"Tuk-tuk, tuk-tuk, tuk-tuk. 【△ Net】. ”

Yesterday was a little tired, and Lu Feng was woken up by the movement of the pair of spotted woodpeckers above his head trying to build a new home.

Letting go of the front paws holding his head, Lu Feng rushed out of the nest, elongated his body like a cat, his back was lowered, his front and back limbs stretched hard, and he stretched his waist greatly.

The sixty-first day of the squirrel calendar.

There is no sunshine today, and it seems to be cloudy weather.

Picking up a hazelnut from the nest, Lu Feng looked up at the spotted woodpecker working hard and began to enjoy his breakfast.

It has to be said that parents who work hard for their children are the toughest.

It's just a difference of one day, the cave pecked out by the spotted woodpecker couple is already half a bird's body deep, although it has the help of silverfish erosion, but the progress of this project has to make Lu Feng give a thumbs up.

Attaboy!

After eating breakfast, Lu Feng came to the [whiteboard] as usual, marked the beginning of the next [positive] character, and then went into the tree hole.

"Rustle, rustle...

In the depths of the tree hole, Lu Feng's eyes flickered with a faint light. Squirrels have nocturnal vision and only need a small amount of light to see their surroundings clearly.

Gnawing at the trunk of the big pine tree with his front teeth and pushing the gnawed sawdust out of the hole, Lu Feng worked hard to build a new home.

However, after completing each cycle, Lu Feng would use his body to measure the depth of the tree hole as he entered the hole, and he was ready to dig the tree hole to the center of the big pine tree before starting other operations.

It should not be too shallow, too shallow will affect the stability of the trunk of the large pine tree, and at the same time it is unsafe, and it should not be too deep, too deep will be overdug.

Lu Feng naturally didn't know that the diameter of the big pine tree was more than two meters, but he climbed on the trunk of the tree and measured it with his body, which was about eighteen Lu Feng's length from head to tail, and it could be easily concluded with the circumference formula of the circle that the depth of the tree hole was about three Lu Feng reached the center of the trunk of the big pine tree from head to tail, and Lu Feng's maximum step was about one-fifth of his length.

One step, two steps, three steps... Fifteen steps! Almost!

If there is no deviation in the direction, this should be the heart of the big pine tree!

After completing the sixteenth cycle of today, Lu Feng measured the depth of the tree hole, and then drilled out of the tree hole.

However, before the vertical operation, Lu Feng still needs to plan well.

Looking at the sky vigilantly, he didn't find the whereabouts of [Gray Feather], and held his breath again, his big ears spun from side to side, and he didn't receive any other sharp critter chirps.

No danger, nice and safe!

Nodding with satisfaction, Lu Feng jumped down from the big pine tree and came to the east of the pine tree.

Less than ten meters from the large pine trees is a cliff with a large flat gray rock at the top of the cliff exposed, and only between the crevices of the rocks, some weeds and moss grow.

Lu Feng jumped over the weeds, picked up a small sharp stone chip that had been weathered down with his flexible forelimbs, and came to this gray cliff rock.

The wind was very strong, there was not a trace of dust on the gray and white rocks, and the long hair on Lu Feng's tail and the beard on the side of his mouth were also shaking with the wind, making him look quite messy.

In spite of!

Anyway, I'm a squirrel now and don't need to pay attention to the image!

Aim the sharp end of the stone chip in your arms towards the flat side of the rock, and press down so hard that the rock rubs a white line between the rocks. Tossing and turning, holding the small stone chips, Lu Feng kept retreating and turning around, and line segments appeared on the gray and white rocks.

Two lines were drawn on the outermost side, representing the outer diameter of the large pine tree, and then two parallel lines were drawn at very small intervals, one end of which was connected to an outer line, and the other end was straight to the center of the two outer lines. It represents the tree hole passage that Lu Feng has dug up.

Then, Lu Feng held the stone slic, moved his body in small steps, and drew an ellipse at the end of the parallel horizontal line little by little.

No way!

It's so easy! It's not safe either!

With his little head sideways, Lu Feng immediately vetoed the first plan, digging a tree hole directly at the end of the tree hole as a nest, and making it a warehouse, a storage room, and a bedroom, in addition to being firm and stable, what is the difference between it and the current nest?

After resting his head on the stone chip held by his forelimbs and thinking for a moment, Lu Feng drew on the gray and white rock again.

Two lines, a circle, two lines, a circle, Lu Feng did not stop until he drew two circles in a row on the first circle connected to the tree hole, and a circle on the lower part connected to the tree hole passage.

The topmost circle serves as a bedroom, the second circle serves as a storeroom, the third one connected to the tree hole passage serves as a living room, and then the bottom circle serves as a toilet.

Well, that's all! What a genius this rat is!

If there is someone next to you at the moment, you will definitely be shocked.

Your sister! After the founding of the People's Republic of China, animals are not allowed to become sperm? Is it not allowed to become a sperm? So what is it about this squirrel holding a piece of stone and nodding at the abstract painting on the gray and white rock, and still looking like he has gained something?

At the moment, naturally, no one will be around.

With the sketch in his mind, Lu Feng threw the stone chips aside with his claws, crossed the weeds again, climbed the big pine tree, and got into the tree hole.

Energetic! Get to work!

I bite, I bite, I bite!

The sky was cloudy today, the sky was a little overcast, and yesterday brought back forty hazelnuts, Lu Feng had no intention of going out to forage for food today, so he started digging holes with all his might.

Compared to the difficulty of the passage, it is much easier to dig a circle at the center of the tree, starting from the center of the big pine tree and digging around in a circle, digging until it is about the diameter of Lu Feng's body and the length of the tail that can be straightened, and then it begins to go upward.

For a whole day, Lu Feng's mouth did not stop squirming, and he even had a feeling that his two pairs of front teeth had been shortened a lot, but the results of his work were also quite happy.

It was dark, and Lu Feng pushed the last pile of sawdust out of the tree hole of the day, and climbed up the branch where the nest was located with some difficulty.

Damn! It's tiring!

Even the front teeth are sour! It won't really be shortened, will it?

Leaning on the edge of the nest, Lu Feng was weak, and even touched his front teeth with his front paws before taking out the hazelnuts from the nest and eating them, which seemed to be really short, which scared his little heart a lot.

However, he immediately recalled the introduction that Uncle Zhao had made in [Man and Nature] in a deep and deep voice.

[Squirrels, like other rodents, do not stop growing their front teeth throughout their lives, but they eat nuts all their lives, and their living environment is full of trees and materials that can wear out their teeth, so they don't need to deliberately look for things to grind their teeth. 】

Fortunately, the front teeth will grow on their own, otherwise it will be a big loss!

However, you can't be so desperate, otherwise, the new home hasn't been dug yet, and this rat life may be sent first!

While nibbling on hazelnuts, Lu Feng was making plans for the following days, he decided to dig holes for half a day and forage for food for half a day, otherwise his physical strength and perseverance would be too cruel!

The autumn days are short, Lu Feng finished gnawing hazelnuts not long after, night fell, the mountains and forests from time to time sounded the cries of all kinds of nocturnal small animals, Lu Feng drilled into the nest, sealed the nest with grass wool and hazelnuts, in the swaying of the mountain wind, into sleep.
