In fact, Don thinks too comprehensively, he is a lazy person, so he wants to do it in one step, but in fact, the construction of a city cannot be done in one step, and every time it is accompanied by technological innovation, there will be a re-construction process.

Now, for example, although he takes the discharge of domestic sewage into account, in fact, Ellington ...... No, even in the whole of Prandal, there is no water project, and the people's water is generally taken directly from wells or rivers, so the amount of domestic sewage discharge is very small, and the natural environment here can achieve a normal purification cycle.

Because of this, Donn's habit of living on Earth has caused him to be very uncomfortable now, but fortunately, his identity is a lord, so it is not his turn to let him fetch water......

Don is well aware of this, but he is already thinking about the water project, so he plans the underground drainage system in advance to avoid any further problems.

And the underground drainage system also has a little benefit, that is, it saves labor, because it is an underground project, so Don can completely do it himself, and use the earth magic to solve the problem of the drainage pipes by himself, without attracting the attention of the residents of Ellington.

While recalling the impressions of the earth, while drawing a plan, before you know it, the night has passed.

"This is the blueprint you made!?"

Fiona's eyes jumped up when she saw the plan that Donn had placed in front of her, and she looked at it briefly, not knowing how to describe her feelings.

Now she has only one feeling, and that is perfection!

That's right, Donn's plan for Ellington can only be described perfectly, whether it is the market, the neighborhood, the road, or the living area, the industrial area, and even the fire prevention, garbage disposal, etc., all taken into account, according to his plan, you can imagine how clean and tidy the city will be!

What shocked Fiona the most was the underground drainage system specially marked by Donn on the plan, and now in the imperial capital of Alinks, there have been craftsmen who have put forward this idea, but it has not been completely realized, because the amount of work is very large, unless a magician is asked to do it, but magicians are arrogant, where is he willing to be a craftsman who digs a pit?

In addition, the royal family wants to open up sources and reduce expenditure, and is unwilling to spend too much price, so this project has not been put on the agenda.

Fiona didn't expect Don to directly propose a perfect underground drainage system design, which not only has a clear and definite design for the sewage treatment method of each household, but also has a solution for the final sewage treatment method.

The craftsman who originally proposed the underground drainage system had the biggest problem with what to do with the sewage discharged, because the city was built on water, and the residents had to use river water and groundwater, so the sewage could never be discharged into the river, and it was precisely because this problem was not solved that the royal family did not make up their minds to start the project.

Don solved this problem?

"Eventually the sewage is discharged into the sump of the paper mill? And then what? ”

Fiona frowned: "You haven't told me what to do with the sewage discharged from the paper mill, if it is discharged into the river and eventually into the sea, I am afraid that it will not be long before the Naga will come to the door." ”

"Didn't I tell you?"

Tang En was stunned: "In that cesspool, I solidified a miniature portal and discharged the sewage directly through the portal. ”

Fiona was also stunned: "Portal? ”

"yes......"

Before Don could finish speaking, Fiona suddenly exclaimed and looked at Don with a shocked expression: "What are you talking about...... Portal!? What you put in the cesspool that day was a teleportation array!? ”

Tang En patiently explained: "It's not a teleportation array, it's a substrate that solidifies the portal spell, which is different from the teleportation array. ”

The teleportation array is a connection between two fixed locations, and the spatial passage is very stable, which can transport a large number of goods and lifeforms, while the portal spell is much more fragile and cannot be opened for a long time, and if the transportation volume is too large, it will collapse directly.

Knowing that it was not a teleportation array, Fiona was disappointed, before the Chaos Invasion War, Brandal's teleportation array layout method had been lost, and the few remaining teleportation arrays were also damaged in the two Chaos Invasion Wars, and now Plandar has completely no teleportation array that can work, it is said that the Star and Moon Tower Secret Law Association has been working hard in recent years to study the remains of the teleportation array, and wants to restore the ancient teleportation array technology, but unfortunately it has not been completed.

If Don even had the teleportation array technique, Fiona would have really wondered if he had come as a god.

Fiona casually asked, "But the portal also has a goal, where did you discharge all the sewage?" It won't cause any trouble, will it? ”

"Well, the portal is the Fire Elemental Realm, and the sewage will be evaporated when it enters it, so it shouldn't-"

"Whew! Whatever! ”

Fiona exclaimed, and sat on the ground with her ass crooked.

Don pulled her up, puzzled, "What's wrong?" ”

"You're still asking me what's wrong!?"

Fiona said angrily, "You discharged the sewage into the Fire Elemental Realm!? Are you crazy!? Are you trying to provoke a plane war!? ”

Although she has never studied magic, Fiona also knows that fire elementals are water-repellent creatures, and throwing dirty water on their world is undoubtedly provoking those short-tempered fire elemental creatures!

If they can't bear it anymore, they will go straight through the portal and kill them......

The picture was too beautiful for Fiona to imagine!

"Don't worry, it won't."

Tang En shrugged his shoulders and said nonchalantly, "I checked when I opened the portal, and there is a barren area of the Fire Elemental Realm nearby, and there are no Fire Elemental creatures. ”

"Preferably, if the fire elemental creatures do invade Purandal, we will be the sinners of Purandal......"

The expression on Fiona's face was uglier than crying, she really didn't expect that she would come up with such a whimsical thing without a sound with such a bold lord......

"Don't worry, although the fire elemental creatures are very short-tempered and water-abous, but the fire elemental realm is so big, they are probably more willing to live in a different place than to spend so much effort to invade Plandall."

Tang En spread his hands and said, "If it were you, would you stay there in the rain all the time when it rained?" ”

"Of course not."

"So, don't worry about that."

"But I always feel that your analogy is a little strange......"

"You can rest assured, the Chamber of Commerce has also been officially established, and now your focus is to urge the steel mill to be completed and put into production as soon as possible, and the other is to start the planning and reconstruction work of Ellington, and if any family is not willing to relocate, you tell me, and I will do their work."

Fiona sighed, sat back on the stool and said, "Don't worry, there will be no one who will not cooperate, after all, you are the lord." ”

Don had forgotten that the lord had absolute control over the people, and he was still wondering if he should give the residents some reconstruction subsidies, so he stopped when Fiona said this.

If he had spoken out about his subsidy thoughts, Fiona would have been furious again.

"But ......"

Fiona picked up the plan again, frowned, and looked at it: "I see that your plan doesn't seem to be complete, and the underground drainage system you made seems to have a supporting facility, why hasn't it been drawn?" ”

"Oh, that's a water project."

Tang En said casually: "This will have to wait before construction can begin, and this condition is not yet available." ”

"Water works?"

Fiona became interested: "What kind of project?" Can you tell me about it? ”

"Of course, you're my CEO."

Don smiled and briefly introduced the concept of water engineering to Fiona.

After listening to Donn's introduction, Fiona became excited again.

"Water works! Oh! Oh, my God! Your Lord! Are you really a god!? How did you come up with such a genius idea!? ”

Fiona just thought in her mind about the life of water flowing out of the house without leaving the house, just turning the switch, and she trembled with excitement, if it could really be like Don said, then how convenient life in Ellington would be in the future!

Residents no longer have to queue up at rivers and wells every day to fetch water, so how much valuable time can be saved every day for construction?

"Of course, I've always been a genius."

Don was very cheeky in acknowledging Fiona's compliment, and said with a smile: "Since copper is needed for water pipes, there are no copper mines in Ellington now, so we can only put it down for the time being." ”

Most of the water pipes on the earth use stainless steel pipes or PVC pipes, although ordinary steel pipes or cast iron pipes can also be used, but they are easy to rust, and PVC is a material Don doesn't know how to get out, stainless steel has no impression of what metal is plated, so it can't be made, so it can only be given up.

In addition to these, there is another very good option, and that is copper water pipes.

The inner wall of the copper water pipe is smooth, and it will not rust and scale after long-term use, which can avoid secondary pollution of water, reduce heat loss, and inhibit the growth of bacteria in the pipeline, which has stronger advantages than other water pipes.

Copper water pipes are not used on the earth because copper is more expensive and expensive and ordinary people cannot afford to use, and due to the special situation of Plandal, copper is a very cheap metal resource, so the use of copper water pipes is the best choice for Donn.

One of the biggest problems, however, is that no copper mines have yet been found in Ellington.

Even if Don wanted to buy copper ore, he didn't have that condition right now, because Ellington didn't have that much wealth to import copper ore now.

Therefore, after all things considered, the water supply project can only be put on hold for the time being, and then find a way to solve the problem after the reconstruction project in Ellington is on the agenda.
