When the herald ran up the hill again, he saw Li Dan talking to Zhou Qin, who had just returned, in front of the Tianwang Palace, and Xiao and Tan were also there.

"Defense, Chief Ma let me tell you, that group is camped at the foot of the opposite mountain!" Summons report.

"Got it, Chief Ma and the former battalion continue to monitor the same place, as long as they don't come to attack, we won't move!"

"Huh? Got it! The herald was stunned, and hurriedly agreed to go down.

"So, is there really such a river?" Tan Zhongxuan rubbed her hands excitedly and asked Zhou Qin.

"Yes, the river is wide and the current is not fast, but it is not shallow!" Zhou Qin turned back to Li Dan and said:

"Some of the brothers I left behind swam to the other side to look for the boat, and asked for more details by the way. There are also some people who followed Second Brother Zhu to check the southern river. ”

"You think the water can lead you?" Xiao Wanhe interrupted him anxiously.

"I can lead!" Zhou Qin nodded affirmatively: "I have taken a closer look, it is estimated that it has rained upstream, the water is a little muddy and earthy, and the water level is about the same as that from the shore."

We found a suitable place not far from the shore to make a dam, divert the river water, and open the gate when we needed it. ”

"Wouldn't it be nice to dig it up, why do you want to make this trouble?" Tan Zhongxuan waved his hand, Zhou Qin did not answer, and looked at Li Dan with a little embarrassment on his face.

"The valley is sparsely populated, but there are still inhabitants. It's easy to dig, but it's not easy to control the flooding. Li Dan said.

"That's what defense says." Zhou Qin nodded:

"I heard from the locals that there are five north-south valleys on the south bank of this river, the fourth valley is the Dongtang under the Lingyan Temple, and the fifth valley is on the right side of the mountain.

In previous years, the river flooded these valleys during the rainy season, but now the water is not so big, and we dig it up, and the water all pours into the fifth valley, which not only floods the inside, but also makes the downstream water starvation.

This season is the season of water, and we can't afford to lose the people. So I thought, just drop the brake at about the same time, so that it is easier to control. ”

"You don't work!"

A few people looked back and saw that it was Xiao Shami.

"Yo, little one, why not?" Tan Zhongxuan caught him with an arrow and came back with his arm:

"Say a way and let you go, otherwise it will be the crime of delaying the military aircraft and opening your ass!"

Xingwu pursed his lips and broke free from him, squatted down and posed with a stone for a while, pointed and said:

"The little adult is going to flood the Seventh Army, right? And when the thieves had entered the mountain, the waters rushed from here into the valley, and they were all kings. But ......, you didn't know there was a waterfall here, did you?

Below is the apricot blossom pond, which has been washed out by a lot of water for many years. The water gathers here, and when it spreads out again, the bandits will either run away or kill us all! ”

Everyone was stunned. "Damn, how can there be a deep pool?" Zhou Qin hurriedly asked, "Is what the little master said true?" ”

"Monks don't speak."

"Do you know how far the waterfall is from the mouth of the river?"

"The little monk thinks that there are seven or eight miles of land, anyway, it takes a long way to walk from Xinghuatan to the mouth of the river!"

"You walked by?"

"I'll go with my brother." Xingwu suddenly panicked, looked around and whispered:

"Senior Brother Mao used the water in the pool to make fruit wine ....... I didn't say anything, so you don't hear it! ”

The crowd laughed.

"Okay, okay, please come and say that I have something to ask."

"Oh." Xingwu agreed, and fled quickly.

"Well, if it's like what he says, it's a bit tricky!" Zhou Qin squatted on the ground, frowned and stared at the stone placed by Xingwu, and said:

"This has to be released in advance, if you wait for the enemy to get closer, I'm afraid it's too late! And if the amount of water is small, it won't work, so who knows how long it will take to fill the pool?

Oops, I didn't expect there to be such a play, it's terrible! He slapped his thigh hard in frustration.

Li Dan also squatted down, his fingers moving along the line dug out of the sand to indicate the river.

Suddenly, I heard a deep voice behind me say, "Listen to the little junior brother's words, but the defense is looking for me?" ”

Looking back, a tall and thin young man, holding a crockpot in his left hand and carrying one in his right hand, stood a few steps away with his head tilted.

This person is the "half" of the three and a half people mentioned by the abbot before, his name is Shi Mao, and he is regarded as practicing with his hair in this temple, so he does not tie his hair in a bun, but only ties his long hair with a cloth strap at the back of his head, like a horse's tail.

"Oh, Brother Shi, it's the defense looking for you, come, come!" Zhou Qin had a good impression because he was busy picking herbs and helping Master Ba treat the wounded, so he got up and greeted him.

"This ......, you guys are in the military, it's not appropriate to go down, right?" Shi Mao pointed to the ground and said.

"Brother Shi's cultivators, how can they still pay attention to so many rules for speed?" Li Dan smiled and beckoned:

"It's okay to come here, I just want to ask my brother for something." When Shi Mao got closer, Li Dan asked, "Xingwu said that brother has been to Xinghuatan?"

We are waiting for a strategy to break the enemy, and we are about to attack by water, and I want to ask my brother about the geographical situation over there. ”

Shi Mao looked back a little crampedly, and said, "This kid is the fastest, and he will sell me sooner or later!" Then he nodded and admitted:

"Yes, I went down there, and I walked there a few days ago, and Xingwu learned from me how to get in and out of the back mountain.

However, there is very little water coming down from the waterfall now, and it is only dripping, and it is only after rain that the waterfall can be seen. ”

"Brother Shi, do you know how deep that pool is, and how much water it takes to fill it?"

"Wait," Li Dan stopped Zhou Qin: "You can slowly discuss the details with Shi Jushi." Brother Shi, the younger brother just wants to know, if the river is opened and the flood is flooded, can the entire valley be flooded? ”

"It's hard!" Shi Mao replied without thinking, then put down the crockpot in his hand, squatted down and pointed: "This river rises every year, but it never floods the downstream, why do you know the defense?" ”

"But because the flood water drains into the valleys on the south bank, there is no hindrance downstream?"

"Yes, but why is there no water in the valley and no change in the course of the river?"

"I can't store water, but because the water has gone through all the outlets? The river has not changed, but this one is unknown. ”

Zhou Qin is a water hero who knows the river best, but others can't answer the things he shakes his head.

"What Zhou Yingzheng said is partially correct, but you may not know that there are many caves in this mountain, and many floods will pour into the caves and drain away with the underground river.

If you're going to flood the valley, it's absolutely not okay if the amount of water is small. ”

"Huh? I missed it! Zhou Qin was taken aback. By this point, it was clear to everyone that the original plan would not work, and that a huge flood would have to be created to flood all the valleys.

"There is no valley on the other side of the mountain, the middle is concave, the surrounding is high, just like a plate, and it has a common name 'Shipan Valley'.

This name is related to my second question. Zhou Yingzheng, you can't tell you the reason why the river has not changed, let me tell you. ”

Shi Mao looked left and right, ran to the side and picked up two long stones to place at the confluence of the river and the valley.

"Oh, see it? The mountain trend here is mostly east-west, and the river is formed in the middle of the mountain gorge.

The embankment you see is not an ordinary embankment formed by the accumulation of soil, in fact, three feet of topsoil is peeled away, and the bottom is full of rocks. The surrounding mountains are earth at the top, gravel at the bottom, and rocks at the bottom.

The middle is low, and the surrounding area is surrounded by stones, isn't it a stone basin?

So the same is true of the embankment, which is just lower than the ridge you can see, and the seeds of the sediment that accumulate on the surface sprout into grass and shrubs.

That's why the river bank never collapsed when the flood overflowed in previous years! ”

He looked up at Zhou Qin: "It has indeed rained upstream in the past two days, not big enough!" Even if you pick up the topsoil, you can't dig the stones, the gap is limited, and the water leaking out may not be much.

In some places, it may be up to the thighs, and a little farther away you may only lose your ankles. ”

"It's over, what kind of embankment is there? If there are stones down there, this ...... I don't know what to do. Zhou Qin's face was full of disappointment, he originally wanted to take the opportunity to make a big contribution this time!

"Don't worry, in fact, Leader Zhou, if you want to make meritorious contributions, there are still ways."

"What's the solution?" Hearing him say this, Zhou Qin immediately pressed his hand on Shi Mao's shoulder: "If you have a good idea, I will donate twenty taels to the temple after it is completed!" ”

"Good, I am not here to kill, nor to ask for your sesame oil." Shi Mao laughed:

"I'm just here to preserve the ancient temple. After all, the bandits crossed the border, and the temple said that it would also suffer a disaster, and if it could retreat from the enemy to avoid disaster, it would naturally have to contribute to the next. ”

Speaking of this, several people urged him to hurry up and say a way.

Li Dan hugged his shoulders with a smile, seeing that he was holding the momentum and everyone's appetite was raised, before he opened his mouth leisurely and continued:

"The method of water attack does not hinder both. or draining water, or pooling water. Since there are stones below that can't be discharged, then naturally we have to find a way to gather. ”

Li Dan immediately teased: "But there is no such effort, the bandits will come when they say they will come, where can they wait for another rain?" ”

"Rain? No, no! Shi Mao shook his head: "In the past few days, the local sky has been clear, and there has been no heavy rain."

It is not to collect rainwater, but to use the water that is available in the river. ”

"Oh?"

"The river meandered southward for more than two miles, and when it reached a place called Tiger Rock, the terrain on both sides of the river became higher, and the riverbed quickly narrowed to less than one zhang and five feet, and the flow rate increased, and the waterfall that was one foot and two feet high was rushed down to the southwest."

Shi Mao gestured with both hands and finished speaking, and looked at Zhou Qin again.

"I see, you mean to build a dam here in Tiger Rock to make the river rise. If we open the embankment at Yuantouling and release water, the amount of water will be enough to fill the valley? ”

Zhou Qin patted her knees hard and became excited.

"Even if you can't drown people, it's definitely okay if you don't have a valley full of rivers and ponds. At that time, Zhou Yingzheng only needs to prepare a few bamboo rafts and boats, and the big thing is harmonious! ”

After Shi Mao finished speaking, he got up and said to Li Dan: "If there is nothing else, I will go down to change the dressing for the wounded."

Oh, there are two jars of home-brewed good wine here, you can taste it, but also hope to be merciful, and don't miss it out to the abbot master. ”

All four of them laughed at him, and they all got up and gave them away.

"This is a lovely person, and he left two jars of wine before leaving, which is interesting!" Xiao Wanhe shook his head and smiled, picked up the wine jar with one hand, and saw that there was a line of words on the paper on it: Take water under Xinghua Creek in the spring of March of the sixth year. "Yo, it's the year before last." He said.

"According to him, the waterfall in Tiger Rock is not high." Zhou Qin had no intention of this, and muttered to herself on the ground:

"The problem is that if we want to build a dam, when and how will the water be released on the Yuantou Ridge?

We don't have that many people, so if we build a dam, we have to go to 300 people, right? So how can you take care of Yuantou Ridge? ”

"It doesn't matter," Li Dan said: "It's good for you to leave Second Brother Zhu here, take two hundred people from the right camp and go, and trouble Brother Xiao to send one hundred brothers to follow, it should be enough to have these three hundred people to repair the dam."

Brother Xiao took 150 people from the left camp to join Second Brother Zhu, and if it was not enough, 100 people from the back camp were transferred to assist.

These two hundred and fifty people were responsible for digging the embankment, leaving 100 people to block and backfill afterwards, and the rest searched along the river valley in the direction of Xinghuatan.

Brother Tan, your remaining fifty brothers will defend Xishan, and the rest will set up bamboo rafts and rafts, and when the water rises, they will search for the remnants of the enemy in the valley and kill all those who try to resist. ”
