Spirit Summoning for All: Only I Can Summon the Heroes of Honor of Kings

I died in an accident while on the path to becoming an esports player, then transmigrated to a world where everyone commands spirits.

You say this world is beset by internal strife and external threats?

Sorry, I have a System! From the start, I awakened the King’s Domain and gained the legacy of every hero!

You say spirit ranks are too low and their damage isn't enough?

Why are all my spirits so powerful? And they even have equipment!

You say leveling up is difficult?

Well, I can use the Possession System to transmigrate into people in other worlds and earn rewards!
