Song of Heavenly Purity

I suffered a lot of humiliation in my previous life and left that world in an extremely ugly and embarrassing way. But God actually gave me a second chance, and also retained the memories of my previous life: chemistry, physics, mathematics, ancient poetry, English, calculus... In this case, I must make a new start in this different world! The sky is clear and Li sings, and the setting sun rises in my heart. This novel and its characters are purely fictitious.
