"Hmph!" Wu Yicai stroked his hair very confidently, "Of course it's going back!"

"I'll go, big brother, this big piece of wood is so big, you want to roll him back?" The corners of Han Lingshuang's mouth twitched, how can this thing roll back.

"You wait and see, let you see the highest level of the principle of leverage!"

This section of the log is a regular cylindrical shape that rolls well on hard ground and can be rolled out far with a slight warp.

Half an hour later......

Wu Yicai collapsed on the sand, the log rolled quickly on the hard ground, but the beach was so soft that it couldn't move quickly at all, and it felt like it was stuck in the sand.

"It turns out that this is the highest level of the principle of leverage!" Han Lingshuang laughed with both hands, "Today I can be regarded as a long insight. ”

"You have the skills to taunt me, you might as well help do some work. Wu Yicai responded lightly, feeling extremely embarrassed in his heart, he wanted to pretend to be forced, but he lifted a stone and shot himself in the foot.

"Say it, my genius little brother!" Han Lingshuang squinted and tilted her head slightly, and then asked, "What do you want me to do for you?"

"Let me think about ......"

Originally, the log could be rolled quickly on the ground, but the sand was too soft and it was very difficult to roll.

If you add something to the rolling track of the log, make it something like a track, and it will travel along the track.

It's like the construction of pyramids in ancient times, so many huge rocks lift up a behemoth, and the weight of the huge stones is simply not something that can be moved by human power.

The highly intelligent ancient Egyptians came up with an excellent way to use the rolling power of the rolling log, which was pulled by multiple people with ropes.

Under the action of pushing force and rolling force, the boulder can easily be transported conveniently, saving time and effort.

It is now possible to imitate the method of rolling wood and dragging stones invented in ancient Egypt, but it is reversed.

After deciding on the method, Wu Yi looked around, and finally saw some tall and straight trees, which would be the best material for moving logs.

"Now let's go and cut some trees in the forest over there and use them to make a track on the ground!" Wu Yicai said to Han Lingshuang, who was grinning on the side and was about to continue to taunt him.

"Track?" Han Lingshuang frowned, could it be that this guy had figured out a way to transport this big piece of wood?

"Let's cut down some small trees, straight ones, the same length as possible, about four is enough. ”

"There are some straight trees over there, and you can lay two trunks parallel to each other at 3 metre intervals on the beach to make a track out of the sand and roll logs on them. Wu Yicai explained his theoretical ideas.

"This greatly reduces friction and the skin of the trunk is completely smooth, allowing the log to roll all the way on. Wu Yicai stretched out a finger, "I can effortlessly roll this log back to the shelter!"

"This ......" Han Lingshuang was sincerely shocked by the smooth theoretical logic of this product.

"Wang!" Wangcai also shouted in order to highlight his presence, and then lay on the beach and began to roll around.

"This product has been very happy lately......"

After making their initial plans, the two and their dog headed towards the interior of the coconut grove, where there were some straight trees and little clutter of branches.

Originally, Wu Yi wanted to use bamboo as a track, but later when he thought about it, he felt that it was not advisable, so he gave up.

There are two reasons for this!

First, it's too far away from the shelter to travel back and forth.

Second, the inside of the bamboo is hollow and can be easily crushed by the gravity of the logs.

Although the sand below is soft and has a certain cushioning capacity, which can play a role in shock absorption and weight reduction, this place is far away from the shelter, and if half of the bamboo bursts, it will be troublesome.

There's an old saying that if you walk around and see more, something unexpected will happen.

In this rather dense forest, there are not only straight and unknown trees, but also a delicious fruit.

Big red dates!

"Huh!" Han Lingshuang immediately discovered those red shimmering fruits, and then it was like discovering a new world. "There are big red dates here, and they grow so big, and there are so many ......"

Wu Yicai also recognized this fruit, when he was a child, he went to the mountains to steal it with his friends, and later was caught, and after some questioning, he knew that it was still a relative of his own.

In terms of seniority, he should be called grandpa, and since then, if you want to eat dates and peaches, you can just pick them directly......

"This isn't poisonous, right?" Han Lingshuang showed the side of a foodie girl again, but she wasn't sure if this was the big red date she was familiar with.

"It's not poisonous, there are a lot of these big red dates in my hometown. ”

The big red jujube looks red and oval, about the size of a mountain egg, and there are some lovely fruits hanging here and there on this jujube tree.

Most of the dates ripen quickly, have fallen to the ground, and are somewhat dry and flat.

The dried and flattened dates lose a lot of water, and some hanging on the tree have plenty of water.

I picked a big red jujube and wiped it clean, the surface of the jujube was oily and shiny, and it was very appetizing to see it.

"Click!"

Han Lingshuang's speed was the fastest, and he bit it down in a small bite.

Jujubes taste crisp and delicious, sweet and fragrant, and although the juice in the pulp is scarce, it is particularly sweet.

"It's so sweet! It's delicious~!" Han Lingshuang's delicate little face was filled with a happy smile, making people look like bathing in a spring breeze.

Wangcai also likes to eat red dates, and those that fall on the ground are rotten or wrinkled and lose moisture, and they don't eat them directly.

"Mmmm~!" Wangcai stood up as if he was coquettish, hugged Han Lingshuang's slender long legs with his front legs, and then asked for big red dates.

"Wangcai, you can eat too much, didn't you just give you two?" Han Lingshuang blushed and pouted, "I haven't finished eating this one yet!"

This little girl is so cute!

"If you like to eat, eat more. Wu Yicai touched Han Lingshuang's little head dotingly, "We will also take back these dates on the ground, pick the ones that are not rotten, and put them in the sun to expose them to the sun, and remove the excess water and store them for a long time." ”

There are not many hard dates, only a dozen, and most of them are rotten on the ground, which is estimated to have been pecked by birds and fell.

There are also dozens of dried and wrinkled jujubes, with a little moisture in them, and they are put away and taken back to dry.

Originally, I came to fetch the long pole, but there was an unexpected harvest, sawing off the straight trunk and removing the excess branches, and came to the beach again.

The road was extremely easy, and the huge log rolled into the house, and Wu Yi sighed again, there are still intelligent creatures that can survive more easily and comfortably in the wild!

Now it's time to get ready to start building the boat!
