If you run into a jam, for ordinary people, it would already be an incredibly lucky misfortune. But for Liuzi, it's standard operation, and what is her lucky attribute? It's a pistol exploding in the chamber, sending fragments of the bullet casing through the seal and embedding into the shooter's main artery.
Yes, that means if someone puts a pistol to the back of Liuzi's head and pulls the trigger, there is a 72.3% chance that the pistol will explode and kill the shooter, and the remaining 27.7% would result in a jam because the state of calamity doesn't occur. In other words, there is no chance the gun could fire smoothly.
But are there exceptions? Of course, there are.
