So he essentially combined the two functions. But in the process, he lost the ability to grant life to disciples. However, it was intentional, as it was a loss he had to make.
The Core Metac didn't have much room for complexity. Since he wanted to add something to it, he had to remove other functions and instructions to make room for the new one.
The second function he added was how to make the Core Metac grow like Heavenly and Earthly Treasures. He chose this because he had more influence over the Core Metac than his disciples.
He wanted to help his disciples grow stronger faster, and there were ways to do this, which basically meant giving his disciples a lot of resources. But that was expensive, and he thought it was inefficient.
Instead of helping his disciples grow, he decided that it was a better use of his time to help his Core Metacs grow. Since he could point out exactly how the Core Metacs would grow, he was all the more for it.
