Lightning protection: A very clichéd joke. The heroine is very powerful and is a Hong Kong and gangster cadre. In the early days, everyone in the high school hated her because of the green tea system.
Ps: If you especially like the spell return war, watch it carefully. It's a bit like the ten-year period has come and the master wants you to go home and inherit the family business (it's a slap-in-the-face kind of novel). The heroine's character is a bit dark.
The heroine was sent undercover by the leader of the gang - Mori Ogai, who specializes in magic. Unexpectedly, there was a trickster named Green Tea. Later, she changed her identity and revealed her true identity, which made everyone slap her in the face (dark laughter).
Note: Green Tea is not a good person. The system can change the favorable impression of people around him towards Green Tea (brainless pet) without affecting everyone in the literary field, including the heroine. Therefore, the heroine hates Green Tea, and is hated by everyone in the high school. Later, when Green Tea's true identity is revealed, everyone is freed from the effects of the system.
Let me reiterate again: It's a very old-fashioned joke. Green Tea is really not a good person. The system is equivalent to brainwashing, so people with higher education will be biased towards her (don't worry, she will wake up later)
Intention: If no one writes it, I will write it myself
