Laws were divided into rudimentary level, planetary level. There were even more above the planetary level, such as galactic level, cosmic level, and so on.
What Lin Feng wanted to comprehend was the Law of Tides, which increased combat power greatly.
Of course, it was not that one could only comprehend one Law. It was just that Lin Feng cultivated the Tidal Combat Body, so comprehending the Law of Tides would greatly enhance the Tidal Combat Body.
However, if he comprehended other Laws, it would basically offer no improvement to the Tidal Combat Body. However, Laws could sometimes be used as an aid.
Take the Law of Void, for instance.
If one had spatial talent and comprehended the Law of Void, they could even travel through the universe and construct spatial passages. They would be highly sought after talents in the entire universe.
