Si Ning noticed Shao Lang kept glancing at him but Si Ning didn't turn nor try to make small talk or even say his greetings out of politeness, he knew Shao Lang wasn't going to talk to him since he completely ignored Shao Lang when he was trying to talk to him in the previous court assembly so it won't be odd if Shao Lang thought he was going to be ignored again.
"Xiao NingZi." Xiu TianZhao said when he rushed in to stand next to Si Ning and an announcement of the Emperor arriving was made which saved Si Ning from replying to his greeting.
