Nangong Lie was smart and stuffed his nose so that he could bear things better. Qin Feng and Yun Chen were also rather calm. But this was Jing Ze's first experience with this amount of blood and he looked very conflicted.
Mu Ziying was the only one who looked like it was completely normal to be soaking in a pool of demon blood.
The reason Ye Qing had them soak inside the pool of demon blood was because the demons in this Evil Soul Forest were very special. Their blood could nourish one's veins and tendons.
It was several hundred years later after the Evil Soul Forest was completely conquered that people realized this secret.
Although Ye Qingtang had been guiding Lei Yan and the rest and adjusting their cultivation methods, this was a good chance to strengthen their foundations. Especially since they had just endured a highly intense battle and their bodies would be extra receptive to external nourishment.
