After another week of school, Lin Nan's last winter vacation in junior high school officially began.

As soon as the holiday was over, at about two o'clock in the afternoon, Lin Wolf took Lin Nan and drove back to Linjiawan in the countryside.

Ye Xinlan is busy with things in the hotel, almost the end of the year, the hotel has also received a lot of orders for Chinese New Year's Eve dinner, pure local vegetables, fragrant pot porridge, is the taste of many people's memory, so the hotel's business is too good, causing Ye Xinlan to be very busy, she has to ensure that every table of guests are happy to welcome the New Year and eat a good Chinese New Year's Eve dinner.

The employees in the hotel watched the female boss busy before and after, and the sound of discussion was endless.

"The boss is really busy, I haven't seen the boss come to the hotel for almost a month!"

I heard that the boss has been with his son recently, and the boss's son is about to take the high school entrance examination. ”

"That's a lot of accompaniment, but isn't it usually outside the hands of men and women?"

"I don't know about this, but I think the hostess manages the hotel very well, no worse than the boss. ”

"When you say that, I suddenly find that the boss looks quite like a teacher, maybe the boss was an educator in his last life!"

"Wow, if you think about it, it really looks like eh!"

......

On the other side, the driving distance between Timber Wolf and Lin Nan finally ended, and they saw a closed gate, and there was a pool of fallen leaves in front of the door.

Park the car, open the doors and windows, and let the house that has not been lived in for a long time have a good breath.

In a few days, the Chinese New Year's Eve will be 30, and Lin Wolf and Lin Nan will come to the old house to make a front stop, and there will be a formal cleaning before the twenty-nineth.

Timber Wolf turned on all the lights in each room, and there was no accident, all of them were on, and it seemed that the last repair work was done well.

At this time, Lin Wolf suddenly heard Lin Nan shouting, "Dad, Dad, come and see, come and see ...... in the backyard."

Timber Wolf wondered a little, what's wrong with the backyard?

It seems that the last time I came back, I didn't open the back door, and naturally I didn't go to the backyard.

Timber Wolf passed the living room, and went directly to the innermost room, he remembered that he spent money to renovate the backyard during the summer vacation last year, and the grass, vegetable patch, and flower beds covered the entire backyard, and finally paved a stone brick road on the grass, the kind of red and green.

At that time, many people in the village came to see it, and they all came back to renovate the old house as soon as they went out to make money.

Logically speaking, there shouldn't be any problems, right?

Stepping through the back door of the innermost room, the timber wolf made his way to the backyard.

In an instant, he knew what Lin Nan was calling.

I saw that the entire backyard was already overgrown with flowers and plants, and the flowers in the flower beds and the grass on the grass were wildly multiplied, occupying the entire backyard, like a small forest.

It is very different from the neatly trimmed flowers and plants at the beginning.

The power of nature, without people's "care", relying on the sun and rain, they do not know how nourishing they can live.

Lin Nan was standing at the beginning of the stone brick road, there was no trace of "bricks" on the whole stone brick road, the brick joints were overgrown with weeds, and the withered yellow grass grew almost twenty centimeters high.

After searching for a long time and not finding where the road was, Lin Nan asked Lin Wolf curiously: "Dad, are these little grasses so tenacious? ”

The wolf replied with a smile: "Isn't it, otherwise how could there be wildfires that burn inexhaustibly, and the spring breeze blows and grows again?"

"Little grass grows in the cracks of the stones, let alone in the cracks of the bricks? ”

Lin Nan nodded, and saw Lin Wolf pick up a shovel under the eaves next to him, walk to the starting point of the stone brick road, and exert all his strength, facing the weeds is a shovel.

The shovel instantly plunged into the weeds, and the wolf raised his left foot and stepped on the iron hard, and the shovel went deeper, and then took off his left foot, and with both hands, he directly raised a large cloud of weeds, and the wolf threw it on the grass next to him.

The stone brick road only then showed a little bit of brick.

However, there are still sparse weeds that are closely connected to the cracks of the stone bricks.

It took a few more shovels to clear the stone road a step or two away.

Standing the shovel on the ground with one hand, Lin Wolf took a light breath and said to Lin Nan: "Today, our task is to restore this stone brick road to its original state and uproot all the weeds along the way. ”

Lin Nan looked at his father, who was a little tired after just a few swings, he opened a pair of big eyes, and asked very suspiciously, "Dad, is this very tired?"

The wolf chuckled, looked at his son, who had never done farm work before, handed over the shovel in his hand, and said, "You can try it." ”

Lin Nan confidently and excitedly took the shovel, shoveled it against the weeds, and then raised his left foot and stepped on it, and learned a set of movements.

However, when Lin Nan was about to pick up a large cloud of weeds, he found that things were not what he imagined.

He tried his best with both hands to pick up a cloud of weeds inserted into the shovel, but found that all his milk strength had been used, and the shovel just didn't move at all, and there was no response.

As if it was a jack pendant pressed on it, is the connection between the grass and the brick joint so tight?

Lin Nan felt a little incredible.

Do I need to dial a thousand pounds in four or two?

Lin Nan didn't have a clue.

After trying hard several times in succession, Lin Nan had to admit a fact - the shovel inserted in him couldn't lift it by himself.

He finally knew why his father looked a little tired after just swinging a few shovels, so Lin Nan cast a look at his father for help.

Timber Wolf took the shovel that had been inserted, arched his waist, and exerted his legs and arms at the same time, and soon picked up the weed, threw it on the grass beside him, and exposed a small block of stone brick road.

Looking at this stone brick road more than ten meters long, Lin Nan thought of the task that his father said, and couldn't help but feel how difficult it was, according to this progress, how long would it take!

Lin Nan's eyes rolled, as if he thought of something, he looked at the wolf and asked softly, "Dad, let's just burn it!"

"Are you thinking about fart?"

......

There is a ditch between the grass in the backyard and the house, and with such dense flowers and trees, isn't this self-immolation?

Seeing Lin Nan's somewhat deflated appearance, he may have been frightened by the workload and work intensity.

With a slightly mocking tone, Lin Wolf said to Lin Nan: "Son, when I was your age, I did all the heavy work at home with your grandfather, and I never complained, just a few weeds scared you?"

"Of course not!" Lin Nan replied without thinking, he could do what his father could.

Young and frivolous, never admit defeat!

Snatching the shovel in the hand of the forest wolf, Lin Nan started to dry up against the weeds on the stone brick road.

This time he learned wisely, and instead of sticking the shovel deep, he lifted it up almost halfway.

Lin Nan knew very well that his strength was not enough, and he would not be able to jump no matter how deep it was.

Seeing that Lin Nan wittily made the right change, Lin Wolf was very happy, and finally said to Lin Nan: "Remember to say when you are tired, let's change it, don't overexert yourself." ”

These words aroused Lin Nan's determination of perseverance, and it seemed that he would not change it if he was not tired and paralyzed.

However, Lin Wolf is not worried about Lin Nan's body at all, because he has a "body strengthening medicine", which specializes in treating all kinds of bruises, overwork, and no side effects.

Especially for Lin Nan, who is growing her body, the medicinal bath after exercise can also stimulate the body and promote the growth of height.

According to Lin Wolf's estimate, Lin Nan should be able to grow to 183 under his conditioning and teaching in this life.

Hmmm! just as tall as the AI he likes.

So, the wolf looked at Lin Nan quietly on the side.

In just 15 minutes, he was defeated, and the stone brick road was only more than half a meter advanced.

It's not that Lin Nan can't persevere, but he really needs to rest to recover his strength, and the progress of weeding with the only remaining strength is too slow, for the sake of the task, Lin Nan decisively asked his father to take over.

Lin Wolf's progress is much faster, after all, he is a child who grew up in the countryside, and he has done all kinds of farm work since he was a child, and a shovel makes it very skilled, which is completely different from Lin Nan's empty movements.

Every ounce of effort, the wolf spent it where it should be, and never wasted a single bit.

Looking at his father's rapid progress compared to himself, Lin Nan knew that it was not only the gap in strength, but also the reason why practice makes perfect.

Looking at the grass on the grass again, Lin Nan touched his yellow-green body and swayed with the wind.

Why are you so tenacious?

Lin Nan decided to go home at night and check it on the computer.

Dozens of minutes passed, and the wolf had already cleared one-third of the stone brick road, handed the shovel to Lin Nan, and the wolf went to the stone bench to sit down and rest.

Lin Nan gritted his teeth and shoveled for another 15 minutes, shoveling his whole body with all his might, and it was the turn of the wolf to go into battle again.

In this way, hours passed, and a red and green stone brick road finally appeared in front of the father and son.

Lin Nan dragged his tired body and walked around the stone and brick road, jumping from time to time.

Take a good look at the fruits of your labor.

It was getting late, and at dusk I saw two figures of similar height, standing on the stone brick road among the flowers and grass, and the two shadows were stretched narrow and long under the sunset.

A calm and steady, but also energetic.

A vigorous and wanton flying.

After a final glance at the fruits of the afternoon's labor, Lin Wolf and Lin Nan walked into the house and locked the back door.

Touching his hungry flat belly, Lin Nan came to the kitchen to help Lin Wolf live and cook.

The man's meal was very easy to solve, Lin Wolf made a big pot of pot porridge, and Lin Nan ate four or five bowls of it alone.

The fragrant pot porridge, never tired of eating, the father and son who are stuffed with a full stomach, and their tired bodies seem to be full of strength again.

When he got home, Lin Nan walked to the study as soon as he entered the door, turned on the computer and searched for "Xiaocao's tenacious vitality".

After 100 degrees, I found that all the essays or poems praising the vitality of Xiaocao did not explain the reason for the tenacious vitality of Xiaocao.

After thinking about it, Lin Nan searched again for "the reason for the tenacious vitality of Xiaocao".

After browsing for a while, Lin Nan roughly understood that the tenacity of the grass should be created by the development of the roots.

The roots of small grasses have taproots, lateral roots, and adventitious roots. It is mainly the root hairs that absorb water and inorganic salts, the cell wall of the root hair is very thin, the cytoplasm is close to the cell wall to form a thin layer, and the center of the cell is a large vacuole, which is filled with cell sap. This structure is suitable for absorbing moisture.

Under the action of osmotic pressure, the water in the soil solution can penetrate the cell wall, cell membrane and cytoplasm into the vacuole of the root hairs, and the soil water is absorbed by the root hairs.

In addition, grasses generally have fibrous roots, and the roots are also very long, which can be fixed more firmly in the soil, and can grow faster by grabbing the nutrients of crops.

......

After some reading, Lin Nan roughly understood the reason for Xiaocao's vitality, and at the same time, it was more like walking into a wonderful biological world.

As everyone knows, he has planted a small seed for high school biology.
