Re-birth
It all begins with the death of Kai, once known as the most brilliant mind ever born but now after death will be in the history books be known as the harbor of death as he created a virus which resulted in the death of 3/4 of the human population around the globe.
As kai in his silver-colored soul form pass through the bridge of the afterlife suddenly gets sucked into space which appeared out of nowhere. Kai found himself standing in front of a giant white ball of light which radiated for miles and miles covering everything which exists or will ever exist.
Ball: I'm what you humans describe as god and also what is known as the devil. Tell me, Human, Why kill all those people?
Kai: Greetings Supreme being, aren't you omnipotent you must already know the reason right?
God: Hm... It seems you don't regret it huh?
Kai: Why would I regret it? I will be remembered, feared, known and respected throughout the Human civilization like you. People worship you cause they fear you, Fear about what you will do if they stop praying
God: I thought you were intelligent but I see now that you are just a coward, Boy I can read your mind I know you did this to protect them from themselves, your contributions for your civilizations will be remembered even by the lesser god Gaea for she is the mother of your race.
Kai: Supreme lord, I would like to ask what am I doing here?
God: Like I said Gaea request for you to be given a second chance in the world for your karma and I also agree with her So I will give you the opportunity to be reincarnated in another world, and no You will not get a system or anything like that, With the power of your karma I will connect your wishes with the Gaea by which you achieve your dream of knowledge.
Kai: I thank the supreme being and Gaea. Lord, will I get any choices?
God: You can wish 2 things, First, the world you wish to be birth in, the time and as whom you wish to be birth as. Secondly, in each world you go after your first world you can have one power thing with you. You can't take people or any living being as it would violate the world law of that world. You will be birth in the mortal world first and you can go to other worlds.
Kai: Lord who will guide me to another world?
God: For that, I will give you a travel pass which will remain in your soul and only come into being when you have reached the top of your world.
Kai: Will I be issued missions or anything like that?
God: That will depend on the lesser god of each world, some gods only control one world like your Gaea she had the power to rule multiple worlds but chose to focus on one earth thus making your earth the center of reality and thus the ability to human to peek into other worlds and write stories about it.
Kai: Lord can you tell me about the worlds which exist?
God: Worlds are stories you have read like Harry potter mangas as in naruto and bleach novel as in Emperor domination, Martial World and many more.
Kai: Lord Can I retravel to the previous worlds?
God: Good question, Yes you can but once you have selected an idea you want to take from that world you can't take anything else.
Kai: Lord If I were to reincarnate in some world as the protagonist who has the system then what would happen?
God: Systems exist with the blessing of the gods so you would have to seek the blessing of that world's god.
Kai: Will I be reborn as a baby every time?
God: When you want, who you want to and at what time are your choices, you can choose to be born as a baby or anytime during their life?
Kai: What if they die moments after I transfer to their body
God: You will lear this trivial thing as you go on.
Kai: Thank you for the opportunity lord. I would like to request and you kindly send my regards to the mother of Human race Gaea for me too.
God: Good, Which world would you like to go first?
Kai: You said to start with the Moral world so I would Like to start with Sword Art Online. The time of 7 years before the birth of the protagonist Kirito, the location is to be born in one of the wealthiest families.
God: Good choice, You can learn a lot during the arc.
Kai: Lord I would like to ask if there is anyone else who would also be given the chance to reincarnate?
God: Sometimes Lesser gods reincarnate people but don't worry I have changed your soul to be stronger then their so if you want you can take over their bodies too.
Kai: Thank you, Lord, Will I carry my knowledge with me through my journey?
God: That Is the reason you're going on the journey, to understand and expand your knowledge thus It will be bound to your soul, you will carry all the knowledge you acquire. And each time you select some time to carry to the next world it will marge with your soul thus making it a part of you.
Kai: Thank you, Lord, I'm ready.
God weaved his hand and space cracked and consumed the Kai.
