Everyone should have self-awareness and should not act clever.
However, obviously, those who act clever do not consider themselves as such, which is a sign of lacking self-awareness.
Shangguan Yun was clearly a person lacking self-awareness as well.
Ever since acquiring the Dragon Pearls of the Chamu Clan, he has been killing all over the place for years, even his own wife was not spared, all in order to obtain more Dragon Pearls, living in seclusion and studying the means to harness more power from the Dragon Pearls.
In the end, he successfully gained more powerful strength, elevating his abilities gradually from being equal to Meng Baichuan, the Sect Leader of the Poison Sect, to the Heavenly Human 9th Realm, even condensing the Three Flowers.
Behind this rapid and enormous elevation, the Dragon Pearls were indeed indispensable and also encouraged his quest for more Dragon Pearls to break through to the Returning to Truth Realm, yet he overlooked the cultivation of his mind.
