To deal with trivial cases, you have to wear three layers of soft armor, carry more than a dozen antidotes, and lay out seven or eight traps and escape routes.
When encountering a seemingly weak demon/enemy, he imagines a world-ending crisis, uses all his strength (invincible defense blocks the attack, and kills the opponent instantly with one blow), and then collapses afterwards.
His strength is misunderstood (thinking that he has hidden secrets/special magic weapons). He was involved in a big incident and was forced to take action.
Every time he makes a move, he is earth-shattering (due to over-preparation and invincible skills), his reputation grows and his troubles increase.
Repeatedly jump between "extreme caution" and "forced to show off", becoming a "cautious brave" who makes enemies fearful and colleagues speechless.
Plot summary: Beat up a little thief? First set up a killing array! Is the opponent a chicken? I open the invincible shield! Jianghu: Please stop being cautious (pretending)!
