Tianqiong Academy, near the end of school hours, the weather had already turned grim, with the classroom air feeling hot and sticky, leaving everyone struggling to breathe.
Even with the windows flung wide open, a cool breeze seemed elusive.
Those who studied here were not from extremely impoverished families, and everyone was reasonably particular, so there weren't any unpleasant odors.
Gu Jiao sat in the last row, Mu Qingchen to her left, and the back door to her right.
From her spot, she could still breathe in enough fresh air.
Zhou Tong in the front row was nodding off.
Partly due to the stifling heat, and partly because he had stayed up late again to paint.
During the lecture, Master Gao was explaining the Gougu Theorem, which was what Gu Jiao had learned as the Pythagorean Theorem in her previous life.
"Zhou Tong!"
Suddenly, Master Gao called out a name.
Zhou Tong jerked to attention, standing up with a befuddled expression.
