Three Kingdoms: A five-year-old bear child who saves Cao Cao at the beginning

Chapter 80 Reward, Black Powder Formula!!

Changsha City.

Liu Biaohui and the other advisers were drinking and having fun again, waiting for news.

This time, they believed that Cao Qiao was absolutely difficult to fly.

In this case, even if the immortals come, they can’t leave.

“Report!”

At this time, the outside probe horse quickly came to report.

“Coming?”

When everyone saw this, they couldn’t help but lift their spirits.

“Lord Qiyu, the latest news on the front front, that Cao Liao snatched Huangzu’s ship and broke through!”

“Now it has entered the Yangtze River!”

……

“What?”

Hearing this, everyone who originally had a smile on their faces jumped up at once.

Zhuge Liang’s smile completely froze.

He, failed again?

“What the hell is going on?”

Liu Biao was also going crazy at this time, “What is Huang Zu eating?” ”

“How could that bear kid rob his boat?”

“It is said that the bear child’s divine power is amazing, one person held a tree, smashed the camp, like entering no man’s land, and they don’t know what weapons are used, it seems to be a thunderbolt, our army is in chaos, they take advantage of the chaos!”

Tanma Road. Liu Biao sat down solemnly.

Long time not 093 language.

This time, he was humiliated to his grandmother’s house.

He was defeated by a bear child in Wancheng with Cai Yao’s 100,000-strong army, and then broke all the way into the hinterland of Jingzhou, connected several cities, plotted against his two generals, and even exchanged hostages under his Changsha city, and then calmly left.

Pass it out, where will his face go? His prestige will plummet.

“Who is this bear child?”

“Is it really an immortal?”

Cao Liao sat on the boat, all the way down the river, lying on the bow of the boat blowing the sea breeze, eating snacks, and having fun.

This time, he can be said to have completely teased Liu Biao.

He came and went freely in Liu Biao’s territory, did whatever he wanted, and also obtained two generals, Wen Ping and Huang Zhong.

Liu Biao is afraid that he is already mad.

“Dingdong, you are naughty, teasing Liu Biao, Huang Zu and others, and escaping in the encirclement!”

“Get 1,000 sets of body armor reward, black powder manufacturing process!”

The sound of the system sounded at this time.

“I’m going, the black powder making process?”

“This NB!”

When Cao Qiao saw the reward, he immediately became excited.

Black powder this thing, future generations know what the main ingredient is.

However, when you want to actually make it yourself, you will find it very difficult.

Grinding methods, material ratios, are huge problems.

In this era, it is even more difficult, and those basic materials are difficult to obtain.

Sulfur, saltpeter, charcoal.

Charcoal is easy to get, but where do you look for sulfur and saltpeter in this era?

How to process after finding?

If you are only on your own, I don’t know how long you have to explore to succeed.

With this process recipe, everything is much simpler.

Above the process, it will be written clearly how to extract and process sulfur and saltpeter, which will save Cao Qiao a lot of trouble.

“I understand the principle of this leverage!”

Huang Yueying came out of the cabin at this time and said excitedly: “Because of the existence of these pulleys, the action of force is divided into several segments!” ”

“It’s like a lever that is three times longer at one end than the other, then the force is three times as long as the other end!”

When Cao Liao heard Huang Yueying’s words, he smiled slightly and said, “Your understanding is very good, but it’s not that simple!” ”

“I have a book here, I was thinking of giving it to you later!”

“Since you like research so much, I’ll give it to you first!”

……

Cao Qiao took out a junior high school physics book and handed it to Huang Yueying.

Through Cao Qiao’s understanding of Huang Yueying during this time, Huang Yueying is definitely an engineering talent, and she will definitely become her helper in the future.

It’s better to give her this physics book early.

“Books? What kind of book is this? ”

When Huang Yueying saw the book that Cao Qiao gave her, she was immediately taken aback.

This kind of book is not available in this era.

Although there is now paper, generally paper exists alone, and there is no case of synthetic books.

The books of this era are still bamboo simple.

On TV, you can often see Cao Cao and reading books with bamboo Jane.

Therefore, Huang Yueying was very shocked to see this kind of book by Cao Qiao.

In particular, the words on this book are so small and neat, it is simply incredible.

“This is the Book of Heaven!”

Cao Xiao smiled and said, “This book is called physics, that is, a book specializing in the study of various forces!” ”

“After you study this book, you will understand the true meaning of the principle of leverage!”

……

“Tianshu, it turned out to be Tianshu, no wonder…”

Huang Yueying was immediately excited.

But soon, she looked embarrassed again and said, “I can’t understand the text on this!” ”

“Although these words have similarities to ours, many of them I don’t know what they mean!”

“Oh, forget you can’t read simplified characters!”

“And Arabic numerals and symbols!”

Cao Qiao patted his head, “Come, I’ll give you the basic knowledge of reading the Book of Heaven first!” ”

“This number is called the Arabic numeral…”

“Speaking of Arabic numerals…”

“That… I’d better show you elementary school math first! ”

“If you don’t learn elementary school math, you can’t learn this…”

Cao Qiao was fine now anyway, and began to teach Huang Yueying to learn knowledge.

After starting to teach, Cao finally understood what genius is.

Primary school mathematics, Huang Yueying learned it all in three days.

What Arabic numerals, all kinds of mathematical symbols, are easily mastered.

By the way, Huang Yueying also learned some basic simplified characters.

Three days later, Huang Yueying studied junior high school physics again, and it turned out to be very smooth, and she hardly even needed to teach too much from Cao Liao.

Many times, Huang Yueying just researched by herself, but she really couldn’t study it, and then asked Cao Liao for advice.

And what makes Cao Qiao inferior is that junior high school physics, in fact, he has long forgotten.

Therefore, the help he could give to Huang Yueying in the end was very limited, and it was basically Huang Yueying who studied it herself.

“This time to rob Huang Yueying is really the right grab!”

“If I were to slowly study these physics knowledge myself, I was afraid that my head would explode, and I might not be able to pick it up again!”

“Now I don’t have to worry about this!”

“Just leave it all to her!”

“According to this progress, I am afraid that in a month at most, she will be able to eat the first volume of junior high school physics!”
