An unknown man who called Su Nian twice from an unfamiliar number. The first call was garbled with static, only saying 'Careful... Zom...' and 'Hurry... Hurry...' The second call was clearer, with the caller breathing heavily and urgently telling Su Nian to 'Find somewhere... hide...' and 'Run! Leave the city...' Su Nian suspects it may be Lu Chen, who disappeared six years ago, since he knew her name.
