When Wu Mo noticed Cao Jianzhong's confused expression, he immediately waved his hand and explained, "I have something to deal with at the Fifth Research Department. That's why I'm leaving in a hurry.
"Please forgive me for not giving you a heads up."
Seeing Wu Mo's apologetic face, Cao Jianzhong instantly understood that Wu Mo was preparing to go back so soon because Academician Xu had already made arrangements.
"Oh, I see." He nodded and quickly stored the document signed by Elder Huang in his briefcase.
Cao Jianzhong was about to leave with his briefcase, but he stopped after he took two steps. Then, he turned around and spoke to Wu Mo as if something just occurred to him.
"Wu Mo, although you've only been here for two months, you've contributed so much to the armory. I'll remember your help. If you ever need our help in the future, you can definitely count on me," he said with a serious face.
