Earlier he had calculated carefully, counting the Luck Holy Blood in the cloned [Blood Holy Grail], including Ninth Rank Dominant Origin Blood, Eighth Rank Blood of the Evil God, as well as Chaos Blood Organ and Chaos Demon Ape Spirit Bone, the upgrade success rate of the Heavenly Ruins Cang Qiong was just over 50%.
He must ensure that all special resources are gathered, plus one or two extra upgrade resources, to raise the success rate over 80%. Thus, adding the Seventh Rank [Time Realm Fruit], this success rate would be quite promising.
Of course, even if the Seventh Rank [Time Realm Fruit] fails, he still has the "Time·Retrospect" feature of the [Time Chessboard], which can allow the Heavenly Ruins Cang Qiong to return to ten seconds earlier, equivalent to holding four chances of impact, making failure nearly impossible.
