Traveling through history leaving a name

Chapter 58 The Study Room
Soon, Zhang Qingfeng invited Cao Cao and his party to his study.

Zhang Qingfeng's study is very large, almost [-] square meters.

Entering the study, at a glance, you can see that one wall of the study is lined with neatly arranged bookshelves.

The bookshelves were filled with densely packed books or manuscripts.

On the wall of the study room, there are many calligraphy and paintings, which are usually written by Cai Wenji herself.

In the middle of the study, there is a glass tea table and sofa, which is where Zhang Qingfeng rests and drinks tea.

The windows in the study room use full-frame glass windows, which provide very good lighting.

Next to the window is a set of tables and chairs. This is where Zhang Qingfeng works, and all his design drawings are drawn here.

There is also a small door by the window. Opening the door leads to a balcony. The balcony is full of flowers and plants. Cai Wenji usually helps to take care of it.

After Cao Cao and his party came to Zhang Qingfeng's study, the next second, there was only surprise in their eyes.

Beautiful and tidy, this is the first impression everyone sees this study.

Of course there are all kinds of unspeakable feelings.

Very elegant, very elegant, very fashionable.

"Sir's study is really different." Cao Cao looked at Zhang Qingfeng's bookshelves full of books, his eyes full of envy.

"Everyone, please sit down." Zhang Qingfeng motioned for everyone to sit down on the sofa in the study.

He took out a stack of manuscript paper from the bookshelf and handed it to Cao Cao.

"This is the blueprint for the galleon and river gunboat."

"This is the model." Then Zhang Qingfeng took out two ship models from the bookshelf and put them on the coffee table.

Cao Cao took the design drawing of the Galen ship from Zhang Qingfeng, flipped through it, and suddenly looked confused.

Then, he handed the drawings to others, and he picked up the models of the two ships and looked at them. In his opinion, looking at the drawings is not as real as looking at the models.

"Sir, why don't you tell us the specific situation of these two ships." After watching for a while, Cao Cao said to Zhang Qingfeng.

"Okay." Zhang Qingfeng nodded, pointed to the model of Galen's ship and said, "This kind of ship is called Galen's sailing ship. It is specially designed to sail in the sea and can withstand strong winds and waves."

"This kind of ship is 22 feet long, 60 feet wide, [-] tons in displacement, and [-] tons in load. Oh, the ton I'm talking about is a unit that is bigger than a stone. One ton is equal to two thousand jin, and three hundred tons is [-] jin." Zhang Qingfeng explained.

"This kind of ship is mainly used for ocean-going trade. Its fastest speed can reach eight knots... that is, sixty miles per hour (an hour in ancient times is equal to two hours), but it can also be used as a warship. It is equipped with More than 30 artillery pieces, capable of sinking enemy ships at a distance of 500 meters... 250 paces..." Zhang Qingfeng explained.

Zhang Qingfeng explained for a long time. He found it difficult to chat with the ancients. He needed to explain many units of measurement with data from this era.

"Sir, what is artillery?" Cao Cao asked after listening to Zhang Qingfeng's words.

"An artillery is an enlarged version of a flintlock gun. The muzzle of a flintlock gun is only as big as a finger, right? But the muzzle of an artillery gun is the size of a bowl. It can shoot iron balls as big as a bowl and fly more than ten miles. It is very powerful." Zhang Qingfeng said in words that Cao Cao could understand.

Cao Cao had seen a flintlock gun, and he understood when Zhang Qingfeng said this.

It's just that he doesn't understand how to launch such a big cannon, and can it be picked up?

"Who can lift such a big musket?" Cao Cao asked immediately.

"No one needs to lift it, just put it on the ground." Zhang Qingfeng replied.

"Oh." Cao Cao nodded and understood: "Such a big musket must be very powerful, right?"

"Is it powerful?" Zhang Qingfeng thought for a while and said, "It can almost penetrate the thickest city gate from hundreds of meters away."

"Really?" Hearing Zhang Qingfeng's words, Cao Cao stood up excitedly again.

"Of course it's true. If the prime minister doesn't believe it, you can ask Li Bai to take you to the military factory tomorrow to adjust a few guns and try it out." Zhang Qingfeng said.

"Okay, okay, okay, hahaha, if there is such a sharp weapon, then it will be much easier to attack the city." Cao Cao suddenly put his hands on his hands and laughed.

"Prime Minister, let me introduce you to this river gunboat." Zhang Qingfeng pointed to the model of the river gunboat.

"This gunship has a displacement of [-] tons and can also be equipped with [-] cannons. It is powered by [-] oars on each side."

Zhang Qingfeng introduced: "This kind of ship is very flexible in navigating in rivers and lakes. In addition to artillery, it can also carry hundreds of sailors. If it meets Sun Quan's building ship, it will be separated by hundreds of steps. It sank at the bottom of the river."

"Okay, with this kind of boat, so-and-so will no longer be afraid of the sailors of the Sun-Liu coalition army." Cao Cao clapped his hands and shouted.

"Several of my students are planning to put the steam engine on the gun boat. By then, this kind of boat will no longer need paddles and can run fast in the water." Zhang Qingfeng said.

"How fast?" someone asked.

"Several times faster than any rowing boat." Zhang Qingfeng replied.

"hiss!"

Hearing Zhang Qingfeng's words, everyone gasped.

"So you can run if you can't beat it? No one can catch up?" Cao Pi said.

"It can be said that, and at the same time, it can also be understood that no one who is targeted by this kind of ship can escape." Zhang Qingfeng said.

"How long will it take to build such a ship?" Cao Cao asked.

"It should take a year or two." Zhang Qingfeng said.

Moving the steam engine onto the ship is not as simple as imagined, it takes many attempts, and the difficulties are beyond the imagination of ordinary people.

"Okay, as long as I have this kind of boat, I will be able to survive the Yangtze River's attack by Sun Quan." Cao Cao said very happily.

"Mr. Ruixiang, can I have a look at your collection of books?"

At this time, Jia Xu who was on the side asked Zhang Qingfeng.

"Okay, everyone is free to read the books in this room." Zhang Qingfeng said to everyone.

After hearing Zhang Qingfeng's words, everyone except those few illiterate generals were quite moved.

Jia Xu looked around in front of Zhang Qingfeng's bookshelf, finally took out a book of natural science and returned to the sofa.

Seeing Jia Xu's actions, others also went to the bookshelf to get books.

Cao Cao was even more impolite, he directly took several books.

Different from others, Cao Cao flipped through the books while chatting with Zhang Qingfeng, and sometimes he would humbly ask Zhang Qingfeng for advice when he found something he didn't understand.

"Hey, sir, what is this?" Cao Pi asked Zhang Qingfeng with a stack of manuscript paper. It turned out that he came to Zhang Qingfeng's desk at some point and saw a pile of design drawings on the desk.

"This is the design drawing of a steam locomotive." Zhang Qingfeng explained.

"Mr. Ruixiang, I rode a steam locomotive with Inspector Li Taibai when I came here. Is it different from this steam locomotive?" Hearing Zhang Qingfeng talking about the steam locomotive, Cao Cao thought of the kind of steam locomotive he saw yesterday. So he asked Zhang Qingfeng.

"You're talking about a steam locomotive that transports rails, right? It's refitted with a small steam engine, and the power is very small. It can only pull a few thousand catties at most."

Zhang Qingfeng explained: "The steam locomotive I designed can move more than a dozen carriages, and it is a big thing that can pull dozens or millions of kilograms of stuff."

"Oh, that's it." After hearing Zhang Qingfeng's words, Cao Cao nodded to express his understanding, it was just because of his strength.

"Sir, would you like to become an official?"
