For him, if he wants to quickly improve his strength, then cultivation resources are essential.
Especially at this important checkpoint.
Currently, the biggest limit for him is the accumulation of his progress in cultivation.
For the foundation of the Cave Realm, he already has information pertaining to the seeds of the World Tree.
If all goes well, he will be able to enter the ruins of the Ancient Heavenly Court to obtain the seeds of this World Tree in two months.
Using the World Tree seeds as the foundation, he will be able to open up the Cave Realm, and the origin of the Cave will become even more profound.
Moreover, for the vast majority of the heaven geniuses, the most challenging aspect of breakthrough to the Cave Realm is mastering the rules of space.
However, he already possesses this element.
So his biggest limitation remains the accumulation of cultivation resources.
