They could disregard the Longevity Sect and the Nine Nether Mansion, but the Heaven Fiend King and Life Killer King behind them were peerless experts comparable to second-stage Weapon Masters with five Bloodline Awakenings.
Even the White Tiger Aristocratic Family would not easily become enemies with such an expert.
"The Heaven Fiend Demon Technique is a cultivation technique created by the Heaven Fiend King based on his demon bloodline and half of the Heavenly Saint Sect's Supreme Star Technique. I once heard the ancestor mention that there are hidden dangers in his cultivation method. It seems that he conducts cultivation methods and human body experiments all year round to perfect the Heaven Fiend Demon Technique. This Lu Yingxuan should only be one of the many experiments," Murong Qi pondered and said.
