From the Start, the Heavenly Might System Cracked Down on Crime

My sister was stopped and harassed by a thug, but thankfully, a kindhearted stranger stepped in to help.

I couldn't help worrying: what if she ran into indifferent bystanders and no one came to her rescue?

What if it happened somewhere secluded, with no one else around to call for help or the police?

Should I have my sister learn self-defense or boxing so she could fight off criminals? What if she faced several of them at once?

Or should I just pray that nothing like this ever happens to anyone in my family?

Maybe I should make lots of money and hire bodyguards?

I choose to solve the problem with knowledge...
