The strange feeling arose the moment Ji Dong's Soul Power entered Ah Jin's Soul World.
In fact, Ji Dong didn't realize that what he was doing was extremely dangerous. If Ah Jin's soul resisted, his soul would inevitably collide with Ah Jin's. The outcome could very well be his soul devouring Ah Jin's. Even if he realized in time, it would bring irreversible damage to Ah Jin.
Luckily, Ah Jin didn't harbor any substantial resistance towards him. Ji Dong's Soul Power was overwhelmingly stronger. Before Ah Jin's soul could even respond, he had fully invaded her Soul World, voluntarily completing the Soul Communication. What Ji Dong didn't realize was that by doing so, he was temporarily injecting his soul into Ah Jin's. Regardless of how powerful his soul was, after his departure, there would still be soul impressions left in Ah Jin's soul. Such that, whatever happened in the future, an image of him would always reside in Ah Jin's soul, and there would be no resistance against him.
