Luo Qiongcang was too embarrassed to look at Chen Xiaobei directly in the eyes.
He had wrongly accused him of working with the enemy and even made it his mission to kill the young man.
Even then, Chen Xiaobei was merciful towards Luo Qiongcang.
The discrepancy between facts that were presented to him and his experience with Chen Xiaobei made him realize how wrong he had been. Before the watchful eyes of his people, the emperor apologized to Chen Xiaobei and admitted his fault even though it was taboo for an emperor to acknowledge his mistake in public.
This showed that Luo Qiongcang now saw Chen Xiaobei in a whole new light!
The people of Saint Duke appeared to be shocked and delighted at all of this.
Shocked because Chen Xiaobei's Three-Star Earth-God grade black saber was beyond whatever the Nine Zones could comprehend!
Delighted, because Chen Xiaobei was not the Tenshou spy they thought he was!
