When Dong Tianyu fed the Blood-Colored Mysterious Core to his Companion Spiritual Treasure, it was uncertain whether the Companion Spiritual Treasure was bound to enhance the material of the ship's body by devouring the Blood-Colored Mysterious Core, or if the core that Dong Tianyu fed this time was noticeably larger.
In any case, after the Companion Spiritual Treasure devoured the Blood-Colored Mysterious Core, the material of the ship's body was upgraded again, perhaps because Dong Tianyu had already upgraded the jade material once, so this time there was no option to change the material.
This upgrade of the ship body's material endowed the Companion Spiritual Treasure with a new entry for energy absorption.
Unlike Energy Gathering, which passively collects surrounding unstructured energy, Energy Absorption could actively absorb energy attacks, energy shields, enhancement buffs, debuff buffs, and other sustained curses released or controlled by others.
