Returning from a Reverse Journey

In the near future, a deep-diving engineer of the "Struggle" who died in the line of duty was "intercepted" by the "time project" from the moment before his death. He must remain anonymous and lead a special team to perform observation and intervention missions at multiple historical "singularities" that determine the direction of civilization. He must find the meaning of his personal existence and his way back between saving the future of his country and maintaining historical ethics.
