Chapter 234: Refinement Failed

Because Chao Bai had set up a barrier in the room, no one outside could sense what was going on in the room.

However, Kong Rui could clearly sense that ever since the feather burned in the pill furnace, the pill furnace had been emitting a faint buzzing sound.

Kong Rui wasn't sure why this was happening, but she didn't dare to go overboard. She could only continue to focus on refining the two feathers.

However, even after a long time, the two feathers showed no signs of being refined and swayed in the pill furnace.

Kong Rui raised her eyebrows slightly. Then, the hand seals in her hand changed and she increased the activation of her spiritual power.

However, no matter how she changed her hand seals, the two feathers didn't transform.

Around noon, Kong Rui retracted her hand dejectedly.

She waved her hand to maintain the raging flames in the pill furnace, but the fire had already been extinguished.
