His lifespan had been 1,478,852 years after devouring the Crystal City, but he had spent 272 years ago on Divine Metacs to come here and an extra 3,121 to defend against the spying attempt of the seer and the curse of the death cultivator.
So what was left when he arrived was 1,475,459 years of lifespan. Then he consumed the millions of living creatures in the world.
The average amount of lifespan he acquired from devouring the living creatures was one month. In total, he got 8,356,712 years of lifespan.
He also acquired 53,636 units of law fragments from devouring the world. This is why his lifespan and amount of law fragments have increased to 9,832,171 years and 7,189,985 units of law fragments.
All in all, he had received a lot for devouring the small world. But when he thought about how he would have gained 9 million square kilometers and the 53,636 units of law fragments if he had assimilated the small world instead of devouring it, he felt dissatisfied.
