Contracting the Fallen Demon Emperor, I Become Invincible!

Ye Ming transmigrates to a world where awakening spiritual power allows one to contract a Saintess or Witch to gain strength. During the awakening ceremony, he unexpectedly chooses the Witch Ying Youyou, who is ostracized by everyone, unaware that she is actually an SSS-level fallen Night Demon Emperor with power far exceeding ordinary Saintesses. Despite facing mockery and doubt, Ye Ming quickly rises using his past life's assassin experience and Ying Youyou's formidable abilities. He sweeps through secret realms, breaks multiple records, joins the top assassin organization Shousha Hall in the Dragon Nation, and with a second-rank body, defeats a fourth-rank fierce beast. He also dominates the martial arts exam in Cangnan City, becoming the number one winner and shocking the four directions.
