Yun Feng studied the formulas. She had already made a lot of high-level three-star potions. The number of Transformation Potions was enough. Perhaps she should try to make a master-level formula? If she could make a master-level potion, it would be a step up for her.
Time continued to pass. Si Wen continued searching for the Spirit Gathering Grass, while Yun Feng focused on studying the master-level formula. The difference between a master-level potion and an advanced three-star potion was like the difference between heaven and earth. The difference between the levels of the potions was quite huge. Her master had already prepared the herbs mentioned in the master-level formula for her. She wasn't afraid that she would squander the amount, but Yun Feng had always been careful. The way she made potions was different from others.
