This is probably an idea I had a long time ago. According to normal theory, the ending of Class 1 is that Lei Ting Wanjun goes back to 10 years ago to stop Pang Tianqi's plan. Class 3 will indeed change (it can be regarded as resetting the ten-year history of Jin Shikong), but Jin Shikong has changed 10 years later. Who will go back to 10 years ago to change Pang Tianqi?
Add new person:
Xia Tiantian
Jin Shikong's new alliance leader, Jin Shikong's youngest daughter Tian Tian, was brought to Tie Shikong by Xiu ten years ago. She has a sister who is an undeveloped martial arts genius - Tian Xin, and an older brother who was number one in the KO list ten years ago - Tian Hongguang, who is now adopted by Xia Lanyong's family.
Intention: The present future is the past
