The children tell Caesar that their heads hurt and he responded by telling them to go back to the biscuits room where there is more candy for them to eat. Mocha begins to regain her senses.
Vergo and Monet are waiting for Caesar. Caesar arrives and tells Vergo to keep Smoker in check. Vergo tells him its too hard to keep Smoker in check. It is revealed that Caesar made a deal with Law in the past to give his heart to him and in exchange he will get to keep Monet's. Caesar squishes Law's heart after Law gives a retort. Caesar is about to squish Smoker's heart when Monet stops him telling him that the broadcast is ready.
Caesar is about to give Smiley the big giant candy which is a weapon called Shinokuni. Zoro's group is still running away from Smiley. The dragon escapes from the sled and Caesar tells his subordinates to take off their suits and run to the lab. Smiley eats the giant candy and Chopper wonders what is happening while watching the broadcast

The Deadliest Weapon of Mass Destruction in History! Shinokuni!

After Smiley swallows the oversized candy, the candy coat dissolves revealing a special drug designed to convert the entire content of Smiley's body into a "perfect" weapon of destruction, Shinokuni. In the process, Smiley dies and in a sack of apples, an apple turns into a Devil Fruit. The beast's body transforms into poison gas spreading quickly throughout the island. It's lethal power was demostrated when Caesar's men were caught in it, being petrified before the eyes of the Brokers and the captive Straw Hats. Zoro's team are seen desperately trying to outrun the approaching gas while Nami and Usopp help Brownbeard after their vicious attack by Caesar. At the Lab, Ceasar reveals to his captives that they will get to experience the poison gas as well, moving them outside dangling in a cave. In spite of their situation, Law told Luffy that their original plan will still carry on and that its time to strike back at Caesa

The Counterattack Begins! Luffy and Law's Great Escape

As the Underworld Brokers watched the video feed of the captive Straw Hats and Marines, Eustass Kid and Killer decided to ignore it for more important matters, such as forming an alliance between the Kid pirates, On Air Pirates and the Hawkins Pirates.
Law then decided to set his plan into motion and orders Franky to blow a fireball at a destroyed ship, creating enough smoke to block the cage from being seen from outside. Law then breaks free, explaining that he switched the sea prism stones with fakes during his stay on the island, and proceeds to free the others and restoring Tashigi and Smoker in their own bodies while securing their aid. Franky however had to leave them and protect the thousand Sunny. Meanwhile, Zoro and Nami's group are still running away from Shinokuni and they manage to join up while escaping. Luffy's group managed to enter the Lab with the aid of Law and they opened the gate, allowing the G-5 marines to get in before closing the gate, but the rest of the Straw Hats were still outside. Seeing their only chance of hope closing, Zoro and Kine'mon effortlessly cut the gate open, getting everyone inside safely.

The Aim is Building R! The Pirate Alliance's Great Assault!

Though the Straw Hats and Brownbeard managed to escape into the lab, they left behind a gaping hole. But they soon realise that Shinokuni can now enter the lab. The G-5 Marines panickly seals the hole back up with various wooden and metal planks. They succeeded in sealing the hole as Shinokuni proceeds to spread throughout the island. Brook uses the power of his Devil Fruit to become a soul and survey the area outside of the lab, noting that 'it was like the land of the dead'. After regaining their senses, the G-5 marines then turn their guns and swords towards the Straw Hats preparing to arrest them. Nami notices Law and demands him to switch back her's and Sanji's body, to which Sanji secretly refuses. Law agrees to return them to their original bodies and uses Shambles to switch their hearts back. Nami notices that she was wearing a different coat and punches Sanji, accusing him for peeping at her body. Law then explains to everyone present that they only have two hours to escape, he then continues by saying the only passage that leads safely leads out of the island is called R-66 and is found in Room R. The marines were reluctant, but quickly changes their mind when Smoker repeated the order to them. Smoker then orders Tashigi to take command of the men and rescue the children as he goes to confront Vergo. Meanwhile, Caesar Clown is celebrating the deaths of his victims but notices that the cage has no solidifed bodies, which he needed to prove the power of Shinokuni. He also notices the absence of the G-5 Marines. Vergo states that Luffy and the others must have broken out of the cage and helped the G-5 soldiers escape. Before Luffy went to fight Caesar again, Zoro calls out to Luffy reminding him that this is just the beginning of the New World and he mustn't let his guard down again, and Luffy happily complies as he plows through the Satyr soldiers. Caesar Clown then receives the news that the Straw Hats and Marines have broken into the Lab, leaving him alarm
