It was a meeting in name, but most of the meeting was just the three family heads listening to the strategy of Lin Fan.
While Lin Fan wasn't a genius, he did have a genius tactician with him in the form of Brainy.
Brainy had already formulated various plans that depended on how many of the royal families would participate, but of course the best scenario was that they would all participate like they had now. Each of the royal families had accumulated resources that couldn't be underestimated and each one that agreed to fight would increase their overall strength.
But of course, the main force of this fight wouldn't be the three royal families. Rather, all they would be providing would be cannon fodder that would clear out the normal beasts of the beast waves.
The main fighters would all be coming from Lin Fan's pet shop.
Lin Fan's pet shop couldn't be judged based on the surface.
