Zhang Feng, however, treated the thief's brain as a storage device in the dream's 'concretion' and extracted everything at once.
The reason for calling it 'dream concretion' is that a dream is a virtual emission of thought, a state where the brain is unconsciously defenseless.

Zhang Feng can easily achieve a 'frequency' connection with the dream through the spiritual characteristics of the Primordial Spirit's concretion and extract the data within the brain.
Of course, usually, when observing others' thoughts, it's the same, but not as convenient, detailed, and vivid as in a dream.
Just look, in the dream, he's about to flay the thief, and the thief passed out from fear several times in the dream, how real it feels.
Especially in general circumstances, a person can wake up.
Like when falling from a building or encountering something terrifying in a dream, one wakes up suddenly.
