The next morning, the wild dog was brought back by Kuozi with a refreshed look, and the anger on his body disappeared, which made Li Zhang feel relieved. However, to be on the safe side, he also forbidden the wild dog from going underground again during this period.

However, Li Zhang did not allow the wild dog to go, but the wild dog secretly went underground at night because he felt that he was already well and it was early summer now. He would probably encounter heavy summer rains during this period, so he wanted to draw the drawings of the anti-underground pit before Tokyo City was flooded.

Li Zhang later discovered that the wild dog was running out secretly at night. However, after seeing that the wild dog did not have the previous situation, he gradually felt relieved. It was with the efforts of the wild dog that the drawings of the underground pits became more and more complete. Especially the pits in the northwest area marked by Li Zhang had been clearly explored by the wild dogs. In addition to the official sewer, he recorded some pits dug by the ghost beggars themselves.

With this drawing, Li Zhang finally felt relieved. Now that everything is ready, he only needs a heavy rain. Although the heavy rain in the capital will cause a lot of trouble to the people every year and sometimes cause human lives, compared to ghost beggars, the threat of floods is much smaller. But Li Zhang was a little worried. If it was too dry this year and it would not rain, he might have to wait until next year.

However, Li Zhang's concerns were obviously a bit redundant. Just in early July this year, the sky in Tokyo was immediately filled with dark clouds, as dark as if it was about to collapse the sky. Moreover, the waters of the Bian River and Jinshui River began to soar. Experienced people have begun to move their homes to a higher place to avoid soaking in water.

In fact, Kaifeng has great flaws as a capital. The most important thing is that it is too close to the Yellow River. At this time, the Yellow River has become an on-ground river. The Bian River flowing through Kaifeng and the Jinshui River are also connected to the Yellow River. Therefore, as long as the Yellow River rises, the capital may face the danger of being flooded. At the beginning, Zhao Kuangyin wanted to move the capital to Luoyang, but unfortunately, it was not carried out due to the opposition of Zhao Guangyi and others.

A few days ago, heavy rain fell from the upper stream of the Yellow River, which caused the water of the Yellow River to rise. As a result, the water surfaces of the Jinshui River and the Bian River also rose. Although both rivers have embankments, because the water rises too fast, the river surface and embankment surface are about to be level.

It is worth mentioning that the various sewers in Tokyo are actually connected to the Bian River, and some sewage will also be discharged into the Bian River. As the river water surges, the river water flows back into the sewer. In some places with low terrain, water has even occurred. The weather is also gloomy now. If this rainstorm comes, it may be another flood, so the government has begun to organize the people to move.

Li Zhang looked up at the gloomy sky, and now he also accelerated his pace toward the Chuigong Hall. In his arms, he was carrying a path map of the pit found by the wild dog. Now he wanted to see Liu E in person and use this drawing to convince her, and take this opportunity to send troops to eliminate the ghost beggars.

"See the Grandma!" Li Zhang entered the hall and soon met Liu E, and immediately bowed.

"Do you still know how to come to visit the Ai family?" Liu E said at this time. He said that since Li Zhang stepped down as the Firearms Prison, he had never entered the palace for a while. In addition, there were rumors that Li Zhang had fallen out of favor in front of Liu E. Naturally, more people confirmed their speculation, but Liu E and Li Zhang could not explain this matter.

"Grandmaster, I am not only busy with money business, but also preparing another thing. You can tell at a glance!" Li Zhang said as he took out the drawings in his arms and sent them to Liu E with both hands.

Liu E also opened it very casually at this time. As a result, when she saw the things on the drawings, her face changed slightly. Then she looked carefully. Finally, she said to Li Zhang with a serious face: "Where did you get this picture? Is the content on it accurate?"

"Your Madam, the content on the drawing was drawn bit by bit by bit by bit, and the content is absolutely accurate!" Li Zhang also bowed his fists at this time.

When Liu E heard Li Zhang say this, she also showed an excited expression. The drainage holes underground in the capital are well connected, and these holes were not dug at the same time. Some of them existed even before the establishment of the Song Dynasty. Therefore, although there are some drawings of underground holes in the government, they are not complete, and many of them are missing. This is also one of the reasons why the court has been unable to clear out the ghost beggars.

At that moment, Liu E ordered people to take the drawings of the underground pits in the capital collected in the palace and compare them with Li Zhang's court. It turned out that Li Zhang's book was obviously much more detailed. Not only were the pits recorded by the government on it, but there were also many pits that were not recorded, and even the heights and low positions of some pits were clearly recorded.

After confirming that the drawing is correct, Liu E couldn't help but show a solemn expression, then pondered for a moment before speaking: "You use this drawing to completely eliminate the ghost beggar in the capital?"

"Yes, the ghost beggars in the capital have been harmed for many years, and the government has no choice but to do anything about them. The reason why they are free from the impunity is mainly because of the pits with all kinds of underground connections. As long as they drill underground, the people outside can do nothing about them. However, I found that every summer when the capital is raining heavily, the pits in the southeast will be filled with water. If there is a major flood, most of the pits underground will not survive. Only areas with higher terrain in the northwest will have no water. At that time, the ghost beggars will definitely concentrate in the northwest area, and the pit routes in this area are all on this drawing." Li Zhang also showed an excited expression when he said this.

"No wonder you are coming to Ai's family at this time. The Bian River and Jinshui River have soared in the past few days, and the weather is also gloomy. You are planning to take this opportunity to catch all the ghost beggars in one go!" Liu E also showed a contemplative expression when she arrived here.

Ghost beggars are indeed a major disaster in the capital. Not only are ordinary people victims, but even some powerful families are difficult to escape. Moreover, Ghost beggars not only rob money, but the most important thing is to rob children and women. This is also the place that everyone hates the most. It can be said that as long as the ghost beggars are mentioned in the capital, no one will hate them, but the government has no way to deal with them.
