Yan Fei had calculated that once this land was created, its total area would reach an unprecedented three thousand square kilometers, which was more than 15 times the size of Dream Island. With so much land, it would alleviate the land dilemma faced by Dream Island. And to create this land, the total amount of engineering would be astronomical. Apart from Yan Fei utilizing the new function of the Drone General Space for the great migration of yellow sand, no one could complete this work alone.
Even if Yan Fei kept up the reclamation work every day without a break, using his previous methods, by the time he had enclosed the total length of the 300-kilometer Yellow Sand Dam, a whole half a month had passed.
