This plant laboratory is located in the basement of New Shopping Mall, which is a very unexpected location. Judging from its internal devices, it is most likely a space transformed from an underground garage. Similarly, this space can also be reached by riding the roller coaster inside New Shopping Mall.

When Wanderer arrived, there was no one in the Plant Laboratory. Most of the equipment looked abandoned for a long time and was covered with vines. However, some equipment, such as computers, seemed to be still in use but was also covered with dust. The objects of Laboratory research are obviously plants. Based on Wanderer's observations, she believes that these plants come from the Forest City in the Lost City.
