An ancient poem says:
Yuezhi has a golden bell that spits fire and hides the truth.
The path of wonderful lotus blossoms is guarded by precious halberds.
The yellow sand is shaken with one shake, and the stars change with the second ring.
Three tones and four tunes lead to the drums. The fresh air spreads across the horizon, and the water in the Dragon Scale Pond steams to dryness.
Five bombs and six devastated the Canghe River, fire flags and clouds covered the hand, and the Han barrier and the Qin city collapsed and fled. The ghosts in the Yin Tomb and the secluded capital are in chaos, and the temples in the Brahma Palace are as silent as cicadas.
A sword that can be pecked seven times will not break, and a sword that is melted by real fire will never break.
It hangs high in the sky for nine days, and hundreds of caves collapse under the ten peaks.

Please ignore them all ORZ
The time should take place about a year and a half after the Dragon King of the Divine Capital.
