At 870 years old, Levi is still cultivating on the Ancient Dragon Continent.
In recent years, while browsing the War Merit Store, he discovered two very useful and top-grade seven-circle spells, and spent ten million war merits to buy them.
They are "Wildness Sound" and "Shadow Wind."
These two spells come from the School of Spiritualism and the Shadow School of Thought, respectively.
The former is similar to Levi's Music Fungus; it is a sound wave that can stimulate beasts and transcendent creatures, enhancing their combat power. Transcendent creatures within range can receive a temporary boost. If cultivated to the Maximum, their overall strength can be increased by up to one-fifth, with no limit on numbers.
For Levi, who possesses Lopez and the Dragon Palace, this is simply a god-tier aura skill. He soon cultivated it to level 14, and this spell can always be used continuously, effective even on transcendent creatures that surpass Levi's realm.
