The high-quality material reserves of the alliance's high-rank mecha pilots come from those high-rank mecha pilots themselves.
In other words...
Big shots like Li Xiao are actually the biggest suppliers of high-rank, high-quality materials.
Under such circumstances, with tenfold burst rate privileges, one must fill Li Xiao's inventory to the brim, mustn't they?
Jiang Chen wished that whenever Li Xiao explored the abyss, even the most minor creatures he killed would explode with mythical materials!
As for those low-ranked mecha pilots...
Forget it.
Even if they had a hundred times the burst rate, wouldn't they still be waiting for Jiang Chen to feed them?
"It's a pity, there's an upper limit to the level of materials produced by the big shots."
"Given my growth rate, I will have to find my own way to produce top-notch materials in the future."
"I wonder how the hopefuls from other civilizations solve this problem?"
