Ming Dynasty, Zhu Di: Dad, why are you not dead?!

"Hiss~~~Penicillin~~~~".

Penicillin is a very common medicine in later modern times, and the price is also very ordinary, you can buy a large barrel for a few dozen yuan.

But in ancient times, penicillin was no different from a miracle drug, and gonorrhea, syphilis, bacteremia, various tuberculosis, sepsis, and typhoid fever could be treated.

After the appearance of penicillin, incurable scarlet disease and suppurative laryngitis can be cured.

Zhu Yijun's belief that penicillin is a miracle drug in this era is really not exaggerated, because ancient people have never used penicillin and have no resistance, so the effect of penicillin will be obvious.

In the forties of the twentieth century, a ton of penicillin was priced at $800 million, and at this time, $800 million could buy nearly 700 tons of gold.

In other words, one ton of penicillin is worth nearly 700 tons of gold.

One ton of penicillin can buy 5,000 main battle tanks, 4,000 bombers, or 530,000 M2 heavy machine guns, which is the size of the armament of a military power in the world at that time.

In the forties of the twentieth century, an aircraft carrier in the United States was worth 40 million dollars, and this only required 100 pounds of penicillin.

The reason why it is so precious is because the role of penicillin in World War II is undoubted, and it is known as the "life-saving medicine" of World War II.

It can kill a class of antibiotics that kill bacteria during the bacterial reproduction period, effectively kill various bacterial infections in the early stage, and has few side effects, and it is not easy for bacteria to develop drug resistance, saving the lives of countless wounded on the battlefield.

It can be said that with penicillin, the number of deaths due to disease has been halved.

As for cement, in Zhu Yijun's heart, it is no less effective than penicillin.

If you want to get rich, build roads first.

This is a sentence engraved in the memory of many people in later generations.

In Daming, it is very difficult to build roads, and the official roads are paved with stones, and it is difficult to make them smooth.

Cement, on the other hand, is a good material for road construction, with low cost and simple construction methods.

Of course, cement can be used not only for road construction, but also for civil construction, water conservancy and many other projects.

It is not an exaggeration to say that cement is one of the greatest inventions in human history.

Cement is not alone, cement, sand, stones, brother three peach orchard three knots, the beautiful name is 'concrete', harder than cement.

This one is relatively easy.

Later, the steel bar was mixed in, and it was called 'reinforced concrete', which was more hard, which could not be achieved in the Ming Dynasty.

The building strength of the steel bar is currently not built.

With this thing, the difficulty of building a road is more than ten times smaller, and the speed is much faster.

Why is there a saying that the emperor is far away, because the ancient roads are impassable, if a letter is sent from the capital, it will be a month or two later to the south.

If there is a smooth official road, then this time can be shortened by several times.

If the roads built of cement could be all over the Ming Dynasty, then Zhu Yijun's rule over the whole country would be much less difficult.

Zhu Yuanzhang said suspiciously: "Our first stage of reward is the seed planting and processing technology of upland cotton, we know cotton, what is upland cotton?" Is it another variety of cotton? "

"Our second stage reward is the Barefoot Doctor's Handbook, what is this, a book? A book gives us a fart, this reward is not good. "

Immediately afterwards, Zhu Di and Zhu Qiyu's questions followed:

"My first stage reward is the Whitney Ginner, is this the same as Daddy, is it also about cotton?"

"I first stage ..."

"Stop, Stop, Stop, Stop!!"

Asking questions one after another, Zhu Yijun only felt that his head was bigger, and he didn't forget to glance at Zhu Youzhen and signal him to shut up.

Zhu Youzhen bowed his head weakly and shut up.

"Come one by one, I'll answer one by one, everyone asks together, who do I answer first?"

"Of course it's us!!"

Zhu Yuanzhang snorted coldly and squinted at Zhu Di: "You, do you want to fight with us?" "

Zhu Di smiled: "Dad, how dare I." "

You're a father, I'm a son, of course I don't dare.

"Emperor Jingtai, do you want to fight with us?"

Zhu Qiyu smiled: "You please first." "

You are the ancestor, what will I fight for?

"And you..."

Zhu Youjian learned to answer: "Too... Emperor Hongwu, I haven't opened my mouth yet. "

All of a sudden, Emperor Hongwu looked at all directions, and he didn't meet an opponent, which was called a domineering one, and the next moment, a smile appeared on his face: "Emperor Wanli, you tell us about it." "

Zhu Yijun chuckled: "You know cotton, in fact, it has been around for thousands of years, but its adaptability is not strong, it can only be planted in the southeast coastal area, and the yield is very low, and the price of the products produced is very high, only the rich can afford it." "

Zhu Yuanzhang patted his head: "After we ascended the throne, we realized that the winter was getting colder and colder, so we vigorously promoted cotton planting, although it can adapt to most of the environment, but the problem of yield is still worrying us, and many people still can't afford cotton to keep out the cold." "

"Then you don't have to worry now, upland cotton is native to the Americas, not only has good toughness, high fiber content, and the planting yield is also very high, which is better than the existing cotton varieties in the Hongwu Dynasty."

Zhu Yijun looked at Zhu Di: "Emperor Yongle, you guessed right, the Whitney cotton gin is indeed related to cotton." At present, Daming separates cottonseed and cotton fiber to produce clean cotton, which can only be used with both hands, and can only produce about 0.5 kg of cotton a day, and the production efficiency is outrageously low. "

"With a cotton gin, we can produce 25 kilograms of clean cotton a day."

Compared with cleaning cotton with bare hands, the cotton ginning mechanism is ingenious, there is a cylinder with steel teeth on it, turning the cylinder, the steel teeth can tear off the cotton lint, and use centrifugal force to filter out the cotton seeds, the efficiency is dozens of times that of bare hands.

Zhu Yijun smiled slightly: "The reward of the two of you can be described as a match made in heaven. "

"Fourth, cooperation?"

"Definitely cooperate, Dad, you give me the seed planting and processing technology of upland cotton, and I will give you the manufacturing method of cotton gin."

Zhu Yijun coughed lightly: "Emperor Hongwu, Emperor Yongle, if you want to plant cotton on a large scale, I suggest you use Kunlun slaves, remember, it is the kind of Kunlun slaves that are particularly black, and this kind of people have a special bonus effect on cotton planting, picking, and processing." "

"One more thing, remember to castrate Kunlun Road."

Zhu Yuanzhang and Zhu Di had a question mark on their faces.

Does Kunlun have a bonus effect on cotton?

Although they were strange, they decided to go back and buy some Kunlun slaves from those red ghosts to try.

Well, since Zhu Yijun emphasized it, let's castrate it first.
