After Ten Years in the Logistics Department, I Am Invincible

I, Chen Xuan, am a handyman at Zhujian Hall, Logistics Department of Tianjian Sect. Spiritual root rating: inferior. Daily job: Swinging a sledgehammer. Before time travel, he was a precision casting engineer, but after time travel, he became a firemaker at the lowest level of the Immortal Sect. Everyone said that I had no chance of immortality in this life. Even the outer disciples had to pinch their noses and take a detour when passing by the Sword Forging Hall. But they don't know that I can become stronger by blacksmithing. With every swing of the hammer, a ray of source energy enters the body. Tempering the physical body, deducing the skills, and transforming the cultivation level. Others narrowly escape death in the secret realm, but I am as stable as an old dog in front of the stove. The genius of the outer sect took pills to break through the foundation, and I quietly tempered my body to copper skin and iron bones. Ten years. A whole decade. Watch the furnace, control the fire, swing the hammer, and temper the sword. The sect has had three outer sect chiefs, the devil has come in and been beaten back, and the secret realm has been opened and closed again. The fire in the sword-making hall has never been extinguished. Until that day, the leader of the Blood God Sect came to the mountain gate with magic weapons refined by millions of souls, and even though they had gone through great cultivation in the Taoist Realm, they were still retreating steadily. I couldn't hold it back, so I picked up the hammer I had been using for ten years and walked out of the sword-making hall. Then he smashed the magic weapon with a hammer. The sect leader and all the elders were dumbfounded. The Blood God Sect was dumbfounded. The entire world of immortality was dumbfounded. "Common clerk of the Logistics Department, Chen Xuan. Is this what you cultivators are capable of?"
