The puppet entered the box and moved out the iron furnace and other items.
Meanwhile, Li Yuan leaped into the box and took out several crystal stones.
These were his materials for forging soldiers — Upper Grade Blood Crystal Marrow.
This was also what he used for Gu Xuejian's weapon forging before.
You should know, for a normal Fifth Grade spiritual artifact forging, usually only "Blood Gold Crystal" is used, as "Blood Crystal Marrow" is exceedingly rare, and a whole "Blood Gold Vein" could take decades or even a century to produce a batch of such materials.
Blood Crystal Marrow is extremely dense, twice that of ordinary blood crystal, which is ten times that of iron.
As for the price, blood crystal compared to gold is entirely priceless, and blood crystal marrow compared to blood crystal is the same, but if forced to exchange, it would be one to three, in other words...a hundred pounds of Blood Crystal Marrow would be at least equivalent to three thousand taels of Blood Gold.
