It was said that was started in africa for the first time in the world. have you ever observed? in old films, the gods used to touch the arrow to their head and recite the mantra before aiming the arrow. Then they shoot the arrow. Then the arrow evolves as the different enegies in its travelling and attacks the enemy. What the thing happening here is...

I will tell you what they said in next part tnq for reading
