We are talking about the planet blue star where once the fight between demon king karnark and diety fought for the blue star planet 5000 years ago.
Blue star is a planet exists once in a million a planets average spiritual energy is likely to be 4.1(average millenium tons of mana present on planet)but on blue star has 7.6 spiritual energy highest ever recorded.
The fight was going for the same matter
that who will get to rule on blue star the fight lasted over several years.
Blue star was a place where any space alien monster or being can make their habitat if they have atleast a tiny bit of mana.but people of blue star were unaware of this and the fight also which will decide their fate.
But people on blue star were at lost in both situations since both demon king and diety wanted to rule this world .
After several years the fight ended in the favour of demon king and diety got defeated. Diety has roamed through blue star and knew some people of blue star before facing death diety blessed the planet with mana and embedded his power in every one of the planet little-little.
Demon king heart was also pierced his condition was not good that he can pass through the spiritual energy present in atmosphere (only powerful entities can pass through the spiritual energy from outer space on blue star)it was possible if he could fully recover.
But due to his heart pierced the time taken for his recovery was too much.Seven asuras who when combined were equal to demon king cannot wait that long and the strongest among them pierced the heart of demonking and pass it on blue star.
Both the diety and the demonking were dead the remains were the infinite demons of demonking who were led by seven asuras.
The demon king was killed because it was said that the one who kill the demon king inherits its powers the main power that asuras wanted was creating dimensional rift.
The leader after inheriting power created a huge dimensional rift when his monster entered half of them got caught in rift even leader faced backlash.
Then they understand creating that big rift in spiritual energy of 7.6 is not possible because demon king also can't use it for planetary transport.
Leader of asura said that we can only have our foot on planet blue star if it's spiritual energy gets to 10. The other asuras said it's not possible we would have to wait millenium for that asura said no the power of that diety is now inherited by the people now they will use it and gain more mana which will raise their spiritual energy.
We just have to add some fuel in it we will create rifts time to time so that they can grow faster and spiritual energy gets bigger in this planet.one asura pointed what if someone can surpass us that question ends conversation.
5000 years later the boy in middle school named kamish was sleeping in his class and then he heard some of his classmates talking about him that what would this trash awaken.
By that conversation he knew they were talking about academy selection test it was a test designed for students who are qualified to rise with demon.
Kamish was looking outside and he saw a lady wearing dress like nurse and some professional with suits were coming principal greeted them and than they were shown the path to hall we were all called im hall.
And then queued everyone was standing and then miss nurse told us something interesting we all knew about serum but about its history no one told about it.people shared that some people get powers to beat the monster in rift after serum shot but many remains same and live their normal life.
People only shared that much information to the kids although many people's were strong without serum also they say some diety has blessed us.
But that day nurse told us that 5000 years ago we got to knew about some diety then only we started encountering rifts but slowly the monster in rifts have grown but not our powers are growing.
So 10 years ago our famous scientist mr Daniel when researching a ocean he got a body in the middle of ocean you can imagine how a body can there be in ocean when there is no ship nearby when he researched the body he found a perfect body who has surpassed human limit.
But the body has no life the DNA and blood in the body were still regulating but no life he noticed that no virus was causing harm to him after that he experimented on rats and saw that rats greww bigger and they have enormous mana surrounding them.
Then he tested it on himself and his mind boosted his body got reconstruct but his crewmate has not effect then he knew only few chosen one are selected by serum.
After three years he got to know that his surroundings mana is so much that it has generated a body like a demon by mana and his fighting skill has improved so much.
And the most important thing was he can always generate that mana anytime in his surroundings like a demon surrounding him and protecting him after investigation we got to know that there was a demon who talks with mr Daniel and have developed after three years.
Many cases were found like that of human getting power of demon since it was efficient power and no backlash only few people with less mental strength get caught in demonoid and become demon .
And that was the end of speech and at last nurse said thatwe have serum to rupture demon in your mind before three years it comes to your mind.so mostly students who can't bear demon they get some buffs in their stats.
The people with buffed stats can get admission in various academies but people who have demon are bind to central academy at capital so let's start the test said nurse.
A student asked a question how will you know that he has demon after getting serum shot.Nurse politely said that the demon barrier appear first time even if it is not mature and come out after three years but if it is there you will know at first.
All the student quede started praying for their test and the nurse shot serum one by one behind kamish students were talking what this trash will get kamish was a boy with no parents.
Always helped his villager he generally worked in an inn for living he admired the inn masters daughter who took care of him as brother and that's why he was praying to not get the transformation (other name of getting demon).
He wanted to help the inn master to repay their debt and that's why he didn't wanted to go outside but if he got transformation power he has to make decision which will be harsh on him or inn master.
He was thinking this but suddenly a call came from class teacher kamish it's your turn come here.kamish went there with his legs shaking and class teacher send her to the place behind the curtain where some students were deep in sleep and some were outside that side they were send to their home.
Kamish didn't understand anything and sat on table now what will happen with kamish want to know?Read the demon serum
