Martial Dao Rule

After advancing to the realm of Dao Master, a cultivator's essence, energy, spirit, and comprehension would undergo immense improvement and transformation, making it much easier to comprehend other rules.

However, although the difficulty of comprehension had lessened, the difficulty of breaking through bottlenecks and shackles each time would increase considerably. Especially after reaching over ninety percent comprehension and pushing toward a complete rule, the difficulty would reach an unimaginable level.

The reason for this was not only that rules themselves became harder to comprehend the further one progressed. Another important reason was that previously understood rules would affect the comprehension of new rules and could even repel them. The less compatible the rules were, the stronger the force of rejection would be.

For this very reason, whenever Dao Masters chose a new rule to comprehend, they often had to consider compatibility as well. If the compatibility was too poor, let alone comprehending it fully, the rejection during the process of comprehension could even cause problems within their bodies.

Compatibility was extremely important, especially in cultivation at the Dao Master realm.

Even if the compatibility matched, it would often still affect the comprehension of a new rule. Thus, it was not easy for Dao Masters to comprehend more rules. Naturally, the more powerful the rule, the greater the difficulty.

If that were not the case, the many Dao Masters could simply choose those Great Dao Rules to comprehend instead of continuing to select branch rules.

But Song Ankang possessed the Heavenly Book of Fate Defiance, which happened to counter these bottlenecks and shackles. Through the feedback of side effects, it could forcibly break through bottlenecks and shackles. That was why he dared to freely choose these Great Dao Rules without worrying about being stuck at a bottleneck he could not overcome.
