In 2018, unknown portals appeared all over the world, and at that time, the news and topics about portals were well known, and nothing happened after the portal appeared, and there was very little information about the portal, although the sudden portal appeared in people's field of vision, but everything was going on as usual.

All this was reversed at the end of 2018, when the end of the year was a day of rejoicing in country Z, and just as the clock struck zero, the portal in the capital of country Z opened.

A huge arm stretched out from the portal and slapped heavily on the ground, this huge sound attracted the attention of people who were still laughing and laughing next to them, but before people could react, a huge monster came out of the portal, the monster was the owner of the huge arm, and the people around saw this scene and immediately fled around, but because of the large number of people, coupled with people's fear, they were not well evacuated.

The monster rushed over as if it had seen a feast for the people fleeing in all directions, and after ten minutes, the place that had been bustling with activity became as terrible as hell.

The well-fed monster raised its head and roared to the sky, this terrible roar seemed out of place on this originally happy night, and the police who arrived at this time saw the horror of this monster and the messy environment around it, all of them were terrified, but the monster would not waste this meal in vain, and finally this monster was killed by the army, and when people thought it was over, the portal came out again with a monster that was even bigger than before, but this time it was not one, it was followed by a group of monsters like it.

It's not just country Z that has monsters, it's also country M, country E, country Y, and country F...... Monsters began to appear in the portals, and the armies of various countries resisted hard, but they could not stop this flood of monster armies, and finally the countries of the world used nuclear weapons to barely win the war, which is also known as the "beast tide".

In the year of 2019, the portal also continued to open, but it was not as difficult to control as the beast tide, in this confrontation, there were some "superhumans" with different abilities in the crowd, and how their abilities came from is as unknown as this portal, "superhumans" and portals are like the two ends of the scales balancing each other, and the country gradually realized the role of these superhumans in the battles against the portal, and slowly reused, in the world conference, these superhumans were given a name "hunter"

Slowly hunters play an important role in the portal battles again and again, and slowly hunters have become the mainstream, and the hunters are also divided into levels, from weak to high, they are D-level, C-level, B-level, A-level, S-class. D-level hunters are no different from ordinary people, undoubtedly they run a little faster than ordinary people, C, B, and A-level hunters have some special abilities or kung fu attainments that are higher than ordinary people, and S-level hunters are hunters who can subvert the entire country with the power of one person, so there are very few S-class hunters.

In the years that followed, various nations spawned S-class hunters, and the nations gathered them to enter the portal and defeat it in one fell swoop.

In the spring of 2021, a battle plan called "Annihilator" was adopted by countries around the world, this plan is to gather all the S-class hunters in the world to gather together, enter the portal, and completely solve the portal problem, a total of 30 S-class hunters were gathered, and they entered the portal with the responsibility of saving the world, and we don't know the battle situation inside, in the six months since they entered the portal, there have been no more monsters in the portal.

In the early winter of 2021, these human heroes came out, and countless people went to the portal to greet them, including their parents, their wives and children, but only 10 of the 30 hunters who entered the portal slowly walked out of the portal in the end, and the people who greeted them quieted down when they saw this scene, and the hunters who came out fell to the ground one by one, and the medical staff on the side immediately sent them to the top hospital for treatment, and the people in the crowd who did not see their families come out safely knelt on the ground and cried, After that, the countries signed confidentiality agreements with the hunters who entered the portal.

The efforts of these 30 hunters brought peace, and in the years after that war, the portal was no longer moving, and the hunter became a national hero.
