Laravel how to add records with create function in controller?

NewsController.php

This is the contoller and i use the create function to add record to the database but when i add all records will be empty

public function insertNews() {
    $attribute = [
        'Ntitle'   => 'News Title',
        'Ndesc'    => 'News Description',
        'Naddedby' => 'News Added By',
        'Ncontent' => 'News Content',
        'Nstatus'  => 'News Status'
    ];
    $data = $this->validate(request(), [ 
        'Ntitle'   => 'required',
        'Ndesc'    => 'required',
        'Naddedby' => 'required',
        'Ncontent' => 'required',
        'Nstatus'  => 'required'
    ], [], $attribute);
    News::create($data);
    return redirect('all/news');
}

and i use dd() to show the record and it will show with the token and all other values

dd(request()->all()) 

news.blade.php

and this is the blade file that contain the form that i sent to the controller

<form action="" method="POST">
    
    <input type="text" name="Ntitle" value="" placeholder="News Title"><br />
    <input type="text" name="Ndesc" value="" placeholder="News Descrption"><br />
    <input type="number" name="Naddedby" value="" placeholder="News Added By"><br />
    <textarea name="Ncontent" value="" placeholder="News Content"></textarea><br />
    <select name="Nstatus">
        <option value="Active" >Active</option>
        <option value="Pending" >Pending</option>
        <option value="Disabled" >Disabled</option>
    </select><br />
    <input type="submit" value="Add News">
