章 710: Formation Upgrade, Meeting Hu Kaiyun Again 1

The progress of the [Spirit Cultivation Technique] was quite smooth.

Wu Wei only took a day to finish it.

The initial estimate was that it would take about three months to complete.

However, this was only a preliminary estimate. Considering the increase in his [Spirit Nurturing Technique] and the increase in his [Lightning Manipulator] proficiency, Wu Wei believed that it would not take him three months to reach a million.

After all, 15 minutes was only their entry level. Once they were familiar with it, they should be able to reach 10 minutes like Wu Wei.

Although it was only a five-minute reduction, it could reduce the overall time by one-third or even less.

With the hope of engraving the [Backtrack Bead], Wu Wei's mood relaxed.

After settling everything, Wu Wei did not return to the Divine Talisman World to wait for time. Instead, he made good use of the remaining nine days in the Mystic Realm.
