Transmigrated by Accident

A random 17 year old was transmigrated to the world of Golkindarr; where magic is reality. As he arrived the lord of the realm realized he made a mistake and granted him with 1 wish.
He wished for a system, and now he embarks on the path of cultivation, with a goal to bring all his friends over to join him on a grand adventure for the ages, and because it'll be more fun.
