"It's strange that this island has freshwater lakes but no plants." 'Jack Twain' said on the side.

"Well, let's take a look!"

Ye Xiuwen said, and continued to walk towards the island with 'Jack Twain'.

This island is very strange, not only is there no grass to say, but the mountains are all bare stones.

There is no dirt on the road, or there is very little dirt.

But even if there is a small amount of soil, there should be weeds to survive.

But maybe the island is too far inland for grass seeds to float here.

In other words, it is very likely that the island was not very old.

Ye Xiuwen could only guess like this, but he didn't want 'Jack Twain' to say at this time: "Mr. Black Wolf? Don't you think it's strange? They say that many people have died on this island, but we have not seen the bodies of those people until now. ”

"Are you interested in corpses?" Ye Xiuwen asked rhetorically.

"No, no, I just think it's weird." 'Jack Twain' shook his head.

"Okay, then let's find the truth. I don't know where Hydra is now, and I don't say anything to greet it. Ye Xiuwen looked left and right, but he couldn't see any traces of human activity at all. Or maybe the people of Hydra, who have never survived here, after all, the island is really big.

"Mr. Black Wolf? Shall we shout twice? "'Jack Twain' suddenly suggested.

"I think it would be better if we weren't discovered. Otherwise, what if they come and say they want to replace you? Ye Xiuwen looked at 'Jack Twain', and 'Jack Twain' pouted, knowing that he had said the wrong thing.

At this time, Ye Xiuwen actually had another strange electronic instrument in his hand.

'Jack Twain' said strangely, "Mr. Black Wolf? What is it? ”

"Air quality detectors, which used to be used to monitor smog. Later, it was improved by our wolf warrior to monitor toxic gases. Now the air quality is okay. Nothing. ”

Ye Xiuwen picked up the instrument again as he spoke, but at this time, 'Jack Twain' was very admiring and said: "Huaxia is really powerful, such a small box can monitor the air." Our air detector should be so big, like a small suitcase. ”

'Jack Twain' said as he gestured. But Ye Xiuwen smiled: "Actually, this is like a problem where one plus one equals two."

Many people know that one plus one equals two. But when asked suddenly, I don't know how to answer, and I think of a variety of possibilities.

So, it's not good that this person is too smart, and people who often don't seem so smart go the nearest way. ”

"Hehe, Mr. Black Wolf, I see, you mean that many Westerners nowadays think they are smarter than Easterners. They keep their skills hidden. But I don't want Huaxia to catch up unconsciously. And is it the easiest way to use it? 'Jack Twain' asked.

"Clever, that's it." Ye Xiuwen smiled, and then asked 'Jack Twain': "Do you know when human beings will share technology?" ”

"It can't be, right? Even different companies in the same country wouldn't do that, would they? 'Jack Twain' asked rhetorically.

"Yes, people have always been in a competitive relationship, and one group and another group are also competitive relationships. One country and another country are also in a competitive relationship.

In such competition, all countries or individuals begin to be wary of each other, and even hate each other,"

"But in this way, people can't understand each other, can't they?" 'Jack Twain' suddenly interrupted Ye Xiuwen's words.

"Yes, one day humanity will open up this barrier and become one." Ye Xiuwen said with great certainty.

"When?" 'Jack Twain' asked.

"When another powerful enemy appears."

Ye Xiuwen smiled, and then continued: "Whether it is an individual, a collective, or a country. When faced with an enemy, or several enemies, they can always let go of their previous suspicions and come together,"

"That's too hard, isn't it?" 'Jack Twain' interrupted Ye Xiuwen again.

"Well, it's very difficult, so let's look at the present, you see!"

Ye Xiuwen pointed out that he had already walked a long way while chatting with 'Jack Twain'.

At this time, Ye Xiuwen and 'Jack Twain' walked in front of a small lake.

It was a pool of green water.

The water is calm, there is nothing, no seabirds, no fish in sight. And 'Jack Twain' just wanted to pick up the water and taste it, but was stopped by Ye Xiuwen.

"Mr. Black Wolf?" 'Jack Twain' looked at Ye Xiuwen in surprise.

"I finally know why there are no plants or animals living on this island, what do you think this is?"

Ye Xiuwen said, wiping the yellow stone-like thing next to the pool with his hand.

His hands were stained with yellow powder.

"What is this?" 'Jack Twain' said incomprehensibly.

At this time, Ye Xiuwen sniffed, and then said: "It's sulfur, sulfur is a kind of lumpy light yellow crystal, the powder is light yellow powder, it has a special smell, it can be soluble in carbon disulfide, insoluble in water."

The chemical properties are relatively active, and it can be combined with most elements such as oxygen, hydrogen, halogens (except iodine), metals, etc., to form ionic compounds or covalent compounds.

Sulfur elemental is both oxidizing and reducing.

For example, sulfur is coheated with iron to form ferrous sulfide, carbon disulfide is formed with carbon at high temperature, sulfur hexafluoride is formed by fluorine at room temperature, S2Cl2 is formed by chlorination when heated, and so on, etc., etc.

"Oh, I remember, sulfur is in industry, it can be used to make sulfuric acid, vulcanized rubber, black powder, matches, sulfides, etc., and in agriculture, it can also be used as a pesticide, am I right? Mr. Black Wolf? "'Jack Twain' first suddenly realized, and then confirmed to Ye Xiuwen.

"Yes, you're right. But what you don't know is that sulfur burns in the air, and when it burns, a blue flame occurs, producing sulfur dioxide, which is poisonous, so on this island, not only animals can't survive, but even plants can't survive.

Some scientists have even proposed that the dinosaurs became extinct because of sulfur dioxide. ”

Ye Xiuwen spread his hands and explained, while 'Jack Twain' nodded frequently. But it didn't take long for him to wonder again, "Where did all this sulfur come from?" ”

"Volcanic eruptions produce large amounts of sulfides. These sulfides react chemically at high temperatures and eventually turn into sulfur and settle here.

It has become a natural sulphur mine, which is spectacular, and I am afraid that there is no problem in mining millions of tons of sulphur here. ”

Ye Xiuwen slightly admired the miraculous work of nature, which can always find a way to transport the minerals needed by human beings from dozens of kilometers, or even hundreds of kilometers underground, to the ground.

Moreover, who can imagine what is buried in the ground for tens of kilometers, or hundreds of kilometers! Please Baidu "Throw Book Network" Thank you for your support!
