So, although Chaos Crystals were important, the Chaos Origin was the foundation of everything. With enough Chaos Crystals, even a pig could reach Spirit Transformation. However, the amount of Chaos Crystals needed to push an ordinary pig from the mortal world to that level would be astronomical.
Take Lei Dong's above-average aptitude, for example. Reaching the peak of Nascent Soul level was already an incredible achievement. Everything he had gone through was beyond the imagining of someone as exceptionally gifted as Dongfang Fu. To advance further would take several times the resources Dongfang Fu needed—perhaps even ten times as much. The higher one climbed, the greater the gap became.
And if one's level of life was high enough, perhaps one could advance without needing Chaos Crystals at all.
Besides, with Lei Dong's wretched aptitude, he could still reach his current level by piling on vast amounts of resources. But what about later? What if he wanted to become a Supreme? By then, even pouring all the world's resources into Lei Dong might not be enough to make that wish come true.
With the Chaos Origin in hand, however, anything was possible.
After encouraging his subordinates for a while, Lei Dong decided not to waste the Cave Heaven Blessed Land, which was still open. He gathered his followers and began cultivating in seclusion. At the same time, most of the Fierce Ghost Army and Hidden Dragon Army were sent into the Cave Heaven Blessed Land to cultivate with all their might.
The remaining soldiers, along with the Heavenly Demons, Wan Yan, and the others, helped Lei Dong set up more Chaos Spirit Gathering Formations throughout this Chaos dimension and gather resources on a grand scale. They also began clearing out the mining teams the Lord of the Abyss had left behind
