Yen Li was truly scared to death.
This was his Soul Domain, and without his permission, no second person should be able to enter.
Even an Early-stage Primordial Immortal expert might not necessarily be able to break into his Soul Domain, at most they could only destroy his soul.
Yet the existence before him managed to break in without him even being aware—what kind of powerful presence was this?
The most crucial thing was, under the soul presence of this powerhouse, his soul felt an unbearable shiver.
"This... this is a super-powerful existence!" Yen Li immediately made a judgment in his heart.
He couldn't assess the power level of the figure before him because it was beyond his understanding.
Although Wentian Demon Sovereign's soul strength was only at an Early-stage Primordial Immortal Level, his Soul Origin was of the Demon Lord realm.
This suppression by the origin could not be compensated by strength.
"Se... Senior, you... you are...?" Yen Li asked anxiously.
