"There was a cactus patch there, and it was also growing a lot of cactus fruit."

"Many of those prickly pears have turned red; they're ready to eat."

"Judging from the left side, there's a mangrove forest, which must contain a lot of blue crabs."

“Look at this video. It seems we’re not far from Group C’s camp.”

"Fatty girl, go up the hill to catch blue crabs in the mangroves."

"Looking forward to the meeting between members of Group A and Group C."

The screen was flooded with comments, all eagerly anticipating the chubby girl and her friends' ascent uphill.

"That's enough for today. It's getting late, we should head back," Li Xiang suggested, noticing that Liu Yifei looked tired after walking for so long.

"Alright, let's head back then," Li Yinsheng said, glancing at Liu Yifei.

When the viewers in the live stream heard that Fatty and her friends were heading back home, the chat started flooding with comments, all typing the word "uphill".

It instantly went viral.

When Li Yinsheng and the others returned to the camp, the three leaders had already returned and started a fire to roast the crabs, conches, small fish, lobsters, and yams they had caught while beachcombing.

Li Yinsheng rinsed the passion fruit tips she had picked, chopped them up, and mixed them with some clam meat to make a cold dish.

After breakfast, the six of them began building their shelter.

The shelter was crucial to their survival, so everyone devoted a great deal of energy to it.

Using his extensive experience, Li Xiang was in charge of planning and designing the shelter's framework. Yesterday, he not only dug the foundation but also built a section, completing one-third of the project.

Today's work is easier; we just need to carve out the mortise and tenon joints on each tree and then install them one by one.

The leader and Fatty continued to be in charge of cutting down trees. They were both strong and worked efficiently. Zhang Yixing and Li Xiang were in charge of building the shelter, while Zhao Liying and Liu Yifei were in charge of moving the wood to the shelter. Each of them did their job and were extremely efficient.

Around noon, Li Yinsheng cooked another pot of thick white porridge, grilled the two remaining lobsters, and let everyone rest in the shade.

They sat together, and although everyone was tired, they were filled with satisfaction and a sense of accomplishment as they saw the shelter gradually taking shape.

In the afternoon, they continued their work. As time went by, the framework of the shelter gradually improved, and the roof began to be built. Finally, at five o'clock in the afternoon, the shelter, constructed with mortise and tenon joints, was completely completed.

"We've finally finished building our shelter!" Liu Yifei said with a happy smile, lying down in her newly built shelter without any regard for appearances.

Today's work was more arduous than usual, but she felt it was all worthwhile. Watching this sturdy shelter take shape bit by bit in her hands, she knew the process was tiring and difficult, but the joy and satisfaction she felt upon completion was overwhelming.

Although the shelter was simple, it was enough to withstand the wind and rain, providing them with a safe haven. Moreover, the shelter was a symbol of their joint efforts and struggles.

"Tomorrow, we'll stuff moss into the gaps between the trees on the sides of the shelter, weave some straw mats to keep out the wind and rain, cover the roof with a layer of thatch and banana leaves, and then weave another straw mat in the middle of the shelter. This way, it can become two shelters, one for men and one for women."

Extend a few pieces of wood outwards to build a storage room for food such as timber and coconuts.

"We'll make some more arrangements tomorrow, and the day after that we'll focus all our efforts on finding food." Li Yinsheng took over Liu Yifei's words, looking at the shelter with anticipation in her eyes.

“I think we should put a fireplace at the entrance of the shelter so that it won’t be difficult to cook outside on rainy days,” Li Xiang suggested.

“Then let’s start working on these things tomorrow,” Li Yinsheng said with a smile, full of anticipation and confidence for life on the deserted island.

"Wow! The shelter built by Group A using mortise and tenon joints is really impressive. Compared to the other groups, it's practically a luxury villa."

"My Yingbao and Qianqian worked so hard today. I didn't expect them to be able to persevere and do such heavy and tiring work."

"The mortise and tenon technique used by Group A to build the shelter is truly worthy of everyone's learning, with its ingenious structure and stable performance."

"Well done, Group A."

"Group A is amazing!"

"Their shelters are not only beautiful and practical, but also full of the charm of traditional Chinese culture. This is true craftsmanship!"

Viewers watching the live stream witnessed firsthand the construction process of Team A, and their emotions rose and fell with the events.

"Look, mortise and tenon joints are a national treasure; this is the charm of traditional Chinese woodworking techniques," an old carpenter commented in the live stream.

"The mortise and tenon technique requires no nails; it achieves a sturdy and durable effect solely through the interlocking structure between the wood pieces. Group A's choice is undoubtedly the best tribute to traditional techniques."

What the members of Group A didn't know was that they were not just building a shelter, but also passing on a spirit—a love and respect for traditional culture.

This live stream also allowed more people to understand the charm of mortise and tenon joints and feel the profound heritage of traditional culture.

That evening, the shelter built by Group A was completed and immediately became a trending topic on Weibo.

"Survival on a Desert Island: Team A builds a shelter using mortise and tenon joints, showcasing the inheritance and continuation of intangible cultural heritage."

Immediately, netizens liked and shared the post, and discussions arose one after another.

"This is our traditional culture, it's amazing!"

"Group A is really amazing. They gave me a new understanding of woodworking techniques."

In the evening, I roasted the last of the yams, picked some wild vegetables, and cooked a pot of them for a simple dinner.

The cult leader went to check the traps set up that day, but as expected, he found nothing.

After finishing dinner, Group A rested for a while. Once it got dark, they took their spearguns and headlamps and went diving to fish again.

Dinner was simple tonight, with no meat, so everyone's hoping to catch some fish while diving tonight so they can have a late-night snack.

"Master, let me put a few fishing hooks on the seabed and see if I can catch any fish tomorrow." Li Xiang had already made a few stone hooks. After handing the harpoon to Huang Xiaoming at the beach, he took the stone hooks and plunged into the sea.

The so-called stone fishing involves wrapping the fishing line around a rock, placing bait on the hook, and when a fish takes the bait, the line is pulled taut, and the weight of the rock prevents the fish from escaping.

This fishing method doesn't require constant monitoring; once the fishing spot is set up, you only need to check on it morning and evening.
