Killing People’s Hearts?

Killing hearts!

The words of the Ultimate Killer King were like knives that wanted to pierce through Feng Lin's soul, slaughtering his heart.

He laughed gloomily.

"Among all the martial arts in the universe, all of them can be countered. Only what exists in the heart cannot be broken. No matter how powerful a technique is, it cannot be compared to killing the hearts of people. As the medical technology is already extremely well-developed, as long as medical treatment was applied in time, all kinds of grievous injuries would be healed. There's only one flaw...if the heart of a person died, no medicine would be able to save him. Even if his body was saved, he would be nothing more than a zombie. So what does it take to kill the hearts? I've massacred countless people, how can you even begin to comprehend the concept of killing hearts? And now you actually dared to fight me, truly courting death!"
