Zhang Yanhang woke up very early this morning, around five o'clock. After wasting some time making choices and eating, he started his research at six in the morning and had been engaged in it all morning.
His six hours of research did indeed yield some useful findings. For instance, he ascertained that the exoskeleton, mouthparts, and most organs of the Crimson Iron Ants were of little use to him. Although he managed to craft some white quality equipment, what he needed was higher quality gear.
Well, perhaps knowing these things couldn't really be considered a discovery. Zhang Yanhang's real gain was the Ant Acid of the Crimson Iron Ants; he found that the corrosive power of this substance was unexpectedly strong.
Even aqua regia, renowned for dissolving metals, needed several minutes to soften them to some degree, whereas Ant Acid from Crimson Iron Ants? Sprayed onto Crimson Iron Ore, it barely took a few seconds to soften it to an edible consistency.
