A telegram was sent to Chang'an City.

Cheng Chubi received the telegram with a faint smile on his face.

It's finally here, is this time finally in Europe? It seems that in the next two or three years, it should be on the European side.

Cheng Chubi's hanging heart was also put down.

You must know that Cheng Yanjin still loves his Hazi very much, these two children have not been seen for several years, and this time they finally met, it is not good to stay for a while.

After all, I don't know if I can see them in this life.

Sometimes, it's clear that they're still alive, and you just can't see them.

Both of them are emperors, who manage a large country, and they can't leave at all.

Perhaps, when they get to Cheng Yanjin, they will put down the power in their hands and get their country's affairs done, and maybe they will have time to leave.

"Well, when I'm the same age as my father, I'm going to travel around the world." Cheng Chubi thought for a while and said, "The world is so big, I want to go and see it." ”

I have to say that although Datang laid down the New World decades ago, Cheng Chubi really hasn't been to the New World.

"Well, if the prince grows up, he should also go to the New World for a walk, as the crown prince, he can't always be in the Tang Dynasty, the New World is also very important."

Every year, tens of millions of people come and go to the New World, and many of them settle in the New World and seize the vast territory of the New World.

"Your Highness." A figure walked in from outside and said, "Your Highness, according to the report from the Academy of Sciences, they have made plastic." ”

"Plastic." Cheng Chubi sighed and said: "I don't know if it's good or bad, plastic is a good thing, and plastic will always be indispensable in life in the future." ”

"However, this thing is not degradable and is easy to form pollution, hey!"

Plastic in later generations, can often be seen, there are plastic in the streets and alleys, but plastic is easy to form pollution, in scientists in the body of many marine fish found irredegradable plastic.

However, all walks of life have no way to give up the use and manufacture of plastics because of their needs.

"Pass on my order, plastics are valuable, and they can only be produced in industry, not in daily production, and can only be used in industrial products." Cheng said: "At the same time, increase publicity and use bamboo products, such as baskets, baskets, dustpans and other items, and use bamboo if you can use it." ”

The climate of Datang is still very mild.

Bamboo has grown to both sides of the Yellow River, and some animals that can only be seen in Southeast Asia in later generations are still present in this era.

Crocodiles, hornbills, rhinoceros, elephants and other animals, there are also markets along the Yellow River.

In later generations, some so-called heirlooms said that Xiangqi was invented by Tianzhu, because there were no elephants in the Central Plains, let alone elephant soldiers.

In fact, there are not only elephants in the Central Plains, but also the hometown of elephants.

The meaning of Yu is the meaning of the hometown of the elephant.

It was only in later generations that the climate changed, and the elephants slowly migrated south, so the Central Plains elephants slowly disappeared from the sight of humans.

And the elephant in chess is the meaning of the elephant, and it is also the meaning of the phase, the image of the prime minister, and the elephant of the elephant.

In this era and time, because Cheng Chubi came from later generations, he also implemented protection rules for some animals, thinking that even if it is a long time in later generations, there are still elephants, and no one will be stupid to say that there are no elephant soldiers, no elephants, and no chess in China. I want to talk with more like-minded people about "Crossing Starts from Zhenguan", pay attention to "excellent reading literature" on WeChat, talk about life, and find confidants~
