"But in any world, the most precious people will always be those like you, who wholeheartedly dedicate themselves to helping others live better lives."
Professor Zhang smiled at Zhou Huaijin and said, "Who would have thought that our greatest find in Qingshui Village would turn out to be a treasure like Wanwan."
Zhou Huaijin also smiled and nodded. "In a sense, this is a case of sincerity moving mountains."
Feeling a great weight lifted from his shoulders, Professor Zhang relaxed considerably. He suddenly thought of something and asked Chi Wan, "Wanwan, are these devices single-use, or...?"
