Christel, putting aside the thought of Lycander and why he would pass on that method of spiritual cultivation to the twin daughters of an ex-love, focused on the defenses of the Cold Plains.
One of the core technologies in the post-apocalyptic world of They are Billions is concrete. Unlike in the 2008 Manga World or its previous world of the blue-water planet, it was not comparable to the formulas used to make cement 500 years after the end of the zombie world.
Creating walls that can stop not only an Infected Fatty, but an Infected Giant is a sign of high technology in masonry and chemical mixing of cement. Inside Christel's mind, there is the technological tree that goes from quarries, Synthesis tools, chemical formulas to experiments with materials such as nanotechnology, carbon and even using infected biological materials. From these latest experiments, walls have been created that can withstand the impact of Giants.
Obviously in the world of Sanctuary there are no such things as zombies where you can extract building elements, but there are plenty of fallen and other creatures with supernatural abilities and resilient bodies.
Although masonry exists in the world of Sanctuary, most of its forms are made of rocks and stones. Legend has it that the Tower of Babel used cement and almost reached God. Cement has also been used to create ships, and although Tintan's ship sank, it is a technology that has been shown to be feasible.
After showing the possibilities of cement and the importance that Andariel surely gave to those caverns to place Coldcrow as a guard, and even send an avatar, Christel decided to turn that cave into a Limestone and Clay mine and protect it.
"But... Christel, I really like your construction plan, there's just one problem."
"Sister Akara, tell me"
Everyone in the new meeting tent outside the former evil cave and now New Hope Research Center turned their gaze toward the High Priestess.
"...We do not have the personnel to manage the mine or manufacture cement"
"Sister Akara, we have this!... -Summoning: Skeleton Resurrection-"
Obviously there isn't a corpse nearby to summon an undead, but Christel has a small battalion standing guard around the new "Camp New Hope" (temporary name), so even though Christel said the incantation, she actually only called upon two skeletons standing outside. Unlike Malachar's skeletons and summons, the creatures under Christel's control are injected with a bit of her power, which sets them apart from orthodox necromancers.
Christel's skeletons have much more autonomy and follow more complex orders, many of the buildings in their new camp and inside the cave have been created by the skeletons under Christel's command. Another thing is that, when Christel falls asleep or faints, the summons do not disappear when she travels back to the Manga World, and will be there without any change when she comes to the Sanctuary world.
"That's true, though. That's why I'm planning to take control of the River first. As you know, the river that runs past Rogue Camp can reach Rogue Monastery and flows into the -Gulf of Westmarch-. There have been traders from -Sharval Wilds- and -Westmarch- passing through these months, although very few. But the news that we have control over these lands and that they are now seen as fertile lands will attract more traders and immigrants. If we manage to build a dock at the river delta and expand it to accommodate ships, we'll have a great method of transportation and control..."
Christel pointed at the now larger and more detailed map that had been placed on the round table. Although Christel wants a sand map, she will have to wait for that yet. But for now it is enough to continue guiding the steps in the plan to conquer the lands of Khanduras.
Jaina, Alysha, Elly, Fiona, Mahala, and Shikha, the former raiding party that welcomed Christel to the world of Sanctuary, have now become her guard. After seeing her run into Coldcrow and fight a shadow of the Grand Demoness Andariel and fall unconscious under her curse of sin, they have now decided, with Akara's permission, to stay by Christel's side.
Now the girls look at Christel and are amazed at her ideas and plans, as if the whole area is looking down from the sky as if it were the palm of their hand. Jaina feels more and more affection for the golden-haired girl, and when she saw her fainted in the arms of the Amazon, she felt her heart break.
Alysha, on the other hand, has enjoyed learning and studying administration and organization, as well as project planning, with Christel. Although she has not forgotten her goal of being as strong as her Mother Kashya, she has also acquired the goal of being a great leader.
So Christel has been practicing the heroes' skills on a rotating basis, and then using her skeletons and clay golems to expand the river. And her only regret is that the river doesn't pass through her cave.
Now, Jaina, Alysha, and the other girls will be spending more time with Christel as her guard. Although Alysha threatened Christel within the first week of their acquaintance that she would take her as her wife, the truth is that they have been so busy, between training and missions to clean up the wasteland and the plains, that their relationship has grown at a slow pace, with only Jaina being the one she spends more time with if you count sleeping together.
The relationship between Christel and the chosen heroes is also very good, each hero, after training Christel at the beginning, has gone on to practice and learn together, with modern knowledge of chemistry and physics, their combat method has been systematized. Not to mention the knowledge of the following releases of Diablo III, Diablo IV, Diablo Immortal, etc. with which, each hero has become very versatile now in the handling of their skills, and in the future they will be even more unrecognizable from the characters of Diablo II.
And personally, each hero has his own taste, and Christel, with her knowledge of social observation, has known how to attack each one of them from the right angle, talking to them about mythology and various characters that deal with the forces of life and death in different ways, like the Shinigamis for example for Malachar. With legends of gods that control the various elements and take them to the level of universal law like the gods of Olympus and their father god Zeus for Lyara, like the Druids of the, surely, neighboring planet Azeroth, the plane of the void and the dimension-eating worms that live in the interdimensional zones, and the Paladin in... well, the paladin is the same everywhere.
Zara likes the story of -Diana Prince- aka. -Wonder Woman- and of the hero girls she is the most talkative and relaxed, she seems like the female version (definitely beautiful) of Korgar, two people who spend their time drinking alcohol with Charsi when they are not practicing or doing hunting and cleaning missions.
Speaking of Charsi, she and her group of blacksmiths have made advances in woodworking machinery. Although they still use the mechanical energy transfer method of the water wheel, of which there are now three on the river, their Blacksmith area has been converted into a Carpentry Workshop. Christel has given her plans to make various types of lathes with saws, drills, etc. with exact measurements to be able to work the wood and make construction easier and faster.
This is very important, since in Christel's plan, ship building is a crucial step. And she doesn't underestimate wood, in the world of Sanctuary, there are trees so strong, that a ship made from the wood of those trees, will have more defense than a steel battleship from the blue water planet. Only, the wood of the Black Tree, is much harder than iron and is fireproof and hydrophobic, with a perfect kiss to be stable at sea.
The technological branch in carpentry in They Are Billions is also advanced, since with the mutation of the species after 500 years of living with the virus -Rabies_Z-, not only the animals have evolved to adapt, but also the plants, therefore, the trees, creating harder and more resistant wood. With the various treatments with specialized compound liquids, it has made the wooden constructions in the world of They Are Billions stronger than any cement and steel construction on the blue water planet.
On Friday morning Christel woke up, with a normal routine, she had to take the train to Tokyo, the fair is on Saturday and Sunday. But since Raynare had something to do today, and Usagi wanted to have a date, she agreed to spend Friday in Tokyo with her and wait until nightfall to travel with Raynare who told her that she would meet her in Tokyo.
Reiko will also be waiting for her in Kyoto. Christel wonders how the leading technology and entertainment companies will react to her proposals. Maybe they will ignore her, maybe the only ones paying attention will be Microsoft and Apple.
"Child, remember to call Mom every night and every morning, don't wander around Kyoto alone without Reiko-chan, and call me if anything happens, and..."
"Yes, mom, stop kissing, I'll miss the train. Mio, I'll leave the house in your hands, don't let Maria or Lala destroy it. Yami, I'll leave the security of the house to you."
"Mm" Yami with a frozen face without expressions just answered.
'Because I feel like I'm seeing a Koneko, but with blonde hair and more... more grown up...' If Koneko knew Christel's thoughts, perhaps she would express anger for the first time.
"Well, I'll be leaving, I'll be back in two days... Lala, Maria, you should let me go..."
.... After a wave of goodbyes, Christel finally left home and arrived in a private vehicle just in time to catch the train to Utsunomiya and from there on a special line to Tokyo. She then traveled a distance in 2 hours, when she got off it was already 10 in the morning and Usagi was waiting for her with Luna in her arms.
"Christel, here!" Usagi, seeing the girl with light pink eyes and blonde hair, but at the same time more golden than hers, got excited and shouted her name with undisguised happiness. It is the first time she has brought a single girl to sleep at her house, and when she thinks about it, she feels nervous about introducing Christel to her parents.
"Hello, Usagi, sorry I'm late..."
"Umm no, I just got here." 'I came early, but I can't help but feel nervous, but very happy.' The pink-faced magical girl Sailor Moon shook her head. 'How does this feel like a love date...' And thinking about it, her face turned from pink to red.
"Shall we go to your house first?"
"Yes, you can leave your luggage at home and then I'll show you around and my school." Usagi saw the pink suitcase that Christel was dragging, she thought about going home first, then she could introduce her mom, dad Tsukino is not at home, he went out to work, since he is an editor of a magazine and sometimes takes photos.
"Luna, I can't carry you now, I'm dragging luggage..." Touching Luna's head and stroking her chin and ears, Christel said to the little black cat in Usagi's arms, who seemed to want to jump towards him.
"So, come on Usagi, I'll follow you." Then taking Usagi's hand, Christel walked with her towards the exit.
"...Yes" Usagi only answered with a shyness and felt her heart jump out. She squeezed Christel's hand and walked, but suddenly she felt Christel stop, and when she turned to see her, she was looking in the direction of the Train Station.
"What's happening?"
"Oh~ nothing, I just seem to have seen someone I know... Let's go"
And so, Christel just ignored it, and headed for the exit under Usagi's guidance, as they began a casual conversation. But in the distance, twelve heads peeked out, divided into two pillars.
"Ufff~ He almost noticed us"
"Kaicho-sama, that's because you let out an aura when you saw Christel holding someone else's hand hehehehe~"
"Wh... What? Me? Sona is where the overflowing demonic energy came from..."
"Rias, what do you mean by that?
"Sona-sama, don't fight, Christel will discover us.
"So, who has Christel's itinerary with that Usagi girl from a foreign school?" Sona put on a serious face and with her right index finger she put her glasses back in place, pushing them out of the way on her nose.
"To say that he is a foreigner is excessive, and I think the foreigner is Christel."
"Yuuto (Kiba) Shut up!!!" x10 Yuuto felt the pressure of eleven girls was too much, eleven because, although Koneko did not speak, she also gave him a look with cold eyes. 'How scary, I would have been better off staying with Gaspar'
"By the way, why is Ravel accompanying us?"
"Why... Why can't I come, Christel is my classmate!"
"Uh, girls, Christel has already left the station and is walking away."
"Quick, chase, who knows where that girl from another school lives?"
"Rias, aren't you supposed to be the research club, why haven't you investigated anything?"
"Sona, what do you mean by that?"
"..."
Christel felt someone watching her, and when she turned around, behind a pillar she saw a so-called scarlet-red hair, then, activating her spiritual perception. She saw that behind two pillars, there were the Occult Research Club, and the members of the Student Union on each pillar hiding. It seems that they decided to secretly follow Christel out of concern. Normally they don't leave her unguarded, much less let her go alone outside to a far away place. Last week they found out that Christel had run off to Tokyo to play with her sisters and her sisters' classmate Yuuma Amano. And paranormal events happened! This time they would go after her, but who would have thought that the other group would come too. 'And Ravel-chan is coming too?'
