Son soon started teaching Sol about the rules of chess.
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 skills started to improve by quite a lot.
Son was a bit shocked by his rate of progress, but he didn't show it.
Soon 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.
The sun slowly set 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 over them and illuminated the surroundings in a calming silver glow.
After some time, the two decided to end their game. Sol had improved but he still wasn't able to defeat Son.
