"The Earth has suffered too much damage in the hundreds of years of war. It can be said that, except for mountainous areas and a small number of hilly areas, most places are not suitable for planting crops. If you want to restore to the previous environment, you have to rest for more than 2,000 years. The consequence is that if the 600 million Chinese citizens who live on the Earth want to be self-sufficient, they can meet the maximum amount of 400 million to 450 million grain needs. The remaining nearly 200 million people have to rely on our Yanhuang Star to provide. This is a considerable number. One fifth of the surplus of grain per year is supplied to the Earth."

The two century-old wars first increased the temperature of the earth, dissolved the glaciers in the Antarctic and Arctic, and reduced the land. Later, as the war became more and more intense, the earth actually entered the ice age ahead of time, and the temperature suddenly decreased, entering the ice age. Although the temperature on the earth has risen a little after the common governance of the four countries, the average temperature throughout the year is still only around five degrees, and at the hottest time it is only thirteen degrees. If the newly developed crops had very low environmental requirements, the food of more than 400 million people would have fallen on Yanhuang Star.

"I have said before that the Yanhuang star is the best gift God has given us. The United Star of the United States and the Holy Light Star of Europe can all satisfy themselves, but it is not possible on the earth. There is a food shortage of about 100 million people every year. We can exchange food for precious minerals. Food is our main product!"

After waiting for the students to laugh, the old professor continued: "Our biggest buyer on the earth is the Japanese and African Kingdom. As long as you go online, you will know that the Yamato Star of Japan and African Kingdom is a place full of monsters. They don't even meet the food needs of Yamato Star itself. There is no surplus grain to supply the Earth's population. More than half of the more than 400 million people on the earth are supported by us selling food. If we are unhappy, then they will have trouble. By the way, all the students who are sitting here, if Japan and African Kingdom go hungry, no one will object, right?"

"No, no! Those who starved to death to death, and they did all the disgusting things, so they shouldn't live in this world!" All the students made a fuss. Japan and Africa are the real enemy of China, and they can be called deep hatred like the sea. Oh no, it is not enough to describe it as sea. Now they say that hatred is deep like galaxies. During the two hundred-year wars, both countries were mortal enemies, and they fought red in their faces. In the end, they both escaped the disaster because of the United States and Europe. They were really lucky.

There are so many dirty things that Japan and Africa have done. In fact, it has been changed to Yamato, but China ignores it and still calls it the original name.

When Japan brought together many African countries to form alliances. After finding a new planet, it began to extort and suppress the country in a blatant way. The methods gradually escalated, oppressing the pure black Africans to a stage that was worse than slaves. There were even more cruel ones, and finally escalated to massacre. Not long after, billions of pure-bred black people were almost extinct in Japan and Africa.

The horrifying massacre is more cruel than any other time on Earth. After the use of value is gone, it is really heartbreaking to treat the alliance members of that year.

Yamato Star of Japan and Africa has many wild beasts. In addition to the conventional arms, they also have a unit called beast soldiers. They are real mixed animals made of wild beast genes and humans. They have no other consciousness except killing and mating. Only the Japanese can destroy human nature so badly. This beast soldiers are also notorious among the four countries.

In addition to the above two things that made people scold him after hearing this, there is another thing that made the name of Japan and Africa so bad. In addition to the Tiandun Empire, there are two other alien countries, one is the Republic of Reno, the second-level civilized country, the Principal of Velda, and the third-level civilized country. This universe has all kinds of systems. Among these three countries, the Principal of Velda still retains slavery, Japan and Africa.

The construction of the channel from Earth to Yamato Star was also borrowed debts. Because they had too little income from selling domestic minerals, they actually started a slave business. Under the guidance of the so-called Bushido spirit and the will of the emperor, they began to export slaves and prostitutes to the outside world. Everything was about money. As long as they could make money, no matter how dirty or disgusting it was, they were promoted in China. In the Principality of Velda, they also made a famous reputation as a high-end Japanese actress.

The crowd was indignant, Wen Kaida smiled and asked the students to stop and then said: "We all know the shamelessness of Japan and Africa, so we must study hard and do our part to destroy this shameless country."

"Okay! Destroy the little Japanese!" shouted in an unanimous voice.

"Now we continue the topic just now. What I said before, will it have any impact on them if we don't sell grain to Japan and Africa? There must be some, but it will not be as important as we imagined. You must know that they are not only importing grain from one country of China. The Principality of Velda and the Republic of Reno have all had contact with them, but the grain we sell is cheaper..."

"Now the third place for the sale of surplus grain is the Tiandun Empire. In the past, it was too slow to rely on digging basic mines and conventional mines to repay debts. Moreover, my country not only had to pay off its debts, but also had to buy new technology, buy new products for research, and also buy rare minerals and other items that cannot be bought from these three European countries. These all require a lot of foreign exchange." Wen Kaida paused for a moment, and his arm fluttered heavily in the air. "Here, our agriculture has made a huge contribution. Half of the surplus grains required by the Tiandun Empire will be stored and sold in large-scale transactions once a year, which has been exchanged for my country's huge foreign exchange. In terms of the percentage of national contribution, it has reached 32 points, which is only three points lower than the export of minerals. Moreover, the rise is still strong, and in the near future, it will definitely replace minerals and occupy the first export position...."

Good! The freshmen all exclaimed, thirty-two o'clock, what does this mean? One-third of the foreign exchange every year is exchanged for agricultural products, supporting half of the country!

"From next year, the trading activities will be adjusted to once a year, which is very beneficial to our country. At least a large amount of storage costs can be saved... After saying so much, you must understand that you future agricultural workers are responsible for the rise of China. Every little effort of yours is to contribute to the strength of the country. Don't underestimate yourself, saying that farmers are the lowest people in society. The country is that you are silently devoting your own strength to exchange for the opportunity to survive and develop in the universe!"
