The outside temperature was still dropping relentlessly; however, for ordinary people, it made no difference whether it was minus 30 or minus 80, as long as they didn't go outside.
Standing on the platform outside the refuge center, Dong Tianyu carefully removed his long robe, instantly greeted by a bone-chilling cold. A shudder ran through Dong Tianyu.
But no sooner had this feeling started to manifest than a surge of warmth sprouted from within his body, dispelling the invading cold. After the heat had dispersed the cold within his body, it continued to move along his capillaries, reaching various parts of his skin and firmly holding the cold at bay.
'Looks like the seventh level of Qi cultivation has made me immune to hot and cold.' With a casual punch, Dong Tianyu managed to create a sonic boom - his body had already transcended the limits of ordinary humans.
Months of meditative practice had made the spirit power within Dong Tianyu more substantial.
