In such a harsh environment, not to mention ordinary soldiers who couldn't stand it, even Spiritual Martial Arts Masters could feel the discomfort.
The Four Great Prison Kings, each of them had a spiritual qi shield.
This spiritual qi shield was formed by extracting the water element from the Heaven and Earth Vital Energy.
Inside the spiritual qi shield, there was no burning qi, like a shield, it could resist the invasion of fire poison.
Yang Fei, however, went against the norm.
Not only did he not invoke the spiritual qi shield, but he completely relaxed the pores all over his body.
Countless fire elements, under the gathering of Phoenix Extreme, flowed along Yang Fei's Seven Meridians and Eight Veins into his body.
These fire elements gathered at Yang Fei's dantian, and after being refined by Phoenix Extreme, formed pure Heaven and Earth Vital Energy, stored in Yang Fei's dantian.
For Yang Fei, the fire elements that reached an extreme density were a great supplement.
