PROLOGUE

*** End of the Apocalyptic Wars, China, Monsters vs. Upgraded Humans of all countries ***

Above the Potala Palace and all of Lhasa were shrouded in dark shadows at midday as if it was a night, as the sky above the area was covered with hundreds of soaring humans and an army of monsters in front of them.

"ATTACK!" Bon-Hwa, The South Korean leader of the Human Army in scarlet-colored armor had pointed at the monster army in front of them... And the Upgraded Humans Army, some of whom were injured, proceed to attack the monsters again. Thus, hundreds of super-powered humans attacked more than a thousand winged monsters in front of them.

While the frontline warriors as Slasher-class tanks attacked with special non-man-made war weapons such as swords, axes, etc., Casters specialized in long-range attacks rained glowing objects like ethereal arrows on monsters. Passive supporters soared further behind providing support such as technical analysis of monsters that were helping injured people...

At the tenth hour of the battle, just at midnight, hundreds of monsters still alive suddenly moved sideways, giving way to their newly-joined leader.

"OF, GOD, ANALYZE THAT THING!" Even their leader, the strongest Upgraded Human on the battlefield, was frightened by the approaching monstrous colossal beast over 10 meters tall, with five heads and multiple animals' faces on each head.

The most powerful monster foe in human history was now on the front line and was coming to slaughter.

The leader of the Upgraded Humans, who had fought the monsters in front of him without a break until that moment, looked at his battle mates behind him. His worried eyes saw that half of them were dead and most of the rest were wounded.

"Even the power of our strongest is not enough to damage this thing. We have no chance of winning, we must retreat, sir!" Jianyu, who had fought bravely until now despite being one of the weakest on the battlefield, warned him.

"I can't leave another continent under the control of monsters to make it hell!" Their leader gripped the monstrous-shaped hilt of his sword, which was nearly two meters tall and wrought from a smoky metal.

"Leave it to us, sir! Please go with the rest..." The Japanese twin sisters, one of whom was the Detector and the other of the Caster class, who had served only for support purposes in the rear until that time, intervened. They glided toward the monster boss and other monsters, holding hands, and activating their suicide attacks, causing their bodies to shine like suns.

The body of the Detector class had completely disappeared and turned into a beam of light, and it had begun to flow over the chakram weapons inscribed with monster figures, created by the hands of the Caster class one...She has killed herself the supply power to her twin...

The Caster class sister, who was still alive, came to the front of the monster boss with the chakrams in her hands...And her chakrams, which had gathered energy throughout her arrival, began to glow in a way that scanned an area of ​​one square kilometer in an instant.

Finally, by killing herself, she loaded her soul energy into her non-material chakrams, and her chakrams grew larger. They produced a deep hum and turned the sky of the battlefield white, completely invisible, like a starburst.

At that time, Upgraded Humans and their leaders, who were fleeing to the opposite side to avoid being affected by the suicide attacks, looked back when the sky returned to normal after the explosion and saw that all the monsters, including their boss, were thrown back on the horizon and involuntarily flew far away.

While this attack wasn't enough to kill the monsters, it was enough to temporarily send them back to the invaded continents in the southern hemisphere and give humanity enough time to reorganize.

***

I am Jianyu, one of the warriors who managed to survive the Apocalyptic Wars.

It's been a few years since the monsters suddenly appeared and dragged the world into Apocalyptic wars...

At the moment when technological weapons were insufficient against monsters, we miraculously appeared, Upgraded Humans. Some of us have been bestowed with superpowers by an unknown power, and we have fought against monsters on the side of humanity.

We couldn't defeat the monsters, and they couldn't beat us either...Both sides suffered too many casualties...

As humanity, we lost the continents of Australia, Africa, and South America in the war and had to retreat to the northern hemisphere continents.

While we haven't lost our technology, nations have focused their remaining income on the survival of their societies, as our facilities that produce our essential life resources have been destroyed by monsters. Destroyed cities began to be restructured, and life on earth began to be rebuilt. Children and youth were trying to be re-educated in ruined school buildings, adults were trying to reconstruct their workplaces to create trade resources.

While all this was going on, our governments concealed the identities of Upgraded Humans for security purposes and reintegrated us into society as normal people.

Wild monsters living on the main continents we normally left them could sometimes appear in our lands, in these cases, a new task was opening in the pool of the program designed for us, and Upgraded Humans who were nearby have been summoned to the task.

Although the people in the regions we live in did not know our real identities, we, Upgraded Humans, were communicating among ourselves and even formed parties. We were going to the quests sent by our states with the parties we were members of, thus increasing our chances of victory against powerful monsters.

We were not hopeless though, because even though we lived in fear in our own world, there were billions of people still alive, and especially in the last few years, the appearance of monsters on our continents had dwindled considerably. Moreover, the monsters that appeared recently were surprisingly weak compared to their current level.

We didn't know why this change in their powers happened, but I can say that we enjoyed it as it gave us a huge advantage.

The hope of the people under the protection of the states and we were growing...

For Us, Upgraded Humans, the situation was a little different...

With this power we had, we could easily win against these monsters that have made our lives hell for years, and this situation turned out to be revenge rather than hope for salvation...

I could feel some superpowered Upgraded Humans around me slowly transforming into bloodthirsty beings...

Or I was exaggerating it, I don't know...

It wasn't that important to me right now anyway...

I was happy with it, for now, knowing that if it goes on like this, we will soon be rid of all the monsters and return to our old World order...

The fruits of heaven were approaching us now...

The fire of hell was no longer hurting us…

Jianyu's Party

*** A  few years later ***

Taking advantage of the darkness of the night, Jianyu and Murat sprinted out in their black robes from the remote corners of the city towards the forest field.

"What is the situation?" The leader of the party, Jianyu, called out to the other team members through the microphone of his cell phone headset.

"I see multiple enemy targets 5 kilometers north. I need to get closer to analyze better!" Malaysian Kirana, the group's Detector-class superpower user, answered over the radio.

"Keep following us, Kirana. It is advantageous for us that you are the detector class, but you are our weakest member. Don't put yourself in danger!" Jianyu ordered.

And they had reached their destination.

On the wide plain, worm-like monsters no more than half a meter tall were crawling slowly.

"What is this? Kirana, analyze these creatures" Jianyu called out to the Detector-type party member who had reached the battlefield five seconds after them.

"Ow, again! Damn it!" Murat, the Turkish Caster member of the group, didn't like the view he saw because they were the fourth extremely weak monster group they'd faced in the last three months, even though they had previously been reported as close to lvl30 strength. "How can they have such low instantaneous values even though they have such a high power and health limit?"

"Relax, Murat. It's better like this." "Relax, Murat. It's better this way." The Chinese leader of the group, Jianyu, had taken his sword out of its sheath on the way as a precaution, and after seeing the scene in the plain he reached, he sheathed his sword again. "Only eight of them. Finish them and let's get back to the city"

"Hey, guys!" The last member of the group, the Turkish Physician, Beril, had reached the battlefield and, attempting a dangerous type of courage, came to the side of the worm creatures and even cared for one of them by stroking the head. "I don't think we should kill them. They look harmless..."

"HEY, BERIL, ARE YOU OUT OF YOUR MIND? CAN'T YOU SEE THEIR LONG SHARP TEETH, GET AWAY FROM THEM, QUICKLY!" Murat raised both hands in the air and pointed them towards the monster Beril cared about, and the flashes of light that appeared in his palms took the form of a crossbow ready to launch its arrow.

"Stop, Murat! Haven't you seen his stats, even if he bites me it will do little harm, you don't need to do that!" Beril tried to stop Murat, but she was too late.

Murat shattered the monster into the pieces with the arrow he fired from his bow, which had 10 times the destructive power of the monster's instant HP, and then he killed the remaining seven monsters on the plain with arrows one after the other.

Then none of them spoke, and the party leader Jianyu looked at Murat and nodded, confirming that what he did was right.

However...

"SKIEEEKKKKKKKK" Ant-like insects began to emerge with high-pitched screams from the fluids flowing from the stomachs of the Toothed Crawlers they had killed. Hundreds of insects gathered in the middle of the battlefield, climbing on top of each other and forming a figure close to human size.

"What the hell are these things?" Murat, like the others, was watching the events in a confused and uneasy manner.

"I think those monsters you killed had eaten these things and disabled them before we arrived...And now they're free thanks to you!" Beril was still angry with Murat.

"GROOOAAARRGHHHHHHHHH" The insects combined to form a single body, and now a new monster appeared.

"Back off!" The leader of the party, Jianyu, drew the Vanguard Sword hanging on his back and stepped forward. "This thing looks dangerous! I'll take care of it!" He approached the one-and-a-half-meter tall Tasmanian devil-like creature in front of them and took a position to attack. "Luckily, those poor monsters have done enough damage to it before we get there, reducing its HP and mana."

Jianyu took action earlier and quickly rushed to the monster, swinging the flamboyant sword at its head.

"SKIEEEKKKKKKKK" Instead of its own roar, the monster suddenly shouted the screech of insects, and its body again disintegrated into hundreds of insects. And with this, it deflected the attack of Jianyu's great sword. The emerging insects gathered again three meters away, turning into the Dividing Rodent monster again.

Jianyu quickly rushed towards it again, attacking it, and the monster split into insects again, reuniting 3 meters away. But Jianyu was foresighted this time, and without turning around, he took a few steps back and slashed the emerging monster behind him from the bottom up.

[Target Hit]

[Damage -132]

<BATTALION!> Immediately after, he activated his skill and ran away from the monster. Five transparent clones of Vanguard swords appeared in the sky, and all five fell on Dividing Rodent and stabbed on it.

[Jianyu earned 1.010 experience points]

[Jianyu has leveled up]

[Jianyu has leveled up]

[Jianyu of the Origin Party is now lvl.17]

***

Jianyu had acted so quickly that he did not even allow his enemy to make a single attack. He was also right in doing this because Dividing Rodent had Attack Points that could kill even if it had a single attack on one of them even without using its skills.

"Wow, you are amazing, boss!" Kirana and the others had watched their leader's battle with admiration.

"Not so surprising actually. Our leader is a low-rated Slasher but someone who fought close to the leader of the Upgraded Humans in the Apocalyptic Wars and survived. We are so lucky to have him." Murat had always admired and proudly obeyed Jianyu since the first day they met.

"I took advantage of the Toothed Crawler having lowered it HP that much. If it had full HP, I wouldn't have had a chance!"

In order to continue to take advantage of the darkness before the night was over, they quickly returned to the city and dispersed to their homes without being seen by anyone, where they continued their daily lives.

*** Next day, Eskisehir State School ***

Jianyu and Murat were two 17-year-old teenagers studying at the same school in Eskisehir, Turkey.

After the Apocalyptic Wars, countries in and near the Southern Hemisphere had their surviving citizens immigrating to countries in the Northern Hemisphere for safety under the protection of the treaties. For this reason, Jianyu, who lived in the south of China, immigrated to Turkey alone, although his family lived in North China. In fact, while countries made these immigration agreements for the safety of their people, they also secretly made the distribution of superpowered people around the world equal.

Of course, since Jianyu couldn't tell this truth to his family, he left his country, telling them he just wanted to go.

"If we examine the ancient ages of world history, the Mayans..." The teacher was continuing her lesson with her students by writing on the functional parts of the blackboard, which was broken in half.

"Teacher, can I ask a question?"

"What happened this time Murat?" The teacher was tired of Murat, who was one of the most problematic students in the class, constantly trying to interrupt the lesson.

"Teacher, half of the whole world has disappeared, you are still forcing us to be distressed by the lessons. Look over there, our classroom doesn't even have half the windows." He gestured to the classroom windows, which were indeed half shattered. "I think it would be very motivating for all students if we could cut the lesson times in half. In other words, our lesson time should be equal to the number of windows."

"I'm really tired of you, Murat. I don't understand why the school administration still doesn't kick out a harmful student like you. Get out!"

"Then I'm taking Jianyu with me, teacher. You know, since I am the only person in the class who speaks Chinese, he cannot communicate with anyone but me. Even you get help from me when you ask him questions!"

Jianyu and Murat were walking along the corridors of the school that looked like a ruin.

"It was a nice trick." Jianyu had a smile on his face.

"If I have a better skill than my archery it's my deception ability, heh he"

"If my deception skill could be measured, it would be noticed to be much more successful than my archery, heh he...Also..." He looked at the interface of the secret program, which was designed only for people with superpower abilities, which appeared on the screen of the phone in his hand. "When will a Boss Event battle ever appear on our land again..."

The truth was that while they were in class, a new monster-killing quest had appeared on their mobile phones via software, and when they examined the details, they saw that it was a Boss Event that had only happened a few times after the Apocalyptic Wars…
