Yesterday, I received a short essay planned by Dream Pointer. I was too busy at work and forgot to download it (this is how social animals look like. After watching the animation demonstration when downloading, Luffy's "Ape God Gun" in third gear is indeed accurate, but I am a little curious about what happens next. How do you release the combined attack skill? Is it the effect of Sanji's blue card? After passing the novice level, I saw Zoro and Nami's yellow cards. They are auxiliaries that tend to increase and debuff, so the blue card is the secondary C? ? Does anyone know how to answer it?

ps: I would like to call the storyboard in picture 2 a world famous painting"
