He neither attacked nor ran away? Quite cautious indeed.
Feeling the heartbeat on the main stage that was getting faster but still not moving and staying in place, an old man among the guests, dressed slightly shabbily and with a face full of pain, raised an eyebrow in surprise.
His ability temporarily "enhanced" the heart of everyone within range, accelerating their blood circulation.
If the opponent became overly tense or retreated immediately when sensing danger, the enhanced heart would receive double stimulation, causing the blood flow to surpass the body's limit, rendering them incapable of resisting.
In simple terms, the faster someone moved within his ability's range, the quicker they would fall, just like the two old men from the Ryan Family.
