I want to invent a new type of military weapon.

I want to invent a new type of military weapon with incomparable power. Its bullet is only one nanometer, but its power can blow up a planet. The bullets of this kind of weapon are made of air. They are very environmentally friendly. After the explosion, they will generate more than 1 million tons of oxygen. When the earth cannot use it, they can be launched on the moon and Mars. When the energy on the earth is to be When we are exhausted, we are good at the moon and Mars to develop the space for our human existence. Although I still have no ability to make such weapons, I will study science and culture knowledge well. In the future, I will invent this military weapon to protect our beautiful homeland.
