Just like the Jade Book Tower is a tower, there's not just one Jade Book Tower.
There weren't many, only about seventeen or eighteen back then.
These Jade Book Towers are spread across the East Continent, serving as landmarks while fulfilling their respective functions.
Moreover, they don't all look like towers. Like the half-star disc here, its main body is actually a city.
Not only do they look different, but their functions are also diverse.
The Thousand Mechanism Pavilion's tower is used for exams, while the Jade Book Tower in front of Zhang Ze, just like the half-star disc, is used for battles.
According to it, during the ancient war between east and west, it accompanied the Emperor on his expedition, beating everyone it encountered, invincible in the world.
As for whom it beat, it's almost forgotten.
Even the comrades are nearly forgotten.
Gazing at the half-star disc in front of him, Zhang Ze paused for a moment and asked, "But you're a disc."
