Transmigrate inside a Web Novel as a Side Character.

After wondering which door he must open first, Soma picks the massive door that first caught his sight. Slowly, he began to move his legs while the girls behind followed him like a duckling. The vast interior of the room makes the atmosphere surrounding the area feel eerie because of the mysterious ambiance it casts upon them.

While walking, Soma and the two keep their vigilance to the max, ready to draw their respective weapons anytime. However, so far, there is not a single threat that approached them.

Arriving at the huge door that stood five meters tall with intricate lining carved using skilled craft. The door itself was made from an unknown metal or material that gleamed in platinum. Even though the place looks desolate and ancient at the same time, the pillars, items and even this door manage to retain their glory without being eaten by the passage of time.

"How do we open it?".

"Hina is right. Is there some switch over here…?".

"Soma".

Xiao Lian, with her usual expressionless tone, stepped forward while showing the still-shining bracelet on her right wrist. Soma, who understood her meaning, nodded his head and let Xiao Lian do the rest. With a wave from her right hand, a blue spear emerged, emitting a strange blue glow as if it was thumping like a beating heart.

The massive gate, which seemed dormant for thousands of years, began to twitch and react to the strange light that radiated from the spear. The lining on the door's surface started to emit a faint blue light as Xiao Lian placed the spear tips on the ground.

Those massive doors, after receiving the signal from the spear, gradually began to let out a rumble because, for the first time in millennia, they moved. With its massive body, the area surrounding the door was also being affected, raising a cloud of dust that blocked the trio's sight.

Soma and the two girls raised their hands to block the dust that threatened their eyes. A faint trace of their foothold began to sway because of the tremor caused by the opened gate, making them alerted. Tensing all the muscles in their body, the door opened and showed a big enough gap for them to enter. Hina swiftly took out her Green Katana and held it in her left hand.

"You guys ready?".

After the dust had been cleared, Soma spoke his words and responded with a swift nod from the girls. Soma exhaled the breath he held earlier, then raised his first step to enter the space behind the massive door that seemed related to Dragon.

After the door opened, it fully exposed the space across. A sudden gust of pure mana that brightened their view stuck their body, invigorating their tired body after a tired walk. The three of them stood amazed as they enjoyed the exhilarating feeling that invaded their body.

After the storm of Mana passed, Soma resumed his pace and managed to pass the door that separated the two rooms, making Soma and the two girls' eyes wide open.

"What in the world?!".

"...Huge?!".

"...".

The interior of the room was massive with dome shapes, and in the middle of the room, there was an enormous pond filled with clear water that glittered in brilliant light because of the reflection from the transparent crystal above that acts as the sun.

The surrounding lake was a desolate ground, with blackened floors in every corner that still radiated some warmth as if it was still burned by the flame.

Soma scanned the surroundings and found nothing except the pond. As they walked toward the pond, the cold sensation that clashed with the warmth around him began to seep into their skin, making their body shudder slightly. The cold itself kept leaking from the water, creating a wonder that couldn't be solved by the kids.

However, when the trio arrived beside the pond lips, their bodies were stoned as they saw a massive skeletal figure of a coiling dragon that circled the lake perimeter as the testament of the ancient era, proofing that dragons really exist.

Its skeletal remains were weathered yet majestic with its antlers, the long yet flexible spine still whole and its four tiny legs that were sprawled across the pond bottom along with the glittering light of treasure, the remnant of the past.

"...Dragon, they exist".

Xiao Lian softly uttered those words as she bent her knees and neared her face toward the pond surface to see the real thing.

"What's wrong with her?".

Hina, oblivious to Xiao Lian circumstances, closed her distance with Soma with a soft whisper.

"...Wel, I don't know, but it seems she looks touched".

"..You are right".

As soon as Hina finished her words, Xiao Lian jerked her knee, standing up while hurriedly taking off her uniform. She threw away the blazer, loosening the red tie around her neck, and threw it to the floor too and when her finger reached her shirt button. Hina swiftly arrived before her and grabbed both Xiao Lian's hands, who wanted to continue further.

Xiao Lian met gaze with Hina, who knit her brows in displeasure. She, with an absentminded face, tilted her head and softly spoke.

"What are you doing?".

"That was supposed to be my line here. What are you doing?".

"I want to see the dragon skeleton more closely".

"...Then?".

"...then? ….if possible taking it with me to my home".

"Are you an idiot?".

"Hm?!".

Despite the disturbing words Xiao Lian had said. Soma faintly thought that it was actually a good plan. The bones of the Dragon would be a good material for crafting a weapon or even using it as a material for enhancing weapons, making it evolve a rank higher because of the high-class material. But should he do that?

"Please move, Red-hair!".

"I can't allow you butt naked here!".

The flickering of tiny bolts travels between the two girls' eyes. Before the situation worsened, Soma approached the two and put his hand on the girls' wrists, stiffening their faces.

"Calm down, you two. And Xiao Lian, I know you want to take a closer look at the fossil, but can you swim, or do you have the proper clothes for swimming?".

"...No".

Xiao Lian's flat tone resonated, making Hina's face blank in a dumbfounded state. Hina sighs with knitted brows holding her forehead, staring at Xiao Lian with a weird feeling in her chest.

"...Unbelievable. What is wrong with this girl?".

Hina let out her disbelieving words while watching Xiao Lian's figure tilted their head, looking at both of them flatly. Soma, who understands Hina's feelings, could only smile wryly because he is glad. After all, the person named Xiao Lian still had the same traits as in the novel he read. But at least there is one more question he needs to ask Xiao Lian just to be sure.

"...Xiao Lian, what makes you want to find dragon existence so badly?".

Soma noticed a slight ripple in her serene eyes. Xiao Lian loosened her tensed muscles, in which Hina also released her restraint. She cast her gaze downward while choosing her words to say to him.

"...I have my personal matters that I don't want to reveal. But at least I could tell you this…".

"...What is it?".

Soma took a step closer, trying to gauge her expression closely. Xiao Lian, who saw his silhouette, raised her gaze and met her eyes with Soma's calm and mysterious eyes. At times like this, she used to shift her mind and mute as she didn't want to talk anymore or reveal her circumstances to a stranger. But she didn't know why.

If she was currently with Soma, she felt that the boy before him was okay to know it even slightly.

"...I. I want to show it to my mother, who is currently sick and doesn't have much time in her life".

Hina gasped as her eyes bloated in silent shock while gazing at the Xiao Lian figure. Soma, on the other hand, closes his eyes, and with this, he is convicted and determined to help her at least a little. Besides, he is also curious about the treasure.

"...Okay, I will dive into the lake".

"Soma?".

"...Are you sure?".

Hina and Xiao Lian turned their heads simultaneously to Soma because of his absurd lines. Soma ignored the two gazes and shifted his gaze to the lake and saw the bottom of it, which had a depth of about five meters. With his current strength and control over his body, he felt confident he could hold his breath much longer compared to his previous lives.

"Don't worry, you can leave this to me".
