How did you get the signature? The journey is nostalgic.
What you bought is a perfect green suit. You need equipment above level 60 to sign a contract at Wangcheng NPC Equipment Upgrade Office. A perfect signature needs two 5= advanced materials, one 4= low-level materials, and an imperfect one needs two 4= advanced and one low-level 4=, so the cost is much higher than that of the imperfect one. Answer finished; Give it to me.
