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.

In the cave, Lin Xuan faced a huge demon ape with a puzzled expression.

"Someone seemed to have called me just now?"

"Forget it. Fighting the experienced mystic realm king is more important."

Lin Xuan used his Observer skill and discovered that although this Demon Ape King had high physical resistance, its fire resistance was very low.

He immediately took out the Blazing Fire Codex and began to throw fireballs randomly.

Ordinary martial artists' Fireball were all ordinary white. Very few people would be bothered to pay attention to the advancement of the Fireball.

However, Lin Xuan's Fireball was of the peerless golden grade. Moreover, it was the same level as his cultivation. Now, it was also at level nine of the Fifth Realm.

In addition, he had many equipment and runes that could increase fire magic and reduce the consumption of magic power.
