When Eggy got in touch, the Blade Warrior seemed to forget all past grievances, gently coaxing information out of it. Where did this thing specifically come from?
Eggy didn't hide anything and told her honestly that the Light Crystal might have been casually taken by Feng Yi from the Light Gate of the Magic Crystal civilization because, before he fell into a deep slumber, he had seen this object in the records of the Magic Crystal civilization's gate. Therefore, Eggy guessed that Feng Yi must have taken more than one piece. Knowing that guy, he probably took at least three to five pieces, or as many as dozens, possibly all tossed into some obscure corner of the Space Crystals, which is why they had not been discovered.
