I Reincarnated As An Immortal Bat Into Another World

"What did that lady even want? To kill me for saving her? Just because I'm a monster? Dude, monsters also have hearts, and mine is racing," Bong said, his voice filled with a mix of confusion and frustration.

"I guess I need to level up faster. This world won't let me live otherwise," Bong muttered to himself, misinterpreting the lady's behavior as something negative, when she was simply wanted to express her gratitude for his help.

Bong started training again, realizing he could level up the proficiency of more than one skill simultaneously. He activated multiple skills to work on improving both of their proficiencies at the same time in his beloved cave.

After two weeks of dedicated training to level up his skill proficiencies, Bong finally emerged from his cave, feeling hungry.

[Proficiency of Shadow Stealth Upgraded: Skilled]

[Proficiency of Sonic Sense Upgraded: Adept]

"This is a significant level up! Let me check my status. 'Status' " Bong exclaimed with excitement,

[Name: Bong Jum]

[Species: Immortal Bat]

[Class : Shadow Bat ]

[Level: 13]

[Health: 500/500]

[Mana: 100/100]

[Innate Skill : Gluttony]

[Skills: Shadow Stealth (Skilled), Sonic Sense (Adept), Swordmaster ( Proficiency: Beginner)]

[Passive Skills : Soul Siphon (Beginner) ]

Bong grinned, pleased with his progress.

"Hmm... I need to suck more blood to level up my 'Soul Siphon' skill. It's time to head to the forest and find a nice evil delicacy," Bong mused with a mischievous grin on his face.

"And this Swordmaster skill, what a useless skill the system gave me. Do I swing the sword with my wings? I can only use it after I evolve into a Vampire. Ahh, I have a long way to go before I can wield a sword again," Bong mused, his tone tinged with a touch of irony.

[ALERT]

[Would you like to change the Swordmaster skill to something suited to your class?]

"Wait, what? I can actually change the Swordmaster skill to something that suits my class ?" Bong exclaimed, his eyes widening in surprise, a mixture of excitement and disbelief evident in his voice.

[ALERT]

[YES]

"Then why didn't you tell me anything useful earlier, you darn System?" Bong exclaimed in frustration, his tone laced with annoyance.

[ALERT]

[You never bothered to ask, did you not find it strange? Swordmaster skill on a bat, what a foolish host I am stuck with]

[There's a setting in the top right corner. You need to set the command to choose the skill suited to your class by Gluttony. Gosh, bat eyes!]

"This darn system, I better not anger it, or I'll just end up suffering. Fine, go ahead and change my Swordmaster skill," Bong grumbled with a hint of resignation.

[ALERT]

[Changing: Swordmaster skill]

[Analyzing host's class compatibility]

[Suited skill found: Shadow Manipulation]

[New Skill Acquired: Shadow Manipulation]

"Shadow Manipulation?" Bong exclaimed, his voice a mix of surprise and curiosity. 𝑏𝑒𝑑𝑛𝘰𝑣𝑒𝘭.𝑐𝑜𝑚

[Shadow Manipulation : Allow you to control over shadows in his vicinity, enabling him to shape them into solid constructs for defense or offense]

"At last, a skill that can help me fight monsters and defend myself," Bong remarked with a sense of relief and satisfaction.

"But let's wait for night. It will benefit me more during the night - a bat lurking in the shadows, ready to suck the blood of evil beings," Bong chuckled to himself, his anticipation evident in his voice.

As Bong patiently waited for the night to fall, he ventured into the forest in search of his prey. Utilizing his shadow stealth, he gracefully moved from one shadow to another, becoming nearly invisible in the darkness. However, his exploration took an unexpected turn when he stumbled upon a newly formed dungeon. Adventurers were entering the dungeon, driven by the desire to loot the hidden treasures. Bong found himself encountering humans once again, but this time he decided to let them be, realizing that they were adventurers and not malevolent bandits.

Just as he was considering leaving, Bong's acute hearing caught the sound of someone screaming. The scream echoed from a spot near the dungeon, a few steps ahead. What struck him as odd was that although the scream was loud enough for everyone to hear, no one seemed to be rushing to help. Intrigued, Bong, who was a distance away, employed his 'Sonic Sense' skill to observe the scene. His enhanced senses revealed a distressing sight: four adventurers were mistreating a young boy.

"I guess I've found my evil delicacy for the night. It's dinner time, Bong," he chuckled to himself with a mischievous grin.

Bong maneuvered through the shadows using his skill 'Shadow Stealth' and reached the scene. He decided to observe the situation first, trying to determine if the adventurers involved were truly evil or not.

"I am sorry, Young Master. I forgot to bring the sword, thinking that you would prefer to select it yourself," The young boy knelt on his knees, his voice trembling with apology as tears welled up in his eyes.

"You mean to tell me that you thought I would retrieve the sword myself? You, as my servant, are supposed to handle such tasks," The young master raised an eyebrow, a mixture of surprise and confusion crossing his face.

"Do you even know the gravity of your actions? You've turned me into a laughingstock in front of everyone. A young master who forgot his own sword, all because of your incompetence," The young master's voice dripped with frustration and anger.

"I cannot tolerate this humiliation. Boys, let's kill this insolent foolish servant. I have no need for such a pathetic servant," His voice oozed malevolence and sinister intent as his expression twisted into a wicked grin.

"My ears will bleed if I have to listen to more of this young master's nonsense. I suppose no one dares to interfere with him just because he's a noble's son. What a cruel world," Bong muttered to himself, a mixture of annoyance and frustration in his tone.

"He's about to kill him. How can I save him? There are four of them, and I'm just one bat," Bong thought, his voice tinged with worry and uncertainty.
