The initial plan was for him to return to the Real World with the son of the hero, but that wasn't possible because the hero intervention, he was then forced to throw the boy and his journal first and wait for a chance to catch up with them after that .
Even though the Hero lost a considerable amount of his original strength, he from time to time was bursting with enough power to severely injure the already severely injured demon, what made matter worse was the fact that due to some miscalculation on the demon part, the portal closed the moment, the child crossed .
Leaving the now Elemental hero losing all of his sanity and feverishly attack the demon, uncaring for how much injuries will he get from doing something so reckless, the weeping voice of the boy's mother acted as a fuel to the already raging Hero, making his attack even more stronger too, he was beginning to overwhelm the demon, but then it happened, the Elemental Hero lost all of his consciousness and humanity and began to randomly attack each and everyone in his line of sight, not focusing only on the demon, anymore .
He was massacring his own troops and was even going to kill his wife, but suddenly something in him awakened and he directly left the place with his wife in hand and escaped from the scene, news about the King Hiro were never heard since that day .
The demon himself fell not long after, he succumbed to his injuries and died after massacring all the humans of the said kingdom, he tried to locate the whereabouts of the Hero, but to no avail, wherever he was hiding in, the place was quite effective in hiding him without any much of a problem, he wanted no one to know about what happened in here, so he began to aimlessly massacre everyone that decided to come close to the rapture, much to his dismay, the amount of blood he still had were all evaporated in the intense battle with the Hero, leaving him strapped here, injured and waiting for death .
The Wicked Forest was where the rapture appeared, in the demon last days of living, he made sure to turn that land into a huge red zone that should be avoided by anyone passing through and at any cost .
The journal was a magical artifact, one of the few Divine artifacts that are to this day scarce in numbers, it kept recording what was its user was thinking, even though the distance between the two was quite huge, it didn't stop writing everything that happened until the very end of its user's life .
The Demon was my ancestor, he also wrote down the technique he used to refine the blood of the hero's son and talk a lot about how precious would it be to get our Demon race hand on that Shard, that was what enticed our demon race to come to this land, the other thing that enticed us about this land was the fact that my demon ancestor mentioned an item that was quite being sought after back in the Real World at that time, Mana Stones mines, something that allow my ancestor to increase his strength and become a Ruler, if not for the fact that his spirit have already been torned due to the use of a secret technique to escape getting completely obliterated by the assault of the Shard, he might have been able to found another way back and become a strong powerhouse for us demons in the Real World, pity .
The first one in our family, but not the last, he was also the second figure of that realm of strength in the entire demon race, he also mentioned that a huge amount of those stones lay in this land, if you used a huge enough amount, you can even use it to heal your injuries, this effect was quite costly but its healing effect was even better than the healing nectar found back in the Real World, he also mentioned different herbs and ores that could benefit our demon race and elevate his ranking in strength greatly, so knowing about all of this most of the other Demons become interested to reach this place, thinking of all the riches, they might be able to find .
Most of the demons at that time wasn't even a little bit interested in the so-called Shard, we were more focused on collecting and gaining those said resources, but a big problem arose, one that almost made the unity of the demon race crumble .
The journal of my ancestor was found by the Current Demon Emperor, together with the unconscious and barley hanging to life son of the Hero, he was finding it difficult to breathe in the new atmosphere, but he was brought back and got accustomed to the dense Mana in the atmosphere .
After they made sure that he was fine, they tried to send a few scouts to the other side, but they met was one problem, the effectiveness of the Hero's son blood on opening the portal to the other side, was many times lower than what my ancestor in journal seemed to believe .
But after a few experiments, the demons found that the blood essence extracted from the heart seemed to be of noticable quality, at least enough to allow two people to go to the other side and come back, but the amount needed will leave that guy need to recuperate for quite some time before able to produce the same amount of blood, the demon found out that even with the use of some precious herbs and medicine, it would still take that little guy a few years to recuperate the lost blood essence, meaning that every campaign sent will be a huge gamble on the demon race, but both of those problems were solved by the suggestions of the Demon Emperor .
The first existential crisis that threatened the unity and stability of the demon race came knocking on the door, who would be the two that will be sent to the other world and how long will that human need to recuperate before being able to provide the others with the same chance, how much can two person benefit the demon race .
The shrewd mind of the demon emperor, who wasn't even a Duke came to lead the road, he devised a way that could allow us demons to see whether was coming to this land was really worth it or not, what made him eligible to give his opinion about matters like this at that point of time, was the fact that he was born with a special ability related to space, something to this day i wasn't able to gather much information about, but anyway, the other Demons decided that they were going to compete over the two quotas which will allow two chosen people to come to this land, as per to the suggestion of the current Demon Emperor .
Luckily for our family, we already got one of the two quotas without having to compete with others, the other quota which was being competed over by the demons ended up going to the current Demon emperor hands, but he suggested something to maximize the profit of this journey to the demon race, he suggested that they all should fund this mission by buying a more suitable spatial storing equipment and that the more the merrier, every demon began to give all the money he can, but they were still demons .
So everyone share of the expected loot was to be distributed according to how much money they donated to fund this campaign, some accepted this wholeheartedly, but the majority frowned upon such a proposition, sensing that a conflict is bound to arise if things were to be done like this, another suggestion came to be, those who didn't donate much money can still negotiate how much their share of the loot was going to be, on the premise that they forsake their right to battle for the two fixed quotas in the future, a proper exchange of benefits that left all parties content .
The whole operation was deemed to be completely secretive, others than the two with quotas and the only Ruler powerhouse to keep checking on them from a far, no one else was allowed to even be seen in the vicinity, if someone was to be seen breaking the rules, he will be delt with directly and without any mercy .
Once the equipment needed for this operation was set, the two chosen people entered the Spatial rapture after refining a new two medals made of the blood of the hero's son, the demon who was chosen from my family was my father, when he returned and the families system was introduced, he decided to start his own family and he quickly and steadily gain enough strength to become one of the 10 main families, there was no one sitting above the 10 Grand council at that time and all of that happened thanks to that one trip he made to this land .
12 years later after they came back the Demon Emperor had came to power, with enough strength he forced the other 10 main families to serve under him, but his actions of challenging and killing those who were close to become Emperors as well, left quite the deep resentment towards him in the hearts of his followers, but no one is able to make him step down from the throne.
He didn't rule with his fist alone, no he used his wits to gain the respect of all the demons, after all he came with the initial plan that had us achieve what we achieved today, so even though he was resented by most of the main families, there were still a few families that are willing to go with him in the lead through stones and fire .
My father told me throughly about the experience they had in that campaign, but the most precious thing he said they gained through this campaign, wasn't the huge numbers of Mana Stones they returned, no, it was information, he was mainly responsible for collecting Mana Stones and locating the mines, the current Demon Emperor was the one responsible for the collection of herbs and information .
They spent a 10 month period in this land, they made contact with the forces that have allied with my ancestor before and was given most of the information that they were going to need going further, most of the information they gave them was already mentioned in the journal, but they mentioned also the information about the place where they buried my ancestor, they were completely wiped out soon after, due to the state my father and his demon partner found my ancestor in .
Those guys who once swore fealty to my ancestor, exploited the fact that he finally died and looted his body, but he already expected as much and told much about his accumulated wealth in his journal sometime before he died, then when those allies of his were asked about the whereabouts of his wealth, they completely denied knowing anything about it and so they were wiped out as a result, the belongings of my ancestor were put in a spatial pouch, those who didn't have a basic understanding to how it worked, could only dream about getting what was inside .
The pouch had a detailed map of the land and where were the location of the resources, there were a few red zones marked as dangerous by my ancestor, which baffled the two a bit, thinking what could possibly be considered a threat to a Ruler rank demon, but they discussed that it was better for them to finish what they came here for without any need to risk their lives going to these marked area .
Seeing tat there were a lot of locations to cover, they decided to split up and meet back at the rapture in the night, the first day of them arriving passed in a blink of an eye and the same went for the first 8 months, they did their job as scouts perfectly, they looted all the resources they could and filled most of their spatial rings with Mana Stones, ores and other valuable resources, the demon emperor suggested that they stay for an extended period of time and suggested that it might be good to stay here and wait for the next batch to come .
But my father convinced him that if they stayed here, there was no guarantee of what might the other demons back in the Real World think and what might they think of them, their objective was to come and prove that coming to this land was worth it for the demon race, if they delayed much, conflicts are bound to arise, not to mention they already filled most of the spatial storing equipment that came with them, so there really no need for them to wait for a few years in this place, the concentration of Mana was very bad for increasing their strength, if not for them using Mana Stones to train, their strength might have regressed instead of progressing .
They were both Dukes now, the demon emperor was still a little bit short of reaching the Ruler level, my father was catching up with him, both were a little bit short of reaching the Ruler level, but that little bit short would take them at least a decade to reach and that was only possible because the huge resources they will be getting thanks to this campaign, otherwise it might have taken both of them at least a century at most and half a century in the best case scenario .
The Demon Emperor wasn't convinced, but he wasn't able to refute the reasons given by my father, so he suggested that they at least stay here for at least a year, my father seeing no issues with that he agreed with his suggestion, it would allow them to gain a bit more resources and they might be able to finally fill the storing equipment in their hands completely .
But something happened that forced them to change that plan of theirs, a demon king was born, their first reaction was to laugh at that piece of information, wondering who in this backward world would be so arrogant to identify himself as the king of all demons, but then they saw the destruction he kept leaving behind and instantly understood that it wasn't an identity but at most a title given to him in consideration of the havock he was creating alone his path .
After they saw how much strength he had, they both lost interest in him, my father asked whether will it be okey if he decided to teach him a lesson, normally his companion wouldn't have had any complaints if he did, but this time things were completely different, not only he didn't agree to him doing so, but he even wanted them to go and join the ranks of the said demon king .
My father tried to understand the logic behind such a move on his own, but wasn't able to, so he asked his companion to explain the need to do such a thing and his companion replied saying that he wanted them to join the ranks, so that they become able to understand the interior of that demon king army and that they might even get a chance to gain classified information .
But my dad didn't believe that to be his actual motives, but he still acknowledge his point of view, but he still didn't want to join in the ranks of that demon king, someone who was much weaker than my father, but the demon emperor had no such complaints, so he sked my dad to do his own part, while he go and join the demon king army, my dad seeing no problem with this arrangement, he agreed to carry on doing both of that guy's work with his, but asked the demon emperor to compensate him once they go back, after the two of them came to an agreement, they parted ways once again, but this time they agreed to meet when it was finally the time to leave this land, with that agreement both went into doing his own thing .
That man and my my dad was once considered each other comrades, at least that was the case with my dad, he also once told me about that demon king, he said that his origin was one of mystery, but he also told me his evaluation of him, he said that he was the most ambitious demon he had ever seen and till this day he didn't understand how was he able to reach the Emperor realm in that short period of time .
But anyway, after they parted, my dad kept going around collecting resources for both of them, he kept hearing about the deeds of his comrade echoing through the land, he was even able to become the second in command under the demon king and was even given the title Hand of darkness .
Before the end of the nine month, he suddenly appeared in front of my father and asked him whether was he ready to go back or not, my father told him that he was ready whenever he was and the demon emperor told him that he too was ready and wanted to go back, my father tried to ask him about what happened to him and what made him change his mind, but he was restless and only told my father that he have gotten a few pieces of information that he must go back and report them back to the elders in the real world, seeing him like this my father didn't say much and only tossed him the Spatial Equipment, he should have been responsible for and began gather his things and they both became ready to depart, they used the blood medal stored in the equipment in their hands and tossed it in rapture .
The moment they began to move a terrifying aura locked on their location and they hurriedly without even looking back to see what it was heading towards them, they squeezed directly into the rapture, but more weird things happened to them the moment they passed through, my father was fine, but the demon emperor clutched his head suddenly and began screaming on top of his lungs, saying they are back , the heroes are back .
