Grain of Eternity - Episode 4

In this tense episode, a man urgently needs a military-grade quantum battery to survive beyond two hours, as the pod sustaining him only delays the inevitable. Outside, a deadly mecha is targeting him due to timeline changes, and he plans to intercept it at the armory. Another person warns him not to touch them roughly, revealing the use of monomolecular wire as a defensive weapon. They discuss a past failed mission at Outpost Three, where only two survived, including the observer who has witnessed repeated deaths. Suddenly, alarms trigger as an intruder is detected, and termination is authorized, leaving their fate uncertain.
