Ultimate Clairvoyance.

Summary

Xia Lei found an ancient tomb that resembled the one drawn by Da Vinci. The tombstone had Italian inscriptions and a half-cross, indicating many visitors. Behind the tombstone was a small mound with a broken tombstone and a cross. Xia Lei felt excited, thinking this could be the tomb he was searching for. He used his see-through ability and found a marble slab 1.5 meters underground. He dug and found the slab, but it was too thick to see through. Xia Lei was frustrated, but then he found a white jade ball with a bronze gear and letters. He turned the gear, but nothing happened. He found another gear and turned it, but still nothing. Then, he remembered Da Vinci's "Mona Lisa" and used the letters A and E to unlock the marble slab. The slab opened, revealing a gap, and Xia Lei found a space filled with black bones and stone walls. He recalled Princess Yong Mei's description of a dark world and wondered if Da Vinci had studied such a space. Xia Lei decided to explore the space and used climbing gear to slide down to the bottom.
