There is a word called Shu dog barking day.

It refers to the humid air in the Bashu Basin, surrounded by mountains, and the water vapor of the plain is not easy to disperse. Dogs don't see the sun very often, and they bark strangely when they see the sun.

Shuzhong is well known to be rainy, and the rainy season is long and continuous every year, especially in June, July and August, and there are heavy rains from time to time.

Lin Siyi and the others were catching rats, and they didn't want a drizzle, of course, it had no impact on the immortals, and they continued to act as planned. As a result, the drizzle continued for three days, and on the fourth day, the rain suddenly increased.

Night, small town.

The work of eliminating the rodent infestation is nearing completion, and the effect is remarkable, locking the black-haired rats within 60 kilometers and killing them all. The small city belongs to Dujiangyan City, and the government urgently transferred a batch of grain to stabilize the situation, but there are still many people who defect to relatives and friends, so that the city is empty.

The street lights were dim and the rain was pouring down, Lin Siyi and Fei Qin walked from the long street, and their bodies were not wet.

The two of them looked at the clammy and depressed streets, and they both inexplicably felt a sense of restlessness, as if the matter had not yet ended.

"It's raining a lot, it's been raining for a few days, isn't it?"

"Well, just this part of Dujiangyan, there is not much rain in Rongcheng. ”

"I'll go back tomorrow, but I don't think it's right. ”

"I'm the same, but I can't tell. ”

People who are advanced in cultivation will have early warnings on a whim, and they are vaguely aware of them, but they can't see the situation clearly. The two walked and walked until they reached the outskirts of the town, and their hearts became more and more irritable.

Fei Qin suddenly said: "Let's go to the Minjiang River to have a look?"

Lin Siyi was stunned for a moment, and then said, "It's okay." ”

As he spoke, the two flew for dozens of miles to the bank of a wide river.

The Min River flows through Maowen, Wenchuan and Dujiangyan from north to south, and then passes through Xinjin, Pengshan, Meishan, Qingshen, Leshan and other places, and finally flows into the Yangtze River, which is the most important water system in the Bashu Plain.

And the famous Dujiangyan is built in the Minjiang River.

Everyone knows that Dujiangyan was built by Li Bing and his son, mainly composed of three major parts: fish mouth, flying sand weir and treasure bottle mouth, as well as ancillary projects such as Baizhang embankment and herringbone embankment.

Its existence directly makes Shu "drought will lead water infiltration, rain will plug the water gate, water and drought from people, do not know famine, there is no famine year, the world is called Tianfu also." And continued for more than 2,000 years, and it is still in play today.

When it comes to Dujiangyan, the Chinese people are proud.

Lin Siyi and Fei Qin went to the riverside and looked through the heavy rain curtain, and the water level rose rapidly due to the heavy rain for several days. The Minjiang River is surging from the north, the water head is several feet, and there are many houses and fields on both sides of the river.

The water irrigated the holes, and the disturbed rats had nowhere to hide, so they had to climb over the dam and cross the ridge to enter the people's house, and there was another wave of rat infestation. However, these are normal voles, which can be exterminated by the official organization and mobilizing the masses.

The two looked at it for a while, and simply flew into the air to see the whole picture.

This time it was very clear, the terrifying waves rushed to Dujiangyan, the water suddenly decreased, and the dense channel system like a spider's web divided the flood into two, two, four, and four...... When you go to Rongcheng again, there is no harm.

The two of them landed on the waterbank of the fish's mouth, feeling the roaring and rushing turbidity waves gently diverging under their feet, as if the dark giants had been subdued, and for some reason, a strange feeling of nostalgia suddenly surged.

"A thousand years of achievement!"

"It's a thousand years of work!"

…………

"It's raining again. ”

Hundreds of kilometers away on Ba Mountain, Xiao Zhai stood on the Yunyu Tower, looking at the lingering night rain, and sighed lightly.

At this time, Yunyulou is no longer the three thatched huts, but the three-story wooden building. After accumulating prestige in the early stage, the Bashan faction finally ushered in some changes, the most obvious is the infrastructure, although it is not as magnificent as the Shenxiao faction, but it is not so shabby.

And behind her, three little turnip heads were taking the exam.

Gu Xiaofei went out to open the sect, and Fang Yuan and Shui Lanshao stepped up their cultivation to impact the human immortals as soon as possible. Qing Buzi has reached the innate realm and is training outside.

These three are newcomers who have not been in the field for a few years, Mi Bei, Mei Yibo and Zhong Wenjin.

Mei Yibo's original name is Mei Xiaokang, what kind of ghost name is this, Xiao Zhai was very disgusted, so he changed the road number - well, it was drawn by lot.

Their homework is to answer some Taoist scriptures or Taoist allusions, brush and rice paper, and work neatly. As a scholar, Xiao Zhai is also demanding of his disciples.

"Master, I'm done. ”

After a while, Mi Bei took the lead in putting down the pen and staggered over.

Xiao Zhai glanced at it and said, "Yes, it's better than last time." ”

"Hee-hee!"

Mi Bei was very happy to receive the compliment, so she accompanied the master to watch the rain.

The little man just crossed the railing, only showing his head, trying to look out, and suddenly said, "Master, it's also raining over there in my house, it's been a few days." ”

"Your house, oh ......"

Xiao Zhai remembered that the child's hometown was in a town in Dujiangyan.

"But I'm not afraid, I've been down before, and it's all fine. Mom said that because of the dam, it would protect us. ”

"What dam?"

Mei Yibo is from Xiaoxiang and also came to hand over the papers.

"It's Dujiangyan, it has been built for thousands of years, and it has never been broken. Mibei's face was full of pride.

"I haven't made a decision for thousands of years, so I don't believe it!" Mei Yibo pouted.

"It's true, it's never broken!"

The two children began to argue, and finally naturally let Xiao Zhai judge.

She didn't bother to coax the child, and threw it downstairs one by one, but her heart turned, the world is proud of Dujiangyan's unresolved mouth for 2,000 years, in fact, it has also been decided, but it is not the main project.

In 1933, a major earthquake struck Diexi in the upper reaches of the Minjiang River, causing a landslide that cut the Minjiang River into large and small lakes. Later, the lakes burst, and the flood that poured into the mountains and seas went down with the river, and the waves were dozens of zhang high, which directly washed away the head of the Dujiangyan canal.

Further afield, there was a flood in the Tang Dynasty, and the irrigation section also broke the embankment and damaged the fields, causing a catastrophe.

Guankou is a town, named because it is located at the mouth of the Dujiangyan irrigation canal. Du Fu has a poem "Stone Rhino Xing", which roughly records the flood.

"How did you write this poem?"

Xiao Zhai thought about it, oh yes.

"You don't see Qin Shishu is too guarded, and the carved stone is made of three rhinoceros.

Since ancient times, although there is a method of disgust with victory, the river naturally flows eastward.

The Shu people have boasted for a thousand years, and the overflow is not close to Zhang Yilou.

This year, the irrigation of the mouth is damaged, and this matter may be ashamed. ”

…………

Lin Siyi and others didn't know this poem, and after they returned to the Taoist Academy, they reported it truthfully to the teacher.

With Zhang Shouyang and Chao Kongtu retreating into the background, he is now the third abbot, the slippery dead fat man, the master of feng shui and formations - Wang Ruoxu.

He is an innate cultivator, and he has not even reached the human immortal, but his prestige is quite high. The formation system in the world was almost single-handedly sorted out and reshaped, and all the monks in the world benefited from it.

And he has a sleek personality, is old and sophisticated, and handles all aspects very cleanly. Of course, he also knew that he was probably the last transition, and the next stick would be handed over to his disciples.

said that Lin Siyi finished the task and came to the back mountain alone, asking to see the elder.

Facing Lu Yuanqing, Zhang Shouyang and other immortals, he described his discomfort in detail and asked the other party for advice.

After listening to the details of his trip to Bashu, Lu Yuanqing asked, "Do you know what caused the rat infestation?"

"I don't know, it just suddenly erupted from Qingcheng Mountain and quickly spread to the township. ”

"Qingcheng Mountain is a place of cultivation, how can there be an outbreak of rat infestation?" Zhang Shouyang also asked.

"We went to the Heavenly Master Cave to pay a visit, and the abbot said that that time coincided with the Jiao Festival, and Qingcheng Mountain set up a seven-day ritual for seven days, and would give away a hundred talismans every day. ”

Lin Siyi paused and continued: "Qingcheng Mountain has a magic circle blessed by the Daoist Academy, and the side doors and left roads are not allowed to enter, and evil things are also not allowed to enter. So the people flocked to the city, hundreds of thousands of people, but nothing happened. But if you want to talk about strange things, there is one thing. ”

"Come on!"

"There is a believer named Wu Chao, who begged for seven days in a row, and then met Yuan and Taoist people at the foot of the mountain. The Taoist took pity on his filial piety, sent a homemade amulet to dispel illness, and instructed him to hang it at the head of the bed.

Who knew that when Wu Chao went home, he hid the talisman in the wall. Three days later, the old mother died violently, and soon the old father also died. The Heavenly Master Cave went to investigate, and found that the talisman had become a disgusting thing, so he felt that someone had done something to break it on the spot, and brought it back to the temple to be destroyed.

After more than ten days like this, there was no clue about Wu Chao's matter, and one night, the rat infestation suddenly broke out in the mountains. At that time, the situation was critical, and I didn't think much about it, but later the Heavenly Master Cave also said, maybe it had something to do with the disgusting thing.

The disciple also guessed that the man's target was not Wu Chao, but Qingcheng Mountain. The thing that wears away from victory must be very strange, and it entered the mountain through the body of Enlightenment Mako, and it did not cause a warning from the magic circle. ”

"This rat infestation, how much is the damage to the Heavenly Master Cave?" asked Zhang Wumeng.

"No Taoist was killed, but there was no grain in stock, and all the farmland was destroyed. ”

"Oh?"

Zhang Wumeng twisted his long hair and said, "If you have a grudge with the Heavenly Master Cave, this revenge is too light." ”

"How is Shu now?" Zhang Shouyang asked again.

"The rat infestation has been eliminated, continuous heavy rain, the Minjiang River has skyrocketed, but it can't rush Dujiangyan. ”

“……”

For a while, several people were secretly thinking. In this series of events, there is a faint line running through it, and it is vaguely impossible to capture.

After half a ring, Lu Yuanqing and Zhang Shouyang raised their heads at the same time, their faces shocked.

"Senior brother, have you made any discoveries?" asked Sikong Toad.

"There are indeed some contexts ......"

Lu Yuanqing nodded, and said a secret story about the mixture of history, myth and practice.

It is said that there was a man named Turtle Ling in Chu State, who fell into the water one day and drowned, and his body went up the current and rushed all the way to Pi. No sooner had they recovered him than he was resurrected.

Emperor Wangdi (the one who became a cuckoo bird after death) heard that there was such a strange thing, so he called the turtle spirit, talked very speculatively, and made him the prime minister of Shu.

Turtle Ling led the people to control the water, and gradually gained prestige, and Emperor Wangdi gave him the imperial throne.

After the turtle Ling took over the throne, he was known as Emperor Cong, also known as the Enlightened Emperor. Later, the Enlightened Dynasty moved the capital to Rongcheng, which had the earliest prototype of the city.

Later, Qin destroyed Shu, and Zhang Yi carried out large-scale construction of Rongcheng. It is said that when Zhang Yi built the city, he repeatedly failed to stand, and suddenly saw a big turtle spinning around, and the witch said: Build it according to the turtle's line. And they were established.

In order to commemorate Zhang Yi, people built a Zhang Yi building on the side of the Minjiang River, with more than 100 feet, facing the mountain and overlooking the river.

And the person in charge of the construction is called the public loss class, that is, Luban.

In the period of King Qin Zhao, Li Bing and his son built Dujiangyan, and Shu became a country of abundance, with no floods for thousands of years. As a result, when it came to the Tang Dynasty, there was a sudden flood, which burst the embankment and destroyed countless fields.

According to the records of the Taoist classics: after the public loss class built the Zhangyi Building, a wooden man was buried in a secret place, and a grain of rice millet was placed on each side of the burden to maintain the balance of the wooden man, and left a sentence: The wooden man does not fall, and the water is not close to Shu.

In the year when the water was sent to Guankou, before the flood, a large-scale rat plague broke out in Shudi, and all the food that could be found was eaten......
