3 Created by the mind

The first thing he would have to decide is what to do with his current parents. They are not in awful shape financially, but living with them after the age of 11 is not an option. What to do since staying at Hogwarts is not an option?

- He was going to disconnect from his family after the first year of Hogwarts. It was sad for them, but it was a necessity for both him and them.

-Needed to escape the ridiculous wizard laws (not being able to cast spells without being an adult and not being spotted for illegal acts)

-He needed a lot of money or galleons. Some of the magic items were blessings.

Decided it was unreasonable to plan with current abilities

-Days followed days, 6 months passed in the blink of an eye-

Henry was working the occlumency with his eyes closed, cross-legged on the bed.

"Computer complete, thank goodness I don't need to know how it works."

There were hundreds of thousands of spheres scattered in his mind, glowing thread connections between them.

In his occlumency practices, he understood these ropes work like transfer ties. At first, his control was not very good, but he was learning fast. The reason the computer took so long was the sun, which was the protection he wanted.

Judging from the remote corners of his mind to the centre, there was a giant black sphere in the centre, memory spheres scattered around.

Henry teleported out of the black sun and checked the paper list in his hand.

1- Core +

2- The isolated zone between the core and layer 2 (white room) +

3- Radioactive zone +

4- Surface layer +

5- Fire layer +

6- Wind layer +

"Now everything is ready, but let's check first," then he was teleported back to the core area.

He was a room with a white circle around it, and in the middle of it stood a huge core, about 2 meters in diameter.

He sat on the core and examine it.

"I designed it as a supercomputer, I made it of Uru metal that I know and does not exist in this universe, it must be impenetrable,"

Then he looked around

"Even though the room itself is in the centre of the sun, it is actually in limbo,"

This idea came to his mind from Naruto. if someone could sneak into his mind and break through the impossible sun, he wouldn't find anything.

He passed to the third layer. Since he was not in a physical form, he could move between the layers. It was his mind. He was the god of this place.

"For the radioactive zone and solar energy, it was a brilliant idea to transform the memory spheres into atoms and direct the energy in the reaction that would occur when the atoms collided. All that was left was to turn on the computer and load the memories into the core."

Passed to 4 layers

"The layer that will increase the reaction of the radioactive region and turn it into plasmid explosions and scatter ultraviolet rays."

The interface came before him. The computer was essential for the sun to work. After all, he designed the sun and made it work like a machine.

5th layer

"The part where the energy generated by the combustion in the surface layer grows. It will burn forever like Amaterasu. Making it red was the right decision."

Layer 6 was his favourite layer.

"If I put the sun inside my brain and imagine the rest of it as a space, why don't I spread your invisible radiation and torture ignorant wizards? Hahaha cunts try me,"

This idea came from his worst fear. Magic can't be felt. Magic is something that can happen without even realising it. Of course, his interest in physics in his past life also helped.

"Operation time" waved his hand, and it connected directly to the threads in all the memory spheres flying around to the outer layer of the core, and he watched the process from the interface.

There was an estimated time bar created. "It will take two hours for the defence to activate. It's amazing how fast the processes are in the mind."

Two hours watched the process, checking that everything he did was working and functional

"Now I have to make a rule as a precaution, I did make the sun, if I burn it won't affect me, but if I set a limit on myself, will the function in hxh be okay?" his hand was on his chin in the core room in limbo.

If the magic oath existed in this world, the binding and incorruptible oaths should be bearable if the magic

"I swear to my magic and my life that I will never change my mental defence and while inside my mind, I will never leave this room."

He made the sun work as soon as he took his oath. If you were to look from the corner of your mind to the centre, you would die.

If you were to attack his mind, it would disappear as soon as your attack took place, and it wouldn't even exist long enough to get a backlash.

Henry had succeeded, oaths would provide power according to one's potential and will, magic vows would work similarly, but the oath would not provide power. They would be binding, but it should not be forgotten, he had sworn to himself; he had sworn to his will, magic and faith, he wanted an insurmountable mind defence.

"Ahh sorry I'm done with my defence, unfortunately now I'll just have to read minds," as he grins at what would be most people's worst fear.
