As for Grand Master Xuandu's other appearance...
That naturally revealed itself when he engaged with the experiment in [Enforced Rule and Order].
In an instant.
Grand Master Xuandu had originally looked like a gentle middle-aged man.
His long hair flowed freely, tied in a Daoist knot.
It was jet-black and quite distinctive.
At a glance, he looked like a middle-aged man weathered by the years.
A handsome older man, at that.
But because he needed to suppress the transformation of the world rules...
And needed incomparably powerful reason and computational ability...
Grand Master Xuandu instantly seemed to undergo a transformation.
His hair began turning white at the roots, and the change quickly spread through the long locks that reached his waist.
His ink-black hair turned white in an instant.
It was as though the finest ancient ink in the world had been dyed a crystalline white.
It was not the pallid color that immediately made people think of illness.
Rather, it was a white.
Just a white.
Utterly pure.
So pure that it almost seemed to let people feel...
Feel that it existed solely to be white.
There was a sense that nothing else could possibly be done with it.
At the same time...
Grand Master Xuandu, who had looked like a handsome, kindly middle-aged man, also changed.
His face remained the same.
But his bearing gave the impression that his entire face had become devoid of human feeling.
Not that he was particularly unapproachable.
To be precise, although Grand Master Xuandu's current appearance was no different on the surface from before...
Even his microexpressions had not changed in the slightest.
His very bearing, however, had undergone a heaven-and-earth transformation.
An ordinary person's bearing...
If it manifested outwardly through certain microexpressions reflecting fatigue...
Would show through every trace of skin
