Chapter 520: Black Gold Dan

Peter Brown didn't care about Sarah's thoughts, and refining a Spirit Awakening Pill was just a casual act for him.

Seeing Sarah's grateful expression, Peter was happy for a moment, but quickly put those feelings aside and returned to his room.

After experiencing today's events, Peter had a feeling that something might happen in this city, and he had to make some preparations.

Sitting cross-legged in the room, Peter thought about it and decided to focus on improving his cultivation. As long as his cultivation level was up, no matter how powerful his enemies were, they couldn't hurt him.

Having adjusted his breath, Peter took out the Lingcao required for refining Black Gold Dan.

A large amount of materials were placed in front of him, and Peter took out the Ruyi Furnace.

For Peter, refining Elixirs was no longer difficult. Although Black Gold Dan was a complicated elixir, it was not too challenging for him.
