Ideal City is the core of the "New World", a mysterious world composed of "positive energy elements" and "negative energy elements".
There is a "Book of Completeness" in the ideal city. The Book of Completeness controls all things in the universe and is a symbol of knowledge and wisdom.
When the protagonist travels to the new world, the "Negative Energy Legion" breaks into the Ideal City and steals 5 "Quanpin Essences" from the secret room of the Quanpin Academy. Everything in time and space is out of order, and the Ideal City is in danger.
The Wuchang envoys who guarded the Book of Complete Products couldn't bear that Ideal City was swallowed by darkness, so they turned into statues at the cost of their own lives and stationed themselves in the five directions of Ideal City. They activated the life barrier to protect the Book of Complete Products and the people of Ideal City, waiting for the arrival of the savior.
