Where to find vorabook

I came back to neo monsters after quitting a year ago. With a new account

The game pretty much progressed so much since last i played. It is said you can get vorabook from special ingredients mission. But i cant seem to find it, can anyone tell me? My team cant fight events yet but i really want to evolve my legend that require vorabook xD

That specific event is currently locked and will be available on 18 of this month.BTW welcome back to the game

Oii, welcome back lol

Hi old clanmate

Thanks
