Skyrend Slash and Gale Chain Slash.

  These were still the only two skills he had—until he obtained more warrior class templates and fused them into his own unique warrior class template, these were all he could rely on.

  11 free attribute points.

  Lucas could distribute them separately, raising both skills to around level 7 or 8, or he could choose to max out one skill first before enhancing the other.

  But it seemed...

  There was no need to choose.

  Taking a deep breath in his mind, Lucas focused his attention on the skill Gale Chain Slash.

  Clearly, in the goal of hunting warrior skeletons, Gale Chain Slash played a more significant role than Skyrend Slash.

  1 free attribute point was consumed.

  The level of Gale Chain Slash increased from 5 to 6, further reducing its stamina consumption, and the total damage multiplier it unleashed also rose again.

  He continued to allocate points.

  A second free attribute point was consumed.

  Gale Chain Slash leveled up from 6 to 7.

  A third free attribute point was consumed.

  Gale Chain Slash leveled up from 7 to 8.

  After glancing at the skill description of Gale Chain Slash, which had been upgraded three times in a row, Lucas didn’t hesitate. He invested 2 more free attribute points into it, directly raising the skill to its maximum level of 10!

  At this point,

  the number of light blades unleashed by Gale Chain Slash reached twelve! The total damage caused by these twelve light blades was now twelve times that of a normal attack!

  An increase of nearly double!

  If Lucas were to face that Skeleton Commander again, a single burst from Gale Chain Slash would likely be enough to render it incapacitated.

  However...

  Looking at Gale Chain Slash, which he had now maxed out at level 10, Lucas felt a slight sense of confusion.

  The small "+" sign behind the skill did not disappear after reaching its maximum level. It still remained, as if suggesting that he could continue to invest free attribute points into Gale Chain Slash!

  He still had 6 free attribute points left.

  After a moment of contemplation, Lucas tentatively invested 1 more free attribute point into the already maxed-out Gale Chain Slash.

  It remained at level 10.

  The skill level didn’t change, and the description of Gale Chain Slash showed no alterations.

  "Not enough free attribute points invested?"

  The soul fire in his eye sockets flickered slightly, and Lucas invested another free attribute point into it.

  Still no change.

  "Perhaps..."

  After glancing at the remaining 4 free attribute points, Lucas invested again.

  3 points!

  4 points!

  5 points!

  When a total of 5 free attribute points were invested, the skill, which had already devoured 14 of Lucas’s free attribute points... finally underwent a change!

  The original skill disappeared.

  A brand-new skill appeared on Lucas’s attribute panel.

  Death Cleave: Active skill, an advanced version of Gale Chain Slash, non-upgradable. Consumes one-twentieth of stamina to instantly unleash ten light blades infused with the aura of death, delivering consecutive fatal strikes to the enemy, dealing a total of twenty times the damage of a normal attack.

  Death Cleave!

  A new skill had been born!

  And it was an advanced version of Gale Chain Slash!

  This tale has been pilfered from Royal Road. If found on Amazon, kindly file a report.

  Stamina consumption was reduced by half again, the number of light blades unleashed dropped from twelve to ten, and the total damage multiplier... skyrocketed from the original twelve times to a staggering twenty times!

  Especially...

  An advanced skill!

  With ten years of gaming experience from his past life, Lucas naturally understood the concept of advanced skills.

  Advanced skills were skills that evolved from their original versions. Not only did they consume less than their predecessors, but their power far surpassed that of the original skills!

  Another name players had for advanced skills was... BOSS skills!

  As the name suggests.

  BOSS skills were skills that only BOSSes could obtain.

  Among NPCs, only those who had stepped into the hero rank had a chance of possessing BOSS skills; among monsters, only entities like the Skeleton King, who had entered the lord rank, could possess BOSS skills!

  BOSSes, by definition, were what players called monsters of the lord rank and above.

  In his past life.

  BOSS skills, or advanced skills, had always been the object of players' pursuit. Their allure was no less than that of hidden classes, lost legacies, or even divine artifacts.

  However.

  By the time the gods descended and the world was destroyed, the number of players who had truly obtained advanced skills was less than ten!

  As a former legendary sword saint, Lucas hadn’t even managed to gather information on how to obtain advanced skills in his past life! It was as if advanced skills were truly only obtainable by monster BOSSes and hero NPCs!

  This alone demonstrated the rarity of advanced skills.

  And with rarity came immense power.

  It could be said that even the weakest advanced skill far surpassed the generic or class skills players could obtain through normal means.

  Death Cleave was an advanced skill.

  A BOSS skill.

  As Lucas looked at this skill, what came to mind wasn’t just this one skill.

  Death Cleave had been obtained by using free attribute points to max out Gale Chain Slash, a class skill, and then advancing it.

  Did that mean his other skill, Skyrend Slash, could also be maxed out and evolved into his second BOSS skill through the same method?

  And if he had enough free attribute points...

  Could all the skills he obtained in the future... be advanced into BOSS skills in this way?

  The reason BOSS monsters were called BOSSes was, first, because they had far superior four-dimensional attributes and health compared to players, NPCs, and ordinary monsters, making them extremely difficult to defeat.

  The second reason was that they possessed BOSS skills!

  These incredibly powerful BOSS skills allowed them to easily slaughter players of the same level or even higher, making soloing a BOSS an impossible task for players.

  Only after reaching a certain level and rank, and gathering enough players, could one dare to challenge a BOSS!

  Lucas smiled.

  Even though his skeletal face couldn’t physically form a smile, Lucas still smiled.

  Free attribute points.

  If his speculation was correct...

  With an endless supply of free attribute points, he could advance every skill he obtained in the future into a BOSS skill!

  If he had enough skills...

  The strongest BOSS in the history of the gaming world was about to be born!
