I'm in the Demon Sect's Scrap Pill Room, and I Can Synthesize Anything!

Ye Feng transmigrated to a fantasy world and became an errand disciple in the alchemy room of the Happy Peak at the demonic sect Heavenly Evil Gate.

Just as Ye Feng was gravely injured by a ninth-grade alchemist from the sect, then treated as a cultivation vessel by a senior sister who practiced the Joyful Cultivation Art, and was about to die...

The supreme treasure, the Heaven and Earth Furnace, awakened.

As long as he had enough spirit stones, he could refine anything under heaven.

"Ding! Consumed the ninth-grade delivered cultivation manual Joyful Union Art, the ninth-grade cultivation manual Qi Refining Art, and 20 low-grade spirit stones. Obtained the eighth-grade cultivation manual Yin-Yang Great Art."

"Ding! Consumed 2 defective pills and 1 low-grade spirit stone. Obtained 1 ordinary low-grade Qi Refining Pill."

"Ding! Consumed 2 inferior sword blanks and 100 low-grade spirit stones. Obtained 1 low-grade flying sword."

With enough spirit stones, anything could be combined.

With the Heaven and Earth Furnace, Ye Feng burned through a vast number of spirit stones, saw his cultivation soar, and attained heaven-defying combat power.
