Maribel's understanding came from thousands of years spent among the storms. Noah had lived there for a long time, but he couldn't match the cultivator's expertise in the field.
Noah had tried to inspect the chaotic laws and the weak sky, and he had even found hidden meanings in the former. However, it was nearly impossible to develop an actual method that could make him understand what that energy would generate since Heaven and Earth hid part of their plans.
Formations could help, but Maribel didn't rely on them either. Her ability to understand the environment's purpose came from instincts developed throughout countless years spent living inside Heaven and Earth's world.
Noah's understanding of instincts made him accept that he probably wouldn't be able to reach Maribel's level. He lacked time to develop proper habits, and his connection to the magical beasts' world actually worsened his potential in that field.
