2317 Eight-Desolate Sword Leaf Tree

The formation grandmaster calculated with all his efforts, after a while, he said with perspiration running down his face: "I need five hundred kilograms of rank eight immortal material, heavy sand, to temporarily cover the shortage of this formation core."

Zhang Ji's heart sank, heavy sand was a specialty product of Western Desert and was not produced in the other four regions. How could he collect such a large amount of heavy sand at this moment?

Just as Zhang Ji was worried, the formation grandmaster let out a breath of air and said: "You can get heavy sand from Heavenly Court's storage, but I need someone to go to spectral heaven and pour at least two hundred and fifty kilograms from top to bottom. At that time, we will cooperate with that person from inside the formation and fill the gap."

"I will go!" Zhang Ji immediately said.
