Li Qing doesn't care whether Ye Qiu uses Spirit Grass for alchemy or Spiritual Medicine for alchemy; his materials are at the Spiritual Medicine level anyway.
Flames rose in the void, burning slowly beneath the cauldron that emitted an icy aura, which suddenly turned scorching, emitting a reddish glow, heated till red-hot.

This is why Li Qing doubts Jin Zhimo's prowess; it's unlikely that Jin Zhimo's alchemist skills surpass those of his teacher, Pill Master Meng.
The perfect-grade elixir refined by Jin Zhimo must have issues, possibly hidden in the cauldron beforehand, which isn't impossible.
