Jin Yu and the other seven, each of them carried an imperial weapon in their storage ring, which meant they all carried 8 imperial weapons. They were probably a third of the imperial weapons in the dark heaven.
No matter which sect it was, unless they had very potential emperor candidates, imperial weapons were usually only wielded by ancient gods or their strongest Paragons.
Like Feng Qingxue, although she is an imperial princess, she also does not have any imperial weapons. Of course, that was because her empire only had one heavenly emperor, so they probably only had two or three imperial weapons.
One of them was probably held by Feng Xi while the rest was held by their ancestors.
Even though Feng Xi had the support of several other imperial factions, but it was impossible for them to lend them their imperial weapons. They might lend it to Feng Xi at certain times, but there was no way they would lend it to other members of the holy wind empire.
