Qi Cultivation at the eighth or ninth level is considered to be legendary, and Foundation Establishment Stage practitioners are treated as Immortals descending to the mortal realm.
For the Foundation Establishment Stage practitioners trapped in the lower planes of the Nine Continents, this secret realm is as wonderful as a dream.
With countless beauties throwing themselves at them, so-called Grandmaster Realm opponents are unable to withstand a single blow, there are massive amounts of heavenly treasures and natural resources to help them ascend to the Nascent Soul stage, and they are able to establish countries and enjoy royal majesty.
To put it accurately, it's beyond even their wildest dreams.
These things didn't have much attraction for Jiang Li, but he roughly guessed what the secret realm wanted to test. Out of respect for his seniors, he still acted according to the desires of the secret realm.
