Follow your dreams

You decide to go to check the tree you saw in your dream.

Your foot still hurts, but you have no problems with walking.

You reach the huge oak you saw on your dream, and just when you are looking around you hear a charming voice.

"Come forth my little friend, I won't harm you."

You see the oak moving, and a part of it takes the shape of a woman and comes out of the tree.

"I need your help, and if you help me I will reward you too." she continues.

"Listen, I know that your tribe hates humans. I need you to ask your tribe to kill some humans that came in the forest recently. They aren't warriors, only one of them is." she explains.

"But why do you care for some humans?" you ask.

"They rested close to my area and I heard them talking. They have found a possible good location for a mine at the hills." she speaks with a soft voice.

"If they indeed find such a thing, more humans will come. They will start cutting more trees, maybe even create a new village here or even open a road in the forest." they have to be stopped.

"I can't leave my tree and I can't fight them, but they won't be a problem for you..."

"You are right, we can't allow this to happen, but I can't go back to my village now. Is there any other way?" you ask.

She pauses for a while, and then she replies.

"Well, if you could go to kill them alone, I could ask some of my friends to help you, but they aren't warriors, and you have to make sure that they won't die."

"Hmmm...you said something about a reward?" you ask her. It isn't that you are greedy, but you are.

"If you manage to kill them and you bring their heads as a proof I will do you...anything within my abilities" she says suggestively.

"They are 5 weak looking humans and 1 warrior"

What do you do?
1 Try to ask for a better reward (if you fail she will probably be a bit less friendly with you in the future, if you know what I mean)
2 Go alone (harder but she will be impressed if you pull it off)
3 Ask for help from her friends
4 Return to the village, surely they won't remove you from the competition since there is an important reason.
5 Decline, you can solve the problem later
