The Magician of Seraphim

A thousand years ago, a hundred-story tower descended from the sky. God ordered all races to climb to the top of the tower through challenges, otherwise all races in the world would cease to exist in a thousand years. Today, 900 years later, people have conquered ninety floors of the tower. But in these years, the overt and covert struggles within and outside various races have become increasingly intense. And can Luo Yu, a candidate with dreams, join the "Heart of Gears" academy established to climb the tower and create his own glory in this turbulent era? The pace is slow, unsystematic, and the foreshadowing is intensive.
