MTL-The sword is the truth

Synopsis

Insufficient evidence and firepower to join in! Truth is everywhere within range! For example, if you want to reason with that Golden Core cultivator, you can take this 200 billion-ton hydrogen bomb with you. If your opponent is a big sect, I suggest you buy a meteorite that has accelerated to [-] kilometers per second and has a diameter of ten kilometers, and aim it at his sect. They will definitely hope that you have something to say slowly. Ok? The enemy has taken over the whole world, tyrannical and rude? This primordial black hole is a good fit.
