Quick Summary
Ch. 868 KX Launcher

There was two people witnessing Linlin eat the children and Carmel.
One was a giant from Elbaf who was worried and came to see the kids. He returned to Elbaf and conveyed the news about Linlin's panic. This made the entire giant race hate Linlin even more furiously.

The other person was pirate wannabe cook who originally lived on the island, Streusen.
He was the user of the Kuku Kuku no Mi, which allowed him to change anything into the world into cooking materials. He helped Linlin establish the Big Mom Pirates.

End Flashback

Bege and the others face Big Mom and fire the launchers.

Another flashback
Carmel proposed to try to make this place their own country.
Carmel states that if this country exists, then the world will be able to become more peaceful.
After Carmel's disappearance, Linlin resolves to make this country that Carmel rejoiced about.
She came to notice that she could use the Soru Soru no Mi's power that Carmel had used.
Utilizing the Soru Soru no Mi's power, She and Streusen begin their invasion.
End Flashback

Because of the wind pressure and Haki from Big Mom's scream, the launcher bullets are destroyed before they can reach her.
Because of the failure of the plan, Ceasar infiltrates the venue to help everyone escape.
However, their escape mirror also breaks due to Big Mom's screams.
With no place to run, Bege uses his devil fruit powers to transform into a gigantic castle, and everyone rushes into his body for shelter.

Langweilig...das wars mit One Piece ich lass die Finger davon bis der BM Arc vorüber ist. Kein bock mehr auf langweilige Chapter, soweit alles vorhersehbar. Wer hätte gedacht, dass es schief laufen würden, OMG! Bin sichtlich schockiert darüber...

Auf Streusen bin ich ja mal gespannt.

Der ist doch bekannt, das ist der Kerl der die Hochzeitstorte entworfen hat. Erster Auftritt hatte er in Kapitel 858.
