I Can't Afford to Offend This Outside Handyman.

Everyone in the sect thought Su Jingchen was a useless handyman who got in with money. He had been sweeping fallen leaves for three years, and even though the sword manual was rotten, no one looked at it. Until that day when he casually commented on the principles of swordsmanship, Elder Chuan Gong knelt down on the spot and called him a swordsman with a trembling voice. Three hundred years ago, he was the Wuchen Sword Immortal who broke his own cultivation to seal the Demonic Abyss. In this life, he just wants to hide his edge and live his life with his head down. But the thing behind Moyuan Gate woke up. Gu Changge, his junior brother who locked the door for him back then, has been trapped behind the door for three hundred years. Now the gray hand protruding from the crack in the door is about to tear the entire sect apart. ... During the battle in the Demonic Abyss, the hand behind the door forced him to ascend to the realm and reveal his true identity, but he refused. Qi Zhen was stunned and forced the senior brother out of the door. With the last sword, he drew his sword in public, and the Wuchen sword swept across thousands of miles. Three hundred years of anonymity ended here. The junior brother pushed open the door and walked out. The first thing he said when he opened his eyes was to call him senior brother. In Guichen's residence, none of the people under his protection were missing. He even left a glimmer of hope for the hand behind the door. This novel and its characters are purely fictitious.
