The Fortress of the Lightning God is a big ship with many facilities of all kinds.
From training rooms, to fun rooms. But, the central and outermost part of the ship is, as the name suggests, a real Fortress.
The number of spiritual cannons of the highest level that they have could shake an entire region if they were used. With very high-level integrated defense mechanisms and a teleportation mechanism inside, plus it can contain other spirit ships within itself.
The last time this ship was used it was in the last great war against the demons, and since then, it has been a respected ship throughout the continent.
Even so, this time, it was traveling calmly at a steady speed, with no signs of going to war.
Simply demonstrating its exalted status.
Meanwhile, Shi Yue explained to Tang Yin and the girls, the place where the battle of the great sects will take place.
