He reached into his pocket and saw that it was a small magnet, so he asked him to stop and bring the iron close to it, and the magnet snapped up.

"Iron here?" Wang Yang was slightly surprised, but he didn't think much about it, iron ore is widely distributed on the earth, and there are many of them, and this planet is no exception, there are traces of iron ore found in many places, but it is different from big to small.

The big grizzly bear hadn't found the food yet, so he hugged the little white bear tightly and screamed angrily.

It returned along the way, did not continue its exploration, and returned to Tunnel 2, where Wang Yang had stored his supplies.

When it got here, it sat on the ground, licked the bear's paws by itself, and licked the little white bear, Wang Yang was very puzzled, they seemed to like to do this action very much, and they didn't know what it meant.

Then, the big grizzly bear looked at Wang Yang, and from time to time he looked at Wang Yang's palm, his eyes were gloomy.

Wang Yang was looked at it strangely for a while, and quickly looked at his palm, he didn't think there was anything wrong, hair or something, he had just shaved, white and white, very clean.

Could it be that you are thinking about why you don't lick your palms? So what about licking yourself? Or not licking?

Wang Yang's hands are a lot rougher, even if it is a relatively tender palm, of course, it is only more tender, because there are more muscles in the thumb.

The palms of the hands are covered with thick calluses, most of which are related to wooden objects, and many of them are taken out with wooden spears.

Looking at such a hand, Wang Yang still felt that he didn't lick it anymore.

When I looked up again, I saw the big grizzly bear drooling, and the guy who dared to love was not thinking about why he didn't lick his palm, but wanted to eat people's palms!

Wang Yang knocked the wooden spear very unhappily, and the big grizzly bear hugged the little white bear. Put it to your mouth and wipe it off, good guy. It was directly used as a handkerchief.

But Wang Yang always felt that there was another deep meaning, and it was estimated that the big grizzly bear felt that the little white bear was not too careful. Wiping your saliva on it will make the bear more familiar with its own scent and stimulate the bear's ability to distinguish between relatives and enemies.

However, it seems that it has failed to educate the little white bear, and the little white bear has not yet learned the ability to distinguish danger, and even if it does, it is estimated that it will not regard Wang Yang and others as enemies.

This way seems to have had a certain effect, and it didn't take long. The little white bear wanted to come to Wang Yang again to ask for food.

But this time, when it came to the river, it sniffed the air with its nose, and indeed distinguished that the smell of the big grizzly bear was different from that of the group of people opposite.

It hesitated, looked at the water, looked at Wang Yang and the others, and then looked at the big grizzly bear, thinking about whether it should go? Or not?

How sad can you be, just like a river of spring water flowing eastward, it is estimated that it is the mood of the little white bear at the moment.

Wang Yang naturally knew. It's not that the big grizzly bear's method is magical, but the big grizzly wanted to attack him before, but he fought back.

The little white bear was frightened and frightened, and couldn't figure out why the two sides were fighting. Which side should you be on.

So Wang Yang didn't say a word, but took out a piece of dried meat.

As soon as this meat came out, the big and small bears were all drooling. The little white bear was even more spineless and happily went down the river and swam to the other side. Straight to Wang Yang.

Wang Yang was not happy, but ran back. When the little white bear saw Wang Yang running away, he also jumped up his fat four calves and chased after him.

The grizzly bear faced another failure to teach his son, and stood there in a daze, as if he had lost his heart and didn't want to chase anymore.

Wang Yang just ran forward, on the other side of the river dripping around in a circle, away from the little white bear, he slowed down, the little white bear looked like it was about to catch up, he jumped, let the little white bear pounce in the air, continue to run.

The little white bear chased happily, and finally caught up with Wang Yang, put the food in his mouth, didn't eat, and ran to the side, looking back to see that Wang Yang didn't chase it, he ran back, and when Wang Yang stood up, it ran forward, as a game.

Wang Yang smiled, caught up with it all of a sudden, and threw it down, the little white bear hugged Wang Yang's neck very excitedly, and then began to eat the food in his mouth.

The little white bear still wanted to play, but Wang Yang was not in the mood to play with it, but Wang Yingying found it interesting and chased after it.

And Wang Yang came to the other side and called with a smile: "Let's go and see the place just now." ”

Then he said to Xiaohong and the others: "You just stay here, and Xiaoxiao and I will go back as soon as we go." ”

Xiaohong glanced at the big grizzly bear, and was a little worried: "If you don't call the blade-toothed tiger too?" There are too few of you, and if a grizzly bear follows you, you won't be able to defend against it. ”

Wang Yang thought for a while and nodded: "Then you two will go and stay on the big rock, it will be safer there." ”

"Hmph, how could it be, isn't it just a bear?" Xiaohong is very confident.

"It's not too difficult to hunt a bear, but I don't want you to kill a bear, I want you to defend against a bear, how do you know when a bear will attack you? It's close to you, can you kill it? And expect it to know the way out. If you don't kill it, as soon as it gets closer, it will be violent against you, what is the use of an ordinary bronze sword? ”

Wang Yang reprimanded her very harshly, to underestimate the enemy is to kill himself, the big grizzly bear is hungry and anxious, it is very possible to attack people, the difference between wild beasts and ordinary animals lies in their wild characters, wild and untamable.

What's more, you haven't tamed it yet, so Wang Yang watched Xiaohong and Wang Yingying get on the big stone, and then beckoned to Xiaoxiao.

The two of them got into a boat with the Bladetooth and traveled through a dark tunnel, lit with small torches.

"How many things do we have to burn besides clothes?" Wang Yang asked.

"There's not much left, save some of it, and you should be able to last until the food is finished." smiled and replied.

There was no communication along the way, and at the end of the tunnel, Wang Yang approached the place where he had attracted his magnet.

It was a smooth stone that was not peculiar, and it looked a little crystal clear, like glass, and a little like crystal.

It was this substance that made Wang Yang's magnet have a reaction of attracting, Wang Yang took out the magnet and leaned forward again.

It was adsorbed again.

"What kind of iron ore is this? How is this color? "Meteorite iron ore Wang Yang has seen a lot, most of the potholes are uneven, like a year full of pimples.

And most importantly, the color is dark, or there is red rust on the surface, which is the general form of iron, how can you see a piece of "iron" with high transparency?

Wang Yang took the magnet down, took out the copper hammer, and struck at the translucent stone with the square surface.

Syllable! It was so crisp that it was so crisp that it was speechless, revealing a little yellowish irregular particles inside.

"What the hell is this...... Gold? Wang Yang's eyes immediately turned into ¥¥, but he quickly shook his head, what are you doing with gold these days, I really want to have it, I have already sent someone to mine it, and I haven't found it.

But in general, gold has little effect on development, it is only an alloy material, and it is more used as a symbol of wealth.

Wang Yang understands this quite well, so he is not surprised at all, and he is not happy because of the discovery of yellow substance.

Maybe it's not gold? What's more, no matter how stupid Wang Yang is, he knows that gold will not attract magnets.

The torches were brought to the front, and the tunnel wind was howling, and the ghosts were crying wolves, which was not very pleasant to hear.

The light of the fire was blown and swayed, sweeping over the yellow granular unknown object from time to time, and suddenly, a blue glow suddenly ignited on the yellow particles.

Then, as if infected, the small hole quickly burned into a blue light, and thick smoke poured out.

Xiaoxiao was startled, she felt very strange, she thought it was a low-temperature phosphorus fire, and she actually reached out to touch it.

Wang Yang suddenly remembered something, knocked her hand off, and then picked up the water and extinguished the blue ghostly fire.

Before Xiaoxiao could ask what was going on, Wang Yang hurriedly took out two handkerchiefs, dipped his hands, one covered his nose and the other covered Xiaoxiao's nose, and fled in a hurry.

Xiaoxiao was inexplicable, but seeing Wang Yang's solemn expression, he obediently followed the rowing boat and rowed out of the tunnel, only then did he see Wang Yang loosen his handkerchief and exhale deeply.

"What's going on? So what is Blue Fire? Phosphorus fire? Xiaoxiao didn't say ghost fire, ghosts have not yet been formed.

"No, not phosphorus fire, but carbon dioxide with poisonous gas." Wang raised his eyebrows and frowned slightly.

"What? What are those yellow particles? Xiaoxiao didn't understand it even more, she had also read the chemistry written by Wang Yang, and knew that many chemicals could burn blue flames.

But what the hell is this, this is not at all an empty and boring chemistry book can explain, or rather, Xiaoxiao is not a genius, chemistry is difficult for her.

"Those things, it's brimstone." Wang Yang exhaled, picked up the small translucent fragment, and looked at it carefully in the firelight.

"Brimstone?" Xiaoxiao was stunned for a while, and after thinking about it for a long time, he didn't figure out what the sulfur explained in the chemistry book was.

"How did you forget? I've taught you that sulfur is flammable, and then extracts its substances, which can be used for many purposes, and I told you a joke about a man who drank water and died foaming at the mouth. ”

As a chemical, sulfur has many functions, it can be used to process chemical fertilizers, it can also be used to make poison, it can also be made into explosives, some sulfur contains arsenic, arsenic is what everyone knows, in ancient TV dramas, it is always said that arsenic is given to people, poisoning people.

"Oh, that's what you're talking about...... So should we mine or not? Doesn't seem to be useful, right? "I smiled and asked myself, I don't know how useful it is.

"Let's pick some and use it, after all, this is natural sulfur, and the proportion of sulfur is relatively high, go back to refine and refine, maybe it can be used."

So Wang Yang took out the map and immediately made a mark on the location.

When they came to the three-way intersection of Tunnel No. 2, the Blade-toothed Tiger suddenly roared, and Wang Yang and the others immediately became cautious, with solemn faces.

There was a strange murmur between the caves, "Whoa~Quack~Haha~" All kinds of strange sounds kept coming from the side of Tunnel No. 1, making the pupils of the two people at the intersection of Tunnel No. 2 constrict, and they didn't understand what was going on. (To be continued......)
