With the foreign Anomaly [Fairy Tale Kingdom] invading, the Anomalies in this city naturally fought back as well. After discovering that something had happened to the two-star scenario Happy Amusement Park, the local Anomalies quickly mobilized manpower just as they had during the king's parade.
—But unfortunately, every being that attempted to enter the Forest and expel the king ended up hanging from the Tall Trees.
"...Tall Trees?"
"That's right, Tall Trees."
Looking at the row of protective trees before him, Bai Zhi nodded solemnly.
"To pass through a defensive line guarded by these trees, you must correctly solve an advanced math problem. Otherwise, you'll be hung up. As products with rule-based properties, these trees cannot be destroyed and can only be dealt with through the corresponding rules."
"This is also one of Fairy Tale Kingdom's creations?"
Listening to Bai Zhi's explanation and looking at the many people hanging from the Tall Trees, Mu Qiansè wore a strange expression.
"What else could it be? Why do you think I ranked [Fairy Tale Kingdom] among the world's four great disasters?"
Turning to look at her, Bai Zhi spoke seriously.
"[Higher Algebra Tree] is a product of [Math Kingdom] within [Fairy Tale Kingdom]. Besides this kind of tree, that kingdom also has [Abstract Algebra Tree], [Linear Algebra Tree], [Real Analysis Tree], [Complex Analysis Tree], [Numerical Analysis Tree], and [Series Tree] covered in Fourier and blooming with Vandermonde flowers. If you're interested, I can take you there sometime. Math Kingdom has already built several cities."
"What cities?"
Mu Qiansè looked at Bai Zhi and asked warily.
"Don't worry, exactly the ones you're thinking of."
Bai Zhi shrugged slightly.
"Under Lagrange's radiance, Ordinary Differential Equation City, Partial Differential Equation City, Mathematical Physics City, and Stochastic Process City have all been established. A Geometry River
