Chen Changsheng knew what his teacher intended to do, so he naturally did not stop him.
Even if he wanted to stop him, he did not have the ability.
Shang Xingzhou grasped the sword.
This sword had a rather simple and unadorned style, perhaps described as old-fashioned. In the storm of swords, it was very unremarkable.
When Chen Changsheng was bringing out the ten thousand swords from the Garden of Zhou's Sword Pool, he also had not noticed this sword.
Later on, when the Orthodoxy had decided to send the swords back to their old sects, the Li Palace had dispatched extremely qualified and experienced priests to manage the registration for these swords. Still, no one could figure out this sword's background, but since this sword was too unremarkable, nobody cared very much.
