Lin Ke'Er always had a strong urge to preach.
This personality made her have a natural impulse to become a teacher.
Moreover, Lin Ke'Er's preaching was always heartfelt, with a gentle reassurance, so it rarely made people feel annoyed.
Just like now, even though Shen Sui was already a professional fifth-tier Life Card Master, Lin Ke'Er, who was only a first-tier Life Card Master, still couldn't help but remind Shen Sui about various things to watch out for in the competition.
At first, Shen Sui just listened half-heartedly.
But the more he listened, the more he felt something was off.
Because much of the knowledge and experience Lin Ke'Er mentioned about the events didn't seem like what low-level Life Card Masters of one or two tiers would have access to.
"Teacher, didn't you also compete before?" Shen Sui asked with a hint of curiosity.
Lin Ke'Er paused, and for a moment, a sorrowful look flashed across her face, but she quickly concealed it.
