"We're willing to go!" the three said almost in unison.
"I knew you wouldn't disappoint me." After a moment of silence, King Yama stroked his beard. "It is very dangerous, but you'll be fine as long as your disguises are good. The Fourth Realm is 99.999 percent similar to the real world. As long as you're careful enough not to lose yourselves, it'll be difficult for the World-Ender to discover any real humans who have snuck in. If he doesn't target you, then you'll be relatively safe."
"But the greatest danger is losing oneself, right?" Xin Huohuo, who had been quiet, suddenly interjected.
'The best disguise is to deceive yourself. Only when you believe the Mirror World is real can you avoid feeling out of place and escape the World-Ender's notice. But if even that last sliver of consciousness in the depths of your mind becomes muddled, then you'll truly drown in that false world, never able to pull yourself out.'
