Summary, thanks to redon from Arlong Park Forums.
Chapter 1,040 summary, it's a short chapter (15 pages). As I told you, I haven't had enough time to write a long summary as always. Sorry if some parts are not much detailed.
Chapter 1,040: "Words that has no effect on New Generation."
Germa 66's Ahh… Emotionless Excursion, Vol. 4: “A being beyond science”. Niji and Yonji remember how Big Mom defeated them.
Big Mom manages to withstand Kid's attack from the last chapter. She then smiles and uses “Life or Slave” to pull the lifespans from everyone around her. Those affected must give her 50 years of their lifespans or they will become Big Mom's slaves.
Big Mom begins to take away the lifespan of some members of Kid Pirates and Heart Pirates but Law manages to stop her. Kid and Law stand between Big Mom and their nakamas. Big Mom tries to take away their lifespans too, but it has no effect on them.
Kid: "There's no need to be afraid of an old lady who is about to die!!"
Law uses a new technique called “R Room: Silent” which is inspired by Corazón's Nagi Nagi no Mi power. With it, Law creates a sphere around Big Mom that blocks the sounds she makes. This prevents Big Mom voice reaches their nakamas or Kaidou's subordinates.
Law: "This move erases all noise you create!!"
Kid keeps shooting his “Damned Punk” at Big Mom until the floor collapse, Big Mom begins to fall. “Misery” tries to help Big Mom but Law cuts it down with his sword (without using Ope Ope no Mi power).
Big Mom falls and reaches the basement armory, taking with her the bombs that Yamato froze and even the Kazenbou. Big Mom tries to grab something, but accidentally punches one of the frozen bombs, which explodes. The explosion destroys part of the lower area of Onigashima and the Kazenbou. Big Mom falls off the island.
Big Mom calls her Homies to help her, but the sphere created by Law prevents her voice from reaching them. As Big Mom falls from Onigashima island, she thinks about Gol D. Roger.
Big Mom: "Roger, why did you make that kind of announcement before you died!?
Now I have to live with all these young pirates coming for my head!!
Why didn't you just say it before you die, Roger!?
What exactly is One Piece!!? And where is it!!?
Is it in “this country” as well!?"
We see the reaction of some characters in Onigashima to the explosion. Zoro falls when island shakes (no sign of grim reaper). Orochi wonders what is going on. On the 3rd floor we see that the battle between Raizou and Fukurokuju is ending. Fukurokuju is lying on the ground screaming and asking for water, Raizou is still standing.
Big Mom falls into the hole Law's attack created in Wanokuni along with the bombs. As she falls, Big Mom says a few last words.
Big Mom: "Damn you, Kid... Law... Don't you dare think I'm going to die this easily!!"
When Big Mom looks up, a huge explosion takes place inside Wanokuni's hole. Big Mom disappears in the middle of the smoke. The explosion is larger in size than the Flower Capital, but thanks to Law's technique, the sound of the explosion doesn't reach the city.
Narrator confirms that Law and Kid are the winners of the battle, their crews celebrate the result.
Cut now to Yamato and Momonosuke, both are talking through a huge hole at the bottom of Onigashima created after the explosions.
Momonosuke: "Yamato! I need to tell you something! Zunisha is near this island!!"
Yamato: "What!? The elephant that appears in Oden's journal!!?"
Momonosuke: "Yes!! It's Joy Boy's nakama who committed a crime 800 years ago!!!"
End of the chapter. Break next week.
