Theories of the energy cannon were proposed eighteen years ago. Back then, it had created quite a global sensation. All countries in the world signed a petition boycotting the weapon.
It was too powerful, and once it was built, the end of the world would be inevitable. No country should be allowed to possess the weapon because the consequence would be too severe.
The ban had never been lifted.
As it turned out, Neige had been doing research on it in secret.
All coins had two sides. The energy cannon was formidable, but a single launch would also require an unimaginable amount of resources. It was equivalent to twenty times the national income of a country. Even Neige could only afford to fire it once.
A second launch would destroy the Neigerian economy. It was as if the cannonballs were made of money.
Ninety-three types of raw materials were needed to build an energy cannon, and each of them was more expensive than the next.
