As a Guardian, he had betrayed his own mission for a reason.
The eight Guardians protected their master's Ancient Tomb, not of their own free will, but because they had been mentally controlled by an Imperial Decree.
The so-called Imperial Decree was akin to brainwashing and body-snatching. It forcibly imposed an idea upon its target, making the target carry it out with unwavering loyalty. The Imperial Decree was highly effective, but its content was very limited and could contain only a single simple command.
Brainwashing and body-snatching were like a cuckoo occupying another bird's nest, controlling the other person's will for a long time and turning them into a puppet.

After issuing an Imperial Decree to a target, even if the issuer died, as long as the target had not fulfilled it, they had to continue laboring away until it was done.
