Once Serina was out of sight and Sven could no longer hear her footsteps he stood up and started to attempt to walk. He would put his good foot forward and fall off balance. As he continued this for hours not giving up finally after what felt like almost 7 hours Sven was able to walk around normally albeit not fast but aleast he was mobile.
'Good, it really is possible to live like this now I guess a little more and I should be good as new' thinking this he layed down on the ground and started doing push-ups untill it felt like his arms where gonna fall off. At which point he would break his arm and heal all his wounds but never activated the stat buff of his ability. He continued his push ups for 3days without realising, it wasn't until Serina came back that he stopped, he was covered in sweat had taken his shirt off revealing his round stomach, he approached her and asked what he needed to do to get stronger.
"Just keep doing what your doing don't stop unless it's for food or water. You will do push-ups all day Monday to Wednesday. And from Thursday to Sunday you will run" she told him handing him a water bottle.
Sven looked at her and frowned "but Ms Serina... I cant run even walking is a bit of a problem" he said shaking his missing left foot.
Serina looked at him and sighed "did i ask about your disability? No, no I did not. I don't want any complaints you will follow the training and I will have someone deliver food to you 3 times a day. I will also drop by from time to time to check up on you and monitor your progress"
Serina then turned to walk away when Sven called out "Ms S what about other training". Without getting a response Sven watched as Serina once again disappeared.
Unsure of what to do or even what day it was Sven just got back to doing his non-stop pushups, after what he felt was almost 6 hours a woman arrived wearing leather light armour that had been dyed black and a hood hiding her face she appeared and placed a tray of food on the bed and disappeared again.
Walking up to the tray Sven noticed there was a note reading it out loud "it is now Thursday commence part two of training....Run fat boy run" after reading the note Sven scrunched it up and threw it into the dark cursing "you fucking bitch I'm not fat im chubby!!!!"
After cursing into air for a few more minutes Sven got up and ate his food before attempting to run. For hours he would fall but he would get back up and try again each time making it further than the last. Finally by Sunday afternoon Sven was able to for the most part run with little to no trouble.
Sven continued this training for 3 months with the only changes being that every 2 weeks Monday to Wednesday training would switch between pushups, squats, crunches and other basic workouts. By the end of the 3 month period Sven had lost almost 15kg and had his large round stomach had gotten thinner and he had muscles forming on his arms.
Once Sven had done this training alone for 3 months Serina decided to start training him in earnest she had rewritten Sven's training schedule Monday to Thursday is hand to hand combat and weapons training Friday to Sunday is ability and magic training.
The training started on a Monday with Serina first teaching Sven the basics of unarmed fighting the process ot watching the opponent's body, shoulders and feet and how doing so will allow to better predict where the opponent is going to strike. While during magic training Serina would use her own mana to guide Sven's around his body expelling it allowing it to increase in size as it regenerates.
After 4moths while Sven sat with Serinas hand on his back he spoke "umm Serina is this mana training really as important and the ability and physical training? After all I don't really use my mana for anything". Turning his head to wait for Serinas response.
"You see with your unique ability any damage done to your body is used to temporarily strengthen and heal your body, most battle mages can do a similar thing with magic but what im aiming at is once your mana levels surpass 200 I can infuse a magic beast core into your body the process will be excruciating and may cause your limbs to break down and fall of but if you keep your ability active you will heal faster than the damage is done" she explained with a face devoid of any emotion.
"Your gonna what to me? No why would I let you do that no way am I gonna allow it, you want me to let myself be experimented on? And for no benefit" Sven retorted moving away from Serin, attempting to put distance between them he turned and ran.
As Sven looked behind him at Serina he noticed she wasn't moving but then as she was almost out of sight she disappeared in a blur and reappeared infornt of him stopping Sven from going any further. She looked down at him and gave a smile.
"I'm sorry to inform you but you don't have a choice, you will have to go through the procedure and also that was the last magic lesson for a while as today you finally reached 210 mana points so you can now handle a mana core implant. And just to let you know for you attempting to run we will chose some of the strongest mana cores we have just to make this process all the more painful for you" Serina whispered into Sven's ear while grabbing him by the neck.
Serina then dragged the screaming and flailing Sven into the dark and once reaching a wall with a dull grey glow she infused her mana into it opening the wall allowing access into a large laboratory filled with tables and glass tunes filled with animal corpses and mana cores glowing inside a display case.
