Gu Ze woke up from a nap in another world, carrying a hammer with him. At least it was a feudal dynasty where they spoke the same language. He made a living as a blacksmith and never stopped practicing martial arts. With two ultimate questions on his mind, "Why is this world so much like Huaxia on Earth?" and "Why did I transmigrate here?", he stepped into an amazing martial world. When someone picked up a divine weapon, Gu Ze paused his hammering. "Want it? You'll have to pay." He rubbed his fingers together.
