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.
