The city's silent dome suddenly collapsed, instantly releasing deadly ginkgo leaf blades. Xiao Yang, an intern of scientific researcher Chen Yuan, was unfortunately killed. In grief, Chen Yuan discovered that the blood mist in the air condensed into mysterious coordinates, guiding him into the abandoned mine. Deep in the mine, he encountered a resin stalker transformed by engineer Lao Li. At the critical moment, explorer Lin Yu and sonic hunter A Ye came to help.
As they explore further, they discover a network of clematis plants hidden in the mines that judge sins, and a spiritual abyss that contains the memory of human sins. It turns out that plants have been recording human sins for thousands of years. When the sins accumulate to a critical point, the "Abyss Requiem" will be activated, releasing the power to destroy civilization. Chen Yuan firmly believed that Lao Li, who had participated in the core project of the Silent Dome, had the key secret to uncovering the truth of the disaster hidden in his blood. This judgment was also confirmed by the subsequent blood bead patterns discovered.
Facing the upcoming "Abyss Requiem", Chen Yuan, Lin Yu, A Ye and the mysterious sign language girl Zhenzhen formed a team. They used sound wave technology to fight against the plant network, trying to prevent this disaster that could destroy mankind. The four of them went deeper into the crisis-ridden mine, and the truth gradually emerged, but what awaited them was a more terrifying unknown and the final showdown of fate.
