Forging a "Qiankun" was a well-thought-out decision by Lu Yuan.
In fact, humans also have Qiankun, which is where the Extraordinary Spark is nurtured. Because of the existence of Qiankun, the Spark continues to grow and nourishes the body.
However, within the Greedy Demon God's "Qiankun" is not an Extraordinary Spark, but a small world capable of adjusting the speed of time's passage!
This small world is indestructible and can provide effects similar to the Extraordinary Spark.
It can also be used to suppress and seal those beings that cannot be killed.
Moreover, it can produce resources—after all, for the Greedy Demon God, "greed" is most important; if there are only inputs and no outputs, the cost-performance ratio is too low for a whole new organ.
"Qiankun is divided into Yin and Yang parts."
"The Yin part has a slow passage of time with temperatures nearing Absolute Zero."
