Qin Fengming had not done anything to Old Man Zhang at the time. He had merely let him enter the Divine Machine Mansion and meet Elder Li and the other elder. With his knowledge as an early Ghost Lord cultivator, there was naturally no need to explain anything; he could guess part of the truth on his own.
Old Man Zhang had also been present at the time, so he had seen clearly that Lord Meng had sealed the magic power of Elder Li and the other elder.
Although Old Man Zhang did not know why the two men had vanished the moment they touched the ground, he had clearly seen two mid-stage Ghost Lord cultivators use the Earth Evasion Technique to pursue them.
From the moment those two mid-stage Ghost Lords entered the rocky ground until the cultivators of the Three Dao Sect appeared, they had never shown themselves again.
And now, seeing the two men who had originally had their magic power sealed by a Great Cultivator standing before him unharmed, Old Man Zhang immediately understood. The young cultivator he had captured with that bizarre movement secret technique was undoubtedly a Great Cultivator from the Human Realm.
Faced with a Great Cultivator—with death itself before his eyes—Old Man Zhang instinctively submitted.
This was not because the Ghost Realm cultivators lacked backbone. Rather, before an overwhelming existence against whom they had not the slightest power to resist, anyone would react instinctively in the same way.
It was like facing a desperate situation that one had no way to change, able only to watch helplessly as death drew slowly nearer, without the slightest power to resist. It was not that one did not want to resist, but that one was powerless to do so.
What happened afterward was much simpler.
