The Heavenly Corpse True Monarch encountered an extremely powerful dead soul during the process, and helplessly had to sacrifice a Yin Corpse to resist it. He lowered his eyes in cultivation and had doubts in the Netherworld Water that this dead soul was deliberately let in by Elder Soul Devourer.
Specially used to weaken his power.
But even if this is just a suspicion, what difference does it make if there is concrete evidence?
Elder Soul Devourer indeed adhered to the Dao oath and did not attack them. Bringing this up now would not earn him any benefits and would only provoke Elder Soul Devourer to target him further.
A Yin Corpse falling into the Netherworld can be considered a significant loss, but if he truly gains something in the inner circle of the ruins this time, he can definitely fully recover this loss.
Perhaps even turning against Elder Soul Devourer might not be impossible!
