Shi Feng had already stayed in the Origin Sword Domain for three days now.
After killing a large number of Chieftain ranked Skeleton Giants and Blade Demons, the number of Legacy Chapters and Broken Steel Forging Design Fragments he could obtain from these two monsters had also reached its limit. No matter how many of these monsters Shi Feng killed, they no longer dropped any items.
If not for the fact that Shi Feng wanted to upgrade all his attack-type skills to Tier 1 skills and raise his current combat power to its utmost, he would have long since charged up Sword Peak Mountain.
Although he could still continue trying to upgrade the tier of his skills, the amount of Skill Proficiency required to raise a skill from Tier 1 to Tier 2 was simply too much. This was a feat that could not be accomplished within a short amount of time. In addition, Shi Feng did not have much time left.
