On the road of the city of Teotihuacan, there were a lot of rare symbols all over the place and a lot of angels and demons who used their magic to operate the portal.
Flavio was taken to the central part where the portal would be activated, all they needed was that the portal is activated in the other world.
Hellena knew that the portal on her husband's side had been activated, so with the help of a large part of her family and Flavio's, the portal began to be energized.
A large number of gods descended from Zeus came to Apollo's call for the activation of the portal, ironically Apollo preferred to stay in his room because he did not want problems with Ra due to his wife's pregnancy on his part.
Ra could not be angry with his wife because if he did his children could kill him but that does not mean he does not want to see Apollo and fix things.
