Cheng Ran walked around the jungle for a while before coming out of the jungle, and when he came out, it was already completely dark.

After walking to the shelter and cooking some conch and shell things to feed Li Yuxin, he ate something casually and fell asleep.

When he got up the next morning, Cheng Ran walked to the beach and started a daily sea mission, Li Yuxin used to come over, and now Li Yuxin fell ill and fell on Cheng Ran, Cheng Ran walked along the seaside to the west, today is a little more skilled than yesterday's technology, and naturally there is a little more than yesterday's harvest, when he walked around a corner, Cheng Ran saw something floating on the sea from a distance, and immediately ran towards that side.

When Cheng Ran got closer, he thought suspiciously: Is it kelp at this time? Put down what you were holding and swim towards the kelp-like side.

When Cheng Ran swam over there, he could be very sure that this was kelp.

At this small corner, the water is full of kelp wafting in the wind, each one very large, about 20 centimeters.

Cheng Ran immediately dragged a piece and swam towards the shore, thinking: The kelp soup that can be drunk today, after the kelp is dried, as long as the moisture-proof is done, it can be stored for a long time, and the kelp also contains iodine that is necessary for people, if people lack iodine for a long time, they will have no spirit and weakness in their limbs.

When Cheng Ran was dragging the kelp, he also found that there were fish in it, all of which were big fish more than one meter long, and he couldn't hold it at all when he tried to catch it, so he could only make a fish cage to catch it.

Cheng Ran began to walk back and forth, thinking as he went: I can try to see if I can make some mud bricks, and if I can make them, I can try to burn other things.

After arriving at the shelter, he started a day's breakfast, first boiled a pot of kelp soup for Li Yuxin to feed half of it, and drank half of it himself, and then boiled a pot of boiling water to boil the crabs, or fed them all to Li Yuxin, Li Yuxin insisted on keeping one for Cheng Ran, but under Cheng Ran's righteous words and threats, all the crabs were eliminated.

After these two days of recuperation, Li Yuxin's body has improved a lot, but her body is still very hot, but the meaning is indeed very clear, this is a sign of improvement, as long as she continues to persevere, the body's autoimmunity will help her recover.

"The crabs on these two days were the most delicious crabs I've ever eaten in my life for as long as I can remember." Li Yuxin looked at Cheng Ran with the Y eyes that slowly became gentle, she was not very good at expressing gratitude, in fact, she said this to thank Cheng Ran.

"If you like it, I'll go to the beach every day to catch it for you." How can a single dog like Cheng Ran, who has been single for more than 20 years, resist the gentle eyes from Li Yuxin, but just happened to meet them, and his face turned red and quickly turned his head.

Seeing Cheng Ran's reaction, Li Yuxin smiled smugly in her heart: "Cheng Ran, why are you red." ”

Cheng Ran's mouth was so hard that "let this fire roast." ”

Li Yuxin's secret smile made Cheng Ran even more embarrassed, and at this time, both of them looked at the fire and were stunned, not knowing what they were looking for.

"Cheng Ran, I think this period is my happiest days, now that we have fire and some tools, our future life will definitely get better and better; Sometimes I think it would be nice if we stayed on the island for the rest of our lives. Li Yuxin held her chin with her hand and said with longing in her eyes

Cheng Ran smiled and said, "No, I believe someone will come to save us." ”

Cheng Ran didn't want to tell Li Yuxin the truth about this island until now, he knew that this was just Li Yuxin's current thoughts, and now it was just a whim that no one would stay on this isolated island, but now he didn't know where the island was, and it was impossible to talk about it when he went back.

So now Cheng Ran doesn't dare to tell Li Yuxin, for fear that Li Yuxin, who is already weak, will not be able to accept it for a while, which will make her body worse.

The two gradually opened up the topic and chatted a lot, including their previous work and life, as well as interesting stories about their lives when they were children, but in the end they returned to how to live on this island in the future.

Now there is water, there is fire, and there is no shortage of food on this island.

"Why don't we try to build a house?" Cheng Ran suggested

"We want to build a house, but we don't have the tools or materials." Li Yuxin said with some reluctance

In fact, Cheng Ran also knew and thought about these questions, and he also understood Li Yuxin's thoughts, but after thinking about it many times, he still insisted on this decision.

This island is a tropical island, the climate on the island is unpredictable, just like before, one second the sun is shining, the next moment there is no warning of the downpour and wind, if the biggest problem like now is how to preserve the shelter and the fire, if the two live in the house, at least there is no need to worry about the fire being extinguished by the heavy rain.

After the process lasted for half an hour, Li Yuxin began to slowly accept this proposal, which was indeed much more stable than now.

"It's a bit small now, and it's a bit crowded with two people. Li Yuxin looked at the shelter and added: "I don't mean anything else, I just feel a little small." ”

"All we're going to build a house, yes! Build a bigger house. Cheng Ran said excitedly and firmly

Li Yuxin's body has not recovered because of the fever, so she is not so excited that she will talk endlessly.

Li Yuxin chatted for a while and began to yawn and said, "I'm a little sleepy." ”

"You can rest for a while, I'll make something."

Li Yuxin leaned next to Cheng Ran, closed her eyes, and fell asleep not long after.

Cheng Ran went to cut some wood, bamboo is easy to cut, but the bamboo is curved and hollow, which is obviously not suitable for use as a mold material, and wood is currently the most suitable.

Because it was the first time to make it, Cheng Ran planned to make a smaller mold first, and then make some larger molds after he became proficient in the follow-up, and make bricks in large quantities.

This time, Cheng Ran plans to try to make a small brick about three centimeters high, five centimeters wide and about ten centimeters long.

Cheng Ran didn't have nails in his hands, if he wanted to make a wooden mold that could be used for a long time, he had to use ancient techniques, he needed to cut the wood flat first, and then use fire to dig out a hole in the two ends of the long wood, and then sharpen both ends of the short wooden stick and insert it into the hole, only in this way can it be tied with rattan.
