For Tang Rao, going to war with the Soul Capture Pavilion in the Central Emperor Realm has been a long-prepared move, and he was not about to go and stop it because of Cui Baiyi's plans.
Of course, he probably couldn't stop it even if he wanted to.
Since everyone wants to see the Central Emperor Realm and the Soul Capture Pavilion fight, then let them fight.
As for who stands to benefit in the end, it all comes down to personal capability.
Cui Baiyi...
His strength is formidable, and his intelligence is not low, but sorry, sometimes high intelligence also requires some auxiliary means.
Like advanced technology.
For Tang Rao, this was a major advantage.
The Nine Realms and Seventy-two Domains also have technology, but no technological star has ever been as extreme as Blue Star.
Almost the entire history is a process of technological upgrades.
