How to save Dian Wei in the escape battle of Wei City in the origin of Dynasty Warriors
Rescue Dian Wei and escape from Weicheng
Once the battle begins, head to the northwest base and capture it, cross the river and defeat the enemy general here. This would provide access for subsequent siege echelons. After completing this, quickly move across the battlefield and capture the base to the northeast. Both bases must be captured in order for the echelon to appear. Although the echelon comes from the west, it is faster to capture the western base first and then the eastern base.
You need to capture both bases within four minutes to keep progress. Then return to the center of the map and defeat the ambushed enemy generals coming from below the northwest base, as well as all the enemy generals concentrated in the center of the map. Your allies will help, but you have about two minutes to complete the task. At some point, a siege echelon will appear - even if the central area isn't cleared, you should head to the echelon immediately. However, if the central area is clear, the next part will be easier.
When the siege team has set up the ladder (you should cross the river immediately after the ladder is set up), you need to enter Wei City and defeat Zhang Xiu, Jia Xu and Zhang Quan. Zhang Xiu will usually run outside the city, which is why it's crucial to clear the central area ahead of time (thus allowing more allies to help weaken him or prevent him from escaping too far). You might consider dealing with Zhang Xiu first, but the other two generals are clustered together at first, so using a good AoE, Tactics, or Musou attack can do a lot of damage. No matter how you do it, you'll need to complete this section in about two minutes to complete the task in eight minutes total.
After completing this, continue deeper into the city and defeat Hu Cheer. You should complete this task within two minutes, which means the entire mission needs to be completed within ten minutes. If he mentions that you saved Cao Cao's guard, that proves you did it in time. If not, you're late and need to start over. When he is defeated, Dian Wei should mention that the number of enemy troops has decreased. If he doesn't mention it (but Hu Che'er does mention guards), that means you took too long to defeat Hu Che'er. At this point, you need to restart the mission. If Dian Wei made this comment, then escape with Cao Cao and you have completed part of the true ending.
