At the top of Cangyun Mountain, there is an ancient tree at the end of the narrow treacherous path. The dense branches and leaves cannot stop the slanting sunset. This towering Cangyun Mountain is already located above the sea of clouds. At a glance, except for the ancient Cangyun Pavilion on the top of Cangyun Mountain behind, it is full of vast white clouds. A young man sat on the neat grass, leaning against the ancient tree behind him, looking forward and with a hint of sadness as the hot sunlight in the distance in the sky was gradually swallowed by the sea of clouds. The young man stood up and sighed: When will I return day and night? Return is either my body or my heart. The young man is named Lu Wentao, twenty-three years old. He is the disciple of Cangyun Pavilion, the head of Cangyun Pavilion on the top of Cangyun Mountain. The Cangyun Pavilion, which was originally ranked fourth in the Tianshan Mountain list, has been left in the fourth place since Cangyuanzi, three years ago, Lu Wentao, as a personal disciple, has a mediocre cultivation and gradually declined.
