Chen Fan generated electronic manuals for over a dozen immortal arts he had created in one go, then had the Immortal Net assistant sprite upload them to the various immortal art trading platforms.
They had all evolved from the supreme divine abilities he had created back when he was the Celestial Emperor. Now, these immortal arts offered him only negligible help, so he might as well package them up and sell them.
The Immortal Net assistant sprite assessed his eighteen electronic immortal art manuals. Six had reached the level of mid-grade immortal arts, while twelve were low-grade immortal arts. All of them had entered the ranks.
Low-grade immortal arts corresponded to Human Immortals, mid-grade immortal arts to Earth Immortals, high-grade immortal arts to Heaven Immortals, and supreme-grade immortal arts to True Immortals. Supreme-grade immortal arts were also called True Immortal-level immortal arts.
Beyond those were Immortal King-level immortal arts and Immortal Emperor-level immortal arts. Such arts were also openly sold on the Immortal Net, but every single one came with an astronomical price tag. Besides, immortals of ordinary aptitude would be wasting their money even if they bought them—they simply could not master them.
Although low-grade immortal arts were used by Human Immortals, their creators had to be at least Earth Immortals, or even Heaven Immortals.
And while mid-grade immortal arts were mainly used by Earth Immortals, their creators had to be at least Heaven Immortals. Some True Immortals could only create one or two mid-grade immortal arts in their entire lives.
The difficulty of cultivating an immortal art and creating one could not be mentioned in the same breath.
For Chen Fan, at the peak of the Earth Immortal realm, to create six mid-grade immortal arts and twelve low-grade immortal arts made him more prolific than the overwhelming majority
