After thinking about this problem, he said, "A level 8 amplification from law fragments is far more impressive than a level 6 Dao Heart. But the Dao Heart can't be faulted for this. It has simply reached the limit of what my cultivation can allow. Which means that I have to raise my cultivation."
His Dao Heart is not the only stat of his that has stopped growing. There is also his body, soul, mind, and insight. So raising his cultivation will benefit more than just his Dao Heart.
This has made him decide to sign up for a sect mission to earn some divine merit points. The other reason he decided to prioritize raising his cultivation is that the next level of amplification from his law fragments will take too long to accomplish.
