Centipede buys a lot of shoes. How to write a 400-word composition?

One day I saw a bug on TV, and later I learned that it was called centipede through introduction. The centipede on TV is reddish brown and has countless feet.

One day, I found a centipede preying on an earthworm in the grass. It first touched the earthworm with its tentacles, but the earthworm did not move, so the centipede quickly climbed onto the earthworm and ate it with relish. I wonder why the centipede touches the earthworm with its tentacles and the earthworm doesn't move. With so many centipede feet, it should be very troublesome to cooperate. How can they walk so fast? I go home with these questions.

When I get home, I will go to Baidu immediately. Com to search, and finally found a satisfactory answer. It turns out that centipede's tentacles can paralyze each other, and centipede's feet walk very fast like two feet, so I suddenly thought: if only I could invent a kind of shoes. This pair of shoes is made of steel. The shoes are divided into two layers, and there is a simulated plastic centipede on the lower layer. There are dozens of holes in the soles of centipedes' feet for feet and tentacles. As long as the electricity is enough, the centipede starts to run, and a dozen feet start to climb, which is several times faster than ordinary shoes. For example, take one step with ordinary shoes and three steps with centipede shoes. These centipede shoes can also prevent bad people. If you meet a bad guy, just press the green button on your shoes, and the centipede's tentacles will release toxins and paralyze the bad guy. If I become a scientist in the future, my first invention must be this pair of centipede shoes for the benefit of mankind.
