Desert Island Survival Belt System

Chapter 342 370

There was a gentle breeze, and the interior of the island was also hot and dry. The midday sun was emitting high temperatures from burning air.

"Whoosh..."

There was a refreshing wind blowing from the entrance of the canyon, and a shrub standing at the entrance of the canyon was swaying back and forth.

A big turquoise praying mantis is gnawing its prey with its mouth. Among the meat-eating insects, the mantis is undoubtedly the best at the top of the food chain.

However, the eating of the praying mantis was interrupted, and several huge figures approached from far to near. The big green mantis had no choice but to hide immediately. It jumped and fell towards the bushes.

However, the place where it fell was not the ground or the grass, but a huge spider web. The mantis was stuck by the spider web. When it was struggling, a bloated spider with a big belly crawled over, and then the mantis turned into a white cocoon .

"That's right here!" Qin Fengyi passed by the bushes, and he didn't notice the brutal fighting in the bushes. The law of survival of the jungle is the survival law of nature, and it happens every moment.

"Isn't this the place that... Saron... Ke... Si brought us here?" It was hard for Lin Qingxue to remember such a complicated name.

Yes!

This narrow canyon was indeed brought by Saronkos, and the two of them still died here. Not far from the entrance of the canyon, their bodies eaten by murlocs are still here.

The reason why Qin Fengyi chose this place is firstly because it can walk back along the canyon, and secondly because there is a treasure that he has been looking for for a long time here.

"That's right, this canyon can lead all the way to our shelter, which is the gold mine!" Qin Fengyi pointed to a wall, "And there are very valuable things here!"

"Stone?" Han Xuening didn't understand. The stones on both sides of the canyon looked rough and simple, and they didn't look like treasures!

Lin Qingxue seemed to have discovered something. He had a simple confrontation with the murlocs in the canyon just now. The crossbow arrows on Saturday and Sunday had once hit the stone wall. At that time, the crossbow arrows hit the wall, and the metal arrows rubbed against the wall. Now there are still bursts of smell coming out. .

"This..." Lin Qingxue searched for the smell, and found a piece of stone on the ground. The little girl looked at this white and clean stone in shock. It was a bit like glass ceramics.

Generally speaking, it should be similar to the combination of glass and ceramics, with the smoothness and transparency of glass, while the stone flakes look translucent, pale white in color, and smooth to the touch.

"This can't be... saltpeter, right?" Lin Qingxue looked shocked, and then looked towards the stone wall. As far as she could see, the stone walls on both sides of the canyon were covered with this kind of shiny and translucent stuff. Glittering in the sun.

"Oh my God, these are all saltpeter!!" Han Xuening was also shocked. You must know that Qin Fengyi was crazy looking for saltpeter, but he couldn't find it all the time, and now he finally found it.

"That's right, saltpeter can be used to make gunpowder!" Qin Fengyi said confidently, "Now that I have found saltpeter, I can make charcoal by myself. If you want sulfur, you can try your luck in the depths of the swamp."

There should be a crater deep in the swamp. The last earthquake and tsunami caused a slight change in the texture of the deserted island. The changes in the crust are so weird.

There are reasons for thinking that there is a crater in the swamp. The first reason is because Qin Fengyi smelled a sour smell when passing by the swamp when he was transferring from the ancient city.

The smell of sulfur is no stranger to the people in Qin Fengyi Village, because there is a sulfur plant on the mountainside in the village, and whenever the south wind blows, the whole village smells of sulfur.

This memory imprinted in my bones, and I smelled that familiar smell again when I was breathing in the swamp, it was undoubtedly sulfur.

Moreover, the behavior of the crocodiles in the swamp is very strange. They all left the deep downstream of the water area and gathered in the upstream. You must know that the downstream fishery is very rich and the food is abundant. They must gather for some reason without much food. upstream.

As for the reason why the crocodile left the lower reaches of the swamp, it was all because the volcano would release a poisonous gas, which was so heavy that it would sink to a depth of 1.5 meters. Although the crocodile was very long, its overall height was less than half a meter.

Wanting to go to the depths of the swamp, Qin Fengyi thought about building a raft before. Sitting on the raft, he can go down the river and quickly reach the depths of the swamp. Not only can he avoid crocodiles, but Qin Fengyi's overall height can also avoid the sediment in the swamp. Toxic gas below 1.5 meters.

However, plans are nothing compared to changes. Now that Qin Fengyi has obtained the magic source of druids, he can transform like a real prehistoric druid. He can grow a pair of wings anytime and anywhere, and fly freely in the sky.

Closer to home!
Several people are discussing the function of saltpeter. Saltpeter was discovered and used by people as early as ancient times. Among them, gunpowder, one of the four ancient inventions, is one of the four great inventions of ancient times!
After saltpeter is developed into powder, it can be mixed with many things to make strong gunpowder. Unfortunately, this magical thing was known to foreigners. In the following hundreds of years, they made arquebus guns, combined with gunpowder Come to invade China.

It is said that when you drink water, you think about its source. Maybe the descendants of foreigners don’t know that gunpowder is what their ancestors came to China to obtain. Maybe the origin of gunpowder is not written in the records of foreigners at all.

"Saltpeter can be used as gunpowder..." Lin Qingxue held the glass-like stone in her hand and shook her head slightly, "This shell can not only be used as gunpowder, but can also produce a chemical reaction with water."

"That's right!" Han Xuening also nodded. The beautiful teacher and Lin Qingxue are both top students, and Qin Fengyi is a typical scumbag. He doesn't know anything about chemistry. The water becomes cloudy.

"Ah..." Qin Fengyi didn't know what mixing water and saltpeter could do, so he could only nod like this, in order not to embarrass himself too much.

"You, what does "ah" mean?" Lin Qingxue had a rare chance to hit Qin Fengyi, the little girl walked over slowly, and patted his shoulder with her small hand, "Do you really know that saltpeter mixed with water will become something?"

"If I say I don't know, can you laugh at me?" Qin Fengyi's advantage is that he has a thick skin and is very honest.

"Haha, actually, when saltpeter is mixed with water, a very miraculous chemical reaction can occur. As early as our ancient times, the ancients discovered this phenomenon." Lin Qingxue continued to play tricks.

"Say it quickly..." Qin Fengyi urged.

"Because, after water combines with saltpeter, it will become..."
