The Ancient Serpent Merchant Guild, from the outside, appears to have only seven floors.
When Chu Fengmian arrived at the Ancient Serpent Merchant Guild, he sensed that there was indeed an eighth floor in existence. However, the eighth floor of the guild was hidden by some sort of restriction, making it invisible from the outside.
Even when Chu Fengmian entered the guild, he hadn't noticed the existence of the eighth floor.
Clearly, the eighth floor of the Ancient Serpent Merchant Guild was set up by a powerful expert, at least a quasi-emperor. Chu Fengmian only realized this hidden floor upon tracking Hong Mu's movements.
The Ancient Serpent Merchant Guild is far more mysterious than it appears from the outside.
Chu Fengmian's Spiritual Sense had reached close to the eighth floor when he slowly withdrew it, realizing that if his Spiritual Sense recklessly entered the eighth floor, it might be detected by the guild's powerful experts.
