I Am Yang Guo, and I Grow Stronger by Helping People Master the Evil-Resisting Swordplay

“Your Nine Yin Manual may be the best in the world, but it’s still only number one under heaven. I have a sword manual here that can make you ‘number one in the universe,’ even better than number one under heaven!” “Number one in the universe?” Ouyang Feng tilted his head. He had clearly never heard the phrase, but he understood the words “even better than number one under heaven.” He immediately began stamping his feet in excitement. “Where is it? Where? Son, show it to your father!” Ouyang Feng might be mad, but he had no resistance to powerful martial arts manuals! Yang Guo took a deep breath and steeled himself. The old man was crazy anyway, so even if he practiced the Sunflower Manual and something went wrong, Yang Guo couldn’t be blamed. He raised a finger and gently tapped Ouyang Feng on the forehead. [Ding! Sunflower Manual transmitted!] As soon as the System’s notification sounded, Ouyang Feng suddenly cried out, clutched his forehead, and stumbled backward, eyes wide. He muttered, “To practice this art, one must first castrate oneself… To practice this art, one must first castrate oneself…” He repeated those eight words over and over. His face flushed, then turned pale, until suddenly he slapped his thigh. “Excellent! What a manual! So ruthless! So powerful! No wonder it’s number one in the universe!” Yang Guo nearly fell to the ground in shock. The crazy old man actually thought it was good? Ouyang Feng grabbed Yang Guo’s hand, his eyes shining. “Son, this sword manual really is powerful! It’s far more ruthless than the Nine Yin Manual! Your father’s going to practice it right now!” Seeing him charge toward the door, Yang Guo hurriedly stopped him. “Father, where are you going?” “To find a knife!” Ouyang Feng declared. “I’m going to castrate myself!”
