Li Zhang’s manor is very big, and no one will find anyone who buried it casually. And even if it is discovered, it’s nothing. Anyway, they are for self-defense, but it will be a little more troublesome if the government finds out, so they simply dig a hole and buried it.

The next morning, Li Zhang and the wild dog rode away from the manor, but they did not go directly into the city, but stopped by the Bian River. Then Li Zhang pointed to the Bian River: "Wild dog, the capital is high in the northwest and low in the southeast, so the Bian River flows from the northwest to the southeast. When there are heavy rains every summer, the southeast corner of the capital is also the most likely to be flooded. Do you know all of these?"

Wild Dog nodded when he heard this. Although he didn't understand why Li Zhang told him, he still listened very seriously. In fact, Wild Dog is a very smart person, but it depends on whom he has to compare with. If he competes with Li Zhang, he always feels that he is too stupid, so whenever he encounters big things, Li Zhang will take the initiative.

"Now that we know the terrain of the capital, we can also learn from it that if the capital is flooded, the sewers in the southeast area will be filled with water. Unless it is a water ghost, there is no way to survive in it. At that time, the ghost beggars will definitely concentrate on the sewers in the northwest area." Li Zhang spoke again at this time.

The wild dog's eyes finally lit up when they heard this. The main reason why the ghost beggar is that it is difficult to clear the bottomless pits underground. Unless they send troops to block them, they will not be wiped out at all. However, if they can use floods, they can force the ghost beggar underground to a corner, which is much easier than before.

"But even if the ghost beggar is forced to the northwest area, this area is still not small, so I need you to clarify all the underground passages in the northwest area during this period and draw drawings. As for the method of drawing drawings, I will teach you. With this drawing, I can ask the court to send troops to clear the enemy. At that time, it will be much better than you alone." Li Zhang continued at this time. It is necessary to use the power of the court to clear out the enemy beggars, otherwise it will be impossible to complete it.

The wild dog was not stupid. He nodded heavily when he heard Li Zhang's words and said, "Okay, teach me, I will draw the drawings of the underground passage as soon as possible!"

Seeing the wild dog agree, Li Zhang was relieved. Then he took the wild dog along the Bian River to the capital, explaining the terrain under his feet to the wild dogs. In recent years, Li Zhang has been observing the terrain of the capital and places that are prone to floods every year when the rainy season comes, and these are all for the purpose of dealing with ghost beggars.

In fact, the method of flooding was the first to come up with Lu Wu. However, Lu Wu's idea was too simple and crude. He just wanted God to cause a flood to drown all the ghost beggars. But this obviously didn't work, but this also gave Li Zhang an inspiration, so he wanted to use the flood to force the ghost beggars to a fixed area, so that he could wipe them out in one fell swoop.

Of course, Li Zhang's method also has loopholes, that is, he must rely on the weather. If it doesn't rain or it rains too little, it will not achieve the effect he wants. However, according to Li Zhang's observations over the past few years, Kaifeng City at this time was much hotter and rainier than later generations, especially in summer, heavy rainstorms for several days are common, and the situation of flooding in the capital is even more common every year. This is also the main reason why the powerful people in the capital like to live in the northwest region. After all, the terrain here is high and they cannot flood their homes when they encounter heavy water.

After returning home, Li Zhang immediately taught the wild dog how to draw a map. In fact, he didn't know anything before, but there was information on this aspect in the computer, so he taught himself. There was also one good thing, which was a sports watch that could measure the altitude of the location. This was not measured by GPS positioning, but by air pressure. When Li Zhang discovered it, he took down the electrons inside, so there was electricity inside, but I don't know how long it would last?

With this watch that can measure altitude, the wild dog can know the height of his position. Although it may not be very accurate, it can also be recorded on the drawings for reference. Li Zhang also took out a map of the capital and asked the wild dog to record the key areas that need to be explored. In addition, Li Zhang also prepared several weapons, such as grenades, which he made himself, and their power is not smaller than those made by firearm monitors. It is extremely powerful in a narrow pit. Of course, he repeatedly reminded the wild dog to be careful when using it and never hurt himself.

After a period of preparation, the wild dog finally made perfect preparations and left home on a dark and windy night. However, just as the wild dog was leaving, Li Zhang suddenly called him, then untied his self-defense pistol from his leg and handed it to the wild dog and said, "You know how to use this pistol, and use it on your body for self-defense, but you have to return it to me when you use it."

The wild dog also showed a tangled look when he saw the pistol. He knew that it was Li Zhang's biggest weapon for self-defense, and even placed it under the pillow when he was sleeping. Now that Li Zhang handed it to himself, it can be said that he gave his safety to him.

"No, I have planes and sleeve arrows, which are not smaller than pistols, and the sound of the pistols is too loud, which may attract strong enemies." The wild dog hesitated and finally shook his head and refused.

Li Zhang also felt that it made sense when he heard this, so he did not insist anymore. He stepped forward and patted the wild dog on the shoulder and said, "Drawing pictures is second, the most important thing is your safety. Even if it doesn't work for a year, we still have the next year, but if you die below, we may not be able to find the body for you, so everything is your own safety!"

"I understand!" The wild dog nodded heavily, then turned around and left here. Li Zhang also watched his figure jump over the wall and disappeared into the vast night. This made him sigh. The wild dog's life experience was so pitiful that no one could match. His biggest wish was to kill all the ghost beggars. As his elder brother, he must also help him fulfill this wish!

That night, Li Zhang was worried that he had not slept all night, but in the early morning of the next day, the wild dog came back safely, which made him feel relieved. However, he found that there was a bloody smell on the wild dog, which obviously killed people again. However, Li Zhang didn't care. Anyway, the people who died were all ghost beggars underground. The court stipulated that those who killed the ghost beggars were not guilty, but could receive rewards, but Li Zhang and the wild dog didn't care about that little reward.
