[An adventurer has entered the portal.] [Due to the distorted measure of the portal, the portal is experiencing a breach.] [There are multiple layers of portals in this dimension. Portals will be differentiated with the use of numbers and classes. The adventurer(s) who have entered the premises shall defeat three of them to exit the area. Leaving the place is not allowed.] It was just as the portals had mentioned. Multiple panels materialised before me and bombarded my view. I could barely glimpse what was in front of me as the instructions piled up, coming from the three portals and how I needed to defeat them. [Portal #1 Class-A: Survive for 12 hours.] [A horde of monsters will emerge in your surroundings. Their number

A few hours had already passed by since the time I entered this place. I had already beaten a thousand monsters with my sniper. But there was no end to them. No matter how many my bullets penetrated, those magical circles would just respawn those bastards and bombard me. They were like rain. Furthermore, every time I killed a few hundred more of them within a minute, those beast would kill a dozen humans themselves. And the cycle continued. Unfortunately, as the time limit grew closer, dead humans increased. But my enemies remained infinite, even though my goal was to eliminate them. It was as if I got scammed by the portals. Fortunately, the people within the city evacuated for the time being. After four hours of protecting the area, the adventurers led the people to a different site, far from where I stood. A sigh of relief escaped from my mouth, knowing th

I used the rest of my minutes to study the attack pattern of this boss. Since these portals followed the rules of games, every monster had its attack patterns. Hobgoblins moved like they carried sands in their muscles, making their movements sluggish but impactful when they landed. The ideal way to deal with them was fast bullet attacks that would surprise the living shit out of those ugly-looking hobgoblins. Dodging their attacks would be a walk in the park, especially if I had my sixth sense activated at any time. Goblins were a different story. They ran as fast as an energetic child and dealt damage akin to an inexperienced martial artist. Dealing with them was a pain in the ass. The only thing that I had to do was aim my sniper at any goblin I saw and eliminate them one bullet at a time. There was no point in evading the goblin’s attacks, considering the damage dealt by these nuisances was nonexistent against my attire. Golems were slower th

I only had thirty minutes to do something. I kept defending the humans, hitting the Wyvern, while killing those monsters impeding me from doing my thing. Ideally, I was in the upper hand. Whenever my bullet struck the monster’s head, its health bar decreased. It wasn’t much, but it was something.However, there were still three things I had to consider.One was the time limit. The damage output my bullets could make was incomparable to the ones those small fry monsters did to me. I needed to fire my shots at least a hundred times just to bring the Wyvern’s health into half and another hundred to kill it. Firing ten bullets and repeating my routine took me ten minutes of my time. There was no way for me to survive and destroy the Wyvern on time.Two were the monsters. Every time I killed one creatur

The Ghastly Wyvern was faster than me. Its speed was incomparable to the jaguar or even the scurrying ostrich running away from its predator. And the worst part was the Wyvern was a dragon. That bastard could soar to the horizons using its wings, breathe scorching embers from its mouth, and hurl the rubbles from the ground. I was a sniper. Although I could shoot that thing from afar, it wasn’t enough to take it down. I needed more time to kill it, but the portal allotted time limit wasn’t enough for me. And those monsters respawning in various areas hindered me from dishing out my maximum damage. But even so, I didn’t give up. Never did. Midori, my parents, and the rest of those people who died outside the portal were counting on me. And even Hina. I did all of this for my step-sister’s sake. If I die right now, who would take care of her… That clumsy, awkwar
