In the Wilderness, Su Hao continued following his previous research rhythm—changing locations every so often and continuing his studies.
From time to time, he entered towns to rest and resupply.
He even once traveled to a major Human Race city—He'an Main City.

He had an idea: if he could find a material capable of restraining Blood Qi, then pre-engraving runes would no longer be a fantasy.
