Manga World: Bringing Steam Technology to the World of Sanctuary

Time flies and Christel has spent the months from April to mid-July at school silently practicing the Sightless Eye cultivation method. Now she feels that her mind is clearer, she can see at a distance of around a hundred meters with her eyes closed, that's what those immortals from the dragon country would call it - spiritual perception - now her arrows can hit the target from angles that would be physically impossible.

Christel has also improved her learning of life and death magic and has not let Master Malachar down. She can now raise a small battalion of skeletons with melee weapons and skeletons with bows, although if she wants to summon a skeleton mage, she can only forget about the others. Her mastery of skeletons has made it possible for her battalion to now cleanse the cave of evil on their own.

His bone armor is now strong enough to withstand the fire bullets of the modern world, though it falls to pieces with one hit from the Barbarian and the Paladin. What else can he do, facing the blows of these guys is very heavy and difficult to resist. The Barbarian is pure brute force and the Paladin has divine energy that has great damage against Christel's necromancer magic and that's only when he doesn't add his own mysterious energy to the bone shield.

Her Tooth Summon has not only enhanced the arrows fired by Christel, but she can now summon weapons such as swords, spears, and tooth axes and lend them to the rogues. Her Curse of Weakening is now so strong that if she throws a needle at a Fallen, a huge hole will appear in their body as if they were pierced by a modern sniper rifle.

Not only has she progressed in her training in necromancy, but Korgar has also taught her the fighting method of Mount Arreat, guiding her on the path of using the enemy's power against them. Christel has learned a series of agile hand-to-hand combat attacks in much the same style as Wing Chun. Korgar has also taught her the use of heavy weapons and how to use them in harmony with her body.

What Korgar did not teach him was the art of range, although he was good at throwing axes and bullets, he left that to Zara Ethrida from the Amazon Islands, an expert in the bow and spear. Only days after Korgar and Malachar, the Amazon Zara arrived at Camp Rogue, as well as the Sorceress Lyara Thalor, the Paladin Sir Valen Darnell, the Druid Fenrir Lykaios and the assassin Shira Hanasaki.

Thanks to having a base with Akara and Malachar, learning with Lyara flowed naturally. It's like having a teacher who teaches you geometry, then another who teaches you math, and finally the physics teacher who, with the help of the previous two, you understand it faster. Sir Valen was the most complicated, as was Fenrir, one wanting to teach his sacred art to someone who does not have faith in any divine being, but has an energy that is no less strong than that granted to him by beings of light and another wanting to teach his druidic art to someone who has a lot of vitality, but does not believe in any god of the forest.

Christel quickly became familiar with Shira's teachings, using what she learned from Korgar in hand-to-hand combat and weapons and with Zara's help in the use of the inner eye, the shadow arts and her assassin martial arts have merged very well. She can say that she is now a hexagonal warrior without any weakness in any of her attributes.

In these three months, Christel has not only dedicated herself to learning from the heroes of the world of Sanctuary. With the help of the Demon King Serafall tool, Christel managed to synthesize two samples of silicon crystals to the highest purity without squeezing all of Sera-chan's power, one that represents 1 kilogram and 1 liter and another that represents 1 meter. Obviously, she cannot take these objects to the world of Sanctuary. With her experiments to see what she can and cannot take, Christel has closed her aura, or what she has called her "Biological Field", to six millimeters from her skin and she believes that it is increasing.

So Christel had to bring a 30-centimeter ruler made of silicon crystal, the problem is in the volume to represent the -Litre and the Kilogram- and with 5-millimeter cubes to make exactly one liter and one kilogram she would need eight thousand of these cubes. It took Christel more than 10 days to put almost a thousand cubes the size of small marbles in her clothes per day to transport them to the other world. And all this while also sending fruit and vegetable seeds.

With the help of Sir Valen and the wolf Fenrir, lands have been opening up around the camp and the cave, where Christel now lives and spends most of her time when she is not outside hunting infernal creatures. Something that has also brought problems to Christel, or rather, to her demon friends that every time she arrives at school, she is stained with dark energies left by killing Fallen and other things, which has caused Rias and Sona to almost move to Christel's house with not only the arrival of Serafall to explore the surroundings, but she has also met Grayfia Lucifuge, the best in magic along with Serafall, but not even the two working together have managed to discover where the dark energy that appears in Christel every morning comes from.

Christel can only shrug her shoulders, she has been practicing to cleanse her body before falling asleep and traveling, but there is always residue left, and the -Masters- do not want to help with that, they let Christel solve it, as part of her training.

With the help of the silicon crystal ruler, Christel has made plans with scrolls purchased from Warriv, with whom she has dedicated herself to selling the resources she collects from monsters and then using the gold obtained to buy scrolls and inks for her plans from Warriv or Gheed. These capitalist merchants are not going to leave here until the Eastern Pass is opened or it is safe to pass through the Dark Forest.

And so with the help of Christel's plans, Charsi has found that she can create interesting things with metal and not just weapons and armor. When the first water mill was built, Christel told her that it is called a "Water Wheel" and she knows that she has seen these water mills in important cities, but she would never have thought that lightning could be generated with it. Christel also managed to create a vacuum light with the help of the water wheel as a driving force for an air pump. Then with a series of materials that Charsi created with her intrusions, the first incandescent light appeared in the world of Sanctuary and illuminated the camp. The light was large, one meter in diameter and she placed it on top of the largest tent that functions as a command center.

This light alone illuminated the entire camp and can be seen from afar as a beacon. With a rustic voltage controller, the light can be made to dim at night to let everyone sleep or to turn up the intensity if there is a night attack. Something that has been noticed not only by Moreina, but also by Andariel, with no few confrontations with the corrupted rogues and with Moreina asking Akara what kind of magic is that. Of course, Akara can't answer even if she wanted to, because she doesn't understand it! But she knows that this invention can be a very strong weapon. It's not magic, but it creates so much lightning energy that it can kill many rogues in an instant. Christel has explained over and over again how dangerous this is if you're not careful.

Christel's short-term goal is to create the first "Tesla Tower." She doesn't want to have to deal with the problems of cables as she has the crudely connected light bulb now. But she still needs to create precision tools before creating the "Tesla Turbine." Charsi doesn't leave her smithy much, melting and hammering with the help of other blacksmith apprentices. Charsi feels that Christel has opened up a new world for her in metalworking and she has been very excited all this time.

Lyara has tried to control the electrical energy coming out of the hydraulic turbine, but she is impressed every time, she says it is like trying to control the lightning bolts in the sky, so chaotic and unpredictable. And although Lyara as a sorceress has great knowledge, and knows why that energy can be generated, she is still impressed to see that it is only a black stone tube that has the ability to attract metal and is only used as a toy and in compasses it rotates inside another tube of copper cables wound countless times, cables wrapped in tree resin that took a month to make.

The Valley of Hope (formerly Blood Wasteland) and the Cold Plains have been conquered and cleansed by the advance parties of the Rogue Camp of each hero team plus Alysha, with Christel as a wildcard taking turns in the groups practicing the skills under the hero's training without using the skills of another hero, it was with consensus that everyone came to an agreement to train Christel, under the leadership of Akara who now believes more firmly that Christel can bring great change to her world.

And so, the day before summer break arrives, where students are receiving their mid-year exam results.

"Wooa~ Christel, your grades are perfect as always..." Ruruko taking Christel's test papers and comparing them to her own.

"Mm..." Koneko with her usual manner of expression like a porcelain doll, but within her eyes there is an emotion of imbalance. 'Koneko with grades at 80 points, Akeno will tease her again...' Christel glanced at Koneko's test marks but didn't say anything.

"How did it go Ravel, you like to come to my house to study, I hope your grades are better than Ruruko's 70 points..."

"ugh.." a moan is heard but everyone ignores it.

"I did great, I usually get passable grades, but now I have over 80 points..." A fiery golden-haired Ravel shows a look of pride at her results.

"...WoW Christel-san has perfect grades..."

"Amazing, how you did it Christel-san..."

"...Christel-sama I want to study with you next time"

"Christel-sama I want to go on vacation with you to study..."

"I want to go with Christel-sama to the beach..."

"...I want to lick Christel-sama"

"..."

Ignoring the person who said the last thing, Christel invited them to come to her house or she could go to the amusement park sometimes, but she was mostly going to be busy on vacation. She has the science and technology fair next week and her projects are almost ready. Her small Tesla turbine will be presented as an independent, and the touch screen technologies, high capacity lithium batteries, etc. by the company - Fantasy Mahou Shoujo Kabushikigaisha - are already ready to be shipped.

After saying goodbye to her classmates and promising to meet up, Christel went to the old occult club building as she normally does on Mondays, Wednesdays, and Fridays, with Tuesdays and Thursdays going to the student union. Plan proposed by Sona and Rias taking advantage of having Christel 3 days a week because she went to their club where she joined first. Sona just clenched her fists, Sona knows what Rias does with Christel in a few moments a day, but she has no choice but to keep quiet since she herself has taken advantage of the discovery that was made by the girls who have stolen a kiss from Christel, either by accident or on purpose.

Rias, at that moment when she wanted to force Christel to join her club and accidentally tripped and her lips crashed into Christel's, after calming down she noticed that her power of chaos and her demonic magic increased a little. Something that all the other girls have also noticed, and they have communicated it to each other. Especially Maria who is the one who takes the most advantage of Christel and has already taken the final step with her. Maria's succubus magic has increased by leaps and bounds that it also caught the attention of Sheila, Maria's mother, to approach Christel creating casual encounters on the street when Christel goes shopping or running an errand.

Sheila, as Mio Wilbert's father, gave most of her power to Maria when she was born. Although Maria's power is sealed for the most part, it will be unlocked as Maria's power grows, with an emergency system where Maria can transform into an Adult and use Sheila's power at will for a short period of time.

But as one of the strongest Succubus in the Akuma world in the Makai realm, she feels uncomfortable being in a weak state, although she does not regret giving her powers to her daughter Maria, if there is a way to recover to the level of her peak, she will use it. So sometimes Christel is attacked by a little girl who seems to be Maria's twin sister, but with a more mature character, and who steals kisses from her sometimes.

.... Occult Research Club....

"..."Ah Christel, come, what do you think of the final plan for the haunted house?" Rias asked the little golden-haired girl who entered her study.
