The training with Debauchery in the following 4 weeks focused on getting Yunan to spam all his spells and techniques, until he ran out of mana, rest for a bit then repeat the process, Debauchery did not have much left to teach Yunan, so they decided to focus on his abilities as well as his natural mana and stamina regeneration, and the easiest step, is to spend every drop of it, rest half the time needed to be fully restored and repeat into an endless cycle.
Another thing that was to be trained, was dual casting, usually one needs to be at level 20 to duel cast, but that is how the lazy ones worked, anyone who was capable of using mana is capable of multi-casting it just required enough focus and flexible mental acuity. And Debauchery thought teaching Yunan the basics would help him further down the line with dealing with multiple enemies that are smarter than the current ones he is facing.
The spells in focus were icicle and fireball, Yunan was expected to cast those while keeping his grip on his weapons, something that is very challenging in and of itself, but Yunan still managed to cast both while attacking with some accuracy, but not enough to satisfy Debauchery.
After the month ended Debauchery left for the surface world for some business or the other, and Yunan was left alone to fight his way to the 20th floor. As to be expected from a hard worker he kept the cycle of near exhaustion at all times, even sleep time was reduced to keep his body in constant state of regeneration.
however that didn't last for a month before Yunan almost collapsed in the 13 floor while fighting ogres and imps, the stacking debuffs of the imps have brought out most of the stress he kept suppressed with the Queen bee honey and sheer will. So after a particularly nasty fight Yunan decided to return to the 10th floor, and headed straight for a hospital, because his wounds were not healing as well as they should even after the debuffs wore off.
According to the doctor, Yunan's body was over saturated with stress and healing magic and is building an immunity to healing magic, he needed to stay in bed for a week and allow his body to digest all the magic and release the accumulated stress, and Yunan must watch his stress levels and magic saturation, and take at least one day every week to simply rest, otherwise before Yunan's constitution could repair his body he would exhaust his life span.
The doctor also told Yunan he was too lucky that he did not collapse earlier, as some who had accumulated such high amounts of stress in comparison to their constitution would just drop dead most of the time, without having the time to notice slow healing or loss in wisdom, he also told Yunan that he would pay premium price for whatever nutrition Yunan used because that was what saved him.
Yunan did as he was told and went to rest, however he passed by the guild and left a note for his friends. "nanny required" was what the note said, he also sold the useless stuff that the armor have refused to eat, apparently, the armor has a digestion limit to certain items before level up, meaning that if you feed the armor the same thing it would not grow and instead start rejecting the item making it better to accumulate different resources while feeding the armor.
Back in the cabin Yunan filled a hot pool and poured honey in a ratio of 1 to 9, he then told Drogon to keep heating the bath as he slept inside it, he propped his head and relaxed himself in the viscous bath, and slept soundly for the first time in a month.
When Yunan woke up, he found Reina pulling him out of a very dirty bath water, it was not the burnt honey, because the smell did not change, only the dirty, grey and black color was what changed, looking closely it looked like Yunan has shed his skin and changed his blood. Yunan still had open wounds when he got into the bath, and his skin was felt dry and itchy, however the wounds were fully healed without scarring, and the uncomfortable feeling was gone.
"How long did you sleep in there?" Reina reprimanded Yunan as she helped him up and into the bedroom, although Yunan was rested, he had very bad control over his body, he still felt tired and groggy. "The day i sent the note, how long ago was that?" Yunan answered as they both lay down on the bed. "Two days, are you getting stupid or something? Stop trying to get killed, I still need a harem to accept me when get older".
Yunan slept soon after drinking a mouthful of honey, it was a pleasant sleep, with warm and soft dreams, when he woke up, the first thing he did was call out to Reina, only to be answered by two cat eared girls with maid outfits, who had been hired by Reina to serve him until his body fully recovered, Yunan simply let them do their job and stayed in bed for longer.
The girls were very eager to serve, bringing all sorts of delicacies during meals and providing endless muscles therapy as he lay on bed, even in sleep they would warm his bed and make sure he slept as comfortable as possible. Although that did earn him a few punches from Lili who barged into the bedroom late at night because she thought he was badly injured when she read the note, however when she found him sleeping in comfort, she was angry at her wasted worry.
However she did send away the cat girls and replaced them herself, according to her, only they had the right to sleep with each other so comfortably, and if he wanted to play with girls he should never do it home, and he should find a place where she could never find otherwise he was going to get beaten up alot, Yunan only smiled and nodded his head as he immersed himself in the supple feeling and warmth she gave off as she embraced him.
