The captain propped himself up on his hands, struggling to get to his feet. He mumbled to himself, "I...must ensure there are no more problems. This time, I betrayed all my comrades and snuck out to fight him alone. It's to end this fated entanglement once and for all! I will defeat you!",Iron Man shrugged, sighing helplessly: "I hope so. For some reason, I'm on edge right now, with a bad feeling, like an impending apocalypse is coming.",Sighing, Tony shook his head as if trying to shake away the last vestiges of regret. Then he said: "Ten years ago, based on my father's research, I independently developed this time-travel device. My intention was to use it to travel back in time and prevent the tragedy that befell my parents. However, I didn't know what impact altering the past would have on the future. Perhaps those I cherish here would disappear as a result, so the time journey never came to pass."。
