While Graham and Rhea were having the time of their lives, the world was in utter chaos.
Not everyone had the capacity to kill those monsters and then go on to enjoy their life like nothing happened.
Even Rhea with her experience as a top tier assassin struggled to kill even one of those monsters before her level ups. The state of rest of the world's weak level 1 humans could only be imagined.
Though everyone's stats were streamlined to an average of 1 by the introduction of mana, It doesn't mean all of them could optimally use it.
So, within that one hour before the portals were closed by the Universal System, almost 20 percent of the world's total population died - killed and devoured by the monsters.
The percentage of death would have been even higher, if it wasn't for the fact that the world's current weaponry was atleast able to repel those monsters and reduce the casualties.
Everywhere one looked on the surface, there was only death, destruction and the wails of anguish from those who lost their family, their friends or their lovers to the monsters.
But when those portals opened above the sea, aside from some of the amphibian monster types thriving there, every other monster fell into the water and started desperately swimming to return to the land.
Of course, the predators of the sea - Killer whales, sharks, sea bears, leopard seals and others - took perfect advantage of their inability to defend in the water and killed some monsters with hit and run tactics, leveling up in the process.
And It didn't stop there. Now that everything was steeped in mana and the world was integrated into the system - each kill rewarded exp no matter how small - result being the sea beasts continuosly leveling up through killing.
So while the land dwellers were suffering, the sea was only becoming more and more dangerous with each passing moment.
What will be result of this fast evolution? - only future can tell.

Getting up from the bed, Rhea went to the bathroom to clean herself, especially the dried fluids all over her body that were the evidence of their lovemaking.
Graham wanted to accompany her inside of course, but she chided him in her strict teacher tone saying that if he came inside, it wouldn't end with just a bath since he couldn't keep his hands to himself.
Having denied from his bathroom sex, Graham planned to go for broke and gave her a lost puppy look with the most innocent expression he could muster.
Fortunately, it was very effective - melting right through her heart and faltering her strict demeanor.
Graham took advantage of her momentary hesitation and picked her up before going inside.
There, they had a long, and hard...
bathing session that lasted another hour, before finally coming down to the living room.
Rhea wore some simple comfortable clothes to relax - an oversized white T-shirt along with a pair of baggy blue pants.
And since Graham didn't have any clothes to change into, he just borrowed one of her bathrobes before both of them reclined on the couch together.
Leaning her head on his shoulder, Rhea looked up and met his eyes before talking with a questioning tone,
"Now that you've had your way with me, you're not just going to go ahead and disappear on me right?"
"Of course not." Graham replied.
"Why would I leave behind my cute and lovely teacher that was also a bit of a pervert in bed."
Hearing it, Rhea's face turned slightly red. Before she could object saying that he was the damn pervert, Graham closed the gap and brought his lips inches from her ear - before whispering in a possessive voice that was bordering on obsession.
"Besides, the moment you accepted my advances, you've already become mine. Even if you regret it and want to leave now, I will never let you escape from my clutches wifey..."
A shiver went down Rhea's spine because of his assertive words and his declaration - of her being his wife.
But she didn't hate this possessiveness.
In fact she loved every dangerous word that was escaping his lips because of it, Her amethyst eyes darkening with possessiveness similar to his own.
"That's more like it, Hubby...", she finally replied with seductive voice, before kissing his lips with a burning passion.
Graham responded with equal passion not letting himself to be outdone.
Though he could only control himself from going further, since her body really couldn't take anymore of his pounding.
Pouring out both of their emotions through the intense kiss that lasted for minutes, the two finally separated from each other gasping for breath.
"Haa... Haa... Haa..."
"Haa... Haa... Haa..."

Catching her breath, Rhea decided to talk about serious matters, asking Graham,
"How were you able to kill those monsters at the school so easily?"
"From what I know, you were always a bookworm, focusing on his studies to get entry into the medical college. Even after graduating, I heard from your friends that you haven't changed much."
"So how did you become so powerful all of a sudden, killing those monsters as if they were nothing worth mentioning."
Graham retorted with a question of his own, "I could say the same about you, you know?"
"How did my sweet and delicate teacher suddenly become an expert killing machine- that wouldn't bat an eye even after killing swathes of monsters and leaving rivers of blood at her wake?"
With Graham dodging her questions, Rhea could only reveal her past with an indignant pout.
"I was an assassin working for the government before coming to teach you guys. The government took some of the talented orphans out there to train them, into becoming fine blades for doing their dirty work."
"Working tirelessly and accumulating plenty of contribution points, I retired and became a teacher since that was my goal."
"There I said it. Happy...?"
"Now answer my damn question. How did you become this powerful?"
"You won't believe me even if said it, Wifey." Graham chuckled wryly.
"Try me." That's all he got in response.
Giving her the benefit of the doubt, Graham faced her with a serious expression before recounting his past.
"In this universe, earth isn't the only planet with intelligent lifeforms. There are trillions of planets thriving with life in the wider cosmos."
"And unlike earth, they had been exposed to mana millions of years ago. With some of their inhabitants becoming so powerful- so much so that they can literally blow out this entire solar system with a single breath."
"And I..."
Exhaling a murky breath he didn't know he was holding, Graham continued.
"I was the strongest of them all."
"Standing at the peak of this universe, as a Godking, no one else was my equal."
"But other gods coveted my power. And in their jealousy, they joined hands with each other to bring me down."
(Graham decided not to mention the foreign universe for now, deciding to talk about it in the future when they would venture into space.)
"After my death, by some miracle, I reincarnated in earth as the Graham you knew."
"Of course before dying, I made sure they paid in blood for my demise..." He proclaimed with an arrogant smirk.
"I also only recently regained my memories. Otherwise I would have taken you for myself way sooner."
Graham finished his story with a slightly regretful expression, like it was only natural that Rhea became his woman in one way or the other.
What met Graham after he finished his monologue was...
Silence.
Pin-drop silence.
Rhea just stared at his face with a blank expression, without saying anything for a long time.
And then,
"Pftttttt.... Hahaha...."
"Hahahahahahahaha...."
She burst into uncontrollable laughter...
doubling down and clutching her stomach, with tears in her eyes.
