Is there a question or statement in there somewhere? I have no earthly idea what you are asking. I caught bullet king. He's the boss at the top of the map, to the left of the dark zone entrance. If you kill him, he'll respawn in 4 hours for you. Multiple characters can run all bosses independently of either other.
Step 1. Fast Travel to Autumn's Hope Safe House.
Step 2. Exit Safe House and turn to your right.
Step 3. Turn left once on the street and go towards garbage truck.
Step 4. Waste Bullet King and his entourage of 3 or 4 that are in front of garbage truck or around intersection directly ahead.
Step 5. Wait 4 hours.
Step 6. Repeat, as needed.
