The Flowing Cloud Sect

"An excellent martial art indeed, and it's a martial art for hiding. Even though it's a profound-grade technique, I can still cultivate it," Lin Han's eyes brightened.

This Shadow Concealment Technique was truly a treasure.

This meant that if Lin Han mastered it, in Yun City during the night, no one could detect him.

This was an extremely peculiar martial art.

Additionally, hidden-type martial arts required very minimal spiritual energy.

The reason why Lin Han couldn't cultivate certain profound-grade martial arts was the excessive spiritual energy required. However, this concealment technique was different. While it also consumed spiritual energy, it was in very small amounts since it wasn't meant for attacks.

With a sly grin, Lin Han took this Shadow Concealment Technique with him.

With this martial art, no one in Yun City could stop him during the night.

Lin Han then proceeded to look through other martial arts.
