The most important part of a plant was its roots.
Many old trees with their trunks cut off, would still be able to sprout in the end. But if there were something wrong with their roots, they would not be able to live for long. This was true for the mutated plants in the Overseas Islands. Whether it was a man-eating flower or a man-eating tree, or other mutated plants that were not well known, their core weakness was their roots. Even if the things on the surface of the ground were cut off, they would still regrow within a short amount of time.
When plants have mutated to this extent, they were almost like animals!
Although they did not have the intelligence of animals, they would have relied on their original instincts. This area should be one of the places left ravaged by the disaster previously.
