Fancul.

Ryuke returns to the Red Hall after several minutes and bows to the Emperor. "The Imperial Alchemists have arrived, Jeonha. They are waiting in the nursery. Physician Huo is ready and the Imperial Nannies have been warned." The eunuch approaches Bang-sul, who takes a step back tightens his grip on the baby, as if fearing Ryuke would take him off his arms and run away.
"Your Grace..." The Sangseon glances at the Emperor, actually clueless on how to act.
LianBi approaches Bang-sul from behind. "Let the Sangseon take him", he murmurs to the lover, wrapping his arms around his waist. "He will be safe."
With as much hesitation as if he expected the babe to vanish as soon as they lost contact, Bang-sul eventually let's Ryuke take the child, whom bursts in tears almost instantly.
"Gamsahamnida, Your Grace", says the eunuch respectfully, although there is nothing he needs to thank for.
Bang-sul follows Ryuke with his gaze as he walks out of the throne hall, looking terribly troubled.
"They will make sure he is in good health and take care of him, in addition to making sure if the baby is Tero.indeed", says LianBi to reassure him.
"And if it's him...? What will be of him then...?"
LianBi moves in front of him, standing very close, and puts his hands on his shoulders. "Why do you ask me with such trembling tone? Is it that you have something in mind?" And are scared to tell me? - he adds in his thoughts.
"If I..." His voice keeps being shaken but mainly due to all the agitation and nervousness... and yes, also a bit because he fears a negative answer from him. "If I... maybe I... should... raise him this time..."

Before the Emperor could answer to that, Ryuke runs inside with the Alchemist who took care of checking the possible family bounds of the baby. The man kneels and prostrates himself, looking totally terrified.
LianBi doesn't understand why such reactions from them, considering what the task was, bit still gets somewhat worried. "What is it that you found, to cause so much distress? Speak clearly and directly." He has no nerves for blabbing around the thing. He is annoyed already, to be prepared.
"J-Jeonha..." stutters the alchemist, with a really shaken tone. "I have repeated the tests 10 times and even the two other alchemists with m..."
"SAY IT, I ORDERED!" thunders the Emperor, interrupting him.
The Man jumps. "T-the blood of the baby is connected to Concubine Yi, with whom shares an extremely close familiar bond, that wasn't possible to determine with exactitude, though..." He shuts his eyes before to proceed. "And it is connected to Jeonha, with whom he shares a fatherly bond." Not mentioning anything about the fact the blood was pink and absurd. "He is a Sacred Blood with a dangerously 71% level..."
LianBi gets totally stunned by what he says. "What...?!" he hisses in disbelief. "What are you saying...?"
"I swear Jeonha, there can't be a mistake!" implores the man.
The Emperor recoils, getting 175 infarcts at the same time. "Check him", he gasps, pointing at Bang-sul. "HAVE HIS BLOOD CHECKED IMMEDIATELY!" Well, if Tero is the twin of Bang-sul and the alchemist just said he is the father of Tero... he almost faints at the very thought of that. Also since the original Tero, for the age he had when he killed himself, could perfectly match as son of his, he was the same age of XinLi.
All the three rather petrified by LianBi's apparent fury, Ryuke takes the lead and pulls both Bang-sul and the alchemist out of the Red Hall to obey the order of the Emperor.

Bang-sul too is left totally speechless, but the Emperor's anger always scares him more than anything else thus he has little space in his mind to evaluate the possibility LianBi could, in some twisted way, his actual biological father.
Again, several alchemists test his weird blood over and over again to confirm a sure result.
This time it's Ryuke and Bang-sul alone to return to the throne hall, to refer what they discovered.
"The Imperial Alchemists made sure of the truthfulness of their result and stated that there is absolutely no blood connection between Jeonha and Concubine Yi", says Ryuke, trying to be as reassuring as possible.
LianBi approaches them, still out of himself. "Then how is it possible? How would that baby be my son and his relative at the same time? How can he not be Tero? How could a baby survive the magic fire and what was of his ashes?!"
Bang-sul even cowers a little to that.
The Emperor hits his hand against the wall. "Don't be like that! I want an answer!"

Suddenly, the light of the room start to falter, then all the candles and lamp turn off. An unnatural cold pervades the place, and something like the shadow of a BIG little girl appears between them, accompanied by a disembodiment chuckle.
"It's my gift for him", says the voice, echoing in a blood-freezing way.
"Who are you? How dare you being here?" growls Ryuke immediately.
The shadow moves her head towards the eunuch and two sparky pink eyes appear in the blackness. "I am Phoei."
Everyone gasp to that reply.
"Why would... the Goddess of Fear make that child the son of the Emperor?" asks again Ryuke, the less shocked one in the room.
"Because auriold obsess so much over meaningless blood. He feared so much his Bang-sul wouldn't take him, that I felt like to make sure", she explains while moving her head on LianBi. Naturally, her conversation with Tero happened after his death. "Do as you deem right." The shadow of the Goddess slowly disperses, vanishing in the nothingness and leaving only some pink 'burning' marks on the floor where she was standing. Gods can't be in Nortrig for a reason, and that's the risk of causing serious damages to the world, due to their potence.

The three wake up several hours later, Ryuke in the nursery and the Emperor and Bang-sul in the Emperor's residence. They don't need to wonder if what they witnessed was a dream, they all know for sure it was real.
