An Lang looked at everyone and said. "Alright. Everyone take a good rest first. I'll be right back in an hour." He then turned to a middle-aged man wearing a grey robe beside him. "I'll leave them to you."

The middle-aged man nodded and turned to everyone. "Hello, everyone. My name is An Shan. You can call me Old Shan directly. I don't mind about it." He pointed at a few tents on his right and said. "These tents are preparing for all of you. It's true that we practitioners don't need to sleep, but trust me. You will understand after staying here for a day."

Xiao Lian cupped her fists and said. "Thank you, Senior An." She then led her people to the tents.

Meanwhile, Yun Lintian didn't follow them and approached An Shan. "Old Shan, may I ask how long you have been here?"
