Eternal Tower, each level is more difficult to break through than the last.
For Ninth Rank cultivators, passing the first level means they are a genius in the universe, representing the ability to conquer oneself and break through limits.
Passing the second level allows one to boast in the outer regions of the Star Ruins Realm.
The geniuses brought by Jiuyu Commerce Alliance can actually only pass the third level.
Those who can pass the fourth level are considered highly talented and perceptive geniuses in the inner circle of the Star Ruins Realm, able to join the Trading Building of the base and enter various star ruins secret places for better comprehension of laws.
Passing the fourth level means this genius is stable enough to advance to the Tenth Rank, and can go far within the Tenth Rank, even reaching the Eleventh Rank.
