Elvis had slowly become used to Gu Mengmeng's uniqueness and how she did not understand much of the basic knowledge in the Beast World.
So Elvis explained while enjoying the feeling of tenderness from hugging Gu Mengmeng, "It acts as a form of protection for a male's mark to be left on the female. When you encounter danger or difficult situations, just hit this mark hard and I could sense your position, run over to you and rescue you."
Elvis used his finger to point at the mark on Gu Mengmeng's collarbone and said, "It is connected to here."
Gu Mengmeng looked at her small hand covered by Elvis's hand on his chest and felt warm. She smiled sweetly and rested her head back into his arms, placing her face sideways on the back of his hand to feel the affection and contentment.
