Datang Happy Landlord

Chapter 150;
Chapter 150 The Kitchen Knife
Li Yu, who was thinking alone, was interrupted by someone who came,

"I don't know why Lang Jun is looking for this old man?"

A loud voice resounded through the main hall.

"Oh, so it's Patriarch Gongshu, please sit down,"

The two exchanged a few simple greetings before taking their seats.

Li Yu uttered all his plans and ideas, and asked someone to bring a pen, ink, paper and inkstone, and drew more than a dozen blueprints of waterwheels.

Medium and large waterwheels that do not rely on electricity at all are vividly displayed on the paper.
Through non-stop drawing, Li Yu's level is now equivalent to the entry level of art colleges,
At least this Tang, apart from him, there is no other person who can make such a three-dimensional painting.

"Windmills, overturned cars, the old man has seen a lot of them, Mr. Lang, this kind of thing is new, do you still use people?"

Gongshuban's attitude towards professionalism is very serious, and he doesn't raise his head when he is talking here.

Li Yu hurriedly introduced; "The overturned car left by the predecessors is too heavy.
And it needs manpower to drive it, which is troublesome and laborious. A certain person saw some patterns from Lu Gong's secret method, and after careful consideration and modification, it became like this.

Patriarch, please see, a certain person called this improved overturned cart a water drum cart,
It rotates by itself with the water flow, adding different numbers of bamboo tubes to draw water from low to high, and its effect is much greater than that of the overturned cart left by the previous people.

This kind of drum car can be made of bamboo or wood into a large vertical wheel, which is supported by a horizontal shaft and can rotate freely.

Many small bamboo tubes or small wooden tubes are installed obliquely around the wheel, and the big wheel is placed on Heliu, so that the lower part of it is immersed in the water.

Under the impact of the water flow, the water tank car rotates by itself, and the small tube hanging obliquely around the wheel, when submerged in the water, is filled with stream water and rises with the rotation of the wheel.

Because the opening of the cylinder is inclined, when the bamboo rises, the water in the cylinder will not flow.

When the vertical wheel rotates 180 degrees, the small tube has been lying flat on the highest point of the vertical wheel, and then the mouth of the tube is in a downward position.

The water is released from the high place into the gutter and flows into the farmland on the bank.

This kind of bobbin car that rotates continuously and makes noise all night plays an important role in solving the irrigation in areas with high shore and low water and turbulent water flow.

In one day and night, more than [-] mu of fertile land can be irrigated, and the effect is very great. It is true that people do not have to irrigate, and the fields have the benefits of constant ripening.

If the water is plentiful, the bamboo tube can be removed to make it idling without printing water, so as to prevent waterlogging.

When needed, the bamboo tube can be fixed again to irrigate by itself.

A certain man removed all the pedals and ox pulls of the predecessors, and then asked the blacksmith to create a curved bearing that is more convenient and flexible to rotate, and installed it in it.

Insert the horizontal shaft that runs through the center of the entire waterwheel into the crank bearing,
This makes the rotation more sensitive and reduces the resistance by half.

Gongshu Pan frowned and asked, "What is Qu Bearing? I've never heard of it?"

"Oh, just use two large and small rings, and put steel beads in the middle. In this way, a certain man made a big spinning top for brother, and asked someone to bring it. The patriarch will know it at a glance."

Waiting for the servants to bring Qin Huaidao's big spinning top, the two of them went out together and came to the concrete road in Zhuangzi.
Li Yu turned the top away, and with a whip, the top started to spin crazily, fast and steady,

Li Yu's childlike innocence rose, "Patriarch, please see if this spinning top with steel balls is more powerful and faster than the usual spinning top."

"Snapped"

"Snapped"

As Li Yu spoke, he crackled the whip, causing Qin Huaidao to dance and chirp excitedly beside him.

"Although this kind of iron ball can increase the speed, if it is soaked in water for too long, the corrosion will be serious,

I'm afraid it has to be replaced every year, and it's too troublesome. It's better to use oxen to pull it, people to step on it, and the pressure of the water flow is enough.

"Patriarch, please come with me. All the blacksmiths have already gone home. Fortunately, there are ah, otherwise no one will make it,"

The two of them came to the blacksmithing yard while talking. The normally bustling blacksmithing yard was empty for a long time.
Li Yu picked up a horizontal knife worn by ordinary soldiers, yamen servants, and city gate military lords in the corner, and took out a shiny kitchen knife.

"Patriarch, please look, this is a horizontal knife forged by an ordinary blacksmith,

This is what I researched, the new forging secret method, adding several Taoist alchemy things, and adding some carbon,

This new kitchen knife is more than ten times more powerful than the fine iron forged by Bailian. "

After finishing speaking, Li Yu didn't waste his tongue, and directly chopped the kitchen knife in his hand towards the horizontal knife,

There was a sound of a clash of swords and swords, and the horizontal knife snapped in response. Gong Shuban, who was looking straight ahead, widened his eyes.Open your mouth wide open.

After a brief astonishment, Gongshuban took the kitchen knife from Li Yu's hand, inspected it carefully, and found that there was no curved edge or notch on the blade of the kitchen knife. He couldn't help but be very surprised.

Then he said with a serious expression; "Your Majesty, this method should not be easily shown to others. In my opinion, it is better to entrust it to the Supreme."

(The Tang Dynasty often called the emperor privately, everyone, official family, and supreme.)
Gongshuban continued to talk to himself; "With this kind of weapon made of refined steel, our Han soldiers will no longer be afraid of the fierceness of foreign races, and there will be no more dead souls on the battlefield.

The border guards have this thing in their hands, isn't it like adding wings to a tiger? The king is required to report it to the imperial court, so how can he hide it for personal gain? "

"Don't worry, the patriarch, I am also a Han Chinese, and I am also a citizen of the Tang Dynasty. The soldiers of the three armies are mighty, and the court soldiers are strong and strong. This is what I think in my heart.
It’s not that I don’t want to present this method to the imperial court, it’s that this method has only been formed for two days, and Agui and I just figured it out the day before yesterday. Let the patriarch first take a look at it.
Now that the new year is approaching, why not hand it over to my two uncles after the Yuanzheng in the next year, and present it to the imperial court, so as to strengthen the army? . "

"No, sir, don't delay. You can send people to Chang'an to deliver the letter today. This is a powerful weapon for the country. It will be sent to the court as soon as possible. The old man is also at ease.
If the gentleman refuses, please forgive me for not agreeing to the renovation of the granary and the construction of the river embankment. "

Seeing Gongshuban's appraisal expression, Li Yu could only agree,
Unexpectedly, this ancient man had such a deep-rooted thought of loyalty and patriotism, and regarded the country so important.Especially the Gongshu Ban, who was extremely stubborn.

Since Li Yu agreed, he stopped talking nonsense.

"Come on,"

A servant came in from the yard and stood with his hands down. "The villain is here, what are your orders at home?"

Li Yu handed over the kitchen knife, picked up the cut-off horizontal knife, and hurriedly sent the two things to Chang'an City, Duke Yi's mansion, and handed them over to his uncle. Don't neglect it, just leave. "

"promise!"

The servant promised and left.

"Patriarch, can we continue talking about the river improvement now?"

Gongshuban looked at Li Yu with a smile,

"Dashan, sir, but you have an assignment, how dare you refuse to serve him?
If Lang Jun has any other ideas, you can tell them all, and the old man will help you with all the strength of your family. "
