A good-for-nothing boy in real life accidentally took the whole class to a different world and embarked on a journey to another world. Rule the long river of time, hold the halberd that opens the sky, fight against the heavens, and quell all injustices in the world! (Traditional fantasy novel, single female protagonist, reasonable upgrade logic, more than a dozen level-killing enemies, the protagonist is good at complaining, attaches great importance to love and justice, has a humorous personality, but is decisive in killing, and the excitement is endless!)
I really like the beginning of this.
