Shen Feng glanced at Lu Wansheng and the others, saying, "You all retreat and wait three meters away."

Lu Wansheng and his companions immediately stepped back more than three meters; naturally, they complied without question to the words of the Carefree Immortal Emperor.

Shen Feng sensed that these people had all stepped back, then his right palm pressed onto the rectangular Life-Locking Stone.

This extreme cold is incomparable to the cold air pervading the atmosphere at present.
