Lu Yu needed stronger opponents.
Only by battling stronger enemies could he deepen his understanding of the Heaven and Earth Law.
The great path of heaven and earth is vast and boundless. Each person's understanding is only a part of it, and one's lifetime is limited. No individual can completely master it.
By grasping and understanding others' insights into the great path of heaven and earth, it equates to having new understandings of the Heaven and Earth Law and thus enhancing one's own comprehension, bringing oneself closer to the great path.
In simpler terms, it means learning from others' strengths to improve one's own weaknesses.
Use others' strengths to compensate for your own shortcomings.
Solely relying on oneself to understand the Heaven and Earth Law could take an immense amount of time. Moreover, people's comprehension varies. Only by learning extensively can one truly understand the essence of the Heaven and Earth Law.
