Not long after Han Qi returned to Bianjing, Bao Zheng also returned to Bianjing.

After Bao Zheng came back, he was appointed Zhijianyuan and Prince Taifu.He is familiar with the laws of the Song Dynasty and specially taught Zhao Yang the laws of the Song Dynasty.

Sure enough, Bao Zheng did not disappoint Zhao Yang, and he also agreed to support Zhao Yang in recovering the sixteen prefectures of Yanyun.

With the support of Han Qi and Bao Zheng, Zhao Yang has some confidence in his heart.

During this period of time, all the war horses that Zhao Yang asked the people of Huangcheng Division to buy were safely and smoothly sent back to Bianjing.

Before, Song Renzong gave Zhao Yang the Beishan outside Bianjing city to raise war horses.Once the war horse was bought back, it was sent directly to Beishan for breeding.

The people of Huangcheng Division specially sent people who were good at raising and training horses in Yanbei area to Bianjing.

Although the Yanbei area was occupied by the Liao State, the people in the Yanbei area never recognized that they were from the Liao State. They thought they were from the Song Dynasty.

Now that they have the opportunity to play for Song Dynasty, the people in Yanbei area are naturally very happy.

Zhao Yang deliberately went to Beishan to have a look, and was very satisfied with the war horse he bought.He also chose a war horse for himself.

In his previous life, Zhao Yang often went to the equestrian club to ride horses with his friends, and he also participated in equestrian competitions.He has a knack for riding and training horses.

Zhao Yang brought back some war horses from Beishan to raise in the palace, and sent some to the imperial guards in the palace.There are more than a dozen war horses left, and he and Cao Xu practice riding on weekdays.

In fact, there are also horses in the palace, but they are not as good as the war horses in Yanbei area.

In the afternoon, Zhao Yang took Cao Xu to the training ground to practice riding and shooting after finishing his class with Ouyang Xiu.

When they arrived, Empress Cao was riding a horse.

During this period, Empress Cao often came to the training ground to ride horses.Sometimes, she would accompany Zhao Yang and the others to train together.

Cao's children can ride horses.Empress Cao learned to ride a horse when she was about the same age as Zhao Yang.

The practice didn't end until the beginning of the unitary hour.Empress Cao took Zhao Yang and the others back to Kunning Palace.

Ever since Zhao Yang bought the war horse back, Empress Cao would go to the training ground for a jog every day, and her mood naturally became very good.

If Empress Cao was a man, she would definitely be a brave general. Unfortunately, she is the empress of the Song Dynasty and has no chance to go to the battlefield.

"It's been a long time since I played polo." Empress Cao thought for a while and said, "How about holding a polo tournament in a while?"

When Cao Xu heard that a polo match was going to be held, his face lit up immediately, and he nodded repeatedly and said, "Okay, okay."

"Ma'am, you still don't want to hold a polo tournament for the time being." Zhao Yang also wanted to play polo, but now is not the time, "Something happened in Jiangnan, and the ministers will participate in your polo tournament now."

When Empress Cao heard this, she immediately frowned and asked, "What happened to Jiangnan?"

"During this period of time, it has been raining heavily on the Jiangnan side, and the water level of the river has been rising. If the river dam had not been reinforced and thickened some time ago, I am afraid that many places in the Jiangnan side would be flooded." Before that, Zhao Yang had always hoped that I thought about it, but it turned out that his worries were right.Fortunately, Jiangnan made preparations in advance.

Empress Cao nodded and said, "Okay, the polo match will not be held for the time being." After finishing speaking, she asked with concern, "The water level in the south of the Yangtze River has risen, have you taken any countermeasures?"

"Food and medicinal materials have already been moved to a safe place." Zhao Yang frowned slightly, and said with a dignified expression, "Judging from the current heavy rain, the dams on the Jiangnan side may not last long. Dad has already ordered, Let the people in the south of the Yangtze River be properly evacuated." Although the embankment on the south side of the river is reinforced with cement, the water level will grow higher and higher, and sooner or later it will cross the embankment. Once the water level exceeds the embankment, it will flood the villages and rice fields.

Empress Cao breathed a sigh of relief when she heard this: "That's good."

"I hope the heavy rain on the Jiangnan side can stop." Zhao Yang said so, but he knew in his heart that the heavy rain on the Jiangnan side would not stop for a while.

"It would be great if the heavy rain in the south of the Yangtze River could be transferred to Bianjing." During this time, the weather in Bianjing was getting hotter and hotter, and it hadn't rained yet.Even if it rains, it is still drizzle, not cool at all.

Before entering the summer, the city of Bianjing had several heavy rains in a row, which filled the reservoir with water and solved the irrigation situation of the rice fields. Otherwise, the rice fields in Bianjing would be very dry this year.

"Let's have dinner."

The weather was hot, so Zhao Yang asked the cook in the small kitchen of Kunning Palace to get out the cold dishes and stewed dishes of the later generations, otherwise the greasy dishes in summer would really be unbearable.

After dinner and talking to Empress Cao for a while, Zhao Yang and the others returned to the East Palace.

Back in the East Palace, Zhao Yang and Cao Xu were busy studying.

Although there is no electric fan or air conditioner, but there are ice cubes to cool down, Zhao Yang and the others are not hot when they are reading and studying, and they are covered with sweat.

Ice cubes are stored in the palace every year for use in the coming summer.However, even so, ice cubes cannot be used indiscriminately, and must be used by planners.That is to say, each palace uses a certain amount of ice.If the ice cubes used in one day exceed the budget, it is useless.

Seeing that using ice cubes requires careful planning, Zhao Yang used saltpeter to make ice.

After successfully making ice with saltpeter, you can use ice cubes to cool down at will, and you don't need to use it any more.

Zhao Yang also promoted ice-making with saltpeter to the common people, so that ordinary people can also afford ice cubes.

Before he used saltpeter to make ice, ice was very expensive, except for the palace and the rich and powerful who could afford it, ordinary people could not afford it.Now he uses saltpeter to make ice, making ice less rare in summer, and the price will naturally drop.Furthermore, making ice with saltpeter is also very simple, as long as you have saltpeter at home, you can make ice.

The emergence of saltpeter ice made the common people's life much easier in summer.Not only that, the common people also made a lot of delicacies with ice.

At this time, Yuan Song came in with two bowls of smoothies.

When Cao Xu saw this, he immediately dropped the book in his hand and rushed towards Bingsha.

“Smoothies I love.”

The smoothies made by the royal chef in the palace are very delicious, and Zhao Yang and Cao Xu can eat several bowls in a row.However, for the sake of their stomachs, they can only eat two bowls a day.

At the same time, in Taixue, Su Shi and the others were also reading books seriously.They don't have smoothies, though, but ice cubes to cool them down.

Since Zhao Yang used saltpeter to make ice, there was also ice in Taixue, and ice cubes were distributed to the students for them to cool down.In the past, Taixue would not distribute ice cubes to students, because Taixue did not have ice.Now, with ice cubes, the gentlemen and students in Taixue can sleep well at night.

After reading for a while, Su Shi and Su Zhe stood up and moved their bodies.

Su Zhe touched the ice cube with his hand, and the coolness from his palm made him groan comfortably.

"It's really cool." In fact, the conditions of the Su family are also good, but they are not good enough to store ice cubes, so their family does not need ice in summer.I didn't expect them to go to Taixue, and they could actually use the ice. "Brother, His Highness the Crown Prince is so smart that he thought of using saltpeter to make ice."

Su Shi said: "His Royal Highness is a genius."

"Thanks to the blessing of His Royal Highness, we can sleep well at night." When I was at home, it was very hot every summer. When I went to bed at night, I was often hot and sweaty, and I was often woken up by the heat. I couldn't sleep at all. sleep well.Now with ice, they can sleep soundly at night. "Brother, it's late, let's sleep."

"it is good."

Shen Kuo in the next room was still reading the latest issue of Sun Bookstore's magazine.In this issue of the magazine, the principle of making ice with saltpeter is explained in detail.

Shen Kuo watched with relish, and at the same time exclaimed in his heart that it was amazing, who would have thought that saltpeter could make ice.

In fact, saltpeter has many functions, and ice making is just one of them.Many people also like to use saltpeter to make elixirs, and saltpeter can also make fireworks.However, the use of saltpeter to make ice was something that no one had thought of.

Just tonight, there was another torrential rain on the south side of the Yangtze River, and the rumbling thunder made the ground tremble.Lightning violently split the night sky in two.

Overnight, the river overflowed its dikes, washing away villages and rice fields.

Fortunately, they were well prepared, and the common people moved to a safe place on high ground, and their lives were not in danger for the time being.

When the news of the flood in Jiangnan reached Bianjing, more than half of the towns and villages in the entire Jiangnan area were destroyed by the flood.

Song Renzong was worried about the situation in Jiangnan, so he specially sent people to Jiangnan to see what the situation was like there.

After the flood, the heavy rain in the south of the Yangtze River still hasn't stopped, and more and more towns and villages have been affected.The heavy rain didn't stop until two-thirds of the place was submerged.

Although there was a flood in the south of the Yangtze River, the casualties of ordinary people were not serious because of the precautions and preparations made in advance.Furthermore, the food and medicinal materials are well protected, and there will be no famine in the south of the Yangtze River for the time being.

Song Renzong sent many people to Jiangnan for disaster relief, and at the same time brought a lot of food, medicinal materials, and clothing.

Although the flood destroyed many places, there was enough food, and the common people felt at ease, and there was no panic.After the flood was over, the common people and the government worked together to restore the places destroyed by the flood.

After the flood is over, there will definitely be a plague, which is also expected by Zhao Yang.

Song Renzong sent an imperial physician to support him.In addition, there are enough medicinal materials, and the plague in the south of the Yangtze River has been well controlled without spilling over to other places.

Before autumn, Jiangnan was finally tidied up.The imperial court sent a lot of cement to repair the dams, roads and houses destroyed by the flood.

The flood in the south of the Yangtze River this time was very serious, but because of the precautions taken in advance, the casualties were not very serious.For this reason, the people in Jiangnan are very grateful to Song Renzong and His Royal Highness the Prince.

If it weren't for the officials and His Royal Highness to make them prepare in advance, there would definitely be famine and plague in the south of the Yangtze River.At that time, it will also affect other places.

Because of this, the crown prince Zhao Yang's reputation in the eyes of the common people is getting better and better.

Before, the people in the south of the Yangtze River built the Longevity Temple for Zhao Yang, but it was destroyed by the flood.After the flood was over, the people in the south of the Yangtze River built the Longevity Temple for him again.
