Ling Feng thought of a word, and that was "Sky-covering"!
He hoped to find a way to cover the sea and sky near this island completely!
Not only cover it, but make it completely dark, not letting even a trace of light in!
Moreover, the coverage must be large enough, because if there is residual energy on the island, it will certainly make a desperate struggle by sending Demon Clan warriors out to cause destruction!
So space must be left for the ships to dock, to prevent the Demon Clan!
He estimated in his heart that creating such a vast space would require a considerable amount of materials.
A single side must be at least ten kilometers long and about ten kilometers high, and to create a curtain that can cover the island, a single side's area alone must reach one hundred square kilometers.
Four sides plus a top layer main cover would require a total of five hundred square kilometers of area.
No tarp manufacturer would have the production capacity for this.
