Zhang Family members supported each other as they rushed down the road, but after only a few steps, Zhang Hai suddenly heard a rustling noise.
This sound, like that of a startled bird, immediately put Zhang Hai on high alert.
"What's wrong?" Zhang Feng asked.
He knew Zhang Hai had keen hearing, although just a Fourth Grade, he had better hearing than an average Fifth Grade.
"I heard some movement, it's a bit familiar, like the Brown-Backed Yaks from before," Zhang Hai said.
Hearing this, Zhang Feng was shocked, "Brown-Backed Yak? Are you sure you heard right? It had run far, it shouldn't return the same way."
Zhang Hai didn't rush to answer and pricked his ears to listen again, but despite several seconds of listening, he couldn't hear the noise again.
He glanced back, all was serene and quiet.
He shook his head, guessing he must have heard wrong.
"Sorry, I guess I'm just too sensitive."
