Mid-stage of the Principle Comprehension Realm

When Tang Yin saw this scene, he scoffed.

The only reason why he was able to slip past the Rou Sect's Array Formations undetected was due to the Heaven Deceiving Art.

Similar to the Heaven Piercing Gaze and the Abyssal Sword, the Heaven Deceiving Art had also evolved.

Contrary to before, Tang Yin was now able to transform into something pseudo-ethereal.

To bypass the Sect Protection Formation of the Rou Sect, Tang Yin transformed into Qi. That's right, Qi!

Before he reached the Principle Step, this was impossible. However, with the evolution of the Heaven Deceiving Art, transforming into something like Qi was possible.

Tang Yin had tried to transform into Qi back when he was in the Mortal Step. But he could not, it was impossible no matter how much he tried.

The Sect Protection Formation of the Rou Sect did not filter out Qi. After all, they needed Qi to flow into their sect for their disciples to cultivate on the mountain.
