From Erdogan's Heavenly Realm to Aran on the Adriatic Sea, a ladder that runs through the entire earth has descended, and at the bottom of the ladder are buried countless dilapidated ruins, and at the top of the ladder lies the crown of the gods. Pen ~ fun ~ pavilion www.biquge.info

So, how did the ladder come about?

In the primeval period, when the sun fell, the ground was shrouded in darkness, cold, death, gray mist followed, and all races were threatened with extinction.

In desperation, eight humans dug up the ruins of an ancient god in the deepest part of the earth, where the truth of the universe was recorded, so they delved into the research and developed the "ladder" system, which emitted a mysterious light wave from four different directions on the earth.

The light waves intersect and produce light that covers the entire earth, thus playing the role of the original sun.

Those eight human beings were also hailed as the "Light of the Firmament" by later generations.

Humanity flourished again, and with the continuous study of the relics of the ancient gods, the first people to discover it continued to refine the "ladder" system, and made the most surprising discovery: by connecting the human brain to the "ladder" system, the inner potential of human beings can be greatly exerted, and some people can even obtain coveted superpowers, and these abilities are enough to change the whole world.

However, there are four ladders, each representing an epoch, and each ladder alternates its position, and the epochs alternate with each alternating position, but when it is all alternated, the previous epoch is often forgotten.

After a few epochs, it is impossible for a non-scholar to know a little bit about the primeval times, and even a scholar, they only know certain fragments.

But despite the rise and fall of nations, for centuries there has been a prophecy in countless ancient ruins around the world, that is, the apocalypse of the sky, which will not change a little over time.

The prophecy says that whoever reaches the top of the ladder will take the crown of the gods and become the king of the heavens, gaining the power left by the old gods to save all mankind - and at the same time, he will destroy the world once again.

Countless civilizations lurk beneath the ladder.

It was the place where the drifts of the ancient nations converged - Yaran.

The City of Light - Arlan is an artificial floating island, it is surrounded by the endless ocean, and further down is the ancient ruins, and in its center stands a pillar of light, because it reaches to the sky, so people also call it the ladder of the sky.

And what it brings to human beings is not only the light that replaces the sun, but also the ladder system that is closely related to its life.

At birth, a tiny chip is implanted in the first motor area of their cerebral cortex to synchronize the brain with the ladder system.

Everyone has the opportunity to awaken superpowers, but it doesn't mean that everyone can have superpowers.

To date, the ratio of superpowers to incapacitates on Earth is 1:1000.

Due to the social changes brought about by superpowers, the government has increased policy support for superpowers, and there are detailed arrangements for where to go from primary school to university and even after graduation.

Once he awakens his superpowers, it indicates that he will be able to rank above the middle class in the future, and he will also gain the corresponding status and identity.

The ladder system, which is closely linked to superpowers, is divided into ten levels, and only those who are skilled enough in their abilities can be upgraded, and the higher the level, the stronger the ladder system strengthens its abilities, and when it reaches the highest level, its abilities can be comparable to those of gods.

"Whoever enters the ability of Lv10 will be given the ancient and noble title - the light of the sky, and he will become the king of all, leading the rise of mankind, also known as the king of the firmament."

-- Speech on "The Earth Federation Congress's Plan No. 1 on the Classification of Capable Persons"

However, in this era, the highest number of human abilities is only Lv7.

Today's human beings are just a gravel in the vast universe, according to ancient documents, with the emergence of the ladder as the dividing line, the earth's human history is divided into two eras - the Common Era calendar and the Bright Era calendar, referred to as the light calendar.

From the moment the ladder appeared, it broke the barrier of time and space between the planets in the universe.

Ladders are not only exclusive to Earth, but also exist in other galaxies in the universe, and they have discovered that as long as the ladders are linked to each other, they can teleport to each other's planets.

Since then, the universe has ushered in the "Age of Discovery".

But it also brought about the outbreak of war in space, in order to compete for energy, those planets with a low level of civilization became colonies of powerful planets, and the earth was also invaded by other planets, but with the defense of its own ladder system, it was saved again and again.

But another threat looms.

The ladder system was built on the ruins of the Old Gods, but as it continued to be explored, an unknown life known as the Emissary of the End appeared.

They are huge, ugly, and powerful, and they always appear in hordes, attacking life on the planet where they live.

In the year 3017, those powerful planets were tired of war and the invasion of unknown life, and signed the "Interstellar Friendship and Peace Treaty" with each other, and the universe ushered in a period of peace.

In the year 3027, the earth was opened to the outside world because of its ancient and brilliant civilization, and many life beings from other worlds came to study and study.

In the year 3050, the school founded by the central city of Arlan on Earth allowed otherworldly beings to enroll. Increasingly, the Earth is becoming a hub for exchanges between other civilizations in the universe.

In the same year, the Interstellar Bank was established, and the exchange rate of currencies between planets was uniformly measured.

In the year 3,100, the population of the earth was only 300 million.
