Now that I think about it before we fell, didn't it mention a reward box, I wonder where it went? Maybe it is in a subspace, or inventory lets try saying:
"Inventory".
A screen appeared which seemed to be an inventory that was game-like. It seemed to already have stuff in there. Reward box, water, lesser demon eye, lesser demon blood and a necklace, now that I think about it the necklace was on the lesser demon, I wonder what it does? But before that, I should give water to my sister, who is becoming dehydrated. I slowly poured the water in the sister's mouth, and she began to unconsciously drink it so she should wake up soon and then I decided to have the remaining third of the water. Hae slowly opened her eyes to see her brother looking after her.
"Thank god, you woke up," I said relieved.
But she was still confused about what happened and was dizzy as she still is hot. I had almost completely ruined my clothes and had cuts and scratches all over my body.
"Where am I? What happened to you?" she asked as she was worried about the wounds that covered my body and to see how much pain I was in when I made sudden movements.
"I killed a lesser demon, and we fell here which seems to be a cave of some sort, and these are just minor injuries so don't worry," I replied so she wouldn't worry.
"wow, you already killed a demon, you are amazing. But are you sure you are alright?" she was impressed but still worried.
"Yeah, I'm fine, I got rewarded with a reward box, The corpse of the lesser demon and a necklace, and I also found these daggers that buff me."
After that, I taught her how to use the inventory and how to add points to her stats and allowed her to treat my injuries so she could stop looking at me with such a worried look. It seems that she also got 10 points to add to her stats from the lesser demon as it considers her as part of my party so she put all of hers into intelligence so that she can use more magic that is more powerful she also levelled up due to shared experienced as we counted as a party she added her 5 skill points to stamina so she didn't get tired as quickly due to the harsh environment. I also told her how I got a new skill from the lesser demon due to my unique skill, but I didn't test it because of how unreliable it seemed.
A few hours passed, and we decided to climb out of the hole we fell into so I carried Hae on my back and climbed back to the cave we were initially in. Surprisingly most of my injuries had healed a bit and it was enough to move and breath properly although they still hurt.
"I'm sorry brother." my sister said although I didn't mind going through this trouble for her.
The fog that was previously, there had subsided, and as we carried on through the cave, we came to an opening. It was a cave that was about two football pitches big, and it was hard to see how tall it goes that also had gems and metals all over its walls with streams of lava flowing from numerous places. I had now placed Hae down as she claimed to be well enough to walk.
However, in this magnificent place, two lesser demons were fighting in the centre, and it would be a problem if we caught their attention. One lesser demon was tall and fat with a lot of power behind its blows as when it hit the ground it trembled and caused web-like cracks to form, and the other was small and fast dealing small amounts of damage with each swing, it was hard to see which would come out victorious.
We tried to sneak around to get to the other side which seemed to have another cave that continues onward however it turns out that demons have a very keen smell and love the taste of humans, so the two of them instantly turned towards us and started sprinting. There was no way I could get to the exit of this place in time, so I have to fight while protecting Hae, which will be hard but possible with a few injuries.
As soon as the small, fast lesser demon came close first, I took out my blades and tried to cut its neck however it suddenly flashed past almost as if it teleported, however, my blade did connect but didn't travel deep enough to kill it. The small lesser demon was heading straight to Hae and jumped to kill Hae, so I threw my knife which barely pierced the back of its neck which knocked it to the ground however with my back towards the other lesser demon I got hit and got sent to the floor which broke my arm.
"Brother!" My sister screamed as I saw her whisper something.
Suddenly the lesser demon went up in flames and started to panic. This was the result of a new skill Hae got by using magic manipulation, its name was [undying flames] which is a flame that is impossible go out unless the user is killed or runs out of MP however it doesn't do much damage. With the lesser demon now focused on my sister I ran to its back and repeatedly stabbed, after stabbing 10-15 times I could feel my broken arm healing, but it was painful, probably the worst pain I had ever felt but it wasn't enough to stop me from attacking.
The lesser demon is still on fire but is now concentrated on me, it swung its huge dull blade with tremendous power, but it was too slow. This might be due to me levelling up my stats, but the lesser demon seems slow, which will be its downfall. Seeing as the knife wasn't penetrating deep enough into its body, I jumped and threw the knife at its neck which severed its artery. However, it still stands. While it was bleeding out, I jumped up, and with all my force I used [Explosive shot] on its head which then flew off its body and landed a couple of meters away mangled and with a hole in it. It turns out that my cut to its neck weakened it enough that the rest tore when I used [Explosive shot].
I collapsed with exhaustion and Hae went to see if I was alright, she looked scared seeing me almost dead with a mixture of demon blood and my blood on me.
"it's alright now they are dead" I reassured her.
"you have defeated the lesser demon. You will now be given your points" the screen showed.
"Wait, why does it say I killed one dem-" before I could finish my sentence, I had a knife through my back.
