God-level prince of the Tang Dynasty

The further you go, the higher the point reward, and this time it will directly start at [-] points.Your own points will also be larger.

Going back to the currency, at this time, the Tang Dynasty used the most copper coins. This kind of coin is very heavy, and a sling of money weighs several catties. If there is a large amount, I may have to use a horse-drawn cart to pull it. It is also inconvenient to store. , if there are banknotes at this time, the convenience will be greatly improved, and the economic efficiency will naturally increase.

Therefore, Li Chengqian also thought about how to implement his own monetary policy!

In fact, as long as he followed the example of the gourd and carried out reforms according to the practices of his time, basically there would be no major problems.Because all countries in that era were like this, and they didn't see bad things.

Okay, that's it. Let's discuss it with Li Shimin tomorrow. If this economic task is put beforehand, he may not be able to complete it. Why?Because everything is not ready, just take paper and printing, these two points alone are enough for him.

It is different now, the current Datang has already made preparations in this regard, the only thing left is the implementation of the policy.Of course, there will be many obstacles, but he is not afraid. He even has the confidence to complete the task after accepting it!Time or something, nothing, big deal and so on.

Thinking about it, he fell asleep unconsciously.

Today is also because I am too tired. I have taught for eight hours in a row, and I have to go back and forth. As an ordinary adult, I can't bear it, let alone a nine-year-old child?

Li Chengqian slept very deeply this time, until the next day, he was suddenly awakened by a hurried voice.

"Something is bad!"

Li Chengqian opened his eyes in a haze, and at this time the sky just dawned, but he saw a small yellow gate rushing into the East Palace.

Call out: "The big thing is bad!"

Such behavior, if it was in normal times, would have already been punished with [-] boards.

Guan Lishi directly blocked Xiaohuangmen.

"What's the panic?"

"Your Majesty is looking for His Royal Highness the Crown Prince to Tai Chi Palace!"

"what?"

"The ministers are already waiting in the Tai Chi Palace!"

Xiao Huangmen said again.

"what's up?"

"Your Majesty didn't say anything, he just said it was a big deal! The villain dare not neglect!"

"Understood, you go down, I will inform His Royal Highness the Prince."

After Guan Lishi finished speaking, when he turned around, he saw Li Chengqian in front of him.

"Go! Go and see!"

Something important must happen at this time, so Li Chengqian hurried to the front.

"His Royal Highness, you are not dressed properly!"

Li Chengqian ignored him and just walked forward, Guan Lishi had no choice but to shout:

"Come here, prepare clothes for His Royal Highness!"

In the end, Guan Lishi had to take Li Chengqian's clothes, and then followed...

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.When the flying speed of the locusts is 10km, they actually 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.
