12 Miles Below - Chapter 3: You Should Have Left it Closed, Dumbass

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.
