Lin Xuan transmigrated into a world where demon beasts rampaged. He became one of the lowest ranking wasteland reclaimers in the Germinal Organization to explore the mystic realms.

The Zero Realm mystic realm was the Giant Rock Cave. The First Realm mystic realm was the Demon Ant Nest. The Second Realm mystic realm was the Tree King Sea.

Lin Xuan’s eyes were wide open. He was well-versed in how this worked. This was similar to the AFK games that he played in his previous world.

As such, he began his comfortable journey of becoming the strongest.

Up until one point, the Germinal Organization discovered that he was abnormal and decided to deal with him. It only then did Lin Xuan realize that even Seventh Realm fighters and the managers of the organization were inferior to him.

Over a million years ago, the first human contracted with the first Spirit. Ever since then, Spirit use has become commonplace. Humans used Spirits to carry items and start fires. Eventually, even start wars. Thousands upon thousands of years past and one day, one human did the impossible. He transcended his mortality and ascended to the realm above.
