Finally, by the combination attack they have already killed all those poisonous snakes and after that they decided to change the place as best they can. First of all, the blood of those snakes will naturally attract the attention of other Monsters and also they did not know if those snakes call for reinforcement or not.
Even though they had the antidote, they still wanted to avoid being affected by the poison so naturally they wanted to change their position as quickly as they could. Fortunately after that they already find out no snake Monsters coming after them and with that they decided to recover that lost Energy.
This time it did not take them that much time to recover theri full energy. But none of them care about them as they are thinking what to do to find those water lizards that will give them the location of those water heart fruits.
