The soldier and Li Zhu separated midway. The former rushed to the bathroom to lead Lu Yizhou away while Li Zhu made a beeline to Zhao Bolin's office. Because Lu Yizhou had just come out, the door was not locked, much to Li Zhu's relief.
As Professor Zhao's direct student, Li Zhu had actually entered this office countless times. But every single time, he could only stare at the side door leading to the laboratory in curiosity. However, it would be different today!
It seemed like the Goddess of Luck was siding with him because as soon as Li Zhu entered, he saw a familiar brass key on the table right in front of him! Heart leaping to his throat, Li Zhu snatched the key and held it with sweaty hands as though it was a life-saving item. The smoke bomb stung his eyes and his heart was beating so fast that he felt faintly nauseous. His hands shook so badly that he could not insert the key properly into the hole despite trying a few times.
