Theoretically speaking, for Lu Li and Leng Wuxin to fly on the lotus at the top of its speed, they would arrive at the portal to the Central Imperial Universe in about 10 days.
That lotus could travel at a speed comparable to an Earth Immortal Realm warrior while Lu Li could only be as fast as a Human Sovereign Realm warrior at the middle stage. It would cost him more than half a month, then, to fly over in a straight line.
However—Lu Li could not swagger around and fly in a straight line even though Leng Wuxin had told him the Beasts of Primordial Chaos in the Prison of Gold would not attack him. That being said, there were many warriors hiding in cultivation in the Prison of Gold. It was possible that Lu Li would run into the powerful ones and him being arrogant might cost his own life.
