Yu Xuanyi and Yu Cheng both felt a bit emotional.
At this moment, Yu Yunqing's eyes flashed with confusion. "Even Immortal Kings find it so difficult to delve deep into this area. How did those Jiuyou Cultivators manage to pilot the celestial ship and venture into this region?"
Upon hearing this, both Yu Cheng and Yu Xuanyi, and even Lu Yi, paused slightly, adding more doubt in their hearts.
"Indeed, those Jiuyou Cultivators shouldn't have reached the Immortal King Realm. Even if each of them is an Immortal Venerable, they couldn't easily come and go in such a region, could they?" Yu Xuanyi murmured to himself, somewhat unable to understand.
Yu Cheng thought for a moment and spoke, "Perhaps they have mastered some unique method of entry and exit?"
"That might be the case." Lu Yi also nodded slightly.
