The Secret Burial Investigation

The age-old mystery my father spent his entire life pursuing is slowly being revealed in my hands. Of all the blank spaces on the sheepskin map, which one marks the legendary secret tomb? What secrets does the long-haired boy with two different-colored eyes and the uncanny ability to see at night conceal? Why is he also searching for the legendary treasure trove of the Heavenly Prodigy? Why are fire lizards, a corpse prison, and an undead ghost child found in an ordinary ancient tomb? What secrets lie at the bottom of Lake Baikal, far away in Russia? Why has the body of a girl my age stopped growing, leaving her with the appearance of a teenager? Is it because of a legendary curse, or is something else at play... Now that I've embarked on this path, I must abide by the rules of the founding master: take the treasure, not the corpse; if the lamp goes out, don't touch the tomb's gold.
