Haiyun Sky Hotel, Yin Yihui directly booked two luxurious rooms. For warriors returning from the borderlands, money was the least of their concerns. Moreover, all hotels offered a half-price discount to warriors coming back from the borderlands.
Ning Cheng taught a set of breathing techniques to Yin Yihui, then returned to his room to immediately begin using a demonic core to restore his Divine Sense.
Two hours later, Ning Cheng still held the demonic core in his hand, though he had drained all of its vitality. His Divine Sense had finally recovered a bit, and he barely managed to focus it on the ring, drawing out the spiritual stones from within. At the same time, Grey Toot was summoned by Ning Cheng as well.
"I'm going to cultivate. You keep watch at the door," Ning Cheng instructed Grey Toot before a large pile of spiritual stones turned into a torrent of spiritual qi that flowed into his body.
