Dahan first prince

Chapter 81 Putting stone bricks on Zheng Guoqu!
"color!"

With a sudden applause, Liu Ying stepped forward with joy, ignoring the fearful figures of the craftsmen kneeling on the ground, and went straight to the stone, carefully sizing up the cut surfaces on the two halves of the stone!
Perhaps the crown prince came with all the officials and watched the whole process. The stonemasons were obviously a little nervous. The cut surface of the stone was not too smooth.

To be precise, it is two cut surfaces, one side is slightly protruding, and the other side is slightly concave.

But even so, the unevenness of the two cut surfaces is not very obvious, which is completely within the acceptable range.

As for the concave cut surface, even if it is a circle with a diameter of two meters, the concave part may not hold a ladle of water.

"color!"

There was another unrepressed applause, and Liu Ying turned sideways, only to see that the previous stone-cutters had knelt down on the ground in fear.

Seeing this, Liu Ying smiled gently, bowed her waist without hesitation, put her hand on the dusty, sweaty, muddy arm of one of the craftsmen, and warmed it up.

"You all have outstanding ingenuity and superb skills, and you have made great contributions to the state!"

"Come on!"

She shouted suddenly, and when a Lang official stepped forward, Liu Ying let out a joyful shout.

"Every craftsman who breaks stones today will be given one yi (jin) of gold and one piece of cloth!"

Hearing Liu Ying's words, the few craftsmen were obviously taken aback, and immediately kowtowed to thank the crown prince for his reward.

At this time, Shaofu Yangcheng Yan also came forward together with the courtiers and officials, and said with a little self-satisfied "modestness" on his face: "The craftsmen were a little bit inaccurate when unscrambling the stone today, so the stone is flawed... ·”

Hearing this, Liu Ying smiled indifferently, waved her hands, and turned to look at Yang Chengyan.

"Can the stone bricks that have been cut be viewed together with Gu?"

After seeing just now, these craftsmen cut a boulder in half, and can ensure that the cut surface is as flat as possible. Liu Ying has already figured out that in this generation, the length, width, and height all meet the standard. , and the six sides are generally flat stone bricks, how to get it.

——As before, divide the lying boulder into two through the method of "marking and nailing". Repeat this several times, and you can get several pieces with flat front and back sides, uniform thickness, and generally irregular Columnar slabs!

Then, the edge of the stone slab was cut off by scribing and nailing to obtain an approximately square shape, and then it was cut into square bricks of different sizes according to the size requirements.

In this way, the stones that were originally irregular and three-dimensional were cut into square stone bricks for the purpose of building the city!
Now that she knew how to obtain the stone bricks, Liu Ying didn't intend to waste time and continued to observe, but directly stated the purpose of her trip.

- Finished stone bricks!
Hearing Liu Ying's question, Yang Chengyan hurriedly bowed and waved towards the distance, then a square black stone brick was hugged by two craftsmen.

After the stone brick was gently placed on the ground, taking advantage of Liu Ying's time to look it over, Yang Chengyan couldn't help but introduce the brick in a low voice.

"At home."

"This square brick was cut by craftsmen from the Shaofu on top of the boulder in the sixth year of the Han Dynasty under the order of His Majesty to 'Build the Four Walls of Chang'an'."

"It is two feet long and wide, one foot thick, and weighs nearly three hundred catties; it can be used for laying the inside, outside, and roof of the city wall to strengthen the city wall."

Listening to Yang Chengyan's interpretation, Liu Ying only nodded slightly, and reached out to touch the four sides of the stone bricks.

It's not very smooth when you touch it with your hands, but overall, it's definitely a flat surface!
Even a rough surface is enough for laying the bottom of the canal, and there is no need to worry about obvious gaps between the stone bricks!

Thinking so, Liu Ying looked at all sides of the stone bricks again, and after confirming that they could all be regarded as planes, she stood up and clapped her hands.

"Now Shaofu, how many stone bricks are there?"

Hearing this, Yang Chengyan immediately bowed his hand.

"These stone bricks were all cut from the fifth year of the Han Dynasty, when His Majesty ordered his ministers to prepare for the construction of Chang'an."

"So far, the Shaofu has obtained such stone bricks with a length and width of two feet, a thickness of one foot, and a weight of three hundred catties. There should be 20..."

Yang Chengyan spoke so well, Liu Ying couldn't help counting silently in her heart.

"The stone bricks are two feet long and wide, and the bottom of the Zhengguo Canal is nine feet wide..."

After a little silent calculation in her heart, Liu Ying came to the result.

The bottom of the Zhengguo Canal is nine feet wide, and it takes 45 pieces to lay a row of two-foot-long stone bricks.

And Han Yili is 180 feet wide, and the stone bricks are two feet wide. One mile of river canal needs to be paved with 4 rows, a total of more than [-] stone bricks.

"20 yuan is only enough to lay five miles..."

With a leisurely murmur, Liu Ying's expression froze, and she looked at Yang Chengyan with determination.

"Write: The Shaofu has 20 official slaves in the Zhengguo Canal. Starting from tomorrow, the [-] stone bricks stored in the Shaofu will be transported to the upper reaches of the Zhengguo Canal!"

Hearing Liu Ying's words, the faces of the courtiers and officials who were watching froze, and they couldn't help but became puzzled.

Seeing that Yang Chengyan thought about it for a while, he hesitated and said: "The meaning of the family..."

Seeing Liu Ying nodded abruptly.

"Of course!"

"—Use 20 stone bricks to pave the bottom of the upper reaches of the Zhengguo Canal to consolidate the soil!"

Liu Ying's words immediately caused all the officials and courtiers around to freeze in place, stunned for a while!

Take the stone bricks used to build the city wall to lay the bottom of the canal?

"This this······"

"Looking at the past and present, have you never heard of it?"

While everyone was whispering, Yang Chengyan stood up anxiously and bowed to Liu Ying.

"At home."

"These 20 stone bricks were all obtained by the Shaofu in the past five years, and they will be used by Chang'an Construction in the future!"

"If this time, it is all used for the maintenance of the Zhengguo Canal, what will be used to build Chang'an in the future?"

"If Your Majesty blames the crime, how should I answer?"

Asking two questions with a bit of sadness, Yang Chengyan couldn't help casting his eyes for help to Xiao He, Zhang Cang and others beside him.

——This is today, when Liu Ying put forward such an unimaginable plan of 'pressing the soil of the canal with stones', Yang Chengyan paid a little respect!
If it is normal, knowing that Liu Ying has to save the stone bricks that Liu Ying has worked hard for the past five years in the Shaofu, and is going to use them to build Chang'an City, Yang Chengyan has to protect this point even if he is desperate. Wealth!

Seeing Yang Chengyan's looking for help, Xiao He thought for a while, and finally turned sideways suspiciously, looking at Zhang Cang beside him.

Seeing this, Zhang Cang pondered for a while before he stepped forward with hesitation.

"At home."

"What the Shaofu said is true..."

With a soft persuasion, Zhang Cang nodded slightly.

"To press the soil of the canal with stones, it is not necessary to use only stone bricks. Or can it be paved with slightly flat stones?"

"And now, the number of stone bricks in Shaofu is only 20, and it is only five miles long if they are laid at the bottom of Zhengguo Canal."

"The rest of the Zhengguo Canal's upper reaches still have to be paved with uncut stones..."

As he said that, Zhang Cang couldn't help but bow his hands heavily.

"Please go home, think twice..."
