Blonde Monster
The liver was one of the largest organs in the human body and the largest of the human abdomen. It was located on the right side of the human body. The liver was one of the most important organs, so if it was damaged, it would be difficult for a human to maintain his life.
A blow to the Liver was not necessarily going to destroy it. But a blow to the liver would make the soft and elastic object expand to the other side. It was like a balloon filled with air that was pressed firmly on one side, causing the wind to force the other side of the balloon to inflate.
By expanding the other side of the liver, it signalled various internal organs to react. The ones that get the biggest impact were heart rate, respiration, and blood vessel flow.
A normal adult male, in general, was capable of delivering a punch of about six to eight meters per second speed. It was capable of dealing a large shock, or even a certain amount of damage to the enemy's Liver.
