When Adam finished his turn and then was preparing to go home after several hours of work, his team received a fire alert. He didn't expect that he would die following his father's footsteps, but fate had something else in store for him.

Adam died, but he was reincarnated in another world as Aion Kresnik, with his memories intact. Still, an easy life wasn't waiting for him despite the fact that he had a system and the ability to change jobs and make a spiritual weapon change to many forms. The reason for that was the fact that he was the son of a war hero and, at the same time, the son of a war prisoner and one of the last members of a powerful bloodline of mages. A bloodline that was hated by the whole world.

Aion's goals in that world were simple, get rid of the discrimination surrounding his mother and then find out why he was reborn with such a system since he knew that things couldn't be that convenient...

By the year 3029 CE, Earth’s technology has developed rapidly, borders no longer exist, and Earth has been unified, marking the beginning of the era of the Federation.

At that time, a huge sword flew from the heavens, piercing the sun and causing a huge sensation on Earth.

Perhaps because the scabbard of the sword was already in tatters, countless shards have broken off from it following the collision with the sun and spread across the universe. Many of these shards have landed on various places across Earth.

With the arrival of the bronze sword and its shards, a new unlimited energy source has suddenly appeared on Earth. This energy source has since been named Spirit Qi.

Spirit Qi is like air, thick in some places and thin in others. As the Federation and other factions gather more shards, they discover more information on cultivation, pill refinement, Spirit Stone refinement, and other techniques. The words on the shards have an ancient feel to them, making it a trend for people to use ancient language.

The appearance of Spirit Qi rapidly makes the original energy sources obsolete and has completely changed people’s lives. Not only has the Spirit Internet been formed, Spirit Qi has also changed the course of Human Civilization, causing the world to enter a civilization of cultivation. This would later come to be known as the Spirit Inception Era.
