John woke up in an unknown place, when he tried to get up something was getting in his way, it was a very heavy thing.

But after putting some force he managed to get it off, when him take off that object that covered his vision, he found himself in an incredible place.

He was in a totally dark cave, and at some points in the cave was full of sparkling diamonds, it was a magnificent sight.

But John doesn't remember coming here, he remembers very well sleeping in his bed as usual, so how is he in such a strange place? It makes no sense.

When John got up he felt his body totally lighter.

'I weigh over 100KG how can I be so light?' That's what John was thinking at the moment, nothing that is happening here makes sense.

As John continued to look around and was trying to figure out what happened, something strange happened in his vision.

An all-red screen of deep color appeared in front of him.

It was something like a VRMMORPG game, it was totally crazy, and it was happening right in front of your eyes.

***********************************

[Welcome to the system]

1st Mission - Exit the cave safely.

Reward - 10 EXP, 10 GOLD

****************************************

But what is this, is this really a game?

Get out safely? Now will you tell me that there are monsters and stuff like that here too?

But there was something else bothering John, as he looked at the system screen he could see your skin and it was totally pale color, it was a color that John did not have.

John always had dark skin since he was little, so it made no sense, but another thing John realized was that his hair was giant and was hanging in front of his breasts.

But the worst thing was having that feeling between my legs, John couldn't feel anything, it was like he wasn't a man, how is that possible?

John realized that inside the cave was a large pool of crystalline wather, and when he got there, he was startled by his appearance.

John was now completely pale and his hair was completely white.

His eyes had a blood-red color, a totally wonderful look.

'But wait there? Am I a woman? "John was very confused at this point, how could his sex have changed overnight? And how did he end up in this place? What is this system? That makes no sense!

******************************************

What do you mean penalty?

How would I get out of this cave? I don't even know exactly where I am, could you give me a map?

As soon as John said the word map, a huge map appeared in front of him, the map showed all the paths of the cave, the cave was totally a maze.

If John failed here he didn't know what the penalty was, so he was quite afraid of it.

"System, could you show me my status?" John asked the system, because if it were like a game, the system would show something like all his skills or something.

Wait, what do you mean, vampire?

It really surprised me.

'How had I not yet noticed the ears and fangs?' My ears are pointy and I've got fangs, am I really a vampire? This is really interesting.

But nothing changes the fact that what is happening is extremely confusing.

Nor does it change the fact that I have to fulfill this mission, otherwise I will suffer a penalty.

//

John started to look at the map and walk through the cave, him had no idea where to go, even looking at the map, he could not know exactly where the exit was.

*******************

Time left to leave the cave: 30:12

Failure will result in a penalty.

**************************

It had been 15 minutes and John was still lost inside the cave.

John was also scared of this cave because the mission asked him to leave the cave safely, so clearly there must be something inside that could hurt you.

John kept walking through the cave, but then he heard a noise of something goo falling, it was a little disgusting sound.

When John looked back, was an extremely cute monster.

"Is that a slime?" It looked like a Slime that was found with RPG games, it was really cute.

When John looked at Slime the system again resolved to help him.

*******************

[System Message]

Monster: Slime

Level: 1

Strength: 9

Agility: 9

********************

Yes that was exactly it, it was an initial monster of any MMORPG so it would not bring any danger to John.

'Do I really need to kill it?' That's what John was thinking.

John was staring at the Slime and wondered whether to kill it or not since it looks so cute to him, and didn't think that it could hurt him.

John didn't need to kill it, but he needs the experience required to level up. He doesn't quite know how the system works, but he knows of one thing, and that is he needs to get stronger if he wants to survive in this place.

Because monster like Slimes exists, there are certainly monsters out there of unimaginable forces. John didn't want to find a monster of such level inside this cave, He didn't even want to imagine something like that happening.

I guess I'll kill this slime, John thought and decides to kill the jelly-like thingy squirming in front of him. Although John had no weapon in his hands, the Slime also didn't have any. But then again, John has never seen a Slime using a weapon before. Also, the system already showed that his strength and agility is way above the Slime.

John slowly approaching the Slime and before the Slime could do anything to him, He stepped on the Slime with all his might. But what surprised him was the moment he stepped on the slime, it exploded and flew all over the place which caused him to jumped and put up a distance from the place.

Although the scene was pretty shocking, there is also something else happened that caused him to be in shock. John narrowed his eyes and looked toward the place where the slime died and saw a pale light floating around it.

The pale light was floating midair exactly where the Slime had been killed, it was quite a surreal sight.

Although John didn't know what the pale light means, he slowly approached it but was surprised when it suddenly entered from his chest, and a good feeling spread to his whole body. It was very satisfying.

***********

[System Message]

Experience gained: 1

Objective for Level 2 - 1/100

***********

So this is how the experience works? It's extremely practical that I just need to be close and the pale light will be sucked into my body.

"I have to keep walking."

Because John had yet to escape from this dark cave, he started to sprint forward while looking at the map in his vision. Although he keeps on staring at the map, he still ended up either running into corridors or comes into dead ends. It was hell.

As he ran through the cave, he also met some Slimes along the way. He ended up killing every Slimes, just because he wanted to feel that wonderful sensation again.

...

'What the ****?' John's mouth was completely dry and cracking. He felt a horrible thirst, but when he drank water, the thirst still didn't go away and it was driving him crazy.

'Is that it?' John finally remembered that he was of the vampire race, so he already know what he would have to drink to quench his thirst.

***********

[System Message]

Dehydration for lace of blood - 2/10

***********

Wait a second, dehydration? What will happen if that number reached 10? This is getting ridiculous.

First, he was turned into a vampire who needs blood to survive, and the system also told him to escape this cave or If I fail to do so will result in a penalty. There's no way in hell John would want to drink the human's blood since he was previously a human, after all.

'Damn, I have to get out of here and find something to drink, animal's blood or something.' John didn't want to drink the human's blood, so he would have to quench his thirst by drinking another kind of blood. He was thinking of drinking the blood of an animal, but he doesn't know if that will help in his hydration problem. But then again, he could give a try if he ever escapes from this cave.

Although everything so far looks like a game, John didn't want to die and was worried that if he dies here, he would be gone for good. To John, everything he has experienced so far still feel like a bad lucid dream. He also didn't want to find out the truth in the hard way.

"well, All I have to do now is run and find a way to get out of here. There's nothing else for me to do."

With a strong determination to escape from this dark cave, John continued running through the cave while slaying slimes on his way.

As john progressively running through all obstacles in the cave, 'That's it, I'm getting closer!' eventually, he could see the light coming from the exit of the cave far in the distance and when he looked at the map, he was on the right track.

***********

[System Message]

Dehydration for lack of blood - 6/10

***********

As he gets closer to the exit, John couldn't feel his legs anymore. Dehydration is really on another level, he felt so tired and his head was spinning, it was truly a horrible feeling. But even so, he had to move forward, he need to escape from this cave as soon as possible!

Sniff--

'What is this smell?' John felt a sweet and wonderful smell, something he had never felt in his entire life assaulting his nose. He couldn't help as his mouth starts to salivate all over.

John, who was already on the brink of madness, didn't care about anything anymore and started to sprint towards the smell, and the closer he is to the sweet smell, the stronger his thirst becomes.

When John reached the place where such a wonderful smell was the strongest, he came across something he never imagined to find inside the cave.

It was human.

Yes, John was seeing human for the first time after awakening into this dark cave, but to the current John, the human in front of him looked just like a piece of meat that was waiting for him to devour.

'ATTACK THEM'

'SUCK THEIR BLOOD'

'KILL THEM'

'BITE THEM TO DEATH'

"Stop!" John was hearing several kinds of voices in his head telling him to attack those humans over and over. He was trying his best to control himself, but in the end, it was in vain. He could hear something snapped inside his head before losing his conscious for the first time in his entire life.

John ended up losing his sanity.

***********

[System Message]

Dehydration for lack of blood - 9/10

Bloodthirst mode activated!

***********

When John lost control he jumped toward the humans who were on from the cave.

Nor did it give humans time to react to the attack; John was already in front of them in an instant, it was like a figure appearing in their visions.

*********************************

[System Message]

Bloodthirst mode activated.

Strength and Agility X4.

***********************************

John didn't even notice the system warning, but when he goes into bloodlust mode his body gets very strong.

His strength and Agility are 4 times stronger, for him who already had 86 and strength and 96 agility, today he was a monstrosity.

The humans were in a group of 4 people, 2 men, and 2 women.

John couldn't even tell who he was attacked because he had practically lost all his consciousness.

John who attacked the humans jumped on a girl's neck so hard that her neck twisted and broke at the same time, the only thing his groupmates could feel when watching this scene was terror.

They were in a state of panic as their friend was killed in front of them and they could do nothing.

They could only think of running at that moment.

That was the worst day of their lives.

//

My name is Jeffy, I'm a D-RANK adventurer, and I and my group are now going to explore a cave the guild requested.

It looks like the cave is a low-level cave so there is no danger to our group.

My group has 3 more people, Doug, Lena, and Mily.

Our group is considered very strong for our RANK.

All the members of the group are in D-RANK, so, we can get along if it's a D-RANK monster which is already considered very strong.

"Let's go in," I said to my group at the cave entrance.

We wanted to finish exploring this quickly as we were in a hurry to raise our RANK.

"Lena and I go ahead, Doug and Mily stay behind for support." I always gave instructions to our group.

We always battle like this, with Me and Lena in front with Doug and Mily in the back.

After giving the orders we entered the cave and began to explore.

That was the worst decision we ever made in our lives.

As we entered the cave and began to explore, a huge figure appeared from the shadows of the cave.

We had no time to do anything.

When my colleagues and I realized, Lena was already dead.

Lena's neck snapped instantly as the figure attacked her.

No one could see the creature very well, so Mily behind her used fire magic to illuminate the creature's face.

When we saw what it was we could see a woman with silver hair stuck to Lena's neck.

"It's a vampire, we need to get away now." Doug who realized what it, started running.

"Shall we leave Lena's body here?" It was Mily who said that she was still crying over her friend's death.

But we can't stay here, if we stay we'll die like Lena.

"Mily, we need to run," I said to Mily and grabbed her arm.

When we saw, it we were already outside the cave.

We just lost a precious friend.

//

John jumped on the girl's neck and kept sucking her blood over and over.

He couldn't contain the urge to suck all that blood.

That sweet and wonderful taste he was feeling, he had never felt in his life, so he couldn't help but keep on tasting it.

'I need to stop.' John who had a rest of conscience was crying as he tried to stop attacking the girl, but he couldn't contain that feeling.

By the time John noticed, all the girl's colleagues were gone and all that was left was the pale white girl's body without a drop of blood.

"What did I do?" John knelt beside the girl's body and began to cry.

He had never killed anyone before, but because of a stupid system, he just took a life, and the life of such a young girl.

***************************

[System Message]

Now, will you say that I need to kill people to evolve? Are you kidding me,  your shit system?

This is crazy, I could never kill people just to satisfy my will, I'm not a fucking psycho.

John, who could no longer see the girl's body, decided to bury her right there.

He was sure her friends would not return to seek her out, but she deserves a decent burial.

John dug a hole in the cave floor and buried it there.

It took a while, but it made him feel a little better.

"Eh?" When John had calmed down, the system message suddenly came, it was a message he didn't want to see.
