"Large islands?
How big is it?
”When Du Yuhui heard this, he immediately shouted: "It's very big, second young master, I can see it clearly, otherwise how about you come up and take a look in person, second young master?"
”The sentry shouted, "Okay, I'll be here soon!"
”After Du Yuhui finished speaking, he went up to the watchtower, yes, he is still familiar with this place, and later generations have also come by boat, after passing Hainan Island, if you go directly to Jiaozhi, you will not find a big island in the south at all!
He is still wondering, because the most likely place over there is the Xisha Islands, or the Zhongsha Islands, and now his current position, he will not reach the Nansha Islands at all, of course, even if he does, there will be no large islands!
As a result, after Du Yuhui went up to the watchtower, he looked at the south with a telescope and gasped!
Yes, the island that catches your eye is definitely not an archipelago, but a large island!"
Second Young Master, what do you see?"
Seeing Du Yuhui go up, the sunspots are sinking when there are ships!
Then let them come at full speed, and we'll go ahead and have a look!
”Du Yuhui ignored the sunspot and immediately gave an order to the lookout post: Yes, this is an accidental discovery, so Du Yuhui can't wait to find out!"
Second Young Master, is it possible that he has found out?"
After Du Yuhui came down, Shunzi asked: "Well, I can't figure out that there is also a new large island, we haven't had a ship here before, but I don't know if there are people on the island, so we have to mobilize all the manpower, if no one occupies it, it's the best, if someone occupies it, it is inevitable to negotiate with them!"
”Du Yuhui said: Yes, he didn't say it explicitly, there are no large islands in this place in the future, but Du Yuhui is now immune to these conditions, after all, there are not many classics since ancient times that can prove in what era they existed and disappeared in what era, such as Ryukyu Island, etc., and we can also understand that now except for the Great Song Dynasty, the shipbuilding industry of other states is not developed enough, and Zheng He's voyage to the West in later generations is also a matter of hundreds of years later!
So what if the island I saw in front of me finally sank because of the movement of the seabed before Zheng He went to the Western Ocean!
So Du Yuhui's interest in emerging islands now is greater than discovering new things, and ordinary fishermen will not go to the deep sea for fishing operations, this has been said before, you don't have the means to keep it fresh, why do you run so far, if it weren't for Du Yuhui today first trying to find a high sea, and at the same time chasing pirates to the south, plus his own ship lookout distance, this large island more than 150 nautical miles away from Hainan Island, it is estimated that Du Yuhui will not find out!
After all, the situation at sea is complicated, and although there are a lot of sea transportation in recent years, they are all trying to sail close to the continental shelf, right?
And at this distance, even the ships of the Great Song Dynasty will have to sail for a few days to discover this island, so Du Yuhui's first reaction is to go over and have a look immediately!"
Second Young Master, this island is really not small!"
After Du Yuhui and the others rushed over in the first wave, after seeing this island up close, Heizi said: "It's not small!
Tell the ships behind to wait for us when they come, and let's take a half turn first!
”Du Yuhui commanded: "It's the second young master!"
”The sentry went to give the order: Then Du Yuhui and the others began to circle around the island to map and map as before!"
Second Young Master, why is this island so weird!
Half of the vegetation is very dense, and the other half is actually bare, which" Junko looked at the two sides of the completely different islands and said, "Hehehe!
If we don't find anything good, if even the vegetation doesn't grow, then it's an open-pit deposit!
I just don't know what it is, let's go up and have a look!
”Du Yuhui said: "Mineral deposits?
Could it be the iron we got back from the west?
If that's the case, they'll be done!
”Kuroko said: "It's not iron ore, hehehe, but Lao Tzu knows what this is, hahaha!"
We sent it hahaha!
”Du Yuhui said with a smile: "Second Young Master, do you know what these are?"
”When Junko heard this, she immediately asked, "Have you seen that the small ditches in several places on the island are actually frozen!"
”Du Yuhui pointed to the island with a telescope and said, "What does this mean?"
”Heizi asked: "Yes, Second Young Master, we have come all the way, but we have already changed into summer clothes, and although the altitude of this place looks high, it will not freeze!"
Kuroko, don't you feel how poisonous the sun is right now?
But this ice," Junko said, "do you still need to say this?"
Second Young Master, what do you say is going on with this freezing?
”Kuroko asked: "If I'm not guessing wrong, hehehe, on this island in front of me, to be precise, this half of the island is full of open-pit saltpeter mines, this thing can make gunpowder, hehehe!"
There is also one of the most critical uses, especially for our lord's mansion, hahaha!
God help me!
Because this saltpeter mine also has a role, which is to make ice!
Hahahaha!
Free novels bring you joy and joy ---> storyskyline.net
Let's go down and check it out!
”Du Yuhui said with a smile: Then a team followed Du Yuhui to the boat, and then began to land!"
Saltpeter mines?
Can ice be made?
”After getting into the boat, Kuroko asked, "Of course, we used to use the most cumbersome method to store ice cubes to keep the fish fresh, but now!"
If we have saltpeter mines, hehehehe, then we can directly use saltpeter to make ice, so that as long as there is water, then the volume ratio of our sea vessels will be increased too much, when is it needed, when is it necessary to make ice, but there is a problem that needs to be dealt with, damn, if this thing is not done well, it will explode!
That power, but can be compared with the last time we saw the volcanic eruption of tobacco, a ship will be completely destroyed if you are not careful, so when you go to sea in the future, how much ice has been prepared, and a small amount of saltpeter will be carried, if it is not enough, it will be temporarily produced, and if there is an explosion, the whole ship will not be scrapped, and other ships can also respond!
”Du Yuhui said: Yes, Du Yuhui at this time also roughly understood, at present, this island, if it can stay, it would be strange, not to mention anything else, there are so many trees on the island, once it rains and thunders, it causes thunder and fire, hehehe, can this island still exist at that time?
So Du Yuhui's next idea is very simple, once it is confirmed that this is an open-pit saltpeter mine, nothing else will be done, and then a large number of ships will be mobilized to continue mining!
Yes, when he was in the Great Song Dynasty before, he didn't think about finding saltpeter mines, but those are all strategic resources, if the Jue's Mansion intervenes, it will be known by other old guys, hehehe!
I don't know how many twists and turns will fly in front of Zhao Gou's eyes!
Saltpeter mine is indeed important, it is a good thing to produce firearms, but in this year, what Du Yuhui has in his hands can be said to be much more powerful than immature firearms at all, and to produce reliable firearms, Du Yuhui knows that it is necessary to improve the industrial production capacity of the entire Great Song Dynasty, which is not to cross by himself, and then draw some drawings to produce rifles to rule the world, because if the productivity of other industries does not meet the requirements, it is estimated that a single gunpowder can be used as a grenade!
So Du Yuhui will not develop in this direction at all, and at the same time, he also wants to make ice when he gets saltpeter mines, because such a money-making thing makes people impeached and makes Zhao Gou suspicious, which is more than worth the loss, so Du Yuhui has never sent someone to find it, and it turned out that it took no effort to get it today!"
How is the second young master?
Is this what you call saltpeter mines?
”After landing on the island, I didn't meet anyone on the island, or anyone living in the mountains on the other side!
After all, the hair on this island doesn't grow, and the people are not stupid, how uncomfortable it is to live in such a place!
Heizi asked Du Yuhui: "Well, if I'm not bad as expected, this thing should be this!"
Get our water bladders out and I'll test them for you!
”Du Yuhui said: Then Shunzi handed his water bladder to Du Yuhui, after Du Yuhui took it, he got down a piece that looked like a stone, mixed the two, and then an amazing scene appeared, the water poured out of the Shunzi water bladder began to solidify continuously, and finally turned into an ice cube "I rely on the second young master, this is it?"
”Seeing this scene, Kuroko asked in confusion: "It seems that this natural saltpeter mine is even more pure, I thought about purifying it before, but now I don't need anything." ”Du Yuhui said: Yes, he didn't expect that he would accidentally find such a treasure!"
Then what are you waiting for?"
As soon as Kuroko saw it, he immediately pulled out his waist knife and was about to mine and said: "Wait a minute, don't use too much force on this thing, now I don't know if these things will explode when they encounter Mars, so you must pay attention when mining, and then you will get some out, I will get it on the ship and try it with a fire fold to see if it will explode, and we will not be too late to do it after these are all figured out!"
”Du Yuhui immediately stopped Heizi and said, "Second Young Master, I'll let the follow-up ships come over!"
Don't wait on the periphery, when the time comes, everyone will have to contribute!
”Junko said, "Well, give them a signal and let them all come over!"
”Du Yuhui said: Next, Du Yuhui tested whether the ignition can cause the explosion of saltpeter mine, it can be said that Du Yuhui's luck is ridiculously good, this thing can be used directly to make ice, not to mention, there is no one who will not explode, everything is simple after the test, the next three days, including Du Yuhui, in addition to eating, drinking, Lazar and sleeping, is to mine saltpeter mines
