It took more than an hour to walk inside, because no one had ever lived on this island, so there was no road, resulting in a very slow walk, and it was almost 1,000 meters or so for more than an hour, Cheng Ran estimated.

However, there are also two good news along the way, traces of animals were found, Cheng Ran looked at these footprints should not be caused by small animals, Cheng Ran felt that there was a great possibility that they were caused by large animals such as wild boars, and a person found a hill.

The two of them followed these footprints to find a waterhole, saying that it was a waterhole but it was too shallow, Cheng Ran picked up a relatively thick wooden stick, walked to a relatively low-lying place and began to dig up, and dug a pit nearly thirty centimeters deep in less than twenty minutes, but the water is very turbid, and the turbidity should be precipitated by impurities, far away from the pollution of cities and factories, this water source should also be clean, Cheng Ran is happy now, I feel that I will not worry about the problem of water source during this time, It's just that the shelter is far away, and there is nothing to hold water, so it seems that we can only find a way to see if we can find something suitable to hold water.

After finding the water source, the two began to walk back, and did not continue to explore further, after all, there was still a major matter that had not been solved.

By the time the visitor returned to the shelter, it was already nearly an hour later, and there was no other exploration on the way back, and it was also along the road they had traveled before, but fortunately, neither of them went in the wrong direction this time, and it only took half the time to return to the shelter.

Cheng Ran felt that if there was a lighter to make a fire at this time, it would be a matter of one second, even if he almost gave him a flint, it would be three or four seconds, but it was a pity that Cheng Ran didn't even have a knife except for a pair of hands.

To put it bluntly, it is very simple to use friction to generate heat, and then ignite some flammable items when enough heat is generated.

At this time, Li Yuxin walked to the beach to see if she could pick up some small crabs or the like.

At this time, Cheng Ran suddenly remembered that when he was a child, he had seen a carpenter use something similar to a bow to drill wood.

Cheng Ran decided to make a bow first, then wrap the wooden stick used to make a fire around the bowstring, pull the bowstring back and forth to drive the wooden stick to rotate, and then rub the wood to generate heat to achieve the purpose of making a fire.

Cheng Ran felt that he could also try to at least his hands would not be uncomfortable again and he couldn't hold things, so he thought about it while looking for a suitable wooden stick to use as a bow, and after wandering around for a while, he found a curved branch to use as a bow, and it didn't need to look good, it just needed to play a fixed role, and it didn't need to be strong, as long as there was space in the middle of the bowstring for the wooden stick to pass through.

As for the bowstring, Cheng Ran felt that it was okay to try it with rattan first, but he was thinking of other ways, but the bowstring broke after a few strokes.

Cheng Ran scratched his head and looked depressedly at the things needed to make a fire on the ground, thinking that it might be because of the quality of the bowstring that directly determines whether this fire can be successful, and then saw the pair of shoes on his feet, and felt that he could try it with a shoe belt, this is an industrial product, it must be much better than emphasizing these rattans or something.

In order to use the bow a few more times, Cheng Ran grinded a groove with stones at both ends of the bow, and then tied it at both ends with shoelaces, a simple bow was done, and the bowstring was tied relatively tightly, and the bundle was loose for fear of not being able to bring the fire stick, so he wound the fire stick around the bowstring, and then put the wood made in advance on the top of the fire stick, and of course, he also carved a circular groove with stone in advance, in order to prevent the fire stick from running around and controlling it.

The left hand pressed the top of the fire stick with a wooden block, and the right hand pulled the bow back and forth, in less than a minute, a very obvious smoke was emitted from the contact between the fire stick and the wood, and after pulling back and forth a few times, Cheng Ran stopped, because he saw a little coconut velvet lit, and then immediately wrapped it with some coconut velvet, and gently blew it with his mouth on the faint spark, and soon, the smoke became bigger and bigger, and then he gently shook the flame twice and burst out, and then quickly put it on the ground, He put the dried leaves and branches on top of it one by one, and after a while the fire grew bigger and bigger.

The fire finally lit up, Cheng Ran threw the larger wooden sticks he picked up before into the fire, looking at the bigger and bigger fire, Cheng Ran was very happy, feeling that there were no flowers in vain in the past few hours, and having a fire means that what can be eaten can also be improved, and it doesn't have to be so cold to sleep at night.

Cheng Ran went to find a lot of large stones, built a circular fire pit in front of the shelter, left a gap at the door of the shelter, and moved the fire inside, so that it could prevent the wind and save some firewood, saying that there is no need to worry about firewood on this island, but it will take time to find it, so that it can save some time to do other things, and get some materials for the fire and put it in the shelter, because no one knows when the fire will be extinguished, and when it will rain, When I look for these things at that time, I really can't find them.

At this time, Li Yuxin came back and walked to the door with a banana leaf, and Cheng Ran saw that there were a lot of things that looked like shells.

"I only found these, I don't know if they can be eaten, I found some small fish and crabs but didn't catch them, and there are two pieces of dong that look like salt." Li Yuxin said with some embarrassment

"Yes, it's nice to have these, I'm sorry for you." Cheng Ran said happily

At this time, the two sat in front of the fire, and Cheng Ran put those shells on the stone to roast, and had no kitchen utensils so they could only roast and eat on the fire.

"If only there was a pot, even if there was a clay pot, it would be nice to be able to cook and eat." Cheng Ran looked at the fire and said

"Now that it's on fire, we can try to make some." Li Yuxin looked at Cheng Ran and said

This shell has been tested, Cheng Ran took one and handed it to Li Yuxin and said, "Then let's go to the water source tomorrow and try to make some, after all, it is also urgently needed now, and a container is needed to hold water." ”

"Then you can help me cut some rattan tomorrow." Li Yuxin said while eating

Cheng Ran held the shell in his hand and said differently, "Why do you want rattan, you can't use it now." ”

"I want to make a mat and a basket for shells and fruits, it's too inconvenient to hold them every time, and it would be nice if I could make a fish catcher, so it would be good to have an extra source of food." Li Yuxin said

"Okay, I'll chop more rattan tomorrow morning, and you'll weave something?"

"I used to learn to play when I was bored, but I didn't expect it to come in handy now."

After eating, the two threw a lot of firewood into the fire and walked into the shelter, because the wind was too strong in the middle of the night last night, they both lay down back to back by the fire at the door of the shelter.
