Gu Chen had some doubts, wondering if they had inadvertently stumbled upon the enemy's lair. Why else would there be a vast and towering city like this? Especially with heavy troops patrolling around, this didn't seem like a treasure hiding place, but rather like someone's private territory.
As for the other prodigies, although they didn't speak, their faces were also full of surprise, unable to understand why there would be a gigantic city underground after taking this path. This was nothing like what they had imagined.
Whether it was the Immortal Court or the Holy Court, they were all entering the Immortal Mansion for the first time after all.
However, while everyone was taken aback, they were all also swayed and excited by what they saw.
After all, regardless of the origin of this massive city, it was undoubtedly the treasure of an Immortal Family.
