King of Explosives nodded, sighed, and said, "When I was young, I didn't understand and I thought that once I went out into the wide world, I would be able to carve out my own career to show off when I returned. But no matter how vast the world is, it's not easy to survive in. At last, I was able to return only to find my mother had already passed. How I wished to properly show her filial piety, but she couldn't wait for my return. Sometimes, I often think, if I hadn't left back then, if I had stayed by her side, I wouldn't be filled with so much regret now."
