Seeing a lot of focus on how much of a genetic soup a character is or isn't in the notes, but not on what sorts of weird and fun traits their mixed nature gives them. I'll start:
Luo Binghe’s blood can be used as a GPS tracker, torture device, medical intervention, and sex toy. We also know his dad (*Luo Binghe's voice* I dont HAVE a dad >:0) can make animals out of his, but it's unclear if Luo Binghe had inherited that one (though given his protagonist halo, he could probably do that if he tried).
He has extremely robust healing factor. We saw him repair broken bones in seconds, but it's also mentioned he can regrow lost limbs outright. Him having a scar is an important plot point / character beat - because that means he is actively and intentionally preserving it.
Having sex with him can cure severe poisonings.
He can perfectly balance two systems of cultivation, demonic and spiritual. To translate to not-cfandoms ppl, imagine someone who can seamlessly switch between corruption magic and holy magic at any moment!
[ns/fw text in this point] This one is not canon-confirmed, but we're pretty sure he inherited the world's biggest dick (that part is canon btw) from his mom's side, as shes the hugest BDE-haver in all of SVSSS. The woman acted as a sugar daddy to the demon emperor, it had to manifest with her son somehow. [end of ns/fw text]
And of course I have to mention THE design choice of all time, Luo Binghe's mark of sin... also known as 'charge indicator light' and 'built-in kissies target'. This red mark on his forehead:
(eng.edition, thai edition, and vietnamese edition designs)
(donghua design, as present in the opening scene illustrations and Binghe's nendoroid figure. when oh when will season 2 return from the abyss...)
This 'mark of sin' was given to Luo Binghe's fallen god ancestor by Heavens, and functions as a bloodline curse. No matter how many generations it has been, the descendants of heavenly demon bloodline are all branded as beloathed and rejected by Heavens.
Luo Binghe's husband once compares it to a charge indicator light, as when Luo Binghe is injured and unconscious and needs to regain his strength and heal to wake up, the mark pulses with light.
There's at least one instance in canon where it's described to expand to the rest of Binghe's face, and even down his chest and arms. Hot 😳💦
There's a scene where Binghe's not-yet-husband gives his mark a lil kissy ahem uses a totally reasonable method to hide the light of the mark while Binghe is injured and they are hiding from the monsters that react to light.
(as illustrated in eng.edition because @/velinxi fed us SO well)
In fact, when asked his favorite spot to be kissed, the first one Luo Binghe names is 'forehead' (src: ch31, aka 100 questions extra). Baby boy suffered a lot thinking his heritage made him unlovable, okay 🥺
And while technically not canon, in eng. edition wedding art his husband-to-be has A MATCHING MARK PAINTED WAH 😭
(binghe is cryin a lil bit in this one and ngl so did i when i noticed it)
