Laying Low in the Servants' Quarters, I Turned Scrap into Immortal Artifacts with Critical Hits

Chu Xuan is the lowest-ranking servant in the Tai Xuan Sect. He has to endure deductions from his wages by the stewards and live with the danger of being used as cannon fodder.

Then one day, after a senior sister from the Hehuan Peak drained him nearly to death, the Treasure-Gathering Basin his parents left him appeared.

"Put in a low-grade Qi-Gathering Pill, trigger a hundredfold critical bonus, and obtain a top-grade nine-veined immortal pill!"

"Put in an incomplete sword manual, trigger a thousandfold critical bonus, and obtain the Heaven-tier Great Wilderness Sword Art!"

"Put in a blade of grass, trigger a ten-thousandfold critical bonus, and obtain a Nine-Leaf Immortality Elixir!"

Years later, the demons invade and the Immortal Realm collapses. Countless Immortal Emperors despair as they await their deaths.

Chu Xuan walks out carrying his battered basin and casually spills out hundreds of millions of top-grade immortal weapons. "Don't panic! Everyone pick one and hack them to death!"
