Do you know how it feels when you are the last man standing over a mountain of corpses after an apocalypse
well John can tell you that it did not feel good at all if cells had more personality he would probably felt survivor guilt
"Seems like there were more than six mass extinctions"
(author note: yes I support The Holocene debate sue me!!!)
With his knowledge of astrology he concluded that this was a solar flare bigger than any in recorded history
"The damnn thing almost roosted me to death not to mention the sheer radiation damage it caused to my genetic makeup if I was not adaptable and sturdy as I was It was certain I would died did anything else even survive the flare???"
checking through his psionic hive mind he almost lost all hope but among the massive number of dormant or shattered strain signals there was one just one that was still giving off a steady wave of signals
resigning himself he swam through the graveyard of cells that covered the entire earth and dived to the deepest depths of the ocean eventually he reached an area of hydrothermal vents it was full of dead cells a massive graveyard like any other he had seen through his journey in all honesty even if they were just all cells this was just depressing
among these dead cells there was just one extremophile chemotroph cell that was still struggling from the extreme heatwave and massive radiation dose it received hours prior
but despite all this it was healing the radiation itself was helping it to mutate and create new unique gene sequences even its genetic repair regulations was extremely good second to his own even it didn't take long for John to know who this cell was normally scientist didn't give cells names only names to their species the cells would divide sooner or later anyway but this one
this cell was given the honor to get a name many billions of years later in the future by humans for its importance for life was unmatched John knew this cells name
