NotFoundHttpException in RouteCollection.php

I create a fresh laravel 5 project and the routes file is as bellow.

Route::get('/', function () {
    return view('welcome');
});

When I access it with http://localhost/mysite/laravel/public/ it works fine and goes to the welcome page. But when I modify the route as bellow and access it as http://localhost/mysite/laravel/public/blogs an error occurs.

Route::get('/blogs', function () {
        return view('welcome');
});

Error:

The project is a fresh one and I didn't change any file except the route. What is the reason for this error? I am using laravel 5.x and XAMPP. I read all the similar questions in stackoverflow but still I couldn't find an answer please help.
