[Post-Disaster Era 07: The situation is becoming more and more turbulent. The three major forces of mankind are clinging to their respective territories, but in other places, alien beasts are rampant. Hunters and scavengers are equally terrifying. They are like foragers in the wasteland, using their greed to

Their eyes were fixed on every member of the same race or alien beast. The black rain caused the population to be reduced by 20%, and they caused the population to be reduced by more than 50%. The number of people who died at the hands of hunters and scavengers was higher than the number of people who died at the mouth of alien beasts.

The number of people is more than ten times greater.]

[Post-Disaster Era 27: A new generation of humans has grown up one after another. Without exception, they all have the characteristics of semi-metalization. Some have metalized bones, and some have active metallization on the skin, which allows them to feel touch, pain, and...

Skin with a hardness close to metal.】

[Post-Disaster Era 147: The long period of suffering has made people reflect deeply. This land where strange beasts are rampant and hunters and scavengers are everywhere is no longer suitable for settlement. People are just like wheat, and they will be killed by hunters and scavengers.

Regular 'harvesting', or being slaughtered by passing alien beasts, made it impossible for people to nomadic, the environment was too dangerous, they needed a mobile home, and the fortress was born.】

[Post-Disaster Era 153: The first true mobile fortress was born at "Lukeburg", one of the three major human gathering places. This mobile fortress was not created, but cultivated. It

It is a creature, a huge half-mechanical/half-biological structure creature. When needed, this big guy with a metal armor layer can move through dozens of thick mechanical tentacles protruding from below. It is a fortress and a shelter.

, is a movable home, provided that the energy it needs is supplied. This big guy will eat a lot of active ores to ensure the kinetic energy consumed when moving. 】

[Post-Disaster Era 268: Many mobile fortresses have been developed, and the corresponding facilities have become more and more complete. People live in the open space inside the fortress, and in the houses built, life safety is guaranteed. A new problem arises. Black Rain originally

When descending, not everyone was "mechanically contaminated", and some remained normal.】

[Post-Disaster Era 269: The conflict between normal humans and semi-metallic humans is increasingly intensifying. The cause is mutual discrimination. Normal humans think semi-metallic humans are weird species, while semi-metallic humans think normal humans are defective humans who have not evolved.

Product, the two sides started a war, and the war started while the pain caused by "mechanical pollution" has not yet passed.】

[Actually, this is the best choice. There must always be a place to tilt the sense of hatred. Whether they are normal humans or semi-metallic humans, they have experienced too much pain and torture. They are all tinderboxes that can be ignited. 】

[Post-Disaster Era 269: Normal humans call themselves the human race, while semi-metallic humans call themselves the mechanical race. They claim to be a semi-mechanical race that was favored by God and evolved from it. In the myth before the disaster, it was a race that came from outside the world.

Also called the Familia, it can be seen that the semi-metallic humans, that is, the Familia, have found the path they want to take.】

[Post-Disaster Era 495: This is a protracted war. The human race and the dependent race are completely separated. Generations of hatred have turned them into two intelligent races. They have changed from blood relatives to cousins, and then developed into distant relatives.

Today, they are hostile neighbors with each other. Their culture, food, beliefs, etc. have become completely different. Even the general appearance of their mobile fortress has to be different from each other.]

[Post-Disaster Era 529: The war between the human race and the dependent tribe subsided. The human race officially retreated from the protagonist of the historical stage to the second line. The three "invincible fortresses" were all controlled by the dependent tribe. 】

The human race in this world: takes shape with the power of the soul, and then fills and improves it with "bioactive metals" to create fighting methods such as avatars or biological armor.

Familia: Part of the body is "actively metalized", possessing super physical fitness, as well as extraordinary metal-based abilities brought about by mental changes.

Alien beasts: Possess powerful combat power, and many of them are overlord-level creatures.

Other races: They are all cultivated through acquired hybridization. These races are all cultivated by the dependents and used as coolies. They are called inferior creatures by the dependents.

Mobile Fortress: Super giant life forms with habitable space inside. They have simple intelligence. After meeting specified conditions, the Mobile Fortress can evolve and grow.

【World, begins.】
