Prologue : Is this the end of the world?
November 15, 2020, a crisis begins to spread across the world.
This crisis specifically affects only women, causing all men to become mentally unstable.
However, that is not the only consequence of the crisis. When all women perish, a system unexpectedly manifests. This system serves as a warning for imminent danger. Intrigued, a skeptical man approaches the system, questioning its authenticity.
To his surprise, a goblin and various other monsters suddenly materialize, leaving all men shocked and terrified. Nevertheless, in a turn of events reminiscent of a game, each man acquires unique powers.
Though possessing powers, the men are also ranked, with varying levels of strength. Progressing to higher ranks requires defeating more powerful monsters or slaying a significant number of lesser ones.
All men have no choice but to fight the monsters, fully aware that they may be killed in the process. However, if they don't fight, humanity will cease to exist, and no one will survive. So, all the men gathered and did their best to achieve this victory.
Days have past and now they successfully killed all the monsters, bringing them a sense of relief and joy. They believe that this is the end of the danger, but their happiness is short-lived.
Suddenly, the system appears again and notifies them that all the monsters they killed were just a low-level ones, and there are still many more awaiting to be unleashed through a portal.
This revelation causes them to lose hope, feeling overwhelmed by the seemingly never-ending threat. However, the system reveals a secret and that the system can also answer all of their questions because it is actually a human being - the most intelligent human in the world.
This human being, who possesses the power to see the future given to him by a god, he created the system back in 1990.
The purpose of creating this system was to save humanity and give them hope.
He barely managed to finish his task but succumbed exhaustion, resulting in his death. However, the benevolent god transferred his soul into the system, granting him the ability to control it.
Regarding the women crisis, although he could see into the future, he never foresaw a world without women. His preoccupation with creating the system prevented him from realizing or contemplating their absence.
As the system finished explaining, one of the men asked a crucial question:
"Will humans still exist in the future? Will we be able to survive?"
The system responded, stating that
"if you all fought, humanity would be saved and the future could be changed. It posed the question of whether all of you were willing to fight or not."
In an act of determination, unity, and the desire to change the future, they all decided to fight.
They supported one another, engaged in tasks such as cleaning, farming, and crafting the necessary resources, and prepared themselves for the battle.
However, a challenge arose concerning their sexual relationships.
With no access to women, they were left with no choice but to engage in same-gender relationships.
This situation prompted the establishment of a set of rules or guidelines to address this issue.
The rule regarding their sexual relationships states that if a man is rejected by the person he loves or desires, he can challenge them to a fight.
The purpose of this fight is to demonstrate that he is capable of protecting them.
It serves as a way to prove his love and commitment.
Once a man is already in a relationship, he cannot enter into another one. If his partner dies, he cannot pursue another relationship.
If a man successfully wins the fight, the person he fought against becomes his partner, and they will both receive a mark on their hands as a symbol of their committed relationship.
All the men have reached a consensus and approved these rules.
Violation of the rules carries strict punishments to deter further transgressions and ensure the survival of the community.
In recent days, a scientist made a significant discovery and it was revealed that the men in this community are immune to sickness and injuries due to their connection with the system. The system possesses the ability to heal any injuries or illnesses, and while it requires one day to complete the healing process, this is not a major issue. However, the real problem lies in the existence of the monsters awaiting an opportunity to enter the world through the system's portal.
If these monsters manage to escape, they can take advantage of the healing magic of the system to sustain themselves.
One month later...
A man of higher rank suddenly appears. He holds the top-ranking position, and upon discovering his identity, they give him warmly greet.
They all thought that he was there to find a partner that's why the residents offer to help him find a wife. However, he shows no interest in this matter, expressing his disinterest to them.
Just as he is about to depart, his attention is drawn to a man emitting an intriguing aura. Intrigued by this energy he unsheathes his sword and challenged him to a fight.
