I Can Summon an Army of Annihilation

Lu Ping traveled through time. He saw giant dragons soaring in the sky, mages controlling thunder and lightning, warriors wielding swords to defeat thousands of armies, assassins lurking in the shadows...

Fortunately, Lu Ping's golden finger is online, and the endless army of annihilation will drown all enemies!
