In fact, regarding how to break through the Innate Realm, after thousands of years, the Yuzhong Guo Family had their own deductions and speculations.
Although they were not clear about the secrets of the martial arts external body, the path of martial arts itself was a process of gradual progression.
With other external sects and foreign nations' Inborn Grandmasters as examples for reference, some conjectures and secrets about the martial arts external body were roughly inferred by the Yuzhong Guo Family.
Thus, according to these inferred goals, the Yuzhong Guo Family began to slowly improve their own inherited Chi Yang Divine Skill three hundred years ago.
One of the results of these improvements was the increasingly closer resemblance of Inner Strength's external manifestation to the martial arts external body.
Moreover, the fruits of these improvements, as well as various other improvement ideas, were naturally inherited by Lu Yuan at this time.
