There are two types of the most advanced weapons in this world, one is the Solar Simulation Bomb, and the other is the Annihilation Cannon.
The explosion of the Solar Simulation Bomb can generate a temperature of hundreds of millions of degrees, similar to the temperature at the core of a nuclear explosion. Its advantage is that the temperature within the entire explosion range can reach hundreds of millions of degrees.
Humans have found that, compared to nuclear radiation, temperature poses a greater threat to ferocious beasts.
The Annihilation Cannon fires an invisible attack that decomposes anything it touches into atomic form. Its drawback is its difficulty to manufacture and large energy consumption.
If launched from a distance, the beasts will evade it, so these two types of weapons can only be used at close range.
