When Did My Dog ​​Become Invincible?

Zhang Xuan got a system that didn't look very reliable. The daily tasks are to grow vegetables, ****, and clean. As a result, he was shocked to discover... The vegetables he grows are all holy-level elixirs at the very least! The * he raised turned out to be a unicorn demon saint! Any dish he cooks is comparable to a ninth-grade elixir! Zhang Xuan: "No, absolutely impossible, you must have made a mistake!!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
