Wen Ziheng and Yu Mingxuan seemed too embarrassed to approach Qiao Ranran, but Zhong Yunkun came straight over. He had to admit that her elixirs worked best. He could refine elixirs himself, but his were nowhere near as good as hers. Even after asking her for advice and improving his results, the gap remained enormous.
