Igor successfully lured Joseph into his World Setting Technique using Joseph's Spirit Power.
To put it simply, he first let Kadi experience their previous argument with Joseph in an illusion. This experience would intrigue Joseph, as he undoubtedly wanted to know the outcome of his dispute with Igor.
By the time Joseph reached Kadi's side, he was completely hooked.
Igor's World Setting Technique had fully unfolded. A new scene would appear before everyone—a scene Igor and Kuren had discovered in the Inner World, something they had specially prepared to show them.
Scenes from the Inner World unfolded one by one. Kuren was truly an excellent artist; his Spirit Paintings were so lifelike they seemed almost alive.
All these scenes were intended for Kadi and Joseph, primarily for Joseph.
