I got reincarnated and got mistaken as a genius.

Chapter 02 - Discrepancy in History

Hello, it's me again, Kouki.

Well well, so much happened since then, and now I'm 15.

What? Too much time skip?

Nah, it's nothing compared to something else I've found. So, since I've been able to move around by myself at 5, I've been collecting information for 10 years now. Don't get so surprised now, first thing first, currently I'm here in the 3rd planet of the solar system, earth. The current timestamp is...
January 4th, 2102, 10:59 A.M.

I was reborn around 90 years in the future of my previous life. Although it's in the future, it's not like there are flying cars, nor things like teleportation technology. What we have now is military power-suits (when I first saw it on TV, I got so excited and asked my mom, "Mom, is that a robot? Is that a robot?") and a personal laser weapon that's just barely portable.

I think it was when I was around 3 years old, when a thought suddenly occurred to me. How could the human civilization progressed so much in a mere 90 years? The world era I lived in previously, year 2010 to be exact, the progress of civilization has more or less getting stagnant. There was even a scientist group declaring that civilization will slowly wither away as time goes by. So when mom took me to the library when she was searching for a picture book, I sneaked away looking around for history books. Later Mom found me out, but it seems like she thought I was only interested in the pictures. After that, she would upload lots of scenery or beautiful castles e-books to my personal device. As expected from my mother, such kindness! Even though I don't really need those for now...

Should we go to the details, we can go all the way back to the middle age, but I'll explain some points that are definitely different from the world I lived in before.

In 1935, the 2nd World War breaks out. It started 4 years earlier than the history I knew and only lasted for a year and a half. The reason was because America, Russia, and Deutsch has finished developing nuclear weapon at around the same time. Japan launched the attack on Pearl Harbor and occupied Hawaii, but after that Japan was locked on by the nuclear bomber from Aleutian Islands. That was actually Japan's defeat, but America's main objective was only for Japan to totally retreat from Hawaii, hence America never steps its foot on Japan. The Japan disarmament and constitution was established, but the surrender of Japan never happened, so as the result, Japan still retains power over its own country and countless lives were spared. Of course, the nuclear attack on Japan never happened too. The whole world avoided going into a prolonging war with no clear winner, all that's left is the political power and productivity that was used for technology advancement.

In 1950, Apollo 3 successfully landed on the moon, which is 20 years earlier than the history I know. And by the way, by 1948, around 70% of commercial flights are already using jet fuel.

In 1951[1] there was the Cuban Missile Crisis, it's same as the history that I know. America and Russia was about to engage to the nuclear war at any moments, but the passing of pope of Rome at that time have an adverse effect on the whole world, causing the war weariness to peak, which prevented the impending all-out war.

In 1970, World Conference of Strategic Arms Control[2] took place. This didn't happen at all in the history that I know. Learning from the Cuban Missile Crisis, every nation possessing nuclears (which includes Japan), was enforced a possession cap. All the nations possessing nuclear warheads, are limited to 23 warheads.

In 1976, The Europe Tragedy[3]. This is also different from the history that I know. A contagious disease that started in a remote countryside in Europe, spread the terror around the whole world. At the start of the pandemic event, the world population was 9,100 million, but by the time WHO announced the cure, the world population was already drastically reduced to 4,700 million.
