Lol, how to complete this task?

If the visual field score reaches above 20, win a game.

The visual field score is a rough estimate of the contribution to the visual field competition, which can be roughly understood as "the guard survival/limit time I provide per minute is about 1 minute." The score is in the range of 5- 150.

So, if your vision score after the game is 12 1, you can probably know that "my vision contribution in this game is equivalent to the guard surviving for 2 hours." This figure mainly comes from three aspects:

The guard's life time provided: the guard you assigned will get 1 point for every minute of life (decimal may appear). This score will also be affected by many factors, see the "guard survival time coefficient" below.

Limit the guard's life time: When you exclude a guard (the person who won gold coins because the guard was destroyed), the remaining life time of this guard per minute will be increased by 1 point for you (the remaining life time of permanent guards is set to 5 minutes).

Visual mechanism: Different mechanisms that provide vision will have a benchmark score when used (usually between 1 and 0.5). If unknown heroes or epic monsters are exposed, they will get extra points (usually between 0. 1 and 1.0). This includes divining flowers, using decorations, setting guards, swift crabs in the canyon, Ash's eagle hitting the sky directly, calista's sentry and Quinn's keen perception. Eagle strikes the sky and detects that people on the opposite side are stealing dragons, which is much higher than Quinn's W score (but there will still be a certain score).

The average visual field score may range from single digits (short game time and insufficient use of accessories) to more than 100 (long game with continuous use of eye stones). Usually, the short game that pays attention to the field of vision has the highest score, and it is better to make full use of the long game assisted by the eye stone.
