Luffy now has telepathy abilities lmao...
Nothing is inconsistent my friend..
Luffy and Momo both can hear voices... this was shown for Luffy in Fishman island and in Zou with Momo... so just like Momo can hear voices on rooftop... Luffy can hear others...
The difference is Momo can give orders to creatures while Luffy cannot...
Regardless.. Luffy used that ability of him hearing Momo and Momo hearing him back in order to convey a message to Momo.. because the message was so necessary as many soldiers in alliance were starting to lose hope and morale in the fight... it’s also the reason Kaido wanted Bao Huang to announce his victory.. because he wanted the enemy to surrender by losing morale..
Which was shown in this chapter itself as people started to question if there is any meaning to continue fighting
the only thing I am impressed with is Luffy taking advantage of that ability he has with Momo... he never looked that smart to do such a thing honestly
