Cain frowned as he saw the scarcity of his Essence Cultivation Technique. All those he obtained in Kronos could only unleash power at the bottom of the Apotheosis Realm. The only reason the Demonic Phantom could stand against a Bone Tribulation Master was due to the Radiance of Life and Radiance of Strength improving it.
It was time to improve it, but Cain did not have better techniques. The ones he obtained from Sabina's space ring were focused only on the Law of Blood, and none surpassed the Apotheosis Realm.
The woman was a Divine Ascension Master, and Cain expected her to have some techniques of that level, but he was out of luck. Most likely, she did not own her cultivation technique and trained in a special ground of the Tier 0 Dark Faction Blood Path, or else there would be a star gem of the art among the stolen belongings.
