After the words fell, Yan Qingyao finally looked up at her.

She was a dark and thin little girl, very short, with her hair meticulously combed, tied into a ponytail at the back of her head, and her prison clothes dirty, which matched the appearance of a prisoner.

The only thing that attracted him was that her dark eyes were lonely, like an ancient pool that had been silent for thousands of years, only occasionally flashing a ray of streamer and broken gold, which was really beautiful.

After a while, he beckoned, and Gao Lin brought a map of Kanyu and put it on the desk, and he spread it out: "The Jiaming River flows south from the west side of the Zhongling Plain, and it is an authentic ground hanging river for the entire Zhongling Plain.

The whole topography of the Zhongling Plain is inclined to the southeast from the Yulei Mountain in the pass of the Jiaming River, with a very large slope and a drop of more than 500.

Whenever the Jiaming River floods, the Zhongling Plain is an ocean, swallowing fertile land and invading people's livelihood; In the event of a drought, it is thousands of miles of red land, and there is no harvest.

It is imperative to control the flooding of the Jiaming River, not to mention, November is the rainy season, and we don't have much time. ”

After the words fell, he raised his eyes to look at Lu Tao, and several other people also looked at her.

The wind blew from outside the curtain, bringing up the prison uniform on her body and swaying a faint wavy line, and the whole person stood quietly like that, ordinary but giving people a sense of vastness, at this time, he spoke: "Allow you to come forward." ”

Lu Tao was worried that it was difficult to explain without a map, and he couldn't help but be surprised when he opened his mouth, but he didn't refuse, and walked directly to the desk, pointing to Kanyu and saying:

"From here, a dividing weir was built with a water dividing fish mouth, dividing the Jiaming River into two. The outer river is the main stream of the Jiaming River, and the inner river supplies water for irrigation canals.

The mouth of the treasure bottle was built here to control the throat of the flow of the inner river.

The construction of a flying sand weir between the mouth of the fish and the mouth of the treasure bottle plays the role of overflow and sand and pebbles.

When the flood comes, the excess water of the inner river overflows from the top of the weir into the outer river. At the same time, a large amount of river pebbles will be discharged into the outer river, so as to reduce the siltation of irrigation channels. ”

"It's a good idea, but it's hard to implement." A deep and deep voice sounded, with a bit of elegant taste.

Lu Tao turned his head to look, and saw a middle-aged man with a feather fan scarf bowing slightly to her, and then said: "The place where you said the mouth of the treasure bottle, the left is Yulei Mountain, and the right is the pile, where the rock is hard and difficult to excavate.

If you want to break this mountain for diversion, you need to beat it for many years, and you can't dig this mountain in five or six years. ”

Several other people nodded secretly, worthy of General Yan's think tank, and he could always point out the key points at the first time.

"That's right," the goatee man nodded, echoing, "what do you know about hydrogeology, little yellow-haired girl?" Go back, and don't talk nonsense. ”

Lu Tao's eyelids narrowed slightly, and a ray of cold light was fleeting under his eyes.

"Eh, Mr. Lu, don't say that." Xing Yijiang shook the feather fan in his hand with a smile and said, "She is a child, if she can think of this, she must also be involved in books, congratulations." ”

Lu Hai's face changed slightly, but the other party was General Yan's number one think tank, and he was defeated, so he had to arch his hand and compliment: "What Mr. Xing said is true." ”

Xing Yijiang smiled, turned to look at Lu Tao, and shook the feather fan gently, "Little girl, what do you think?" ”

Lu Tao also smiled back: "Then what if you use fire to burn the rocks, and then pour cold water or vinegar on it and then excavate?" ”

As soon as these words came out, Xingyijiang feather fan shook lightly, and after thinking about it again, he couldn't help but look at Lu Tao in surprise.

Finally, he looked at Yan Qingyao, and it happened that the other party also looked over. He nodded slightly, and the feather fan shook gently: "Childe, this plan is feasible, it can make the rock easy to crack in the thermal expansion and cold contraction, and reduce the difficulty of excavation." ”

"How long is the duration?"

"Doing it at the same time can shorten it by three years."

"Can it be done in two years?" Yan Qingyao muttered softly, and then raised her eyes to look at Lu Tao who was standing in front of the desk, she was standing quietly like that, still with a smile as light as water on her face. He raised his eyebrows slightly: "What's your name?" ”

"Lu Tao."

"But what do you want?"

"Out of slavery."

As soon as these words came out, everyone turned their heads to look at her.

Yan Qingyao took the finger of the pen, for him, getting out of slavery is not a big deal, a matter of words.

Looking at the little girl, a hint of interest flashed in his eyes: "Yes." When you arrive at the penal colony, the paperwork will be delivered to you. ”

"Thank you." Lu Tao breathed a sigh of relief in his heart, and then spoke: "Can you give me a map of the Lingnan Exile Zone?" ”

"Bold!"

Before Yan Qingyao could speak, Lu Hai immediately shouted, raised his eyebrows and said, "The border defense map is also what you can ask for a little girl?" ”

This person has an enmity against himself?

Lu Tao's eyebrows frowned slightly, but he didn't speak.

She wanted a map, not a map of the border, but there was a difference between the two, and the difference was very big.

The former is irrelevant, like a modern world map, anyone can take a copy; The latter is crucial, belonging to military maps, and is not available to non-key figures.

Lu Hai fastened such a hat on her head, which was tantamount to saying that she had rebelled.

But he didn't speak, because none of the people present were fools, and it wasn't that they couldn't tell the difference between a map and a map.

Sure enough, as soon as Yan Qingyao waved his hand, Gao Lin took out a map and gave it to Lu Tao.

"But what else do you want?" Yan Qingyao spoke, his voice low and slightly magnetic.

Lu Tao shook his head: "It's gone." "If you want it again, it's that she doesn't know how to lift.

"Gao Lin."

"Childe."

"Send her back."

"Yes."

Looking at the back of the two leaving, Yan Qingyao's eyes narrowed slightly, his deep gaze tightly locked on the thin figure, and in his pupils, the deep black vortex was spinning rapidly, and after a long time, he spoke: "How is this son?" ”

Xing Yijiang's hidden eyes under his eyelids narrowed, and he withdrew the faint gaze that fell on the girl, with an elegant expression:

"In ancient times, Ganluo worshiped Prime Minister Zuo at the age of twelve, which shows that some people are innate with wisdom and are close to demons, and they can't be envied."

In one sentence, Lu Hai's tone was set, and even Lu Hai, who wanted to sing the opposite, had to swallow. The others were shocked, looking at the people around them, this sentence seems to be too high?

Rao is Yan Qingyao, when he heard Xing Yijiang's words, a trace of surprise flashed in his eyes, he turned his head and looked at Xing Yijiang.

The latter seemed to know what he meant, but he didn't explain, just smiled lightly: "Childe, let's see in the future." ”

On the other side, after Lu Tao was sent back to the tent by Gao Lin, he was greeted with a worried greeting from the whole family.

Especially the Liu family, looked at her from head to foot at 360 degrees, and finally hugged her tightly: "Doudou, where have you been, my mother is about to worry about you." ”

Lu Tao gently patted Liu's back and comforted: "Mother, I'm fine, I just went out for a walk." ”

"Doudou, you don't say anything where you go, look at your mother, you're crying urgently." Chen (Chen Daju - the daughter-in-law of the big house) spoke quietly.

"That's not it." Lu Xueqing (the head of the second room) also diverged, and after confirming that she was fine, he sat back and muttered: "I'm worried about death." ”

"Sister Doudou, have you seen my mother?" At this moment, the voice of Lu Qingyou (the eldest son of the fourth room) interjected.
