Of course, Lin Mingyuan knew that the monsters from the other world didn't possess what humans call "emotions," which could only prove that the Black Tide's terrifying obsession with Xing Jie saw the young girl as the only medium currently capable of allowing its descent into reality.
Lin Mingyuan's attempts were not completely without effect.
According to his experience, after dozens of experiments, the Black Tide was indeed becoming gradually "softer."
It seemed to realize that the girl's frail human body couldn't bear an overly vast power; thus, to have a platform capable of communicating with reality—"Intrusion into the Human World"—which is nearly the only impulse of the Far Realm's supernatural forces—it was indeed slowly changing its way of interacting with the medium.
In other words, while the Black Tide lacked emotions, it did possess a mechanism akin to "reason" or "thought."
