What does it matter if they know he's pretending? He has already taken control of the Netherworld Path, and whatever they say is useless.
In the current Netherworld Path, it's all up to Huangpu Yu.
Unless someone has the skills to contend with him, they should be smart about it.
And Huangfu BOSS isn't lightly ill; his body has always had hidden ailments, and it's only through meticulous care over the years that he's been okay.
But this time, once he fell ill, combined with the unresolved knot in his heart, his condition became very severe.
To make matters worse, Huangpu Yu seized his position at this time, causing him great anger and distress.
Huangfu BOSS didn't know how many times he vomited blood, his body severely deteriorated.
Then he became critically ill.
To cure his body, he'd need to rest and recuperate in peace for many years.
Years later, nothing would belong to him anymore.
So suddenly losing everything, one can imagine his state of mind.
