Starting from Blacksmithing at Juyao Pass, Gan Becomes a Martial Saint.

Also known as: [This blacksmith is not doing his job properly! The Dayong Dynasty was at the end of the dynasty. Inside, there were holy places of aristocratic families exploiting the world. Outside, there were a group of enemies waiting to annex them. There were even demons in the sky peeping at Kyushu, ready to destroy the country and destroy the territory at any time. But these have nothing to do with Lu An, who came from time travel. He is just the only blacksmith in Juyao Pass. Responsible for repairing or forging weapons for the demon slayers in the pass. No one knows that Lu An has been working in the iron industry for ten years and has developed an iron frame and an invincible heart. At that time, outside the demon gate, demons invaded like mountains and seas. Lu An killed thousands of demons with a single blow, killing millions of demons with one sword and bowing their heads and retreating. ... Later, the heavenly demon descended and caused a bloody disaster in the world. Lu An stands in front of Cang Sheng with one sword and one sword. "Why do you, a blacksmith from the Demon Rejection Pass, dare to face ten heavenly demons?" "With the sword in my hand, Lu An, I can support the country, control the mountains and rivers, kill demons, rectify the universe, and establish peace!" At that time, Lu An was in chaos, and the blood of the demons was spilled in the sky. But how did he know... The heavenly demon is just a sword raised by the people in heaven, and used to harvest the human world.
