Disguise

Hmm...

People of the Mythical Realm truly were very different from outsiders—vastly different.

The biggest difference was that they were filthy!

This filth was not outward grime, but something within.

The bodies of those in the Mythical Realm were filthy, filled with vast amounts of unidentified matter. It severely contaminated the people of the Mythical Realm.

No wonder they coveted outsiders' bodies so desperately.

This contamination even affected the soul; not even immortals could be exempt from it.

Thus, the clean bodies of those from beyond naturally held immense appeal for them, and they wanted to exchange for them.

Aside from problems with their fleshly bodies, the souls of Mythical Realm inhabitants also had problems.

From the moment they were born, their souls remained within those filthy bodies. As a result, their souls became mottled. Though it did not affect their sanity, it did affect their advancement.

The more sullied the soul, the harder cultivation naturally became.

A clean body could not only prevent their souls from continuing to be contaminated, but also gradually strip away the mottling upon their souls. Though it could not remove it completely, it could greatly improve their innate talent.

Given this, one could well imagine how desperately the Mythical Realm craved the flesh and blood of outsiders.

This was a bit troublesome.

Li Su could disguise flesh and blood, souls, and even the other party's source of power—the golden core.

But he could not imitate that particular "filth." It was an aura unique to this world, with an exceedingly strange nature. It permeated everything from within to without, from soul to flesh.

After staying in the immortal mountain for several days, Li Su finally slipped out when people began entering again.

Yet, contrary to his expectations, he found no one from the Hanging Sky
