Ye Futian didn't look at Wang Yuqing. He kept looking at the individual space.
The martial arts battlefield had no Spiritual Qi. It only had omnipresent martial arts fate. Cultivators who entered the battlefield had their own plane but could only use their Spiritual Qi to fight while stealing martial arts fate from the battlefield. They would use up their Spiritual Qi, but if they stole martial arts fate, they could continue fighting.
These were the rules of the battlefield. Some said that it wasn't real; the field was just a mirage created by an early sage. One couldn't tell real from unreal. Others said that this battlefield truly existed. Everything was real. The sage had just used a special force to turn it into a training ground.
