Straight up along the stone steps, after the "sky ladder" known as "three hundred and sixty steps", the two-day door is in front of you. Entering the two-day door, the peaks are more strange and the scenery is better. Often white clouds float, reach out to take care of; all kinds of strange animals infested, rare birds are noisy. There are boulders in the door, cracks like sword marks, and it is passed down to the real martial sword test place, known as "sword test stone".
