Water condenses into ice, and although the sea water still exists, it has become ice. In this way, after the sea freezes, it becomes waterless. Yan Yin pondered, "At night, cover the island with salt, and then let the white snake turn into a giant bird to block the moonlight, and the edges and corners of the mountain have been smoothed by us. As long as we are trying to make the sea water become ice, the sky has no sun, the moon has no light, the sea has no water, the earth has no soil, and the mountain has no edges, it will be completed," Looking at the sky, it is almost dusk. Looking at Xia Hanqing, Yan Yin immediately ordered, "Uncle Hanqing, please freeze the sea surface, I will sprinkle salt to cover the island immediately," There is nothing difficult in the world, I am afraid that there are people who are interested. As long as I think about it carefully, you will find that the method is waiting for you to pick it up.
