Short Summary
Luffy fights Wiper, but after some time, he falls into some "underground ruins". Meanwhile, Enel appears on the Going Merry and after telling that his true goal was the City of Gold, he takes out both Usopp and Sanji; then he vanishes and leaves Satori's brothers Hotori and Kotori to avenge him.

Long Summary
Usopp crying that Sanji was dead was listening for his heart beat on the right side until told by Nami that he needed to check the left side. On doing that, Usopp became relieved that Sanji's heart was still beating. at that point, Usopp challenged Enel saying he has 8,000 followers and will spare Enel's life if Enel leaves. Enel, upset at Usopp took him out as well with a blast of lightning. Enel then told Gan Fall that the Enforcers he seized have been working long and hard for six years and the end of their labor is close to finish. He also told Gan Fall tht his need for Sky Island is also complete. Enel stated that the people of Skypiea are ignorant in seeing the Upper Yard as only a land of Vearth. He stated that the SHs, his crew and the Shandians all seek the City of Gold.

after his discussion with Gan Fall, Enel left saying he is also a partaker in the final game and responded to Gan Fall's inquiry about his Enforcers leaving Enel's forced labor as something only God knows. at that moment,
