300 km Southwest of high heaven city was a mountain range. These mountains were steep and deep, covered by forests, and there were all kinds of birds and beasts in the forests. Even in broad daylight, one could see the clouds lingering in the mountains. Standing at a high place, one could see the waves and clouds flying under the mountains, and the water vapor rising. Occasionally, when the sun shone into some deep valleys, one could even see some darkness in them. Or a rainbow-like poisonous miasma.
