To Tang Zhen, every place was a place for cultivation. There was no need for him to specially choose a paradise.
However, the sect beneath his feet was indeed a blessed land. Before the catastrophe, it was a true forbidden land for mortals.
Heavenly paradises were the most sought after places for cultivators, and this was especially true for the large sects. They would try to seize them at all costs.
Once they successfully obtained it, they would do their best to protect it.
No matter how much you invested, you wouldn't suffer a loss. Grotto-heavens and blessed lands could feed cultivators in return, and were the best breeding ground for a ten-thousand-year-old sect.
In order to maximize the value of the Blessed land, a corresponding formation must be set up to fully display the effect of cultivation.
If it couldn't be done, the grotto-heavens and blessed lands would become ordinary.
