What kind of novel was it about the protagonist being tricked into buying a magic weapon with a weapon spirit?

I just forgot the name. I remember that it was one of Xianxia and Fantasy. Then, the main character was a rookie. He went to the market to buy something and was cheated by a stall owner. He bought a very trashy magic treasure. Who knew that there was an artifact spirit that had lived for more than W years inside. Then, he helped the main character level up. However, the pill formula that he told the main character was from ten thousand years ago. Many herbs had disappeared.

Answer 1

This novel was called "The Master of Scientific Refining". It was a fantasy novel about a foreign continent. The protagonist was tricked into buying a magical treasure that had a weapon spirit inside. Then, he gradually grew up through the use of machines to break the array and alchemy machines. It was different from the traditional immortal cultivation method and was very interesting. I hope you like this fairy's recommendation. Muah ~😗
