"Hey, wait, we have to stay together, " I chuckled and followed her.

*Hmph* Natalia looked back and snorted.

We continued exploring the dungeon and arrived at the 60th floor. On this floor, we fought the boss, Elder Lich. This monster is at B+ rank, but because of our cooperation, even though Elder Lich is at B+ rank, we were able to fight it without any trouble. The Elder Lich had a spell to summon many nearby skeleton troops. He also had a curse spell.

Luckily for me, with Berserk Mercilessly, I don't have to be afraid of curses and stuff like that anymore. I think the weakness of this skill is that it is only useful for my physical body. If a curse threatens my soul, I guess it will be useless. And also, using this skill consumes life energy. I can't keep relying on this skill.

The Elder Lich cast a black fireball spell at me. I moved, spinning in the air, cutting the skeleton into ashes and making a chain shield block its attack. But it turns out that the attack was so strong that it sent me flying backward.

"Fox Aihars,"

Silvie placed her hands on the floor, then a firefox manifest appeared behind her. The fox circles through the air before moving towards the group of skeletons and towards Elder Lich. The Elder Lich cast a spell, and the skull head manifest moved towards the fox.

An explosion occurred, causing skeletons that were in the vicinity of the attack impact to shatter into pieces. As Natalia shot the remaining skeletons with her cannon, I silently used my invisible ability and arrived behind Elder Lich. Unbeknownst to him, I used my sword to pierce his back to his chest. The Elder Lich shouted before turning to ash.

"Good job, Lute,"

"You too,"

Silvie and I smiled with our cooperation, while Natalia continued to pout and snort. I just shrugged my shoulders and let her. I remember we were about to reach the last floor. This dungeon only had 70 floors, and on this floor was an Icebound Sword. There was also a weapon that caught my eye because, even in the story, the protagonist didn't dare pick it up.

That weapon was sealed together with the Icebound Sword, or should I say, the Icebound Sword sealed that weapon. That weapon seemed to be sealed for some reason, but that's what attracted me to it. But sadly, even in the game, I didn't know anything about that weapon because it only appeared in this dungeon and was left behind and not talked about in the story anymore. 

'I wonder what caused that weapon to be sealed. Is it a cursed weapon?'

Holding my chin, I thought I'd figure it out after picking it up later. We then headed for the treasure box that lay on the floor. When I opened it, there was another box inside. Natalia took the paper from the box and read it.

"Dimensional Box, capable of holding anything except living beings in a different dimension. Every item stored will not rot or be damaged," Natalia read this with sparkling eyes, and without speaking to us, she immediately took the box.

"Ahem, this box is for me. The item in the next boss's room is for you," She said.

Silvie and I looked at each other and we both nodded. The box wasn't of much use to us anyway. Especially me, who has an inventory system, while Natalia needs this because she brings a lot of stuff with her.

We then continued to explore the dungeon. I don't know how much time was spent in this dungeon because the only light here is the torch on the wall.

"I thought we'd rest here. I'm sure you guys are tired too," I said to

"Okay," Silvie nodded.

Natalia also nodded, because she also felt that her mana was low and she needed to recover herself again. I sat down beside Silvie and gave her a potion, then I took out the lunchbox I had prepared beforehand.

"Silvie, open your mouth, Aaaa..."

Silvie's face turned red, but she nodded, opening her mouth. Seeing her obedient, I smiled and continued to feed her. Two of us ate peacefully until a voice sounded from in front of us.

*Growl*

Silvie and I turned towards the voice. There was Natalia, who had a red face with embarrassment. It was the sound of her stomach being hungry. I laughed, then showed her the omelet roll.

"Do you want me to feed you too?"

"Wh-who wants to be fed? I'm not hungry at all,"

But then her stomach growled again, and her face turned bright red. She didn't prepare any supplies beforehand, because she wanted to quickly explore the dungeon and didn't think she needed them at all. But who would have thought? It turned out that she was feeling very hungry now after a tiring battle.

"I'm kidding. Eat this. It's not good for the next battle if you feel hungry. " I laughed and gave her a sandwich.

Natalia looked hesitant to take the sandwich in my hand, but she couldn't take her eyes off the sandwich either, and saliva dripped down her lip corner. I smiled, bringing the curry sandwich closer to her. She then quickly grabbed it and ate it voraciously.

"How? Do you want more? "

Natalia looked embarrassed, but she nodded her head. I then prepared another sandwich and gave it to her. After that, I returned to feed Silvie. We ate together.

Silvie and I fed each other, which made the atmosphere around us look intimate. Natalia, seeing this, had a sullen face. She felt like a third wheel now. But then she ignored it and continued eating in annoyance. I saw her like that and could only chuckle.

After we finished eating, we continued exploring and finally arrived at the 70th floor, which is the last floor in this dungeon. Taking a deep breath, I slowly opened the red gate that looked dangerous in front of us.

A large room, like a king's room, was visible. There was a throne there that was occupied by a knight wearing ice armor. She didn't have a face at all because it looked dark, but she had two red-glowing eyes staring intently at us. Behind the throne, there is a bluestone surrounded by sharp ice chunks.. What attracts attention is beautiful blue crystal-like sword stuck in that stone.
