Chapter 1018 The Advantages and Disadvantages of Volcanoes (Part 2)
Zhou Xu had to admit that he knew little about volcanoes.
Although he is a modern man, he is not a network confrontation master like Wang Pengfei, who checks everything in order to confront others.
Who would have the time to study this? He basically only knows about things that interest him, and volcanoes are obviously not within his scope of interest.
After Zhang Xuemei said this, Zhou Xu's thoughts obviously changed.
If the loss that the volcanic eruption might bring him could be compared to the number fifty, then he only needed to create a value of one hundred or even two hundred with this piece of land.
In this way, even if the volcano erupted, from the perspective of the value of the benefits obtained, he suffered a loss of 50%, but still had a profit of 50, or even 150. He still made a profit, which can be said to be more beneficial than harmful.
Zhou Xu has always been a decisive person. Even if he is entangled, he will not hesitate for too long.
Now, after listening to Zhang Xuemei's words and figuring out the benefits that volcanoes can bring to him, his mind suddenly opened up.
[Volcanic ash can make the soil fertile, making the land here suitable for farming, which is just right. ]
[This is an island after all. If we always need to transport food from the mainland, it will be a hassle even without considering the transportation costs. Building a farm and reclaiming farmland directly on the island is undoubtedly the simplest way, and it will also be beneficial to the future development of this island.]
[And about geothermal energy, Qin Fen should know about it, right? I'll ask him later.]
Just as Zhang Xuemei said before, a dormant volcano like this may not erupt for hundreds of years.
Although the potential risks cannot be ignored, sometimes being too entangled and hesitant will undoubtedly affect development.
Just imagine that over hundreds of years, the value that this land has produced for you would probably have long exceeded the losses caused by the volcanic eruption.
As his thoughts raced, Zhou Xu's gaze fell on Zhang Xuemei again.
"You just mentioned sulfur. Is it one of the main materials for making gunpowder?"
As one of the four great inventions of China, Zhou Xu had a little understanding of gunpowder.
Zhang Xuemei listened and nodded directly.
"Yes, the main materials of early gunpowder were sulfur, potassium nitrate and charcoal."
There was no need for Zhou Xu to ask further questions afterwards, as Zhang Xuemei continued talking on her own.
"Charcoal is nothing special. As for potassium nitrate, it's relatively easy to get. You should be able to find it in the toilet."
“…”
Obviously, this answer was a little beyond Zhou Xu's expectations, and he even suspected for a moment whether Zhang Xuemei was joking with him.
Besides looking for shit in the toilet, can you also find potassium nitrate?
Zhang Xuemei probably sensed Zhou Xu's confusion, so she explained.
"After chemical reactions, the organic matter in human urine will produce potassium nitrate or nitrate."
Having said this, Zhang Xuemei paused.
"If we want to develop gunpowder, even though we haven't found sulfur yet, we can collect potassium nitrate first."
Zhou Xu listened and nodded.
"I will give instructions on this matter later."
Although the fact that the resource output point was in the toilet made him feel a little complicated.
But when he thought that he didn't need to collect these things himself, he felt fine.
This trip took him a lot of time, so Zhou Xu naturally didn't plan to stay here for a few days and then leave.
This time he came here in person, on the one hand to meet the time traveler Tanaka Yotaro, and on the other hand he planned to use his "Eyes of Secrets" to conduct a comprehensive exploration of the island.
This will also make it easier for him to plan the subsequent development of the island.
At this stage, judging from the size of this island, Zhou Xu feels that he probably won’t be able to go back this year.
He had just finished a long journey, so he was not in a hurry and planned to rest for two days first.
In comparison, Zhang Xuemei started her work here directly after a night's rest.
The first thing to do is to go to the volcano and make a thorough confirmation.
It is actually not difficult for them to go to the volcano. They can just take a hot air balloon.
Tanaka Yotaro had already built a hot air balloon before, but at that time his mind was full of returning to the mainland and taking back the capital, so he probably didn't think about this matter at all.
Compared with the crude hot air balloons produced here, the hot air balloon manufacturing technology in Da Zhou is undoubtedly much more advanced, and the overall quality is obviously better.
The hot air balloon took off quickly, and during the period, the two hot air balloon operators also skillfully performed mantras to bless the hot air balloon so that it could fly faster and more steadily in the air.
Their Da Zhou hot air balloon has a very high mobility efficiency.
As we all know, the speed of a hot air balloon depends largely on the wind. Simply put, the stronger the wind, the faster the hot air balloon moves.
In high-altitude areas, the higher the altitude, the stronger the crosswind.
From this point of view, as long as it is raised to a sufficient height, the speed of the hot air balloon can increase rapidly.
However, the risks will also increase significantly.
But the standard mantra of the hot air balloon operators of the Great Zhou Dynasty is to enable the hot air balloon to fly stably and at high speed in such dangerous strong winds. This is the secret of their high mobility efficiency.
Ordinary hot air balloon operators would not dare to do this. Only those who possess the true words would dare to do this.
This was not the first time Zhang Xuemei had ridden in a hot air balloon, so she was quite calm at the moment.
Maintaining their high-speed flight, they soon arrived above the mountain.
"No, we can't get any closer!"
The experienced hot air balloon operators soon noticed that the air flow in the area was wrong, and they could also feel an obvious heat wave, which forced them to quickly control the hot air balloon to keep their distance.
During this process, Zhang Xuemei, who was almost half out of the basket, had already activated the "Eye of Insight". After a brief close observation, she was basically certain that this was a dormant volcano!
However, Zhang Xuemei obviously had no intention of going back home just like that.
This time, she had other work to do besides making a final confirmation of the volcano when she came out on a hot air balloon ride.
In fact, confirming the volcano was just a by-product.
Now, with the help of the "Eye of Insight" and the high-altitude vision provided by the hot air balloon, Zhang Xuemei also quickly swept through the area.
Meanwhile, in the island village...
Zhou Xu said he was going to take a rest, but he didn't intend to just sit there doing nothing.
After all, he is essentially a person who can't sit still.
On a new day, after a good sleep, Zhou Xu asked Bai Tu to find a relatively spacious open space for him.
Needless to say, he was planning to conduct a round of mantra testing to try out what kind of effect the two new mantra characters he obtained yesterday could produce after combining them with the mantras he already had.
