For the leader of the Yongye Army, although the perception tower that Sean wanted was a bit unique, it was really not a big project.

Both construction personnel and construction materials are readily available.

The construction work on the northern fortress also never stopped for a day.

After repeated surveys of the geographical environment around the energy reaction room, Ferdinand overturned Sean's first draft of the idea of ​​placing the perception tower directly next to the energy reaction room.

The surrounding area of ​​the Northern Fortress is also a standard karst landform with clusters of lava caves. The Yongye Army Leader has discovered no less than eight huge natural caves in the surrounding area and successfully opened and widened them to become part of the Northern Fortress.

In other words, the actual area of ​​the Northern Fortress is much larger than imagined.

The Law Order Tower to which the energy reaction chamber belongs and the research institute to which it belongs are both built underground.

You can imagine how huge the underground space here is.

It is obviously not a suitable choice to build tall towers on them, especially those that are likely to be continuously expanded in the future.

After discussing with Sean, Ferdinand placed the perception tower in the northern part of the northern fortress.

The Grand Canyon of Odin is a bit too narrow for a city. In order to develop, they not only developed all the caves, but also leveled out a large area on the top of the mountains on both sides.

If you look at the vertical plane, the northern fortress is in the shape of a huge "ˉ\\__/ˉ", and the small hands on both sides continue to extend to both sides of the mountains as they expand.

The mountain in Beishang City is extremely stable and close to the energy reaction room, so it is undoubtedly the best choice.

Sean greatly appreciated this proposal.

In this way, the perception tower has the mountain bonus, which can not only encompass the entire northern fortress, but can even extend outwards.

The biggest difference between Sean and Ferdinand on the perception tower should be in the selection of the main body.

According to Sean's original idea, it would be enough to use a reinforced concrete structure as the skeleton and conventional boulders as the walls.

Ferdinand raised objections. He believed that it was more appropriate to use raw jade as the main construction material.

The reason he gave is very good. Gemstones are the best carrier of magic energy currently known. The more magic energy that can be stored in the perception tower, the better. It may be able to complement the energy reaction chamber.

.

The leader of the Yongye Army does not have the ability to build a perception tower entirely out of gems, but jade is produced in the mountains of Andis, and several large jade mines have been discovered, so it is still no problem to use raw jade ore.

Even Sean's eyes widened in shock when he heard Ferdinand's proposal for the first time. He swallowed several times and said, "Isn't this too luxurious?"

It is true that the Yongye Army leader now owns several large-scale jade mines, but good jade is not a carrot and cabbage, and it is not easy to come out. Many times, after half a day of cutting, not even a piece of jade residue can be seen.

The project of the Sensory Tower is neither big nor small.

Now the drawings have been changed beyond recognition by Ferdinand. In addition to the main tower's shape remaining unchanged, several additional structures have been added. To sum up, the number of stones required is not a small amount.

Not to mention that it requires time-consuming and laborious transportation from the place of origin.

"The Mage Tower has always been a very expensive building. According to my research in recent years, all the Mage Towers in the Ancient Andis Empire are made of very particular materials. I suspect that they were once inlaid with various gems.

This is also the reason why they were severely destroyed. However, during the ancient Andis Empire, there was no cement, so the texture of the stone had to be considered. We did not consider this aspect. The frame was cast with steel and cement, and the original jade stone was slightly polished.

Just fill in the inlay and go up."

As Ferdinand spoke, he waved his arms and said domineeringly: "We either don't do it, or we do the best. This is not just a matter of a perception tower, but also a matter of the future mage tower."

Sean couldn't help but feel moved, except that he felt that what Ferdinand said made sense.

It is also because the Perception Tower will be closely related to your future cultivation, and it will even be involved in the lifelong event of whether you can become a master warlock.

Once his experiment is successful, it means that the leader of the Eternal Night Army will control the method of cultivating and controlling warlocks.

At that time, it will be subversive news for the entire power structure of Ashan continent.

This cannot be measured in terms of money.

And there will only be more and more buildings like the Perception Tower that are related to magic in the Eternal Night Army.

It will be beneficial and harmless to find out early.

However, Sean is not someone who is easily shaken. He pondered for a moment and gave a more prudent suggestion: "How about this? Before we officially start construction, we build a few models first and combine all the materials one by one.

Give it a try and see which one works better, and then make a decision before it’s too late.”

"Lord, this is a prudent opinion, and it is natural, but I still firmly believe that the raw jade stone is the most suitable." Ferdinand said confidently.

This made Sean very puzzled, where did Ferdinand's confidence come from?

For such a wide-ranging matter, Sean believed in the final test results.

Regardless of whether Sean uses his privileges or not, his affairs as the supreme ruler will always be ranked among the highest priorities of the entire military leader, even if it is the building materials he needs, the same is true.

Within a week, all the building materials he needed were arriving one after another.

Since he has to do this, Sean will not simply compare raw jade stones, but will collect all the building materials that can be found in the territory.

However, many unconventional building materials are used to accompany the run. The main force of this experiment is mainly the masonry fired by the Yong Ye Army leader himself, ordinary rocks, jade rough stones, marble, pure steel, etc.

Even Obsidian got a copy.

The experimental results shocked Sean for a while. The one with the best effect turned out to be raw jade.

The small perception tower built with raw jade stones, after being connected to the magic energy channel, the entire perception tower turned into a huge charged gem.

Yes, many raw jade stones do not even contain jade slag, but their overall structures are similar and they still have a weak function of storing magic energy.

This weak refers to the situation when it is the same volume as jade, but it cannot hold up. The size of the original jade stone is large enough, the quantity used in building the perception tower is enough, and the stored magic energy is naturally enough.

After it is fully charged with energy, the entire small perception tower shines with a jade-like soft light, and the visual effect is absolutely one-of-a-kind.

In this case, even if the energy supply to the energy reaction chamber is cut off, it can persist for a period of time.

This is not the most important thing.

The most important thing is that it is a huge charged gem, which means that Sean can inject the magic energy with his own spiritual brand into it bit by bit.

It is also magic energy. Those that have their own spiritual imprint and those that do not have two completely different properties.

For example, if Sean diverts the magic energy from the energy reaction room and wants to use it for his own use and perform magic, he must first imprint his own spiritual imprint on it, otherwise they will not listen to you at all.

The spirit of warlocks is also limited. If they use it too much, they will become mentally exhausted and even fall into a self-protection coma.

But if you have your own spiritual imprint, you can extract it as you like without any consumption or burden on yourself.

This is equivalent to having an extra mana library out of thin air, and the spells stored in it consume unprecedented energy. The warlock who sits on it will be nearly invincible.

Based on this alone, Sean decided to use raw jade stones to build a perception tower.

At the same time, Marshall was also ordered to make every effort to explore and develop matters related to the jade mine in the territory, because its usage will increase dramatically in the future.

Because this perception tower will be just the beginning, and the number of subsequent constructions will not be less than three. At least the three control-level warlocks leading the Eternal Night Army are worthy of owning one.

Their own energy storage characteristics mean that they can still function without the energy reaction chamber, but it is just a matter of how long they last.

The results of this experiment also show that all solid stones have certain characteristics of storing magic energy, it is just a matter of strength.

When the first batch of raw jade stones was transported to the Northern Fortress, the ground was officially broken for the Perception Tower.

Instead, Sean left the Northern Fortress, took two young griffons, and embarked on a journey to the royal capital of Valesta. He needed to arrive before the New Year.

Regarding the perception tower, he had almost discussed it with Ferdinand, and the rest was the specific construction.

In this regard, Ferdinand is the professional. Professional matters are handled by professionals. This is the principle that Sean believes in. Mixing in on his own will only make things worse. Ferdinand is not the kind to listen to him.

People who mess around.

This time Sean did not fly directly on the black collar, but instead took water transport.

After all, in addition to the two young griffons, there are also specially trained breeders accompanying them.

The accidental release of the perception tower delayed Sean's stay in the Northern Fortress for two more weeks, making this trip rather troublesome.

A heavy snowfall caused the Andis inland lake to enter the freezing period. Although the ice was not thick, it still trapped the boat waiting for Sean here.

Sean had to travel 200 kilometers on mountain roads to get to the Twin Cities and take the Twins to Valesta.

The water transportation along the Jakob River and the Danube River is not unobstructed all year round. The upper reaches of both rivers, especially the section in the Andis Ring Mountains, have a freezing period of nearly two months.

Viewed from the air, the Andes Mountains look like an oval egg, but this egg is not placed due east or west, but with its head to the north and its tail to the south.

The Jakob River flows southeast in the Andes Mountains, while the Donau River flows southwest.

Affected by the terrain, the air flows slowly in the Andis Mountains, which makes it prone to hot summers and cold winters. In addition, the latitude is not low, and the Kentana Icefield is a bad neighbor. Cold winds blow here every year, making it cooler than outside the mountains.

It's normal to be 20 to 30 degrees colder.

This situation has somewhat eased with the reflow of the Jacobs River. When the Andis Inland Lake was still an above-ground lake, the humidity here was relatively high, and it was truly wet and cold.

However, it was precisely because of this situation that the leader of the Yongye Army was able to use the ice wall tactic when fighting against the invasion of the Kentana barbarians in the mountainous area, and deceived them.

If it were changed now, the same tactics would be effective or not.

Although inland lakes still freeze, they are usually not too thick and will melt when the weather gets warmer. The Jacobs River is also less likely to freeze because it has become living water.

This has some impact on the flourishing commercial trade of the Yongye Army Leader, but it is not fatal.

Because most of their products are monopoly products and are in short supply, they cannot be shipped out temporarily, which does not prevent them from working overtime. As long as water transportation resumes in the coming spring, the products will be out of stock in only a month or two.

Moreover, the Yongye Army Leader did not put all his eggs in one basket.

They are now building multiple industrial zones.
