Sanctuary: Safe Haven

Having studied Tonitrum's regimen and observed Canna's training, Mortem concluded. Although Canna hadn't yet realized it, Mortem could discern the signs. His daily routine, which involved slaying monsters, had conditioned his mind to view death as a natural phase and killing as common as breathing.

Tonitrum initially sneered at the undead, considering them mere entertainment. At first, he viewed Canna as a pet, much like how Canna would treat a dog. However, something shifted. He noticed a change in Canna's eyes each day, witnessing his gradual transformation into a skilled killer. During their encounter with the Thornstrider, Tonitrum saw it clearly—sparks of lightning.

Among the advanced elements, only time, space, light, darkness, and lightning proved the most challenging to control.

However, within just a few months, Canna managed to summon lightning, albeit accidentally. His training in water and wind spells was intended to prepare his body and mana for the eventual mastery of lightning. For Tonitrum, summoning lightning was not expected yet for several years.

So what's the connection with all of this about a Harbringer? Simple. According to legends, Harbingers have great affinities for elements that have pure destruction like fire, darkness, lightning and void.

Even though Canna only summoned it by mere accident, Tonitrum still took it to count since it showed early potential on casting lightning spells; another thing he considered was the fact that Canna took killing as a 'daily schedule', if it were a normal being there should still be a bit of psychological effect even a little but Canna showed nothing.

He looked at Mortem and spoke through telepathy, "Fu*k off," before going back to nap; in his head, plans started to conjure, he knew that Canna's soul was different, but he didn't expect it to be that different from the rest of the beings that came from different world as well.

At present, he was pondering how to create the most thrilling entertainment possible, unaware that the "entertainment" he was casually devising would become a formidable monster once unleashed outside the dungeon.

Usually, Canna would proceed with a mana application lesson with Mortem after waking up, but today, he decided to change his schedule.

Standing before the colossal 50-meter dragon head, he found himself in the company of Mortem, who cast a simple light spell to illuminate the dim surroundings.

He remembered a passage from the codex warning of dragons as embodiments of destruction and that one should flee as fast as possible at a sighting of one.

Based on the codex, there were only a handful of people who were able to get in touch with a dragon, and even then, no detailed reports were made, like how they take care of their scales, do they suffer from inherent health issues, is there any alternate diet rather than meat?

Canna knew for a fact that no living creature could be categorized as "perfect," and now he made a bold request to Tonitrum to know just that.

Tonitrum couldn't suppress a chuckle as he sensed Canna's thoughts, though he quickly reined in his amusement, aware that even his laughter alone could inflict pain on the boy and the undead duo.

Mortem, sensing the dragon's body vibrating, swiftly erected a powerful barrier between himself and Canna to shield them.

Despite Tonitrum's efforts to contain his laughter, it eventually burst forth, echoing through the dungeon. Mortem's barrier held for a mere three seconds before cracking sounds emerged. Desperately, Mortem poured more mana into the barrier, yet the cracks persisted. Canna joined in to reinforce it, but their combined efforts only extended its lifespan to ten seconds.

The barrier finally shattered, sending them both crashing into the dungeon walls.

Fortunately, Mortem managed to cast a protective shield for Canna but not for himself, resulting in black blood spilling from his mouth.

Luckily for Mortem, Tonitrum's laughter stops before he loses his life. The dragon looks at the duo and says, "Dragons are the apex of all species. Beings that can be compared to us can be counted on one hand. If we wished, the entire dragon race could unite and destroy this world. Fortunately for you, we don't need to, as it would be too troublesome."

"Now then, do as you wish," after giving his permission to Canna to do his "tests" on him, Tonitrum laid his head and closed his eyes, meanwhile the duo were still reeling in from the wounds they got from simple laughter from Tonitrum, Canna was the first one on his feet and after confirming that Mortem would be fine he quickly went to Tonitrum's side and summoned a water ball, he intended to wash the crimson scales of dragon and see if it would make the dragon feel good, next, he asked Tonitrum to open his mouth and examine the dragon's teeth Canna suspected that a tiny house could easily be built inside.

Upon closer inspection, Canna observed that every one of the dragon's teeth was filled with mana.

Tonitrum's mouth gaped wide, revealing a menacing array of long, jagged teeth arranged in rows. Some teeth curved inward, giving them a particularly irregular appearance.

It took half a day to complete his "tests." Canna meticulously examined Tonitrum's eyes, eyelids, ears, and nostrils, even daring to request that the dragon breathes in his direction. Throughout the process, Mortem watched in awe. This was a dragon imprisoned for its crazed for war, yet its master casually inspected its every feature, even knocking at the scales off its cheeks as if it were walls.

After completing the process, Tonitrum called for Canna, who was engrossed in writing on the codex. As Canna approached, a chill ran down his spine. Looking up, he was met with a menacing smile plastered on Tonitrum's face. The last time Canna had seen that smile, the dragon had summoned two trolls who nearly took his life. Setting the codex aside, Canna innocently asked, "Yes?"

"It's time to move up, I've been thinking of a way to make you grow stronger, and I got the best idea, pull up your stats and check your class"

Canna checks his stats, directing his attention to the category labeled "Class."
