"This thing...... Is it soap? ”

Zhu Biao looked at the pieces of lard made of things. Except for the powerful Mu Ying when he stirred, the rest of the time was almost created by him little by little. He looked at Zhu Su, who was sitting on the threshold, obviously only moving his mouth but looking like "Master, I am really diligent", and wondered: "This thing is made of lard, and when it is smeared on the body, doesn't it add more oil?" How can you get rid of oil? ”

"This involves a subject of knowledge called 'science'. It's not that simple. Zhu Su said lazily. The first ones should be cold, and the eldest brother will take them to wash his hands, don't you know? ”

"Reasonable!" Zhu Biao nodded, and pulled out the first molded soap from the wooden box. Who knew that the white soap slipped to the ground and was stained with a little dust.

"Ah, this thing is so slippery and doesn't leave your hands!" Zhu Biao was surprised, then squatted down and carefully picked up the soap.

Zhu Su looked at his cautious appearance, and couldn't help but have a little bad taste in his heart: he didn't expect that the first man in history to pick up soap turned out to be Zhu Biao, the prince of Yiwen......

"This thing is dirty, can it still be used?" Mu Ying asked Zhu Su.

"It's okay, it's okay, take the water and wash it off." Zhu Su waved his hand and didn't look at the soap. He just felt the heat panic and stood up to find the remaining quicklime. "Brother Mu Ying, you are sweating hot, why don't you also wash your face with this soap."

Mu Ying nodded and took a bar of soap as well. Although he believed Zhu Su, he was still hesitant about the soap: how could something made of lard be used to clean his head and face?

But hearing Zhu Biao's exclamation behind him, Mu Ying hurriedly turned her head, only to see Zhu Biao surprised: "This thing is so magical, just a light touch, this hand is so refreshing!" ”

"Oh?" Mu Ying also found a basin of clean water, wet her hands and smeared soap. Strange and strange, the soap made of lard is not greasy at all, and the bubbles on your hands are more comfortable than the best pancreatic bath beans. When I took the water and flushed it, I felt very refreshed, and my hands had never been so refreshed.

He bowed and wiped the water on his face, smeared some soap, and then took the water and flushed it. I felt that my face was extremely fresh, and the sweat stains that were sticky were gone.

"This science, how amazing is it?" Zhu Biao took the soap and looked left and right. "It's obviously made of lard, but it's not greasy."

"It's magical." Zhu Su had already opened a cold melon and handed it to Zhu Biao Muying. And that's just a small end of what you can do. If everyone promotes, it will be easy to enrich the people and strengthen the country. ”

"Enrich the people and strengthen the country!" Zhu Biao's spirits perked up, and he was about to ask carefully, only to feel that his hands were cold, and he couldn't help but exclaim: "Why is this cold melon so cold?" ”

"What's so strange about this, I got a basin of ice and chilled it for a while." He pouted behind him, and sure enough, in a basin behind him, a large basin of ice was shining in the sun, and the cold was visible to the naked eye.

"July Ice...... Is this also a wonderful use of science? Zhu Biao remembered that Zhu Su had just gone to get quicklime, and his eyes were shining.

"Sort of. In fact, during the Song Dynasty, saltpeter was used to make ice, which is not unusual. ”

"It's just that they know it, but they don't know why." Zhu Su said. Bow your head and nibble on a large mouthful of cold melon. He puffed up his mouth and continued: "The science of science is the science that explains why everything in the world is so. ”

"Dad has nothing to do, he always catches me to ask about policies and systems...... As I said earlier, where is there a system that is not easy for eternity, this knowledge is the basis for my Han family to be invincible in the world! ”

Although Zhu Biao, the "...... of science", is still young, his vision is also extraordinary. How can you not see that Zhu Su's "science" is actually promising?

Not to mention the rest, the most expensive thing about this soap is a little lard, which can make such a good thing to remove stains and stains. How much stronger than a pancreas is a thousand times? If it is well promoted, won't everyone be able to use it?

As it becomes peaceful today, the epidemic is the number one problem faced by the Ming Dynasty. Zhu Biao heard when he was a child that epidemics are mostly born in dirty places, but the people are poor, where do they get pancreas to bathe beans and wash their bodies?

Wouldn't it be a great merit if everyone could use this soap, and if everyone could use it, the epidemic would be greatly reduced.

Mu Ying's face was pale, he put the cold melon aside, and said, "The world is invincible? Tell me about it! ”

Zhu Su was stunned for a moment, and when he saw that Zhu Biao's attention was also attracted, he swallowed the cold melon in one gulp, and organized the wording first: "Two brothers, the world says that the barbarians are fierce and difficult to match. But I ask you, why in the past when the Zhou Dynasty, we waited for the ancestors of China, and a vassal state could chase away the barbarians and expand the territory. ”

"In the pre-Qin period, there was only one strong army, which could make tens of millions of Hu people in the north fearful."

"But later, the barbarians became a big problem for my Han people. Often the power of the country can only be countered. ”

"This ......," Mu Ying lowered her head and pondered. Although he is also studious, after all, he was born poor, and he only knew the words when he was a little older, and he knew very little about ancient things. Zhu Biao also thought about it and said, "Isn't it because of the Zhou Dynasty and the pre-Qin Dynasty, when the martial arts were abundant and everyone was strong?" ”

"That's one reason too." Zhu Su said. "But in fact, there is another extremely important factor, that is, the generation difference of weapons!"

"Weapon generation?" Mu Ying's eyes froze. As a general, he is most sensitive to the word "weapon".

"Hmm." Zhu Su nodded. "Barbarians are not three-headed and six-armed, and if you talk about the length of the development history, you can't catch up with my brilliant China! Why can you always commit murder on the head of my Han people? It's because we don't pay enough attention to technology these days! ”

"At the time of the Zhou Dynasty, the bronze sword was beneficial to the world! At that time, the barbarians were at most just bone arrows and stone forks, how could they be defeated? It is the Duke of Zhou who divides the princes on all sides, often only a few hundred people, and can open up a large territory, so as to teach my descendants of Yan and Huang to live in peace in all directions and lay my foundation in China. This is the reason for the generational gap in 'weapons technology'. ”

"When it comes to Qin, Qin Jian is even more prestigious! The Ruishi of the Qin State held a human head in his left hand and a long sword in his right hand, showing his might in the heart of the barbarians, driving them away, like chasing dogs! Among them, how could there be no Qin Jian's skills! ”

"Most barbarians are not good at weapons, and can only learn from civilized races such as us. But as long as we wait for the technology to break through the generation gap, the barbarians can only be pressed and beaten by us before they learn new technologies! This is the fundamental way for my civilized race to subdue the barbarians! ”

Speaking of this, Zhu Su's face turned depressed. "Hundreds of years later, the Western technology has surpassed my Huaxia, and there is a generation gap with Huaxia, and the strong ships and cannons have opened to the gate of our Huaxia, plunging this land into boundless darkness."

"At that time, there were often tens of thousands of troops, and it was difficult to defeat the hundreds of people in the West. You can only fill ...... with human lives."

Mu Ying was extremely shocked, he had been listening to Zhu Su talk about the sea and the West, and he already had an embankment for the West in his heart. But I didn't expect that those Western barbarians would be so arrogant that they would dare to break ground on the head of Huaxia hundreds of years later!

Tens of thousands of troops are defeated by 100 people, and they can only be filled with human lives! This...... How can it be!

To use a more corny analogy, tens of thousands of pigs are cut by hundreds of people, and they have to cut to the point of exhaustion and collapse of the blade. This generation difference, is it really so terrifying?

Mu Ying couldn't imagine it.

Zhu Biao knew about the Jurchen Daiming. I was even more angry in my heart: What a barbarian dog thief, how brilliant I have been in China for thousands of years, and what country and what race in the world can be compared with it?

Unexpectedly, hundreds of years later, they were governed into barbarians who were not even as good as the Western Barbarians!

"Then Brother Su, do you know where to start with this 'weapon generation'?" Mu Ying asked.
