MTL - Black Tech Internet Cafe System - v4 Chapter 591 Want to understand the meaning of life, think... is it really alive?

This is the story of a crazy lich who possesses an internal game system and brings catastrophe to the entire world.

Lyle Walt is a young noble boy and heir looking forward to the day he can inherit his family’s territory. Except around when he was 10 year old, his parents started neglecting him more and more in favour of his little sister, Celes.
On his fifteenth birthday, he is challenged to a duel by his sister to see who will inherit the household and horribly loses, being cast out of his family. Afterwards, he gets treated by the family groundskeepers and receives the family heirloom Gem from him that Lyle’s grandfather had entrusted to him. From there, he begins an aimless journey with his childhood friend and former fiancée, Novem, and the Gem-turned-Jewel that houses the memories, personalities, and Skills of seven of his ancestors.

I can see ghosts. Even the ghosts inside games. But then…”Ah! Not there, over that way! My family heirloom is hidden there.” The ghosts in the game keep revealing hidden pieces to me.
