Early the next morning, the wild dog was brought back by Huozi refreshed, and the anger on the whole person disappeared, which made Li Zhang also relieved, but for the sake of insurance, he also forbade the wild dog to go underground during this time.

However, Li Zhang didn't let the wild dog go, but the wild dog secretly went underground at night, because he felt that he was already well, and it was already early summer, and it was likely to encounter a heavy summer rainstorm during this time, so he wanted to draw a blueprint of the underground pit before the city of Tokyo was flooded.

Li Zhang also later found out that the wild dog secretly ran out at night, but after seeing that the wild dog did not appear before the situation, he also slowly put his mind at ease, and it was with the efforts of the wild dog that the drawings of the underground pit became more and more perfect, especially the pit in the northwest area drawn by Li Zhang, which has been explored by the wild dog clearly, in addition to the official sewer, even some of the pits dug by the ghost beggars themselves have been recorded by him.

With this drawing, Li Zhang finally put his mind at ease, now everything is in place, there is only a heavy rainstorm owed, although the heavy rain in the capital every year will bring a lot of trouble to the people, and sometimes it will cause death, but compared to the ghost beggars, the threat of floods is much smaller, but Li Zhang is a little worried, in case the weather is too dry this year to rain, I am afraid it will have to wait until next year.

However, Li Zhang's worries were obviously a little unnecessary, and at the beginning of July this year, the sky in Tokyo City was immediately filled with dark clouds, which seemed to collapse the sky, and the water of the Bianhe River and the Jinshui River also began to skyrocket, and experienced people had begun to move their belongings to higher places, so as not to soak in the water.

In fact, Kaifeng as the capital has great defects, the most important thing is that it is too close to the Yellow River, and at this time the Yellow River has become an above-ground river, and the Bianhe River and the Jinshui River that flow through Kaifeng are also connected with the Yellow River, so as long as the Yellow River rises, the capital may face the danger of being flooded, Zhao Kuangyin wanted to move the capital to Luoyang, but unfortunately it did not make the trip because of the opposition of Zhao Guangyi and others.

A few days ago, heavy rain fell on the upper reaches of the Yellow River, which caused the water level of the Yellow River to rise, and as a result, the water level of the Jinshui River and the Bianhe River also rose.

It is worth mentioning that the sewers of Tokyo City are actually connected to the Bianhe River, and some sewage will also be discharged into the Bianhe River, and with the surge of the river, the river water is poured into the sewers, and some low-lying places have even appeared to accumulate water, and now the weather is also gloomy, if this rainstorm falls, I am afraid that it will be another flood, so the government has also begun to organize the relocation of people.

Li Zhang looked up at the gloomy sky, and immediately quickened his pace towards the vertical arch hall, and in his arms, with the road map of the pit that the wild dog had explored, now he was going to see Liu E in person, and use this drawing to persuade her, and take this opportunity to send troops to clear out the ghost beggars.

"See the big lady!" After Li Zhang entered the main hall, he also saw Liu E very quickly, and he also bowed at the moment.

"Do you still know to come to see the mourning family?" Liu E glanced at Li Zhang at this time and said, since Li Zhang stepped down as a firearms supervisor, he has not entered the palace during this time, coupled with the rumors that Li Zhang has fallen out of favor in front of Liu E, naturally more people have affirmed their speculation, but Liu E and Li Zhang have no way to explain this matter.

"Big lady forgive me, in addition to being busy with money during this time, I am also preparing another thing, you can see it now!" Li Zhang said and took out the drawings in his arms, and then sent them to Liu E with both hands.

Liu E also opened it very casually at this time, but when she saw the things on the drawing, her face couldn't help but change slightly, and then she looked at it carefully, and finally she said to Li Zhang with a solemn face: "Where did you get this picture, and is the content on it accurate?" ”

"Aunt Qi, the content on the drawing was drawn by someone I sent someone little by little, and the content is absolutely accurate!" Li Zhang also clenched his fists at this time and said.

Hearing Li Zhang say this, Liu E also showed an excited expression, the drainage potholes under the capital extend in all directions, and these potholes were not dug at the same time, some even existed before the establishment of the Great Song Dynasty, so although there are some drawings of underground potholes in the official mansion, they are not complete, and many of them are missing, which is one of the reasons why the imperial court has not been able to clear out the ghosts.

At that moment, Liu E ordered someone to bring the drawings of the underground pits in the capital collected in the palace, and compared them with Li Zhang's court, and found that Li Zhang's was obviously much more detailed, not only the pits recorded by the government were on it, but also there were many pits that were not recorded, and even the high and low positions of some pits were recorded clearly.

After confirming that this drawing was correct, Liu E couldn't help but show a solemn expression, and then pondered for a moment before speaking: "You took this drawing out, do you want to completely eliminate the ghost beggars in the capital?" ”

"Yes, the ghost beggars in the capital have been harmed for many years, and the government has no way to take them, and the reason why they are at large is mainly because of the potholes that extend in all directions underground, as long as they drill into the ground, the people outside have no way to take them, but I found that every summer when the capital rains heavily, the potholes in the southeast will be filled with water, if there is a big flood, then most of the potholes in the underground can not survive, only the higher areas in the northwest area are without water, At that time, the ghost beggars will definitely be concentrated in the northwest area, and the pothole routes in this area are all on this drawing. Li Zhang also showed an excited look when he said this.

"No wonder you want to come to the mourning family at this time, the Bianhe River and the Jinshui River have skyrocketed in the past few days, and the weather is also gloomy, you are planning to take this opportunity to wipe out all the ghosts!" When Liu E came here, she also showed a contemplative expression.

Ghost beggars are indeed a major scourge in the capital, and not only ordinary people are victimized, but even some powerful families are not spared, and ghost beggars not only rob money, but most importantly rob children and women, which is also the place that everyone hates the most, it can be said that as long as the capital mentions ghost beggars, there is no one who does not hate, but the government has no way to take them.

However, now Li Zhang's proposed method is very effective, the flood will limit the activity space of the ghost beggars, and the route of the underground pit has also been identified, as long as a few thousand people are sent down at that time, it should be able to solve the biggest scourge in the capital, and this will also become one of Liu E's political achievements during his reign.
