To Lin Mo's knowledge, Taihao is the head of the Pantheon and the one responsible for bringing up the idea of the Divine Convenience Store. All the modern product suggestions came from him, or at least, the concept of them based on what he saw on Earth.
Lihua, on the other hand, was the Goddess of Harmony and Commerce. She set up the Customer Service Hotline and based on what he heard from their conversation, she's also a co-developer of the Divine System Interface integrated with the store. She's quite an expert in developing systems.
Apart from them, there were also Xing Xing and Chuang which they hadn't met yet.
Xing Xing created the beauty products and left her signature on each of them, allowing Xiaoyu to create a bundle using her name as a brand.
Chuang was the head of the Development Division and was responsible for forging the weapons and armor being sold in the store.
