He knocked a few times on the door until his supposed roommate woke up from her sleep. And fulfilling his exact expectations, she flared up in anger as soon as her eyes fell on him. "You, how did you get inside? Who are you?"
Looking at the girl who was ready to attack him, Sungjun introduced himself, "I'm Han Sungjun, your new roommate, Miss…"
His eyes wandered for a moment and then finished the sentence in an uncertain tone, "Sun Xiao?"
"You know my name?" She furrowed her brows.
"No, I guessed it." Sungjun shrugged his shoulders as he calmly pointed to a shelf where a backpack was placed. "I assume that is yours." On top of it lies the writing of her name, probably done by herself.
"Ah… I see." After taking a clear look at him, she gestured for him to come in.
As he went inside and sat on his bed, she asked, "Codename?"
"Still a probie," Sungjun replied with a straight face. "I haven't been awarded a codename yet."
"Probie?" She tilted her head in confusion as it appeared to be a new term for her.
"Probationary agent… a new recruit still in the training phase," Sungjun clarified to her before he asked her position.
His reply surprised the girl. She pointed her finger at him and hurled an insult, "You aren't even an official. Only a mere intern? You really have some guts to talk to me this way, boy. And by the way, who is that bastard who allowed you to share a room with me?"
A normal guy in his position wouldn't take an insult to his face when he wasn't even acquainted with the other party, but Sungjun didn't take it to his head and instead, he let out a chuckle in response, "Well, that bastard is Lieutenant Commander Cheng. You can go ahead and punish that lowly being for the mistake, but before that, at least, introduce yourself, Your Highness."
Sun Xiao felt as if she were being mocked by him. She flared up in anger once again. But with no justification to hit him, she forced herself to calm down and answered, or more like bragging about herself with hands on her back, "Sun Xiao, Title: Scarlet Flames, 22 years old; Rank-A with three years of experience in the field. Just so you know, I was a part of team SKY for 1 year, and I had a near 100% success rate last year. So, you should really know your place and stay here as if you don't exist, alright?"
"…" Sungjun really felt the urge to laugh out loud, seeing how immature she is. In the end, he played along with her, giving an elaborate gentleman bow, "Yes, Your Highness. Now, if you don't mind, I would like to take a rest."
"Hmpf, go on." She went back to her bed and continued to sleep.
Sungjun shook his head with a smile and sat on the bed in a lotus position.
'Mana Condensation'
"Before we go into this dungeon, I need to master this technique."
Shutting his eyes, Sungjun concentrated on his surroundings. "Okay, let's see… Hmm… two hundred meters? That seems right for the starters…"
He heightened his senses to atleast two hundred meters above, reaching the world outside the facility. Outside, there was nothing but a barren desert, stretching for dozens of miles in every direction.
From there, he started absorbing the natural energy. The absorbed energy entered his body, and then he simultaneously refined it into mana, slowly but steadily increasing his reserves.
As the distance is quite far and he is still a beginner, it took several minutes for a little bit of natural energy to even reach him, much less be absorbed into his body.
After several tries, he finally absorbed a minute amount of energy and proceeded with refining it.
Surprisingly, it was quickly refined in a smooth manner, just like how butter melts in hot oil.
As soon as the natural energy entered his body, he observed that his own mana energy rushed towards the invading objects and absorbed them instead of trying to repel them as a part of a defensive mechanism. "Perhaps it is due to the high compatibility," thought Sungjun.
Whatever the case, Sungjun was satisfied with the outcome and continued with Mana condensation, a high-ranking technique he accidentally found in a dungeon. It became smoother and smoother every time he received near-death injuries.
Just like that, several hours passed, and dawn arrived. Sungjun was immersed in his training.
As soon as the girl woke up in the morning after her 12 hours of sleep, she spotted her roommate. She rubbed her eyes and took a clear look at him again with her eyes wide open, "What was that?"
A faint glow of red aura formed a thin layer over his body.
