Tian Meng had bestowed four soul skills upon Zhou Sichen's Body Martial Soul through its First Soul Ring. The effects of those four soul skills were roughly similar to what Huo Yuhao had obtained in the original story, though not entirely identical.
The two identical skills were Spiritual Detection and Spiritual Sharing. Zhou Sichen's Body Martial Soul focused on nearly his entire body, so his Spiritual Power was naturally formidable.
The other two skills were not quite pure spiritual interference and soul shock. That was because Zhou Sichen's Body Martial Soul differed somewhat from the Body Sect Master, Du Busi's, own body.
Zhou Sichen's body also included his soul. It was something difficult to explain clearly; on Douluo Continent, there seemed to be no Soul Masters whose Martial Soul was a soul.
Ghost Douluo Guimei of Spirit Hall from ten thousand years ago might have possessed a similar Martial Soul, but it was not the same.
Zhou Sichen's soul power was extremely special. Having become part of his Body Martial Soul, it gave Zhou Sichen control over himself that far surpassed ordinary people.
Thus, after Tian Meng became the First Soul Ring of his Body Martial Soul, the remaining two soul skills underwent some changes.
After all, soul skills were a fusion of a Soul Beast's abilities and the Martial Soul's abilities. It was only natural that they differed from the original story.
After activating Spiritual Detection, Zhou Sichen began engraving the Core Soul Tool Array onto the Exuviae with practiced ease.
Since the Exuviae was already the finest material available, and Zhou Sichen currently had no quality materials to fuse with it, he simply chose not to add anything else.
Otherwise, not only would it fail to improve the Exuviae, it would instead lower its original grade and quality.
