On the map, go to the old southern part of the map. Clear out all the minions except the cannon, leaving only one cannon.
Then use the command set to pull the NPCs into a straight line, and let the cannons slowly hit the corners one by one. They cannot be hit up the stairs...If they are hit up the stairs, they cannot be shot at 3 people
It is recommended to use a big move first. Since the healing wide-area bullet has the effect of increasing the skill slot, it is relatively safe for the AED to save NPCs under the cannon. After using the big move, we can start our rescue cycle.
Predict the timing of the cannon's launch and use the foundation stone to hide. The AED bullets need to be placed on the gun before each cannon is fired. Once the cannon is fired, fire the AED immediately and then manually resurrect and wait for the next round
When the ultimate skill is almost over, the ultimate gauge is almost full. If it is just a little bit short, you can go under the cannon and shoot a healing wide-area bullet. When it is full, continue again
Basically, if you stand in the middle of the NPCs and just focus on AED bombs, cornerstones, manual rescues, and ultimate moves, there will be no problem
