As soon as the mysterious voice echoed, a wave of heat surged through Ling Han, as if every cell in his body was being reinforced.
In Ling Han's opinion, this wave of heat was similar to the sensation he experienced from taking strengthening pills before, but even more intense.
This was probably because the intensity of the sensation depends on how much his attributes improve.
"So, this is what it's like to level up?"
As soon as the sensation ended, which was extremely quick, the first thing Ling Han did was check his physique.
Although his body seemed the same as before, since all attributes had increased together, he couldn't help but get the impression that his strength had nearly doubled!
And it wasn't just an impression. Due to his abnormal evolution factor, amplified by the bonus from his class, his attributes jumped from 14 to 27 points.
'If it weren't for my class, with a normal evolution factor, I would need to reach at least level 5 to achieve these attributes!'
After checking his attribute points on the panel, Ling Han realized how advantageous his class bonus was.
He imagined that by the time he reached level 3, his attributes would be equivalent to, or even exceed, those of someone at level 10.
After coming back to his senses, Ling Han looked at the rusty sword with drops of blood in his hand and couldn't help but murmur, "Better than nothing."
After all, since it was impossible to bring a weapon to the Infinite Staircase, Ling Han hadn't bought a weapon and spent all his savings on strengthening pills, which were the only way to prepare for climbing the Infinite Staircase.
Now that he had the sword in hand and his strength practically doubled, Ling Han's confidence increased considerably.
And Ling Han's confidence was not exaggerated.
For in the following moments, the mysterious voice began to echo countless times in his mind.
[Ding, you killed a Skeleton Swordsman (No Rank)]
[Ding, you killed a Skeleton Archer (No Rank)]
[Ding, you killed a Skeleton (No Rank)]
...
In just a few minutes, the entire floor of the step was covered with pieces of skeleton bones.
"Now that I've evolved to level 1, these skeletons, which were already fragile, are nothing more than paper in front of me."
"Moreover, with the increase in spirit, I can see further through the mist."
Ling Han murmured to himself as he looked at the step where he had already killed all the skeletons, thinking that perhaps he shouldn't have killed the raven, which was an infinite source of skeletons.
This was because, even after eliminating all these skeletons, he still hadn't evolved to level 2.
'Forget it, time is short, and I need to climb as many steps as possible.'
As he looked at the time on the panel in front of him, which had already decreased to 3:44:07 and continued to decrease second by second, Ling Han couldn't help but feel a sense of urgency and walked toward the second step.
As for the difficulty of the next step, he wasn't worried.
He had learned in school that the difficulty between each step was not very large, gradually increasing rather than creating a huge gap.
However, this characteristic is advantageous for some but disadvantageous for others who wish to face more powerful monsters to level up more quickly.
Despite all these years since the Infinite Staircase appeared, no one has managed to discover exactly how the leveling system works or how many monsters need to be killed to level up.
Studies have shown that the number of monsters required to evolve varies from person to person.
In the end, it was decided that the system was too complex to be understood and depended on numerous factors.
The only confirmed discovery was that, when eliminating monsters of a lower rank than yours, no matter how many, it is impossible to level up. In contrast, killing monsters of a higher rank than yours allows for faster evolution
Of course, many people tried to bypass the system by having younger generations deal the final blow to rank A or rank S monsters to level up several levels in a row.
However, somehow, the confirmation message of the kill did not appear for those who killed monsters this way.
After getting out of his thoughts, Ling Han headed towards the second step of the Infinite Staircase.
The second step was not very different, at least not in terms of the environment.
The monsters were still skeletons, but this time they seemed to be wearing black armor, which considerably increased their defense but significantly decreased their speed.
However, in front of Ling Han, whose attributes had increased by 13 points, these skeletons couldn't even withstand a punch at his full strength.
The difference in strength between the skeletons of the two steps was not very large.
An example of this is that if it were possible to see the attributes of a skeleton from the first step, it would be noted that they had an average of 7 attribute points.
Now, if we compare that to a skeleton from the second step, their average attribute points would be around 7.7, while the physical attribute might reach 11 points.
Compared to Ling Han, who had increased 13 attribute points due to his evolution factor, this still represented a greater difference than that between him and the skeletons from the first step before leveling up!
This was also the reason Ling Han mentioned that, although at first there may not seem to be much difference, the higher he leveled up, the greater the impact of an abnormal evolution factor would be.
Unsurprisingly, as soon as he arrived at the second step, Ling Han felt like a butcher who had just entered a slaughterhouse.
