This is... Light Force Treatment!

In the room, wisps of black mist seeped out of the ground and swarmed toward Wang Teng's body. The room was instantly filled with black mist. It looked eerie.

Fortunately, Wang Teng had used his spiritual power to form blockage arrays around the room so that people outside wouldn't detect anything. The only person Wang Teng was worried about was Di Qi.

He was the only one that could threaten him.

However, his mastery of runes had reached the grandmaster level. He was confident that he could escape Di Qi's detection.

Wang Teng used the Lazy Mist Devil Scripture and absorbed the black mist into his body. After flowing around his veins, the black mist gathered in the core of the dark constellation.

Time passed slowly. Approximately an hour later, all the laziness in the battle fortress had been absorbed by Wang Teng.
