It was not yet three o'clock in the afternoon, and Zong Shen had a lot of time to slowly check the treasure chest items. Thinking of this, he turned over and took out a high-quality blueprint.

He unfolded the drawing and looked at its properties and architectural functions.

[Reservoir construction drawings (green)]

[Quality: Excellent (Green) Human Architecture]

[Requirements: Stone x200, wood x50, primary water rune x1, primary element crystal x3]

[Area: 50 meters long x 50 meters wide x 1 meter deep]

[Sturdiness value: 1200]

[Building Armor: 20]

[Building magic resistance: 15]

[Able to store a certain amount of water and build a water circulation node in the territory]

[The built-in primary water rune can purify water quality to a certain extent, and a water rune needs to be replaced every 720 hours]

[This architectural drawing has no preconditions and can be reused for construction]

[Construction time: 2 hours and 22 minutes]

(Very good, the supporting water diversion buildings are now complete)

Zong Shen clapped his hands and thoroughly learned and mastered this drawing.

Speaking of the reservoir, the building may sound a bit unremarkable at first, but in fact, water is an essential resource for the daily development of the territory.

Water resources are also a resource, and they are also strategic resources.

Farmers and soldiers need drinking water every day.

There are also the wargs under the crotch of the more than a thousand wolf cavalry. The knights' horses drink much more water every day than humans. This does not include the manticores, griffins and newly conquered ones in the territory.

Bloodtusk wild boar herds all need a regular supply of drinking water.

In addition to daily life, manufacturing and workshops also require water.

The ways to obtain water are divided into natural ways and magical ways, plus some water-based rare objects and props.

Among them, natural channels are the main way to obtain water resources.

And this [Reservoir Construction Drawing (Blue)] just meets the needs of the territory.

Build some more canals to connect the streams and canals in the northwest of the territory, and eventually merge into the reservoir.

This creates a water supply node within the territory.

Both reservoirs and canals can be constructed repeatedly, and the reservoirs also have a certain water purification effect.

"Practical level√, it would be better if we could get higher-level reservoir construction drawings."

"Now this is enough to make do."

Zong Shen evaluated it, and then took out the next blueprint, which was also a new type of sophisticated grade blueprint.

However, this thing does not belong to architecture, it should be regarded as a semi-finished product of construction.

[Floor reinforcement stone slab 2 manufacturing drawing (green)]

[Quality: Excellent grade]

[Requirements: Stone x30, Iron x3]

[Size: 10 meters long x 3 meters wide x 20 centimeters thick]

[Sturdiness value: 500]

[Building Armor: 10]

[Building magic resistance: 5]

[Reinforced stone slabs can be laid on stone pavements to reinforce them]

[Multiple reinforced stone slabs can be stacked]

[Maximum number of stacks: 3]

[Production time: 15 minutes]

(The first choice material for hardened ground, suitable for hardened road paving in the territory, up to three reinforced stone slabs can be stacked to obtain additional solidity value and double resistance)

"Practical level √, let's learn it later."

Zong Shen poured himself a glass of wine and drank while checking the properties of the drawing.

After reading the detailed attribute information, he learned and mastered the drawing with a flick of his backhand.

The next sophisticated level drawing is a pig pen, similar to the [Small Ranch Construction Drawing] he had obtained.

It also has practical value and can be used to quickly build a pigsty.

When the Bloodtusk wild boars breed on a large scale, they will be used to corral those white-boarded wild boars.

At that time, we may have to introduce some domestic pigs to raise them and conduct cross-breeding.

As for the attributes, he didn't bother to look at them. After he learned them, he added them to the [Build] list. In the future, it was up to Mariel to decide whether to build or not and how much to build.

Next came the excellent-level drawings, and some of them interested him.

The first is a blue excellent-level manufacturing drawing, and the corresponding manufacturing item turns out to be a street lamp!

Although there are magic lighting equipment in the lord's fortress and various high-level buildings.

But in other parts of the territory, including the living areas, daily nighttime lighting is still primitive.

Indoors, only grease candles are used, while outdoors, simple and crude bonfires are made of wood.

Grease candles are not expensive, but they cannot hold up to the large number of stone houses and folk houses in the territory. You can only prepare one for each house, so everyone has to save some.

Now that the manufacturing drawings of street lamps have appeared, maybe we can get a safe and reliable light source.

Anyway, no one rules that street lamps cannot be placed in stone houses.

I don’t know if this thing has its own light source or if it needs to consume magic energy.

With doubts and expectations in his heart, he took out the drawing from the storage compartment and looked at it.

[White Stone Street Lamp Manufacturing Diagram (Blue)]

[Quality: Excellent]

[Requirements: Primary white stone (energy-draining magic crystal) x2, iron x25, primary magic crystal x1, copper x5, wood x15, hemp rope x3, mithril x1]

[Manufacturing time: 1 hour and 42 minutes]

[Each primary magic crystal can light up the white stone for about 720 hours]

[Controllable lighting and extinguishing can be achieved by manually disassembling the magic crystal]

[Simple and easy-to-use white stone street lamps can provide better lighting than candles]

(White stone street lamps bring the light of freedom to the residents at night)

"It turns out that the magic crystal that has exhausted its energy is called white stone!"

Zong Shen finally gained some knowledge and learned a little knowledge.

The main material of this street lamp is white stone, and additional [Magic Crystal] is needed to supply energy.

As for other materials, it's not surprising, there are quite a few reserves in the territory.

We also have a lot of [Elementary Mana Crystals] in reserve, so there is no problem in assembling some street lights.

After all, each [Elementary Magic Crystal] can light up the [White Stone Street Lamp] for 720 hours.

Calculated based on an average of 8 hours of lighting every night, it can be used for a full 90 days!

Zong Shen is quite satisfied with this service life.

The only weird manufacturing material was [white stone], and he wasn't sure whether it was available in the territory.

You still have to ask Mariel. Normally, the magic machinery in the territory should be replaced with [Magic Crystal] after use.

She is responsible for everything.

I don’t know if the [Shiraishi] I replaced is missing.

If it really doesn't work, you can get some from the earliest one [Goblin Airship (Purple)].

There should be [White Stone] in the energy cabin of that airship.

Thinking of this, he used the [Communication Crystal] to send a communication request to Mariel.

Explained the matter of [Shiraishi].

The communication was quickly disconnected, and Zong Shen learned the drawings.

He doesn't know the lighting effect of [White Stone Street Lamp (Blue)] yet.

But according to the notes in the strategy module, it should be much stronger than ordinary candles.
