the conclusion of the arc

The end of the Luffy vs Imu fight. The end of the Zoro vs Sommers and Sanji vs Killingham fights (The ultimate purpose of the fights : won by mastering Conqueror's Haki and surpassing the opponent's Conqueror's Haki so that the excess power took effect). And there are two possible endings: Gaban orders Luffy to flee the island, and they escape, leaving the Adam Tree (the heart of Elbaf) to catch fire and be destroyed. An alternative second ending : Imu is defeated and sent back to the Holy Land via the Abyss Portal.
