After he left the Archangel Fleet, he immediately used "Light Energy Transmission" to reach the space station.
After a series of hair-raising yet harmless explorations, he found the main brain controller sealing the essence of the Assassin Angel in the dead center of the space station.
This device covered over a thousand square meters, completely crystalline, like a giant transparent crystal brain.
The body of the Assassin Angel was surrounded in a purple-black fog, floating in front of the crystal brain's forehead.
Its body was entangled with silver-white luminous chains.
These luminous chains somewhat resembled the crystal brain's neural fibers.
One end of the chains wrapped around the Assassin Angel's body while the other end connected to the cerebral cortex of the crystalline brain.
From direct observation, the first step to help the Assassin Angel escape was to remove the luminous chains on Him, setting Him free from the constraints of the crystal brain.
