The third stage of the task was far more difficult than the other two stages combined. On the Beast King Island, all the creatures were Beast Kings. One could imagine what the final result would be when the Beast Kings appeared before them in packs.
A single Beast King was a huge threat to Mo Wen, let alone a pack of Beast Kings. If he was surrounded by a pack of Beast Kings, he would almost certainly perish.
As long as the Seven Human Warriors could survive in this space for a day, they would complete the task. However, surviving a day in such an environment was easier said than done. Even Mo Wen was not confident.
Fortunately, this task was not completely hopeless. All the human ancient martial art practitioners that died on this Beast King Island would not truly die. They would be revived in the space outside. However, once they died on this island, they would be withdrawn from the task.
