Qian Rujun stood by the river and could see the trees on the opposite bank. And see it very clearly. At this distance, there is no Yangtze River.

But Qian Rujun knows that this river, from beginning to end, is not considered flat land, and it has a lot of kinetic energy. It is most suitable for generating electricity.

Unfortunately, there are no castles in the vicinity at all.

In terms of power generation, even in later generations, a few households will take a wire to the past, which is actually not in line with the cost.

If it wasn't for the policy that every household had electric lights, it would not have allowed the power company to install electricity regardless of the cost.

Fortunately, the population density is the second highest in the world, and the overall cost is not too high. Because the population is dense enough. The user is worth the length of the line.

Therefore, Qian Rujun felt that shipbuilding was a completely unnecessary behavior.

Even if it is Jinmaicheng technology, it takes a lot of time to build a ship, and in terms of shipbuilding, Qian Rujun did not change a few technical books in later generations except for the advanced technology of the Han Dynasty.

The students of Xuetang Island eat and dress well every day, and the food they eat is nutritious.

There are many unhealthy foods compared to the food that was full of food safety problems in later generations, and this is really the top ingredient.

The food in Qian Rujun's space, unless there is another aura space, otherwise, there is no possibility of surpassing the Qian family's farm.

Qianjia Farm is a natural and organic, the best product.

The students of Xuetang Island, with a moderate amount of exercise every day, plus they are people who practice martial arts, so there is definitely no problem with physical strength.

Qian Rujun remembers that later generations of Chinese had the experience of challenging to cross the Yalu River.

In fact, don't say that Chinese swim over, North Korean women are more interested in swimming.

Swim past to the North Korean nitrate tower, and stare at them with eye eyes and noses.

If you swim over, you should hurry up to find your husband and take advantage of the opportunity to become a spouse to live quickly.

Anyway, on both sides of the Yalu River, there are Koreans, and there is no problem with language and culture.

Even after a long separation, there is still a lot in common.

Even the red stripes of China's winter swimming base used to flutter very close to North Korea.

Of course, Qian Rujun is now in North Korea, but she is not interested in going over to find her husband.

Now, the people who live there are not even Chinese, but more than Fuyu.

I don't know which ethnic group their bloodlines will be mixed with in the future generations.

The Han people are a big mixed race, after coming to the Han Dynasty, where Qian Rujun walked, he has found that the people of this era are more like the Hakka people, Hokkien people, and Cantonese people in later generations.

But the height is still good.

At least the seven-foot man can still be found.

Shows that the bloodline genes are not bad.

Not to mention, this season is not winter, it is the best time to swim in August.

"The distance between the two sides of this river is not too long, we still swim over, if we are afraid of accidents, that is, half of the people swim over first, if there is an accident, the other people are coming down to save. Qian Rujun said.

For Qian Rujun's decision, all the students took it for granted, and did not regard this, the project of bravely crossing the river as a big deal.

Of course, they will carry out the warm-up activities that should be carried out before swimming, and the best warm-up activity is for everyone to dance a "Xuanwu Feihua".

It's a pity that there is no audience at the scene, so you can't see the visual beauty produced by so many people dancing "Xuanwu Feihua" together.

This kind of visual beauty must be able to trigger a lot of ideas, the painter can paint the most beautiful picture, the musician may come up with the most beautiful music, and the martial artist will even come up with new moves.

Of course, Qian Rujun was also among them, so she didn't have time to sigh about the losses that these people would have.

When everyone's body gradually heated up, Qian Rujun asked half of the people to go down to swim first, and the other half of the people, of course, did not stand in a daze, but continued to slowly let their bodies move.

I don't know if it's because of their martial arts practice, their bodies have become a bit cold-blooded, and their blood is not easy to boil.

Even the body usually doesn't sweat much, so in order to make the body sweat, they even "Xuanwu Feihua" danced for a whole hour.

Because this river is not a short 100 meters, Qian Rujun is still more cautious, because there is no record of long swimming before.

Water is much more physically demanding than walking on land.

Even, an ordinary person who does not swim in the water can lose three kilograms of weight after an hour.

How many calories is three kilograms? Qian Rujun didn't dare to calculate, and with the people present, their weight barely reached forty kilograms.

That is, in the early thirties of kilograms, because of the relationship that was not well developed, everyone will not be too tall, but because of the relationship of sufficient nutrition in the later stage of nutrition, everyone will not be too short.

In this era, it is considered to be a beautiful man or a tall beautiful girl.

"Let's go!"

At this time, there was no need for Qian Rujun to postpone, so Qian Rujun jumped into the river first and began to move to the opposite bank.

Of course, before jumping into the river, everyone's body has changed their clothes, otherwise, the original cotton clothes are too absorbent, and the consequences of water absorption are very serious, which will make the body burdened heavily.

Although there is buoyancy in the water, the gravity brought by these clothes after absorbing water is very terrifying.

Even buoyancy sometimes has no way to take these gravity but to sink.

So Qian Rujun asked everyone to enter the space, and gave everyone a fish to change into in their own room.

Originally, being naked ** was probably the best way to swim, and there was no burden, but there were men and women present, and they were all hot boys and girls.

Qian Rujun didn't dare to take this risk.

What's more, she attaches great importance to the privacy of her body, and she doesn't like to let people see her body at all.

The swimming along the way was quite smooth, although the speed was a little slower, but in order to maintain physical strength and good physical condition, Qian Rujun did not particularly sprint forward, but swam forward slowly.

Perhaps it was the first time he swam for such a long time, and Qian Rujun found that his physical strength was really different from before.

The first scene she crossed over was that she fell into the water and swam desperately ashore, at that time, she was thin, weak, and her physical strength was limited, and she could barely swim.

Fortunately, God has eyes, and he didn't go too far from the shore at that time, after all, his father and mother couldn't swim at all.

If you lose your child, you won't throw it too far offshore.

However, when Qian Rujun gradually swam to the middle of the river, she suddenly found that the e-paper book had reacted again.

Qian Rujun hurriedly paid attention to it, it turned out that the e-paper book was interested in a fish here, which means that the e-paper book hoped that Qian Rujun would go fishing.
