In ancient Bashu, during the old bronze sacrificial rites, the Sky-Piercing Stone was believed to possess mysterious powers. The entire stone was blood-red, and the ancient people of Bashu believed it had formed from the blood of an ancient creature. They thought the bloodstone could communicate between Heaven and Earth and convey messages from the gods, so it was often used as an important ritual object. During ceremonies, priests used the bloodstone for divination, blessings, and exorcisms, praying for favorable weather, abundant harvests, and prosperity for both people and livestock.
Then one day, by a stroke of luck, Zhang Xiaoqi discovered that the Sky-Piercing Stone was more than just a ritual object. It also possessed mysterious powers.
