The fourth Primordial Spirit Weapon that Wei Cheng intended to cultivate was still the Reflective Sky Lamp.
This indirectly allowed him to save a significant amount of time, after all, he had already cultivated the same lamp before.
The only thing he lacked was sufficient resources.
The three hundred strands of Immortal Spirit Qi he obtained this time perfectly compensated for this deficiency.
Three hundred strands might sound a little, but that's not the case.
A single strand of even the lowest quality Immortal Spirit Qi can support the needs of an average Cultivation World for a thousand years.
Theoretically speaking, a single strand of Immortal Spirit Qi can cultivate a Nine Tribulations Immortal of equal strength to Qi Mei.
Three hundred strands would equal three hundred Nine Tribulations Immortals.
Although this does not take into account the cost of time, it showcases the value of the hard currency that is Immortal Spirit Qi.
