Combining benevolence with authority has always been the truth in managing subordinates. The battle at Hexi crushed Hei Miao, and the second battle settled Nanjiang, striking fear into the Wu Miao coalition; this is authority. Using Hong Ju and his son to rule over Nanjiang provided a chance for reconciliation, and further implementing new policies at Hexi to improve the lives of the Wu Miao people; this is benevolence.
In the short term, the people of Nanjiang might not feel it, but over time, they will naturally come together with Hexi. Hou Yuduan's previous proposals are absolutely up to the test, and Hou Yuxiao can confirm this.
The only uncertainty lies with Hong Ju and his son!
After the battle of Nanjiang, the Hong Miao's losses were relatively minimal. Hong Ju, the Sub-Saint of Martial Dao, remains, with the Hong Miao tribe still having over two hundred thousand troops and two powerful figures at the shattered realm. Such strength makes Hou Yuxiao wary.
