Before,I do as you asked I have a few questions regarding the technique,if it's ok with you.
1.So the object we repel,for example if it's a rock in front of us,still goes behind us?
2.This can repel the opponents techniques,right?
3.If so what happens to them,if for example the opponent sends some earth technique at us and we repel it,what will happen to that technique,same for water.
3.If we defend with this against the other three elements what happens to those techniques?
4.If it can repel techniques,up to what rank that is?
5.If it can repel water,does that water go behind us and then we can make it reappear where we want?
6.When we repel the boulder it can't come back earlier than 4 turns?I mean,I repel the boulder can I bring it back in the next turn?
7.Can this repel myself against the ground,as in the last exercise?
