The wind and rain are rustling, the wind and cold rain are rustling.

The avenues in Chang'an City are all dirt roads, and low-lying sections of roads accumulate into pools, and other roads are muddy, and horses are trapped in mud. In this weather, the more cars and horses you walk on the road, the muddy roads are harder to go.

The emperor had to issue an order to stop courting during holidays.

Even Chongxian Pavilion has to go on holidays without classes.

As the imperial capital of the world, Chang'an City has become a mud city due to the continuous rain. This is something Qin Lang never thought of. How could this happen to the towering Chang'an and the glorious imperial capital?

Ma Zhou, who has served as the censor of the palace, submitted a request to dig sand from a river near Chang'an to transport it to the city, and lay a sand embankment corridor on the sixth street in Chang'an for vehicles and horses to drive.

Qin Lang rode the leopard head and walked on the newly paved sand embankment corridor. Finally, he didn't have to be splashed by the mud and water like he did a few days ago.

When I came to the Eastern Palace and removed the poncho, my clothes were still wet half.

When Li Shimin saw Qin Lang, he said, "This autumn rain came in time. The wheat that had just been planted in the field has water. The locust eggs you mentioned will also be drowned by this rain, right?"

Qin Lang was not so optimistic. The rain had been falling for many days, but it was not heavy. Chang'an became a mud city, but the water level in the canals in Chang'an City did not rise much, which means that the precipitation was actually not high. Then the exposed low-lying areas such as the riverbed and lake shores in Guanzhong would not be flooded by water, and locust eggs would not be drowned in large quantities.

"I hope there will be two more heavy rains in God." Qin Lang could only say this.

"Let's go and see how your eggs hatch." Li Shimin said.

These days, Qin Lang came to the East Palace every day, not to discuss military and political affairs, but mainly to come to the greenhouse to hatch chickens. That day, he spent countless saliva in Xiande Hall, and barely calmed down Li Shimin's anger. He taught the prince's hatching chicken experiment to cultivate the prince's ability to observe and learn, and to let the prince understand various high-level purposes of people's livelihood.

He also said that the prince was participating in an important plan to fight locusts and disaster relief.

The final result was that after the arrival of Princess Changle Li Lizhi, the conversation was wrong.

Li Lizhi insisted on doing this experiment, but in the end, Li Shimin actually asked Qin Lang to build a greenhouse in the East Palace. He wanted to participate in this important experiment in person to see if it was really as mysterious as Qin Lang said.

The king and his ministers first went to Lizheng Hall to call Princess Changle, and then went to the newly built greenhouse.

When I opened the curtain of the greenhouse, a wave of heat suddenly rushed towards me.

Qin Lang felt that the room temperature should be thirty-seven or eight degrees, which seemed as hot as summer in this cool autumn rainy season.

There are warm kangs in the greenhouse, which are completely built according to Qin Lang's requirements. They are covered with thick quilts and thick wheat straw under the quilt.

Lift a corner of the quilt and spread the eggs one by one on the wheatgrass.

Qin Lang reached out and touched the egg, felt the temperature, and touched the egg lightly in his palm, which was very warm.

Li Shimin also reached out to follow the example and touched the feeling.

"I have never heard of hatching chickens without hens. Can this really happen?"

Li Lizhi looked around and looked at the neatly tidy eggs very happily. She followed suit and touched them all, but she didn't care about the heat in the warm room.

Qin Lang said, "As long as the heat remains unchanged, chickens will break out of their shells in about twenty days. Of course, in addition to burning the kang to maintain this heat, every two hours, you have to turn these eggs over to allow them to heat evenly."

"It usually takes about twenty-eight days to hatch chicks, but you can do it for twenty days?"

"The most important thing for hatching chicks is this temperature. Using this warm kang, quilt wheatgrass simulates the temperature of the old hen. If the temperature is suitable, the eggs will naturally break out of the shell. It is shorter than that of the old hens because the heat of this warm kang in the warm kang is more stable and continuous. After all, hens always have to leave the nest to eat and drink water."

Li Lizhi's face was flushed soon and she was even sweating slightly, but she was still unwilling to leave.

Qin Lang had left a special place for her in a corner of the kang, covering her with twenty eggs under the quilt, and there were marks drawn by Li Zhi. Now she was staring at these eggs, and even named them eggs of different sizes, shapes, and colors.

The one with red shells is called Xiaohong, the one with white pots is called Xiaobai, and the one with poops is called Xiaomazi...

Although Li Shimin always said he didn't believe it, Qin Lang knew that he had actually believed Qin Lang in his heart when he saw that he was so diligent every day.

In addition, the warm kang made by Qin Lang to hatch chickens was also attracted by Li Shimin, and he had long been thinking about other uses of the warm room.

Although this thing is not needed in the palace, because there is no shortage of charcoal fire in the palace in winter, and there is also a fire wall in the emperor's bedroom, with a flue inside to keep heating.

But it will undoubtedly be very useful in other aspects.

For example, if there is such a warm kang in the military city and garrison on the northern border, it will definitely help the soldiers survive the cold winter better.

Even ordinary people will be very comfortable to sleep on such a warm kang in winter. No need to worry about sudden extreme cold falling from the sky, and many people will freeze to death.

Today, Li Lizhi named another egg that was a little small, called him Xiaoxiao.

"Sanlang, can Xiaoxiao separate male and female after hatching?"

"Of course this is OK."

Li Shimin looked suspicious and thought Qin Lang was bragging, how could such a small chicken divide the male and female?

Qin Lang smiled and said that after the chicks hatched, they had to go through separates and leave more hens, so that many laying hens can be obtained. As for the small roosters, they can be placed together and raised for short-term breeding, or castrated after they are slightly larger, so that they can become fast-growing broilers.

"How to divide it?"

Qin Lang raised his index finger.

"Press this fingertip on the butt of the little cock, and the little hen will have a hard bone point when touched, but the little hen will not have it."

Li Shimin stretched out his index finger, which was covered with old skin calluses. "Can you feel it?"

"Your Majesty has a hard skin on his fingertips, which is not easy to feel. You can grind off the hard skin on the grinding stones so that you can be sensitive."

After leaving the greenhouse, Qin Lang told Li Shimin.

"Your Majesty, this is the price of grain collected by the Punishment Department."

Li Shimin took it, looked at it for a few times, and frowned.

Since its establishment, the Zhenfu Department has developed rapidly. It has set up dispatched agencies in the prefectures of Yang, You, Jing, Yi, Guang, An, Luo and Liang, and has stationed personnel in various prefectures around the world. It not only monitors officials from all over the country, but also collects various intelligence.

Qin Lang had previously issued an order to the lower level in accordance with Li Shimin's order, asking them to focus on collecting grain prices in various places and price changes in various important livelihood commodities.

This information was summarized in several major branches and then sent to Chang'an Punishment envoy through the post station.

"The grain price in Chang'an exceeded 200 coins ten days ago, and Luoyang and Taiyuan also broke through this line."

Although the imperial court has taken over the grain from the charity warehouses in various places, this amount of grain is nothing at all, and the food crisis has become increasingly serious.

The imperial court transported hundreds of thousands of stones of grain from Shandong, Jianghuai and other places to Beijing every year, but now it is far from enough.

"Due to the limitation of the canal transport capacity, the grain transport capacity transported to Guanzhong has reached its limit and cannot be further improved. Soon there is no grain to transport in Shandong and other places."

Li Shimin frowned.

The food gap is very large.

"The prime ministers have already made a proposal to ask me to issue an order to allow the people to even encourage and mobilize the people to start leaving the customs and give food to Shandong and south of the mountain." Li Shimin sighed.

The so-called "going to eat food after leaving the customs means letting the people flee to famine and beg for food. This kind of thing actually happened many times during the Sui Dynasty. At that time, Yang Jian took all the officials and the people out of the capital to Luoyang for food after leaving the capital more than once.

At that time, there was a famine in Guanzhong. Although there was grain reserve in the Jianghuai area at that time, due to the capacity of grain transportation, it was impossible to import more grain into Guanzhong, so in the end, I had to go to Shandong.

After all, when the previous dynasty was prosperous, Chang'an alone had a population of one million. So many people in the capital consumed a huge amount, but it was mainly consumed by imports. Since the grain could not be transported, people would go find food.

But now the problem is that Henan and Shandong have no food either.

Li Shimin did not immediately agree to let the people go out of customs and took food, considering that this would cause unstable factors, it was not long before he ascended the throne and came to power, and he was afraid that someone would use it to make trouble.

Secondly, he thought it was not that serious.

Now that Qin Lang handed him the complaint about the price of grain in various places, Li Shimin realized that the matter might be more serious than he judged. From the fact that the food prices in various places are generally soaring, it can be seen that there are food shortages in various places.

"Your Majesty, what I am most worried about is the autumn locust this year. According to the local prefectures and counties investigated by the Ministry of Justice, this year, not only in Guanyou, Longyou, Hexi, Hedong, Shandong, and Henan, large-scale autumn locusts may break out, and even in Shannan and Huainan areas, locust plagues may occur."

Qin Lang's words made Li Shimin frown even tighter.

Qin Lang reminded him time and time again that there would be locust plagues, but according to traditional judgment, there was no such argument.

"Your Majesty, there will be locusts after a severe drought, and there will be famine after a severe drought. There will be plague after a severe drought. If you cannot make a judgment in advance and do a good job in prevention, you will really be unable to turn things around when the time comes."

Li Shimin stared at Qin Lang with a fierce look, "Then do you have any good suggestions?"

"Your Majesty, before the disaster comes, you must protect the people. Wherever there is food, let the people go, and plan in advance. You must not be in chaos. Officials must arrange it and send people to receive it along the way. For example, more than 20 counties in Yongzhou can be arranged to go to Shannan. A county in Yongzhou can be arranged to go to Shannan to a prefecture in Shannan. The victims of disasters in a county in Yongzhou will be arranged to go to Shannan to be responsible for the counter-attack. The court mobilized and organized the food to go out of customs and the officials will lead the team to the place behind Shannan to be responsible for the arrangements."

"When the disaster is not serious, transferring the people who have no food or don't have much food at home is given priority, so as to reduce the pressure in the city."

······

Qin Lang also agreed with the prime ministers' proposal to release the people from customs and take food, but they cannot be unorganized and allow the people to flee to famine and beg for food. They must be organized so that they will not be in chaos and will not evolve into large-scale hungry refugees.

Moreover, his out-of-virtue was given priority for the poor, rather than when the famine was serious, the emperor led all officials, nobles and powerful people to run away.

Through the big data comparison of the Zhenfu Department, corresponding counterpart temporary relocation and disaster relief plan was formulated, instead of the countless hungry people being rushed out of the customs and turning into a large army of hungry people like locusts, sweeping along the way, sweeping away the originally not serious areas into disaster areas, and turning other people into hungry people.
