I've been rereading svsss, playing fallout 4 and watching the new fallout show so here is my svsss fallout au! (I don't know if other people have already thought of this but I just had an idea and had to set it free into the world, also this isn't a fic or anything it's just a plot and a little bit or worldbuilding)
Disclaimer I couldn't include every plot point and some stuff had to be changed to better fit the fallout setting
Shen jiu and shen yuan are brothers living in a town for vault tec scientists and their families similar to the start of fallout 4, shen jiu is a vault tech scientist and shen yuan is a teacher at the local school. Luo binghe is one of Shen yuans students who moved in with shen yuan after his adoptive mother passed away, Shen jiu doesn't like Luo binghe much but as he's often away working binghe is both a student and companion to shen yuan who dotes on binghe. While she jiu is home the bomb drops and he, Shen yuan and binghe have to escape to the vault with the rest of the scientists (cang qiong sect) and are put into deep sleep cryopods. After some time when yuan wakes to see raiders opening Luo binghes pod and dragging him out, while conscious when yuan is unable to escape his pod to get to binghe however some other pods have also been opened, including Shen jiu’s he desperately tries to protect when yuans pods from the raiders who have been drawn to his attempts to escape. While trying to protect his brother Shen jiu is shot and killed, the raiders retreat and the cryopods reactivate forcing everyone back to sleep. Some time later the cryopods open and all of the cang qiong scientists and their families are let loose to run the vault but shen yuan and yue qingyuan are inconsolable, Shen yuan tries to confide in his close friends Liu qingge and IT analyst Shang qinghua however as time goes on qinghua becomes more and more nervous causing Shen yuan to feel more alone than ever. Finally shen yuan snaps and decides to find Luo binghe to save him, yue qingyuan has almost entirely withdrawn and poses no resistance so shen yuan sets out with liu qingge and Shang qinghua. After passing through the wreckage of their town the group immediately run into a firefight between raiders and a group of freedom fighters known as the minutemen, they aid the group and learn that these minute men intend to set up a settlement by the cang qiong vault which would provide security to the vault and safety to survivors. Liu qingge reluctantly joins this group in order to protect his family and home but only does so after insistence from Shen yuan and shang qinghua (note that Shen yuan could get the power armour as you do in the game but idk I feel the story can work with or without power armour heck maybe liu qingge takes the power armour to protect the settlement and help the minutemen further). The minutemen have only limited information but point the duo in the direction of diamond city, the nearest major settlement, the two travel through the wilds to get there but outside the city limits they are ambushed (either by raiders or ghouls) and Shang qinghua is taken allowing Shen yuan enough time to escape and reach the city walls.
Once inside she yuan seeks the help of an elusive private detective and is sent to aid him in a fight outside the city walls, Shen yuan provides aid and saves the life of a wounded detective by the name of zhuzhi-lang who in turn aids Shen yuan, providing information on an organisation known as the institution and are linked to disappearances and kidnappings. With the help of zhuzhi-lang Shen yuan makes it to one of the entrances to the institution however he is surrounded and arrested, taken deep underground to the cells of the institution. Deep within the institution shen yuan is visited by a grown Luo binghe, Shen yuan is overjoyed at reuniting with his lost student especially when binghe frees him from his cell and takes him into the viewing level of the institution. Here when yuan tries to catch up with binghe and quickly realises that he has changed quite significantly, making subtle comments about the fruits of his family's labour paying off which shen yuan brushes off albeit a little confused. Suddenly the institution is on high alert and people are streaming in killing everyone and anyone that crosses their path, binghe and shen yuan watch from above as chaos reigns, binghe assures when yuan that they're perfectly safe as this is his doing which does little to calm when yuan who has just watched the destruction of a society. When the bloodshed ends binghe takes shen yuan back to his fortress, the headquarters of the brotherhood of steel (kind of there's a bit of divergence with the brotherhood from fallout canon). Binghe reveals that he controls the brotherhood of steel as well as ghouls of the wasteland, furthermore binghe shares that during his childhood he had been a test subject for a vault tec science division (tianglang-jun wasn't a normal human I just haven't decided how he's not normal), here they experimented on him and treated him as a lab rat all following the orders of the team leader shen jiu. Binghe had been taken from the vault when institution scientists found records of this experimentation and the location of the vault and felt that binghe had the possibility of being a living weapon that they could mold. Shen yuan is devastated, his sweet innocent student had been treated as nothing more than a living experiment at the hands of his beloved brother who had sacrificed himself to ensure that when yuan could survive, he's confused and struggling to comprehend his emotions when the fortress is attacked. Word had spread that the brotherhood of steel had abducted a vault dweller matching Shen yuans description and so the minutemen and cang qiong survivors attack the headquarters to try and save him, in the firefight Shen yuan is grievously injured trying to protect binghe and in his panic binghe is distracted enough for liu qingge and mu qingfan to take shen yuan and use stolen institution teleportation technology back to cang qiong.
Shen yuan is in critical condition and requires medicines not available in the vault or settlement, however he is saved by a very unlikely ally, Shang qinghua, who had been communicating with a ghoul overlord by the name of mobei-jun, as an IT analyst and accountant for vault tec he had discovered about the experimentation program being run on children like binghe, mobei-jun and Shang qinghua; although he was being held in the north laboratories Shang qinghua managed to send secret messages to a young mobei-jun who was mutated enough to not only survive the blast but grow incredibly strong. Mobei-jun had received messages from qinghua upon cang qiong awakening and when he emerged to the surface mobei-jun had him brought to his stronghold in the North, Shang qinghua was pretty chill with however felt that maybe letting Shen yuan think he was dead wasn't the best idea so after gathering many rare and medicinal plant samples which had evolved following the bomb he returned to cang qiong. Here he found a critical Shen yuan and using the medicinal plants brought from the north he was able to help his friend not die, unfortunately no one told Luo binghe that. The brotherhood of steel attacked cang qiong in an attempt to take shen yuan’s remains (I reversed it because it worked better), the settlement is reduced to rubble and Pandemonium has erupted into the surface with cang qiong fighting Luo binghe to the last, this is until shem yuan breaks out of the bunker and calls for a ceasefire which is granted as Luo binghe couldn't steal a corpse if he wasn't dead. Shen yuan takes binghe to the wreckage of the house where they had lived in what they believed to be peace, they talk and talk and finally understand everything that they have gone through (I'm making the idea and I say they get healthy communication), it's here that Shen yuan realises that he feels a bit more than familial love for binghe. It's not perfect, binghe is still very much a morally grey person and shen yuan has lots of unresolved trauma but there's peace and love and a willingness to learn and change which allows for growth (and a fluffy ending for bingqui)
Tianglang-jun had also been experimented on but was powerful enough that vault-tec locked him in the deepest levels of a vault after he fell in love with and impregnated one of their top scientists su xiyan, he remains here until shen yuan and zhuzhi-lang break into the long since abandoned vault and free him. He's still incredibly powerful but following his beloved dying and being locked underground for absolutely ages he decides to live a life of luxury in diamond city doing whatever he pleases.
The mutated children (Luo binghe, mobei-jun and sha hualing) have greatly decreased aging, radiation resistance, almost superhuman strength and durability as well as increased senses and an immunity to poisons but they can also control ghouls, particularly feral ghouls but they can influence cognitive ghouls as well, binghe is still the strongest with tianglang-jun but MBJ and SH each control part of the commonwealth and advise binghe.
Linguang-jun ran the northern science division which experimented on his own nephew.
Liu qingge is with the minutemen as I feel while he enjoys fighting he would also really enjoy protecting those who cannot protect themselves as well as fighting to protect freedom and teaching others.
Also I mainly focused on bingqui BC I love moshang and huaming (hualing/mingyan) but I know they're not everyone's cup of tea so I left them in there but ambiguous.
The institution - huan hua palace
Cang qiong + cultivation sects- vault tech
Demon realm -brotherhood of steel+ghouls
I wrote this all out before and it was like 10x better but Tumblr deleted my draft and I had to try and rewrite is from memory late at night so if anyone wants more info or details feel free to ask!
