Alan has been very thoughtful about the arrangement of this tower, and now there is only one question, and the most important question, how to let his trusted relatives and friends enter and exit this tower freely?

Alan flipped through the books in the Black family's collection, combined with the knowledge he had mastered, and had a more mature idea.

He saw an interesting marker magic, perhaps Voldemort had seen it before.

Voldemort imprinted this mark on his subordinates, and he called it the Dark Mark mark.

According to what Allen saw, the graphic of this mark could be designed by himself.

Apparently, Voldemort had chosen a terrifying figure that would scare others - a huge skeleton made up of countless turquoise star-like things, and a large python emerged from the skeleton's mouth like a tongue.

Everyone who joins the ranks of the Death Eaters has this Dark Mark on their left arm as a sign of identification.

Alan couldn't be sure of Voldemort's aesthetic, but he had to admit that his purpose had been achieved.

This sign brings panic to countless people.

Because in those dark days, whenever he or his Death Eaters killed someone, they would leave a dark mark on the top of the corpse or house.

Not only that, but every time Voldemort was powerful or around him, the markings on the Death Eater's arms would burn like a burning pain, and would become clearer and clearer, turning red.

As soon as Voldemort pressed the Dark Mark on a Death Eater's arm, he summoned other Death Eaters, at which point they immediately apparitioned and appeared next to Voldemort to obey his orders.

When a Death Eater touches the Dark Mark on his or her left arm, Voldemort can sense the summoning and apparition to him or her.

In Allen's eyes, black magic is just a type of magic, and its value cannot be denied just because it has been used in a bad way by ambitious people.

Don't choke on food.

The more we fear something, the more we should study it.

Because what we are afraid of is often not the thing itself, but the unknown.

The more Alan studied the dark arts of the Black family, the more he was amazed by the subtlety of magic.

For this marking magic, Allen felt that it should not be denied its value just because Voldemort used it.

Allen thinks it could be of a great use, such as being used as a key to get in and out of the tower.

Allen thinks that the touch markers, the ability to communicate with each other, are very useful.

Think about it, if your relatives and friends need your help, wouldn't it be very safe for you to be there for them immediately?

Moreover, if you touch the mark when you encounter danger, you can instantly phantom and return to the tower, but the opponent cannot enter, does it add an extra layer of protection to your life?

Then Alan has a very important problem to consider - he needs to design a graphic that matches his own aesthetic for his mark spell.

Voldemort's graphics are meant to be mysterious, to make people feel frightened, to be afraid, to be able to create panic.

Allen felt that the figure should first represent himself, and secondly, it should be able to reflect his own philosophy.

After repeated designs, Alan looked at the finished draft in his hand and was very satisfied.

The elements of this figure are: a ruler, a two-legged ruler, a clasped hand, and an omniscient eye.

The ruler represents the downward triangle in the six-pointed star, which means truth, while the two-legged gauge represents the upward triangle, which means morality, secrecy, and faithfulness.

The handshake represents trust and is placed in the middle of the ruler and the foot gauge.

The two-legged gauge and the intertwined hands make up the letter in Alan's name - A.

Between the hands and feet of the hand, there is also a golden letter, H, which corresponds to Allen's surname, Harris.

At the top, the all-knowing eye is an eye surrounded by triangles and rays of light.

It represents perception, gaze, secrecy, protection.

Thinking of the inquiry room at the very top of the tower, it is not difficult to imagine the interest and importance that Alan attaches to this omniscient eye.

Alan gently rolled up the sleeve of his left arm and printed the designed omniscient mark on his arm.

The golden markings gleamed on the arm, and then regained its calm, as if it were just an ordinary tattoo.

Only when activated with magic can you feel his magic.

Alan looked at the omniscient mark on his arm, overjoyed.

Suddenly, he frowned again.

If you want to promote this tag, you have to differentiate your features.

Shall all those who are marked be allowed to go freely to and from his tower? Walk through the city gates? Absolutely not!

There are so many precious materials in the tower, so many secrets, it is not a completely trustworthy person, and it must not be easily entered.

Alan thought about it for a moment and made another version with the exact same pattern as the omniscient mark he had designed, except that the clearance was reduced and he was not allowed to enter or leave his tower.

This version only uses the original function of this spell, with no changes, and is similar to Voldemort's Dark Mark function, except for communication, communication, and phantom shifting positioning.

Allen, immersed in laying out the tower and researching the markers, left the tower happy until he had finished his research at this point.

The whole of Hogwarts was very peaceful, and before I knew it, Alan was staying in the Room of Requirement until late at night!

Despite this, the excited Alan is like a child who has been given a new toy, like a male Muggle who has just bought a new car of his choice, and he desperately needs to confide in someone he trusts, to share his achievements, his joy.

However, the night at Hogwarts was quiet, and no one could share the joy of victory with Alan, who felt a little lonely.

There was a hot current in Allen's heart, and he couldn't wait to share it with others.

And the most trustworthy - naturally are the family members who have made an unbreakable vow.

Alan made a quick decision, directly took out the fire crossbow arrow, and after stealth, flew towards the outside of Hogwarts Castle.

Leaving the confines of the castle, Alan has an apparition and appears at his doorstep.

In the silence of the night, Mr. Harris's family suddenly became lively.

Everyone gathered in the hall in their pajamas.

Seeing the undisguised joy on Allen's face, everyone knew that Allen must have good news.

Alan unleashed his tower and took his family to visit it floor by floor.

This is worthy of a family, and the expressions on everyone's faces are extremely similar, they are like falling into a dream, and after the incredulity on their faces, they are eager and ecstatic.

Clever Harris naturally understand what this means!

On the top floor of the tower, all the family members were stamped with Allen's omniscient mark that they could enter and exit the tower freely.

However, Emily has not yet learned to apparate, so she has to rely on the rest of her family to bring them in.
