laravel Cannot save records to DB

I am building a blog system with laravel.

Now I have a blogger table that has a name, email address, and password.

In addition to the default account table, I want to save a profile image and introduction. They belong to the blogger table in my case. But I cannot save those two records.

I cannot figure out why profile records cannot be inserted into my DB.

And my user role is a blogger.

I can see ?_token on the url.

blogger table

Schema::create('bloggers', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });

blogs table

Schema::create('blogs', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->integer('user_id')->unsigned();
            $table->foreign('user_id')->references('id')->on('bloggers');
            $table->string('image');
            $table->string('introduction');
            $table->timestamps();
        });

blogger.php

public function blogs()
    {
        return $this->hasMany(Blog::class, 'user_id');
    }

blog.php

public function user(){
        return $this->belongsTo(Blogger::class, 'user_id');
    }

bloggersController.php

public function store(Request $request, Blogger $blogger_id){
        $blogger_id = DB::table('bloggers')->where('id', $blogger_id)->get();

        Auth::guard('blogger')->user();

        if($request->hasfile('image')){
            $file = $request->file('image');
            $ext = $file->getClientOriginalExtension();
            $filename = time().'.'.$ext;
            $file->move('bloggers/', $filename);

            $blog = Blog::updateOrCreate(
                  ['user_id' => $blogger_id],
                  [
                      'image'=>$filename,
                      'introduction' => $request->introduction,
                  ]
              );
      }
       return view('bloggers.create')->with('bloggers', Blogger::all())->with('blogs', Blog::all());

    }

web.php

Route::get('/create', 'BloggersController@store')->name('blogs.store');
