Zachary Dong never expected that a mere low growl from Grayson Todd could directly repel those intruders.
Initially, Zachary Dong and Robinson William, who had no specific sense of what the Grandmaster Realm entailed, suddenly had a concrete concept of it at this moment.
Zachary Dong walked the path of Cultivation and had even stepped onto the invincible route of the Nine Refinements Golden Core, naturally having no concept of the Grandmaster Realm of the Martial Path.
Meanwhile, Robinson William, who was Grayson's roommate before the Natural Disaster, and despite only recently reaching the Path Entry Realm in his Cultivation, didn't feel Grayson's Grandmaster Realm's might due to Grayson intentionally suppressing his aura.
The reason Grayson concealed his aura from the start was that upon arriving, he encountered Dong Tianyu who was in Sword Flight, and soon after, his former roommate Robinson William appeared.
