Asuka City.
At this moment, Su Lan was standing near the Flying Bird City Naval Battle City.
Looking at the massive battle defense line that was being rapidly erected before me, I felt a great sense of anticipation.
The naval battle city that Su Lan built in Flying Bird City, when viewed from above, has a crescent-shaped outline.
This is the best form of defense.
The purpose of Naval Battle City is to defend against and hunt sea monsters, as well as to provide a training ground for mages.
Therefore, the defensive capabilities of the naval city must be strong enough; it is not enough to merely withstand the attacks of commander-level sea monsters.
It must be able to withstand the attack of a monarch-level siren.
Otherwise, if a monarch-level sea monster arrives, the defensive dikes of the sea battle city will collapse directly, which would be a complete waste of effort.
Therefore, the Asuka City Naval Battle Castle will build three double-layered steel dikes using a combination of seawall stones and super-strong steel as its defense lines.
Seawall Stone is a type of mineral that can be used to automatically construct seawalls through magical plasticity and melting.
Its characteristics include strong initial plasticity, which can quickly and perfectly repair any damaged parts of the defensive fortifications without requiring a solidification period.
Furthermore, seawall stone possesses a hardness characteristic; after the first melting and chaining process, it loses the possibility of further shaping and its properties become extremely hard.
With such a large accumulation, even a monarch-level demon would not be able to break through in a short time.
The seawall stones, combined with a high-strength steel structure, can be fitted together to enhance the seawall's defensive capabilities.
Of course, seawall stones and super-strong steel with such high defensive capabilities are very expensive.
Especially seawall stones, which are found only deep in the seabed.
The seawall stones needed for the construction of the Asuka City Naval Battle City were specially dug up from the depths of the sea by Serafina.
When Wei Fang learned that the Alien Hunters possessed such a large quantity of seawall stones, he was practically drooling with envy.
Because seawall stones are not only incredibly effective for building dikes and fortifications, but they are also the best defensive material for land-based fortifications.
Of course, in addition to seawall stone and super-strong steel, the third layer of defense will also incorporate special magical ores to enhance its hardness.
Currently, the three defensive fortifications of Asuka City's Naval Battle Castle were built simultaneously.
The three defensive fortifications consist of the first dike, the second dike, and the third dike.
The first dike is the outermost dike, and its height is relatively low, only 50 meters above sea level.
This is the initial height to resist the raging waves and small sea monsters, serving as an early warning, buffer, and deterrence of the sea monsters' offensive.
The second dike is the secondary main dike of the naval city.
The main breakwater is 150 meters above sea level and can withstand attacks from sea monsters that are hundreds of meters tall.
In other words, the attacks of sub-monarchs, minor monarchs, and orthodox monarch-level sirens can be mitigated by the second dike.
As for the overlord-level and supreme monarch-level sea monsters, the third dike will serve as the final line of defense.
The third dike, 300 meters above sea level, was constructed with materials that were more robust and durable than those of the first and second dikes.
According to Su Lan and Serafina's calculations, the third dam, in conjunction with the formation, could withstand the full force of the Sub-Emperor's attack without collapsing.
Then facing sea monsters of the Great Monarch or Supreme Monarch level would be even less of a problem.
Of course, even if a monarch-level demon attacks the Sea Battle City, the [Alien] Hunting Grounds will not stand idly by and watch the monarch-level demon destroy the fortifications.
The alien girls of the [Alien] Hunting Grounds will capture or kill monarch-level demons in the coastal waters in advance when they appear.
As for whether there are concerns about the alien girl fighting in the sea, and whether it will affect its combat effectiveness.
There's no need to worry.
The alien girl, transformed from a siren, is naturally aquatic and excels in sea battles, even more so than the siren herself.
There are now four major naval battle cities in the world, and each of them has two defensive dikes.
The reason why Asuka City Naval Battle City has three defensive dikes is because Asuka City Naval Battle City covers an area larger than the four major naval battle cities.
Take Tokyo Naval Battle Castle as an example.
The Tokyo Naval Battle City is estimated to cover an area of over 50 square kilometers, including all city blocks, seawalls, defensive zones, ports, training grounds, and buffer zones.
The first phase of Asuka City Naval Battle City covers an area of approximately 200 square kilometers.
That's right, it's still the first phase of Naval Battle City.
Once the number of alien girls in the [Alien] Hunting Grounds exceeds 100,000, the second phase of naval battle city construction will begin.
Asuka City's naval battle castle is four times the size of Tokyo's naval battle castle, which lengthens the battle line, making two defensive dikes unsuitable.
If it weren't for the exorbitant cost of the fourth defensive dike, Su Lan would have considered building it.
But thinking about it later, it wasn't necessary.
According to the plan, Asuka City's Naval Battle City will be divided into 128 blocks, each with its own functional areas.
Forward combat zone, central living area, and rear supply area.
As for how it will be managed, the Magic Association and the Guardian personnel will be brought in to manage it together.
The areas belonging to the [Alien] Hunting Grounds are managed independently by the alien girls, and because they are not open to the public, there are basically no outsiders.
The areas allocated to the Guardians and the Magic Association will be primarily managed by these two parties.
Of course, the [Alien] Hunting Grounds will also be supervising from the sidelines.
Alien Hunters operates under a unique system and does not accept any external intervention.
In other regions, the operational model has already begun to be drafted, spearheaded by Shao Zheng and Hua Zhanhong, among others. Whether it's task distribution, combat rotation, logistical support, or even more covert fronts, plans are being developed.
As for the major families and powerful forces, their participation and profits in the first phase of the naval battle city were not significant.
Their main expectations are placed on the second phase of the naval battle city.
Therefore, each large family began to raise huge sums of money and mineral resources.
They knew that the family might suffer losses in the short term.
But if you occupy just one or two blocks, the resources will be returned many times over within two years.
The ocean is teeming with countless sea monsters.
For them, every siren is an inexhaustible resource.
That was like money just pouring in.
Moreover, by then, the [Alien] Hunters will not occupy more than half of the naval battle districts; they will be able to occupy a larger share.
Because starting from the second phase, the defenses of the naval city have spread to other coastal cities.
However, the portion of the fee waived by the [Alien] Hunter will be used to obtain a place in the third and fourth phases.
At that time, all the coastal cities of the Great Xia will be transformed into naval battle cities, and each naval battle city will have an alien hunter stationed there.
Sacrificing a small portion of the quota in exchange for widespread success across the entire sea area makes this trade-off worthwhile.
Standing beside Su Lan at this moment were not only himself and Serafina.
Today is Saturday. Mu Nujiao, Ai Tutu, Bai Tingting, Ding Yumin, and Ye Xinxia, who don't have to go to school, all followed Su Lan to Flying Bird City.
Previously, they had only heard that Su Lan had bought Asuka City.
I didn't realize it when I was in Shanghai.
Now that they've come into close contact with Asuka City, they've discovered just how incredible the man before them has accomplished.
