In this special illusion realm, Chen Fei killed every origin demon with only a single move, so killing origin demons did not actually take much time.

After all, this secret realm was not under Chen Fei's control. He merely observed the operation of the Heavenly Dao, found a suitable point of entry, and then entered the secret realms of other origin demons.

But since he was borrowing it, he could not act entirely as he pleased. To avoid the backlash of the Secret Realm Heavenly Dao, Chen Fei did not dare go too far.
Thus, spending several breaths to kill one origin demon was inevitable. And Chen Fei did not specifically choose late Eleventh Order origin demons to kill, instead selecting those closest to him.
The closer they were, the less time it took. If Chen Fei deliberately sought out late Eleventh Order origin demons, he first had to locate them, then search across great distances for a gap in the illusion realm, and only then could he borrow the Space Heavenly Dao.
What consumed the most time was actually long-distance spatial jumping. This was not teleportation; it was merely far faster than Chen Fei's normal flight.
At its shortest, it still took several breaths. At its longest, even twenty or thirty breaths would not be enough. By then, Chen Fei would not be
