Liu Yao looked at Lu Sheng and gave him a solemn reminder.
Lu Sheng nodded. He understood Liu Yao's reminder well. After all, stellar-level martial arts were the result of a Martial Artist's own Martial Arts Insights. One had to combine it with their comprehended Domain of Mental Realm to fully exert their strength.
Moreover, the realms of comprehension discovered by Liu Yao and Gumo, based on the six Basic Planetary Martial Arts, were vastly different from his own.
Of course, there were also some Martial Artists who could comprehend the Life and Death Realm and the Five Elements Realm, yet even if they were the same realms of comprehension, each person's insights were different, making the roles of their domains differ as well.
This led to the fact that everyone's stellar-level martial arts would be inevitably unique!
You could borrow insights from predecessors for reference and absorption, but to walk the path another person has walked… was simply not feasible.
