The Secret

Rowan starts running away when he hears the word demon from John. John observes the fight from a safe distance and hears their conversation. He identifies that one of them is the headmaster of AWMS, Professor Michael, and the other one is a Fire demon named Groth. Professor Michael was an expert in Wind Magic, and his magical weapon is a spear, whereas the fire demon's weapon is a hammer. They fight each other so violently that a quarter of the Public Library gets damaged. Growth uses his hammer to cast fire spells and tries to damage Professor Michael with it, but Michael manages to dodge it and tries to take down Groth, and both of them get ready to give their final blow.
 Groth chants a magical spell and throws his hammer towards Michael, and Michael also chants a magical spell and throws his spear towards Groth. A huge explosion takes place, and both of them get heavily injured, but Michael manages to throw a magical artifact named Heaven Capturing Chain towards Groth and catches him. Groth tries to escape, but his actions are in vain. He tries to send a spiritual message but is destroyed by Michael's spiritual attack on Groth's brain. He asks for the reason he came to AWMS, but Groth refuses to tell, and tries to repent. Michael gives Groth a last warning to tell the reason that he is hiding.
Groth says, "Oh, you wanna know what I am hiding from you hahahaha, you would never know what it is, even my Lord doesn't know the secret I have known recently and searched for, but I can assure that the secret would never belong to you magic users, Muhahahahaha". As Michael has no other way to know the secret, he does a spiritual fight, which takes place in the mind of Groth. John observes it and takes a potion bottle from his pocket, and throws it towards Michael, which affects his spiritual power, and he falls unconscious. Even Groth's spiritual power gets disturbed, and his spiritual power diminishes, and he forgets everything, and falls unconscious.
 All the people in the Public Magic Library get injured and try to move out of the library. John searches for Rowan and sees him heavily injured. He immediately takes Rowan in his arms and summons Roxx to take them to their house. After reaching his house, John rushes to his Potion room and takes a potion named "Rufflegrut" and pours it into the places where Rowan was hurt. Rowan's wounds vanished after a few minutes. Rowan is shocked after seeing it and falls into a deep sleep, as he needs to rest.
 John again rushes to the Public Magic Library using Roxx and searches the belongings of Michael when no one is around, checks them, stores some of them with him, throws some other belongings in some places of the library, and then searches Groth's belongings and finds something unusual,  it's a message from Groth's Lord to prepare for the search of Fire Gem. John also took his storage bag and threw Groth in his chariot. He also searches and finds "The Bloodline" book and returns to his house.
While sleeping, Rowan dreams of getting a voice from an unknown person saying that "You have begun your journey, so follow the good and righteous path and avoid and win over the evil, you will always have my blessings," and when he woke up, he sees the time, it's 4 am. Rowan yawns and gets up from the bed, brushes his teeth, and bathes. He searches for John but finds him sleeping near some books. He wakes him up, and John gets scared and targets his wand at Rowan and realizes it's Rowan, and hides the books near him and packs some books, potions, and magical artifacts. John freshens up and throws some bags towards Rowan and tells him to hold them.
Rowan says, "Where are we going early in the morning ?". John replies, "We are going for an adventure to learn about this world and also to get you some coaching for your exams. John realises that he forgot something and remembers that he should fuse some of his blood with Rowan. John starts chanting some spells and takes some of his blood, and uses the blood fusion technique and fuse some of his blood with Rowan's blood. Rowan felt extreme pain; it was like his blood was burning so hot, and he fell unconscious. John says, "Does everyone fall unconscious for every spell and potion I use, or what?".
John then keeps Rowan in a tub of lukewarm water, and he adds some medicinal plants and some potions. This replenishes the power of Rowan after 2-3 hours, and he gets embarrassed when he finds that he is naked in the tub of lukewarm water. Rowan screams at  John, "What did you do to me? Why the hell am I naked?". John funnily replies to Rowan, saying that "Don't worry, you can trust me, I am a true gentleman". Rowan gets angry to sarcastic reply of John and throws the things near him and rushes to another room wearing a towel. John whispers to himself, "Bro thinks that he is a beautiful lady," and laughs out loud.
John and Rowan get ready for the process, and John makes the magical bond letter, but Rowan snatches it and reads every corner of the letter. John tells Rowan, "Do you still don't believe in me, kid?". Rowan replies to John, "My father used to tell me never to trust anyone, and read every part of the agreement before you sign your signature". John tells Rowan," But you ain't gonna sign, you dumb kid, you just have to pour a drop of your blood for the agreement". Then both of them poured a drop of blood, and the agreement was done; a bright ray of the sun fell towards them.
Rowan asks John if it was a divine sign after the agreement.  John hits Rowan's head and says It's morning, you dumb kid, even the sun rose. Rowan yells at John not to call him a dumb kid again. We are too late. John whispers to himself, "This guy asks more doubts, which brings a headache to me, I may die when he starts asking educational doubts". John calls Roxx, and then they begin to travel. A book from a long distance starts flying towards the direction of Roxx.
THE MODERN WORLD:
Henry, along with his parents and some of Rowan's close relatives, even Richard, arrive at the Police Station. They report asking a police officer to file an FIR. The police officer asks which type of case it is, and they reply that it is a missing case. The police officer asks about the missing people. They reply that Rowan and their parents have been missing for five days. The police officer asks for their full names and hears the Last name "Clark". The police officer gets tense and calls a guy. Don't worry, we will clear the case soon because this case will also be led by our top detective, "Agent Gauss".He is known for his wits and smartness while solving cases. 
Mumbai, India:

Agent Gauss stepped into the grand old house. The thief had stolen only one item: a priceless ruby necklace. No broken locks, no signs of forced entry. He examined the glass case, wiped clean. Odd. Even the base was dust-free. Yet, everything else in the house had a thin coat of dust."Only someone who knew the cleaning schedule would think to wipe it down," Gauss mused. He gathered the household: the butler, the maid, and the gardener."Where were you during the blackout at 8 PM?" he asked. The maid replied, "Polishing silverware."The gardener said, "In the shed, fixing tools."The butler said, "In my quarters. I never left."

Gauss nodded. "Strange," he said. "Only your shoes show no dust, while the others do. And yet, the glass case is spotless."The butler paled. Gauss smiled. "The necklace wasn’t stolen during the blackout. It was stolen during the cleaning by someone who knew exactly when the dust would be gone and returned to cover their tracks." he lifted the rug under the butler’s chair, revealing a faint red glint."Bingo," he whispered.

Meanwhile, Gauss's phone vibrates, and he lifts the call and talks to the police officer. The police officer informs that it's another missing case, and the last name of the family is Clark. Gauss gets alerted as he hears the word Clark from the police officer's voice. Gauss tells the police officer that he will give full support during the investigation and will arrive at the police station soon.
