How to polish?

Guiyi saw that Mu Yun didn't understand, and said again: "You should have seen some ordinary people before, making hoes, shovels, etc. After polishing, they would use sandpaper to polish them, making the imperfections on the surface of the shovel and hoe more obvious.

Sleek.”

"This Thunder Seal Spiritual Paper can be understood as that kind of sandpaper. However, sandpaper only polishes the incomplete parts of the hoe and shovel. However, this Thunder Seal Spiritual Paper can polish the external defects of the boundary device, and it can also polish the internal damage of the boundary device.

The pattern of the vessel is restored to perfection."

When Gui Yi said this, Mu Yun understood immediately.

Repair the boundary weapon! A total of eight black papers were scattered on the ground. The warriors of the Wu family did not care about it.

At this time, Mu Yun put away the black papers one by one.

Wu Yangkun had checked it just now and discarded the black paper casually. It was unnecessary.

At this time, Wu Xinyao also saw Mu Yun's strange behavior, walked forward and said with a smile: "What are you doing with these black papers?"

"I just feel it's unusual. Your Wu family doesn't want it, so I'll keep it. What if it's a treasure?"

Wu Xinyao didn't say anything.
