I hand over the Wanjie trading system to the country

"In our history, in 627, Li Yi was rebellious, but it should not happen now."

"This 627 year, is it next year?" Li Shimin asked.

Just now Li Shimin wanted to ask how the year was calculated.

"Yes, according to later generations, the year you ascended the throne was 626 A.D., but the first year of Zhenguan we call is actually counted from 627." Papa Chu explained.

Then Papa Chu explained in detail the meaning of AD and how BC and AD were divided in the history of China.

[Historically, the dividing line between BC and AD is the year when Emperor Han Ping ascended the throne, and the history before that is called BC. 】

"Thank you sir for clarifying the confusion." Li Shimin thought for a while, and sorted out the relationship between them.

"In the following three years, locust plagues and droughts and floods occurred consecutively."

"Is it serious?" Li Shimin's back felt cold.

You know, whenever these natural disasters occur, it is generally believed that the emperor at that time was not worthy of virtue, and the punishment was sent down by heaven.

And Li Shimin had just launched the Xuanwumen Change, killed his brother and seized the throne, imprisoned his biological father and sat on the throne.

"It's serious." Father Chu was very speechless when asked.

A place with internal and external troubles, various natural disasters for three consecutive years, you ask me if it is serious or not.

Li Shimin just realized how outrageous his question was after asking.

"Dare to ask, sir, is there a way to deal with these disasters in future generations?" Li Shimin no longer wants to know what happened next, but only wants to know what is going to happen, and whether there is a solution.

There are five common methods of controlling locust plagues in history.

The first is to eat.

"Old Tang Book·Dezong Benji [-]": At that time, there was a great famine in Kanto, and the Fu tune could not be read. Because of the embarrassment of the country, the hungry people in Guanzhong steamed locusts and ate them.

The second is biological control, such as the previous duck brigade.

The third is to use fire to lure locusts at night.

The fourth is to use some plants as insect repellants.

The fifth is to find the eggs and kill the eggs in advance to prevent and control them.

But when the locust plague has reached a large scale, these methods have almost no effect.

I can only watch helplessly as the locusts eat up the crops and leave by themselves.

In ancient times, the only way to deal with drought was to pray for rain, and the emperor issued an imperial edict.

"At present, we don't have a good way to deal with the large-scale locust plague. Our current approach is to monitor and prevent it in advance, so as to kill the locust plague in its infancy."

"If there's a drought, now we can artificially rain."

"Artificial rainfall? Is it a kind of blessing?" Li Shimin asked.

"Cultivation of rain is not a blessing, it is science."

"Science?" Li Shimin felt thirsty for knowledge now.

Upon seeing this, President Hu called a colleague from the Institute of Meteorology to come in and explain in detail the relevant knowledge about artificial rainfall.

Fang Xuanling, Du Ruhui, and Wei Zheng were frantically taking notes, while Zhang Anan rubbed his ink on the side and his hand made a phantom.

"Dad, pay attention to the time." Chuno quietly pulled his father's clothes.

The daily trading time is only 4 hours, and now almost 3 hours have passed.

"After chatting for so long, everyone is tired, why don't we take a break, let's drink tea, eat something and rest for a while?" Papa Chu suggested.

"How long will this passage be closed?" Li Shimin asked.

"There is 1 hour and 11 minutes left in today's time." After finishing speaking, Chuno remembered that the time units on the two sides are different. "More than half an hour."

Li Shimin nodded to show that he understood, the information he received today was enough for him to digest for a long time.

"Then I will trouble everyone." Li Shimin also wanted to see what the people of later generations ate.

The people who came with Li Shimin wanted to stop them, but Li Shimin suppressed those who wanted to speak with a glance.

Li Shimin was originally a resolute and decisive person, with strong determination on some things.

"Do you need to find two more people to serve?" Chuno asked cryptically.

To put it bluntly, you are the emperor, do you want to find some poison testers to eat here?

"No need, just do as the Romans do." Li Shimin replied with a smile.

Li Shimin's idea is very simple, if the people in the supermarket really want to kill him, they definitely don't need to use poisonous tricks.

After all, Guan Yin's force value is here. It can be said that it is easy to want his life.

Besides, since he still dared to come in, it meant that he chose to believe.

Moreover, there is no benefit for these people of later generations to kill him, there is really no need to do so.

Afternoon tea across time and space was quickly prepared and delivered to the conference room.

"Try it, this is a specialty of our side. This tea is called Pu'er tea."

"May I ask where you are, which state capital of Datang?" Li Shimin asked, sipping tea carefully.

"It should be...Nanning Prefecture." Father Chu thought for a while and replied.

"Cuan (cuan four tones) land?" Li Shimin thought for a while and thought of what Chu's father said.

"Yes." Papa Chu nodded.

In the current era of Li Shimin, Province Y is not completely ruled by the Tang Dynasty, so everyone did not continue this topic.

"This is a flower cake, a snack on our side, made of roses."

"Not bad, not bad." Li Shimin was very satisfied, while secretly planning to buy some back for Empress Changsun to taste.

"Then what are these?" Li Shimin asked looking at a pile of convenience food.

"These are convenience foods for future generations," Chuno said.

In the near future, Li Shimin will attack the Turks with an iron fist, and the food and grass must keep up.

"This is called a compressed biscuit, which can be stored for three years and has a strong satiety."

"Two pieces of these compressed biscuits are just a bowl of water, which can basically fill you up."

"Is that true?" Li Shimin stopped drinking his tea, picked up a compressed biscuit and looked at it over and over again.

Fang Xuanling and the others couldn't hide their excitement.

Two words involuntarily emerged in the minds of this group of people - {grain, disaster relief}.

"You can try it." Chuno helped to tear open the package.

"Huh? This taste is much better than dry biscuits!" Li Shimin thought the taste would be bad, after all, compressed biscuits don't look very tasty.

"The main ingredients in it are wheat flour, sugar, oil, dairy products, salt, etc. In addition to being full, it can also maintain some other nutrients needed by the body."

Li Shimin understood this sentence. In the Tang Dynasty, everyone knew that while eating enough, they also needed some other things. Take salt as an example. If you don’t eat salt for a long time, you will lose your strength.

"This is a good thing!" Li Shimin became more interested in other things, "What about the other things?"

"This is called instant noodles. Put dry noodles and seasoning packets in a bowl, soak them in hot water for a while and eat them."

When the system was handed over, the authorities took a lot of countermeasures.

For example, in order to trade with the ancient world, a batch of convenience food packaged with degradable materials was specially customized.

Otherwise, if people from those parallel worlds dig up plastic products in archeology in the future, they will probably doubt their lives.
