Of course, this was because Dong Tianyu's Companion Spiritual Treasure had already undergone a branch choice and was aware of this evolutionary branch.
Now, those who equipped instruments and modified the interior space of the Companion Spiritual Treasures didn't know about this matter.
And if it were merely the installation of some equipment, it might be alright, but for those survivors who decorated the interior space of the Companion Spiritual Treasures, unless they controlled the size to remain unchanged, neither expanding nor contracting--
Otherwise, unless the modifications were simple, any size changes in the Companion Spiritual Treasure due to devouring Mysterious Cores would definitely cause irreversible damage to the installed interior space.
However, even so, there are still many people who, after feeding the Companion Spiritual Treasure Mysterious Cores to reach a certain size, would then modify and enhance its interior.
