In addition, it is the learning of how to avoid problems such as crew illness on the ocean, and it is at this time that Zhao Qi knows that there are many problems that he has ignored, so after the end of the contact in the past half a month, when Zhao Qi and they returned to the port to replenish all the supplies, Zhao Qi quickly returned to the port and hired three doctors with high salaries.

If it weren't for Zhao Qi's special status, it would be a little difficult for them to hire doctors, at least it was not easy to hire excellent doctors, but Zhao Qi's experience was a wake-up call for the Han government, and they had to give a wake-up call to other merchant ships on the sea.

For example, the most susceptible scurvy in the ocean, that is, the lack of vitamin C, if no one has studied it, it is difficult to find, Columbus, Magellan and others in history in order to deal with scurvy, and even superstitious began to eat rats to cure diseases.

But in the end, nothing came of it, and it was not until more than 200 years later that the secret of scurvy was solved, and before that, they only found out after a long experiment that eating oranges and other fruits could cure scurvy, but as for the reason, they did not know at all.

Although Zheng He and other Chinese people in history have also been to the West, they have not been affected by scurvy, in fact, there is a reason for this, as for some of the so-called bean sprouts to treat scurvy in later generations, it is all nonsense.

Bean sprouts certainly have some vitamin C in them, but the content in bean sprouts is not much, and secondly, at sea, fresh water is a more important resource than food! Because the food can also be solved by fishing directly, but in addition to storing fresh water by itself, fresh water can only solve part of the fresh water when it rains.

For the ocean-going fleet, fresh water is the most important resource, people can never live without water, how can it be possible to use precious fresh water to sprout? If you can sprout bean sprouts, wouldn't it be better to grow vegetables directly at sea? For example, wouldn't it be better to eat vegetables that can be eaten repeatedly, such as leeks? After all, these things can be grown in some wooden pots.

The reason why scurvy is not recorded much in China is because Zheng He and other ocean-going fleets, as long as they study it, know that they are walking very mature routes, and there are various ports along the way to replenish supplies, fruits and vegetables, etc.

And in ancient times, it can be said that going to sea at that time would bring huge profits as long as you can operate, but Zheng He went to the West seven times not only did not earn a penny, but spent a huge amount of money, so you can imagine how extravagant the supplies on the road were.

Even if it is not extravagant, there must be no shortage of supplies, so they have no record of scurvy.

And like the Age of Discovery, the places where those people went were barren and inhabited places that they had never been to before, so they were plagued by scurvy, but it didn't matter, now that the Han knew the principle of scurvy, this disease would naturally not affect the Han fleet.

Note that the malnutrition disease caused by vitamin deficiency is scurvy and not sepsis, which are two completely different diseases, sepsis is a blood disease caused by the invasion of viruses into the blood, which is completely different from scurvy.

After hiring three doctors and purchasing enough supplies, Zhao Qi and the other fleet set off directly.

And this time when he went to sea, when he was about to go to sea, because Zhao Qi's ship did not add a new crew, and each ship had a crew of more than 300 people, so in the end, Zhao Qi simply asked the above again, and the personnel on the two ships were increased to 600 people, and the extra people were naturally the personnel in the Xuanwu Army who were ready to turn into the navy.

Anyway, now they have no other place to train for the time being, it is better to follow Zhao Qi to train here, and Zhao Qi's goal on the way is not a deserted place, there are places on the road to replenish fresh water and other supplies, so Zhao Qi is not worried.

In addition to the necessary supplies, Zhao Qi and the others carried enough weapons and armor, but these things were placed on the bottom floor of the warehouse, and the bows and arrows used on the ship were indispensable.

In addition to these things, it is the current silk, porcelain, tea, spices and other very valuable goods in the West, but these things are not carried much, this time mainly to explore the way.

When these things were ready, Zhao Qi and they went directly on the road without hesitation, when they left the harbor this time, the time had already entered the lunar month, and it was already the New Year in more than 20 days.

However, because it is very warm here, Zhao Qi and they don't feel the arrival of the New Year at all, but these don't matter, now their attention is not above the New Year at all, Zhao Qi now has an idea, before the ninth year of the Han Dynasty, how can he have to make achievements.

And from here, they set off to the first island of the Arabian Peninsula that Zhao Qi has his sights, which is actually not very far, it is only less than 1,000 kilometers away from their Zizhulin Port, and their current speed can reach about 10 knots, 18 kilometers per hour, that is, about 60 hours to arrive.

It took less than three days, but because they were going to sea for the first time, the road was relatively slow, but they could definitely arrive in five days, and the previous half a month of training made them very familiar with the performance of their two ships.

Especially for Liu Heima, these old fishermen are actually very morale-boosting, they have found that their boats are very strong in the ability to resist the storm, and the strong ability to resist the storm means that they have a low probability of encountering danger, and they naturally work harder.

After all, they used to worry about danger, but now they hardly have to worry about any danger.

Now it is almost impossible for them to encounter any danger if it is not an extreme situation, and on the sea, as long as the danger of the sea is reduced to a minimum, other risks are nothing at all, because such a ship is invincible on the ocean.

Along the way, they encountered many Persian merchant ships, and when they saw their ship, they were already stunned.

In about five days, when the distant island finally appeared, Zhao Qi also took a deep breath, he directly waved his hand and said: "Release the boat, let them lead the way, we have never been to the route of this place, and the Persians have basically never been to this place."

Because it is so close to Persia, most of the Persian merchant ships have just left the port and arrive here directly, so they will basically not stay here, but will continue to move westward, in fact, most of the Persian merchant ships have almost not gone west.

Because of the war between Byzantium and Persia, in fact, the Persian merchant trade has now dropped to the freezing point of history, and a hundred or two hundred years ago, the Persian merchant trade almost reached the peak of history, at that time, many of their merchant ships were in two places, one was in the direction of the Persian Gulf, and more in the Mediterranean Sea and the Black Sea.

Now the number of these merchant ships is very small, and most of the merchant ships on the Persian Gulf are also going to the Ring Sun Dynasty, of course, there are also small merchant ships trading between the Persian Gulf, but these merchant ships do not have the ability to trade in the ocean.

The small island that Zhao Qi has taken a fancy to is not valued at all.

And Zhao Qi Although they are not the first ships to arrive here, they are also the first to try to dock here, because this island is too close to the Arabian Peninsula next to it, and other merchant ships that come here, even if the fleet wants to dock, they choose the port of the mainland, where they can get more replenishment, and there is no hair on this island.

There were only a small number of residents who had fled to the area, so naturally these merchant ships would not come.

Zhao Qi and the few small boats released by them quickly advanced in front under the paddles of more than a dozen soldiers, and on this sea, they quickly controlled several fishing boats, and then approached the big boat with these fishing boats.

An hour later, Zhao Qi had already seen five or six fishermen in front of him, who had been brought back by several patrol boats, and they were all nervous when they looked at Zhao Qi in front of him.

"Ask them if they are inhabitants of the island ahead." Zhao Qi said.

Wu Min next to him immediately translated Zhao Qi's words.

"Yes...... Yes...... This noble lord, we are the inhabitants of the island. The fishermen immediately spoke.

"Do not be afraid. We're not bad guys, we're merchants, how many inhabitants are there on the island? Which country do you belong to? Zhao Qi asked with a smile, he tried to keep his tone as soft as possible, now that they are in the expansion exploration stage, they naturally want to have a good relationship with the locals.

Wu Min immediately communicated with them, but after these people finished speaking, Wu Min's expression instantly became strange.

Seeing that Wu Min's expression was a little wrong, Zhao Qi immediately asked, "What's wrong?" What's your expression? ”

"It's okay, they just said...... There were only about four or five hundred inhabitants on the island, there was only a small fishing village, and besides, they did not belong to any country, at least they did not know, some of them had fled from Persia, and in any case no one came here to tell them which country it was. ”

"They're mostly self-sufficient, and some of the time they'll go to the mainland to get something." Wu Min said with a strange expression.

"What? Are you sure? You ask again, are they sure that they do not belong to any country? Zhao Qi was a little stunned, but after he reacted, he immediately hurriedly asked.

Wu Min nodded, turned back and began to ask.
