Wondering how he should use it to increase the rate of healing and regeneration of his body, Azrael's senses felt a weird warmth coming from just near his diaphragm, right in his solar plexus, this peculiar warmth seemingly wanting to go somewhere, hence why he instinctively guided it all the way to the stump where he cut his arms, the warm current settling there and finally beginning to circulate, going back and forth from his solar plexus all the way to the damaged area.
While this process appears to be quite long and boring to observe or witness, the actual time it takes for the Immortal Energy to completely restore his body doesn't even reach a second, just a moment is all that it takes for his entire arm to completely regenerate, and not a single error or peculiar feeling did he felt after this out of this world rate of regeneration.
Looking at the guide once again, however, he can see the reason why it managed to regenerate that fast, making him understand that there are still some limitations to how much he can use the Immortal Energy in a fight.
Immortal Energy: 97/100 (Recovers 1 point every 1 minute, recovery rate will increase with the possessor's increase in overall power)
'Still, this is already a great result' knowing not to be too greedy, Azrael thought to himself as he felt like this absurd rate of regeneration is already more than enough as it can easily allow him to jump and snap back to a perfect condition state instead of taking an extremely long time to recover completely, in addition to that the fact that Immortal Energy recovers a point every minute means that he can last far longer fighting in the battlefield than he ever did before.
'My ability and strength right now is heavily tilted on battle of attrition anyways, this only improves that even more' he thought to himself as he couldn't help but feel like his path is similar to a meat shield, the only difference between such things and him being the fact that other than him being capable of soaking up a massive amount of damage, he has considerable, if not pretty strong combat capabilities as well, making him a real threat to anyone in the battlefield.
'Hopefully, something in the second floor can help me increase my offensive capabilities, my defenses are already more than enough' the young man added to himself, these thoughts something that everyone will agree with as there's nothing better than his defenses, after all, just the Absolute Regeneration alone makes him undying even if he's not indestructible, combined with that the explosive increase of healing brought about by the Immortal Energy practically makes him immortal and indestructible until his Immortal Energy runs out.
"Let's head to the Ascension Platform now…" after testing both Absolute Regeneration and Immortal Energy, the young man starts cleaning up and disposing the severed arm properly, making sure that it won't cause any sort of trouble to whoever it is that is going to use this humble abode of him next, taking his time to clean up a bit and also dispose of the dishes that he decided he will no longer wash, taking just one good luck at this decade long residence of him before smiling as he nods in satisfaction.
"I'll be leaving now, I guess I won't return here anymore~" he said joyfully contrary to the slightly regretful tone of his voice the last time he left, the only thing he brought with him the bag that he used to carry his equipment and potions, filling them his clothes and some important things rather than tools for exploration, him wearing the already tattered leather tunic and boots, and on his waist hanging the scabbard of his old sword still refusing to shatter even after all the wear and tear it experienced.
Closing the door of this little apartment one final time, he heaves a sigh of relief as he thought that he would finally, truly start his journey in the Ethereal Tower, not even thinking about the fact that it might be quite possible for him to get stuck in the second floor for long once again, given that it isn't all too improbable for the greatest treasure of the next floor to be guarded by such powerful monster once again.
'Let's not think about it that way, bad thoughts go away…' as the thought surfaces in his mind, Azrael couldn't help but shiver in nervousness, urging him to once again make himself believe that the guardian of the first floor's greatest treasure is merely some sort of joke, and while it might still be harder than anything, the succeeding floors are going to be way easier than the guardian fo the first floor.
As he further cements this belief by praying to whoever divine or exalted being it is that can hear him, the young man adeptly moves and weaves across the mass number of people going in and out of the establishments near the road, said road packed with a lot of people about to come out of the Crimson Red City in order to hunt monsters and improve their strength, them moving in a single direction making it hard for people similar to Azrael, moving against them, to move forward.
Of course, that is only for the others as the young man easily navigates between he people moving towards the opposite direction, his height, significantly better than normal, allowing him to see quite a lot and giving him a better chance in navigating this crowd.
Finally reaching his destination, the young man got off the sidewalk and immediately entered a door to a shop, the shop owner wasn't even surprised as she knew that this young man was definitely arriving here at these hours, as this is the usual time that he goes out to hunt.
Expecting that he will order the usual, some ointment, beast attracting and repelling powders and healing potion, the shop owner is already preparing those things when she heard a news that will shock her quite a bit.
"Aunty Eri, I'm going to ascend to the second floor now"
