Perfect world international edition, how to kill the last BOSS Helan autumn snow covered with frost

I've killed that BOOS 50 many times, so I should have a say. Hehe, before frosting, the materials were slowly assembled, and later they were directly disassembled into finished products, which means that the forging furnace you saw at the entrance of FS is useless. The little BOOS in front of FS may explode with green equipment, jewels and yellow necklace rings. I have played FS yellow. The last autumn snow in Helan has the opportunity to drop FS85 green weapons and yellow weapons, and directly drop the finished products. . . Finally, I would like to remind you that FS has a good SS open circuit, which runs every hour at most. I hope it is satisfactory. .
