Although Ghost Physician Fu Wan had gathered a considerable amount of information, he still could not compare with Hu Xiaotian, who had ventured deep into Dragon Spirit Wonderland. Skirting the important details, Hu Xiaotian briefly recounted how he had discovered the Blue Skull there. After listening, Ghost Physician Fu Wan remained silent for a long time.
Hu Xiaotian said, "I think that fireball must have been a spacecraft that accidentally crashed into Qixia Lake. Great Kang soldiers happened to see it fall, so they mustered their forces and dragged it out of the lake. The visitors from beyond the heavens inside believed they were under attack, so they launched their flying craft and fought a fierce battle with the Great Kang commanders. Some escaped during the battle, while others were shot down on the spot. The mural I saw must have depicted one of those craft crashing and the two visitors aboard being captured. After they were executed, their skulls and weapons were secretly stored in the Great Kang Imperial Palace."
Ghost Physician Fu Wan nodded. "Your analysis makes a great deal of sense. It seems you know more about this than I do."
Hu Xiaotian shook his head. "My understanding is very limited. I merely happened to discover that Blue Skull. By the way, what exactly is it used for? Why do so many people value it so highly and fight over it?"
Ghost Physician Fu Wan said, "Those intelligent beings are different from us. They should be able to preserve the information they possess within their bodies through some special method, then pass it on to their descendants. Even after they die, that information can remain in their bodies. Unless their bones are ground to dust and their ashes scattered, the information will endure forever."
