The Difference Between Immortals and Mortals

In the transit carriage of the train, a black cat with snow-white paws, looking like a plum blossom in the snow, lay on a mat before Zheng Zetian, diligently licking its paws and washing its face.

Accompanying the cat were two Real Person enforcers from the Discipline Institute, their heads covered by iron masks, wearing mountain-patterned armor underneath and black official robes over. They carried Black Sword on their backs. These two true lords stood to the left and right of the cat, their masked eyes fitted with two incredibly polished black lenses that reflected the Mingguang, like two impermanent ghosts guarding the feline.

Beside Zheng Zetian, Lu Qi's two leopard-eared Railway Warden stood guard on either side, flanking the doors to the 'First Class' and 'Economy Class' cabins.

Zheng Zetian looked up at this one, then that one, and finally down at the cat.

This is just a cat, right? What's going on? Are you bringing pets on duty? And you even brought it a mat??

"We are enforcers from the Discipline Institute of Ink Bamboo Mountain. Did you report the case? State your business truthfully."

"Yes, this disciple Zheng Zetian. Yesterday, during the explosion in Lou Guan City, I heard that someone had boarded the train with ill intentions, so I volunteered to stop them..."

Zheng Zetian impassively repeated the same story he told Lu Qi, omitting the details about the severed heads. After he finished, the carriage fell silent. The four Real Person did not look at him; their gazes were all fixed on the cat.

The cat looked at Zheng Zetian, then licked its paw.

Zheng Zetian: "...I'm done speaking."

The cat lowered its head and continued washing its face.

The two enforcer Real Person exchanged glances. "It seems you are telling the truth."

*Wait, wait,
