First dungeon

"Yeah. My legs muscles just grown thicker a second ago. Isn't it amazing?"

[ 🤦 ]

I don't know why tsundere system facepalm at my words. But my little sister just smiled, and giggles.

She telling me that I've never change so I just kept talking and telling jokes with her until I'm bored.

Well...We've been sitting in the same seat for about 3 hours now. And my little sister always rubbed her body against me, so my body produced a lot of heat and sweat against my will.

She asked me if I would like to take a bath. But I just refuse it and leaves the house.

My house located at the furthest from the central region of the city, and there is a wall next to my house for preventing any monsters to break into the city. So it's can means that if the wall was broken, the one who will be attack first would be us.

Nah. That would not happen as long as I am here.

Why? I dunno man, seems kinda safe to me.

"OK. Now I'm going to be the best hunter there ever has, and I'm going to catch all the gates!"

[ *Ding* Mana fluctuations nearby. The gate gonna be open anytime soon ]

Just about to take one step ahead. The air vibrating and the gate that looks like wormhole appeared in front of me.

And I can't take a step back because about half of my body has gone in.

[ Congrats, Host. For entering C-rank Gate for the first time ]

[ C-rank Gate : Big tomb of the 💩🙈🙉

-Sub dimension of the world in the 👽🤯😻 galaxy in 🤣😢😭 universe. A replica of the Great tomb of the 😱🤷😒, since this is only a replica, there'll be something missing and something added. Laws of both world, universe, and dimension are not valid in this sub dimension. Engage with cautious. ]

Wow. So random.
