From the sixth level of the Undersea Divine Palace, to reach the fifteenth level, one must cross eight levels, including the eleventh level.
God King Hei Mei had previously warned that within the Undersea Divine Palace's thirty-three levels, every eleven levels represent a tier of difficulty.
Once one surpassed the eleventh level, for a Heavenly Saint Realm warrior, it was absolutely impossible to set foot there without full reliance.
In the previous levels, although there were dangers of True God level, those were after all a minority of realms.
As long as one didn't meticulously search every single realm and carefully avoided the True God-level dangers, there was still hope for a Heavenly Saint Realm warrior to survive.
However, from the words of God King Hei Mei, it was clear that after passing the eleventh level, even with great care, a Heavenly Saint Realm warrior would most likely be doomed.
That place was almost reserved for True Gods to enter.
