Bedroom at night

Through the long rants of his history, he first discovers his teacher is a human supremacist and during class, he checks off that this is a fantasy world but when the sitting emperor is named Emmerich Meinhard von Starfall

" F*** F*** this isn't a fantasy world but a f***ing 3rd rate otome game that later turns into an RPG and Steffen Goldwell he the guy who revealed the bastard 3rd prince, mm the 3rd prince".

"wait in the lore of the game Steffen hides the prince's identity for years, educating him until the time is right, then he should be in the most hidden place in the esta..., most hidden"

Flashback- Ethan

'We are here, the most remote annex in the estate'

"Double F*** but the 3rd prince was called Hannes Klaus von Starfall, I guess didn't get his royal name until he was acknowledged as a royal prince"

"If this world follows the plot of the game then I'm destined to be the pawn of the southwest noble faction led by Duke Frederic Lemaitre who wants a weak royal family but without their protection, those psycho princes will assassinate me, a stan to the royal family"

Wolfhard went to sleep with a troubled mind 

The next day Wolfhard was focused on how to survive the plot and as a consequence of his distracted mind, he was reprimanded by all of his teachers for not paying attention.

In his bedroom, he wrote out his plan in Mandarin 

"No matter how I act, I can't see myself surviving in the academy without being a pawn to the Southwest noble faction but I wouldn't be a useful pawn if I'm not recognized as a prince then I only need to worry about the marquis and if I fail it in a public ceremony then also the retaliation of the southwest noble".

"OK plan to fail the bloodline test and do it privately so I only offend the Marquis but he won't find the need to hunt me down to the end of the earth as no one knows of my existence".

 1. Fail blood test privately

 2. Ask the marquis to travel to some dangerous place

 3. Cause an accident there, make Marquis think I've died (He won't spend resources on investigating hopefully)

"Part 1 of the plan how do I fail the test, mm never heard of a blood wizard I know there wizard in the game but never a blood magic human wizard so the test would probably be if I have the royal family power and the 3rd prince in the game did have it but was the weakest user in history".

"In the game lore, the power manifests in royals between the ages of 10-14 so they probably test me when I'm 15, I somehow need to somehow hide my power from who/what test me and plant doubts in the marquis for him to test me privately beforehand in the royal palace".

 1(Updated) control/ suppress power to fail test and plant doubt to the Marquis 

"Now where can I go and 'DIE' that no matter what, it can't be revealed that I'm alive"

After a long deep thought (Wolfhard didn't sleep that night)

"It has to be the sea, they can't investigate what is lost in the sea and it just so happens the least dangerous of the dangerous sea is, the closest to the Marquis's territory".

 2(Updated) Disappear in the Chanted Sea and potentially be strong enough to any shadows if sent

After Wolfhard finished his plan it was the next day and time for his morning training but he wasn't tired, he felt a new sense of energy finally in his new life he had a sense of direction, a plan to control his destiny.

Now in the first part of his plan figures out how to control that power, supposedly the emperor teaches his sons but with his adult mind he should be able to do what a child can. For the next months before his 10-year birthday WolfHard uses his meditation during swordsmanship class to focus on feeling inside his body in the: stomach, heart, the mythical Dantian, and pretty much anything he reads from manhwa fantasy story.
