The two men enter the pool, where the yin-yang aura of the water repels the water from the pool. The water is guarded by a curtain light, and the two men are able to enter through the curtain light. The curtain light is a barrier that keeps the water outside, and they can pass through it easily. The barrier is made of yin yang pearls, which are the essences accumulated over many years in the water. The essences contained in these pearls are much more than ten times the amount of water, and if they are absorbed, they will enable the men to enter the heavenly yuan stage. The demon spirit that is guarding the pool is asleep, and even if it is not awake, it still holds a heavenly yuan barrier.
