Tenglong Mansion is located in the prime commercial area of C city, but due to the high price, many floors are still unpopular. Gu Qing, the new administrative supervisor, is a wonderful beauty. From her first day at work in Tenglong Mansion, she has encountered chillingly strange events and even blood-curdling tragedies one after another. A conspiracy that seems to have a lot to do with her is secretly brewing. Yuwen Shuxue is the network administrator of Tenglong Group, tall and thin, with messy hair, a face of beard, dark and thick eyebrows, and unkempt. Such an unassuming and ordinary employee, but his movements were very secretive. Every time something strange happened, he seemed to know it like the back of his hand. When Gu Qing was in danger, Yu Wen came to his rescue and at the same time told Gu Qing his true identity. Liu Tianming is the chief of the criminal police in C city, an excellent and tough man, no matter how ferocious and tragic cases he handles, he is firm and calm. However, facing the series of unexplainable events in Tenglong Mansion, Liu Tianming also begins to examine his own judgment, and he can only rely on his own flesh and blood, and together with Yuwen and Gu Qing, he walks righteously towards the unknown front. In this Tenglong Group, there are also cautious middle manager Chen words, arrogant and shadowy Du hear Tao, shrewd and capable chairman Pu Yuan, and what role they play here? This is a very ordinary looking office building, however, when we open our eyes to see, perhaps this is precisely where we are working.
