Xing Ye
Summary
Chi Xing, who was nicknamed, “star of calamity”, would run into all sorts of bad luck every day. But after he met the arrogant, antisocial, Ling Ye, who had deformed legs, he unexpectedly discovered that his suffering physique improved. Whenever he was with Ling Ye, he could turn danger into safety, and Ling Ye’s gaze always made Chi Xing feel like they had met before, a feeling of familiarness. They both don’t know that their common past of suffering and agony would cause them to be tangled up together……
In a system like that there would need to be rigorous documentation and certificates of prior ownership/guardianship or else anyone and everyone would just get grabbed off the street and enslaved at any time, and such a society would collapse instantly. So these slavers wouldn't have such documentation unless it was a forgery since the kids were just kidnapped; both offenses should be very serious capitol crimes. Once again, the day is saved by glorious Bureaucracy! (and the MC's knowledge and exploitation there of).
