Hello, players can find the signature protection of the equipment owner in Wolong City or Wangcheng City, or use the C key to open the icon of a hammer at the foot of the character image, and can also perform signature protection and other operations. The equipment on the left is made of bronze, and the equipment on the right is made of iron ingots. If the player only wants to get a Samsung device, he can use a common signature. If they want to get six stars, they must first put the equipment on Samsung, then sign the Samsung protection, then continue to get six stars, and so on.
