Upon hearing this commotion, Dong Guoning turned his head to look. He saw Zhou Zhenghua, an Interpol officer, anxiously hurrying down the stairs.
Upon seeing Dong Guoning, Zhou Zhenghua paused for a moment. Then, remembering Dong Guoning was Zhang Beixing's classmate, he asked, "Classmate, have you seen Zhang Beixing?"
"Zhang Beixing? He just went out." Dong Guoning pointed to the door behind him and then asked Zhou Zhenghua, "What's the matter, Officer Zhou? Are you looking for Lao Zhang for something?"
Upon hearing Dong Guoning's words, Zhou Zhenghua thought to himself, Nonsense! He was coming down in such a hurry to find Zhang Beixing; did it look like nothing was wrong? What Zhang Beixing had done in Ancient Rome yesterday was still fresh in his mind.
