God-level prince of the Tang Dynasty

Chapter 600

Li Chengqian almost had to run to reach the Taiji Palace. At this time, all civil and military officials were already in the palace, while Li Shimin on the dragon chair was frowning.

Clearly, this time it was a big deal.

"His Royal Highness is here!"

Until the little yellow gate shouted.

All the people turned their eyes to the outside, and they focused all their eyes on Li Chengqian alone.

Li Chengqian received more attention than Li Shimin, but Li Shimin didn't have time to pay too much attention now.

When he saw Li Chengqian coming, he waved and said, "Gao Ming, come here, come here!"

Li Chengqian was puzzled, stepped forward and then asked quickly: "Your Majesty, I heard that something important has happened, do you know what it is?"

He was still confused.

Li Shimin was dumbfounded.

"No one told you?"

Xiao Huangmen didn't say anything!How does he know?

"Yes! My son only heard that something important happened, but he didn't know why."

At this time, Du Ruhui came out and said, "His Royal Highness, it is like this. This morning, a pigeon sent a message from Tongzhou to Chang'an City. There was a plague of locusts in Tongzhou!"

Tongzhou is more than 500 miles south of Chang'an City, which is not a small area.

There are few people living between Tongzhou and Chang'an City, so even if it is eaten up by locusts there, people don't feel bad. Even if they want to resist, it is impossible. When people arrive, the locusts will fly away.In fact, what people are more afraid of is whether Chang'an City will be affected by the plague of locusts.

After Du Ruhui's words came out, everyone's heart was still heavy.

"Where is the plague of locusts spreading?"

Li Chengqian asked a crucial question.

"The plague of locusts is very likely to spread to the north! Heading towards Chang'an!"

Tongzhou is more than 500 miles away from the west of Chang'an City in a straight line.The flying speed of the locusts is 10km/hour. In fact, they ate all the way, so the speed is not so fast. It took about three days to reach Chang'an City.The crops outside Chang'an City are growing very well. The emerging crops planted during this period are extremely attractive to locusts, so [-]% of them will come to Chang'an City.

Locust swarms have caused unrest throughout history.All the locusts in the world alone can cover 20% of the earth's land area, eat up to 200 tons of vegetation every day, and affect the livelihood of 10% of the world's population.

Pre-Qin ancient books such as "The Book of Songs" often refer to locusts as katydids (katydids are the general name of locusts, including katydids) or scorpions, and scorpions are nymphs of locusts (insect larvae with incomplete metamorphosis are called nymphs).After the Warring States period, it was often called locust.Both locusts and gnats damage crops.The earliest record of locust plagues in ancient books is "Spring and Autumn", which records the 15th year of Lu Xuangong ([-] BC): "At the beginning of taxation, winter, locusts grow."

The earliest record of locusts is "Lu's Spring and Autumn Annals Mengxia Ji Fourth": "When the spring order...the locusts will be defeated."

And the same book "Shen Shi Pian": "...the hemp that gets the time... if this is the case, it is not a locust."About after the Song Dynasty, the chrysalis was renamed "蝻", collectively known as locust gnats, and it is still used today.

Xu Guangqi of the Ming Dynasty’s "Nongzheng Quanshu · Eliminating Locusts" counted the number of locust plagues in the Spring and Autumn Period (111-[-] BC), and pointed out that there were [-] locust plagues in the Spring and Autumn Period ([-] years), and the monthly distribution is as follows:

月份（农历）02|03|04|05|06|07|08|09|10|11|12
发生蝗灾次数02|03|19|20|31|20|12|01|00|00|03
A plague of locusts means that billions of locusts cross the border at every turn, destroying crops wherever they go, and it will be a great blow to the agriculture of Chang'an City.If it is not extinguished in time, it will be another disaster for the area north of Chang'an City.

No one wants to see Chang'an's crops destroyed.Once agriculture is destroyed, all kinds of unstable factors will be completely magnified, which is completely unfavorable to the rule of Datang. If such internal and external troubles will make Li Shimin burnt out.

According to historical records, the plague of locusts should have occurred in June at this time. Could it be earlier?

Or is it a test given to him by God?

"When did the carrier pigeon come?"

"An hour ago."

As soon as Li Chengqian heard what Du Ruhui said, he murmured: "The flying speed of the carrier pigeon is about [-] kilometers per hour, so this letter was sent about two hours ago, so we still have nearly three days left." Time to prepare!"

Li Chengqian didn't know, his words had already been heard, someone asked: "His Royal Highness, what three days?"

How do you know, how did he calculate it, three days?
Even Li Shimin felt a little ridiculous.

"Gao Ming, you know that, and you're here in three days?"

Li Chengqian said straight: "Your Majesty, this is the arrival time of the locusts calculated by my son."

Everyone was in an uproar, how did this work out?

"Calculated based on speed and distance."

Li Chengqian had no choice but to tell all about how he calculated, and what he said was so mysterious that everyone was a little puzzled.

But the overall key is not how to calculate it!

At this time, Liu Hongji said: "No matter when we come, we must make some decisions, right? We shouldn't waste time on this, right?"

"Duke Kui! The so-called knowing the enemy and knowing the enemy is invincible. If you want to make a decision, shouldn't you know when the enemy is coming? What preparations should we make! Don't you think so?"

Li Chengqian retorted face to face, provoking everyone to agree.

"His Royal Highness is right, that's it! If we don't know when the locust plague will come, how can we prepare?"

"That's right, that's it!"

But someone said very negatively: "This is a natural disaster! I'm afraid it can't be solved!"

For this kind of disaster, the ancients were helpless.

Liu Hongji said coldly: "It seems that His Royal Highness has made a decision and has a plan! I want to hear what His Royal Highness's plan is!"

All civil and military officials were helpless, and Liu Hongji said such an invitation, obviously digging a hole for Li Chengqian to jump.

Cheng Yaojin said: "There is nothing we can do about this disaster, Duke Kui, why don't you think of a way, and ask His Royal Highness to deal with it? It's really incompetent!"

"The talents of His Highness the Crown Prince are well known in the world. Generally speaking, when we have no other choice, it is always right to seek His Highness the Crown Prince."

Liu Hongji tried his best to put a high hat on Li Chengqian.It was refreshing to hear.

Li Chengqian liked the feeling of being flattered.

So he said: "Duke Kui is right, you have foresight! This king has a way!"

When his words came out, everyone fell silent, especially Li Shimin, the expression on his face relaxed a little, you know he was very depressed just now.

Liu Hongji sneered unexpectedly, and then said: "I don't know what the Crown Prince is going to do?"

Li Chengqian really jumped into the pit, now someone is happy.

Some people followed Liu Hongji's words and asked: "Yes, what is the solution? Tell me and listen!"
