"No, I've figured out what's going on over there. "In the night breeze, a clear voice came from the sky.

Before the words were finished, the Great Elder Linghu of the Holy Hall, who had not been seen a moment ago, had already stood firmly opposite a few people, for this white-haired young man who came from the sky like a shock, Qin Tianjian Yang Chunfeng, the surrounding palace maids and eunuchs, and several important ministers behind Qin Mu were all shocked, and Emperor Xuanyuan and Prime Minister Qin Mu had no different faces.

Qin Mu hurriedly asked, "May I ask the Great Elder, how is the situation over there?"

Great Elder Linghu said: "I just dived on the top of the tower, and after feeling the earthquake, I rushed to it as soon as possible, and the main change over there was that the Nanling Mountain Avalanche broke a huge gap nearly a kilometer wide. Now, there is a huge amount of Yuanjiang water roaring and rushing, pouring into this big gap at a rapid speed, and even because of the rockfall and the change of the terrain itself, even the water in the lower reaches of the Yuanjiang River is flowing to that gap. Other than that, there is no other big change, which is that the river needs to be cleaned up. ”

Qin Mu said to a person beside him: "What is the terrain south of Nanling Mountain?"

Emperor Xuanyuan knew that this person was Li Luhai, the secretary of the Ministry of Works, a top expert in the construction of large-scale projects, and knew a lot about the geography of mountains and rivers within the empire.

The Imperial Ministry of Industry was a concentration of technical officials. At this time, it is the time for the Ministry of Industry to show its talents, so at this time, Qin Mu's other people can not be brought, but the Ministry of Industry must not be left behind.

Li Luhai looked around, saw the soil in the flower bed in the distance, and wanted to run over to get it.

"Do you want to make a sand table?" asked Elder Linghu.

"Yes. Li Luhai said respectfully, and added: "I will be able to make the topography and landform there soon, and it is also easy to explain, and the specific location and specific depth of the mountain collapse that the Great Elder said just now also need to be pointed out to me later." He didn't know the specific identity of the Great Elder Linghu yet, but he just shouted with Qin Mu.

Great Elder Linghu nodded, waved his hand to the ground, and the smooth ground within a radius of two meters in front of him that was tamped with a mixture of unique clay and glutinous rice became as delicate and soft as flour, but the people around him did not feel the leakage of any strength, and the ground did not shake at all.

"Do you need water?" he continued.

Li Luhai nodded stunned.

Soon, in a rockery pool a hundred meters away, a stream of water was like a long snake, extending rapidly from the void, plunging into the soft flour sand, which was affected by the invisible whirlwind, and spun and stirred for a few breaths, and when they showed their shape again, they had become a dough-like mud surface.

Li Luhai didn't have time to be shocked, so he jumped up and quickly played a game of pinching mud, and behind him there was a waiter from the Ministry of Works, who was also his important assistant, and he also followed him silently to cooperate.

Soon, a specific and micro topography was pinched out by him, and he asked his assistant to continue to refine those details, and he began to point to the sand table model to explain to Emperor Xuanyuan and Qin Mu.

He first pointed to a deep ravine that came from the north and went east, and said, "This is the Yuanjiang River." ”

He also pointed to an east-west mountain range on the south bank of the Yuan River that blocked the river from flowing south and was forced to divert to the east, and said, "This is Nanling Mountain." ”

Then he asked the Great Elder Linghu, "Where is the specific location and depth of the collapse?"

Great Elder Linghu thought for a moment, and shot out with a force, cutting a gap in the entire Nanling Mountain Range a little downstream of the corner, and said, "The location and depth are probably like this. ”

Li Luhai nodded, pointed to the south of Nanling Mountain and said:

"The terrain of the Tian Yuan Continent is already high in the north and low in the south, and the further south you go, the lower the terrain becomes. Nanling Mountain has an approximately elliptical canyon basin landform that is 80 kilometers wide from east to west and 230 kilometers long from north to south on the south side of this gap, and its lowest point is 932 meters lower than the water surface of the Yuanjiang River on the north side of Nanling Mountain, and on average, it is about 480 meters lower than the water level of the Yuanjiang River.

The location is treacherous, and there are not many people in normal times, only some hunters and medicine pickers set foot in. With the size and depth of this opening, and considering the rate and flow of the Yuan River during this season, the water of the Yuan River will accumulate in this canyon basin within five days, creating a huge deep lake out of thin air, and after that, the water level will overflow here, here, here, ......"

As he spoke, he pointed to eight or nine relatively low places in the sand table: "At that time, a large amount of Yuanjiang water will go south wantonly, and if the mountains are fragile in some places and this giant lake collapses, the regions of several states in the south will suffer from catastrophic floods, and the nearest prefectures and counties will even cause great casualties among the people, and the damage to heaven and earth and other losses will be incalculable." ”

Qin Mu hurriedly asked, "Then what are we going to do?"

Li Luhai said: "Fortunately, we have a five-day buffer period, in these days, if we can complete the following points, then we can not only surrender the disaster, but also be able to turn the harm into a benefit." ”

While pointing out the location of the sand table, he made suggestions: "First of all, we must organize people to immediately empty the obstacles blocked on the river, and try to let the water of the Yuanjiang River go along the river." Also, although this huge gap cannot be blocked, there are three places here and here that can be filled with rocks in large quantities, which can minimize the flow of water rushing into this canyon basin and buy us more time. ”

At the same time, he pointed to the low places around the canyon basin that he had just pointed out, and said, "This, here, and here, the gaps are relatively narrow, and the rocks on both sides are relatively thick, so you can organize people to block them."

There is a naturally developed river five kilometers to the south, and the terrain along the way is relatively low, so that people can clean it up and make it into a river, and the gap should be made as wide and low as possible, so that more water can flow out of here and reduce pressure on other places. And here, here, can also be drained out separately. ”

Li Luhai pointed out the specific treatment measures for each gap one by one, and said: "Finally, we must send a large number of personnel to inspect the situation in other places at any time, once it is found that there is a huge amount of groundwater gushing out, there are other dark passages, or other hidden dangers, we must report it in time, and then we will decide on the scene to determine the treatment plan, in addition, we must send people to search for and rescue those medicine pickers and hunters who are trapped in this canyon basin by the big water." ”

Qin Mu bowed his head and asked, "How many people are needed in total?"

Li Luhai said: "Because this is a race against time, every place has to be carried out at the same time, and it must be effective within a few days, so there are a lot of people needed, and I estimate that 140,000 people are the most appropriate, because the working environment is so big, no matter how much it can be arranged." ”

Qin Mu asked, "How many people can the Ministry of Industry gather in a day?"

Li Luhai looked embarrassed and said, "I can only gather 20,000." ”

Emperor Xuanyuan interjected: "I immediately ordered all the ruling army and the Erwang Battalion that the two kings are forming to rush there as quickly as possible, and the Ministry of Industry immediately prepared a plan and commanded personnel to rush to Yuanjiang Bay to converge, and there is still a gap of more than 30,000 yuan, you can get it together within one day and send it over." ”

Li Luhai breathed a sigh of relief and said: "The strength of these people is much stronger than our workers, if we can listen to all the commands, we can ensure that we can complete this task in time!"
