Everyone Travels Through Time, Except Me

All the teachers are time travellers. Except me. * My name is Xiaochuan, I am twelve years old and a native of Xiuzhen Continent. One day, something calling itself "the system" came to me. The system said that a time traveler appeared in the world of cultivation, posing a serious threat to the world. And my mission is to sneak into them and become an undercover agent, secretly learn their skills, scratch their car seat cushions, fight against the barbarians under cover of hardships, and drive these time-travelers back to their hometown. Comes with a copy of "The Traveler's Guide to Disguise". ** I relied on my excellent disguise skills to sneak into the time travel sect. This group of time travelers is indeed not simple. The eldest brother is the boss of the family business. He is handsome and doesn't talk much. Wherever he goes, classic novel plots always happen. The second senior sister is a popular domestic entertainment star. Her acting skills are explosive and she is surrounded by scandals. Her biggest hobby is to rate the men who pass by. The third senior brother, the top student in high school, always has a dead look on his face, and no one knows his true identity as a chuunibyou. Oh yes, and Master.

Known as the ancestor who traveled through time. *** As a fake time traveler, my life is always filled with fear. So I strive to demonstrate proficiency in time-travel knowledge inadvertently.

The third senior brother's eyes widened: "But this is a high number!" I said calmly: "But I am a genius!" 2023.01.07 Purpose: Different paths lead to the same destination
