While Jack was devising a way to grow in strength, Lex had also considered what his own growth would look like. As an immortal he already had a tenet, and it was slowly and steadily growing stronger.
He could already see and understand laws, and manipulate them within reason. He could create formations with the blink of an eye, and could completely rewrite how the world worked according to his whims. Of course, all of this was only true within reason, but when considering that the one the reason is being applied to is Lex, the scale itself became much larger.
That is to say, he was strong, and didn't see any obvious weakness in himself. As such, he wondered what he would gain when he reached the Heavenly Immortal realm. So far, each realm played a fundamental part in his growth, each distinct from the others.
The answer was actually pretty easy. Predictably, there was an order to laws, just as there was an order to energies.
