It took a month to travel from Sword Demon Mountain to Chaos Island, and during this time, Jiang Han was mostly in seclusion.

His cultivation had reached the ninth level of the Mountain and Sea, but he couldn't construct the Divine Altar and had to find a way to break through to the Samsara Realm. To do so, he first needed to open the secret realm of reincarnation.

This was a formidable barrier. As martial arts cultivation progressed, opening new secret realms became increasingly difficult.

Lin Ye and the other three were all at the ninth level of the Mountain and Sea, with two of them estimated to be in their fifties or sixties, likely stuck at this stage for many years.
