In order to protect the spiritual pool from destruction, it has been covered with an array. Only the five countries are allowed to open it. The geniuses from all over the world can enter the array. The blood pool is on one side, and the geniuses from the other side enter separately. The reason for this is that in the blood pool, martial artists must enter naked, and if they wear clothes, their bodies will be instantly contaminated by the blood. This is why the martial artists need to enter separate from the others. Females must not wear clothes or they will die. If that is the case, he says, he will make a fortune. He says that even the fourth-stage mystic level master can enter this array. It is the blood essence liquid, which can transform a martial artist's body. The spirit essence liquid has great value in the martial art world, and is a valuable treasure. He wants to check out the surroundings, but he can't see anyone.
