Yunan found he was mistaken about the divinity of dreams he just got, it was really beyond his imagination that what looked like a dying divinity was actually complete, it was full of power and the dying feeling he got at first must have been the death wishes of the old man.
Extracting the divinity was easier with the help of the old man, and maybe thanks to his help as well it did not try to help Yunan ascend like the others and did not need as much of a suppression, maybe all complete divinities were sensitive to the will of their master unlike the shards that sought to hurriedly help their master ascend. Once the divinity was claimed and stored within the sea of consciousness it started to manipulate the spiritual energy inside the cave and caused it all to gather at the tip of Yunan's fingers.
The pressure of that huge amount of spiritual energy almost turned Yunan into a dimwit, but fortunately, the Black Fate intervened by shielding Yunan's mind, thereafter, Yunan made the genie store all the spiritual energy and condense it into liquid in preparation for turning it into stone. He then took the back part of the cave as a whole and placed it inside his own mountain in the back garden, where he made the genie turn the spiritual energy and mould it into a spirit stone that would engulf the cave. The spirit stone that resulted from condensed spiritual energy was about 50 meters thick and by design of the genie, it only enveloped the back room, the rest of the cave was still flooded with spiritual energy even without the stone covering it. After some mild changes, the cave was made into a place where spiritual energy gradually ramped up and culminated in the back room where the energy there was so dense it looked like a fog.
After dealing with the cave, Yunan sent a message to his friends about the cave and warned them not to get inside it too carelessly, given that with or without his warning there is bound to be someone reckless, he chose to let them know so they would be reckless knowingly. As for the treasures, he could not even appraise they were stored in a private room where Balin can spend his time playing with them without the added danger of blinking the whole place out of existence.
Lastly was the fiery golden egg, Yunan was not sure what to do with it and was about to call Hephaestus about it, but the voice of the heart of Tartarus sounded in his mind "drip your blood on it, it will do you both good". Yunan never thought about using the mark of Tartarus to communicate before, he thought it was like a limit breaker and a chain at the same time, so when he heard the message he felt stupid for not realising that the previous notifications he got from the mark were simply messages from the heart of Tartarus itself.
Upon dropping some blood on the egg, it cracked, and from within came out a ball of flame that danced around Yunan before entering his bloodstream through the healing wound. Yunan didn't even get to be surprised before the mind-wrenching pain took over him. No amount of strong mentality can help if the pain went past a certain threshold, and what Yunan was experiencing was his body changing at the cellular level, the pain was the natural outcome of having one's body be destroyed and rebuilt while they still were conscious about it.
Time had ceased to be of meaning for Yunan, he did his best to endure the pain and stay alive, but that bit of conscious thought was also devoured when Drogon seemed to also feel the need to slip inside Yunan's body and mess around inside just like the fiery golden ball did. That shattered Yunan's remaining defence and he blacked out right after, luckily he was home where he could be guarded and tended to by his beloved ones, because the current changes happening to him would be disrupted or even corrupted if the genie used spatial shift or teleport to bring him back, thus the genie just led the girls to the back garden where Yunan had just finished dealing with the new meditation cave and decided it was time to finish his quest.
The first to notice something was wrong was kitty, she could feel the small cut Yunan made by himself and then the excruciating pain also took away her breath, her sisters envied her this link to Yunan even with such a side effect, but none of them wasted any time in cleaning up and protect the vulnerable girl before they returned all together to the private dimension and contacted the genie about the location of Yunan. By this time both the man and his cat were out cold and the girls carried both gently back to the bedroom.
Yunan woke up to the sharp ping of the Tartarus notification system "quest cleared, congratulations on obtaining two mythical bloodlines, new pet gained, all functions of the Black Fate have been unlocked as a reward for clearing the quest before 100 years". Yunan listened well to the announcement and mulled over it for a few moments before opening his eyes and meet those who were anxiously waiting for him.
Turns out other than Kitty and Ophelia the rest has been reassured by Drogon and went on to deal with their work, leaving Kitty to help sense any complications and Ophelia to heal repeatedly replenishing the mana and spiritual energy Yunan lost. Both Kitty and Ophelia were so close to Yunan he could barely breathe while being smothered by softness, it put a smile on his face, but before his hands started wondering where they shouldn't he discovered his newest pet.
Drogon was on his accessory mode, and Sapphira was curled up in a ball on his chest and purring loudly, and beside her was a bird with fine golden red plumage, it looked soft and enchanting, just like flames, the bird had a hooked beak and ruby red eyes, its neck had a feathery mane, it's body was proportioned like that of any bird of prey, large wingspan and sharp talons, the only thing that made this one differ from the birds of prey was the majestic mane and the striking colour that looked like a blaze has taken physical form.
