"Experiment"
No wonder they only got one mission, which was to get the Acacia plant's roots but the mission level was A....
Of course, it could not be compared to the A+ mission to get an unknown monster's cub, but this mission was indeed more difficult than the B+ level mission to get the man-eating water lily that lived on the surface of the lake.
In short, there were those who had the mission to get the roots of the Acacia plants, another one needed the water lily, others had to get the Ballerina Plants, and two people needed the mysterious monster's cub.
Others didn't really need the monster's cub, but since they were all teammates, they had agreed to fetch all those items needed for the mission together as a whole.
Even if others in the team already got their share of the mission, they wouldn't be allowed to leave until all members of the team achieved their goals.
