In the recent confrontation, Su Chengyu's decision to retreat indeed indicates his intention to consider the long-term strategy.
However, the fundamental reason for this thought sprouted from the means by which the White Tiger Immortal Core resisted his strike, truly reaching the level of a Demon Emperor Realm.
Moreover, it wasn't just an average Demon Emperor level; by occupying the terrain, it transformed the area where tens of thousands of tribesmen resided into the formation's veins, turning the entire White Tiger Tribe into a massive fortress guarding the White Tiger Immortal Core.
Coupled with that pure Heavenly Dao Breath, if Su Chengyu truly wanted to forcefully capture the White Tiger Tribe, it would absolutely not be an easy task.
Without any other intel, defeating the tribe's frontline directly would require at least three or four Demon Emperors of the She Li level.
