"We all know that activated carbon has the effect of sterilization and deodorization, and can even adsorb formaldehyde molecules in the air, in fact, charcoal also has these effects, but because charcoal molecules are larger than activated carbon, the adsorption effect is not obvious.

"However, charcoal does not have much effect on formaldehyde in the air, but it is more than enough to filter impurities in a seawater. ”

Chen Xu smiled slightly, and took out a piece of black wood from the fire, which he burned with fire and then simmered with sand, compared to those carbonization tools, this is already complete charcoal.

He then found a stone, smashed the charcoal into powder, carefully sprinkled it on the other leg of his shorts, and then clamped the cloth to form a charcoal filter.

"When we carry out secondary filtration, we need to pour the seawater back again, at this time, we must not forget to clean the previous utensils with fresh water, otherwise, it will be white filtration!"

Chen Xu reminded the audience, and then he washed the coconut shell with fresh water, put the shorts with charcoal on it, and filtered it again.

This time, because the coconut shell is very light in color, the contrast with the sea water is even more obvious.

The audience saw that the water was completely clear, almost indistinguishable from fresh water!

"I have to take it, this is too powerful!"

"Xu Ye always has all kinds of wild survival tricks!"

"Fortunately, Xu Ye wore shorts this time, otherwise, it would be interesting to use underwear filtering!"

"Haha, when it comes to underwear, I seem to see Xu Ye's sexy buttocks!"

Chen Xu looked at the barrage, a little crying and laughing.

After straining it, he washed the large stone platform with fresh water and carefully sprinkled the seawater evenly on it.

Compared with concentrated drying in coconut, it will dry faster when sprinkled and the surface area is increased.

Sure enough, the tropical sun was scorching, and before the hare meat was finished, a little white light was already emerging from the stones.

"Almost!"

Chen Xu immediately walked over and saw a layer of white solid crystalline particles forming on it.

Wiped it with his finger, put it in his mouth, sucked it, and excitedly said, "Well, the taste is very close to the edible salt in the supermarket!"

"Congratulations to Xu Ye for getting the seasoning: table salt!"

"Awesome, if you get a little more cumin, you will be invincible!"

"Haha, in the future, Xu Ye's food will be upgraded to a higher level as a whole!"

He was a little excited.

A little salt not only brings the guarantee of survival, but more importantly, it means that his food is no longer simply eating cooked meat, but is beginning to approach the taste of civilized society.

Chen Xu scraped off all these crystals with a stone blade, and got about half a catty, which was enough for him to eat for a long time.

While the hare was not yet fully roasted, he hurriedly sprinkled a little on it first.

After a few minutes, the hare was finally fully roasted.

Chen Xu took it down, blew it, and took a bite of it, "Cool!"

Feeling the taste change in his mouth made his whole tongue jump with joy.

He ate most of a hare, and the rest was wrapped in palm leaves and buried in the sand.

With table salt, Chen Xu actually became more like to eat it than before.

However, he didn't know how many hares there were on the island, so it was better to save some food!

In the afternoon, there was a short rest.

Chen Xu packed up his things and continued to explore the island.

In fact, after two and a half days of searching, he basically knew the environment in the islands below the central level!

The central part is the highest, with many forests in the middle of the island, the second in the east, with reefs and river valleys, with many banyan trees, the lowest in the south, with sandy beaches and jungles, and the western part is medium, with many barren grassy woodlands, and is the area with the highest frequency of rabbits.

The only location I haven't been to is the north.

Because the purpose of this time was to explore, he did not bring a bow and arrows and a water bottle, but only a stone axe, and began to embark on a journey to search the northern part of the island.

Along the way, pass through the center of the island.

"It took me about 30 minutes to walk from the southernmost beach to the center of the island, and it took me an hour to walk from the southernmost beach to the western area. ”

"Based on the average human mountain road of 4 kilometers per hour, the area of this island is about 15 square kilometers, and in the Pacific Ocean, this is already a large uninhabited desert island. ”

I walked for another ten minutes.

He saw the hoof prints again, "It seems that there are indeed wild boars on this island, and there are signs of activity from the west to the north, let's leave it alone for the time being, let's go to the north to see it first!"

To the north, the same cliff, the same as to the east.

Chen Xu squinted his eyes and looked at the sea in front of him, and found a green triangle, and his eyes suddenly lit up, "Look! There seems to be a small island ahead!"

The audience looked through the indented lens of the drone, and wow, it was really a small island!

Moreover, it looks like the area is not small!

"666, is this the rhythm of opening a new map?"

"It's estimated that it's almost, Xu Ye has basically visited this island"

"Wocao, discover a new continent!"

"Niijima should have more resources, right?"

Chen Xu saw the barrage and nodded:

"You're right, it's good news, because more desert islands means more resources and opportunities, and it means hope for survival, but I don't have the strength to get there yet, because the sea level is flatter than the land, so I see the distance farther than the land. ”

"According to my estimates, this distance is at least more than 7 nautical miles, that is, more than 12 kilometers, and it takes about 10-13 minutes for a human to swim one kilometer, which means that it takes me 4 hours to go back and forth, and even top swimmers can't swim for so long!"

"However, I can make a boat as a means of transportation, but it is not easy to make a boat that sails back and forth on the ocean for four hours, because this is the largest Pacific region in the world, with rough waves and sharks!"

"We still have to plan carefully before we can act!"

After speaking, just as Chen Xu was about to leave, he suddenly found that at the bottom of the cliff, there was a white object floating on the shore.

"Look, there's something hanging from the reef down there!"

He lowered his head and looked closely, "It's like a canvas! It's a good thing, a canvas from the civilized world, and it can do so much: sheets, rain covers, clothes, even sails!"

"You know, a boat that can sail for four hours in the Pacific Ocean is difficult to compete with the waves without the help of the sea breeze, and I must get this canvas!"
