Chapter 1604: Mu Family's Second Daughter

Qingfeng Li refined his immortal level cultivation technique, but also an refined emperor level cultivation technique at the same time. Since he was mentoring the Crimson Fire Viper King, it became very powerful, allowing it to keep knocking the Yellow Sand Demonic Rat King back.

Eventually, the Yellow Sand Demonic Rat King was severely wounded after losing its front paw and it flew away in panic.

The Yellow Sand Demonic Rat King fled very fast within the wilderness, and it suddenly disappeared into the yellow sand. Although the Crimson Fire Viper King chased after it, it could not catch up.

The Crimson Fire Viper King returned to Qingfeng Li's side, then looked at him with eyes full of respect and gratitude.

Because it just attacked Yellow Sand Demonic Rat King with the strategy taught by Qingfeng Li, it clearly felt like Qingfeng Li had a deep understanding about king level cultivation techniques. This person was definitely a hidden master.
