Lu Zhiyu stood in his huge study, facing two rows of bookshelves. The sunlight was streaming in from the outside, falling on a long table that was scattered with drawings. A sphinx beast was resting by the door.
At present, Lu Zhiyu's eyes were fixed on the wall. There were many items on the wall, the most prominent of which was a mural. It looked similar to a Cabala tree, but Lu Zhiyu preferred to call it the model of the world tree.
This model of the world tree presented the rules of the gods in Maria's World. Upon the model of the world tree, 17 round wheels symbolized different rules and powers of the 17 gods.
Every wheel had a groove. Four of the grooves were empty, and the other thirteen grooves were inlaid with divine personalities, indicating that there were 13 gods that were still waiting to ascend their thrones.
