Chapter 1040, One Piece Wiki

Chapter 1040 is titled "Wasted Words on Young Ears". Germa 66's Ahh An Emotionless Excursion, Vol. 4: "A creature beyond the power of science" Niji and Yonji think about how they were defeated by Big Mom. Big Mom withstands Kid's laser blast and tries to use Soul Pocus, which fails to affect Kid or Law due to their lack of fear. Law then creates a soundless area (much like Corazon's Devil Fruit power) around Big Mom, and as Kid forces her down a hole, Big Mom is left unable to call her homies
