Shen Yan, the recognized king of rolls in Tangxi No. 1 Middle School - the gunshot at 5:20 in the morning was more accurate than the alarm clock. Seven years ago, a "Study Book" fell into his hands out of thin air: every shot and every breath he practiced would turn into ink seeping into the paper in the book. There is ink on the book, and the skill will not deceive others. When I was seventeen, a chat group called "Wanjie Pantry" came to my door. The people in the group came from worlds he seemed familiar with: the sick old emperor, the red-haired vicious dog, and the young man who was destined to die on the execution platform. He seems to have read all these stories, but the names are all missing one word. Practice guns and kill your peers; keep accounts and keep them forever. Whoever said his kung fu was fake would show him the ink on the book in the open, one stroke at a time.
