The Legend of the So

Tony gritted his teeth in anger: “Damn it! We’re too late!”,Iron Man patted Hulk on the shoulder. "Calm down. Everyone here is worried about Captain, not just you. As long as you stay calm, I'll treat you to twenty servings of Boston roast pork back at base." Looking at Hulk shamelessly sticking out a hand, Tony said helplessly, "Fine, fine, fifty servings then!",Sighing, Tony shook his head as if trying to shake away the last vestiges of regret.

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."。
