Divine City, Guo Residence.

Guo Taiping sat in the room with a sword resting on his knee. After two days of meditating, his volatile emotions finally calmed down.

He opened his eyes, a dim purple light flashed in them. Compared to two days ago, his aura had changed significantly. He had astonishingly broken through to the First Rank realm.

"Well done."

Guo Taiping's expression was somber. Given the choice, he would never want that man to be his Mind Demon.
