After traveling through time, I led the whole village to become rich!

In early August, Xiang Chunhua was ready to go back after playing in Beijing for less than a month. Zhang Hulan bought a lot of things for Xiang Chunhua to take back.

It is the hottest time of the year now. Zhang Hulan told Xiang Chunhua that next time she comes to Beijing, she should either come in spring or autumn, and not rush to come in summer.

Xiang Chunhua hugged Zhang Hulan and said, "Sister, take good care of yourself in Beijing."

"Okay, I'm an adult now, can't I take care of myself? You should leave now. I'll be back for the New Year at the end of the year."

After seeing off Chunhua, Zhang Hulan continued to busy herself with village affairs.

The bitter melon, tomatoes and peppers she planted grew well, but she didn't eat any of them and saved them all for seeds.

All the peppers are the kind of chili peppers. After they turn red, they are dried and the stems are taken out. The pepper skins are taken to the hot pot restaurant. Zhang Hulan plans to bring some back to Daping Village when she returns to the end of the year.

The potatoes she grew were not very good.

Due to the variety and the fact that they were planted late, they were very small and many of them died.

It will be ready for digging in about a month. I will probably be able to harvest a few sacks from the more than one acre of land I planted.

In fact, very small potatoes are especially delicious when you boil them in water, peel them, fry them in oil until golden brown, and then sprinkle them with chili powder.

She also wants to bring some back when she goes back, and she wants to take all the good things home.

Zhang Hulan was walking on the edge of the field wearing a straw hat, and Xie Xiaoman was following behind her wearing a straw hat as well.

Xie Xiaoman also admires Zhang Hulan and feels that she knows everything.

Xie Xiaoman said, "Sir, can the hybrid rice you've developed really yield 700 to 800 kilograms per mu?"

"It's hard to say. If the seeds we cultivate are good, it's not impossible to produce over a thousand kilograms per mu."

"If you can really harvest a thousand catties of rice per mu, then your contribution will be great. I heard that under normal circumstances, one mu of land can only yield two or three hundred catties of rice, and in bad times, one mu can only yield a little over a hundred catties."

Zhang Hulan reached out and stroked the rice ears, saying, "During natural disasters, it's considered a good harvest if we can get over 100 kilograms per mu. During natural disasters, there's basically nothing to harvest, and the people have to rely on digging wild vegetables and chewing tree bark to survive."

Xie Xiaoman sighed, "The common people are indeed suffering. I hope that the hybrid rice cultivated by the adults will be successful, so that the common people can harvest more food every year. With food stored at home, we don't have to worry even if we encounter the occasional natural disaster."

Xie Xiaoman then sighed again and said, "Sir, why do natural disasters happen? How wonderful it would be if there were good weather and good harvests every year? What exactly is going on with these natural disasters?"

Zhang Hulan thought that Xie Xiaoman’s wish would never come true.

Not to mention here, even in her previous life, with such advanced technology, she could not change the climate, and various natural disasters would still occur frequently.

Zhang Hulan said: "Most natural disasters are caused by the climate. Sometimes we have continuous heavy rains and floods, while other places suffer from droughts.

Do you know that the rain that falls in this world is evaporated from the ground into the sky, and then falls down again?

Zhang Hulan pointed to the clouds in the sky and said, "If the water vapor on the ground evaporates to a certain level, it will form dark clouds in the sky and then turn into raindrops to fall down."

Xie Xiaoman asked in confusion, "Sir, I understand that the water on the ground evaporates because of the hot weather, but why does it form clouds and then turn into rain?"

Zhang Hulan asked, "Have you ever boiled water?"

Xie Xiaoman nodded, "It has been burned."

"When the water boils, can you see steam rising?"

Xie Xiaoman nodded.

"When you lift the lid of the pot, can you see a lot of water dripping down from it?"

Xie Xiaoman continued to nod.

"That's it, isn't it? When the water vapor reaches a certain level, it will condense into water again."

Zhang Hulan pointed at the white clouds in the sky again and said, "Look at the white clouds in the sky now. This is because there is less water vapor and the cloud layer is thin. When the water vapor condenses to a certain level, it will turn into dark clouds, and then it will start to rain."

"Oh, I understand. Adults are amazing. They even understand all this." Xie Xiaoman's face was filled with admiration. Then she asked, "What about hail? Why does hail occur in summer?"

"Are you asking a hundred thousand questions?" Zhang Hulan glanced at Xie Xiaoman speechlessly, but still explained, "Because the hail clouds are higher.

The temperature gets lower the higher you go, just like it is cooler on the mountain than at the foot of the mountain.

Sometimes it snows in the mountains, but not below them.

So when some clouds float higher, what falls is not rain."

Xie Xiaoman admired him so much, "Sir, how come you know everything?"

"I didn't expect that Zhang Tunjian also studies climate and the cycles of heaven and earth?"

A voice sounded behind Zhang Hulan and Xie Xiaoman.

Zhang Hulan turned around and saw that it was Qin Bingrong. He saluted quickly and said, "Your humble servant greets Lord Qin."

"Greetings, His Excellency the Prime Minister." Xie Xiaoman also hurriedly bowed.

Qin Bingrong smiled and said, "I didn't mean to eavesdrop just now, please don't blame me, Zhang Tunjian."

"No, no, I'm sorry to have made you laugh, Master Qin."

Qin Bingrong said, "The Ministry of Industry has completed the water pump. I'm here to deliver it to you."

"Master Qin, please just have someone notify me. How dare I trouble you to deliver it in person?"

"No problem, I have nothing to do, so I came to take a look."

Qin Bingrong pointed to the office room and said, "Everything is placed over there. Zhang Tunjian, go check it out."

Zhang Hulan then went with Qin Bingrong to see the finished water press, as now was the time when it was needed.

The water press made was similar to the one Zhang Hulan had used before, and the pipes connecting the water press were also made, which was made by breaking through the bamboo joints.

Zhang Hulan took a water pump to the well and asked Xie Bangwen to arrange someone to find two stone slabs to install and fix the water pump.

Pour some water in it and then shake the lever.

There was a "creaking" sound for a while, and then water was pressed up.

Zhang Hulan asked Xie Bangwen to try it out. "Master Xie, feel it and see if it's easy to draw water like this."

Xie Bangwen tried it and found that it didn't require much effort at all, and large amounts of water were pumped up.

Then he let the people who were working try it, and after trying it, they all said it was good.

"This thing is good! This thing is good! If I use this thing to draw water, I can irrigate 20 mu of land in a day."

Qin Bingrong also admired Zhang Hulan. He wondered how she came up with the idea of ​​fetching water in this way?

Zhang Hulan asked, "Master Qin, how many have the Ministry of Works produced so far?"

“We’ve made ten so far.”

"Are the others in the Ministry of Works? Then I'll have someone get them."

Qin Bingrong coughed dryly and said, "Ahem, this is the only one left. The rest have been divided among the emperor and several ministers."

Uh……

Zhang Hulan was speechless.

Qin Bingrong said, "Minister Zhai has already ordered the Ministry of Works to rush the production, and it will be produced in large quantities in a few days."

What can Zhang Hulan say? She can only wait.
