This Sect is Obviously Very Powerful But Overly Cautious

The Qi Training Sect is an ancient and mysterious sect. It's said that its disciples and elders are all at the Qi Training stage. Due to its weak strength, it's largely ignored, making it the oldest sect in the world. Everyone considered it a minor, insignificant sect. Until one day, a devastating natural disaster struck, and the seventy-two Qi Training Sect elders finally gave up their concealment and unleashed their immortal-level cultivation.
