Son soon started teaching Sol about the rules of chess on how the pieces move.
It didn't take long for Sol to grasp the pieces' movements, but to actually defeat Son in a game, he realized that would be difficult.
Son seemed to be really talented at chess, to the point where Sol would lose without even noticing.
However, as the sun began to slowly set and the two played game after game, Sol started to improve by quite a lot.
Son was quite shocked by his rate of progress, but he didn't show it.
Sol's progress reached a point where Son had to take a few minutes to reply to his moves as opposed to a few glances.
Soon the sun fell and plunge the two into darkness, but they were cultivators so they could clearly see the board. Plus, tonight was a full moon; moonlight poured down on them and illuminated the surroundings in a calming silver glow.
