Laravel - __construct function being ignored

I'm trying to use the __constructor from the extended class (AdminController extends AdminBaseController) but aparently it's not working and I have no idea of what can be, here you can see both of my classes:

AdminBaseController.php

class AdminBaseController extends Controller
{
    public function __construct(){
        if (!Auth::user()){
            return view('admin.pages.login.index');
        }
    }
}

AdminController.php

class AdminController extends AdminBaseController
{
    public function __construct(){
        parent::__construct();
    }

    public function index()
    {
        return view('admin.pages.admin.index');
    }

    public function ajuda()
    {
        return view('admin.pages.admin.ajuda');
    }
}
