Following the traces deeper, I discovered a secret laboratory that was still in operation. The crazy "doctor" uses living people, combines ancient magic and technology, and conducts taboo experiments in pursuit of "immortality."

And what is the truth behind what the ancient sword "Zhenyue" in Lu Jinghan's hand protects? What purpose does Xie Xunfeng have?
When the glass tanks in the laboratory exploded, immortal "experimental subjects" surged out, and the ultimate door buried deep in the ground loomed. A thrilling adventure about life, memory and inheritance, in the collision of ancient evil forces and modern madness, suddenly begins.
