After discussing many times with team members and the established Intelligent Tank and advisors of the Post-death World, Lu Yuanming felt that this confusion likely originated from the lower and base layers of the Post-death World.
This might be a kind of instinctual warning; since his strength increased, this instinctual warning often appeared, and indeed it had brought him considerable help. Although he didn't know exactly what he was confused about or why there was a sense of unreality, this instinctual perception must have some reason. After thinking it over, perhaps it was because something in the lower and base layers needed his confirmation and exploration.
In the following period, Lu Yuanming frequently visited the lower and base layers of the Post-death World, while the rest of the Ascension Collective were busy strategizing against the middle and upper layers of the Post-death World.
