Wukong was worried that his master had been taken into captivity, so he called the mountain god and the land lord for questioning. It turned out that this place was called "Six Hundred Miles Drilling Mountain". Under the intrusion, most of them escaped without a trace. There are 3 mountain gods left, all mountain gods (1/10), and 5 land gods left, all land gods (1/6). May I ask the original mountain gods, How many land owners are there?
