There were four entries in obj.funcs, select option 3 to enter the hidden one.

0x00401d38      8b052aa60c00   mov eax, dword [obj.modded] ; [0x4cc368:4]=20
0x00401d3e b    83f814         cmp eax, 0x14               ; rax

In option 3, it requires obj.modded to be 0x14 to go on. obj.modded is increamented by one every time enter option 1, so selected option 1 for 20 times then option 3, it printed the flag.
