"For an established Underworld like this, it's quite normal to produce a Ghost Emperor, let alone a Yama,"
"If it truly is this type of Underworld, then the situation in the Southern Domain that has just stabilized, I'm afraid it's going to change immediately."
Lu Yuan was clear about his own strength.
If he were only dealing with an Immortal Gate from the Nine Provinces, with the assistance of Qing Immortal Sect and the integration of the Southern Domain Immortal Gates, he still had the strength to fight the opposition.
However, if at this time another Underworld appeared in the rear area, with a Yama within the Yellow Springs Underworld, then Taiping Dao would immediately fall into the awkward situation of fighting on two fronts.
In such a case, let alone holding onto the Southern Domain, even personal safety would become an issue.
