Crossfire Through Time

Retired sniper Zhang Zongheng becomes the only 'immune body' resistant to spacetime radiation after an accident, and is coerced by the mysterious organization 'Long River' to travel through time and fix historical anomalies. He bears the curse of 'existence erosion'—with each jump, the real world's memory of him fades. Witnessing history's cruelty and the organization's dark secrets, he is torn between maintaining the 'correctness' of established history or rewriting a chance for the suffering at the cost of his own annihilation. This is a war exclusive to time travelers, with no return in victory or defeat.
