Chen Qianxue did as the Great Wei emperor, Chen Fengyin, said. In a very short period of time, she informed all the Nascent Soul stage experts in the Great Wei Dynasty that she could contact.
The 'Heaven-reaching Mirror' was a very unique spirit tool in the Imperial Palace of the Great Wei Dynasty. Its function was to transmit information remotely.
However...
The prerequisite was that the other party had a very special jade pendant that the Great Wei dynasty had once gifted them.
Only then could they receive the information transmitted by the Heaven-reaching Mirror.
This very special jade pendant had not been produced hundreds of years ago.
That was because there were no more materials to produce this kind of jade pendant. And hundreds of years ago, all these jade pendants had been distributed to the Immortal cultivators of the noble sects in the territory of the Great Wei Dynasty.
