My idea

Our group member were getting crazy for this story because the power of the cult is not strong enough, so we are constantly to change to make it be more powerful. We got a lot of ideas but its too much and always feel not good enough ! Now , I share my idea here , hope Mr Charles can give us some suggestion .

My idea 1 ：

A and B are a scientist . They also a love environmentally friendly people . They feel that gasoline is the most serious cause of damage the earth, so they never have any use of gasoline from vehicles and they just walk or ride a bicycle.
They always try to intend to manufacture a vehicle is to not use gasoline ! B read a sentence that a person's blood can produce power in a old book . However , they never success because the blood is not enough to produce power .

One day, they ride to back home, A  found C collapsed on the floor . Then they rescued him and brought home. When C wake up then first see A, she attracted to him. C thought only A in the house . So he was ready to rape A but B hit him to dizzy with a rod.

After, C tied up.

A and B decided to use the blood of the bad guys to create a vehicle which never use gasoline !
