Ember Record: I Am a Tombkeeper in the World of Immortality in the Wasteland

In the world of immortality with depleted spiritual energy, the earth has become a radioactive wasteland due to the ancient war between immortals and demons. Monks need to wear gas masks and rely on "spiritual core batteries" to drive magic weapons. Mortals have been implanted with "pseudo spiritual roots" through genetic modification, but the success rate is only 5%. Lin Jin is an "ancient tomb restorer" who acquires incomplete skills by excavating ancient monks' tombs, but needs to fight against the "Grudge Al" (a monster that combines the ancient monks' spiritual consciousness and artificial intelligence) remaining in the tomb. The monks need to cultivate the "Death Vein" first (simulating the state of death to reduce spiritual power consumption), and then activate the "Life Aperture". The levels are divided into: Dead wood realm (suspended death to collect breath) → rotten soil realm (reorganization of the body) → embers fire realm (burning longevity burst) → Nirvana realm (near-death epiphany).
