Chu Ming's trip to the Treasure Pavilion had two purposes: one was to use contribution points to exchange for a treasure sword, and the other was to select a high-tier Earth Level swordsmanship martial technique. Chu Ming had already created the fifth technique of "Extreme Point Swordsmanship" and cultivated it to the stage of mastery. However, creating the sixth technique posed a great challenge, akin to creating an entirely new martial technique, which was beyond Chu Ming's current comprehension.
Thus, selecting a high-tier Earth Level swordsmanship martial technique was of utmost importance. As for the treasure sword, Chu Ming discovered during his battles with the corpse puppets that his sword was a weakness.
The Blue Red Sword was merely a middle-tier Profound Level treasure sword, which sufficed during Chu Ming's Transcendence Realm stage, but now it proved somewhat inadequate.
