Initially, Liu Yan did not pay much attention when he saw that it was an S-grade skill.
After all, Liu Yan now had a bunch of skills, many of which were high-level.
Not to mention S-grade skills, Liu Yan even had many SS-grade skills, and now possessed several SSS-grade skills. Naturally, Liu Yan did not pay much heed to an ordinary S-grade skill.
However, he did not expect this S-grade skill, Cloud Treading Steps, to be so special.
Cloud Treading Steps was also a movement skill that could increase one's speed.
But Cloud Treading Steps was unique. It did not require any elemental powers or even any energy. It was indeed special.
This meant that when using Cloud Treading Steps, one would not attract much attention from the enemy.
Especially during an assassination, Cloud Treading Steps could help one remain concealed.
Additionally, Cloud Treading Steps allowed one to walk in the air, which was very convenient.
