It's not made up.
This segment of history was personally experienced by him, and it was a painful memory that one could not easily forget.
Yongning Palace was the second most auspicious feng shui site in Fengyuan City, after the Imperial Palace.
When he and the Sect Leaders of Penglai and Beiming arrived in Fengyuan, the Imperial Palace had already been destroyed.
Pavilions, terraces, and towers had all collapsed; treasures of gold, silver, and precious stones, as well as antique relics, were scattered everywhere.
The only place suitable for arranging the defensive formation was Yongning Palace.
Yongning Palace was also the last place he stayed before he went into his deep slumber.
Before his slumber, he had asked Rong Shi, the Sect Leader of Great Purity Sect, to freeze his body in ice.
He didn't know whether he would ever wake up, but he believed in always having a contingency plan.
