Back when the Kyushu Group was expanding towards the Northwest Region, it encountered a conflict with the Southwest Song Family due to the jewelry industry infringing on the Song Family's core interests.
At that time, the jade mines in the Southwest Border of Mian Country were controlled by three jade warlords: General Anthony, Marshal Marha, and General Duola.
The Song Family had good connections with General Anthony and Marshal Marha, acquiring a substantial share of raw jade stones from them, perfectly sustaining their Northwest business.
Later, Chen Tang directly established contact with General Duola and conveniently helped General Duola annex Anthony and Marha.
This led to the entire Southwest Border Region of Huaya completely being under General Duola's control. This area, originally unmanaged, ultimately achieved complete unity. General Duola's strength grew so formidable that it could vaguely contend with Mian Country's official forces.
