Si Ning was planning to turn just to memorize where his pieces were on the board but after seeing Jiang ChenMu he was so shocked he didn't turn back. He only turned to Ah Dai who had an innocent look on his face which made Si Ning wonder that perhaps he sent for Jiang ChenMu instead of Chen An but that couldn't be possible because why would he ever want to discuss his plans with Jiang ChenMu of all people. Jiang ChenMu was the last person Si Ning could ever think of needing in his army, he would think of even Wei first among the many faces he had seen in his army before thinking about Jiang ChenMu.
It was already too late for Si Ning to stop Jiang ChenMu from entering so his visitor for the day was Jiang ChenMu and it was his fault for being engrossed in the board game without lifting his head to see if it was Chen An that came with Ah Dai.
