These two wandering spirits, one tall and one short, exhibit a very peculiar existence.
Moreover, they cannot be killed permanently and seem to have the ability to revive infinitely.
The current cultivation and strength of Yan Xiaoru are at too much of a disadvantage when fighting them.
Going toe-to-toe in a direct confrontation is a losing battle, but using heavenly thunder would be an extravagant waste.
A single strike of heavenly thunder, costing 1000 incense value, is incredibly powerful; using it to kill two wandering spirits is like using a cannon to swat mosquitoes.
Aside from heavenly thunder, Yan Xiaoru temporarily has no other means to deal with the two wandering spirits.
As a result, these two spirits are like persistent plasters, constantly following and being a nuisance.
But at this moment, as Li Muyang watched the two wandering spirits passing by on the street below, a sudden idea struck him.
