刀片模板引擎不会产生截面

Trying to @yields the @section('content') from welcome.blade.php view, but I am unable to get any result on the webpage.

views/layouts/master.blade.php

<!DOCTYPE html>
<html lang="en">
<head>
    <title></title>
</head>
<body>

    <div class="container">
        <p>Hello World!</p>
        @yield('content')
    </div>

</body>
</html>

views/welcome.blade.php

@extends('layouts.master')

    @section('content')
        This is content!
        @endsection

Displaying Hello World! on the webpage, but not yielding the content from the extended layout.

I have checked the code several times, but unable to find the solution. I have used this templating engine before, but it worked fine. Unfortunately, it doesn't making any sense this time.
