In the World of Souls, Lucien stopped the many thoughts in his mind and was about to find a room in the projection of the castle to take a rest. He planned to meet Leo later at the place they previously agreed, when this whole thing settled down.
According to Lucien's estimation, this would take three to four days. Leo and he had agreed on meeting each other a week later, so he had plenty of time. He could use this time learning how to control his newly-grown spiritual power.
Lucien felt lucky for not meeting any undead creatures here. The deeper one went, the more dangerous this space was. Lucien was only a middle-rank mage right now, and he knew his own limit.
When Lucien was going to step on the stairs, the castle started shaking fiercely, like a boat in the ocean meeting a great storm.
Then, the castle was torn into countless pieces of shadow. A second later, the shadow all disappeared.
