Legend has it that after Dayu controlled the floods, he buried the bones of the surrendered "Dragon of Chaos" in nine states to stabilize the mountains and rivers. Those who collect the "Dragon Bone Secret Box" can restart the ancient dragon veins and have the power to reshape the world.
· Unique setting: "Dragon Bone" is not an ordinary fossil, but a strange substance with biological activity. When it is approached, it will disrupt time and space (produce hallucinations and see historical fragments), and requires special methods to seal it. Tomb robbing is not only a physical adventure, but also a challenge to will and cognition.
