The so-called "Supreme Forgetfulness" means to thoroughly abandon the disturbance of emotions, becoming detached and impartial, with reason taken to its extreme.
From a practical standpoint, reducing "occupancy" indeed can improve operational efficiency, especially in higher realms where shielding emotions becomes easier.
Thus, consciousness instinctively gravitates toward "Supreme Forgetfulness," something Lu Li deeply understood.
Now, he had grown much colder, his emotions having not experienced drastic fluctuations for quite some time.
Even if he crushed an entire world, sending billions of living creatures into mourning, his heart would remain undisturbed.
If this had happened when he first began his cultivation, he certainly would not have been so calm.
Supreme Forgetfulness is an inevitability once life reaches a certain level.
