Ancient promotion routine

Chen Guogong turned his head deliberately, without looking at Zhang Yanjin, and said disdainfully: "The emperor has already sent all the big ships that can be sent there. Do you need to talk about this kind of method that anyone can think of?"

Originally, they had planned today for the emperor to punish themselves, but they didn't want to be disturbed by Zhang Yanjin. How could he feel better if the originally planned things were ruined like this?

Seeing what Zhang Yanjin said at this time, naturally he must seize the time to reprimand Zhang Yanjin angrily.

Thinking of this, he glanced at Zhang Zhongqian again, and felt that Zhang Zhongqian was responding more and more in his heart.This Zhang Zhongqian repeatedly asked his nephew Zhang Yanjin to fight against them, I really don't know what he was thinking.

Chen Guogong didn't think that a dude like Zhang Yanjin could think of such a thing as the Dongying earthquake. He must have been instigated by Zhang Zhongqian in private, so he dared to oppose them in the court.

When he thought that Zhang Zhongqian would fight against them and not go out himself, but let Zhang Yanjin, a yellow-mouthed kid, go out, he felt more and more uncomfortable, feeling that he was being looked down upon by Zhang Zhongqian.

The emperor was also faintly disappointed. He originally thought that Zhang Yanjin would have some good ideas, but he didn't want Zhang Yanjin to come up with a way to save people by boat.

Just like before, Zhang Yanjin directly ignored Chen Guogong, and just continued: "Your Majesty, the current boats must be unable to move an inch in heavy rain. I have thought of a new type of boat that can be started by ten people at the same time. Unimpeded, and quickly rescued the people trapped inside in the flood."

In China, since ancient times, people have known that bamboo rafts or wooden rafts are tied together to float on the water. This is the earliest boat.Later, when Dayu was controlling the water, for the convenience of commanding in the water, Dayu hollowed out the middle of a piece of wood, stood in it, and floated in the water. This kind of boat was called a canoe.

Later, in order to stabilize the ship, a catamaran appeared again, that is, a thick wooden plank was used to frame the two ships as a bridge to connect the two ships together. It was named after its appearance and was called a catamaran. Boat.

Later, there was a toss of sails and rudders, as well as watertight compartments and waterfowl-shaped hulls.

It’s just that there are few battles on the water in the Great Wei and North Korea, and the ships are only used among the common people. Therefore, most of the ships are small boats like shuttles, without sails and rudders.

A sail and a rudder can control the speed of the ship, and the other can control the direction of the ship, which is an indispensable structure for later ships.The watertight compartment is a magic weapon to prevent the ship from sinking while traveling on the sea.

The watertight compartment is to divide the hull into many compartments, each of which is not connected to each other, so that during navigation, even if some compartments are damaged and flooded, the ship can still drive as usual without sinking.

Not only that, there is another obvious benefit of dividing the hull into various compartments, that is, it is very convenient to load and unload cargo.The ship owner can also manage different cargoes in separate warehouses, which will save a lot of time when they come and go.

The waterfowl-shaped hull is designed to imitate the appearance of waterfowl rowing. To put it simply, the widest part of the hull is placed at the rear of the middle of the boat, which will allow the boat to row under the interaction of water and air. Go faster.

What Zhang Yanjin is going to toss is this kind of sailing ship with watertight compartments, sails, rudders, and a waterfowl-shaped hull.

After all, he bought a piece of land in Dongying, and sooner or later the shipyard will be built, otherwise how will he go to Dongying in the future?This time is also a good time, firstly to help the emperor, and secondly to push the boat smoothly.

"Oh?" The emperor immediately leaned forward and said, "There is such a magical ship?"

"This is the blueprint drawn by the minister, please take a look at it!" Zhang Yanjin took out the blueprint drawn last night.

Li Mingrui stepped down from the side of the dragon chair, took the blueprint from Zhang Yanjin, and handed it to the emperor.

The emperor looked at the very three-dimensional and vivid ship for a long time and couldn't get back his attention. The tall triangular schooner stood on the deck of the bow, like a water bird, and the narrow front and wide rear hulls were lined with neat rows of vertical oars.There is a larger circular wheel at the stern, with many handles protruding from the wheel, which seems to be a place for people to grab.

"Si Youlang, take a look at this blueprint." The emperor handed the blueprint to Li Mingrui.

After Li Mingrui took it, he walked down the steps and handed the blueprint to Si Youlang who came out from among the officials.

Si Youlang is an official belonging to the Ministry of Industry.

The official system of the Great Wei Dynasty was a system of three provinces and six departments. The three provinces were Zhongshu Province, Menxia Province and Shangshu Province, and the six departments were the Ministry of Officials, the Ministry of Households, the Ministry of Rites, the Ministry of War, the Ministry of Punishment, and the Ministry of Industry.

Hundreds of officials perform their own duties, and the Ministry of Industry is in charge of the government of the world's hundreds of workers.And Si Youlang under the Ministry of Industry is in charge of the government affairs of construction and construction, the repair and dredging of the city, the construction of civil engineering, and the procedures of craftsmen.And he is quite an expert in the construction industry of the Great Wei Dynasty.

When Si Youlang and Huang Xiujun saw the blueprint handed over by Li Mingrui, his eyes widened in surprise.Zhang Yanjin is good at drawing architectural drawings, he has long heard of it.

After seeing the drawings of stirrups and saddles drawn by Zhang Yanjin, he was so shocked that he asked for the drawings to observe carefully.

This is really not because Huang Xiujun overreacted. In fact, in the era of the Great Wei Dynasty, everyone drew only planar or superficial drawings. Suddenly, a three-dimensional three-dimensional drawing like Zhang Yanjin appeared. As Huang Xiujun, who was obsessed with architecture since childhood How can you not be surprised?

At this time, the blueprint of such a large three-dimensional building appeared in front of him, how could he not be shocked?

All the civil and military officials of the Manchu Dynasty focused their eyes on Huang Xiujun, wanting to hear the judgment of him, Si Youlang.

After a long while, Si Youlang and Huang Xiujun realized that the emperor and others were still waiting for his reply, so he hurriedly said: "My majesty, although I still don't understand the design of this ship, if it is like Zhang Lu According to the facts, I believe that if this ship is built, the people of Zhongzhou trapped in the flood can be rescued quickly, and the water navigation of our Great Wei Dynasty will definitely develop greatly. If there is another water battle in the future, I, Great Wei, will definitely be invincible!"

As soon as these words came out, there was an uproar.

"Really?" When the emperor saw the blueprint, he was also amazed, but he never expected that the boat drawn by Zhang Yanjin would be so powerful!

"The emperor please allow me to talk carefully." Si Youlang and Huang Xiujun said in high spirits.

He pointed to the triangular schooner on the blueprint and said: "The shape of this thing is like a triangle, and it is pulled by a rope at the back. Can push the boat forward quickly."

"Furthermore, this thing is placed vertically, which can allow the boat to sail in all directions, unless the headwind cannot drive. Such a large effect can be achieved with such a simple method. This design is really amazing and ingenious."

The more Huang Xiujun analyzed it, the more he was amazed. He turned around directly, bowed to Zhang Yanjin and said, "Dare to ask Zhang Lushi, how did you design such an amazing thing? What's the name of this thing?"

As soon as his actions and words came out, there was another whisper in the court.Huang Xiujun is the most proficient in all kinds of crafts. He is only busy studying architectural matters on weekdays, and ignores other things, let alone human relations and other things.

But now that he actually asks Zhang Yanjin for advice in such a respectful manner, one can imagine how powerful this design is.

Everyone's eyes focused on Zhang Yanjin in unison, some were amazed, some were confused, and some were suspicious.However, these people are capable among capable people, so naturally they would not speak at this time, and they all quietly waited for Zhang Yanjin's next words.

"I really don't dare to do it." Zhang Yanjin took a step forward, supported Si Youlang and Huang Xiujun said: "Si Youlang is serious, this design was actually thought up by chance when my brothers and I were going out to play."

Seeing Huang Xiujun vowing not to give up without asking the end, and everyone in the court looking at him, Zhang Yanjin smiled wryly and said: "One day when we were rowing on the lake, the sun was too strong, but we were greedy for playing. A big plantain fan was placed on the boat to cover the sun. Originally, I just wanted to have a shady place, but I didn’t want a gust of wind to blow by. , I found that installing such a thing on a ship can make the ship go faster, so I named this kind of thing a sail." This originally appeared in the fifteenth century, but it doesn't exist now, so he just I can say it casually.

"So it's like that, I've been taught." Si Youlang and Huang Xiujun sincerely admired him.

He is a person who admits death and only likes to study construction technology, but whenever he meets someone who is better than him, he will go forward to ask for advice, and he is not ashamed to ask.At this time, Zhang Yanjin's detailed explanation made him suddenly enlightened, and he felt ashamed when he thought that he often took a boat, but he didn't discover the magical effect of the sail.

"My Majesty, there are many oars on this boat. When rowing, everyone can take turns rowing. If everyone rowed together, this boat will definitely be able to break through the water and move forward without fear of heavy rain. The shape of the boat is like a duck or a swan. For rowing on the water, I think Zhang Lushi must have been inspired by the rowing posture of water birds. This design allows the boat to move forward stably and quickly under the influence of water and wind. This design is really amazing. Heavenly workmanship." Huang Xiujun explained to the emperor again.

After finishing speaking, he changed the subject, pointed at the rudder of the ship and said, "It's just that I don't understand something, such as here, please ask the emperor to ask Zhang Lushi to explain it for everyone."

"Zhang Yanjin, come and tell everyone." The emperor was very happy at this moment.The ever-rising flood in Zhongzhou can be said to be a serious problem in his heart, like a sharp sword hanging above his head, but he never thought that Zhang Yanjin would solve it so easily this morning.

"My Majesty, this is the rudder of the ship, which can control the direction of the ship."

Zhang Yanjin took the blueprint and pointed to the rudder at the stern to show the emperor and Huang Xiujun: "Ordinary boats use oars to control the direction of the boat, but this boat has a lot of water, and there are many people rowing. It is obviously impossible to control the direction of the ship, so I designed the rudder at the stern. We all know that if you row the boat at the stern, you can easily change the direction of the ship by simply changing the blades. The rudder makes use of this point .”

His finger moved down slightly, pointing to the rudder blade under the boat and the lever connected to the rudder wheel, and said: "These three things are connected together, when the rudder turns, the rudder blade will also turn, and in this way, a water flow will be formed at the stern of the boat." , and then form a certain water pressure, although this pressure is small, but the rudder of the ship is at the stern, and the distance from the center of the ship, that is, the center of the ship, is very far. There was a huge pressure build up amidships which caused the ship to change direction."

Speaking of this, he was afraid that his explanation would not be clear, so he gave an example: "It's like carrying two buckets of water is very heavy, but it is very easy to carry two buckets of water on a shoulder pole."

After being silent for a while, Huang Xiujun said excitedly: "Baron Zhang is really smart, I admire you!"

Excited, he cupped his hands again and said to the emperor: "Please also ask the emperor to let Baron Zhang come to work in the Ministry of Industry and work for the emperor!"

The emperor had exactly this intention, this ship was designed by Zhang Yanjin, it would be best if he was there when it was being built.

Zhang Yanjin has tossed about things these days, and found that Zhang Yanjin is really a talent in the Ministry of Industry. Since he is a rare talent, he should naturally keep it for his own use. Of course, the most important thing is that Zhang Yanjin stood up today. Pleasing to the eye, I want to give him a promotion.
