Under Lu Chuan's control, Invisible One slowly emerged from the group of Corpse Puppets.
The abilities of Invisible One are unquestionable, a perfect assassin-type zombie.
With powerful invisibility, it can secretly infiltrate the enemy's side area and deliver a fatal blow.
Then, Lu Chuan fed four fourth-tier Crystal Cores to Invisible One.
One by one, the Crystal Cores were swallowed, and the originally solid cores instantly transformed into abundant energy, akin to boiling water, crazily surging within Invisible One's body, producing a slight sound of water flowing.
After a moment, the intense pain caused Invisible One to tremble uncontrollably, and its smooth, pale skin began to crack, revealing blood-colored lines like webs across its body.
As the energy helped Invisible One begin its transformation, Invisible One's aura started to slowly rise, advancing toward the fifth tier.
