There are many gods in the universe, some more powerful than others, Gods of belief or occupations, Gods of stars or planets, Gods of Emotions, Gods are everywhere born out of human beliefs, so long as they are not forgotten they are Gods, those who are forgotten are banished and sent to many different places, either they become a human who has lost their divine power, or they are sent to the underworld to rot in divine seals, cursed to rot for eternity.
Shinshi the God of Power was not made as per normal gods, of course, no god knows how their body manifested but know that the belief of humans gave them mind and power they somehow were given a body, even the smartest, the all-knowing Athena could not figure out how they manifested a body.
Shinshi knew the day he was brought into this Universe, he knew the secrets all gods wanted to know, but they didn't deserve to know, not after they sealed his power when he was first made, when gods are made they do not wake for 2 weeks, 14 years in Human time, that was enough for the elder gods to seal of over 90% of Shinshi's power, their reason is so "he doesn't create an imbalance in the world" but the true reason is that they wanted to remain supreme, remain in their powerful spot as an elder god.
Of course, they thought their plan had succeeded, it did but they didn't think of the possibility of the powers Shinshi possesses, being the God of Power makes it possible to copy a god's divine power, or any power to be exact, gods can read the minds of any lesser being, but no god has been able to read another gods mind, but Shinshi can, his god powers have been enhanced due to being the God of Power, not to mention his intelligence, the only one to rival him is Athena the smartest god in History.
But things do not go well in the next year or 365 human years, he soon is considered a traitor and is being sentenced to Banishment.
"Shinshi God of Power, as you know getting directly involved with mortal affairs is considered treason, your Punishment is Banishment, you are to become a Human and lose your divine power, have you anything to say," the Elder god said, Shinshi who has been kneeling and tied with divine chains that block a god's divine power.
'what happened, why am I here in this moment, about to lose my divine power about to be banished' Shinshi thought, 'oh that's right it was 2 weeks ago when it all started.
/2 weeks ago or 14 years ago/
Earth 2024, was just a normal day, wars, killing, love, it all changed in a heartbeat, weird portals started appearing all around the world, humans didn't know what to think of these "gates" as they called it, they sent military personnel to investigate the portal, but they never returned.
A few days after the failed mission to investigate and gaining no information on what these gates are beasts started showing up, humans called them, Monsters, ravage beasts using something unknown to them, summoning fire or ice, having super strength. around this time Humans started gaining abilities as well, humans finally being exposed to mana through these creatures triggered their own to show up, humans could finally manipulate the mana inside their own body.
but it wasn't enough, humans weren't strong enough to fight these creatures, to protect their world and protect their race, Shinshi was shocked to see the amount of willpower and will to live by these humans, any other race may have given up but they haven't.
Shinshi searched through human history hoping to find something useful for this generation of humans, he stumbled upon Video Games, he found out that for entertainment humans would lay games they had created, these games ranged from killing to magic, he found it odd that humans thought of magic but couldn't manipulate it all this time.
Soon he found something the humans called "System", something that would help them in video games, make them stronger faster and keep track of how powerful they were. Shinshi, being the God of Power, could easily design this, but once he did and gave It to the humans, he knew he would be banished, but Shinshi was fine with this, he already had a plan.
he started by getting the foundations started on this system, making sure only the user could see their screen and no one else's, once Shinshi had finished this it was time to design what is in the system.
He started with the most important part, being able to add "skill points" to either physical attributes or spiritual ones, Strength, Agility, Vitality, Sense, and Intelligence, all these play an important part in the System, next was the Humans information such as name, age, height, and the System number they got, then humans could tell if they were on of the first ones to gain a system or not, then was the level the human was at and how many skill points you would get per level, then there were titles, sometimes you would gain a title on different things you would do in your life, whether it be washing dishes or killing monsters, it would give you buffs in certain aspects of your skills.
Then there were quests, there would be automatically generated quests related to everyday life or killing monsters, this would give them many different rewards, whether it be gold, a special currency unique to the system, experience to level up, or special weapons or titles, quests are what allow you to progress in the system.
then there is the Shop, the currency used in the shop is gold, a currency only in the system and can only be used to buy stuff from the shop, from this shop you can buy weapons, armor, shields, potions to recover health and mana, potions to gain special buffs, or special items able to give you a small pocket dimension to store different items in, in case your system inventory is full.
Inventory, this is a small pocket dimension every person with a system gets, it allows you to store any item, but there is a random size of inventory everyone gets, could be large, could be very small.
then there is the equipment tab, where you can put on the armor you have bought from the shop on your body, you can either have it invisible or show it off, this also allows you to equip weapons that you can summon from your inventory at any time.
the last tab of the system, trading allows you to trade with anyone you have met, you can trade anything that is inside the system, weapons, armor, all sorts of items can be given to others, as well as gold.
"Finally I'm done, time to give this to the Humans," Shinshi said, as he swiped left and sent the system to people all over the world, soon 1 in 10 people gained a system, but it also has a message.
[you have received a gift from Shinshi the God of Power, you do not have a choice to accept or decline, when this message is over there will be a tutorial to show you have the system works and how to navigate it.]
all over the world, 800 million individuals got this message, soon after this happened the Humans could finally have a fighting chance, meanwhile, Shinshi was being detained.
/Present/
'well I guess it is time to start my plan' Shinshi thought.
