The old man thought he was very familiar with the situation of this dungeon. This is the reserve base of the institute and the most important core part of the plan. If he had not received the activation instructions here a few days ago, the old man even thought that the city had been destroyed by that disaster. Although the way here was smooth, even so, the old man would have done a good job in the city, which would have been more than half of the city, and might even have maintained the idea of ​​only maintaining basic functions.

The old man is very familiar with this dungeon. He has participated in the design and construction of this place and knows what it looks like.

But... Looking at the scene in front of you, even the old man couldn't help but want to swear.

What is this?

I saw that in front of the old man was not the ruins he imagined, nor the urban buildings he was familiar with, but... a boundless green grassland.

Grasslands, woods, blue sky, and even the sun.

Wait, where is the sun coming from under the ground?

The old man raised his head and looked up again... That's right, the blue sky and dazzling sunshine. Although he knew that this might be some strange trap or hallucination, the old man still breathed a long sigh- he had never seen the sun again since the catastrophe.

"Be careful, be careful, let's go in."

Although the place in front of them looks weird no matter how they look at it, they have no way out, so the old man actually has nothing to do except to give orders to continue moving forward.

Although the order was issued, after entering this strange space, everyone felt confused. Looking around, they could only see the neatly trimmed grasslands like golf courses, as well as trees. On the entire grassland, there was only a path extending windingly towards the other side.

No matter how you look at it, it doesn't look like it should be found in an underground city.

“…………………”

Everyone walked step by step on the path, looking around curiously. They knew very well that the situation in front of them was obviously very abnormal, but they had no choice but to crack the situation. Now they could only rely on their leaders, and the old man did not say a word in the face of this strange scene. In fact, he was probably confused at this moment. After all, the originally familiar scenery suddenly flipped 180 degrees, and there was a completely impossible scene. Even if he was in this situation, he could not figure out what was going on in a short period of time.

"Doudududududu!!"

At this moment, suddenly, a loud horn sounded out of thin air. The next moment, everyone saw the four guards who were walking beside them suddenly wrapped in a semicircular barrier that looked like a film. Immediately afterwards, screams and fierce gunfire came from inside. When everyone saw this scene, they were also shocked.

"Sir, what is this?"

"Be careful! Everyone is paying attention!!!"

"Blow open that lid!!"

Amid the noisy screams, the others immediately moved away from the strange semicircular barrier. The other two guards immediately stepped forward, took out two small grenades from their waists and threw them over. They saw that the two grenades immediately burst out with bright and dazzling lightning and roars after hitting the barrier, but this attack seemed to have no effect on the barrier at all. Even if they fired with guns, the strange barrier was still as strong as iron, and there was no intention of being damaged at all.

"Swish."

Just when everyone was at a loss, they saw that the originally weird barrier disappeared in an instant, and then they saw the four confused guards walking out of it. Their bodies looked broken, as if they had fought with some beast. When they saw the four people walking out, the others hurriedly surrounded them.

"How is it? It's okay!"

"Is it okay, what exactly happened to you?"

"us………"

The four guards also looked very confused, and obviously they had not yet come back to their senses from the previous battle. It was not until the old man came to them and stared at the four people that they seemed to have finally come back to their senses.

"What happened?"

"That's right, sir."

Facing the old man's inquiry, the four guards looked at each other, and then one of the tall and thin guards stood up and responded respectfully to the old man.

"Just just now, the four of us were suddenly locked in a strange place, and then several ferocious monsters appeared to attack us. But... those monsters did not look like real things. After we defeated those monsters, they disappeared, leaving only this..."

As he spoke, the tall and thin guard stretched out his hand and placed a bottle of something that looked like some kind of drink or potion in front of the old man.

"What's this?"

"It seems to be... some kind of replies?"

"?"

The old man took the medicine bottle from the tall and thin guard and looked at it. Sure enough, he saw a few crooked words "Reply Potion" outside the bottle. Judging from the handwriting, it was not an industrial mass production printing, but rather a handwriting written by a child.

What's this?

The old man only felt that since he entered this strange world, the things he encountered had become increasingly unreliable. The data obtained through theory and experience in the past seemed to have no meaning here at all. However, even so, he did not show any wavering expression, but just put away the bottle of potion and continued to signal everyone to walk forward.

However, the next journey was not so smooth.

As everyone advances, they encounter monsters more and more. And almost everyone encounters the same pattern, first with a series of horn sounds, then they see the dark barrier appearing out of thin air, covering four unlucky guys. Then the others can only watch the battle and screams coming from the barrier. If everything goes well, then when the barrier disappears, they can see their companions again. If they are lucky, they can even obtain some strange props, such as leather jackets, wooden swords, and even various recovery potions.

But if they are unlucky, then after the barrier disappears, all they can see is the cold and terrible corpses.

After several battles, the others finally learned to be smart. They began to automatically find combinations to avoid encountering emergencies again in the next battle. It was as if at the beginning of the battle, a strange barrier suddenly appeared directly enveloped four researchers with no power. Not only that, they also heard the bandits' roar and sneer. When the barrier disappeared, all the people saw were four corpses that were covered by the bandit's mace.

Not only that…

"Please, please, who, who has the antidote......"

A researcher was stumbled on the road, and he stretched out his hand in pain, trying to ask others for a bottle of antidote. At this moment, the researcher's face was already ashen, and a purple skeleton symbol appeared above his head, as if he was laughing at him, and he kept opening and closing.

Not only that, with the action of the researcher, a number of "-1,-1,-1" always appeared on his head. But the researcher seemed to be careless about it. He just tried desperately to find something that could make him survive. However, in the face of his prayers, everyone turned their heads with guilt and stopped looking at him. Finally, after stumbled and walked two or three steps, the researcher fell to the ground with a bang and no longer breathed. His body gradually turned purple, and then began to rot and become suppure. He was one of the prides in the research institute, but now, no one looked at him. They were just like refugees who were desperately fleeing to the rescue and continued to move forward.

“Doududududu—!”

And at this moment, the horn sounded again.

But in everyone's ears, it seemed like the sound of hell bells.

“Wow…………………”

Looking at the picture on the screen in front of him, Kurona couldn't help but exclaim.

"I really didn't expect that if I just adjusted the value slightly, there would be such a change."

"Huhu, this shows that the master's theory is correct... I don't think others need to take risks, these people should be almost destroyed."

And Franka, who was next to her, still had an elegant smile.

"But they are about to reach the entrance to the second floor?"
