Di Fuyi felt a gentle warmth in his body the entire time he was with Gu Xijiu. It felt just like a breeze in the spring. Everything was going well for him. Even the wound he suffered before from extracting blood directly from the heart was now healed. No scars were left from the injury.
In stark contrast, the wind in the passage was freezing cold. As Di Fuyi stayed in front, he shielded the wind from Gu Xijiu but understood why there were no traps along the pathway. This wind itself would have been able to keep away a significant number of people! The reasons why Di Fuyi could stand the cold were due to his unique physique and high spiritual power relative to the other people in the Shura World.
In order to ensure that Gu Xijiu was really protected, he had even placed a wizardry barrier over her body that could diminish the effects of the wind.
