Backtrack Tool, Spirit Essence Formation Disk 1

Hundred Schools, Level C Secret Realm Management Center.

Wu Wei came out of the Eastern Han's Source Secret Realm with two scrolls in his hands.

One was the [God Weapon Talisman Upgrade Scroll], and the other was the [Item Upgrade Scroll].

Yes, the two cards that Wu Wei had just used.

The reason why the item that had already been used would still appear in Wu Wei's hands was all thanks to the [Backtrack Pearl].

In fact, Wu Wei had a bold idea when he saw the two scrolls.

Since the [Pushing Back Diagram Manuscript], which was also a consumable item, could be used repeatedly with the help of the [Backtrack Power], could the [Divine Talisman Upgrade Scroll] and the [Item Upgrade Scroll], which were also consumable items, be used repeatedly?

This idea was very bold, but once it succeeded, there would be a terrifying amount of production.

Therefore, Wu Wei did an experiment.
