The majestic and majestic Space School is held up by a huge levitating mountain above Kote, pulled by a powerful magnetic force. It stands in the towering clouds, faintly, revealing a mysterious and hazy outline, looking from afar, like a dragon exhaling into a towering city, bizarre, making people think about it.

It was founded by the earliest teacher and principal of the year. After the baptism of wind and rain over the years, it has been constantly reforming, changing, carrying forward and magnifying...... As a result, it has become a long-awaited gathering place for talents. Whether it's technology or political power...... The space school has always played the role of an engine, and the hegemony is quite large.

The school is a huge building shaped like a flying saucer, built diagonally, surrounded by mountains and rivers. Its whole body is made of refined black scale stone, which can concentrate light and astigmatism. At night, the wall releases the light energy absorbed during the day, setting off the whole school like a splendid palace, which is spectacular and dazzling.

On the top of the giant rockery in the center of the school, a huge building in the shape of an eagle is spreading its wings and soaring. It's more than just a decorative building. The structure and design inside can be described as ingenious-

In the eyes of the eagle-shaped building, the most sophisticated defenses and mechanisms in the space school are hidden. Once the enemy situation is detected, it will immediately sound the alarm and activate all the prevention and control systems throughout the territory of Kote, so that the enemy has nowhere to hide.

Above the school, there is a giant head with a helmet, which floats in a predetermined track, constantly circling around. Its image is based on the former principal of the school, which was specially built to commemorate the earliest founder and founder.

Not to mention how many unknown mysteries are hidden in this solemn statue. The hardness of the copper walls used in the periphery alone is estimated to be impossible to destroy nuclear warheads.

There must be a reason for such painstaking arrangements by the school. Because, there is a shocking secret hidden here - thousands of secret rooms full of many mechanisms and confusing layouts, among which there is a hidden place where black energy is "sealed".

Black energy - is a special kind of energy, the size of which depends on environmental factors, and is a very dense black crystal. In the Western Demon Realm, it has always enjoyed the reputation of "King of Gems". Because its formation must have earth, water, wind, fire, and thunder at the same time...... and other innate factors, and all of them are indispensable. So, in the whole universe, it is very rare.

Black energy is small in size, but it is amazingly powerful, and it is the "king of killers" that can hardly be compared with any homogeneous substance. If the people in the Demon Realm get it and use it properly, they can not only repair and multiply their infinite power, but they can even burst out with earth-destroying energy, bringing subversive disasters to the world.

The black energy "sealed" by the Space School on its own, the size of an adult's fist, is a rare "King of Gems", and its origin is an accident (follow-up answer).

Because of the limited amount of black energy, the executives of the space school studied it day and night behind closed doors, and did not come up with a single reason. In order to suppress its powerful radiation source, the Space School worked hard to develop a black box and "sealed" it inside. The external force is suppressed, and he does not dare to act rashly. In addition, according to limited information, once the black energy is combined with a mysterious substance, it can emit a very dazzling blue light, called "blue wings". When the light of the "Blue Wing" is activated, a terrifying force erupts, and the world will be as dark as the end of the world, and the ensuing catastrophe may bring unimaginable destruction to Kote.

Therefore, black energy has always been a "taboo" for the Korters, and they dare not make mistakes easily.
