The black-bellied lady of the demon king of another world

Chapter 960 Underground passage
"Yes." Xiao Yu brushed her dripping hair with her hand, a layer of white gas soon appeared on her hair, and then her hair was completely dry. "Our city is very well built, whether it is the height or thickness of the city wall, or the towers and crenels that look out, they are all perfect, but what we build seems to only focus on the ground and ignore the underground."

Yan went on to say: "Our Dragon City is built on the hillside, and there is only one small gate at a time, except for the largest gate, which is used as a temporary passage. But because the water city is empty, there are a total of Four city gates. But our terrain is almost the same, and the inner city of Dragon City may be relatively higher. However, we used bamboo pipes for the sewer part we built at the beginning. It is possible to meet our survival needs on weekdays. , but now the rain is too sudden, we are worried that the rain will be too heavy, causing the sewer to be blocked, if the snow on the mountain melts and the rain hits together, our city may be completely submerged."

Among the people here, only the freshwater people who are not afraid of flooding feel indifferent.

However, the lips are dead and the teeth are cold. At this time, the Tamsui people will not stay out of the matter. Otherwise, if there is any danger in Shuicheng in the future, Longcheng will naturally stand by and watch.

Xiao Yu looked up at Jie and Poser, "When you built the water city, although you also got a bamboo pipe for the water, you did it to drain the daily sewage. It can be said that the underground network of the water city is more efficient than that of the dragon city. Fragile."

Kai had already opened his eyes, and he frowned and said, "The bamboo pipe that goes into the water?"

"Yes!" Xiao Yu took out the bamboo paper and charcoal pen from the space, spread the bamboo paper on the table and began to draw. "The above is where we live. The sewers are those bamboo pipes. Some lead to our domestic water, and some lead to the toilet to discharge sewage. Of course, there are also those on both sides of the water channel, which are used to melt snow and rainwater. Those that can flow directly into the huge lake in our inner city, we call that lake Longhu.”

Yan looked at the expressions of everyone, and said: "Because the foundations of the city walls and houses have been completed, and many pipes cannot be changed. Therefore, we hope that the three parties will cooperate to directly dig drainage channels underground. Give up those bamboo tubes."

Jie didn't like to hear such trivial matters, so he yawned a little complicatedly, "Just tell me what you need to do!"

"We need to dig sewers underground, just like building a house on the ground, and dig these sewer pipes into cylindrical shapes, so that we will have a larger population in the future, and we don't have to worry about water and drainage problems." Xiao Yu explained while drawing a picture .

"This sewer...is used for drainage?" Possel's eyes flashed.

"It's not just that." Yan looked at Possel, "This is a huge project built underground. Those wide pipes can drain water and store things in them, and they are all over the city...Of course, they can also pass through Somewhere outside the city."

At this time, not only Yan and Poser, but others also naturally understood. Jie lowered his head and thought for a while, then looked up at Yan, "You want to build a village underground?"

Nia and Kai were a little excited. Living on the ground is good, but living underground is safer, isn't it?

"It can't be said to be an underground village. That will happen in the future. From the current point of view, it can only be called a secret underground passage." Xiao Yu looked at everyone with bright eyes.
