For the next few hours, Xinya worked on making potion after potion. He had long finished making the 20 stamina potions Melvin wanted but still kept going. He wanted to raise his skill to a high enough level so that he wouldn't have to waste money on renting another potion lab. With the recipes he had, he could just manage to get it to that point before they stop giving him experience anymore.
Creating potions was like second nature to Xinya, since that was all he did in his previous life. These potions were what he specialized in, so creating them was very easy. Before he knew it, he had made 100 of each potion recipe. The last one allowed him to reach the skill level that would allow him to make potions outside.
