My Synthesizer Has Talent

Su Qing was reborn in a poor little village and got a synthesizer right from the start.

At first, he was so down on his luck that he had no idea how powerful it was.

Then he discovered it could synthesize physiques, higher-quality cultivation techniques, and more perfect pills, with a synthesis mechanic that could stack endlessly.

That was when he realized that, in this world of immortal cultivation, his golden finger was his greatest advantage!

You could call it a free-spirited xianxia world, or perhaps an xianxia take on practical research into immortal cultivation?
