章 161: Chapter 69: Sneaky Contract! (Seeking investment and followers)_2

Shadow Concealment advanced from Level II to Level III, representing a transformation.

At Level II, Shadow Concealment could completely vanish from sight; the naked eye couldn't detect any anomalies, yet traces of supernatural powers remained during its use.

At that time, Qiuqiu had discovered Snow Blow precisely because of this.

After reaching Level III, Shadow Concealment truly mastered the art, no longer leaving any trace of supernatural powers and greatly increasing its mobility. It shifted from requiring contact with a shadow to move from one object's shadow to another's, to being able to transfer within a certain range without contact.

Beyond Shadow Concealment, Ghost's Flying Knife Skill also advanced to Level III—now capable of using nine knives at once. However, the proficiency level of the Flying Knife Skill did not represent a transformation but rather a quantitative increase, contributing less to the strength enhancement.
