The Thunder Flood Dragon Strongman's actions were swift and surprising to everyone watching.
It wasn't the speed at which the Thunder Flood Dragon seized the Spiritual Pillar that shocked them, but rather how "easily persuaded" it seemed by the Gua Daoist.
At their level of cultivation, few lacked wisdom. Although the Gua Daoist had provided the Jade Scroll and information, everyone remained skeptical, opting to verify things with their own exploration arts after entering the Secret Realm.
Only then would they dare to navigate the Secret Realm.
They did not fully trust the Gua Daoist.
Even upon reaching Treasure Burial Lake, they each showcased their divine powers, conducting their own initial investigations before finally heeding the Gua Daoist's suggestion to join forces.
Never did they expect that the Thunder Flood Dragon would dare to venture onto this so-called "Evil-avoiding Magical Pillar" based on a few words from the Gua Daoist, thus leaving the Treasure Boat.
