The intense battle with Aridia had given Shane a good measure of his current strength.
By now, Shane could confidently say that he did not fall short of this era's strongest human.
Half a month ago, Shane had been confident that he could match Aridia without unsealing the Holy Sword, but this could only be achieved by using all his normal abilities.
However, had he been in the situation of half a month ago, without using "Extreme Transformation" and the two major magics he possessed, it definitely would not have been possible for him to intensely battle Aridia with a level under sixty.
Now, half a month later, with the Heavenly Destiny Skill acquired through fusion and a level as high as seventy-seven, Shane was able to gain the upper hand in his battle with Aridia.
This was without even using the "Reincarnation Destiny" that could increase his power tenfold, without using magic, and by choosing to directly face all of Aridia's techniques to verify his own strength.
