A magical journey that begins in Azkaban

Half a year ago, Roger and his mother Jessica began to secretly collect the necessary materials for the snake-man antidote. They used the Travis family's newly opened potion shop to gradually accumulate the required raw materials.

Although their actions were cautious and secretive, as the relevant materials in the market became increasingly scarce, the prices of these materials almost doubled.

Now, as the official procurement of various magic circles began, the prices of some key medicinal materials have soared. Mandrake root, witch hazel and mist dew grass, these originally ordinary medicinal materials, are now sold for as high as 1 Galleon.

As for the less used ingredient, viper snake marrow juice, as the northern hemisphere gradually enters winter, most snakes go into hibernation, making this medicinal material more difficult to obtain. Wizards can only pin their hopes on the search in the southern hemisphere, or the Muggle farms.

Roger smiled and put down the letter in his hand. Jessica has taken this opportunity to put the raw materials in the warehouse into the market in small quantities and multiple times. Just relying on the means of buying at low prices and selling at high prices, their wealth has grown like a snowball.

When the Ministry of Magic completes the collection of raw materials and hands them over to Roger, he will also get half of the finished product. In the midst of the upheaval, almost all of the magic world has been severely skinned by Roger without knowing it.

Of course, those employees who stay in the office every day are not philanthropists. They will not generously provide the precious snake repellent potion to the Muggle government for free.

For every Galleon earned by Roger, they will get it back from the Muggles ten times or a hundred times through other means.

To be fair, this is a systematic, top-down plunder and robbery. According to statistics from some wizards afterwards, at least one-third of the wealth accumulated by Muggles since the Industrial Revolution has been traded to wizards.

Large tracts of land were taken over by wizards, and then Muggle-repelling spells were set up; dazzling gold ingots were pushed out of the underground vault and taken away by wizards in carts... The strong plunder the weak, the living plunder the dead, this is the unchanging law of this world.

In order to get a share of this once-in-a-lifetime feast, Roger devoted almost all his nights and rest days to the transformation of the airship. Even Nagini, who had just regained her human form, was pulled by him to work as a laborer.

"Nagini, hand me the magic thread." Roger stood in front of the airship's control console, dismantling the joystick made by the goblins.

Nagini yawned and handed over a thread with sleepy eyes. Her lower body had changed from a snake tail back to legs, and her white, slender legs twisted slightly unnaturally when she walked.

Although Nagini has returned to her wizard body, many of her snake characteristics are still retained. Her tongue is slender and flexible, her waist is soft as if she has no bones, her body temperature is low, and she always feels sleepy in winter.

Don't ask Roger why he knows all this, because this is the secret told to him by his fingers.

"Master, can I go to bed?" She was wrapped in a thick bear fur coat, holding a cup of hot tea in her arms, squatting on the ground, curled up to resist the cold. "It's too cold, I need a stove and a medium rare steak."

"There will be a stove and steak." Rogge comforted her while connecting one end of the magic line to a black square box, and then dragged it to the tail of the airship.

Based on the original telescopic magic line, Rogge removed the telescopic spell and replaced it with an innovative magic detection function. In this way, he can control the posture of the airship with amazing precision through the input magic power, just like operating a baton.

The seemingly ordinary black square box in front of him is actually the brain and heart of the entire airship. It is the control center and the core connecting Rogge and the airship. At the same time, it is also the starting point and end point of all magic lines.

This black square box has extraordinary ability to transform Rogge's magic and his intentions into complex magic fluctuations. Based on these fluctuations, Rogge developed a corresponding table of numbers to activate the precise runes of the corresponding nodes on the airship.

The flight posture of the airship will then be fed back to the control center in the form of data through the second magic line. Through real-time calculation and comparison, the control center fine-tunes the posture of the airship to ensure that it can accurately respond to Rogge's every thought.

The entire airship will move as a whole, instead of pulling five or six joysticks to turn a corner as before.

In pursuit of extreme accuracy, Rogge also carefully crafted hundreds of secondary proofreading centers. These centers are more compact and simple in structure. Although their computing power is not as good as the main control center, they have amazing storage capacity.

In his carefully designed system, each crystal plays a unique role according to its position, recording and managing the data of its respective node.

These crystals will undergo preliminary proofreading and adjustment before the data is transmitted back to the control center. Not only can it ensure that every piece of information is accurate, but it can also adjust itself.

Over time, the more the airship is used, the more data these crystals accumulate. When the amount of data exceeds a certain point, they can intelligently choose the most effective and precise way to adjust the various functions of the airship.

This design greatly reduces the burden on the control center, allowing it to more effectively manage hundreds of cabins on the airship and keep the airship running smoothly.

To further improve the stability and reliability of the system, Rogge adopted a topological structure that weaves all crystals and nodes into a tightly connected network.

He conducted simple tests, and the results were encouraging: Even if the main control center was destroyed, or two-thirds of the crystals and nodes were damaged, the control of the airship could still be maintained.

When Rogge returned to the control room, he found that Nagini had curled up and fell asleep. Her long eyelashes trembled gently with her breathing, and her thin lips looked particularly seductive in her sleep.

Roger smiled, gently picked her up and walked to the upper cabin. His embrace was warm and comfortable, causing Nagini to turn over unconsciously in her sleep, looking for a more comfortable position. Rogge covered her with a quilt carefully, then turned and returned to the control room to continue repairing the ship.

After several nights of hard work, Rogge finally completed the control system.

Thousands of nodes, hundreds of crystals, and millions of magic lines on the airship are carefully placed in place. This complex airship control system far exceeded the imagination of the magic world, and it cost Rogge nearly one million galleons.

However, its value and potential far outweigh these fees.

Now, the messy joystick has been replaced by an oval-shaped table. The black control center lay quietly in the center of the table, like a heart waiting to beat.

Rogge picked up the wand, tapped it rhythmically on the table, and silently recited a silent and complex spell. Following his spell, the mysterious patterns engraved on the table began to glow, emitting a brilliant but not dazzling light.

The control center slowly rose and hovered at Rogge's eye level, as if paying tribute to him. Then, it released a stream of blue light waves, activating countless magic threads on the airship.

Millions of magic threads conveyed the "wake up" command, and the gray rhombus crystals began to shine with blue light. There was a weak magic wave coming from the node controlling the airship, and the entire airship seemed to be given life.

"First activation...The number of successful nodes is 1658...Failures are 32, 31..."

Lines of data were quickly played above the control center, and all crystals, nodes, and magic lines were tested amidst the vibrations of magic power.

"Sleeping... activated for the second time..."

…

The control center continues to work, constantly adjusting and improving, checking every component of the system.

After twenty consecutive rounds of rigorous testing, including sleep and wake-up, hammering, shock, random and other different working conditions, the control center gave the test results.

The pass rate of the crystal is as high as 95%, the pass rate of the node is 93.7%, and the pass rate of the magic line is an exciting 98.9%. These numbers prove just how sophisticated and reliable Rogge's creation is.

He breathed a sigh of relief and instructed the control center to print out the addresses that could not be activated or failed the test. He checked and re-replaced or reconnected the parts one by one according to the printed numbers.

"Test again, number of tests: 100." There was a hint of unnoticeable excitement in Rogge's voice, and he knew that he was one step closer to perfection.

"Master, can the airship fly?" Nagini heard the noise and ran downstairs impatiently.

She curiously looked at the countless magic light spots in the control room, her eyes flashing with shock.

"Still testing, it will take about 15 hours." Rogge smiled and asked the Hufflepuff Gold Cup to deliver a dinner.

After curing the blood curse, this was the second time Rogue used Muggle knowledge and wisdom to create new magical things.

He drank a lot of milk and rubbed his sore eyes. Although his body felt tired, his mood was extremely happy and his appetite became particularly good.

"It will take so long. My fireplace will have to wait for a long time." Nagini couldn't help but show disappointment. She squeezed into Rogge's arms and greedily felt the warmth.

"I hate winter," Nagini complained, with a hint of coquettishness in her voice.

She turned around and put her two cold hands into Roger's clothes. "It's so warm, Master~" she murmured softly, her eyes shining with dependence.

Rogge looked at the stars in Nagini's eyes, then looked at the steak and mushroom soup on the table, and he understood deeply what "beautiful and delicious" meant.

His hands naturally climbed up to Nagini's waist, and she clung to him like a beautiful, boneless snake.

"Master... um..." Nagini's voice was soft and seductive.

"It seems inappropriate to always call you Nagini." Rogge said suddenly.

"Why?" Nagini's breathing became rapid, and her eyes were full of curiosity, "Master, do you want to change my name?"

Rogge lifted up her bearskin coat and couldn't wait to share the warmth with her: "I investigated your identity as a wizard before you completely transformed into a beast. Your real name is Maledictus."

"Maledictus?!" Nagini's eyes flashed with suspicion, and there seemed to be a familiar voice echoing deep in her soul.

She seemed to have remembered something, and her happy face was mixed with a bit of sadness and contradiction. The body that was freed from the blood monster was a little cold, which made the masculine heat in the body even more majestic.

"Master..." There was a hint of uncontrollable desire in her voice, as if she was seeking some unknown satisfaction, "Can I... have more?"

"More?" Rogge paused deliberately, his fingers gently sliding across Nagini's smooth back, as if he was thinking about her question.

"You were born with a blood curse. Whenever night falls, you will turn into the form of a snake." His voice was low and magnetic as he continued to tell her about her past. "You were arrested in that state. Then he was sold to a witch circus."

"Circus?" Nagini turned her body and naturally performed a difficult movement.

One of her legs lies gently on the ground, while the other is raised high, demonstrating her flexibility and strength.

Nagini's outstanding physical talent, coupled with the residual influence of the blood curse, is simply the most perfect dancer created by magic. Whether she is standing, lying down, or in other positions, she can give Roger the most perfect experience and enjoyment.

"Don't call me Maledictus, okay?" Nagini's eyes were locked tightly on Rogge, with a hint of pleading in her tone: "I am Nagini, the master's Nagini."

Rogge's movements paused, and then he responded to Nagini in a more wild and direct way. Every entry and exit was full of strength and determination. He accepted her allegiance and showed her that he would never leave.

Whether she had been a viper in the Indonesian rainforest or a blood beast in the circus for the entertainment of wizards, now she was Nagini.

She was saved by Rogge from the curse of the Blood Beast. Her name, her body, and her soul all belong to Rogge Travis. He was her only master, there was no doubt about that.

Rogge deeply understood Nagini's thoughts. He released his spiritual power without any reservation and tightly wrapped the warm body in his arms... The waves of the Shetland Islands came one after another, The surge was violent and continuous.

The black console has completed the self-test, and the pass rates of crystals, nodes, and magic lines have all reached 100%. As a green light flashed, the console gradually transformed into the shape of an airship.

Rogge took out the wand from the pile of clothes in his busy schedule. After it emitted a milky white light, the black airship model immediately became colorful.

As the colors of the airship model gradually became richer, Rogge's mood was like that of the airship, about to take off. He paid close attention to every detail, making sure everything fit his design. Nagini was standing aside, her eyes full of appreciation and admiration. She knew how much effort Rogge had put in for this moment.

Roger's wand waved again, this time a blue light, which gently touched every corner of the airship model. The model began to glow faintly, as if responding to Roger's magic.

The goblins created the shell of the airship, but it was Rogge who gave it its true soul.

The two of them stood in front of the console, Nagini wrapped around him like a snake even in her human body.

Roger's fingers gently slid over the console, and every instruction was accurate. Nagini held his other hand tightly, she could feel Roger's nervousness and excitement. All these efforts are for the coming moment.

Under their gaze, the airship model slowly rose into the air. It circled in the air for several times and then floated stably in the air.

Nagini couldn't help cheering and screaming, and she was pushed down on the long table by Rogge. The two looked at each other and smiled, their eyes filled with pride and joy.

Rogge turned around and hugged Nagini tightly, their hearts pressed together.
