She was practicing while learning, two rounds of a slow exercise called "Ba Duan Jin" which left her feeling fatigued. Chen Li was surprised, she knew how strong Li Ming was, yet she could only hold up for an hour before she lost all her combat strength.
Turns out, she could only get through this slow exercise twice before she had to stop?
The Ba Duan Jin was an exercise many college students practiced, including Chen Li. She had even practiced it alone at home, although she hadn't done it in a while and the previous effects weren't so noticeable.
Stunned, after hearing Li Ming's explanation, she immediately kept this in mind, and quickly told her mother about the "Ba Duan Jin" exercise.
Chen Li's mother thought for a moment before deciding to practice along with her daughter. Chen Li then persuaded her own daughter to join them.
