Dao Seeker - Vol 1 Chapter 2
When all of the asura when to war with the titan race, hell was left empty with nobody there except the wicked soul. Wicked soul was the soul of those who died with many bad deed and because of this the wicked soul in hell was limitless as their number never decreased even after being hunted and consumed by the asura, at the same the wicked soul was different from normal soul in which they are robed of their intelligence and desire by the karma of their bad deed making them lower than common beast.
As the war between the asura and titan raged on coupled with the fact that there was no predator in hell for the wicked soul, their number grew to the point it almost make hell full of wicked soul. As the wicked soul number grow an anomaly happened as one wicked soul started to consume the other wicked soul, this wicked soul started to hunt and consume the other wicked soul to the point it evolved into another being, a being that was neither a soul nor a living being.
Even after the wicked soul evolve into another being it still hunted and consumed another wicked soul and at the same time as the being consumed more and more wicked soul it gained an enlightment into a new dao, after gained an enlightment into the new dao the being started to gain intelligence.
After gaining intelligence the being searched for a way to make his hunt of the wicked soul easier and not long after that the being already hunted half of the wicked soul in hell and because of that the being evolved again and again to the point it gained an innate dao, the being dao was the dao of yin.
As the being evolved more it also gained other innate dao, one day the being stopped evolving and now the being have a corporeal body and many innate dao such as the dao of death, dao of evil, dao of decay, dao of possesion, and dao of darkness coupled with the dao of yin and the new dao that he gained insight the being have seven dao.
A few day after the being have a corporeal body of it own a crack appeared in hell and from the crack a human male appeared, the being sensing the arrival of human male feel curious before it started to want to consume the human male, because of it glutonny the being attacked the human male and in the end the being was split into two by the human male.
The human male split the being into two part, it split the being body and it soul after that the human male sealed the being soul into the depth of hell before he left.
When the being soul was sealed into the depth of hell it gained a new insight but somehow the new dao it gained clashed with the first dao it have and because of the being sealed state it almost died when the two dao clashed and in the end the being sent the new dao into it corporeal body but it was meet with trouble because the being gained the new dao after leaving it corporeal body so there was no connection that can make the transfer of the new dao to be impossible, in the end the being sacrificed one of it dao the dao of evil it gained with it soul was still inside it corporeal body.
After sacrificing it dao the being somehow fused itself with the first dao it gained insight and reached the realm similar to the god, buddha, and the human male that split the being, at the same time the being corporeal body also make a breakthrough into the realm because when the two dao that was transfered by it soul into it corporeal body somehow fused midway and when it reached the corporeal body it make the corporeal body to breakthrough.
The being soul later on will be known as hungry ghost and the new dao that it first gained insight was known as the starvation dao while the being corporeal body later will be known as devil and the dao that was transfered into the corporeal body that the being soul gained when it was sealed later will be named as hell dao.
