Five years ago.

"Kain, today is only your third day of hunting, right?"

The hunter took the rabbit from Kain's hand, asking him with uncertainty. To this, Kain only nodded lightly.

The hunter was still not too reassured, so the next day he went into the forest with Kain, to see how he hunted.

The results surprised the hunter.

It was seen that Kain was able to calculate almost exactly the distance and mobility of the rabbit based on the animal's running habits.

This is extremely terrifying in a way, because the prey's habits are something that can be grasped over time, but Kain can rely on that to know the prey's next move, with almost 100% accuracy.

Even a seasoned hunter can only stop at the level of "prediction", but for Kain, his senses are close to the level of "prediction".

What was even more astonishing was that Kain was only a ten-year-old boy at the time, a ten-year-old boy with incredibly sharp senses and observation.

Like a natural hunter.

…

In Kain's mind, a map of the four Tres' active locations hanging above his head quickly formed.

Even though he was surrounded, because Tres' range was limited to a circle, there were always gaps in the encirclement for him to move around.

However, these gaps do not always exist, but rather they appear in rotation. In order to utilize these things most smoothly, there is not a single second that Kain's mind does not calculate.

With these gaps, Kain continuously dodged Tres' attacks. Kain even experimented with using [Thunder Bullet] to kill one of the monsters.

The only thing is that the lightning damage to Tres isn't too bad, but it's not too good either.

Thunder has a contagious nature, but Tres's long, massive body is not only camouflaged by its protrusions but also by its giant roots, which is a kind of semi-counter to [Thunder Magic].

However, Kain was not too worried, because he had already calculated his own retreat route through observing the movements of the Tres.

Just as Kain was about to give up, a fireball came from nowhere and hit a Tres. This caused severe damage to the Tres's wooden body. The monster screamed with distorted sounds, its "branches" filled with teeth swaying nonstop.

[Fire Magic], the natural enemy of almost all monsters.

Kain turned around and found that the person who had just activated the magic skill was Myra.

[Fire Bullet], [Fire Wave].

A fireball hit Tres' head, followed by a wave of fire that rose and engulfed the monster.

Myra did not come alone.

Except for her, Mera also appeared.

Aside from the [Earth Magic] and [Air Magic] shown earlier, Mera also possessed [Fire Magic]. A total of three different magic systems, in a way, she was even more talented than her older sister.

Although Mera's [Fire Magic] couldn't compare to Myra's, dealing with these Tres wasn't that difficult.

Because their range of action was limited, the Tres were burned to death by the two sisters' fireballs, their entire long bodies becoming immobile, showing signs of being burned and destroyed by the small-range explosion.

"Thank you both."

Kain smiled and said, it seemed that his decision to form a team with others was correct. The diverse magic systems of the two sisters Myra and Mera truly filled the gap in area attack capabilities, high damage attack capabilities, and great destructive power. These were all factors that he lacked.

Kain still has weaknesses, and his teammates can compensate for these weaknesses very well.

"No problem, we just do our best."

"But wait, why did you two come here. You two should be resting at the campsite."

"This is what we were trying to say."

Myra's expression turned serious.

As it turned out, after Kain had left for quite some time to clear out the monsters around, a group of people had secretly approached the two sisters.

These people were all masked, to the point that their faces were covered by black cloth, leaving only their eyes exposed. These people seemed to have some evil intentions, fortunately the campsite that Kain had built was a place that was quite difficult to attack by surprise. Thanks to that, the two of them were able to escape successfully.

Hearing what Myra had to say, Kain said nothing but only frowned.

According to Myra's description, those people were not like Adventurers, they did not need to dress like that to enter the Dungeon. And if they were dressed like that, it showed that they did not want others to know their true identities.

"They are assassins, they are assassins."

Kain said.

Hearing this, both Myra and Mera looked confused. They felt confused not because of the "assassin", but because of "why is it an assassin".

The assassin shouldn't have appeared in this place, and shouldn't have targeted the two of them.

Kain did not explain further, just took out the cloths and gave them to Myra and Mera.

"From now on, we are forced to wear head coverings and cannot show our faces."

"Why?"

Mera asked again, but Kain did not answer, he only used a cloth to cover his own head. In the end, when all three people had their heads covered, coupled with the lack of strong light in the Dungeon, from a distance it was difficult to distinguish who was who.

At the same time, quite far away from Kain's team.

A young teenager who was also participating in the challenge was quickly approached by a group of masked assassins. An enemy appeared behind him, a knife directly stabbed him in the back.

The teenager was momentarily unable to react. But when he saw the assassin in front of him remove his mask, he became stunned, followed by a look of utter fear.

Because of the appearance of this mysterious group of forces, the already difficult challenge of conquering the Dungeon became even more dangerous.

Currently, there were only twenty people left who participated in the challenge.
