Han Yuan had once taken several turns around Dong Hao City and discovered something.
Dong Hao City did not have any top-tier grounds for tempering one's will.
The highest-grade will-tempering ground he could find was only effective for those in the middle stage of the Creation Dao Realm. By the late stage of the Creation Dao Realm, it had little tempering effect.
In theory, the Dong Hao Lord could create will-type treasures effective even on those at the perfected Creation Dao Realm. Yet he had not made them.
