Cao Xing pushed open the castle gates, and a vast expanse of white immediately filled his vision.
It was as if the entire territory had been shrouded in dense fog.
He could only vaguely make out the black Energy Tower nearby and the other buildings within the territory.
Even the towering Pale Tree flickered in and out of sight through the mist.
After observing the surroundings, Cao Xing thought to himself, Although the fog is thick even during the day, with the Lighthouse's help, we can barely see the terrain well enough to work.
And this Mist Disaster looks like it will last for some time. I might as well use this period to develop the territory and upgrade those buildings.
Cao Xing prepared to summon all the workers.
Before that, however, he opened the Dragon Shop and exchanged 400,000 Ice Dragon Marks for a blueprint.
Exchange successful: You obtained 1 Expert Frost Wall Blueprint. Ice Dragon Mark -400000...
Before the system update, this had also been the highest-tier wall blueprint survivors could exchange for.
At present, most territories only had Basic or Intermediate walls, while Advanced Walls were quite rare.
Yet Cao Xing had not only upgraded the walls around his entire territory to Advanced grade, but had now begun upgrading them toward Expert Tier.
One could imagine just how far ahead he was.
He looked over the blueprint's attributes.
