The Wormhole Flower was the very one he had brought back from the Xiaohua Honghong Building, with its purple and red hues. When he brought it back, he didn't know what kind of flower it was, simply planting it out of curiosity. It was only on Deep Blue Island that Dr. Deng mentioned the name and use of the flower.
The amount of red on the Wormhole Flower's plant could display the evolutionary level of a game zone, akin to how players evolved due to environmental changes initially. As the environmental conditions of the zone change, the Wormhole Flower undergoes changes too. The higher the evolutionary level of the zone, the more red the Wormhole Flower shows.
Xu Huo was temporarily unclear about the source and direction of this evolution, but he was certain that the higher the level of evolution, the more integrated it would become with the game. Aside from humans and animals, everything in Zone 014, including above and below ground resources, would likely be affected.
