In that way, due to a slight delay, the three beastmen had closed the distance between them and the elves. By the time the elves responded, they had lost their distance advantage over the three beastmen. It was not a question of the elves being match for the beastmen at close range. Even if the three beastmen did not attack them, the elves would find it difficult to prevent their actions due to the proximity of the beastmen.
In fact, the situation was indeed like this at the time.
According to the elves' initial plan, no matter what, the three beastmen wouldn't have been able to escape with their lives. Even if Zhou Tian couldn't kill the three beastmen, a final blow from the elves could easily finish them off after.
