If the Ghost Soul remains in seclusive cultivation for an extended period and shows no signs of breaking through to the Nascent Soul Middle Stage,
it's likely that the Nascent Soul Perfect Cultivator from the Yin Soul Sect wouldn't allow the Ghost Soul to continue his cultivation indefinitely.
Therefore, He Song needs to calculate the timing carefully.
When the time is appropriate, he must have the Ghost Soul emerge from seclusion.
But by that point,
who knows what chaos may have unfolded in the outside world.
This thought flashed across his mind, and after some deliberation, He Song finally decided to inform Meng Guan and Wei Fan of the demonic movements.
However, He Song did not disclose the origin of this information.
Nor did he heavily affirm its authenticity.
He only warned Meng Guan and Wei Fan to remain vigilant, lest the actions of the Northern Demon Taoists place them in a dire plight.
He Song wasn't too worried about Wei Fan.
