It has already been four months, or close to four months, since Klaus entered the dungeon. It has also been over a month since he completed the last trial, leaving him deep within the sea with a huge hold through his chest.
However, many things were happening outside while he was submerged in the sea.
Four weeks ago, Lucy led Klaus's friends and her fellow sisters to the Tier 7 Forbidden Realm after spending close to three weeks there.
While it was a major undertaking, they didn't return the same. A few days after their return, Lucy broke through to the Great Sage stage, making her become several times stronger...
She received some skills and made tremendous progress in both her ice and wood elemental cultivation.
If Klaus had been present, he would have associated her wood element with the thick hairs of the alien-looking demon he had killed when Oscar, the half-demon, summoned it using the Seven Deadly Cards.
