His mentor, Dr. Chen, was one of the victims of this disaster. When Lin Feng sneaked into the steel tomb and tried to piece together the truth from the echoes of broken data, he discovered that the disaster was no accident. A ghost hidden deep in the data stream begins to talk to him, leading him to uncover a terrifying secret about human technology and existence itself. Under the suffocating pressure and psychological oppression of the deep sea, Lin Feng must identify who is the real enemy before being swallowed by the abyss.
