 ## Next Steps
 
-1. Continue from Dingjun Mountain into the Hanzhong decisive battle, using Huang Zhong/Fa Zheng and Wang Ping's terrain knowledge as the tactical axis
-2. Add the formal Shu-Han foundation setup once Hanzhong's military basis is strong enough
+1. Continue from Hanzhong victory into the King of Hanzhong and Shu-Han foundation setup, making the political transition playable in camp rather than a single text page
+2. Add the next tension around Guan Yu's Jing Province defense so the Shu-Han foundation has an immediate strategic cost
 3. Expand sortie selection into richer pre-battle officer planning, including explicit reserve drills, class practice, and bond-focused camp assignments
 4. Add a dedicated treasure/equipment management view so players can compare special effects and growth
 5. Keep expanding scenarios through the long campaign instead of treating the current slice as an ending
