The Prescription

Gu Chen's hand, which had been moving the chess pieces, briefly paused. He lifted his head to glance at Song Fan, then withdrew his hand, seemingly contemplating his next move.

This subtle gesture grabbed everyone's attention. Qi Shuo and the others had played chess with Gu Chen before and were accustomed to his rapid playstyle, leaving little room for thought. 

Yet, he had now halted in the face of Song Fan. It hinted that Song Fan's chess skills surpassed all of them combined.

However, Gu Chen remained paused for a few seconds before resuming his brisk pace.

The game had been ongoing for a considerable time, and they struggled to keep up with the speed of these two players. Even Qi Shuo found it challenging to grasp the current situation. It appeared that they were evenly matched, making it impossible to predict the ultimate victor.
