Thor's Promise flickered. In the next moment, the massive Thor appeared out of thin air. Lan Jue placed the Spiritual Simulation Generator and the Blinding Stone into Thor's core and made some simple adjustments.
After Thor was modified by Jue Di, Jue Di equipped it with something called the Heavenly Heart Pool. The Heavenly Heart Pool was an integral part that could accommodate any Power Gem and allow it to utilize its powers to the max.
When the Blinding Stone was placed inside it, Thor could become invisible. The Spiritual Simulation Generator was relatively more troublesome, but Lan Jue had already done some modifications to Thor's programming, so all he needed to do now was install it into Thor.
Coupled with his own psychic powers, using the Spiritual Simulation Generator to conceal Thor was much easier than concealing a spacecraft. It was also much safer.
