Chen Yu paid no attention, and instead pressed quickly with his fingers.
Seeing his actions, a flight attendant hurriedly stepped forward to pull Chen Yu away.
Unexpectedly, the old man suddenly coughed twice, and a black blood clot the size of a quail egg was directly spat out of his mouth.
The old man, whose life had been hanging by a thread, slowly began to recover, and his pale complexion improved, starting to regain some color.
"Sir, you should have your emergency heart-saving pills with you, take six immediately, don't hold them under your tongue, just swallow them down."
The old man nodded repeatedly, quickly taking the pills out of his bag and popping them into his mouth.
"Young man, I can't thank you enough, otherwise I fear I might have..."
Before he could finish, a piercing pain suddenly spread from his heart.
Chen Yu quickly steadied his body, gently pushing on his waist with the palm of his hand.
