Although they were initially bewildered when someone in the crowd began to give directions, it wasn't long before they all caught on. So before they arrived, they already had their suspicions; the reason they came in person was to verify their own thoughts.
From above, Zachary could clearly see the situation on the ground where the black snakes deliberately avoided the location of the Companion Spiritual Treasures.
Even before the crowd on the ground discovered the function of the Companion Spiritual Treasures, Zachary had already known this would happen.
After all, Mr. Thompson's parents were still inside the Companion Spiritual Treasure, and the black snakes weren't just appearing around the crowd; they were spreading throughout the entire camp.
Compared to a group of unfamiliar strangers, when predicting danger, Zachary would naturally focus first on his parents' location, ready to act at any moment to protect them.
