The Frozen Time River.

Shi Lang did not take out his battle suit as soon as he set off to his journey, but he moved with a black cloak around him. His speed was fast, he did not fly but maintained the ground approach. Since he was moving through unfamiliar surroundings, he wanted to avoid catching any eyes of the strangers. 

His speed was not a problem, but the lack of cover made him understand the cruelty of cold weather. The north was frozen land, Shi Lang was circulating his spiritual energy to keep the temperature in check. He knew that the Parent sects have deployed arrays around the cities to regulate temperature for the people to live in but this place was really too cold.
