While regret and fear filled Master Bell Mountain's heart, Lin Mu and Little Shrubby stabilized themselves.
Both of them had expended a lot of energy in killing Master Cull Mountain after all. Little Shrubby especially had to exhaust even more energy due to the fact that he was already in the Seven Beasts Burst form and was directly using the power of his Dao Embryo.
Normally, killing an Immortal Ascension realm expert, even with the pure power of a Dao Embryo like that, was not possible. It was actually Little Shrubby's unique Dao Embryo that allowed this to be possible.
The Dao Embryo erupted with flames that were like the flames of hell, directly burning away the old woman as well as her Nascent soul, not letting her have a chance at escaping. The flames even used her own energy and spirit Qi as the fuel.
This left Little Shrubby with no body nor soul to consume, but it was a cost that they had to accept.
