Qi Ember Dream Battle

After a hundred years of catastrophe, oxygen has become the only hard currency. The city's oxygen supply valves are under unified control by the central government. Everyone's breathing is a number, and every time the air volume is low means a countdown. Lin Che is a "dream tracer" who can penetrate deep into the subconscious layer contaminated by nightmares and fish people out of the spiritual dead. One day, he discovered something in the deep dive zone that shouldn't exist - a nightmare nest fed painfully by living people. The energy supply pipeline of that nest is connected to the central backbone network. Capacity reduction is never due to insufficient resources. Someone is calculating how long an ordinary person's fear before death is enough to make that thing sleep longer. Lin Che decided to continue investigating, even if the person beside him was Gu Huai, who only knew how to follow procedures. They went deeper and deeper, and finally unearthed the truth beneath the gray realm: they were not the first to discover this. It's just that none of the first seventeen batches came back alive.
