Dahan first prince

Chapter 79 Not Good Enough
Liu Ying's short ten digits made Yang Chengyan's eyes widen!
Seeing Yang Chengyan's expression of a little surprise, but also vaguely uncertain, obviously thinking quickly, Liu Ying couldn't help but secretly smiled.

——The soil in the upper reaches of the fixed river seems to be a bit out of reach for Liu Ying, who was just a child of a poor family in her previous life.

But it is a coincidence that in the first life, before the big exam, Liu Ying lived with her parents in the countryside of the Northwest...

Liu Ying still clearly remembers that when she was a child, the village still had a system similar to "conscription", that is, each farm family sent a strong man to participate in voluntary labor every year during the slack season.

Occasionally, it is the excavation and laying of roads;
But in the Northwest, where water resources are scarce and agriculture is extremely important because of poverty, most of the labor labor is digging small canals in the countryside.

In that life, after turning 15 years old, Liu Ying couldn't bear to let her elderly father and elder brother with a slight disability go to serve in the military, so she began to take on this responsibility for her family.

From Liu Ying's 15 years old to Liu Ying's final exam, four years before and after, every year after autumn, Liu Ying participated in the forced labor on behalf of her family, digging and building canals!
In later generations, the Northwest was dry and hot, and water resources were extremely scarce. Therefore, during the excavation and construction of canals, there were very strict requirements for 'water seepage prevention'.

At the same time, the Northwest was very poor at that time, and did not have the conditions to spend a lot of money to lay plastic anti-seepage layers under the canals, or directly build canals with concrete.

So at that time, in order to prevent the canal water from seeping into the bottom of the canal before it flowed downstream, the cadres in the township would order Liu Ying and other young men to lay rocks at the bottom of the canal.

That period of memory, to Liu Ying at this time, can be described as far away.

But that carefree, full and happy memory only needs a little introduction to be brought back again.

After recovering from the sweet memories, Liu Ying found that in her mind, she already had a method to fix the soil in the upper reaches of the river.

--rock!
In most times, it can be called the cheapest, least technically required material, and has no side effects!
According to Liu Ying's idea, in the northwest of the previous life, by laying rocks on the side and bottom of the canal, the water in the canal could be prevented from seeping down.

Since the canal water can be prevented from seeping downwards, how can the upstream sediment not be fixed?
The upstream sediment is compacted and fixed by stones, so how can the downstream be blocked by river sand and silt?
And at this point in time, Liu Ying, as the crown prince, has much better materials and power to mobilize than the Great Northwest of later generations...

While Liu Ying fell into memory, Yang Chengyan was also thinking.

At that moment just now, Yang Chengyan felt a faint light flash in his dim mind!

But before Yang Chengyan could catch it, the spot of light disappeared in a flash.

"Heavy things..."

"Compaction..."

Murmured twice as if his eyes were numb, Yang Chengyan finally "returned his soul", looking at Liu Ying, his eyes were full of enthusiasm for unknown things!

"Dare to ask my family!"

"What should be used to press the soil in the upper reaches of the canal?!"

Even if Yangcheng Yansheng was afraid that Liu Ying would be frightened by him, he tried his best to suppress the excitement in his heart, but it was not difficult for everyone in the hall to see: Prince Liu Ying, I am afraid that he has come up with something extraordinary!
All of a sudden, everyone in the hall couldn't help holding their breath, and their suspicious eyes switched back and forth between Yang Chengyan and Liu Ying.

Seeing that Liu Ying pondered for a while, looking at Yang Chengyan, there was a faint determination in her eyes.

"stone!"

"Crush it with a stone!"

"With the huge weight of the stone, you only need to stick it close to the bottom of the canal, lay a hundred catties of boulders and tamp it down, and the soil in the upper reaches of the canal can be solidified!"

Hearing Liu Ying's words, Yang Chengyan froze in place, his brain was running fast, and he reconstructed the picture Liu Ying had drawn.

Stones, more than a foot long and wide, slid down along the wooden boards on the side of the canal; one by one, slaves and officials stood at the bottom of the canal, and the three of them worked together to lift the stones and lay them regularly on the bottom of the canal.

As one stone after another filled the bottom of the canal as tightly as possible, the entire bottom of the canal was weighed down by a thousand pounds.

The bottom of the canal, which had to be hammered and compacted, was only compacted by the laying of stones; coupled with the pressure of the stones, the sediment at the bottom of the canal would no longer be washed away by the water...

"wrong······"

"Stones are smooth, not square, and have their own gaps; the sand in the canal will still be washed away a little..."

Talking to himself, Yang Chengyan nodded to himself.

When Yang Chengyan's numb eyes, like walking corpses, reappeared the brightness of a "biology", Yang Chengyan's face was full of admiration for Liu Ying.

If stones are laid on the bottom of the canal, there will indeed be gaps, and some sediment will still be washed away!

But even so, it is much, much better than laying nothing, just compacting the soil at the bottom of the canal and letting the soil be washed away by the water!

"At home!"

Full of excitement, Yang Chengyan looked at Liu Ying's gaze, and a little bit of light suddenly ignited!
"I believe that what the family said is indeed a perfect strategy for consolidating the upper reaches of the canal!"

"Although there are gaps in the rocks, the upstream sediment may be lost and the downstream sediment may be blocked, and the blockage of the river can be greatly eased!"

"If the Zhengguo Canal implements this method and paves the bottom with stones, the downstream silt may be cleared every five years, and the upstream soil will be filled every ten years!!!"

Listening to Yang Chengyan's excited chant, all the people in the hall widened their eyes, casting unimaginable gazes at Liu Ying.

Prince this is...
In just a few words, subvert the world's water engineering skills?
Just when all the officials in the hall were dreaming and struggling to digest the "perfect plan" that Yang Chengyan said, they saw Liu Ying on the imperial steps, only smiling and shaking her head.

"Dig the downstream every five years, fill the upstream every ten years..."

"I think it's still too frequent; it only makes the court wasteful, and the people are exhausted."

When she said the phrase 'not enough' without changing her face, Liu Ying smiled and turned her head to the side, looking at Yang Chengyan with a playful face.

"There are gaps in the stone because it is not square."

"Could it be that the current Shaofu is powerless to obtain the Founder's Stone?"

Hearing Liu Ying's words, Yang Chengyan couldn't help being stunned again.

But this time, Liu Ying didn't give Yang Chengyan a chance to brainstorm.

"Whoo~"

Sighing a little, Liu Ying stood up, walked down the imperial steps, and came to Yang Chengyan with a smile.

"I heard that although the construction of Chang'an City has not been settled for a long time, since the fifth year of the Han Dynasty, the Shaofu has started to cut stones to obtain stone bricks with a length of two feet, a width of two feet, and a thickness of one foot. use?"

As she said that, Liu Ying couldn't help smiling gently, stretched out her hand to the gate of the palace, and made a gesture of 'please' to Yang Chengyan.

"Gu, I want to go to the place where the stone bricks were cut in the Shaofu, and see the stone bricks for myself!"
