The man in sunglasses stared at his opponent's back. He had already lost count of the number of times he had experienced something similar to this. As if he were programmed, he launched a punch as he always did in this situation. The goddamn instructor's voice seemed to echo in his ears. "Ten centimeters into this spot is the enemy's heart. As long as you have enough strength, you can make the enemy's heart stop with a single punch!" "This spot contains the enemy's spleen. If you want to delay the enemy's death for ten hours, strike this spot with 70% of your full strength. After that, the enemy's spleen will slowly rupture due to coughing and vigorous activities, and his blood will fill his abdominal cavity within an hour!" "Do you see this rib? Now look at my hand. Clench your fist like this! Strike this rib with your slightly protruding middle finger, and the broken rib will pierce into the enemy's lung, causing hemopneumothorax. No matter how powerful the enemy is, he'll become a sheep waiting for slaughter after that! " "If you want to give the enemy a lifetime of suffering, attack this part of his spine. That's right! He'll become incontinent, impotent, have bedsores and will remain bedridden for the rest of his life! " "....." A flurry of storm-like attacks struck the enemy in front of sunglasses guy! In this moment, he felt that his attacks were perfect, flowing smoothly out of him like water. He felt that his skills had reached a new height! It was easy for him to kill someone, but to beat a person to the brink of death and yet not crossing that final line, like he was doing now, was a level of perfection. It was the first time he had managed to achieve this!
