After eating at noon, Lu Dongye and the village chief sent the things he bought for the villagers one by one.

Most of the houses in the village are now empty, and most of the people who still live here are elderly.

Lu Dongye watched them thank themselves hard, and he always felt even more uncomfortable in his heart.

Few of these old people still have wives, most of them are lonely and single, and their wives have long since gone west, leaving them alone for the rest of the years.

They are like a group of people who have long been forgotten by the world, they can't do anything, and they can't contribute to the environment around them.

In addition to helping the younger generations take care of the children left behind in the village, the only sense of existence of the old people is probably to reunite as a family during the Chinese New Year.

They don't eat much, and most of the time they can only sit at the dinner table and quietly watch the young people chat.

Young people don't understand the topics they want to talk about, and they don't understand the topics that young people talk about.

Lu Dongye wanted to accompany the lonely old people, but he couldn't bear to face their old faces, and he couldn't understand their memories of half a century at every turn.

On the way back, the village chief sighed vigorously: "The village is getting more and more empty, many old people have left, and young people are not even coming back for the New Year." ”

Lu Dongye could only nod and be silent.

People go to higher places, water flows lower places, life becomes better out of the mountains, and no one wants to go back to this poor place.

In addition to sighing, Lu Dongye's heart suddenly moved...... If Nanling Primary School gets better, will the lost population come back?

Just thinking about it slightly, Lu Dongye sighed helplessly.

No matter how good it is, it's just a primary school in a mountain village, can it be better than in the town and county?

Besides, there are many parents who don't want their children to go to school at all!

After returning in the afternoon, Lu Dongye gave Chen Muqian a half-day off to let her rest well.

Li Xiaoyu was on crutches, and many things were not very convenient, so Lu Dongye simply gave her a holiday and took on all the children's classes in the afternoon.

Of course, the most important thing for him to do this is that he wants to see for himself what the primary energy mask does.

At the beginning, Lu Dongye didn't notice any difference between the children, just like Chen Muqian said before, the children answered questions very positively, and their associative ability, as well as their learning and comprehension ability have been significantly improved.

But Lu Dongye understood that these were all brought by the primary spiritual cover.

So, what about the role of the primary energy mask?

Gradually, Lu Dongye understood a little.

Afternoon is also the time when it is always easiest to get sleepy, even if the children have taken a lunch break, it is inevitable that they will still be easily distracted.

Therefore, some sub-departments are usually arranged in the afternoon.

Lu Dongye has taught a lot of afternoon classes, and at this time, the children's energy is low, even if they are not drowsy, they will inevitably yawn for days.

This afternoon, however, the children's spirits are as good as they were in the morning!

No child yawns, and no child is drowsy.

Looking at the children who were also positive, Lu Dongye was happy in his heart, but he was also a little surprised, it turned out that the energy cover is literal, and staying here can make people's energy better.

If you have more energy, you will be able to concentrate, learn things faster, and remember things more firmly!

Lu Dongye deeply understands that people's energy is limited, and the time that can really concentrate every day is probably only about 5 hours.

This is the norm, and the gifted are not among them.

Ordinary people, during this time, whether it is studying or working, are the most efficient.

Handle anything, and have a calmer mind.

But after this period of time, all abilities will not be so good, and the mind will start to become a little confused.

And this energy cover can actually help people increase their energy!

Lu Dongye was suddenly a little overjoyed.

This means that the children in other schools only have 5 hours a day to really concentrate, but the children in Nanling Primary School really spend more time concentrating every day than they do!

Primary energy cover + primary spirit cover is simply the most suitable combination for stupid birds to fly first!

Gradually, Lu Dongye also noticed some differences in himself.

In the past two days, although he did not feel very tired physically, his spirit was a little tired.

However, standing on the podium to give a lecture, Lu Dongye felt that his mind was very calm, his thinking was also very clear, and his whole brain was refreshed.

In order to try whether it was the role of the primary energy mask, Lu Dongye deliberately stepped out of the scope of the energy mask under the pretext of pouring a glass of water.

At first, he didn't feel anything, but after just a few seconds, Lu Dongye could sense that his energy was gradually declining, and he couldn't help but yawn when he walked to the cafeteria to catch the water.

But!

When he walked back to the classroom, that feeling of clarity of mind returned.

The afternoon's lessons were all taught by Lu Dongye alone, and he carefully observed and found that not a single child yawned throughout the afternoon.

This fully explains the role of the energy mask!

When school ended at dusk, Lu Dongye, the last to come out of the classroom, couldn't help but stretch comfortably, with a relieved smile on his face.

He could feel that the children were making rapid progress, much more efficiently than before!

Watching the children gradually walk away one by one, Lu Dongye suddenly noticed that under the dusk sunset, there seemed to be a figure shuttling in the not too dense fruit forest on the hillside.

"Who went to pick wild fruits so late?"

The distance was too far for Lu Dongye to see which villager that person was.

Generally speaking, the villagers who want to eat wild fruits will go up the mountain to pick some fruits to eat in the daytime when there is enough light, and in his memory, he has never met anyone who goes to pick wild fruits in the evening.

After all, there are often other wild beasts in the mountains, but they are afraid of the lights in the village, and no one in the village raises large livestock, so there have never been any wild beasts attacking the village.

However, Lu Dongye has also seen many fruit trees, leaving some beast scratches.

He didn't plan to pick wild fruits at night, firstly, because he didn't want to pit Du Liyuan, and secondly, it was naturally because of this.

After all, safety comes first.

"It's too dangerous to go up the mountain so late, right?"

Lu Dongye muttered, squinting his eyes at the swaying figure on the hillside.

But after a while, he frowned: "It doesn't seem like a villager." ”

He found that the swaying figure was sturdy, not like the old, weak, sick and disabled people in the village.

Got a stranger into the mountains?

In Lu Dongye's mind, a big question mark inevitably floated.
