How could there suddenly be a stranger's heartbeat in a space?
There's only one explanation, and that is this person had already hidden in this space in advance, using an extremely skillful concealing technique to remain undiscovered, making themselves like a lifeless stone hidden here.
Even someone with extraordinary spiritual sense like Jiang Dali would naturally assume this "stone" was supposed to be here and subconsciously overlook it.
However, a person is always a person, possessing life, thoughts, and consciousness, impossible to be as lifeless as a stone with no hint of awareness or vitality fluctuation.
When there's the slightest change in their awareness or vitality, it's like a pebble falling into the water; even the slightest disturbance will create ripples and alert the person in the water.
