After broadcasting the ancient times live, I handed the system over to the state.

“A long, long time ago, our ancestors learned to farm. We are an agricultural civilization with a long history, and we started using fertilizers a long time ago.”

As Zhu Qinggu just mentioned, many people then traced the origins and realized that the fertilizer formula was something passed down from their ancestors.

"Manure is good for fertilizing fields," is a common saying among the elderly. However, natural organic fertilizers are still too weak and slow to work.

"At that time, we were using fertilizers imported from abroad. Later, our national consciousness rose to an unprecedented level, and we ushered in a period of favorable policies. In 1937, we finally had our first fertilizer plant."

"That's the Yongli Ammonium Sulfate Plant! We Chinese can finally make our own fertilizer!"

That period of history was also a humiliating one, but it still produced a large number of patriots who were dedicated to saving the country.

Every time Zhu Qinggu saw this scene, he felt something strike his heart.

People under the sky also know more or less about that period of history.

There were even many people who said they wanted to rush over and kill those who were not living a good life. If they didn't have a bit of courage, the Chinese civilization would not have survived one crisis after another.

When this period of history was mentioned again, Zhu Yuanzhang kept cursing those Tartars, those barbarians, and those Japanese.

Zhu Biao knew that as long as he sent people there to investigate and find out if there was silver and copper, the people there would be better off becoming mine slaves, or at least skinned alive or cast into mounds of corpses.

In 1941, Yongli Chemical Industry Company named Hou Debang's newly developed alkali production method the "Hou's Alkali Process," but it was never put into production due to the outbreak of war.

"After entering the new era, we only have two fertilizer plants on the verge of bankruptcy, which can only produce a pitiful few thousand tons, which is far from enough to meet the needs of 600,000 mu of farmland. What about the output of other countries?"

"The United States, 426 million tons; the Soviet Union, 124 million tons; Japan, 62 tons..."

……

"We are truly impoverished and weak." Zhu Zhanji could clearly see a lot from the data comparison.

Even Zhu Zhanji felt humiliated.

Even if China was invaded by foreign races in the middle of the journey, it would soon regain its position as the hegemon and leader. When has it ever suffered such grievances?

"Fortunately, we stood up, and China was prosperous and strong in Miss Zhu's era," Zhu Zhanji said.

"The sky is excellent, making me even clearer about the saying that there are always people more capable than oneself and heavens beyond heavens." Yongle Zhu Di's vision was no longer limited to the northern lands.

He also set his sights on the sea, and even on Southeast Asia, a region surrounding Asia.

What kind of general was he, the one who led the Northern Expedition?

He also wants to become an Asian governor like Emperor Taizong of Tang!

The world is too far away for him to think about, but Asia is something he can dream about.

Wait a minute, the name "Asia" sounds awful. If we just divide it according to the Nine Provinces, the original Asia should be called Yuzhou, North America should be called Qingzhou, Central Asia should be called Jingzhou, and Europe should be called Liangzhou…

"China needs fertilizer, and the land of China needs fertilizer, but where does the fertilizer come from?"

"Initially, the Soviet Union assisted in building our project, and we imported equipment from there, which led to the establishment of our fertilizer plant. However, until the 1970s, we were still using fertilizers exported from Japan, even though we already had our own fertilizer plant."

"Because our technology is outdated, our output is low, and our costs are high."

"Later, the international situation began to improve, and our relations with European and American countries improved. Only then were they willing to export technology and equipment. We emptied our coffers and finally built thirteen fertilizer plants across the country."

"And our chemical technology has finally reached a new level."

"Being able to manufacture fertilizers means that the manufacturing level of our pesticide industry and agricultural machinery industry has reached a new level."

"Our grain production has also gradually increased."

"At first, we started by repairing parts for fertilizer plants. Gradually, in the 1980s, we finally successfully developed our first 520,000-ton urea synthesis tower!"

"Our fertilizer shortage finally ended in 08!"

"Currently, we are the world's largest producer and consumer of fertilizers, with our annual fertilizer production accounting for more than 30 percent of the world's total, and we even export fertilizers."

As Zhu Qinggu spoke, tears welled up in his eyes.

"We have walked this road for too long and too far, but thankfully, through the struggles and efforts of several generations, we have finally managed to raise our heads and straighten our backs!"

Under the Canopy

“What heroes, what ghosts? These are the real heroes of later generations.” Li Qingzhao was also moved by Zhu Qinggu’s words.

They only vaguely felt pleasure, a trembling, irresistible sensation.

We've climbed back to the top step by step from the trough. From today onwards, you can no longer make me hold my head high when I speak!

They then understood that Zhu Qinggu's earlier statement about dignity being found only on the edge of a sword meant that the international situation in later generations was truly one of bloodshed, especially the video about the food dispute.

For billions of people in future generations, fertilizers will also be an important part of food production, and the competition involved will be no less intense than before.

"This is the history of fertilizers in our country. I've only given a brief overview. There are many thrilling details, but I won't go into them."

"Then let's briefly talk about some of the manufacturing methods for fertilizers." Zhu Qinggu knew that the industrial conditions of ancient times were definitely not capable of producing modern fertilizers, so he was just going through the process once.

In fact, the fertilizer they had been researching for quite some time already, and after seeing that factory, they knew it was something they couldn't produce themselves.

Those watching the sky kept watching, and the system data showed that not many people had left.

"The main fertilizers used on crops are nitrogen, phosphorus, and potassium fertilizers. Phosphorus and potassium fertilizers depend on mineral resources, so the focus has always been on synthetic ammonia, which is nitrogen fertilizer."

"Aren't you curious about the composition of the air we breathe every day?" Zhu Qinggu asked.

Under the Canopy

"Later generations have studied it in such detail, going up to the heavens, down to the earth and the sea, thoroughly researching the human body, and even the air itself?"

What other components are in this air?

"Of course! I'll fart and let you smell it, then there will be fart in the air, right?"

"..."

People under the canopy also took several deep breaths of air out of curiosity, trying to guess what else was inside.
