In the morning, Li Ling woke up and saw Wang Lun lying next to her. She felt her hand on Wang Lun's chest and quickly pulled it away, but Wang Lun didn't react. So she quietly took a piece of thatch and gently scratched the tip of Wang Lun's nose. Seeing that he still didn't react, she continued. Wang Lun finally opened his eyes and said, "Stop it, it tickles." Li Ling was startled, then realized what she meant and said, "Who told you to pretend to be asleep? Otherwise, would I have bothered you?" Wang Lun was speechless, wondering if he was in the wrong again. He said, "But it was your hand on my body." Li Ling, ignoring everything else, said, "Never mind that, pretending to be asleep is wrong." Wang Lun was speechless and said, "Fine, I was wrong." Li Ling said, "Okay, then I'll punish you by making breakfast." Wang Lun could only nod and say, "Okay, I'll make breakfast." He got up, grabbed a pot, and left the shelter. Seeing this, Li Ling decided to lie in bed a little longer and sleep in. After all, it had been a long time since she had slept in, so she decided to take advantage of the day and sleep in.

Neither of them talked about what happened the previous night. Li Ling felt embarrassed to discuss it, while Wang Lun, being a rather traditional person, decided that since they had already slept together, he would treat Li Ling well from now on. Whether it was his previous affection or his current sense of responsibility, these were the reasons that led to this. In addition, Wang Lun was not a talkative person, and he believed that actions speak louder than words, so he kept quiet. Thus, neither of them spoke of it, but they maintained this tacit understanding.

Wang Lun left the shelter, fetched water from the pool, and returned to the campfire. Seeing some embers, he gathered some weeds and firewood, lit the fire, and added more. He then placed the pot on the fire. He went to wash up, and after washing, returned to the shelter, grabbed a dried fish, some seaweed, and a handful of wild vegetables. Seeing that Li Ling hadn't gotten up yet, he said, "You can get up now. Breakfast is ready after you wash up." Li Ling responded. Seeing that Li Ling understood, Wang Lun prepared the ingredients and then cooked breakfast. He first added the fish pieces, then the shredded seaweed, and then the wild vegetables. After adding everything, he stirred it a few times with a spoon, tasted it, and found it quite delicious. At this time, Li Ling also got up, washed up, and came to sit by the campfire, waiting for breakfast.

After a while, Wang Lun thought it was cooked, so he took the pot off the stove and set it aside. He first served Li Ling a bowl, and then served himself. Li Ling tasted it and said, "It tastes good! From now on, you'll be in charge of breakfast." Wang Lun was speechless for a moment and said, "Didn't I say I'd only cook one breakfast this morning?" Li Ling said playfully, "I've changed my mind, is that not okay?" Wang Lun said, "Okay, then cook it." Li Ling suddenly leaned in and kissed him, saying, "This is my salary." Wang Lun's eyes lit up and he said, "Okay, remember to pay me every day." Li Ling said, "Dream on, it depends on my mood." Wang Lun then smiled and said, "Okay, I'll decide based on my mood from now on too." Li Ling was unwilling this time and said, "Fine, I won't give you any." Wang Lun smiled and said, "That's more like it." Li Ling felt she had been taken advantage of, so she stopped talking about it, afraid that if she waited any longer, things would get heated. They were both engrossed in the task, so they asked, "Are we starting to build the mud house today?" Wang Lun took a sip of soup and said, "Yes, I marked the locations of the wall and the mud house with wood ash. If you have time, dig a foundation for the wall first, not too deep, about twenty centimeters will do. I'll go cut down some trees." Li Ling said, "Shall we build the wall first?" Wang Lun said, "Yes, let's build the wall first, it will be safer when we build the mud house." Li Ling said, "That's true, but I'm afraid I won't finish digging the foundation for the wall this morning." Wang Lun said, "It's okay, I can dig it after I finish cutting down the trees. Let's eat quickly, there's still a lot to do today." Li Ling nodded, and the two of them ate quickly.

Wang Lun finished the last bit of soup in his bowl, saw there was still a little more than half a bowl left in the pot, so he put down the bowl and said, "I'm going to chop down some trees first. You clean up the pot and dishes." He then put down the bowl, grabbed his machete, and went out of the fence. Li Ling said, "There's still rice left. We can't finish it." Wang Lun didn't care, since he knew how much he had cooked, and he had also figured out how much they both ate over the past few days. They both ate about the same amount; Wang Lun felt he was only about six-tenths full, and he guessed Li Ling was about the same. Anyway, he wouldn't be too full from that little half bowl, so he figured Li Ling might as well eat it.

Seeing Wang Lun leave the camp, Li Ling poured the last bit of food from the pot into her bowl, ate it in a few bites, and said, "Uh, a bit little, only half full, forget it." She then started cleaning up the pot and bowl. After finishing, she went to find the wall lines Wang Lun had drawn. She saw the lines Wang Lun had drawn as soon as she left the fence. First, there was the location of the earthen house, about seven or eight meters long and three meters wide. The shelter platform was about three meters wide, and the platform above it was also three meters wide, totaling six meters, with a total area of ​​over forty square meters. Then, after passing the earthen house, the wall was another seven or eight meters ahead. Li Ling estimated that the wall for this platform alone would be against the earthen cliff at both ends. She decided to build the wall on this platform first, and later, when there was time, or during other times, gradually build the wall for the platform behind it. Because of the height difference, the wall for the platform behind wouldn't need to be three meters high; one or two meters would be enough, although the thickness would be roughly the same. Li Ling considered the situation and realized there were many things to consider, so she stopped thinking about it and quickly got to work.

Wang Lun, still busy in the jungle, first cut down seven large trees, each about twenty or thirty centimeters in diameter, then trimmed their branches. These were to be used as beams for the earthen house; he cut them in advance so they could dry slightly beforehand and be carried back. Next, he cut down more than ten small trees, each about ten centimeters in diameter, to make two doors. After clearing away the branches, he estimated he had enough horizontal beams for the wall, but not enough vertical ones, so he cut down about twenty small trees, each five or six centimeters in diameter, or branches from larger trees. This was enough, so he bundled the branches for the wall. He bundled two thicker bundles and five thinner bundles, then moved the dozen or so small trees together. As for the large trees, one person couldn't carry them, so he would call Li Ling later, and the two of them would carry them back together. Because they needed a lot of trees, Wang Lun didn't run far; it would only take about ten minutes to get back. So, he first carried back the two bundles of thick branches for the vertical sections of the wall. When he got back to the camp, he saw Li Ling still digging the foundation for the second wall, and she had only dug about a meter from the end. So, he called Li Ling over, and the two of them carried back the five bundles of thin branches. Li Ling carried two bundles, and Wang Lun carried the other three. When they returned to the camp, sweat was dripping from Li Ling's hair. Wang Lun poured a bowl of water for Li Ling, who was sitting by the campfire, and poured one for himself. After drinking, he said, "It's getting late. You stay at the camp and rest before preparing lunch. I'll go back again." Li Ling nodded. Although she really wanted to go back, she was exhausted. She had spent the whole morning digging the foundation and then carrying two bundles of branches. So, Wang Lun went out of the camp alone again.
