Azure Sky Great Wall—this name is, in fact, mostly for Shen Yu's convenience.
The schemes proposed by the Gray Mist, or the names of its techniques, are almost always like this.
In reality, what is being constructed is certainly not a Great Wall.
It is a kind of grand array that encompasses the entire world!
After Cultivator Shen Yu was the first to point this out, all the Earth Immortals present felt an indescribable tremor deep in their hearts.
An array that spans the entire world!
Even within the Cosmos, at the Immortal Sect Headquarters where True Immortals or even greater existences reside, such a feat is utterly impossible.
For an array that can shield a sect headquarters, the cost and time required are already beyond imagination.
The larger the array, the harder it is to forge.
