From time to time, there were bursts of laughter in Don's bedroom, and the consequence of forgetting to cast the mute spell was that Tina and the others were too frightened by Don to come closer.

They also thought that Don En was sick with something, which caused them to look at Don En strangely for the next few days.

"I'm a genius!"

In the bedroom, Donn looked at the substrate in front of him, and did not hesitate to praise himself, if the narcissistic Carl was here, he would definitely have a common language.

On the substrate in front of him, the triple magic array that was activated by his magic power flickered with a faint light, and it was obviously operating very normally.

On the top of the substrate, there is a levitating thing similar to the ram of the previous stamping machine, but some raised patterns can be faintly seen at the bottom, and if you look closely, you will find that those patterns are exactly the same as the magic array on the substrate.

That's right, the solution that Don thought of was to stamp it.

Using the battering hammer, the lines of the magic array are stamped out on the substrate, and then evenly covered with magic dust, and a triple magic array is completed!

In Plandal, all magicians know whether a magic circle can succeed or not, and there are three factors: first, whether the magic circle is drawn accurately, second, whether the magic materials used in the drawing can withstand the power of the magic circle, and third, whether the magic source used can drive the magic circle.

Among them, the second and third are the best solutions, and what has always hindered the magician from learning and mastering the magic array is the first point, how to be accurate

Draw a magic circle.

On the earth, if you want to restore a beautiful pattern, the easiest way is to print it with a printer, and a little simpler, children know how to play with cartoon stamps.

Tang En can't get a printer now, the printer is much more complicated than the printing press, whether it is the input or output of the magic array data, it is a problem.

But according to the principle of the seal, it is completely fine to make this stamped version of the magic array.

The principle of the magic array is nothing more than that the magic power flows in a specific path formed by the magic material, and then produces a specific effect, the magic array engraved by Tang En on the ram is convex, and after being stamped on the substrate, it will form the same groove as the magic array, and it is absolutely accurate and has zero error, which can completely restore the magic array depicted by Tang En!

After that, things are simple, Don only needs to sprinkle magic dust in the groove, and then activate the magic array, the magic dust will solidify under the action of magic and fix it in the groove, and then only need to change to magic crystal to provide magic power, and the function can be perfectly reproduced. [e1]

"I'm a genius!"

Tang En once again praised himself, shamelessly taking this "patent" for himself.

After discovering that this idea could be realized, Tang En drew inferences from one another, and instantly thought of many other methods, such as combining the LOGO of the Datang Chamber of Commerce with the magic array to achieve real anti-counterfeiting functions, and even using this principle to directly realize integrated enchantment on mass-produced armor and weapons, and in the future, his army can completely popularize enchanted armor and enchanted weapons!

The success of this idea can be said to have completely opened Donn's train of thought, making him excited, with this method, he will use magic to realize other earth products in the future, and he will not have to worry about mass production at all!

The only thing that restricts his development is the supply of raw materials and the problem of population.

Raw materialsAt present, the best and cheapest material he can think of is steel, and the Brussels iron mine next to it can provide him with a steady stream of iron ore, as long as the production capacity of the steel mill can keep up, there is no shortage of primary civilian and military materials, and when the strength is strong in the future, military materials can be completely replaced with more excellent magic metals.

But before that......

"Population......

Tang En couldn't help but sigh, population is always a big problem, not to mention the population here in Ellington, even if the entire Illus Empire, the population is actually only equivalent to a medium-populated province in China on the earth, only about tens of millions - you know, the Illus Empire is a country that once unified the human world after the Chaos Invasion War, but now it has fallen to this point.

And these tens of millions of people are scattered all over Ellus, and it is too difficult for Don to absorb the population from other places, unless there is a complete change here in Ellington, so that everyone can know about Ellington's existence and let them go here on their own initiative.

Donn has no doubt that Ellington will one day become the hottest place in Irruth or even in all of Brandal, but that will take a long time to develop.

"Well, let's plan before we do that......"

Don pinched his eyebrows, a little headache.

He hadn't learned anything like urban planning, and planning for urban construction had never been anything to do with a fart like him, but just because he hadn't studied it didn't mean he hadn't heard of it.

There are many things that need to be paid attention to in urban planning, whether it is the spacing, layout, lighting, or greenery, as well as the width of the road, the pre-planned development period, etc., these Don can guess without learning, even if he doesn't understand anything, just rely on the memory of living on the earth

It's also much better than Ellington's brainless mess right now.

The reason why Ellington is still relatively dirty and messy now is because there are few people, and if it is developed in the future, if there is no corresponding treatment method, I am afraid that it will soon become medieval Europe, full of filthy feces and sewage.

Tang En just thought about the consequences for a moment, and couldn't help but shudder, and shook his head vigorously.

Planning, must planning!

Don took out two pieces of parchment, the paper he made is not very durable now, it is no problem to be toilet paper and newspaper, and the recording is still a little worse, so it is better to use durable parchment paper for this kind of plan.

"The first is the division of buildings...... Separate the industrial area from the living area, and there should be a green belt in the middle to separate the ......"

Donn groaned as he drew a rough map of what is now Ellington on parchment, and even the surroundings. This one is a reference map, and the other one is a planning map.

Although the so-called industrial area in Ellington currently has only a steel mill, a charcoal mill and a lumber yard under construction...... Or maybe the mint candy workshop and the soap workshop next to the lord's house? However, Tang En felt that it was better to plan ahead, so that the development of the industrial zone and the construction of the living area could be separated from each other in the future.

In addition, considering the increase of population and the expansion of the city in the future, Tang En made the living area and the industrial area completely parallel and separated, and the development of the two was expanded outward, and did not affect each other at all.

"Well, we also need to take into account the transportation problems of residents to work in the future...... Reserve a transverse passage at intervals......"

Donn muttered as he drew two horizontal avenues on the plan.

"Although the population is not large now, it will be a central area in the future, and the road traffic must be reserved for more spacious...... Six meters? Eight meters? Forget it, just do it in one step and 12 meters! ”

Tang En simply set the width of the road at 12 meters, although it is too wide, but it is better to plan in advance than to demolish it later, and before the road is fully utilized, the two sides of the road can be used as the area for those shops to set up stalls, and it will not be wasted.

Tang En was afraid that after a long time, this main road would spontaneously turn into a bazaar......

"Let's plan the building of the residential housing in the form of a field-shaped community, and probably draw a picture of Fiona and she should understand, let her figure it out for herself......

With a stroke of his pen, Donn easily and casually set the main layout of Ellington's building in the future.

However, for a city, the isolation of the living area of the industrial area, the layout of the green belt, the layout of the living quarter, and even the width of the road are not the most important, the most important thing is that Don is only starting to have a headache now.

In modern cities, there are public toilets and fire stations at intervals, which are all part of the infrastructure that the city must equip with, and even strictly speaking, the planning of parks, but the scope of Ellington's current redevelopment is too small, so these problems can be ignored for the time being, but there is one problem that cannot be avoided at all, and must be determined in advance now.

That's the city's underground drainage system.

That's right, Donn came to Ellington until now, and he hadn't noticed that there was underground drainage, not even an above-ground drainage ditch......

Don didn't know if it was because there was less rain during the rainy season, or because of the high terrain and the low terrain of the Emerald River, so there was no need for drainage, but in any case, it was impossible for a city to be without a drainage system.

With no drainage system, Don couldn't imagine how dirty it would be when the population grew, and he didn't want his city to become that kind of smelly place.

However, Tang En only knows that the urban drainage system is to treat and remove urban sewage and rainwater, and in the case of the implementation of the sewage and rainwater diversion system, the sewage is collected by the drainage pipeline, sent to the sewage treatment, and discharged into the water body or recycled; Stormwater runoff is collected by drainage pipes and discharged into the nearest water body.

But he didn't know what to look out for in the design of the drainage system.

"Hmm...... What is the diameter of the drain pipe? Rugged? What is the load-bearing structure of the land? ”

Tang En thought about it for a long time and was still confused, and finally had to write down these points according to his previous impressions, no matter what, the drain pipe must be strong and durable, and the diameter must be large enough, otherwise no one can stand the blockage of the drain pipe every three or five times.

As for the separation of rainwater and sewage, it is easy to say that the two drainage systems are completely isolated, and the rainwater is discharged directly into the Emerald River through the above-ground drainage, while the underground drainage system is connected to each household and only discharges sewage.

As for the place where the sewage is discharged...... Directly connected to the large cesspool of the paper mill, it is regularly sent to the fire element world for destruction!

The sewage capacity is insufficient, and it is only necessary to increase the size of the sewage tank and the frequency of destruction of sewage.

"What a genius I'm in!"

Don looked at the drawings, exclaimed, and gave himself a big thumbs up!
