Auditorium.
Su Ming'an touched the black earrings on his ear. He had been monitoring the surveillance here for a long time.
He took out a pen and started writing and drawing:
...
[Su 1: Entering the laboratory → Hui Bai restrains Su Ming'an → After the scalpel falls, Su Ming'an does not die and continues to live on in Su Liujin's body → As an art teacher, attends class with Hui Bai → Encounters Wu Yi after class → Meets Xue Jiarui with Wu Yi]
[Su 2 (Me): Entering the laboratory → Hui Bai restrains Su Ming'an → After the scalpel falls, Su Ming'an dies, consciousness transfers to Shadow clone. To prevent the face from being too conspicuous, wears Su Wensheng's black earrings, presenting as Su Wensheng's appearance → As a transfer student, attends class with Lu Xinyi → Goes to the auditorium to watch surveillance after class]
...
Su Ming'an put down the pen.
