*reader's discretion alert : content gore and disturbing scenes.
Sky and others continue their journey as soon as the sun rises. They reached the elf boy's home in an hour. It's a simple farmhouse make out of wood instead of sweets. In front of the house is a farm of crystal flowers. The boy quickly ran into the house only to found out it's totally empty.
"Sis, I'm home! Where are you?" the boy is looking for his elder sister who was supposed to be in the house a moment ago judging from the overboiled soup on the stove.
"Where is my sister? She will never left the house with the dishes still on the stove." said the boy. Then Sky smell a scent of blood. Notice that something is wrong, he followed the scent that lead them to a small hut behind the house, the door of the hut is locked inside out. Sky kicked open the door, and saw an awful and disturbing scene...
A beautiful elf lady is half lying on the bloody floor while leaning to the wall, her belly bloated into a huge ball, like a pregnant belly, blood can be seen on her lower body and her hands, she stuffed her own mouth with a piece of cloth to prevent herself from screaming out of the agonising pain.
Seeing this scene, some fragments of memories appeared in Sky's mind, causing him to steps back a bit out of shock.
"Is she having a baby?" said Ai in a shocked yet innocent tone.
"No, elf's body is not built for natural breeding..." said Sky in a totally emotionless voice which is a total contrast with his personality.
"Sky - san? What do you mean by that?" Ai ask.
"Minotaur... She was raped by a Minotaur or more accurately used as a breeding sac..." said Sky with a slightly trembling and pale voice.
"What does that mean?" Ai ask Sky with an anxious look.
"It means she will die as a nutrient source for the minotaur calves that grow at a scary speed." said Sky. "What? That's really..."
"Please, please save her! I know you can save her!" said the elf boy while shaking Sky who is in a gazing state. Then Sky closed his eyes for a while before taking a deep breath and give a long sigh. He took out a small case from his backpack, it's a more advanced version of first aid box, inside of it are a surgical knife, stitching tools, disinfectant, and some cotton gauge.
Sky carefully cut open the womb of that elf lady with the surgical knife, he slowly opened up the cut only to see a really gruesome sight, a pair of minotaur fetuses are eating their 'host' from inside, the lady's womb had been badly damaged by those two monsters which are still continue to grow in a speed that a human's eyes can see. Sky carefully cutting off the head of the fetuses with a dagger, killing them when they are still in the 'sleeping state' to prevent any extra damages. He took out the dead fetuses and put them into a sack before cleaned and closed up the wound on the lady.
Then he turned to the boy. "If she survived, it will be a miracle, if she did not make it, I'll avenge her for you." said Sky before picked up the sack and walked out the farmhouse with Ai.
"Where are we going?" Ai ask.
"The nest of minotaur." said Sky.
"How? I remember it's far away from here..." said Ai. Sky looks at Ai for a while, then he cut his right palm with a dagger, blood dripped out from the cut... Then he placed his hand in the air, a huge magic circle appeared.
"Seiryu (Blue Dragon from the Four Celestial Beast), after all these years of sealing, it's time to shine again." said Sky...

Null dimensions, Stevenson college. Chemistry lab, Chris is doing an experiment with Itsuki.
"Ugh ... This smells like a stink bug, these two are really not a good combination." said Chris while covering his nose... And today he wears a bunny eye patch.
"Yes, I really wonder if anyone would use this as a food additive." said Itsuki, also covering his nose.
"Well, we will never know, there are people with 'heavy taste' in this world after all... Huh?" suddenly Chris look outside the window. "What's wrong?" Itsuki asks.
"Hmm... something really bad is happening." said Chris.
"What is it?" Itsuki ask. Suddenly...
"Pop!" a small explosion occurred in the front table, the test tube bursted due to overheating.
"Ah... That's quite bad."
----------------------------------------------------------------------
At the homeland of Minotaur, some young minotaurs are fighting with each other, then they saw a huge blue dragon flies towards their direction... At that moment, they still not yet realise it's the start of a single sided massacre...
Hold on... Massacre again? Hmm...never mind I guess...
---------------------------------------------------------------------------
Ai watched Sky mercilessly killed those young minotaurs with just a single swing of his sword, then they headed to a cave which is supposed to be where all the full grown minotaurs are.
"Those minotaurs aren't like anything you had faced before, they are very strong and extremely dangerous... Especially for a fine lady like you. So, please stay outside here, I don't want anything bad happens to you." said Sky with a rather emotionless tone. Ai nodded. Then Sky entered the cave.
As soon as he entered the cave, the minotaurs noticed the trespasser, they became really cautious and ready to charge at any moment. Sky looks at them with a despising look before pouring out the content in his bloody sack... Yes, the mutilated dead fetus of minotaurs. Without any doubt, the Minotaurs in the cave getting infuriated by the sight and charged toward Sky at once. The Immortal closed his eyes, as if he is praying for the repentant of the destruction he is about to conduct the next moment...
He had make up his mind, despite of having the risk of been repetitive with the previous arc... Uhm... I mean despite having the risk of exposing themselves again with such a big movement even after that Heavenly Realm incident about a week ago.
So in order to avoid any unnecessary aftermath, the Immortal had decided that he will destroy the whole clan leaving no live witnesses to expose them. Yes, very normal, absolutely no problem with that.
