"The 'World Number' is something that, when you don't need to follow the rules to become an Immortal Emperor, and can plant it in nothingness, is simply a divine-term among the seven-colored terms."
However, the shortcomings are also obvious.
That is, it can only enhance cultivation; when cultivation reaches the Immortal Emperor, it has no impact on combat power.
There are still a thousand years until the awakening of the Heavenly Dao.
In such a long time, it is enough for him to elevate everyone in the Chao Tian Sect to Half-step Immortal Emperor. If the corresponding rules are arranged well, they would all be Immortal Emperors, but he wants to try, if with such cultivation he returns to Da Xia Country, and defeats the Divination Transformation Puppet, it would still count as breaking out of Heavenly Prison.
If it counts.
Then there wouldn't even be a need for rules; they would all be Immortal Emperors.
