"Daddy!"

Xue Lang came back from outside and immediately received a warm hug and kiss from the little water slave baby.

Xue Lang hugged his daughter with a smile, kissed him, and asked with a smile: "Is the water slave well-behaved today?" ”

"Good! My brother is also good! ”

That little look made Xue Lang kiss her again, and hugged her in.

On the first day of August in the ninth year of Wude, the sage Li Yuan worshiped his ancestors in the Taimiao, sacrificed to the sky in the mound, and held the crown prince's canonization ceremony. Ten days later, the sage Li Yuanchan was located in the prince and lived in Daxing Palace. Li Shimin ascended the throne as the emperor, and the next month the eldest grandson of the former crown princess was established as the queen, and the eldest son Chengqian was appointed as the crown prince, and the Yuan Zhenguan was changed.

In the same year, because he left his post without permission, he took the post of Admiral of the Commander of the Naval Division of the Eldest Princess of Pingyang, Anguo, and was fined for three years; Take the post of Xue Lang, the Duke of Rui, as the agricultural official, and be fined for one year and go to work! transferred to Suzhou Governor Jiang Lin to take over the post of Admiral of the Navy; In the spring of the first year of Zhenguan, Xue Lang and Princess Pingyang's nickname Tannu, the eldest son of the big name Xue Jingpu was born, and Xue Lang was idle at home and had never served in the court.

Xue Lang went out to check the situation of the farm before returning.

The ninth year of Wude was a warm winter, the summer was hot, the rain was scarce, and the Yellow River basin was somewhat dry, including Guanzhong, and the grain yield was also reduced due to the lack of rainfall. In the first year of Zhenguan, it was also a warm winter, and the water level on the banks of the Weishui River dropped more than in previous years, and if the rainy season came next year, the rain was still scarce, but I was afraid that the drought would continue.

Xue Lang went out to take a look, and many waterwheels have been built around Chang'an City, because of the developed water conservancy facilities, it can be expected that the grain production will be reduced, but it is not to the point of no harvest.

However, Xue Lang was worried about another thing, which is also recorded in history. In order to have something to say, he also deliberately went to the field to squat for several days, and after a careful inspection, he could already be sure.

Princess Pingyang saw Xue Lang frowning, with a thoughtful expression, put Tan Nu in the cradle, and asked, "Why are you so worried?" ”

Xue Lang said: "Jianling, have you heard a word?" ”

"What?"

"There will be locusts after a long drought!"

Even Princess Pingyang's expression became solemn: "You mean, there may be a locust plague in the coming year?" ”

Xue Lang nodded, sent someone to carry the soil he dug back from the field to the eaves of the porch, and beckoned to Princess Pingyang, who immediately came out and watched him pick up the clods of soil: "See?" These are locust eggs! ”

Princess Pingyang glanced at it, her expression remained unchanged, and she was only slightly puzzled: "This is a locust egg?" Seriously? I've heard people say that locusts are made up of fish and shrimp eggs, shouldn't they be in the water? Why in the clods? ”

Xue Lang was a little dumbfounded for a moment! His face was full of incredulity: "My Highness, this locust belongs to the insect family, this fish and shrimp belong to the animal family, the fish is a notochord, the shrimp is an arthropod, and the locust is a different species." This locust is made of fish and shrimp eggs...... Who is so misleading and indiscriminate? ”

Princess Pingyang's eyes wandered twice, and she asked quietly, "What about insects, notochords, and arthropods?" What's the difference? ”

Xue Lang immediately explained: "This is a biological classification of species. I'll tell you ......"

Xue Lang slowly explained to her what biology is, what classification is, and what is the standard. Princess Pingyang quietly exhaled as she listened.

After listening, he looked at the insect eggs in the clod of soil carefully, and his expression became solemn: "There are so many insect eggs!" ”

A basket of clods of soil can be picked up with several rows of locust eggs. This is just a basket of soil, if it is in each acre of field, such a clod of soil does not need much, only one-third...... Princess Pingyang didn't dare to think about it, and suddenly felt her scalp tingle.

Xue Lang patted the soil on his hands, cleaned his hands with the water brought by his subordinates, and said, "You come with me!" ”

Pulled Princess Pingyang to the ear room, and when she got to the ear room, she pushed the door open, and the house was full of baskets, and the baskets were full of clods. Xue Lang squatted down, began to pull clods, raised his head and called Princess Pingyang, and said, "This is what I dug last year, come and see!" ”

The clods of soil were dry and the eggs inside were shriveled, but the eggs could still be seen. Xue Lang said: "There was little rain last year, so I was afraid of a locust plague, so I paid special attention to it. The clods of earth in this house were collected by me from above your farm, from the fields near our farm, and there were not many eggs in it. So, last year I just had the soil darker, burned and sprinkled with lime powder. Not to mention the continuous drought this year, the temperature is also warmer, I paid attention, and sure enough, there are more eggs in the soil than last year, and this density is ...... There will be a plague of locusts in the coming year! ”

Princess Pingyang's expression became serious: "This matter ...... Can you be sure? ”

Xue Lang patted the soil on his hand and said, "** Not far from ten!" You've also seen the eggs in the clods, and with this year's density, when the eggs hatch next spring, it's almost certain that locust plagues will occur! ”

Princess Pingyang thought a lot in an instant, smiled bitterly, and said, "So...... Do you want to do it? ”

Xue Lang said without hesitation: "Since I have the worm eggs in the clod of soil to testify, it is not empty words, and the fallacies confuse the public, so I naturally report to the saint." ”

Princess Pingyang sighed faintly and said: "Now is the first year of Zhenguan, and when it comes to the beginning of spring, it is only the second year of Zhenguan." The saint has only been on the throne for two years, and not to mention the drought for many years, it seems that there will be another locust plague......"

Although the words are not finished, the meaning is clear. Originally, Erlang's throne was not rightly named, but after he ascended the throne, he was so unsatisfactory, and in terms of ancient feudal superstition, I am afraid that it will be said that it will be said to be a curse.

Princess Pingyang replied: "Youyang, you are a public report, if you are framed by the villain because of this, Ruo Erlang will punish you for all kinds of considerations...... When? ”

Xue Lang said resolutely: "You can't pretend not to know!" If we can prevent it from happening, the locust plague is not terrible, but if it is allowed to happen, it will be a matter of disregard for human life, and my conscience is disturbed. What's more, natural disasters are natural disasters, and the causes of natural disasters are complex, so what does it have to do with people? This natural disaster involves the virtue of those in power, and I think it is just playing the piano indiscriminately! ”

This loud look, Princess Pingyang's heart warmed, this is her young yang. After smiling slightly, he asked, "You just said that if it is prevented, the locust plague is not terrible...... But is there a solution? If there is, write it, and submit it together tomorrow, so that it is the best, so that no villain will frame you and confuse the public. “

Xue Lang nodded.

For more than a year, he has been idle at home, and he does not go to court except for feasting on festivals and saints to invite princes and ministers. However, there are more times to enter the palace, either with Princess Pingyang, or with a water slave, or he is alone, all of them go to the palace to accompany the old father-in-law, pulling the old father-in-law together, and the two of them are either fishing and playing chess, or painting and chanting...... Of course, it was Xue Lang who painted, and Comrade Li Yuan, the old man, who recited poetry.

Although Comrade Lao Li's level of poetry writing is not good, it is much better than his stupid son-in-law. As for the question of who sings the poem, after trying to listen to Xue Lang sing once, Comrade Lao Li came to his senses, and sang it himself every time he wrote...... Lao Li said that he wanted to live a few more years.

Just look at the refreshing one
