"'recommendations'? What do you mean by that?" Kong Weijun asked as he looked at Su Yu. His eyes are filled with puzzlement. It is just natural for him to not know what are recommendations since he is not from this world, not to mention that he was not exposed to human technology, especially the internet.
"Well – " Su Yu muttered as he organized his words to explain it to them. But, before he could, Duan Yuan spoke.
"Recommendations are something that a person or group of people like and wanted to share to another person or group of people for them to try or experience it." Duan Yuan explained. "Just like spells that we discovered before and wanted to share them with each other." he told Kong Weijun and Yue Qinghan.
"So that's it!" Kong Weijun exclaimed and nodded in understanding. He recalled that he once discovered a spell and told it to Su Yu, then asked Su Yu to try the effectiveness of the spell together.
