"Phew." Ling Yun let out a sigh of relief after he entered the hot spring, and Bai Zhongyi immediately sat behind him to massage his body. "I didn't expect there to be such a place in this cold place, and the heat in this water is also perfect for relieving fatigue after training, but it doesn't have the effect of Yin-Yang Pond."
"Hehe." Bai Zhongyi giggled at that. "Master, even though underground volcanoes naturally formed this hot spring, you cannot compare it to the Yin-Yang Pond. The Yin-Yang Pond is formed by the meeting of the extreme Yin and extreme Yang, and not all planets have both of them, so it is very rare and beneficial. Even if other planets have both, the process is not easy, and its formation takes a very long time."
"I see." Ling Yun nodded in understanding. "Do you know the location of the Yin-Yang Pond in the upper realms?"
