When killing the three kings, after entering the first three kings battle, the team needs to control the battle rhythm. When there is only one NPC left in the first BOSS battle, the whole team except the captain should run away ( The captain escapes, and the system defaults to failure after the battle). This is when the captain on the field uses defense or medicine to delay time, and four people outside the field form a team to enter the second battle and kill the second BOSS. When the second BOSS died, the captain who was stalling for time in the first battle killed the last monster and joined the four people outside. This process takes up to 30 seconds, and then a team of 5 only needs to kill the third BOSS in 4 and a half minutes, so that the five-person dungeon of Black Chicken Kingdom can break through the bottleneck of "passing the three kings in five minutes"
