In case he had created the Divine Metac before, he could easily recreate it with a thought by activating the Divine Metac Creation Ability. It would only cost him some lifespan.
A Rank 6 Divine Metac would cost at least 10,000 years of lifespan. If he was being frugal with his lifespan, he could force a disciple to spend their time and resources refining it.
But if he was trying to create a new Divine Metac from scratch, he could either do the hard work himself or let his Rank 5 disciples with mutated Life Abilities create new Divine Metacs.
One option would definitely cost him time and resources. The other could cost him nothing. So it was easy to see why Dao Lords didn't bother helping Rank 5 cultivators to create new Divine Metacs.
Unfortunately, his situation wasn't so simple. He wasn't trying to make a Divine Metac of his pathway. Instead, he was doing the more difficult work of creating a Divine Metac for an unfamiliar pathway.
