Gu Chen had considered that, now as the acting Warden of the Jing Tian Department in Youzhou, with jurisdiction over an entire region, he had ample resources at his disposal to search for a soul crystal.
However, there were several points that Gu Chen had to consider.
The first point was that soul crystals are extremely precious and not commonplace. They have many uses, and not only did Gu Chen need them, but other commanders of the Jing Tian Department, as well as alchemists and weapon refiners, also required them.
The Jing Tian Department explicitly stated that whoever killed the demon-like creatures would own their soul crystals. Should he ask the whole of Youzhou to help him search for soul crystals, it would be tantamount to taking benefits from the hands of these martial artists of the Jing Tian Department, seizing their spoils of war, which may lead to dissatisfaction among some.
