However, the Heaven-Reaching Spirit Pill has a unique function that other pills don't: it can temporarily be stored in the Dantian!
Whenever your spiritual power is depleted, it automatically replenishes itself, whereas with other pills, you still have to consume them.
Moreover, during the most intense battles, you might not even have the time to consume them, leading to spiritual power depletion, exposing a flaw, and ultimately being defeated!
And most importantly, the production cost is high. For other pills, one batch can yield at least eighty to a hundred pills, and the refining cycle is short. The slowest among them takes only one week. Of course, even the actual refining time for the Heaven-Reaching Spirit Pill doesn't exceed a year, but it takes eight months to produce the Heaven-Reaching Spirit Pill!
You can imagine how low the cost-effectiveness of the Heaven-Reaching Spirit Pill is.
