I Became a Saint, So Why Are You Still in the Tutorial Village?

Zhang Shuo transmigrates to Blue Star and discovers that its Altar of Destiny can take people back to ancient eras. His classmates all choose the ancient era, renowned as a golden age of cultivation. Zhang Shuo alone chooses the Desolate Era, where no one survives. No one knows that the so-called golden age of cultivation they chose was actually opened up by Zhang Shuo in the Desolate Era. One person travels to the Near Ancient Era and returns as a grandmaster of martial arts. Another goes back to the Middle Ancient Era and returns having just formed a top-grade Golden Core. Someone else transmigrates to the Upper Ancient Era and returns with a divine godhead. Only when Zhang Shuo returns from the Altar of Destiny does everyone suddenly see purple qi stretching thirty thousand miles from the east!!!
