...
A dreamless night.
In the morning, Lu Xun woke up, got dressed, and yawned as he walked out of the bedroom.
Sounds were coming from the kitchen where his aunt was busy.
Xie Manyu had also gotten up early and was doing homework in the living room. Sometimes she furrowed her brows in deep thought, and sometimes she had a sudden realization, her pretty face lighting up with the excitement and joy of solving a puzzle.
Maybe she was too absorbed, immersed in the sea of knowledge, she was completely oblivious to the fact that her brother was already beside her.
Lu Xun quietly approached her from behind, crossed his arms, and watched her doing math problems with great interest.
After watching for a while, he was somewhat surprised.
Because these were second-semester high school math problems!
Xie Manyu was taking on high-level challenges, and she had solved most of them correctly.
