Leon didn't know the details, but it looked like some scientists managed to make the engine of the chopper be able to absorb mana from the surroundings. However, it had to absorb mana for twelve hours to fill the tank. Although the chopper's tank was already full, they decided to leave it behind since they would use that to go home. It would be the best option to use the chopper in case some group find and tries to chase them. Even though Leon could make everyone fly at fifty meters per second, he couldn't make them invisible.
"How many guards protect the relic?" Leon asked while they were flying to Rome.
"Only ten, in fact, they protect the entrance of the treasure room," Betty explained. " The treasure room is entirely made of steel... you said you could make holes in wall and floor using earth magic, but can you do the same to steel?"
"Don't worry about it; I will open the path to the treasure room," Leon said.
