In the mid-Tang Dynasty, there was widespread concern about the extermination of Buddhism. In the twelfth year of Zhenyuan, Pei Tao, the general of Zhenxi, was ordered to sink the Buddha Bone Incense Burner, the most precious Buddhist treasure, into the "Biquan Pool" of the local Buddhist temple in order to quell the long-lasting Buddhist unrest. Days and nights after the water was poured into the furnace, the expected filthy and rotten odor did not appear. The fish head in the pond returned to the miracle place with the light of Buddha's seal, burning away greedy fishermen. All the dirty water flowed into it and became clear on its own. The lotus altar in the center of the pond supported the gush of green springs, which irrigated thousands of hectares of fertile farmland in Ganlong. The reputation of the blue spring pond spread far and wide. Twenty years later, Pei Yue, the general's daughter, accidentally injured a koi carp with a Buddha's seal on its forehead. This injury triggered a bad omen. After being used as medicine, it can cause illness and disease, but it has a strange effect on the source. The Tubo general regarded this spring as a treasure, and he was able to seek poison for his own possession. After the poisonous mistake was exposed, he robbed the stone shield of the Dharma Hall in order to destroy the continuously gushing pillar lotus platform... As the crisis approached, the four bloody mottos of "Kill Life and Destruction" gradually appeared on the stone shield floating in the water. Will the incense burner Buddhist beads hidden in Xi'an Tangshui be abandoned as promised? How can we bear to see the vast expanse of land desolate every inch?
