Hidden Master After a Century in the Sect

Transmigrating into the world of cultivation, Lin Yan awakens the system of long life by lying low. While others fight for inner sect spots, he gives them away; while others risk their lives for ancient secret realms, he blocks the entrance with rocks; while others battle for fame in the arena, he hides in the back mountain planting vegetables and basking in the sun. The entire sect laughs at him as a once-in-a-century waste, a Qi Refining first-layer layabout. No one knows that by relying on the system's 'avoid danger for points, get scolded for levels,' he has silently cultivated a perfect nine-grade foundation, mastered movement techniques, and acquired magical artifacts, with strength surpassing inner sect elders. When a beast tide sweeps the sect, elders bleed and disciples wail, he hides in a cellar eating dry rations. When the wolf king attacks and an inner sect genius is on the verge of death, a green shadow instantly kills the wolf king, leaving no trace. Not until a hundred years later, when the demon army presses in and Qingyun Sect is on the brink of destruction, does that old vegetable farmer forgotten in the corner walk out of the back mountain with a rusty sword. One sword strike changes heaven and earth. The demon lord looks up in shock: 'You... aren't you that Qi Refining first-layer waste?!' Lin Yan wipes his sword: 'Sorry, I was lying low, and accidentally became an ancestor.'
