1. Kill the route first, starting from the camp dialogue, then the workshop will fight with familiar old friends (simple), take the shoal to the left grottoes to answer questions (random selection) and fight with old friends' rickshaws (simple), then take the shoal to talk with the lonely rock above, fight with materials between the corrupt lake and the night dew forest, go back to the lonely rock to get the medal, and return to the camp through the singularity. This time, you can see the first kill boss.
2. Actually, the boss is not difficult. It's not as difficult as the boss in the mini map. Hit the body is 100 poison. If you save beans before your second life, you are finished.
3. Try to kill the two boss things in the small map together. A boss is super simple. There are no other precautions. Nothing special, just a training map.
