The level of the martial arts of life and death is no lower than that of the Reincarnation Martial Way. With Xuanyuan Di's talent and dedication, it still took him almost three hundred years to advance the Reincarnation Martial Way to the early stage of 110%.
From this, it can be estimated that it took him another two hundred years to reach the peak of 100%. One can imagine how arduous and difficult the process was!
Even with the transformation of the four great martial arts, Shi Xiaole would need over a decade to raise his mastery of the martial arts of life and death to the peak of 100%. But unexpectedly, the appearance of the Supreme Pool greatly accelerated this process!
On the other hand, it also reflected Shi Xiaole's talent. If it were anyone else, even with the Supreme Pool, it would be impossible to make such a dramatic advance in just over a month, more exaggerated than riding on a rocket.
