Strongest Survival by Otome Game’s Heroine (LN) - Vol 3 Chapter 4: Approaching Threat

In the history of geology, more than 500 million years ago, there was a period of the Paleozoic Era known as the Cambrian Period. This period, being the first period of the Paleozoic Era, does not only have a significant meaning for geological research, but also is the most insane, splendid and mysterious period in paleontological history.

Before the Cambrian Period, the Earth’s species were relatively monotonous. When the Cambrian Period started, just after millions of years, which is a relatively short period of time in terms of geology, all kind of species on Earth suddenly evolved wildly. Countless of invertebrates, arthropods, mollusks, brachiopods, annelids etc. have appeared on the planet without any warning, greatly enriching the diversity of the Earth’s species. This million years period is known as the “Cambrian Explosion”. And after billions of evolutionary years, the Earth today blooms with diverse lives.

The cause of the Cambrian Explosion is a huge mystery and also the biggest paradox of Darwin’s theory of evolution.

What if… the Cambrian Period is coming back in this era when human civilization has already conquest the entire planet, and the global species will once again evolve wildly, what kind of challenge will this planet encounter? What kind of fate will humans, who are falling from the top of the food chain, face?

Razé was a cheat soldier at the age of 15, thanks to the memories of her previous life. One day, she was summoned by her superior – the devil Prime Minister and was ordered to go on a long-term solo mission. She was expecting a harsh mission, but…

“I knew you are the right person for this, Lieutenant Colonel Razé Orphan. I want you to attend the Centrior Imperial Magic Academy starting from this spring.”

“…..what?”

Well, it seems that she has been appointed as the “bodyguard” for the prince and other noble’s kids. And so, she was enrolled to the school where the aristocratic-sama gathered.

Although she was puzzled by the glittering school life, she was trying to live a life so as not to be bullied in the future. But it seems there was a secret that she didn’t know hidden in this world.

“Hey!!!!!! No one told me that this is an otome game!!!!!”

As a bodyguard, her life would be over if any of the noble kids got hurt. But then a young lady who claimed to be the ill-fated villainess came by. If the girl died, won’t she be dead too?

Today, Razé will continue to watch over her school life (with her own life on the line).
