing building, and the female branch girls in it were all beautiful. The point is, the skin is very white...... If it weren't for the difference in hair and eyes, as well as the nose, Columbus would have treated them as white beauties......

The swarthy Malay girl of Columbus Company is willing to go, let alone the snow-white and pink high-end Qinglou female branch girl? Therefore, as soon as Columbus was excited, he lost his kidney......

But it doesn't matter, after passing the scope of Penghu Island, Columbus is in a mood and plans to abuse those Malay girls again.

It's just that his kidneys are not good now. Although Kong Tai prescribed a bunch of kidney tonic medicines including ginseng and deer antler velvet for him to take in Guangzhou, the important effects came slowly, and Columbus had not yet recovered.

What to do? Columbus, the old silver worm, had his own way, and when he saw him carefully take out a box, and after opening it, he took out a small porcelain vase very preciously......

Although Conté did not accept Columbus's suggestion to be happy together, he was curious about the small porcelain vase that Columbus took out. Obviously, this is something that Columbus got in Guangzhou. After all, there are no porcelain vases in Europe. Moreover, looking at Columbus's very precious appearance, it seems to be a good thing......

"Lord Columbus, what is this?" Kong Tai asked curiously.

"Haha, good stuff. With this thing, I can immediately reinvigorate the man's majesty......" Columbus said lewdly. Obviously, this porcelain bottle contains a medicine for fun.

"Where did this thing come from?" Conté asked.

"Of course, I got it from Tianxiang Building (the high-end Qing Building where Columbus stayed for a long time)!" Columbus said proudly.

It turned out that in the later part of Columbus's stay in Tianxianglou, he had some kidney deficits. But the old bustard still expected him to continue to spend money with the girl, so he gave him a few bottles of medicine to help him continue to consume.

Columbus proudly held up the small porcelain vase and said:

"This is called 'Yangdingtian', which is made of many precious medicinal materials and is worth thousands of copper coins. With it, I can 'love' those little girls for more than 30 minutes......"

"Good girl, such a powerful ......" Kong Tai smacked his tongue a little. It's not unusual to last 30 minutes, but it's not unusual for an old man like Columbus who has kidney deficits. You know, Columbus is 55 years old......

"No, Master Columbus, I didn't arrange a translator for you, how did you communicate with those Ming mothers?" Kong Tai remembered that he seemed to have just thrown a few large silver ingots to Qinglou's mother Sang, and ignored Columbus.

"Well, you know, I also know a little bit of Arabic (before, in order to find a route to India, Columbus studied Arabic for a while. In Calicut, India, Columbus also communicated with the locals through Arabic. After all, there are a lot of Arab businessmen in Calicut, and there are a lot of Arabic people over there). It just so happened that the chief secretary of the Ming Dynasty assigned me an interpreter (translator) who knew Arabic, and then I took him to gallop in the Qing Building......"

"......I see," Kong Tai suddenly realized. The Ming Dynasty also had dealings with Arab merchants, and it is not surprising that there were interpreters who understood Arabic.

Then, Columbus took out another porcelain vase and proudly introduced:

"This is called 'Yuyi Girl Becomes a Fierce Sister-in-law', and it is also a miracle medicine given to me by my mother Sang. After eating this, even a cold woman will become enthusiastic...... It's a pity that these little girls are too young and have not yet developed, so it is useless to eat them...... However, back in Las Vegas in the North Sea, I can use it on those hairy girls...... Hey hey ......"

Kong Tai was speechless......

"This one is called 'I love a piece of firewood', and it's even more powerful......"

"This is called 'Tianzhu Divine Oil'......"

"It's called ......"

……

Finally, Columbus pulled out a red porcelain vase. He first shook his head for a moment, and then said:

"This doesn't seem to be of much use, it's called 'sterilization'. Mother Sang said that it seemed to be eaten by the female branch girls, so that they would not get pregnant no matter how they got it, and it was permanent...... Like, it's useless to me......" After saying that, he was going to throw it away.

"Don't!" Conté first froze for a moment, then suddenly screamed, and snatched the little red porcelain vase directly from Columbus's hand......

Why? Because when Ma Lin taught Kong Tai Chinese, he casually said, "If only there was a bottle of medicine for a woman to eat, she would never get pregnant", and also said, "This kind of medicine is probably only available in Daming"...... Then, Comté remembered......

However, before this departure, Marin did not instruct (probably forgot) Kong Tai to find this drug, and Kong Tai did not think to look for it.

Now, Columbus took out this medicine and planned to throw it away, but Conte suddenly remembered, and then snatched the drug and planned to take it back and give it to Marin......

"What do you want this drug for? Don't you want offspring? "There's something strange about Columbus.

"It's a secret...... By the way, does this drug smell after eating? Will it feel it? Conté did not answer, but asked Columbus rhetorically, changing the subject.

Columbus thought for a moment and said:

"Mom Sang said that this thing is colorless and tasteless, and I don't feel it when I eat it. There are no side effects for men, but if women take it for seven days, they will be weak and sick for a few days. Then, the water of the sunflower becomes light, and from then on it is no longer fertile, but it does not affect the woman's emotion...... In other words, what is this geranium? ”

Kong Tai had studied Chinese, so he naturally knew that it was the civilized name of the menstrual affairs, but he didn't bother to explain it to Columbus, but treasured the bottle of "sterilization powder" and carefully hid it, planning to bring it back to Marin......
