Seeing the power of the Sky-Devouring Urn, some self-cultivators were immediately frightened and cried out loud. They were scared that their blood would get sucked up and that they would become mummified.
Qingfeng Li was shocked as he stood at the back and saw the four kings of the supreme empires all take out monarch level spiritual treasures. He was horrified because he could clearly feel how powerful these monarch level spiritual treasures were.
Qingfeng Li was certain that if he went up at this moment, he would be killed by these people.
Mengyao Xu also panicked and said in a low voice, "Big Brother Li, these people are way too strong."
Qingfeng Li nodded and said, "They're the existences at the top of the whole Crimson Fire Continent and they are extremely powerful. We will cultivate to that level one day as well."
