At the Beginning of the Tomb of Wasted Weapons, I Became the Immortal Emperor by Farming.

The resources in the world of immortality are depleted, and everyone is grabbing them. Seize spiritual veins, seize elixirs, seize opportunities. Gu Yan traveled through time and just wanted to farm. While others were robbing them with bloodshed, he buried the waste in the ground. The best elixir with elixir patterns was produced. Another section of the sword was buried. An ancient divine weapon grew out. The entire world of immortality has gone crazy. Until one day, the Emperor of Heaven came to the door in person, pointed at something in the ground and asked, "What kind of skill is this?" Gu Yan held the hoe and said expressionlessly: "You wouldn't believe me even if I told you. I'm just a farmer."
