In Wushan Residence, a strange old man died suddenly and mysteriously in front of Iron Triangle, leaving behind a strange bronze fragment engraved with the text of the "IT" organization. An old tape recorder automatically plays the cold warnings of "Time is running out," "The key," and "It's watching." Zhang Qiling confirmed that the bronze fragments were related to the ultimate, and pointed out that the fatal marks on the old man's hands pointed to "Xisha". When the storm rises again, Iron Triangle must solve the mystery of the fragments in Hangzhou, which seems calm but has turbulent undercurrents, face "it"'s pressing step by step, and face the giant bronze door that may open in advance.
