The Emperor commanded after hearing the man...
"I will allow it to bring the Captain of Imperial Knights here for the audience"
Then a man looking like his late 30s came in knight armour with white Cape and knelt and said "Your majesty we have found the base of the cultists and from there we gained information that their leader is going to attack somewhere in the capital for the sacrifice to evil god"
The Emperor and others were deep in thought and then muttered "some place that will be easy to sacrifice hm~" then suddenly a thought came to him and his eyes widened as he shouted
"Captain take all the knights with you to the academy all the kids of various countries, nobles are there, children are easy to deal with and are weak, the cultists has no easier prey for the sacrifice, on top of that the youngest of whiteblood is their if something happened to him the whole Empire will be at it's most dangerous period and millions will die in rage of the Whitebloods"
The captain on hearing that also realized that was a most reasonable explanation but after hearing the name of the whitebloods he didn't stay there for a second and rushed towards the academy with all 110 Imperial knights
Meanwhile at principal's office a person with same face as cultist was standing in front of principal and other teachers he just came to academy and went instantly to the principal but the principal immediately attacked him on sight and now he is immobilized and tied in magical ropes,principal then gathered others and now he is in front of them trying hard to prove something...
"Who are you? Is Sir Joshua already in his class?" The principal asked him in a tone full of rage and annoyance
The man on the other hand was in very panicked state and he shouted "I'm real Joshua he was an cultist who had ambushed me yesterday and locked me up but I was rescued some hours ago by the Imperial Knights some hours ago when they attacked the base of those cultists and now I'm here if you don't believe me see this..." as he shouted he took out a dagger and slashed out some of his blood on a paper with magic circle and paper disappeared in air and on its place a seal came out
The seal was a proof of being an employee of Academy that was unique to the professors and other workers
Everyone was shocked and the principal said "He really is real Joshua then what is the cultist trying to do by disguising himself as Sir Joshua...
Wait Sir Joshua was head teacher of first year S Class that means he is going to attack that class... Move all the professors and all guards the students are in danger"
And with that all peoples made their way to the class, On their way towards the classroom they saw Imperial Knights making their way towards the classroom, this proved their doubt and principal and knights rushed at more speed
Meanwhile in the classroom...
"FIRE THE SPELLS"
And with that on Klaus's command all students fired the spells they put all mana into and an amazing seen was presented all kind of elements came running towards the cultist although the average of damage was around tier 3 spell but after being fired at same time it gave damage of same tier as of tier 5 spell
After spells were fired the cultist didn't have any more energy to defend because the magic technique he used before required huge amounts of stamina and all his mana and he suffered huge damage and knelt on ground blood coming from all parts of the body and thought 'That damned brat if only he wasn't here! It doesn't matter now! I will sacrifice myself and the even mine soul and summon the devil for killing that brat'
As he said a super creepy smile appeared on his face and he shouted
"YOU DAMN BRAT I WILL KILL YOU EVEN IF I HAVE TO SACRIFICE MINE SOUL
SOUL SACRIFICE___SUMMO....."
before he could say anymore a figure came in his view with all kinds of spells being fired he smiled and shouted
"You shouldn't curse at kids as an adult now get ready for the punishment and like hell I will let you go that suspecious ritual again!!"
"THUNDER DRAGON EMPEROR SWORDSMANSHIP TECHNIQUE___9TH FORM WAVE OF THUNDERSTORM"
and at that time all Imperial Knights , principal and professors were present in the class, the door was broken by the Imperial Knights Captain and what they all saw was an image which got printed in the deepest part of their souls...
A third phantom appeared that looked like chinese dragon purple and silver in colour and sparks of thunder were flowing from it's body, the dragon looked absolute ruler of thunder and klaus throwed one sword and gripped one sword and the whole sword was covered in black and blue aura with sparks coming out it and slashed towards the head of cultist and the phantoms of Ice Phoenix, Black Panther, and Thunder Dragon followed the slash of blade and the a clean cut was made with head getting disassembled from body of cultist as it fell in floor his whole body and head starting to decompose, roasted and then frozen in ice
A complete silence in class room and then the phantoms behind klaus disappeared and the sword he was holding turned into pieces and klaus has exhausted all his mana and he felt dizzy lost his balance and fell on his butt and said with sweats all over his face
"That was a good fight! Nice timing classmates! "
After the moment of silence all students in class roared "WOOAAAHHH!!"
"Thank God ! I'm alive !"
"I thought I was going to die today"
"What are Knights and guards doing? How can a cultist enter here in the academy"
"Oh my God but klaus is more amazing he at least used 3 tier 8 swordsmanship and tier 8 spells and on top of that all were self made, he really deserves being called one in trillion genius"
Capitan and principal all sighed relief after finding that childrens were safe and childrens were escorted back to their homes by knights and Captain went and checked the body of cultist ' intermediate tier 4 swordsman, he was able to say it while only being a freshman at age of 12 as expected all peoples from that family are monsters'
The captain and all his knights present their shuddered after seeing the current situation the whole class was destroyed with a mark of sword all over the place and marks of corrosion and ice all over the place
"So this is the fire power of 'Legendary Magic Swordsman'"
Suddenly a young knight said that but it was heard correctly by all and they just showed a face of respect and fear towards Klaus.
