After Monsters Invaded, My Students Filled the World

[Updates paused for now. Returning at a later date.] As the corruption spread, teacher Ling Jiu was preparing for her first class after a long holiday. But when she pushed open the classroom door, she found a monster with eighteen tentacles, a Godzilla whose head had punched through the ceiling, a gaping-mouthed monster, and a host of terrifying ghosts surrounded by eerie fog. Ling Jiu: ...Never mind. There's no such thing as a bad student. And so the people's teacher worked diligently, while the monsters trembled in fear. "Tentacles, have you turned in your math homework? Don't give me excuses! You've got eighteen hands. How could you not finish?" "Godzilla, where are you looking? At the blackboard! Are there words on the ceiling?" "And you, Gaping Maw! Why are you grinning so wide? What's X equal to? Do you think grinning during the exam will earn you points?" "You are the worst class I've ever taught!" Later, when the surviving humans assessed the threat levels of the various contaminants, they discovered that the S-rank contaminants had no weaknesses, except that whenever they saw Ling Jiu... they became unusually well-behaved. The giant beast that had been arrogantly breathing fire just moments before spotted Ling Jiu among the human group and immediately clasped its hands behind its back, sitting up straight like an elementary school student. A crimson blood mass hidden in the ghost fog trapped everyone in a movie theater, but after seeing the strict teacher sitting in the front row, it obediently opened the doors and let them out, then handed in a deeply moving review of the movie. The sea monster with eighteen tentacles raised enormous waves, but just before the spray could wet Ling Jiu's clothes, it stopped at the last possible moment, then performed a flawless set of broadcast exercises using all its limbs. == An utterly ordinary teacher had arrived at the base. Qin Yuan, the strongest fighter, had slaughtered half a city. His contamination level was off the charts, his eyes were bloodshot, and he was on the verge of losing his reason. Not a single fully armed soldier dared step forward to guide Qin Yuan into the purification room. Until a petite woman carrying lesson plans and books approached him. With nothing more than a tut, muscle memory took over, and Qin Yuan hurried into the purification room on all fours under Ling Jiu's watchful gaze. Everyone: ??? Ling Jiu adjusted her glasses, her expression calm. "Oh, he's my student." She pointed at the ones flying overhead and running along the ground. "They're my students too." "Those two are our class monitor and PE rep. They loved fighting back when they were in school." As she spoke, she tossed a piece of chalk at them. The two monsters locked in combat immediately separated and obediently went to stand in the corner for punishment. Everyone: ...Huh? Ling Jiu: What can I say? After teaching for long enough, you might accidentally end up with students all over the world. tips: 1. The premise is that monsters are good and humans are bad. Early on, some vulnerable groups will suffer injustice and hardship, lose faith in the human world, and join the heroine's monster faction. They will grow stronger and rebuild a new base with her. 2. I drew the cover myself, so please praise me (doge). Theme: Respect teachers and honor their teachings
