The four unusual treasures in the jade pool are:
A slim, dark yellow incense stick rooted in a cloud of black smoke at the bottom of the pool. The smoke coiled around it, appearing as if it was ejecting a platform made of smoke. On top of the platform, one could faintly see a statue of Buddha seated cross-legged, a faint smile playing on its lips as it held a delicate flower.
A piece of shapeless black mud, slowly absorbing the black smoke underneath it. From time to time, vague resentful faces would emerge from the mud before silently dissipating into the jade pool.
A small, exquisitely made seal painted with Buddhist symbols like the vajra, prayer beads, wooden fish, and sutra banners on its four sides. Shimmering golden rays of light emanated from underneath it, suppressing the black smoke below.
A small, jade-green sword. Its body was crystal clear, radiating a vibrant vitality, swimming freely in the jade pool like a fish.
