Yeah, i thought this wasn't included in Brook's flashback... Hope Oda starts a new flashback for Gunko next chapter, with a week off before drawing it, ofcourse.
I assume the content of the chest is the Nefertari's family's weapon. Something that must be known by Imu, something that enrages him, he needs to get triggered, i'm tired of seeing him launched to the tree every single chapter, he needs to counterattack.
After this chapter and the following one, can't imagine what Usopp could achieve without being a coward. He needs a flashback about the Boin Archipielago, hope he uses Lily's weapon... another thing that i would like to happen for that weapon is that it's strong enough to carve the Poneglyphs, since Lily was the one that helped to distribute them across the globe, why is she the one that lend her tool to the Kozuki to create them?
