After Julian secured Dragon Four's Devil Fruit, he resumed training. The Flame Dragon Pirates' ship had already sailed the Sea for seven days and seven nights. The seas had been unusually calm during those seven days, without any raging waves. Throughout the voyage, Julian kept up his daily training to improve his strength. His Observation Haki felt as though it was nearing a crucial moment.
Every day, Julian returned to his room with his head covered in bumps. After dinner, his head would recover, and he would continue training his Observation Haki. He always felt that something was wrong with his Observation Haki training, as if something were missing. Julian suddenly thought of something and said, "Heavens, I'm willing to trade five hundred years of Momonosuke's lifespan for the awakening of my Observation Haki. If that isn't enough, add another five hundred years from Saint Saturn. Bless me, you dumb bird king, Kozuki Oden."
With that, Julian continued training and said to Herbert, "Old Sen, you need to hit harder so I can awaken my Observation Haki, got it?" Herbert nodded heavily and said, "Rest assured, Captain. I will help you develop your Haki as soon as possible." Then he activated his Devil Fruit ability and unleashed a slash. The wooden stick in his hand was coated in sharp sword energy, and Julian sensed the slash closing in from behind.
It hurts too much, dodge! Julian thought. His Observation Haki's range behind him seemed to awaken on its own. He instantly tilted his head, then grabbed the descending stick with his right hand. Julian had finally awakened Observation Haki at the most critical moment. He burst into laughter.
Then he laughed and said, "Sure enough, Momonosuke's hundred years of beast life really work. Bah, what lifespan? It's clearly dog life."
