Three years have passed in a flash.

It has been three years since the great war that affected the entire pattern of the Yashan Peninsula.

The entire Yashan Peninsula is also developing in the direction of a huge military fortress as planned by Su Huan.

At this time, if you look down at the middle and high altitudes.

You can see that there are a large number of fortresses and fortresses scattered throughout the Yashan Peninsula.

In the past three years, the construction of various fortresses and fortresses has never stopped.

Even now, some scattered fortresses and fortresses are still being built.

These fortresses are fundamentally different from the military fortresses and fortresses of the major fortress cities on the Asan Peninsula.

First of all, there is the change in the materials used to build fortresses and fortresses.

The materials used to build fortresses and fortresses are nothing more than reinforced concrete, plus a large amount of special steel, and poured into thick walls that are difficult to break through for dangerous and terrifying species.

Defend against dangerous and terrifying species, mainly relying on thickness, to defend against dangerous creatures.

However, these new forts and fortresses did not rely on the high walls of reinforced concrete structures.

These high walls may be able to defend against danger and terror.

But under the energy attack of the Nightmare Species, it was already difficult to resist.

Not to mention the nest plague army that is now attacking human cities, even if it is a small force, there are high-ranking races.

The high walls of the reinforced concrete structure are built with special steel as the skeleton, but it is difficult to withstand the blows of nightmares.

If you still follow the old path, build fortresses and fortresses that even the Nightmare Species can destroy.

The Asan Peninsula will not cost so much manpower and material resources.

In the past few years, all the fortresses and fortresses have been built.

All with a completely new pouring process and a new material.

Energy-absorbing materials.

This is a special material that, according to the course of history, should appear thousands of years later.

As the name suggests, energy-absorbing materials that are able to absorb energy.

When a dangerous creature's energy attack hits it, the energy is absorbed by the energy-absorbing material.

And that's not all, the energy-absorbing materials that absorb the energy will become extremely tough.

This absorbed energy can change the structural stability of the energy-absorbing material, so that the more energy it absorbs, the more indestructible it becomes.

This kind of technology, if it can be used on armor, can definitely add an excellent layer of protection to human masters and pets.

Unfortunately, even after thousands of years, energy-absorbing materials can only be used in ready-built buildings.

For no other reason, the material is too heavy and cumbersome.

The weight of energy-absorbing materials is extremely heavy, and the energy intensity and density that can be absorbed per unit volume of energy-absorbing materials are limited.

Only by aggregating a large number of energy-absorbing materials together can it exert its due effect.

If it is an energy-absorbing material of the size and volume of armor, not only is it far heavier than armor, but at most, it can absorb and resist the energy attack of the horror level.

When the energy attack strength exceeds the scope of the horror species.

Energy-absorbing materials of this size can cause structural damage due to the pressure they are subjected to beyond the limit.

But if it is to aggregate energy-absorbing materials together.

Aggregate an energy-absorbing material the size of an armor into an aggregate the size of an off-road vehicle or even a house.

will be able to absorb the nightmare-level energy attack.

And after absorbing the energy attack, his own toughness has become so strong that even the melee attacks of the Nightmare Species cannot be torn apart.

Moreover, the stronger the enemy's attack on the polymeric energy-absorbing material, the more tenacious it will be.

Not only that, but when the energy-absorbing material absorbs enough energy, it also generates a special absorption field.

Any fluctuations that propagate into the absorption field will be absorbed and eliminated in the form of energy.

This also prevents the enemy from directly destroying the lifeform that is in the defense of energy-absorbing materials with mental control or soul destroying skills.

Being in the middle of a suction field.

It can be seen as completely insulated from the energy attacks of the outside world.

When the energy-absorbing material is aggregated to the size of a city wall.

Don't talk about nightmares.

Even the energy attacks of the upper races, calamities, and calamities are difficult to break.

When the strong walls made of energy-absorbing materials are poured into the size of a military fortress.

Not to mention the calamity, even the natural calamity can only be dumbfounded in the attack.

And the energy-absorbing material that is as large as a military fortress.

It can even resist the frontal attack of the forbidden species.

This is the reason why in later generations, human fortresses and fortresses were able to withstand the offensive of the forbidden army.

Nowadays, military fortresses, fortresses are being built throughout the Asan Peninsula.

This energy-absorbing building material is widely used in construction.

Even, many years ago.

The top materials research institute in the new Black Light Fort hanging high above the Star Han Dragon Whale Island secretly began to study the process of this energy-absorbing material in accordance with Su Huan's instructions.

Not only that, but the secret production lines have already begun to be put into production in small batches.

The cost of this energy-absorbing material is undoubtedly high.

The price is far from being comparable to the cheap materials of reinforced concrete.

It's fine if it's a small batch of production.

However, it is used for the construction of a large number of military fortresses and fortresses.

Mass production.

It is a great burden for the finances of the entire Asan Peninsula.

This is also the beginning, the top level of the Supreme Ruling Council of the Yashan Peninsula has a lot of complaints about Su Huan's move.

However, Su Huan tried his best to disagree.

The manpower and material resources of the entire Yashan Peninsula were mobilized, and the manufacturing and production of energy-absorbing materials began, as well as the construction of fortresses and fortresses.

It's a pity, even if three years have passed.

The construction of fortresses and fortresses planned by Su Huan was not completed in the real sense.

In the final analysis, it is the production of energy-absorbing materials.

A large number of fortresses and fortresses cannot be built with energy-absorbing building materials.

Only partially energy-absorbing materials can be used.

But there's no way around it.

Even thousands of years later, at the end of human civilization.

The production of energy-absorbing materials is still a problem that plagues the human hierarchy.

The technology that Su Huan has come up with now can be regarded as a plan for the efficient production of energy-absorbing materials after thousands of years of improvement by the top researchers of mankind.

However, with the manpower and material resources of the Yashan Peninsula, it is still difficult to support the simultaneous construction of fortresses and fortresses built with a large number of energy-absorbing materials.

However, the current progress of the construction of the fortress and fortress is enough to satisfy Su Huan.

Those fortresses, due to the shortage and shortage of energy-absorbing building materials, may not be able to withstand the attacks of the forbidden species.

It is easy to resist natural disasters.

As for the military fortress, it may be difficult to resist the natural calamity, but the calamity species will never be able to break through the high walls of any military fortress.
