Ye Su's expression stiffened.

Now even the monster's name and its bug matched up with the game his company made. There was no doubt about it—he'd entered the game he was fixing bugs for, or a different world connected to it.

In other words, were there still plenty of monsters in this world that had gone beyond their original designs and started gaining bug-like abilities?

Like the monster currently facing off against Fiona in the street.

With a skill that reduced damage by 100%, no matter how much damage she dealt, it would all be nullified. It was like she was just tickling it.

The humanoid monster had been slowed by Fiona's [Blood Prison]. It hadn't taken even a scratch, but the slowing effect had already been applied when she cut into its body earlier.

“Human, it's no use. My body has received the blessing of the gods. No attack can harm me.” The monster, transformed into Boss Lady, spoke in a voice like withered, rotten wood. It was chilling to hear.

The people nearby grew even more frightened and hurriedly scattered in every direction.

“Run! A monster's made it into the city! What the hell are those useless mercenaries at the guild doing?”

“Oh my god, stop cutting in front of me!”

“Get the hell out of my way! Stop shoving me!”

It was all too real. When humans faced a crisis, all their worst traits came out.

At the same time, an alarm rang out at the Adventurers' Guild. It was the warning sounded only when a powerful monster was detected.

The branch guildmaster, a middle-aged man, had been putting up new quests on the notice board. His expression suddenly changed, and he hurriedly asked his subordinates to find out where the monster was.

“The residential district to the west—its magic concentration has reached... reached A-Rank! It's an A-Rank monster!” The young woman at the counter checked the direction shown on the detector and began reporting, her face full of alarm.

“All adventurers C-Rank and above, come with me and take a look! C-Rank adventurers, help evacuate the people. B-Rank and above, you're with me to take down the A-Rank monster!” The branch guildmaster had also put on his gear and come out of his room. He wore armor glowing a fiery red and carried an enormous, three-meter-long axe made from powerful monster bones combined with metal.

At the branch guildmaster's command, the many adventurers nodded in agreement.

In this world, guilds were spread throughout every country. They received subsidies from the state, but whenever monsters invaded, it was their duty to protect the people and drive the monsters away.

Of course, they were paid for it. Those who took part in emergency missions received money and commendations from the state. You could say they gained both fame and fortune.

In an instant, dozens of adventurers poured out of the guild. Among them were forty-four C-Rank adventurers, ten B-Rank adventurers, and one A-Rank adventurer: the branch guildmaster, who was charging at the front.

Since they often went on quests, many of them knew each other. After all, it was normal for adventurers of the same rank to team up, so they had plenty of experience working together.

They quickly split into several smaller groups and set about their tasks.

The B-Rank adventurers and the branch guildmaster headed straight for the monster's location.

Thanks to their strong physiques, the eleven of them reached the scene quickly. Most of the nearby buildings had already been damaged, and fires had broken out in several places during the fierce battle.
