In the vast desert, the view was wide open. Amid the sand dunes lay an oasis, patrolled by heavily armed soldiers around the mud castle of Earth City, with no place to hide. How easy could it be to infiltrate such a place? A frontal assault was even less likely without heavy weapons and sufficient troops, Luo Zheng also worried and couldn't help but look up at the moonlit night. The bright moon above dressed the desert in a veil of silver and in the distance, a few birds were flying.
Seeing the birds, Luo Zheng's face showed shock and then delight. He whispered, "Brothers, look at the birds flying overhead. If those are hummingbirds, they must have spotted us. But looking at the castle ahead, it's quiet; it doesn't seem like they know we're coming."
