[Western Crossover] My Two Friends Looking for Their Sons

I accidentally transmigrated to another world and made two friends. One had lost his memory, and the other had lost his too. "Do you remember your names?" "No. Call me W." "Jack. I forgot my last name." Sigh. My two friends were both exceptionally talented, each a master of their craft. W was a brilliant doctor, widely learned, and single-handedly helped build our country. Jack was at home in every corner of society, from respectable circles to the underworld, and was a real expert in intelligence work. Both my friends doggedly searched for sons they couldn't even remember, and they bonded over it so deeply that they nearly left me out when they swore brotherhood. "So, did you find your sons?" "..." x2 Then we transmigrated again, and my two friends finally got their wish. Only... "Jack, this is your clever, kind, physically frail son?" "W, this is your well-behaved, lively, innocent, headstrong son?" Jack touched his still-beating conscience and had no answer. W, on the other hand, was perfectly confident, saying something about how boys change dramatically as they grow up. In short, I have two friends. One of their sons is a vigilante, and the other is a vigilante too. They both have some inexplicable connection to bats. My life has become far more dangerous, exciting, and full of twists and turns. Oh well, what can I do when I'm stuck with these two friends? Theme: On the power of the Face Fruit
