The Reincarnation King and others in the Netherworld are skilled in the Array Tao, divination and other odd things, so the Rune Imprint on these White Jade Stone Tablets has been handed over to them for research.
Su Xin stayed in the Netherworld for a few days, deeply researching the Sword Canons stolen from the Nine-Layered Sword Pavilion with the many powerhouses of the Netherworld.
In order to fully utilize the power of Sword Twenty-Three, what Su Xin needs is to continuously infuse strong Sword Tao into it.
However, human power has its limits. The Sword Tao scriptures obtained from the outside world are not like those from the System, which naturally have a proficiency of 5%. Su Xin needs to slowly cultivate and comprehend them to reach the peak.
There are quite a few powerhouses in the Netherworld, some of them have insights into Martial Arts that even Su Xin can't match.
Therefore, exchanging and cultivating martial arts with them has greatly helped Su Xin's progress.
