More modern times?

Okay, I admit I went a little crazy these last 47,000 years but I'm getting really really close to a more civilized time.

First, my civilization expanded rapidly then collapsed because of some really bad natural disasters that everyone blamed me for because I'm supposed to be god they tried to kill me so I killed them in return. I took every book and piece of paper with written history on them and tossed it into my inventory for preservation after making copies in case anyone was interested. I then went into the mountains and slept for a really long time like 20k years so when I came out I found that even if we collapsed a lot of my teaching didn't get abandoned so Japan is pretty advanced compared to the rest of the world in -30,000 BC.

It also seems that I became a bit of a mythical figure as in all the stories about me revolve around me being a god Emporer that upon losing his wife destroyed his kingdom in his sadness with natural disasters. They also changed my name and I don't know if I'm cool with that or not. Anyways it seems like I've been mostly forgotten and my Descendents spread throughout the land as there are usually people that seem to have stronger bodies that live longer than everyone else with black hair and blue eyes that almost look unnatural.

I actually just decided to take it slow this time and live amongst the people while getting as many copies of written history I can find. That continued for about another 26,000 years and I left quite the number of Descendents and bodies where I traveled wooing women and slaying evil eventually getting yet another legend as the first shinigami for those who commit wicked deeds saying that a man wearing formal black and white shihakusho (it was actually a white T-shirt and a black long cardigan but whatever) that will come bearing twin swords to claim your life. I've also continued to spread advancements that improved the quality of life again increasing the advancement of Japan but at a more subdued pace.

It was actually at the year -4,000 BC (that would have been 47,000 in the Japanese calendar if my people didn't throw it out) that I decided to try again creating my own little empire starting in what would one day be Tokyo. Gathering a bunch of people that were looking to start somewhere new again along with as many of my Descendents (since apparently, I have really good genes that persist as the dominant gene even after all this time) that I could get to come along and set out to settle the land.

First I chose a good place to begin and got to work once again teaching the people what they need to know and getting established as the top authority before I alone went out and subjugated the other groups nearby and strong-armed them into seeing me as the top dog in this region. Once again time skipping a couple of hundred years I'm once again the King with everyone answering to me but this time I've done two things differently. First was the creation of a democratic western type of government that I'm not a part of as I want them to handle the way we are run but I'm no figurehead either I can go in and strong-arm them if I have to if they do something dumb. Since I'm not directly running the government this time I'm seen as something more as an immortal protector of the land fighting off the phantasmal beast and any invading parties that the established army can't handle.

The second thing I changed was the schools I've spent a lot of points gathering every modern book I can then place them inside what has been dubbed the library of Heaven. Third is that with the library I've also taken to getting apprentices and my descendants have a stronger chance of getting in (whether they know they are from me or not) to learn both swordsmanship and magecraft of the modern times (since I've never learned age of gods magecraft and I don't think it even technically exist yet.) while encouraging them to learn more but exercise caution as it is dangerous and you could die. I've also made it to magecraft is no secret so mages usually wear a blue or black band either on the arms or head to show their status.

With all these changes and the spreading of knowledge, I've once again reaffirmed my position in the land of Japan declaring myself as Uchiha, Hideo. So over the span of 1,000 years with lots of scholars visiting the library we established ourselves as the greatest power in Japan and proceeded to conquer all of Japan bringing it under one rule while experiencing a sort of renaissance as every piece of knowledge I've put out there spread allowing the people to grow, expand, and prosper.

It was also during this time that I finally remembered that this is the DC and Fate crossover universe meaning that gods very much exist. One such example is the fact that Tamamo no Mae is my wife thank the sun goddess for that. So now that it is -3,000 BC I've got like maybe another 1,500 years before Japan is literally a superpower in the world with cellphones and guns. Sure the age of gods may rule with mystery over physics but that doesn't mean physics doesn't exist it is just overshadowed by the power of mystery and if the world has to choose between the two then it will pick mystery. The same way that mystery is treated in the age of man in the canon of Fate but considering this is a crossover with DC then the age of gods should never end what with the fact that the greeks still exist.
