Where is the mangá up to at this point? *Spoiler for those that don't read the manga*

After defeating and capturing ceassar the strawhat hat crew (plus Law and Kinemmon) are heading Dressrosa to confront the former Shichibukai, Doflamingo. According to Law's plan, they will use Ceassar as a decoy for Doflamingo. After arriving to Dressrosa, Law's team (Robin, Usopp and himself) are incharge of making the deal on Ceassar with Doflamingo, while Luffy's team (zoro, Sanji, Franky, Kinnemon and himself) will find Doflamingo's Smile factory (Smile are fake devil fruits). But unexpected things happen. Zoro's sword, Shuusui; is being steal por an unknown thief. Sanji, which chased zoro, is getting lost and meet a woman which (of course) he fell in amor with. Kinnemon, who also chased Zoro, is getting found por pirates. Law's team are being found por an orginenzatoin called CP-0. And most importantly Luffy, who found out that Doflamingo has found the Mera Mera frutas (Ace's fruit) and is now setting a tournement to get, cadastrar-se the tournement in which he meet again none other than Bellamy.

Note: Doflamingo needs ceassar so much because he have a deal with the Yonkoh Kido. The deal is that Kido will protect Dressrosa and in exchange Doflamingo will give him Smile fruits (fake devil fruits) which Ceassar invented.

That's about all. Hope i helped
