The Sky-Annihilating Emperor could converse with Lu Xiaoyou through brain-to-brain communication, and she could easily transfer her understanding of this world to him.
A week before the exam, Lu Xiaoyou was tutored by Long Xiliang, but no matter how Long Xiliang laid out the key points from the textbooks, Lu Xiaoyou just couldn't memorize them.
Moreover, if she got a question wrong, Long Xiliang would forcefully "punish" her.
The punishment was so intense that fireworks exploded in Lu Xiaoyou's brain, and after the explosions, she forgot all the math formulas and English grammar she had memorized.
Besides, with the Sky-Annihilating Emperor, this cheating artifact, at her disposal, why should she spend time and brain cells on rote memorization when she could just lie down during the exams?
Lu Xiaoyou had always been the kind of person who did whatever was most comfortable.
