Creak.
Amid the subtle noise of the wooden door, Li Chengyi pushed it open and stepped out.
Outside was a pale green sky.
The sky is green!?
Li Chengyi was slightly stunned, but knew this was not the time to be dazed; he quickly stood at the doorway, surveying everything in front of him.
A few meters in front of the wooden hut, there was a wide expanse of copper-colored roofs.
The roofs, large and small, connected to form a vast area similar to a playground--their surfaces marked with clearly defined patterns.
Withered yellow leaves were scattered on top, conveying a sense of cold desolation.
To the left side of the roof, there stood a tall spire.
From its height, one could deduce that the hut was situated directly across from the middle of the tower.
To the right side of the roof was a broad and thick grey wall.
Li Chengyi looked up along the grey wall, and at its much higher point, hundreds of meters up, there was a mountain-shaped ancient Chinese pavilion.
